Tasks provided by the sysv init script:
restart - stop running instance (if there is one), start new instance
console - start broker in foreground, useful for debugging purposes
status - check if activemq process is running
setup - create the specified configuration file for this init script
(see next usage section)
Configuration of this script:
The configuration of this script can be placed on /etc/default/activemq or $HOME/.activemqrc.
To use additional configurations for running multiple instances on the same operating system
rename or symlink script to a name matching to activemq-instance-<INSTANCENAME>.
This changes the configuration location to /etc/default/activemq-instance-<INSTANCENAME> and
\$HOME/.activemqrc-instance-<INSTANCENAME>. Configuration files in /etc have higher precedence.
