APTJAVAVMMEMORY — Setting the Size of the Embedded Java Virtual Machine
This variable sets the size of the Java Virtual Machine (JVM) embedded in Arbortext Editor. Its value should be an integer, which will be interpreted as the size of the JVM in megabytes.
This environment variable is similar in effect to the ACL set javavmmemory option. The value of APTJAVAVMMEMORY is processed on startup of Arbortext Editor. If its value is specified it is always used, regardless of the setting of any subsequent set javavmmemory commands.
The value of set javavmmemory is analyzed when the command is called, which could be after Arbortext Editor has started the JVM, depending on the installation. set javavmmemory is only respected if APTJAVAVMMEMORY is not set.
The size of the JVM must be determined before it starts — employing APTJAVAVMMEMORY ensures that is always is.
The default maximum size of the of the JVM is 2048 for 64-bit machines, and 256 for 32-bit machines.
