Upgrade From a Version Less Than v12.1.1

You can override the default memory settings provided in the CA Clarity PPM v13.0 installer for the v12.1.1 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 used during upgrade are:

• defaultScriptMaxMem=1024m
• defaultScriptPermGenMem=128m

Sample settings in the memory.properties file:

• defaultScriptMaxMem=2560m
• defaultScriptPermGenMem=512m
