The document provides instructions for upgrading an Oracle database from version 11.2.0.2 to 11.2.0.4. The key steps include: 1. Performing pre-upgrade tasks such as checking disk space, authorizations, and database backups. 2. Installing the Oracle 11.2.0.4 software, applying required patches, and setting environment variables. 3. Running pre-upgrade scripts, setting more environment variables, and using the Database Upgrade Assistant tool to perform the upgrade. 4. Performing post-upgrade tasks like starting up the upgraded database.

1.3 Check
Authorizatio

1. Check write authorization for the /oracledirectory
reuxgbuz338:oracxl>touch /oracle/write_test
reuxgbuz338:oracxl>rm /oracle/write_test
rm: remove /oracle/write_test (yes/no)? Yes
2. Test GUI Launch
reuxgbuz338:oracxl>/usr/openwin/bin/xclock
3. Set umask
reuxgbuz338:orawyl> umask 022
4. Ensure "root" permission to run root.sh after DB Software Install.
If no write authorization,performbelow as root.
chgrp dba /oracle
chmod 775 /oracle
1.4 Copy Oracle

software
orawyl>cd /oracle/stage
orawyl>mkdir /oracle/stage/11204

Backup
1. OracleHome
oracxl>cp -rp /oracle/CXL/11203

oracxl>cp -rp /oracle/CXL/oraInventory
/backup/CXL_BACKUP_RANGP4_DND_02072014
For DB Software installation and upgrade,database
must be runningon server where "/oraInventory" is
present. Because for clustered DB '/oraInventory'
will beavailbleonly on any one of the server.
