PMON—the Process Monitor
The Process Monitor is responsible for performing the following operations:
Process recovery when a user process fails, including cache cleanup and the freeing of resources the process was using
Rollback of uncommitted transactions
Release of locks held by failed or terminated processes
Restart of failed dispatcher and shared server processes
The PMON process wakes up on a regular basis to check whether any of these operations are required. In addition, other background processes can wake up PMON if they require one of these services.
