RE: startup takes long time on 10gR2.

How many data files are in the database?  It has been a while, but we
ran into a problem where Oracle was checking on every data file and the
startup process was dragging while the check occurred. I apologize, but
I can't seem to find my notes with the details right now.  Maybe this
will help focus where you are looking...

 

This was for HP-UX, so it may not be apples-to-apples for Solaris...

I am assuming that you are on Solaris 8? Is this true? If you truss you
may find that the process starting the database is waiting on "shmat"
call.

        One of our test instances, the startup process is taking more
time.

         

         

        sga is ~2gb.

         

         

        Total System Global Area 2130706432 bytes
        Fixed Size                  2031448 bytes
        Variable Size            1140850856 bytes
        Database Buffers          973078528 bytes
        Redo Buffers               14745600 bytes

         

        especially, the open phase takes long time.(around 10 mins)

        instance allocation and mount phase are quick.

         

         

        Can someone help me, how to start research and reduce the time.

         

        Thanks,

        Raj
