Dear all,

I've installed Oracle 9201 on a Windows 2000 Advanced Server. The target installation folder is D:\Oracle, all data files are stored in D:\Oracle\oradata. Then I tried to upgrade this installatiion to 9206. Before installing PatchSet 9206, I've stopped all Oracle NT services, then I've copied the whole directory tree of D:\Oracle to another place. After succeeded installing the patch set and upgrading the database, the I want to restore the test environment to the original status. These steps are

1.Stop all Oracle related NT services, succeeded
2.Restore all backed up files to their original place, succeeded
3.Start Oracle database instance service, succeeded
4.Start Oracle listener service, succeeded
5.Use sql plus connect to the database, FAILED

SQL> conn user/password@db_server
ERROR:
ORA-01033: ORACLE initialization or shutdown in progress

6.Use sql plus connect to the database as SYSDBA, succeeded
7.Use sql plus to SHUTDOWN the database, succeeded
8.Use sql plus to STARTUP the database, FAILED

SQL> startup
ORACLE instance started.

ORA-00600: internal error code, arguments: [kcratr1_lostwrt], [], [], [], [], [], [], []

What's the problem? Did I miss some necessary steps to backup the system before installing the patch set? What can I do to prevent this error when I restore the database if the upgrading process fails? Thanks for any help.

Regards,
George
