Out Of Memory Errors
Processing large dump files
Processing large dump files using Memory Analyzer may sometimes fail with a java.lang.OutOfMemoryError. The default maximum Java heap size when running ISA 4.1 is 256Mb. We recommend running Memory Analyzer with at least 512Mb.
To set the maximum heap size you can add a property value to the rcpinstall.properties file.
Updating the rcpinstall.properties file
The rcpinstall.properties file resides in the following workspace location:
<home drive><home path>\IBM\ISAv41\.config\rcpinstall.properties
Add or update the value for vmarg.Xmx property. For example:
You will need to restart ISA for the change to take effect.
