$ opmnctl start
LPX-00200: could not convert from encoding UTF-8 to ISO-8859-1
XML parse failed: error 200.
If DCM commands are issued there are also errors
$ dcmctl getstate
Subscription request timed out after 120000 millseconds. Possible causes: OPMN may not be running, you may have an OPMN running in an alternate ORACLE_HOME using duplicate port values, or OPMN may be misconfigured.
$ dcmctl updateConfig
Unable to start the OPMN process within the time-out period.
Try starting the OPMN process using the command line utility "$ORACLE_HOME/OPMN/bin/OPMNctl start". If the OPMN process does not start check the log files in $ORACLE_HOME/OPMN/logs for more information.
Furthermore, there is the potential for any corruption to the "opmn.xml" to be propagated through to the DCM repository (this is done automatically if editing the file via AS Console, or the change can be made if someone issues 'dcmctl updateConfig'). Once this happens, the DCM becomes corrupt and subsequently DCM commands fail as well as OPMN not being able to start.
