**********************************************************************

[Pre-Upgrade Recommendations]

**********************************************************************

*****************************************

********* Dictionary Statistics *********

*****************************************

Please gather dictionary statistics 24 hours prior to

upgrading the database.

To gather dictionary statistics execute the following command

while connected as SYSDBA:

EXECUTE dbms_stats.gather_dictionary_stats;

^^^ MANUAL ACTION SUGGESTED ^^^

**************************************************

************* Fixup Summary ************

4 fixup routines generated INFORMATIONAL messages that should be reviewed.

**************** Pre-Upgrade Fixup Script Complete *********************

If still changes are not reflecting Check the preupgrade_fixups.sql script and do the changes manually.

In my case, these changes recommended where I changed below parameters.

– processes” needs to be increased to at least 300

– ALTER SYSTEM SET PROCESSES=300 SCOPE=SPFILE

– EXECUTE dbms_preup.purge_recyclebin_fixup;

– Alter system set job_queue_processes= 100

– EXECUTE dbms_stats.gather_dictionary_stats;

6. Dependencies on Network Utility Packages:

SQL> SELECT * FROM DBA_DEPENDENCIES

WHERE referenced_name IN ('UTL_TCP','UTL_SMTP','UTL_MAIL','UTL_HTTP','UTL_

INADDR','DBMS_LDAP')

AND owner NOT IN ('SYS','PUBLIC','ORDPLUGINS'); 2 3 4

no rows selected

7. Check the timezone version:

SQL> SELECT version FROM v$timezone_file;

VERSION

----------

For 12c, the new timezone is 18. So after the db upgrade is completed, we will upgrade the dst timezone from 14 to 18.

8. Optimizer Statistics

SQL> EXEC DBMS_STATS.GATHER_DICTIONARY_STATS;

PL/SQL procedure successfully completed.

09. Ensure That No Files Need Media Recovery Before Upgrading

SQL> SELECT * FROM v$recover_file;

no rows selected

10. Ensure That No Files Are in Backup Mode before Upgrading

SQL> SELECT * FROM v$backup WHERE status != 'NOT ACTIVE';

no rows selected

11. Resolve Outstanding Distributed Transactions Before Upgrading

SQL> SELECT * FROM dba_2pc_pending;

12. Purge the Database Recycle Bin Before Upgrading :

SQL> PURGE DBA_RECYCLEBIN;

13. Synchronize the Standby Database with the Primary Database When Upgrading

SQL> SELECT SUBSTR(value,INSTR(value,'=',INSTR(UPPER(value),'SERVICE'))+1)

FROM v$parameter

WHERE name LIKE 'log_archive_dest%' AND UPPER(value) LIKE 'SERVICE%'; 2 3

14. Disable cronjob,

Take backup of crontab and comment the same.

15. Disable dbms_schduler jobs:

SQL> set pagesize 2000

SQL> set lines 2000

SQL> set long 99999

SQL> select owner,JOB_NAME,ENABLED,state from dba_scheduler_jobs;

Disable the scheduled jobs by using below command

SQL> execute dbms_scheduler.disable('DRA_REEVALUATE_OPEN_FAILURES);

16. Verify system and sys default tablespace.(Both should be system tablespace)

SQL> SELECT username, default_tablespace

FROM dba_users

WHERE username in ('SYS','SYSTEM'); 2 3

USERNAME DEFAULT_TABLESPACE

------------------------------ ------------------------------

SYSTEM SYSTEM

SYS SYSTEM

17. Check whether database has any externally authenticated SSL users

sql>SELECT name FROM sys.user$

WHERE ext_username IS NOT NULL

AND password = 'GLOBAL';

18. Remove EM repository

---Enterprise Manager Database Control is superseded in 12c by Oracle Enterprise Manager Express . Therefore no repository is needed anymore .

---Run the below script

$emctl stop dbcontrol

SQL> @ ?/rdbms/admin/emremove.sql

19. Review any unnecessary hidden/underscore parameters

SQL> SELECT name, value from SYS.V$PARAMETER WHERE name LIKE '\_%' ESCAPE '\' order by name;

no rows selected

20. With this our precheck completes. Now upgrade phase.

================================================

UPGRADE:

21. stop the listener and shutdown the database.

lsnrctl stop

SQL>shutdown immediate

22.Update the ORACLE_HOME,PATH pointing to 12C Home.

27.Run Catuppst.sql

The catuppst.sql script is run as part of the upgrade process unless the upgrade returns errors during the process.

Check the log file for “BEGIN catuppst.sql” to verify that catuppst.sql ran during the upgrade process. If catuppst.sql has not run, then proceed to run catuppst.sql as shown in this step.

Warning messages are also displayed when running catctl.pl indicating that catuppst.sql was not run during the upgrade.

SQL>@catuppst.sql

Now upgrade is completed. Now Proceed with POST CHECK.

27. UPGRADE DST TIME ZONE:

1 row selected.

Once DST upgrade completes, Do the below post checks.

1. SQL> @/u00/app/oracle/cfgtoollogs/UPGRD/preupgrade/postupgrade_fixups.sql;

2. Change the ORACLE_HOME to 12c in listener.ora file.

3. Uncomment the crontab

4.Enable the jobs in dba_scheduler_jobs which we disabled before the upgrade.

5. run utluiobj.sql from $ORACLE_HOME/rdbms/admin/ to identify/compare any new invalid objects due to the upgrade.

If the upgraded database is the only database on the current system, then you need to create a Container Database (CDB) first

Once the CDB is created you can proceed with the next step.

• Create a container database
