Increasing Java memory allocation

If you are working with large documents with extensive metadata or key references, you will need to increase the memory allocation for the Java process. You can do this from the command-line prompt for a specific session, or you can increase the value of the ANT_OPTS environmental variable.

To change the value for an specific session, from the command prompt, issue the following command:

Platform	Command
Windows	`set ANT_OPTS=%ANT_OPTS% -Xmx1024M`
Linux/OS X	`export ANT_OPTS=$ANT_OPTS -Xmx1024M`

This increases the JVM memory allocation to 1024 megabytes. The amount of memory which can be allocated is limited by available system memory and the operating system.

To persistently change the value, change the value allocated to the ANT_OPTS environment variable on your system. If you use the startcmd file from the Full Easy Install to set up a toolkit session, edit that file to change the value.
