Issue/Introduction
How to produce a thread dump that aligns with the elink log in MDM.
Resolution
Any POSIX based Unix/Linux system will support the following command which is constructed to produce a filename with the system name and the exact date/time/millisecond it was performed. This will enable you to align stack traces to elink data:
$ JAVA_HOME/bin/jstack MDM_PID > /tmp/jstack_`uname -n`_`date +%Y-%m-%d_%T,%N`
where MDM_PID is the process ID of MDM. When attaching the thread dumps produced you also provide the current elink logs as the two items become a set.
$ JAVA_HOME/bin/jstack MDM_PID > /tmp/jstack_`uname -n`_`date +%Y-%m-%d_%T,%N`
where MDM_PID is the process ID of MDM. When attaching the thread dumps produced you also provide the current elink logs as the two items become a set.
Additional Information
date command, uname command, Java jstack command
