Issue/Introduction

ActiveMQ will not start and nothing is shown in the startup messages or logs

Environment

Release : 20.2

Component : IM Reporting / Admin / Configuration

Resolution

To potentially reveal a fault happening before the process is fully started up, you can:

1. In /opt/IMDataCollector/scripts/activemq, add these lines after the ACTIVEMQ_OPTS=.... line: (about line 26):


ACTIVEMQ_OUT=/tmp/activemq.out
export ACTIVEMQ_OUT


2. Start ActiveMQ, wait for it to die, then grab /tmp/activemq.out.  This will grab the items printed to stdout/stderr that we normally send to /dev/null during startup.

This should be disabled as soon as the needed information is obtained
