Upgrading Large Data Sets

If your CA Clarity PPM upgrade processes a large volume of data, we recommend that you override the default memory settings used by the upgrade.

Upgrade from a version less than Service Pack 12.1.1

You can override the default memory settings provided in the Release 13.1 installer for the Service Pack 12.1.1 portion of the upgrade. Create a file named memory.properties and place it in the install/config directory. Set the desired memory values in that file.

The default values that are used during upgrade are:

Here are some sample settings in the memory.properties file:

All upgrades for large data sets (including upgrades from releases before Service Pack 12.1.1)

The Version 13.0 and Release 13.1 portions of the upgrade apply the memory setting overrides in memory.properties if they are present. To run the Version 13.0 or Release 13.1 upgrade phases with different memory settings, optionally specify the properties for defaultScriptMaxMem, defaultScriptPermGenMem, or both in the release-specific install property files for each release.

To override the Version 13.0 memory defaults:

  1. Locate the Version 13.0 JAR file in the following location: /install-packages/13.0.0/upgrade-repack.13.0.0.7032a.jar.
  2. Extract the contents of the JAR file to a subfolder named: upgrade-repack.13.0.0.7032a.

    Note: The complete path for the subfolder is /install-packages/13.0.0/upgrade-repack.13.0.0.7032a.

  3. Create a file in the subfolder (upgrade-repack.13.0.0.7032a) named release-install.properties.
  4. Add the defaultScriptMaxMem and defaultScriptPermGenMem properties and values to the release-install.properties file.

To override the 13.1 memory defaults:

  1. Locate the Release 13.1 release folder in /install-packages/13.1.0.
  2. Create a file in the 13.1.0 folder named release-install.properties.
  3. Add the defaultScriptMaxMem and defaultScriptPermGenMem properties and values to the release-install.properties file.
