Configuration of this script:
The configuration of this script is read from the following files:
/etc/default/activemq /root/.activemqrc /usr/local/activemq/apache-activemq-5.15.10//bin/env
This script searches for the files in the listed order and reads the first available file.
Modify /usr/local/activemq/apache-activemq-5.15.10//bin/env or create a copy of that file on a suitable location.
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>.
