CC_JVM_OPTIONS

Set this environment variable to specify the Java™ virtual machine arguments that are used when a job is run.

When this variable is specified, it takes precedence over the value of the default Java virtual machine arguments for the Java-based connectors. For example, if you set CC_JVM_OPTIONS as -Xmx512M, the maximum heap size is set to 512 MB when Java virtual machine instances for the connector are created.
