Hi Pando,

I tried the same now.

SQL> startup mount;
ORACLE instance started.

Total System Global Area 135338868 bytes
Fixed Size 453492 bytes
Variable Size 109051904 bytes
Database Buffers 25165824 bytes
Redo Buffers 667648 bytes
Database mounted.

SQL> recover automatic database;
Media recovery complete.

SQL> alter database open;
alter database open

ERROR at line 1:
ORA-01092: ORACLE instance terminated. Disconnection forced

Please help me to come out from this problem. I highly appreciate your time.
