I agree with the other members who responded that probably it's just a
case of SMON having to do a lot of work - and not using old-school
tablespace types. There is one other possibility perhaps: The ugly, old
bug w.r.t. memory leaking and Shutdown immediate just hanging. I think
the usual workaround still works:
event="10262 trace name context forever, level 0"

Hello all:
We have Oracle 9.2.0.5 database ( single Note RAC ). There were some heavy batch jobs running which cuased the db hang ( only sys connection was working ).
We tried to bring down the database after cleaning all sessions. It did not go down with SHUTDOWN IMMEDIATE. We had to abort it. I tried to bring down the DB three times with SHUTDOWN IMMEDIATE it never went down.
SMON was trying to cleanup the used extents ( Metalink Note - *1076161.6* ) as we could see in the alert log file - *Waiting for smon to disable tx recovery*.
SQL> select count(block#) from fet$;
COUNT(BLOCK#)
-------------
38
fet$ - free extents
SQL> select count(block#) from uet$;
COUNT(BLOCK#)
-------------
*52905*
uet$ - used extents
We can share the alert log and system level 10 trace files if anyone wants. These traces were generated when db hung.
Appreciate your help.
Thanks,
