RE: Shutdown Abort Damages Database!

Occasionally, on some of our 8.1.6 dev instances, we get masses of ORA 600's and 7445's that lead to pmon crashing and the database hanging - mainly due to one bug or another. I may be having a senior moment, but I think I have had to do a shutdown abort on at least one of these occasions.

Sometimes, this leaves shared memory and semaphores hanging around. ipcs will show you the resources, but if there are a number of instances on the box, it is difficult to identify the right ones to kill. sysresv (in $ORACLE_HOME/bin) on the other hand will show you the resources for the instance set in your oracle environment. As others have said, you can then use ipcrm to remove the offending resources.

Regards
David Lord
