oracle database upgrade to 11.2.0.4

Here we are upgrading oracle database from 11.2.0.3 to 11.2.0.4.

Considering the OS version is Linux.

1. Check and make sure you have the latest consistent backup of database. create a restore point as well if possible.

2. Disable all the cron entries on the db server e.g. backups and other stuff which runs on db.

crontab -e

To Dissable Entry

%s/^/####/g
:wq!

3. Take the prechecks.

spool precheck.log

select name,open_mode from v$database;
archive log list
set lines 120
select TABLESPACE_NAME,EXTENT_MANAGEMENT,contents from dba_tablespaces;
select tablespace_name,sum(bytes/1024/1024) from dba_temp_files group by tablespace_name;
select file_name,bytes/1024/1024 from dba_temp_files;
col comp_name for a40
set lines 120
select comp_name,status,version from dba_registry;

select owner,object_type,count(*) from dba_objects group by owner,object_type
order by 1,2;
select owner,count(*) from dba_objects group by owner order by 1;
col owner for a15
col object_name for a35
select OWNER,OBJECT_NAME,OBJECT_TYPE,status from DBA_OBJECTS where
status = 'INVALID';
select count(*) from dba_objects where status='INVALID';
col password for a20
col username for a15
col account_statu for a15
set lines 120
select USERNAME,PASSWORD,ACCOUNT_STATUS,PROFILE,EXPIRY_DATE from dba_users
order by ACCOUNT_STATUS;

select * from v$log;
select PROPERTY_NAME,PROPERTY_VALUE from database_properties;
select * from registry$history;

SELECT DISTINCT owner
FROM DBA_DEPENDENCIES
WHERE referenced_name
IN ('UTL_TCP','UTL_SMTP','UTL_MAIL','UTL_HTTP','UTL_INADDR')
AND owner NOT IN ('SYS','ORDPLUGINS');

4. Install the 11.2.0.4 binaries to the new 11.2.0.4 directory inside product directory.

Upload the 11204 binaries zip file on the server say in cd /home/oracle/stage/. make sure the oracle database OS user have access to them. so change their ownership and permissions if needed.

As Oracle user unzip softwaresu - oracle --unzip software 11.2.0.4 unizp p13390677_112040_Linux-x86-64_1of7.zip unzip p13390677_112040_Linux-x86-64_2of7.zip

it should unzip it to one directory “database” ls database p13390677_112040_Linux-x86-64_1of7.zip p13390677_112040_Linux-x86-64_2of7.zip

Response files
Once Oracle 11GR2 binaries are unzipped you can find in directory /home/oracle/stage/database/response dedicated files called “response files” used for silent mode installations.

The response files store parameters necessary to install Oracle components:
db_install.rsp – used to install oracle binaries, install/upgrade a database in silent mode
dbca.rsp – used to install/configure/delete a database in silent mode
netca.rsp – used to configure simple network for oracle database in silent mode cd /home/oracle/stage/database/response $ ls dbca.rsp db_install.rsp netca.rsp

Install Oracle binaries cp db_install.rsp db_install.rsp.bck

Edit file db_install.rsp to set parameters required to install binaries.

once edition is completed. Start binaries installation

cd /home/oracle/stage/database./runInstaller -silent -responseFile /home/oracle/stage/database/response/db_install.rsp


output is following

Put below contents in analyze.sql using vi editor:

It can run upto 1 hour or more. once it completes,

group by owner,object_type order by owner,object_type ;

Apply psu if needed.

Connect to rman catalog and upgrade catalog using below command
upgrade catalog;
It will ask to type this command again. so type and run it again.
it would take 5 to 10 min to complete.

If all is ok, drop the restore point:
SELECT NAME,SCN,TIME,GUARANTEE_FLASHBACK_DATABASE,
STORAGE_SIZE/1024/1024/1024 STORAGE_SIZE_GB,DATABASE_INCARNATION#
FROM V$RESTORE_POINT;

drop restore point ;

Check with app team and ask them to validation everything from app side. if all is
ok, get confirmation from them to update the compatible parameter. --Update compatible patameter and restart db

alter system set compatible='11.2.0.4' scope=spfile;

Hi SA team

Can you please change below parameters in main.cf file as below tns entry :-- /opt/app/p2dti1d3/oracle/product/11.2.0.4 $ORACLE_HOME :-- /opt/app/p2dti1d3/oracle/product/11.2.0.4 compatible :-- 11.2.0.4

Revert the cron entries.

2. Enable all the cron entries on the db server e.g. backups and other stuff which runs on db.

crontab -e
