Hi, I have taken the backup of a database and when i restore the backup and started the Oracle database, the database is mounted. Then when i issue the "alter database open resetlogs" command, i got the below error. ERROR at line 1: ORA-01194: file 1 needs more recovery to be consistent ORA-01110: data file 1: '/data/oracle/NYP15S1D/data03/SYSTEM_01.dbf' So i added the parameter "_allow_resetlogs_corruption=TRUE" in "init.ORA" file to force open the database but the Oracle instance terminated with following message. In the alert log the following error is there: ksedmp: internal or fatal error ORA-00600: internal error code, arguments: , , , , , , ,  How can i resolve the issue? Please note: the database is Oracle 9i, installed in UNIX AIX OS. Thanks, Regards, Venkatesh.
