The Upgrade Process › Upgrading Large Data Sets

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 that are used by the upgrade.

You can override the default memory settings for Release 14.2. Create a file named memory.properties and place it in the install/config directory. Set the desired memory values in that file.

Here are the default values that the upgrade uses:

• defaultScriptMaxMem=1024m
• defaultScriptPermGenMem=128m

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

• defaultScriptMaxMem=2560m
• defaultScriptPermGenMem=512m
