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"

        Subject: startup takes long time on 10gR2.

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