Operating Systems AIX JVM Setting Post 302240926 by cbkihong on Saturday 27th of September 2008 05:01:36 AM

My understanding is that there is a restriction to the amount of memory the JVM can use. So even though you have 16GB, you may not be able to use too much of it with a single VM instance.

For your information:

Garbage Collection Ergonomics

You can confirm by running JConsole on your JVM process and check the various memory settings (e.g. heap max and current heap utilizations).

NAME
wbemconfig - convert a JavaSpaces datastore to the newer Reliable Log datastore format SYNOPSIS
/usr/sadm/lib/wbem/wbemconfig convert DESCRIPTION
A Reliable Log directory is created that contains the converted data. This directory is named /var/sadm/wbem/logr. The convert argument is the only supported option of this command. You should only run this command after stopping WBEM (CIM Object Man- ager) with the init.wbem stop command. Otherwise your data may be corrupted. This command successfully converts any proprietary custom MOFs you have created in the datastore, but not any CIM or Solaris MOFs you have modified. These will be destroyed. To recompile any modified CIM or Solaris MOFs into the new datastore, run the mofcomp command on the MOF files containing the class definitions. Because the wbemconfig convert command invokes the JVM (Java Virtual Machine) to perform conversion of the JavaSpaces datastore, you must be running the same version of the JVM as when the original JavaSpaces storage was created. After the wbemconfig convert command is com- pleted, you can change to any version of the JVM you want. To see what version of the JVM you are running, issue the java -version command. OPTIONS
The following options are supported: convert Convert a JavaSpaces datastore to the newer Reliable Log datastore format. ATTRIBUTES
