Hi Gurus,

Operating system win2000 advanced server
Oracle version 8.1.7

Initially our database was oracle standard edition, since we needed partitioning option we have added the partioning option with oracle installer.
Now we are unable to start the database.
When I type svrmgrl i am geting ORA-03113 end of file communication error.
And CORE file is generated with following massages

can someone give me an idea whats happening.

Oracle8i Release 8.1.7.4.1 - Production

Excp. Code: 0xc0000005 Excp. Type: ACCESS_VIO Flags: 0x00000000

Thanks in advance
