The tool acts as a "window" into the database shared memory. DBAs typically use it for the following critical tasks:
: Identify which users are holding specific record locks and view the "Lock Table" flags to resolve transaction bottlenecks.
PROMON is typically launched from the command line of the server hosting the database. : Execute promon (e.g., promon mfgsys ).
PROMON is a battle-tested tool that transforms how mainframe teams monitor and control IMS/CICS systems. By providing real-time visibility and automation, it reduces downtime, speeds troubleshooting, and frees up staff for higher-value work. If your organization runs mission-critical transactions on z/OS, PROMON is worth exploring—even as you plan for hybrid or modernized operations.
: Identify record locks that may be causing application "hangs." The PROMON command can display which user holds a lock and which users are waiting for it.
While its strength is real-time, PROMON can log data for trend analysis—peak usage times, average transaction loads, and resource consumption patterns.
