CSS Import or Export Operation Fails with Error: 'java.lang.OutOfMemoryError: Java heap space'

 Modified 24-MAY-2010 

Applies to:

Hyperion Financial Management - Version: 9.3.0.0.00 to 11.1.1.3.00 - Release: 9.3 to 11.1
Microsoft Windows (32-bit)

Symptoms

CSS import or export operation fails with error message similar to the one below: 
'java.lang.OutOfMemoryError: Java heap space'

Exception in thread "Thread-3" java.lang.OutOfMemoryError: Javaheap space.

Cause

The number of provisioning records to be imported or exported is too high for Java memory heap allocated for the operation.

Solution

Increase Java memory heap size for CSS import or export operations:

  1. Edit the CSSExport.bat or CSSImport.bat files for export or import of provisioning data.
  2. Increase Java memory heap size using arguments: -Xms512 -Xmx512. The modified line in the file should look like this: 
    "%JAVA_HOME%\bin\java" -Xms512m -Xmx512m -cp %CLASSPATH% com.hyperion.css.exchange.CommandUtility -ef %1

  3. Save the file and try to import or export provisioning data again.
