THIS ERROR IS DUE TO INVALID ENTRY IN THE CONTROL FILE:

SOLUTION TO  ORA-00600:

IT IS BETTER TO CREATE A NEW CONTROL FILE.

FIRST CHECK IF CONTROL FILE EXIST OR NOT?

SQL>STARTUP NOMOUNT

SQL> ed a.sql


IF THERE WILL BE A CONTROL FILE THEN IT WILL OPEN. NOW INSIDE CONTROL FILE CHECK THE LOCATION OF:
REDO LOGS
SYSTEM FILE
SYSAUX FILE
UDO FILE
USER FILE

FINALLY DELETE OR BACKUP OLDER CONTROL FILE AND RECREATE NEW ONE USING:
SQL>@ a.sql

CASE 2: IF CONTROL FILE DOESN'T EXIST THEN RECREATE NEW ONE:

SQL>SHUT IMMEDIATE
SQL>STARTUP MOUNT
SQL> alter database backup controlfile to trace
  2  ;

Database altered.

SQL> shutdown abort
ORACLE instance shut down.
SQL> startup nomount
ORACLE instance started.
