ERROR at line 2:

ORA-00942: table or view does not exist

This  error is related to timezone file  which must be version 4 for Oracle version 11g.If timezone is not version 4 than patch needs to be applied.

Query to check timezone file  is:

SQL> select * from v$timezone_file;

FILENAME        VERSION

———— ———-

timezlrg.dat          4

SQL> select * from v$timezone_file;

FILENAME        VERSION

———— ———-

timezlrg.dat          4

So I had correct version.I remember applying patch before upgrade.I got lucky because patch existed for version 10.2.0.3.

If there is no patch for your Oracle versions than patch can be download for similar version and  applied manually.

Instructions are below:

1.  Download the identified patch.

2. Unzip the patch, and locate the 2 files timezone.dat and timezlrg.dat in the “files/oracore/zoneinfo” directory of the uncompressed patch (or from the relevant .jar file of a   patchset). If there is also a readme.txt in this location then make a note of this as well.

3. Backup your existing files in $ORACLE_HOME/oracore/zoneinfo – THIS CAN BE VITAL, DO NOT SKIP.

Note:

Before going on with step 4, make sure the current files are not in use.

On Windows the files will simply refuse to be removed when the are in use.

On Unix replacing the files whilst they are in use can cause the files to become corrupt. Use the fuser command before replacing the files to make sure they are not in use.

4. Copy the 2 .dat files and possibly the readme.txt file that were found in step 2 into the $ORACLE_HOME/oracore/zoneinfo directory.

5. Restart the database (in case of installation on a database), or restart the client applications (in case of client install). Note that the database did not need to be down before the time zone files were applied, but it does need to be restarted afterwards.
