11gR2

As 11gR2 is out for Linux, I decided to upgrade one of my existing 10.2.0.3 database to 11.2.0.1 to get the look and feel of 11gR2. Direct upgrade to 11gR2 is supported from 9.2.0.8 or higher, 10.1.0.5 or higher, 10.2.0.2 or higher and 11.1.0.6 or higher. If you have a database 9.2.0.6 then first you need to upgrade to intermediate release i.e 9.2.0.8 then to 11.2.0.1.

9.2.0.6==>9.2.0.8==>11.2.0.1
8.1.7.0==>8.1.7.4==>10.2.0.4==>11.2.0.1

I will discuss how to upgrade an existing Single Instance 10.2.0.3 database with ASM, having same ORACLE_HOME, to 11gR2 with ASM. The upgrade needs to be performed in two phases:

1. Upgrade the ASM instance
2. Upgrade the database

Upgrade ASM Instance:
===============

There are three ways to upgrade already existing ASM instance:

- Using OUI of Grid Infrastructure
- Using ASM Configuration Assistant
- Manual upgrade

The recommended method to upgrade ASM instance is to use OUI of Grid Infrastructure, which I have used .

STEP 1:

— Create OSASM group:
If you want, you can create a separate group for ASM instance here it is named as ASMADMIN.

# groupadd asmadmin
# usermod -a -G asmadmin oracle

STEP 2:

Before upgrading an ASM instance to 11gR2 it is mandatory to add a ‘user and password’ combination to the password file which is local to node’s ASM instance. Login to database instance “/ as sysdba”:

SQL> create user sood identified by oracle;
SQL> grant sysdba to sood;
SQL> select * from v$pwfile_users;

USERNAME            SYSDB SYSOP
------------------------------ -----       -----
SYS                        TRUE  TRUE
SOOD                     TRUE  FALSE

STEP 3:

From 11gR2 onwards ASM is part of Grid Infrastructure and we need to download Grid Infrastructure software first. To download the software for 11gR2 Grid Infrastructure click here

Start the RunInstaller:

./runInstaller

Click on the Image to Enlarge.

1. It will automatically defaults to the “Upgrade Mode”

Select “Upgrade Grid Infrastructure” and click Next.

2. On clicking Next, It will detect the already existing ASM instance. Shutdown the Database and ASM instance at this point.

Click “Yes”.

3.  Select the Language

Click “Next”.

4.  Enter a Password for ASMSNMP user. The password can be anything you want, though Oracle will ask you to set a password which adhers to Oracle’s standards otherwise a “Red Cross” will be shown in the tab at left hand side. Do not worry about that cross 🙂

Click “Next”.

5. Provide the Group details

Click “Next”.

Click “Yes”.

6. Provide the Base and Home location for Grid Infrastructure Home

Click “Next”.

7.  It will perform the Prerequisite checks here, For more information on this click Installation Fixup script
I have select “Ignore All”

Click “Next”.

8.  Now you will see “Summary” page, make sure that the Installation Option is shown as “Upgrade Grid Infrastructure” and Migrate ASM as “True”.

Click “Finish”.

9. Now the setup for “Grid Infrastructure’ is started

Run the rootupgrade.sh

# ./rootupgrade.sh

[root@localhost ~]# cd /u01/11g/oracle/product/11.2.0/grid/

[root@localhost grid]# pwd
/u01/11g/oracle/product/11.2.0/grid
[root@localhost grid]# ./rootupgrade.sh
Running Oracle 11g root.sh script...

The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME=  /u01/11g/oracle/product/11.2.0/grid

Enter the full pathname of the local bin directory: [/usr/local/bin]:
The file "dbhome" already exists in /usr/local/bin.  Overwrite it? (y/n)
[n]: y
Copying dbhome to /usr/local/bin ...
The file "oraenv" already exists in /usr/local/bin.  Overwrite it? (y/n)
[n]: y
Copying oraenv to /usr/local/bin ...
The file "coraenv" already exists in /usr/local/bin.  Overwrite it? (y/n)
[n]: y
Copying coraenv to /usr/local/bin ...

Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root.sh script.
Now product-specific root actions will be performed.

10. After the upgrade I have checked /etc/oratab file and found the entry of ASM pointing to new home i.e now ASM is a part of “Grid Infrastructure”
“+ASM:/u01/11g/oracle/product/11.2.0/grid:N”

Upgrade Database Instance:
===================

NOTE: DO NOT SHUTDOWN DATABASE BEFORE RUNNING DBUA.

STEP 1: Install The Software:

To download Oracle Database 11gR2 software click Here . Execute runInstaller to install “SOFTWARE ONLY” option, you can follow this link to install the software.  Make sure that you select “software only”  option as shown below rest of the steps are same as described in above link.

STEP 2: Run Pre-Upgrade Information tool

I have installed the software under “/u01/11g/oracle/product/11.2.0/dbhome_1” location. Once the software is installed, then go to location $ORACLE_HOME/rdbms/admin and copy  utlu112i.sql script to /tmp directory. Now login to 10g database “/ as sysdba” and startup the 10g database, then:

SQL> spool /tmp/upgrade.spl
SQL> @/tmp/utlu112i.sql
SQL> spool off</span>

Following is the output of this script from my database:
