ORA-00600: internal error code, arguments: [2141]

Problem Description
While starting up or shutting down the database it fails with oracle error message ORA-00600: with the first argument 2141. A sample message from my screen,
SQL> shutdown immediate;
ORA-00600: internal error code, arguments: [2141], [4192191924], [0], [], [], [], [], []

Cause of the Problem
The problem happened due to incorrect control files. If you have different versions of controlfile or if you have wrong controlfile pointed inside spfile/pfile then while startup the database above bug will fire. Similarly after starting up the database if you replace your controlfile by wrong one then while shutting down the database above bug will fire.

Solution of the Problem
The solution of this problem is to correct control_files parameter settings within spfile/pfile whenever you start up the database. Below procedures will help you.

1) Whenever you start up the database make sure whether you start the database by pfile or spfile and also be sure about their location.

2) If you are not sure which file is used then issue "startup nomount" command after connecting as sqlplus / as sysdba to the database.

3) If you start your database with spfile then issuing "show parameter spfile" will locate the location of your spfile location. So simply create a pfile by issuing "create pfile='new_pfile' from spfile" will give you pfile and you can work with that.

4) Whether you start your database with spfile or pfile if you issue "show parameter control_files" it will list the control_files that is denoted by the control_files initialization parameter inside your spfile/pfile (by which one you started your database).

5) Note those locations and check whether the locations are correct. If those are not correct and if you use spfile you can change the locations by,
SQL> alter system set control_files='/oradata1/arju/newcontrol01.ctl', '/oradata1/arju/newcontrol02.ctl' scope=spfile;
and then "startup force". If you use pfile then you need to change manually after opening the pfile with a text editor.

6)If you get error still then check one by one control files as described in the post http://arjudba.blogspot.com/2008/04/ora-00214-controlfile-version.html

If you get this error message while you shutting down your database, then do a shutdown abort and follow the same steps as it is written for startup the database procedures.
