The pmon-restart service, through a call to respawn_process,
increments that process's restarts counter but does not clear
that counter after a successful restart.
So, each pmon-restart mistakenly contributes to that process's
failure count. This has the effect of pre-loading that process's
restart counter by one for every pmon-restart of that process.
The effect is best described by example.
Say a process is pmon-restart'ed 4 times during one day which
increments that process's restart counter to 4. So assuming its
conf file specifies its threshold is 3 ; its already exceeded
its threshold. Then, even days later that process experiences
a real failure pmon will immediate take the severity action
because the failure threshold had already been exceeded.
This update ensures a process's restart counter is cleared
after successful pmon-restart operation ; in the process pid
registration phase of recovery.
Test Plan:
PASS: Verify pmon-restart continues to work.
PASS: Verify proper thresholding of failed process following
many pmon-restart operations.
PEND: Verify pmon-restart and process failure automated test script
against this update. 5 loops, all processes.
