Hi Guys,
We have this chronic issue of "db hang" on our production database.
It all starts with MMNL running and performing "db file sequential read", which in turn,makes background jobs, check db to hang.
And, within no time, a situation arrives where our production system can be considered dead.
Workaround:
The moment we kill MMNL process from O.S level, things get back to normal.
I am trying to find a permanent fix to this problem but falling short of ideas.
Please suggest on how to troubleshoot.
Thanks and Regards,
Ankit Mishra
