steps to upgrade 11.1.0.6.0 to 11.1.0.7.0

steps to upgrade 11.1.0.6.0 to 11.1.0.7.0

Step1:

using winSCP or anyother tool copy the patch file p6890831_111070_Linux-x86-64.zip to the environment from the machine where you are having patch file.

Step2:
login : oracle
password:
Uncompress the binary source
$unzip p6890831_111070_Linux-x86-64.zip
Example:-
After unzipping , you can find the below folder Disk1
c111ptqhdd009: /home/oracle
$ cd /oracle/app/patches/
c111ptqhdd009: /oracle/app/patches
$ ls
Disk1 p6890831_111070_Linux-x86-64.zip

Step3:
Bring down the application


Step4:
login : oracle
password:
Bring down the database
sqlplus '/as sysdba'
sql>shutdown immediate;
sql>exit
>ps -ef |grep pmon


Make sure that oracle is not running
>lsnrctl stop
>lsnrctl status
Make sure that the listener is not running.
Take a cold database backup
Controlfiles, datafiles, redo logs, archive files, tempfiles must be included in the backup. If the files are in different paths, the same has to be backedup.
>mkdir /backup_date
>cp /App1/oracle/oradata/orcl/*.* /backup/backup_date
>cd $ORACLE_HOME/dbs
>cp inittest.ora inittest.ora_bkpdate
>cp spfiletest.ora spfiletest.or_bkpdate
>cp orapwtest.ora orapwtest.ora_bkpdate

Step5:
login : oracle
password:
Take a backup of home path
>mkdir product_bkp
>cd /App1/oracle/product
>tar czf /backup/oracle_11106.tar.gz 11.1.0


Step6:
dbhome, coraenv,oraenv backup
login : root
password:
#cd /usr/local/bin
#cp dbhome dhome_bkpdate
#cp coraenv coraenv_bkpdate
#cp oraenv oraenv_bkpdate

Step7:
login : oracle
Installation of patchset

Invoke the runInstaller using the software xming to install patch graphically.

cd /oracle/app/patches/Disk1/
>./runInstaller




Select the ORACLE_HOME to upgrade and then click next, the prerequisites steps will complete last click INSTALL. At the end up the installation it will ask to run root.sh as root user. We need root user password or sudo user privilege to run root.sh script. Follow the step 8


Step8:
login : root
password:
or
login : your_SUDU_USERNAME
password:

cd /App1/oracle/product/11.1.0/db_1
./root.sh
Or
Sudu ./root.sh

The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /App1/oracle/product/11.1.0/db_1

Enter the full pathname of the local bin directory: [/usr/local/bin]:
Copying dbhome to /usr/local/bin ... overwrite (Y/N) : Y
Copying oraenv to /usr/local/bin ... overwrite (Y/N) : Y
Copying coraenv to /usr/local/bin ... overwrite (Y/N) : Y

Step9:
login : oracle
password:

Prerequisite check before upgradation
cd $ORACLE_HOME/rdbms/admin
sqlplus '/as sysdba'
sql> startup upgrade;
sql>spool pre_upgrade.log
sql> @utlu111i.sql

If the all the values obtained above are valid, please proceed to step 10 , otherwise please correct it.

Step10:
Upgradation script execution
login : oracle
password:

cd $ORACLE_HOME/rdbms/admin
sqlplus '/as sysdba'
sql> spool upgrade_date.log
sql> @catupgrd.sql

Step11:
login : oracle
password:
Take check the validity, version of the installed components

sqlplus '/as sysdba'
sql>set pages 250
sql> set lines 1000
sql> col comp_name for a40
sql> select comp_name, version, status from dba_registry;

Note : The status column of the displayed output should be 'Valid' and the version column should be '11.1.0.7'
Upgradation ends with this step12. If in case any problem during the installation and the old version needs to be reverted back

sql>shutdown immediate;

Step12:
Recompiling the invalid objects
login : oracle
password:
cd $ORACLE_HOME/rdbms/admin
sqlplus '/as sysdba'
sql>startup;
sql>spool recompile.log
sql> @utlrp.sql


Fallback plan Or To revert back to old version (11.1.0.6.0)
1. untar the binary backup
2. Backup the database the current database and then replace them with cold back taken before applying the patch.

login : root
password:
cd /usr/local/bin
#cp dbhome_bkpdate dbhome
#cp coraenv_bkpdate coraenv
#cp oraenv_bkpdate oraenv

login : oracle
password:

oracle binary restoration
cd /App1/oracle/product
>\rm -rf 11.1.0
>mkdir 11.1.0
>cp /backup/oracle_11106.tar.gz 11.1.0
>cd 11.1.0
>gunzip oracle_11106.tar.gz
>tar -xvf oracle_11106.tar


Datafile backup restoration
cd /App/oracle/oradata/orcl/

>cp *.* /App1/oracle/oradata/orcl/
>cd $ORACLE_HOME/dbs
>cp inittest.ora_bkpdate inittest.ora
>cp spfiletest.ora_bkpdate spfiletest.ora
>cp orapwtest.ora_bkpdate orapwtest.ora


sqlplus '/as sysdba'
sql>startup;
sql>select * from v$version;
sql>select comp_name, version, status from dba_registry;

Output should be 11.1.0.6 for version column and valid for status column.

Physical Standby Database for Read/Write Testing and Reporting and revert back to the physical standby database using flashback restore point.

Using a combination of Data Guard, restore points, and Flashback Database, a physical standby database can be opened temporarily in read/write mode for development, reporting, or testing purposes, and then flashed back to a point in the past to be reverted back to a physical standby database. When the database is flashed back, Data Guard automatically synchronizes the standby database with the primary database, without the need to re-create the physical standby database from a backup copy of the primary database.

You can repeat this cycle of activate, flashback and revert as many times as is necessary.

Duplicate a database without connecting to a target database and a recovery catalog (11gR2 New Features)

Users can duplicate a database without connecting to a target database. The only requirements for this operation are a connection to a catalog and an auxiliary database. This new functionality is useful when the target database is not always available.
Users can also duplicate a database without connecting to a target database and a recovery catalog. In this case, the only requirement is that you provide a disk backup location where RMAN can find all the backups, datafile copies, archived logs, and control file copies for database duplication. This database duplication enhancement is helpful when it is not possible to connect to the target database and the recovery catalog.

here is an demo, In our example i am going to create a duplicate database with the name CLONEDB from the database DB2


1. Take backup of target database.
2. Copy the backupsets to the machine where you would like to clone the target database.
3. Create a new pfile for clone database or copy the pfile of target database and replace/edit the pfile entries for the clone database.
4. Create a password file
5. Create required folders for dump and database files.
6. Add an entry in /etc/oratab file
7. Create pfile for duplicate database
8. Add required TNS entry in tnsnames.ora file
9. startup nomount the clone/duplicate database.
10. Duplicate command in auxiliary instance.

RMAN Tablespace Point-in-Time Recovery (TSPITR) 11gR2 Enhancements

One of the good new features in 11g Release 2 is that it enables us to recover from a case of a dropped tablespace. TSPITR (tablespace point in time recovery) has been around in earlier releases, but we could not recover a dropped tablespace.

step 2:-
copy the initsunu.ora file to rac1 machine and also create a password file in rac1 machine for dbdemo database
add an entry in oratab file in rac1 machine
also move the backup files to rac1 machine to exact folder as it is in rac2(source) machine

note: make sure the folder is available in RAC1 machine
here we are taking backup in /home/u01/app/backup so now i am going to create a folder in RAC1 machine and also moving the backup from RAC2 to RAC1.
[oracle@rac2 backup]$ scp * oracle@192.168.1.1:/home/u01/app/backup/


or you can create a symbolic link for the backup location

example, in machine RAC1(the machine/host/server i dont have exact folder or exact mount point as it is in RAC2 machine(target)
do like this,

[oracle@rac2 dbs]$ cd /home/u01/app/backup/
[oracle@rac2 backup]$ pwd
/home/u01/app/backup
[oracle@rac2 backup]$ scp * oracle@192.168.1.1:/home/u01/app/test_bk/

and then create a symbolic link:
[oracle@rac1 app]$ ln -s /home/u01/app/test_bk /home/u01/app/backup

[oracle@rac1 app]$ ls
backup oracle test_bk
[oracle@rac1 app]$ cd backup/

now we are going to copy the init files from RAC2 to RAC1 machine using scp , as shown below.
you can mention hostname or ipaddress in scp command

[oracle@rac2 dbs]$ scp initsunu.ora oracle@192.168.1.1:$ORACLE_HOME/dbs/
initsunu.ora 100% 1070 1.0KB/s 00:00
***********************************************************************
IN RAC1 MACHINE
***********************************************************************

i copied the initsunu.ora file to the RAC1 machine and now i am going to replace
the database name sunu by dbdemo
also,
adding the parameter log_file_name_convert and db_file_name_convert parameters to clone database with different directory structure.

*.sga_target=745537536


Now i am going to add an entry in the /etc/oratab file for dbdemo database

dbdemo:/home/u01/app/oracle/product/10.2.0/db_1:N


going to create required folders for the dbdemo database files

[oracle@rac1 dbdemo]$ pwd
/home/u01/app/oracle/admin/dbdemo

[oracle@rac1 dbdemo]$ ls
adump bdump cdump dpdump hdump pfile udump
[oracle@rac1 dbdemo]$

[oracle@rac1 oradata]$ pwd
/home/u01/app/oracle/oradata
[oracle@rac1 oradata]$ ls
dbdemo
[oracle@rac1 oradata]$


creating a pwd file for dbdemo database

[oracle@rac1 oradata]$ orapwd file=$ORACLE_HOME/dbs/orapwdbdemo password=oracle
bash: orapwd: command not found
[oracle@rac1 oradata]$ . oraenv
ORACLE_SID = [orcl] ? dbdemo
[oracle@rac1 oradata]$ orapwd file=$ORACLE_HOME/dbs/orapwdbdemo password=oracle
[oracle@rac1 oradata]$

now i am going to start dbdemo database in nomount mode
and then do cloning

before that we should have add the tns entry of sunu database in RAC1 machine


[oracle@rac1 backup]$ cd /home/u01/app/oracle/product/10.2.0/db_1/network/admin/
[oracle@rac1 admin]$ ls -ltr

add/check this entries available in both machines else add this entry in tnsnames.ora file of both machines.

we are checking connectivity b/n the two machines using tnsping command.

now all the pre cloning steps finished.

now we can start the cloning in RAC1 machine.

Happy New Year 2011

Dear All,


“Another fresh new year is here . . .
Another year to live!
To banish worry, doubt, and fear,
To love and laugh and give!


This bright new year is given me
To live each day with zest . . .
To daily grow and try to be
My highest and my best!


I have the opportunity
Once more to right some wrongs,
To pray for peace, to plant a tree,
And sing more joyful songs!

“We will open the book. Its pages are blank. We are going to put words on them ourselves. The book is called Opportunity and its first chapter is New Year's Day.”


Thanks and Regards,
Rajesh Kumar Govindarajan
