Dear All,
Oracle Version:
Operating System: Windows Server 2003

i made a mistake by changing the parametrer COMPATIBLE='9.2.0' in oracle version

after restarting DB SERVER, i m getting the following error
SQL> conn sys/gateway@testdb as sysdba

SQL> conn scott/tiger@testdb
ORA-01033: ORACLE initialization or shutdown in progress

Warning: You are no longer connected to ORACLE.

SQL> alter database open
2 ;
alter database open
ERROR at line 1:
ORA-01507: database not mounted

SQL> alter database mount;
alter database mount
ERROR at line 1:
ORA-00201: controlfile version incompatible with ORACLE version

i think i have to recreate spfile by first starting the DB by using pfile

Can anybody give me some suggestions for that?

thanx in advance

I was expecting this error from you after seeing a post in Streams section.
