Ramesh B: oracle database stand alone Upgradation from 11.2.0.4 to 12.1.0.2

Upgradation from 11.2.0.4 to 12.1.0.2

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

First we need to download the 12.1.0.2 RDBMS software from metalink and install in seperate home.

Run the new preupgrade check script preupgrd.sql, in 11.2.0.4 environment – it will generate 3 files:

SQL> @/u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/preupgrd.sql

====>> ERRORS FOUND for ORCL <<====

The following are *** ERROR LEVEL CONDITIONS *** that must be addressed

prior to attempting your upgrade.

Failure to do so will result in a failed upgrade.

You MUST resolve the above errors prior to upgrade

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

====>> PRE-UPGRADE RESULTS for ORCL <<====

ACTIONS REQUIRED:

1. Review results of the pre-upgrade checks:

/u01/app/oracle/cfgtoollogs/orcl/preupgrade/preupgrade.log

2. Execute in the SOURCE environment BEFORE upgrade:

/u01/app/oracle/cfgtoollogs/orcl/preupgrade/preupgrade_fixups.sql

3. Execute in the NEW environment AFTER upgrade:

/u01/app/oracle/cfgtoollogs/orcl/preupgrade/postupgrade_fixups.sql

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

WARNING: --> Process Count may be too low

Database has a maximum process count of 150 which is lower than the

default value of 300 for this release.

You should update your processes value prior to the upgrade

to a value of at least 300.

For example:

ALTER SYSTEM SET PROCESSES=300 SCOPE=SPFILE

or update your init.ora file.

WARNING: --> Enterprise Manager Database Control repository found in the database

In Oracle Database 12c, Database Control is removed during

the upgrade. To save time during the Upgrade, this action

can be done prior to upgrading using the following steps after

copying rdbms/admin/emremove.sql from the new Oracle home

- Stop EM Database Control:

$> emctl stop dbconsole

- Connect to the Database using the SYS account AS SYSDBA:

SET ECHO ON;

SET SERVEROUTPUT ON;

@emremove.sql

Without the set echo and serveroutput commands you will not

be able to follow the progress of the script.

INFORMATION: --> OLAP Catalog(AMD) exists in database

Starting with Oracle Database 12c, OLAP Catalog component is desupported.

If you are not using the OLAP Catalog component and want

to remove it, then execute the

ORACLE_HOME/olap/admin/catnoamd.sql script before or

after the upgrade.

INFORMATION: --> Older Timezone in use

Database is using a time zone file older than version 18.

After the upgrade, it is recommended that DBMS_DST package

be used to upgrade the 11.2.0.4.0 database time zone version

to the latest version which comes with the new release.

Please refer to My Oracle Support note number 977512.1 for details.

INFORMATION: --> There are existing Oracle components that will NOT be

upgraded by the database upgrade script. Typically, such components

have their own upgrade scripts, are deprecated, or obsolete.

Those components are: OLAP Catalog,OWB

INFORMATION: --> Oracle Application Express (APEX) can be

manually upgraded prior to database upgrade

APEX is currently at version 3.2.1.00.12 and will need to be

upgraded to APEX version 4.2.5 in the new release.

Note 1: To reduce database upgrade time, APEX can be manually

upgraded outside of and prior to database upgrade.

Note 2: See MOS Note 1088970.1 for information on APEX

installation upgrades.

********* 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:

************ Summary ************

0 ERRORS exist in your database.

2 WARNINGS that Oracle suggests are addressed to improve database performance.

4 INFORMATIONAL messages that should be reviewed prior to your upgrade.

After your database is upgraded and open in normal mode you must run

rdbms/admin/catuppst.sql which executes several required tasks and completes

the upgrade process.

You should follow that with the execution of rdbms/admin/utlrp.sql, and a

comparison of invalid objects before and after the upgrade using

rdbms/admin/utluiobj.sql

If needed you may want to upgrade your timezone data using the process

described in My Oracle Support note 1509653.1
