Available Memory

Diagnose and troubleshoot memory shortages.

java.lang.OutOfMemoryError

When you are running out of memory, either the Replication Agent drops out of Replicating state or the entire Replication Agent server stops executing.

To support adjusting the amount of memory available to the JRE, all of the executable scripts (or batch files) in the Replication Agent bin directory refer to an environment variable named RA_JAVA_MAX_MEM. All Replication Agent instance RUN scripts also reference the RA_JAVA_MAX_MEM environment variable.

On HP-UX, if the RASD runs out of memory, increase the size of maxdsiz_64bit from 2 GB (default) to 4 GB. For more information, see HP documentation.

• Default Heap Size
  Replication Agent does not set the RA_JAVA_MAX_MEM environment variable in the executable or RUN scripts, enabling the JVM to use the default maximum heap size.
• Default Maximum Memory Setting
  The default maximum memory can be set in three ways.
