Operator command cannot be issued: XMCS Subtask is down.
An attempt was made to issue an operator command from within the Application Performance Analyzer started task. The command could not be issued because the Extended MCS Console subtask is not up.
Associated operation is failed.
Review the XMCS SYSOUT for errors, correct any that are found and retry the operation. If the XMCS SYSOUT does not exist then the XMCS subtask has not been started. Make sure that the CONFIG SAMPLE option WAS=YES is specified.
