Your system dump apparently consists of several files.
At the very beginning of the system dump there must be a section that identifies the blockers for each process and looks something like this:
First, check who was blocking the Powercenter process with ospid 89092 (Blocked by…). Then search *all* system dump trace files (*89092*.trc) for the blocker to look at its state objects. Once you now the sid and serial of the blocker, you can position yourself to its state objects with the following search expression: sid: xxx ser: xxx . One of the state objects will be for the cursor that blocked your DDL on MAIN_TAB.
Best regards,
Nenad

Subject: Re: Reading resource busy error system trace
So actually here the session/Alter statement, which failed, is from the informatica power center session only. So do you mean we should search the body of the original trace file from which this trace continued from i.e "u01/app/oracle/diag/rdbms/DB1p/DB11/trace/DB11_ora_89092_8.trc" rather this one. And in that trace the sql statements near the "final blocker" string will be the cause of this error?
Please consider the environment before printing this e-mail.
