Re: Database down

Just to follow up. I have the database backup. I am afraid however, that the problem is still floating around.

Briefly, here is what occured:

I restarted Oracle because our application was unable to connect. I could connect through svrmgrl, but a 'select sysdate from dual' just hung. So I brought the database down, and recieved the memory segment error.

So we were having problems while the database was up. Here is a trace file dump that may be linked to the problem:

  PMON unable to acquire latch 80002060 modify parameter values     possible holder pid = 58 ospid=29937

We added a third application server last week. Could that somehow be the source of these problems? This application has been running problem free for over 100 days.

Thanks for your input

Jeff

Hi Jeff,

  1. the previous killed instance that still holds a shared memory segment ?
  2. unappropriatedly large parameters of shared_pool and/or db_block_buffers ?

Regards,
Ed
