But if the broker starts before the ALM service starts, obtaining a licence from the ALM server is impossible... |
Problem Statement: When MIMI starts in UNIX, you get the following error: "Error opening message file." | Solution: Confirm that the MIMIHOME environment variable is to the correct path. It should be the directory where MIMI is installed, for example, /MIMI. If MIMIHOME is set correctly, then the MIMITEXT.DATA file may be missing. (This is the file that contains all of your error messages.) Search for the file in your $MIM... |
Problem Statement: Increasing the maxcount of a set results in "Case corrupted, not enough memory - reload case file." | Solution: A customer recently tried to increase the MAXCOUNT of a set to 100000 and received in the message bar the following error message: "Case corrupted, not enough memory - reload case file".
This message occurs when MIMI can not allocate enough memory to hold the existing set as well as the new set it is trying t... |
Problem Statement: Aspen SCM crashes immediately at startup, either when you try to open a case file, or when you simply open Aspen SCM from the Windows Start menu. | Solution: The cause of the crash may be that the FLEXlm License Management Selector utility is not correctly configured.
You run this utility from the Windows Start menu:
Start | Programs | AspenTech | Common Utilities | FLEXlm License Management Selector
Examples of incorrect configuration can be:
- You are pointi... |
Problem Statement: Can I open or close an Activity Editor or the Planning Board from within a rule or macro? Is there a way to define an after-procedure for an Activity Editor? | Solution: The MIMI command to be used is S MODIFY, which is effective when the Planning Board is visible. This command, depending on the argument you supply to it, can either display the Activity Editor, if not already visible, or close it removing it from view.
The syntax in the first case is:
S MODI[FY] ind

Problem Statement: Why is $BATCH failing when it runs in batch mode but not if it is run from the command line?
$BATCH probably expects certain set indexes to be established. When you load a case interactively, $LOAD$ runs and sets these indexes. Three possibilities are LANGUAGE, SCRNRES, and RBTROLES. There could be o... | Solution: ? Add the administrative parts of $LOAD$ to the beginning of $BATCH.
- Include everything prior to "CAP specific functions" and "application specific functions".

Problem Statement: How do I take data from MIMI and place it into a text file? | Solution: There are two ways to do this:
If the data is not very large, you can cut the raw data and paste it into a text file. After that, you will have to modify the text file itself to a fixed length or a comma delimited file, depending on the preference of the user.
If the data is a large amount, you can use the w... |
Problem Statement: I have used underscores in the names of my MIMI dialog objects before without any problems. However, sometimes my dialogs do not appear, or just the title bar appears when I use underscores in object names. What is causing this and how can I fix it? | Solution: There is nothing wrong in using underscores for object names in MIMI dialogs, as long as you are careful not to use extensions on resources where it is not intended.
For example, the name "PB_APPLY" is okay because "PB" is not a resource type - "PUSHBUTTON" is. However, when you use "LABEL_SOMETHING" or "TEXT... |
Problem Statement: SELECT (syntax for selecting set data) runs too slow in my MIMI rule. | Solution: If you have a rule containing SELECT statements and you think it is taking too much time to run (for example you can see that through the MARK TIME command), then you may want to check the MAXCOUNT of the CHOOSE set.
If it is unnecessarily big, then your SELECT will run at a considerably lower speed if you de... |
Problem Statement: MIMI splash screen won't disappear when loading MIMI 6.x and higher. | Solution: This problem is a result of using the COMBINED option in the FlexLM License Management Selector. To get around this, use one of the following 2 work arounds.

Click on Start --> Programs --> AspenTech --> Common Utilities --> FlexLM License Management Selector.
Click on the first radio bu... |
Problem Statement: Unable to open or create scratch file CMP 1216.scr when running CMPRCASE utility. | Solution: By default, the CMPRCASE utility writes out its scratch file to the c:\ drive even if the utility does not reside on that drive. In the case where users are locked out of the c:\ drive for security purposes, CMPRCASE will still try to create a scratch file on the c:\ drive.
It is possible to redirect the CMPR... |

To avoid this problem, please verify the two following items:
Do not use another set to display the list of the inv... |
Problem Statement: Why should you check the flag "Force installation of all core components" in MIMI installation? | Solution: All Aspen products install common third party tools as core components. This allows them to be shared among the products and tracked properly by the master installer. The idea of having check box "Force installation of all core components" in MIMI installation is to save installation time. For instance if a c... |
Problem Statement: How can a user have multiple languages selected and not face the Planning Board issue as described in Tech Tip 105030 ? | Solution: In a previous Tech Tip (105030), we described the problem of the multiple languages selection that causes the Planning Board to be empty after installing MIMI on Windows 2000 and how to resolve the problem by deselecting the languages from the Registry Settings or the Regional Options. However, users who indi... |
Problem Statement: Does MIMI add to Win.ini, System.ini, Autoexec.bat or Config.sys files? | Solution: MIMI does not add to Win.ini, System.ini, Autoexec.bat or Config.sys files. But it does install .DLL's to the WINNT\SYSTEM32 folder.

Problem Statement: When I enter PROCNAME on the command line, I get the error message "PROCNAME has not been defined." | Solution: The problem is due to one of the causes described below. In most of the cases you need to re-install MIMI to solve it.
First of all you have to be sure that you chose the "Server Install" and not the "Standard Install" option when installing MIMI. Otherwise, you will not have Distributed MIMI functionalities,... |
Problem Statement: My company is moving to a Windows XP managed environment. Does AspenTech provide an msi file for the installation of MIMI in such an environment? | Solution: AspenTech does not currently support the msi format at this time.

AspenTech has a development project to eventually migrate all AspenTech installations to the msi format, but have not determined when or how long it will ta... |
Problem Statement: If MIMI doesn't start and returns a memory exception error from Windows, you may need to manually install the NobleNet Portmapper Utility. This condition is a chain reaction when the broker is not running because the NobleNet Portmapper is not installed properly.
Typically, this utility may need to b... | Solution: Before you begin this procedure, we assume that MIMI has already been installed and the MIMI Request Broker and the Noble Net Portmapper are not running.
Using Windows Explorer, browse to the "C:\Program Files\Common Files\AspenTech Shared\Portmapper" directory.
Execute the portint.exe program.
Select the "In... |

Problem Statement: I get the error message "unable to obtain license" when I start MIMI. | Solution: Potential causes for this error are:
This error message is indicative of MIMI unable to lease a license from the Aspen License Manager server. This usually happens when there are more MIMI users trying to use MIMI than there are licenses.
Also, this error can happen if a user downloads only one license for u... |
Problem Statement: "Error in I2C Function" while running CAS2DAT. | Solution: The I2C error can be caused by one of several reasons:
If you are trying to run a cas2dat on a file that is already in a DATA format, you will get this error.

Problem Statement: I am getting the error message "SOURCE1 set not found" when performing a set subtraction such as TMP = TMP - CHOSEN. Do you know what causes it? | Solution: Any command that modifies the size of a set or a table will create "holes" in memory. This means that while the memory used may be well within the range available, there may not be enough contiguous memory to create the table. This will result in the application running out of memory.
Saving and reloading the... |
Problem Statement: What is the difference between the Application Client and Light Client? | Solution: Application Client: The MIMI case resides on a workstation or server. When the case is opened, all processing will be done on the workstation, utilizing the workstation CPU, memory, and other resources.
