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> 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
