Configuring InfoSphere Data Architect (IDA) or/and Rational Software Architect (RSA) for use with the IBM Industry Models

Troubleshooting


Problem

This document provides recommendations on how to configure your IDA or/and RSA for use with the IBM Industry Models.

Resolving The Problem

Eclipse maximum Java heap size

By default the maximum Java heap size of RSA and IDA is 1Gb.

To improve the performance of RSA and IDA when using our models this needs to be increased:

  • in 32-bit IDA, set the maximum Java heap size to 1536Mb
  • in 32-bit RSA, set the maximum Java heap size to 1280Mb
  • in 64-bit IDA or RSA, the maximum Java heap size is limited only by the amount of physical RAM on your computer. For instance, on a computer with 8Gb+ RAM you could set the maximum Java heap size to 4096Mb

To set the maximum Java heap size:
  • close RSA/IDA
  • locate the eclipse.ini file, which is in the RSA/IDA installation folder (e.g. C:\IBM\RSA_64)
  • open eclipse.ini in a text editor (if RSA/IDA is installed in the default Program Files folder run the text editor as Administrator)
  • change the -Xmx option
  • save eclipse.ini
  • restart RSA/IDA

To show the Java heap status in RSA/IDA:

  • Choose the Window > Preferences menu item:
  • Select the General preference page
  • Enable the Show heap status option
  • Click OK

The Java heap status is now displayed in the bottom right of the RSA/IDA window.

You can request a Garbage Collection by clicking the bin icon - this can improve the performance of RSA/IDA after a memory intensive operation has been performed.


Local History

To help prevent loss of work due to a model file being accidentally deleted or becoming corrupted due to an RSA/IDA crash, you can configure the Local History preferences to maintain a local history of large model files:

  • Choose the Window > Preferences menu item:
  • Select the General > Workspace > Local History preference page
  • Enable the Limit history size option
  • Set the Days to keep files option, e.g 7
  • Set the Maximum entries per file option, e.g. to 5
  • Set the Maximum file size (MB), e.g. to 50
  • Click OK

For more information, select the Help > Help Contents menu in RSA/IDA and navigate to Eclipse documentation > Eclipse platform > Tasks > Working with local history.

Note: Configuring the Local History preferences to maintain local history for large files can consume a lot of disk space on your machine.


Pluglet Development

Pluglets are small Java applications that are used to make minor extensions to the RSA/IDA workbench in a simple and straightforward way.

When Pluglet Development is enabled you can run existing Industry Models pluglets. See Extending the modeling environment using pluglets for more information on pluglets.

Before pluglet development can be enabled, the Pluglet Support feature must be installed to RSA/IDA.

If you did not choose to install the Pluglet feature when installing RSA or IDA, you can install it by modifying RSA/IDA in Installation Manager:

  • close RSA/IDA
  • run IBM Installation Manager
  • click Modify
  • choose the Package Group that RSA/IDA is installed to and click Next
  • in the Modify Packages page enable the Pluglet Support feature and click Next
  • click Modify

To enable pluglet development in RSA/IDA:
  • Choose the Window > Preferences menu item:
  • Select General > Capabilities then click Advanced...

  • Enable Eclipse Developer > Pluglet Development capability
  • Click OK

  • Click OK
