b2da6f28d6d0d2c6d876309e0bc66471_0 | IBM How to serve static files from both IBM HTTP Server and an application in WebSphere Application Server - United States TECHNOTE (FAQ)
QUESTION
How can I configure IBM HTTP Server (IHS), and the IBM web server Plug-in, and my web application running in WebSphere Application Server (WAS), to serve some of my static files (JPG, GIF, CSS, JS, etc) from the IHS web server, but serve other static files from my web app running in WAS?
CAUSE
The "fileServingEnabled" property in the ibm-web-ext.xmi file in the web application, is like an ON / OFF switch.
A setting of fileServingEnabled="true" means that ALL static files will be served from the web application in WAS only. In this case, the plug-in config will use a wildcard with the application context-root like "/myapp/*". That way every URL starting with /myapp/* will be routed to the application in WAS. |
b2da6f28d6d0d2c6d876309e0bc66471_1 | On the other hand, fileServingEnabled="false" means NO static files will be served from the application in WAS. In this case, a wildcard will NOT be used in the plugin-cfg.xml file. Instead, there will be several URI entries matching the URL-Patterns from <servlet-mappings> in the web.xml, like "/myapp/servlet1" and "/myapp/index.jsp". Requests for dynamic content matching the URI entries in the Plug-in config, will be routed to the application in WAS. But everything else (static content) will be handled by the IHS web server itself. |
b2da6f28d6d0d2c6d876309e0bc66471_2 | ANSWER
If you want to serve any static files (JPG, GIF, CSS, JS, etc) from your web application in WAS, you must use fileServingEnabled="true" in the ibm-web-ext.xmi file. That will cause the plug-in to use a wildcard entry for the context-root of your web application. For example, if the context-root is "myapp", then there will be a URI entry for "/myapp/*" in the plug-in config, and everything starting with "myapp" will be routed to the application in WAS.
Now, if you also want to be able to serve some of the static files from the IHS web server itself, you will need to do a trick using RewriteRule in the IHS config. Here is how the trick works:
1) Create a subdirectory called "static" under the IHS DocumentRoot directory. And put the static files that you want IHS to serve into that directory. For example in the IHS document root directory (HTTPServer/htdocs/) create a subdirectory called "static". Something like this:
/usr/IBM/HTTPServer/htdocs/static/ |
b2da6f28d6d0d2c6d876309e0bc66471_3 | 2) In your web application, you will reference those files using relative references like "static/picture.jpg", or "static/mystyles.css".
Those relative references will be interpreted as URLs like this:
/myapp/static/picture.jpg
/myapp/static/mystyles.css
Keep in mind that there really is NOT any "static" subdirectory in the application. But that is ok.
3) Now, in the IHS config, you must use RewriteCond and RewriteRule to watch for these references, and redirect to get them from IHS. For example, look at these directives...
<ifModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^/myapp/static/(.*) /static/$1 [PT]
</ifModule>
It means, if the URI begins with /myapp/static/* then IHS will rewrite it to just /static/* and "pass-through". Since /static/* does NOT match anything in the Plug-in config, the request will be handled by IHS, and the file will be served from the static directory under IHS DocumentRoot. |
b2da6f28d6d0d2c6d876309e0bc66471_4 | To the user looking at the URL in the browser they will see this:
/hostname/myapp/static/picture.jpg
But, the file will really be served by IHS from here:
/hostname/static/picture.jpg
Here is another example:
If you just want to match and serve *.gif files from IHS, use:
RewriteCond %{REQUEST_URI} \.(gif)$ [NC]
RewriteRule ^/myapp/(.*) /static/$1 [PT]
If you just want to match and serve *.gif, *.css and *.js files from IHS, use:
RewriteCond %{REQUEST_URI} \.(gif|css|js)$ [NC]
RewriteRule ^/myapp/(.*) /static/$1 [PT]
Which assumes the files themselves are placed in [IHS_DOC_ROOT]/static/.
4) For the static files in the application, you will need to put them in some other directory that is NOT called "static", for example "images/sunset.jpg" would be a directory and file in the myapp application. This URL request, would be handled by the Plug-in and sent to the application in WAS:
hostname/myapp/images/sunset.jpg |
b2da6f28d6d0d2c6d876309e0bc66471_5 | So, by using the trick described above, some static files will be served from IHS, like:
/hostname/myapp/static/picture.jpg
But other static files will be served from the web application running in WAS, like:
/hostname/myapp/images/sunset.jpg |

c355b4474bf3f762290b3fd07f669934_0 | IBM Why does IBM Datacap 8.1 appear to hang, requiring a restart of all components? - United States hang; non responsive; timeout; Admin retry; Engine retry TECHNOTE (TROUBLESHOOTING)
PROBLEM(ABSTRACT)
Why does IBM Datacap appear to hang, requiring a restart of all components?
SYMPTOM
The Datacap system appears to become non-responsive, requiring a restart of all components to get it working again.
CAUSE
The cause is due to a malformed SQL query string. From the client perspective, it was reported to occur during logon via TMWeb, and Thick Client. Another case was from a user that was doing a Thick Client query.
TMServer has an feature where it will retry any command that results in error, based on the settings in the registry. The settings reflect the number of retries to do and the time interval to wait. The default settings have a duration of 16 minutes, which gives the appearance that the TMServer has hung. |
c355b4474bf3f762290b3fd07f669934_1 | DIAGNOSING THE PROBLEM
Collect and examine the TMServer log. Look for multiple instances (6-12) of an ADO error, indicating a bad query was executed. This information can be used to identify the user that is causing the problem
RESOLVING THE PROBLEM
While bad queries should be avoided, the following will allow TMServer to respond faster, should a bad query happen:
1. Stop all Datacap applications, then stop the TMServer.
2. Change the following registry entries on the TMServer box: |
c355b4474bf3f762290b3fd07f669934_2 | *
*
* HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Datacap\TMS\InterThread (REG_SZ) Admin retries HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Datacap\TMS\InterThread (REG_SZ) ADO retries HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Datacap\TMS\InterThread (REG_SZ) Engine retries
*
*
*
* HKEY_LOCAL_MACHINE\SOFTWARE\Datacap\TMS\InterThread (REG_SZ) Admin retries HKEY_LOCAL_MACHINE\SOFTWARE\Datacap\TMS\InterThread (REG_SZ) ADO retries HKEY_LOCAL_MACHINE\SOFTWARE\Datacap\TMS\InterThread (REG_SZ) Engine retries
*
*
*
*
*
*
*
*
*
*
*
*
*
*
*
*
3. Restart the TMServer, then start the Datacap applications in reverse order.
Please Note: Since these are considered tuning parameters, you will need to test to see what settings work best for your system.
Note: for Datacap 9.x, the registry entry name is singular, as in 'Admin retry' or 'Engine retry'. |
6f09a8c5ef85188c55aca72e7935bef4_0 | IBM Configure IBM Content Collector to use SSL to communicate with IBM FileNet P8. - United States TECHNOTE (FAQ)
QUESTION
How do I configure IBM Content Collector (ICC) to use SSL to communicate with IBM FileNet P8 for all components?
CAUSE
ICC communicates with P8 in several different components. Depending on the API used for the various components, P8 certificates need to be installed in multiple places.
ANSWER
Do the following steps to install P8 certificates. Depending on your business requirements, you may not use all of the components so some steps may not be necessary. |
6f09a8c5ef85188c55aca72e7935bef4_1 | * First obtain a P8 server certificate by accessing the P8 Content Engine ping page using this URL: https://<ce_server>:<ssl_port>/FileNet/Engine
From the browser, view the certificate and copy it to a file. Use it for later steps.
Do not use the MTOM page as it may not produce the same certificate that ICC requires.
* Perform this step if you are going to run ICC Initial Configuration to create new document classes in P8 object store. * To import the certificate, issue the following command, whereICCInstallDiris the directory of your Content Collector installation andP8CertificatFileis the certificate for the FileNet P8 server: "ICCInstallDir\java\jre\bin\keytool.exe" -import -file P8CertificateFile
-keystore "ICCInstallDir\java\jre\lib\security\cacerts" -alias afup8
* At the password prompt, enter the password for the JRE keystore. (The default password is changeit.)
* Enterywhen asked whether to trust the certificate. |
6f09a8c5ef85188c55aca72e7935bef4_2 | * Run ICC Initial Configuration and you should then be able to validate the connection with P8 using SSL. |
6f09a8c5ef85188c55aca72e7935bef4_3 | * Perform this step if you are going to run task route archiving to P8: * Add the P8 certificate into the Windows Trusted Root Certificate Authorities via the Microsoft Management Console.
* For more details instructions, refer to this document:
http://www-01.ibm.com/support/docview.wss?uid=swg21610358 [http://www-01.ibm.com/support/docview.wss?uid=swg21610358] |
6f09a8c5ef85188c55aca72e7935bef4_4 | * Perform this step if you are going to retrieve, restore, or search for documents from P8: * Start ikeyman from ICC-install-directory\AFUWeb\ewasfor the ICC embedded web application server.
* In the ikeyman utility, select Key Database File>Open, and select PKCS12as key database type.
* In theLocationfield, specify theWAShome\profiles\profile name\config\cells\cell name\nodes\node name\trust.p12file.
ReplaceWAShome,profile name,cell name, andnode namewith the proper values of your web application server installation.
* Click OK.
* When prompted for a password, enter the password. ClickOK. The default password is WebAS.
* Under theSigner certificateslist, clickAddto add the P8 certificate.
* Exit ikeyman utility and restart IBM Content Collector Web Application service. |

ccc5de8e865deebd684e3cc5d7c41f59_0 | IBM Using dblook and ij to work with the embedded Apache Derby in WebSphere Portal - United States TECHNOTE (TROUBLESHOOTING)
PROBLEM(ABSTRACT)
IBM WebSphere Portal 6.1 uses an embedded version of Apache Derby out of the box. However, there is no longer a graphical tool such as CloudView (as with Cloudscape 5.x). In order to obtain the data and structure of the WebSphere Portal database, dblook and ij utilities can be used to accomplish such goals.
RESOLVING THE PROBLEM
Before proceeding with the following, it is strongly recommended that you back up your Derby database. Make a copy of <wp_profile>/PortalServer/derby/wpsdb to a backup directory. Since the version of Derby used in WebSphere Portal is embedded, you must stop the Portal server before you can access the database although you can always work on the backup copy.
NOTE: For simplicity, we will omit the extension of the utilities. You should add ".sh" or ".bat' depending on the platform. |
ccc5de8e865deebd684e3cc5d7c41f59_1 | There are three primary utility tools that are installed with WebSphere 6.1, "dblook", "ij", and "sysinfo", under the <was_root>/AppServer/derby/bin/embedded directory. The sysinfo utility generates information about the operating system, the Java version and classpath, and the Derby driver files and version information.
dblook utility
The dblook utility is used to view the database structure (in DDL - Data Definition Language) for a specific database.
The usage is dblook -d <databaseURL> [options], where databaseURL is in the "jdbc:derby:<database>" format. The <database> should be given as a full path, such as C:\IBM\WebSphere\wp_profile\derby\wpsdb.
Commonly used options include: |
ccc5de8e865deebd684e3cc5d7c41f59_2 | *
*
*
*
*
*
*
*
*
*
* Examples:
*
*
* dblook -d jdbc:derby:C:\IBM\WebSphere\wp_profile\PortalServer\wpsdb -o C:\temp\wpsdb_ddl.sql
*
*
*
*
* dblook -d jdbc:derby:C:\IBM\WebSphere\wp_profile\PortalServer\wpsdb -z release -o C:\temp\wpsdb_ddl.sql
*
*
*
*
* dblook -d jdbc:derby:C:\IBM\WebSphere\wp_profile\PortalServer\wpsdb -z release -t user_desc -verbose -o C:\temp\user_desc.sql
*
*
ij utility
The ij utility is a command line SQL processor. It can be used to run DDL for creating database, tables, indexes, and so on. In a WebSphere Portal environment, it would typically be used for exporting data or making simple changes (when advised by IBM Support).
To start ij, simply open a command prompt or terminal window, change the directory and enter the command. You should then see the ij shell with prompt "ij>". |
ccc5de8e865deebd684e3cc5d7c41f59_3 | The following are some common commands that you may use when reviewing data in the Portal database. *
* ij> connect 'jdbc:derby:C:\IBM\WebSphere\wp_profile\derby\wpsdb';

*
*
* CONNECTION0* - jdbc:derby:C:\ibm\websphere\wp_profile\portalserver\derby\wpsdb

df5f00ce30f61b8c466198e4178b7aa9_0 | IBM How to set an appropriate number of Portal Datasource connections in WebSphere Portal - United States TECHNOTE (FAQ)
QUESTION
For a given maximum number of Portal WebContainer threads set, what should I set my maximum Portal datasource connections to?
ANSWER
When tuning WebSphere Portal at version 6.0 and beyond, one of the concerns that arises is how should one tune the maximum number of Portal datasources. Portal can and does make heavy internal use of datasources, so miscalculating this (maximum) value can have a significant impact on system behavior. Out of the box, the default maximum setting is 50. This may or may not be sufficient for any given system. |
df5f00ce30f61b8c466198e4178b7aa9_1 | Each Portal request may make any number of database (DB) requests ranging for none to several.. Further, customized portlets and PPR (Parallel Portlet Rendering) may cause several concurrent DB requests. By default, the maximum number of WebContainer threads is also set to 50. Therefore the ratio between the maximum number of Portal datasource connections to the maximum number of Portal WebContainer threads is 1:1. Support has found that this ratio is often too low for the best performance. In the past, there have been recommendations of this ratio as high as of 2:1 or even 2.5:1.
However, these values caused concern in large deployments where the TOTAL number of maximum datasource connections might start to place a strain on backend resources. Recent analysis suggests that these ratio values may be safely reduced to 1.25: 1 for all Portal datasource, with the exception of the jcrDB when WCM is used extensively. In this case, we recommend a ratio of 1.5:1 |
df5f00ce30f61b8c466198e4178b7aa9_2 | -----------------------------------------------------------------------------------------------------------------
For example, if your system's
Maximum number of WebContainer threads is 100
then you should set your
Maximum number of Portal datasource connections to 125
for each Portal datasource.
-----------------------------------------------------------------------------------------------------------------
If during Runtime, you should find that your running out of Portal Datasource connections, you may go ahead and increase the ratio up to 2:1. Please be aware of how this might impact your backend resources and be sure to scale your database accordingly.
------------------------------------------------------------------------------------------------------------------
To find the number of WebContainer threads that are running in any particular Portal server, use the WebSphere Application Server Admin Console and go to the following location: |
df5f00ce30f61b8c466198e4178b7aa9_3 | Servers ---> Application Servers --> WebSphere_Portal (your server) --> Thread Pools --> WebContainer
To find the Data Source setting for your Portal datasources, use the WebSphere Application Server Admin Console to go to the following location:
Resources ---> Data Sources ---> wpdbDB (for example) --> Connection pools

7dfc556a4dca638c98f0acdd267eebf7_5 | Your startup does not have this. This prompted me to review the
deployment.xml from the JavaContentRepository application directory at
this location...
Portal8/wp_profile/config/cells/C001389391Cell/applications/JavaContentR
epository.ear/deployments/JavaContentRepository/deployment.xml
The contents show the following...
<targetMappings xmi:id="DeploymentTargetMapping_1335003370698"
enable="false" target="ServerTarget_1335003370698"/>
The enable=false means that you have this application set to not
autostart. Because of this it is not starting during Portal startup
and therefore is not available when the config task attempts to
communicate with it during the upgrade...and therefore causes the
problem. |
7dfc556a4dca638c98f0acdd267eebf7_6 | RESOLVING THE PROBLEM
Please make the following change in the WAS Admin Console...
Applications > WebSphere enterprise applications >
JavaContentRepository > Target specific application status > Check the
box for the WebSphere_Portal server > Click Enable Auto Start > Save
changes > restart Portal
After making this change please attempt the CF upgrade again. |
05cc9e2991b6bd8296cf7a8534b5b432_0 | IBM Tivoli Integrated Portal hangs because of Argus java.lang.OutOfMemory. - United States cacheTime; config.xml; Argus; TIP cache; TIPL2CONF; TIPL2PERF TECHNOTE (TROUBLESHOOTING)
PROBLEM(ABSTRACT)
Argus stores it's role authorizations in memory cache, and is not cleaned out unless the TIP is restarted. The "cacheTime" variable controls this, which is set to -1 by default. If the number of TIP roles is high, it can cause Java OOM errors.
SYMPTOM
TIP hangs. SystemOut.log file shows Java.lang.OutOfMemoryError:
[10/2/13 9:27:54:838 CDT] 0000002a webapp E com.ibm.ws.webcontainer.webapp.WebApp logServletError SRVE0293E:
[Servlet Error]-[/secure/isclite/tiles/nop.jsp]: java.lang.OutOfMemoryError: Java heap space at java.lang.Object.clone(Native Method) |
05cc9e2991b6bd8296cf7a8534b5b432_1 | CAUSE
By default, the ARGUS cache will not get cleaned up unless the TIP server is restarted. This normally will give the system good runtime performance. However, in cases where a large number of user/role mappings are defined, the system may run into Java memory issues causing Java OutOfMemory outages.
The cacheTime we are talking about here is Argus cache. The is used for the way the role authorizations are stored in memory by Argus and nothing related to LDAP or SSO. The Argus cache time by default we ship with in TIP is -1 which means the cache will not get cleaned up till we re-start the server.
Error from the <TIP_HOME>/profiles/TIPProfile/logs/server1/SystemOut.log
[10/2/13 9:27:54:838 CDT] 0000002a webapp E com.ibm.ws.webcontainer.webapp.WebApp logServletError SRVE0293E:
[Servlet Error]-[/secure/isclite/tiles/nop.jsp]: java.lang.OutOfMemoryError: Java heap space at java.lang.Object.clone(Native Method)
ENVIRONMENT
all environments |
05cc9e2991b6bd8296cf7a8534b5b432_2 | DIAGNOSING THE PROBLEM
Java heapdump files will be created in the <TIP_HOME>/profiles/TIPProfile directory.
heapdump.20131022.144244.20034001.phd
The Systemout.log will have have errors similar to this:
[10/2/13 9:27:54:838 CDT] 0000002a webapp E com.ibm.ws.webcontainer.webapp.WebApp logServletError SRVE0293E:
[Servlet Error]-[/secure/isclite/tiles/nop.jsp]: java.lang.OutOfMemoryError: Java heap space at java.lang.Object.clone(Native Method)
Using the memory heap dump analysis shows that Argus is the problem, specifically the instance shown inside the red line in the output of the Java memory analyzer below:
[/support/docview.wss?uid=swg21657452&aid=1] [/support/docview.wss?uid=swg21657452&aid=1]
You can also check the cacheTime variable in the <TIP_HOME>/profiles/TIPProfile/config/cells/TIPCell/commonauthz/config.xml file to confirm if it's set to "-1", which means the Argus cache will not get cleaned up unless the TIP server is restarted. |
05cc9e2991b6bd8296cf7a8534b5b432_3 | RESOLVING THE PROBLEM
The cacheTime value in config.xml is in milliseconds. TIP is shipped with the initial value of -1, which means the Argus cache will not be cleared out unless TIP restart. To resolve this issue you need to configure 'cacheTime' to non -1 value. Initially we suggest setting the value to 1200000, which is 20 minutes. After the change you will have to restart the TIP server, normally server1.
NOTE: The cacheTime variable was added in TIP version 2.2.0.0. |

b5ae55df31857b05cbca8e53da1494c0_0 | IBM Multiple logins using the same user ID - United States ConcurrentModificationException; log in; login; multiple; userid; multiple login TECHNOTE (FAQ)
QUESTION
"ConcurrentModificationException" and other errors may occur if the same user id is logged in to IBM WebSphere Portal multiple times.
ANSWER
WebSphere Portal has no built-in mechanism or configuration setting to limit the number of times a user id may log in. Unexpected behavior may occur if the same id is logged in more than once and this is not supported.
"ConcurrentModificationException" and other errors may be logged.
Most of the related issues were resolved in WebSphere Portal 5.1. However, you may still encounter exceptions or side-effects if you access the Portal in multiple browser windows using the same user id, whether or not the authentication requests take place on separate physical hosts. |
b5ae55df31857b05cbca8e53da1494c0_1 | It may be possible to prevent multiple logins by writing custom "tracking code." Contact IBM Services for assistance to undertake such a project. WebSphere Portal Development does not have any sample code.
If you wish to write your own code, some of the issues to be aware of are (this is not an inclusive list):
-- Multiple logins may take place on different nodes in a cluster. This means some cluster-wide mechanism would have to be in place to keep track of the logged-in users. Look at the WebSphere Application Server DistributedMap interface.
-- There should be a fail-safe way to track user logout (explicit logout and session timeout). Using a session listener might be a possibility.
-- If a user closes the browser without logging out, that user must wait for a session timeout before logging in again. Otherwise, there should be a "force simultaneous login" option in the login user interface.
For load testing, use unique user ids or virtual users. |

c973a17bd5901015e60f91f00ede0934_0 | IBM Seed value used during the instance creation is lost : Recovery procedure - United States seed lost; idsgendirksf; Encryption Seed Value; key stash file TECHNOTE (TROUBLESHOOTING)
THIS DOCUMENT APPLIES ONLY TO THE FOLLOWING LANGUAGE VERSION(S):
English
PROBLEM(ABSTRACT)
Generating key stash file if the seed value which was used at the time of instance creation has been lost then there is no way to recover this seed value.
RESOLVING THE PROBLEM
There is NO way to recover the seed value used during the instance creation if it has been lost. The only workaround is to create a new instance with a new encryption seed value and then use the db2ldif and ldif2db utilities to export and import data respectively. These utilities can be supplied with the new encryption seed and the salt value of the new instance. Thus the data would be preserved(alongwith the passwords) on this new instance.
Here are the steps to follow:
1. Set up a new instance says "newinst". |
c973a17bd5901015e60f91f00ede0934_1 | $> idsicrt -I newinst -e thisismyencryptionseed -l (/home/newinst) -n
$> idscfgdb -I newinst -w ldap -a newinst -t newinst -l (/home/newinst) -n
$> idscfgsuf -s "o=ibm,c=us" -I newinst -n
$> idsdnpw -u cn=root -p root -I newinst -n
2. Note the encryption seed - "thisismyencryptionseed". Let us call this new_encryptionseed
3. Once this new instance is setup note down the salt value generated by the new server instance by searching for "cn=crypto,cn=localhost".
$> ldapsearch -D <administrator DN> -w <administrator password> -b "cn=crypto,cn=localhost" -s base objectclass=* ibm-slapdCryptoSalt
Let us call this value: new_saltvalue
4. Lets assume that the instance name with the forgotten encryption seed is "oldinst"
5. Use the db2ldif utility on the instance with the forgotten encryptionseed, oldinst with the following options -
$> db2ldif -o outputfile -I oldinst -k new_encryptionseed -t new_saltvalue |
c973a17bd5901015e60f91f00ede0934_2 | 6. Once this step is successfully completed the entire data from "oldinst" would be dumped in outputfile.
7. Use the utilities like ldif2db to re-load all the data into the new server instance.

QUESTION
How do you change the user and/or password for Directory Service Account used by the Content Engine?
ANSWER
The Directory Service user account and password are normally used in two product components: FileNet Enterprise Manager (FEM), and the application server. A coordinated update procedure should be followed when there is a need to change the user account and/or password. This procedure applies to FileNet Content Engine 4.x and above.
*
* Note:
*
* |
11a385c2cd40e3536bfa50b9a55cdd49_1 | If the same user account is also used as the CE Bootstrap user, the corresponding user in the BootstrapConfig.properties needs to change as well. For changing the GCD admin user/password in BootstrapConfig.properties specifically, refer to this documentation:
http://publib.boulder.ibm.com/infocenter/p8docs/v4r5m1/index.jsp?topic=/com.ibm.p8.doc/admin/security/sec_how_change_bootstrap_pwd.htm [http://publib.boulder.ibm.com/infocenter/p8docs/v4r5m1/index.jsp?topic=/com.ibm.p8.doc/admin/security/sec_how_change_bootstrap_pwd.htm]
1. Launch FEM and the application server's administrative console.
a. Login to FEM using the Directory Service account.
b. Login to the application server administrative console with an administrator account.
Important: Do not close above two applications until you have completed step 5 below. |
11a385c2cd40e3536bfa50b9a55cdd49_2 | 2. Make LDAP account changes:
a. Change the password for an existing account on the LDAP server - Using LDAP interface, change the password for the CE Directory Service account.
OR
b. Create a new user account on the LDAP server for the CE Directory Service account.
3. Add new user (if applicable), to FEM
If the bind user is also the CE admin user, then the bind user will need to be added to all the existing objects in the P8 domain. Please read Update object store with new users and groups [http://publib.boulder.ibm.com/infocenter/p8docs/v4r5m1/index.jsp?topic=/com.ibm.p8.doc/admin/security/sec_how_update_os.htm] for instructions |
11a385c2cd40e3536bfa50b9a55cdd49_3 | 4. Change Directory Configuration bind user in FEM
Using FEM (step 1a above), go to Domain properties > Directory Configuration > Select Directory Configuration > click on the Modify button > General Tab:
a. Modify the Directory Service User with new user's full distinguish name (DN)
b. Click on Change password check box > change to a new password > click OK.
At this point you will be presented a dialog box with following message:
“These changes require the application server to be restarted. Please restart the application server to incorporate these changes”
click OK > click OK
Important: Do not restart the application server until you have completed step 5 below.
5. Change the user in the application server's directory configuration
- For Websphere, in the WebSphere Administrative Console, go to Global Security > click on Configure under User Account Repository > Modify Bind Distinguished Name (DN) > Modify Bind Password > click OK and Save changes |
11a385c2cd40e3536bfa50b9a55cdd49_4 | - For WebLogic go to Security Realms > myrealm > Providers > ldap provider and click on "Provider Specific" tab in WebLogic Admin Console. Change "Principal" and "Credential".
- For JBoss go to <JBoss Home>\server\<CE Server>\conf directory and edit "login-config.xml".
Find "FileNet" application-policy and in login module change bindDN/bindCredential.
6. Changing the CE Bootstrap user
For CE 4.5.x and above:
a. In the Configure Bootstrap Properties task, set the Bootstrap Operation property to Modify Existing.
b. Confirm that the Bootstrapped EAR file property contains the path to the bootstrap file you need to edit.
c. Change the Bootstrap user password. Use Configuration Manager's features to save and run the task.
d. Run Configuration Manager's Deploy Application.
For CE 4.0:
Note: This step is needed only if the GCD user name is the same as the Directory Service account. Note that the example below is for a Windows environment. |
11a385c2cd40e3536bfa50b9a55cdd49_5 | - For WebSphere
a. Open command prompt window, go to folder where EAR file reside (it differs depending on CE version). For example, in CE 4.5.1, go to "<CE Home> \ tools \ configure \ profiles \ <profile> \ ear"
b. Backup Engine-ws.ear
c. Execute the command below:
java –jar “c:\program files\FileNet\ContentEngine\lib\BootStrapConfig.jar” –e Engine-ws.ear --username <username> --password <password>
d. Since the Engine-ws.ear file has been deployed in the WebSphere's installedApps path, the Bootstrap file need to be copied to the path manually. Extract the props.jar file from the ear file by utility such as Winzip, copy the props.jar file to theinstalledApps location - “<WebSphere Home>\ AppServer\ profiles \ <profile name> \ InstalledApps \<serverNodecell> \ FileNetEngine.ear \ APP-INF \ lib \"
Note that an alternative to copying the props.jar file is to uninstall and re-install the updated ear file in WebSphere. |
11a385c2cd40e3536bfa50b9a55cdd49_6 | - For WebLogic
a. Open command prompt window, go to folder - "<WebLogic home> \ user_projects \ domains \ <domain> \ servers "
b. Backup FileNetEngine.ear
c. Execute the command below:
java –jar “c:\program files\FileNet\ContentEngine\lib\BootStrapConfig.jar” –e Engine-wl.ear --username <username> --password <password>
- For JBoss
a. Open command prompt window, go to folder - "<JBoss Home> \ server \ <server> \ deploy \"
b. Backup FileNetEngine.ear
c. Execute the command below:
java –jar “c:\program files\FileNet\ContentEngine\lib\BootStrapConfig.jar” –e Engine-jb.ear --username <username> --password <password> |
11a385c2cd40e3536bfa50b9a55cdd49_7 | 7. Remove cached files in the application server
- Close FileNet Enterprise Manager (Step 1a)
- Close Administrative Console (Step 1b)
- Stop the application server
- Remove the cached FileNetEngine directory in the application server.
For example, the default windows path on Websphere 6.0 is
"C:\program files\Websphere\AppServer\profiles\<profile name>\temp\<server node>\
<server>\FileNetEngine"
8. Restart the application server, and login to FEM using the new user and password.
9. Troubleshooting
If CE fails to start due to mistakes in the above procedures, you may not be able to redo the change through these procedures because FEM will fail to run.
In this case, you can do the following: |
11a385c2cd40e3536bfa50b9a55cdd49_8 | - Back out the change made to the GCD database in step 3 by deleting the latest row in the FNGCD table.
- Back out the change made to the application server in step 4 by redoing the procedure with the previous user.
- Back out the change made to the BootstrapConfig.properties file's GCD user by using the backup EAR file
- Restart the application server, and login to FEM using the previous user. |

2b9664521f8d895f07380262c8704a7d_0 | IBM Unable to start Ping Probe by non-root user on AIX - United States Ping probe; non root; start; permissions TECHNOTE (TROUBLESHOOTING)
THIS DOCUMENT APPLIES ONLY TO THE FOLLOWING LANGUAGE VERSION(S):
English
PROBLEM(ABSTRACT)
Ping probe fails to start when the probe is installed and started by non-root user.
SYMPTOM
The following error is seen in the probe's log:
Error: E-P_P-002-038: Could not change euid: Operation not permitted
Error: E-P_P-002-017: IPv4 socket failed: specified action does not have access permission of the file
Error: E-P_P-002-037: This program can only be run by root, or it must be setuid root.
CAUSE
Ping probe needs permissions which allow it to run as root and the LIBPATH setting should be changed.
ENVIRONMENT
AIX |
2b9664521f8d895f07380262c8704a7d_1 | RESOLVING THE PROBLEM
To enable non-root user to start the probe, you need to change the owner to root and permissions to setuid. And AIX ignores the LIBPATH setting when program runs as setuid root, so you also need to put either a copy of the required libraries, or a symbolic link to the required libraries in one of the trusted paths like /lib or /usr/lib.
1. Change the owner to root and permissions to setuid.
e.g
# cd $OMNIHOME/probes/aix5/
# chown root:root nco_p_ping
# chmod +s nco_p_poing
2. Put a symbolic link to the required libraries.
e.g
# cd /usr/lib |
2b9664521f8d895f07380262c8704a7d_2 | # ln -s /opt/IBM/netcool/platform/aix5/lib/libgsk*

# ln -s /opt/IBM/netcool/platform/aix5/lib/libicui18n40.a
# ln -s /opt/IBM/netcool/platform/aix5/lib/libicudata40.a
Note:
The required libraries can be seen by the following command:
# dump -H $NCHOME/omnibus/platform/aix5/nco_p_ping |
2b9664521f8d895f07380262c8704a7d_3 | Note:
If there are newer modules of the required libraries, it's better to create a symbolic link to the newer module.
e.g
Run
# ln -s /opt/IBM/netcool/platform/aix5/lib/libicui18n40.1.a
rather than,
# ln -s /opt/IBM/netcool/platform/aix5/lib/libicui18n40.a
But, please note that it would be better to create the symbolic links again whenever after you apply Fix pack for OMNibus core.

41862f7c54a0fddb543dbf7be76c9a60_0 | IBM SqlException with message "Caught java.io.CharConversionException." and ERRORCODE=-4220 - United States TECHNOTE (TROUBLESHOOTING)
PROBLEM(ABSTRACT)
When an application uses the IBM Data Server Driver for JDBC and SQLJ (also known as the JCC driver) and is connected to a database with code set UTF-8 (code page 1208), it throws an
SqlException with message including "Caught java.io.CharConversionException" and ERRORCODE=-4220 if the data in a character column that it queries contains a sequence of bytes that is not a valid UTF-8 string.
SYMPTOM
An exception is thrown similar to this:
com.ibm.db2.jcc.am.SqlException: [jcc][t4][1065][12306][XXX.XXX.XXX] Caught java.io.CharConversionException. See attached Throwable for details. ERRORCODE=-4220, SQLSTATE=null
[...]
Caused by: java.nio.charset.MalformedInputException: Input length = XXX
[...]
Caused by: sun.io.MalformedInputException
at sun.io.ByteToCharUTF8.convert(ByteToCharUTF8.java:XXX)
[...] |
41862f7c54a0fddb543dbf7be76c9a60_1 | CAUSE
The JCC driver throws the exception when data in a character column that it queries is not a valid string in the database code page.
The invalid data could have been input to the database in the following ways:
* By running an SQL statement which writes byte values to the database. For example: INSERT INTO tab1 VALUES (X'C3')
* By running the IMPORT or LOAD commands for files which contain character data that is not in the code page of the client machine, so the appropriate code page conversion was not done. To make sure that the the appropriate code page conversion is done when running IMPORT or LOAD, specify the code page of the input file by including the "codepage=x" file type modifier (specifying the code page in place of x).
DIAGNOSING THE PROBLEM
You can use the HEX function to find out what are the byte values in a character column.
For example, to find out the byte values in column COL1 in table TAB1, run:
SELECT HEX(col1) FROM tab1 |
41862f7c54a0fddb543dbf7be76c9a60_2 | RESOLVING THE PROBLEM
Update the invalid data with a valid UTF-8 character string.
Alternatively, for JCC driver versions that support it you can set the JCC configuration property db2.jcc.charsetDecoderEncoder=3 so that instead of throwing an exception the JCC driver returns the Unicode REPLACEMENT CHARACTER (U+FFFD) in place of a sequence of bytes that is not a valid UTF-8 string.
The JCC configuration property db2.jcc.charsetDecoderEncoder is supported in versions of the JCC driver that come with DB2 LUW 9.5 Fix Pack 8 and later (APAR IC74896), DB2 LUW 9.7 Fix Pack 5 and later (APAR IC74895), and all DB2 LUW releases from DB2 10.1 onwards. |
41862f7c54a0fddb543dbf7be76c9a60_3 | For example, suppose you have a Java program MyApp.java that executes an SQL query of a database column that contains a sequence of bytes that is not a valid string.
When you run:
java MyApp
it throws an exception. But when you run:
java -Ddb2.jcc.charsetDecoderEncoder=3 MyApp
it returns the string with any invalid sequence of bytes replaced by the Unicode REPLACEMENT CHARACTER.
The Unicode REPLACEMENT CHARACTER often appears like this

aa44f0e81b37ca7d206eb97838ec461a_0 | IBM Leap Second bug in older Linux kernels may affect IBM MQ and WebSphere MQ - United States FLASH (ALERT)
ABSTRACT
Leap seconds are a periodic one-second adjustment of Coordinated Universal Time (UTC) required to keep a system's time of day close to the mean solar time.
A leap second is scheduled for 31 December 2016 at 23h 59m 60s UTC.
In the past, the addition of leap seconds caused some systems running older Linux kernels to fail. IBM MQ and WebSphere MQ queue managers running on these systems generated repeated FDC files showing Probe Id XY348010 or XC272003 from xcsCreateThread, with error code xecP_E_NO_RESOURCE. Other FDCs are also possible. |
aa44f0e81b37ca7d206eb97838ec461a_1 | CONTENT
On 31 December 2016, the Network Time Protocol (NTP) daemon will schedule a leap second [http://en.wikipedia.org/wiki/Leap_second] to occur at midnight, making the final minute of the day 61 seconds long. Prior leap second insertions, including the 30 June 2016 leap second, caused some Linux systems to exhibit unexplained high CPU usage.
IBM MQ and WebSphere MQ use the Native POSIX Thread Library (NPTL) which relies on futuxes ("fast userspace mutexes") for synchronization between threads. Futexes can exhibit high CPU spins after leap seconds on Linux kernel versions 2.6.22 through 3.5-rc7, inclusive, although some Linux distributions shipped patches for kernels in this range:
*
* Leap Second to be added on December 31st 2016
*
*
*
* General information on Leap Second 2016
*
* Fixes and workarounds to avoid issues caused by Leap Second 2015
*
*
*
* Addition of leap second causes spuriously high CPU usage and futex lockups |
aa44f0e81b37ca7d206eb97838ec461a_2 | Contact your Linux vendor to check the status of other distributions, or check the Linux kernel version using "uname -r" and confirm that your system is older than 2.6.22 or running 3.5 or later.
If you encounter this problem, the following workaround may resolve the high CPU usage. As root, run:
* date -s "$(LC_ALL=C date)"

QUESTION
Is DB2 v8, v10.5 compliant to FIPS 140-2 ?.
ANSWER
Is DB2 v10.5 compliant with FIPS 140-2?
Q: Is DB2 vulnerable to the problem described below?
V-58165 DBMS main in the middle attack [https://www.stigviewer.com/stig/database_security_requirements_guide/2015-06-23/finding/V-58165]
"One class of man-in-the-middle, or session hijacking, attack involves the adversary guessing at valid session identifiers based on patterns in identifiers already known. The preferred technique for thwarting guesses at Session IDs is the generation of unique session identifiers using a FIPS 140-2 approved random number generator. However, it is recognized that available DBMS products do not all implement the preferred technique yet may have other protections against session hijacking. Therefore, other techniques are acceptable, provided they are demonstrated to be effective. " |
4c5774389a7413aca3c48842e5f326d8_1 | A: No because DB2 does not use session ids for authentication and thus not vulnerable to the attack described above. DB2 uses encryption modules which are FIPS 140-2 certified.
DB2 v8.x compliancy to FIPS 140-2
DB2 v8.x went out of support in April 2009.
What is ICC?
ICC (IBM Crypto for C) is a set of libraries from Tivoli® for performing encryption. As of DB2® Universal Database™ (DB2 UDB) Version 8 fixpak 7 (equivalent to DB2 UDB Version 8.2), DB2 is using ICC on most platforms.
Customers who need to operate in an environment that is compliant with FIPS 140-2 federal standard should take into account the releases of ICC that are shipped by DB2 on different platforms and the compliance status of those releases with FIPS 140.2.
Following is a list of platforms on which DB2 is using ICC for encryption of data flowing between clients and servers: |

Summary of known problems encountered in ICC 1.2.1/1.2.2:
There are a number of issues with DB2 and the ICC encryption libraries at levels prior to 1.3.9. The known problems are: |
4c5774389a7413aca3c48842e5f326d8_3 | 1. Severe performance problems where processes seem to hang, or take several minutes to run.
2. A bug in ICC code causes it to communicate with the OpenSSL EGD (Entropy Gathering Daemon) which under certain circumstances could hang
3. ICC symbols have not been namespaced and DB2 can end up with symbol collisions with OpenSSL code. This can also happen when multiple versions of ICC are used within the same process.
DB2 Version 8 Fixpak 12 and later incorporates IBM Crypto for C (ICC) version 1.3.9 or 1.4.1 cryptographic module which fixes these problems.

26b405692546ec7b1444f54cb4e27c65_0 | IBM JRules or ODM module fails to access database with StaleConnectionException - United States TECHNOTE (TROUBLESHOOTING)
PROBLEM(ABSTRACT)
JRules and ODM modules such as Rule Execution Server (RES) and Rule Team Server (RTS) / Decision Center (DC) may fail to access their data source with the following type of exception present in the log:
com.ibm.websphere.ce.cm.StaleConnectionException: Io exception: Connection timed out
SYMPTOM
The problem may occur when a JRules or ODM module accesses its data source after a period of database access inactivity. For example: |
26b405692546ec7b1444f54cb4e27c65_1 | * The first user accessing a RTS / DC server that remained idle overnight experiences a failure upon logging and the server log shows an com.ibm.websphere.ce.cm.StaleConnectionException occurred at that time.
* After a RES server has been processing execution requests normally for some time, an attempt to deploy a ruleset update fails and the server log shows an com.ibm.websphere.ce.cm.StaleConnectionException occurred upon an attempt to invalidate a ruleset or to retrieve its definition. |
26b405692546ec7b1444f54cb4e27c65_2 | CAUSE
The underlying network connection for a data source is no longer valid although the data source itself remains considered active from the WebSphere Application Server data source connection pool management perspective. An attempt by a JRules module to try and access its data base through one such data source connection provided by the Application Server may then fail.
The network connection of a data source may become invalid for a number of reasons, one typical example is that a firewall between the Application Server and the Database has a policy to discard network connections that remain idle for some time.
ENVIRONMENT
The exception com.ibm.websphere.ce.cm.StaleConnectionException is specific to WebSphere Application Server environments. But a similar issue can be experienced with Weblogic, see: Rule Execution Server on WebLogic unable to load ruleset after period of inactivity [http://www-01.ibm.com/support/docview.wss?uid=swg21615801] |
26b405692546ec7b1444f54cb4e27c65_3 | RESOLVING THE PROBLEM
Configure the WebSphere Application Server data source connection pool [http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=/com.ibm.websphere.nd.multiplatform.doc/info/ae/ae/udat_conpoolset.html] so as to eliminate occurrences of StaleConnectionException :
* Set the Minimum connections to 0 to avoid situations where a connection is kept in the pool to meet the minimum requirement, even though it may have been idle for longer than Unused timeout
* Set the values for Unused timeout and Reap timeout so that the sum does not exceed any network level idle connection timeout |
