Both INITIAL_MEMORY and MAX_MEMORY allow configuration of memory usage for the Java Virtual Machine (JVM).

Symantec recommends that the NetBackup-Java Administration Console, the Java Windows Administration Console, or the NetBackup, Archive, and Restore user interface run on a system that contains at least 1 gigabyte of physical memory. Make sure that 256 megabytes of memory are available to the application.

INITIAL_MEMORY specifies how much memory is allocated for the heap when the JVM starts. The value probably does not require changing. The default is sufficient for quickest initialization of jnbSA, the Java Windows Administration Console, or jbpSA on a system with the recommended amount of memory.

On UNIX systems, the initial memory allocation can also be specified as part of the jnbSA or jbpSA command. For example:

jnbSA -ms 36M

Default = 36M (megabytes).

MAX_MEMORY specifies the maximum heap size that the JVM uses for dynamically allocated objects and arrays. If the amount of data is large, consider specifying the maximum heap size. For example, a large number of jobs in the Activity Monitor.

On UNIX systems, the maximum memory allocation can also be specified as part of the jnbSA or jbpSA command. For example:

jnbSA -mx 512M

Default = 256M (megabytes).
