2.5. JVM Configuration Options.
Abstract
Various settings for the JVM can be configured prior to startup. To do this, edit the
bin/setenv file. The setenv file is used as part of the start-up routine, so for any changes to be picked up they have to be made before JBoss A-MQ is started.
Setting Java Options
Java Options can be set using the
/bin/setenv file. Use this file to set a number of Java Options, such as JAVA_MIN_MEM, JAVA_MAX_MEM, JAVA_PERM_MEM, JAVA_MAX_PERM_MEM. These are the default options. Other Java Options can be set using the EXTRA_JAVA_OPTS variable.
For example, to allocate minimum memory for the JVM use
JAVA_MIN_MEM=512M # Minimum memory for the JVM. To set a Java option other than the defaults, use
EXTRA_JAVA_OPTS="Java option". For example,
EXTRA_JAVA_OPTS="-XX:+UseG1GC".
