I have opened a TAR with Oracle and am waiting a resolution. In the meantime, I am wondering if anybody else has any ideas while I wait.
Specifics: IBM AIX 4.3 Rdms 8.1.7.3 Database ~75g OLTP database with approximately 500 dedicated connections and 500 shared connections with Oracle's MTS. Problem: The database hangs, and no user is able to connect to the instance, except locally through srvmgrl. Even within svrmgrl, we are unable to select anything from the database without the query hanging. However, we can abort the instance (shutdown abort) and start it up again just fine. This has happened on 4-22, 4-29 & 4-30 in the early afternoon. Usually, this is also our peak busy rate for the week. We are executing MTS for 4 applications, all other applications connect through dedicated server. The alert log contains a message unable to start a shared server process. This week it was #41 and last week it was #25. Normally, we do not exceed 5 shared servers. Another thing I noticed is that there is no time allocated to any of the newly created shared servers. It is as if, it can not process any work through existing shared servers and decides to allocate another one, until finally it freezes. I am not sure if this is a MTS problem because I would suspect that I should be able to establish a dedicated server connection. And I can not. I think that this is just a symptom of the underlying problem. It would appear to me that we are running out of a resource, however our sysadms do not see any resource problems. Does anybody have any ideas how to debug this?
