Environment

DX NetOps CAPM 20.2.x

Cause

Trying to run activemq gives the following;

[email protected]:/opt/IMDataAggregator/broker/apache-activemq-5.15.8/# cat activemq.out

Error: Password file read access must be restricted: /opt/IMDataAggregator/broker/apache-activemq-5.15.8/conf/jmx.password

sun.management.AgentConfigurationError

        at sun.management.jmxremote.ConnectorBootstrap.checkPasswordFile(ConnectorBootstrap.java:577)

        at sun.management.jmxremote.ConnectorBootstrap.startRemoteConnectorServer(ConnectorBootstrap.java:426)

        at sun.management.Agent.startAgent(Agent.java:262)

        at sun.management.Agent.startAgent(Agent.java:452)

Resolution

Change the permissions on the jmx.password file so that only the root user has any form of access;

chmod 600 <IMDataAggregator_DIR>/broker/apache-activemq-5.15.8/conf/jmx.password

This will allow the activemq to start normally and sync to CAPC.
