This post demonstrate a step by step guide to apply oracle patchset 10.2.0.4 (patch number 6810189) on 10.2.0.1 database. My current environment is Oracle 10gR2 (10.2.0.1) installed on Redhat Enterprise Linux 5 update 4 32-bit.
Stop all oracle components running like LISTENER, EM , ISQLPLUS and DB itself etc.
/* Stop the isqlplus if running */ $ isqlplusctl stop iSQL*Plus 10.2.0.1.0 Copyright (c) 2003, 2005, Oracle. All rights reserved.

Once the oracle database is shutdown, take a cold backup of your database and a backup of your ORACLE_HOME.
$cd /u01/apps/oracle/oradata/ /* All my data files , control files and log files are in a directory ora10g at the location /u01/apps/oracle/oradata/. I am going to make a tar archive of ora10g directory. If these files are at separate locations then add all those locations into the tar archive. And since this is just a test database and is very small in size so tar archive works much better then every thing else. But if it would be a production db and is big in size then I would consider other faster ways to take a cold backup of my data files. */ $ tar czf /home/oracle/ora10g.tar.gz ora10g $ echo $ORACLE_HOME /u01/apps/oracle/product/10.2.0/db_1 /* This is my ORACLE_HOME so I would make a tar archive of "db_1" directory. */ $ cd /u01/apps/oracle/product/10.2.0/ $ tar czf /home/oracle/oraHomeBackup.tar.gz db_1
(Only perform this step if you have data or Scheduler jobs
with TZ info)
From 9i onwards Oracle has 2 datatypes that may have data stored affected by a update of the RDBMS DST (Daylight Saving Time) definitions, those are TIMESTAMP WITH LOCAL TIME ZONE (TSLTZ) and TIMESTAMP WITH TIME ZONE (TSTZ). If you have TZ data stored in your database you need to go through the following steps to ensure the integrity of your data while the database upgrade.
Check which TIMEZONE version file you are currently using.
SQL> select version from v$timezone_file;
VERSION
----------
2
If this gives 4 then you may simply proceed with the upgrade even if
you have TZ data.
If this gives higher then 4, look at the meta
link note:
If this gives lower then 4, perform the following
steps:
Download and run it.
SQL> @utltzpv4.sql
DROP TABLE sys.sys_tzuv2_temptab CASCADE CONSTRAINTS

ERROR at line 1:

Your current timezone version is 2!
.
Do a select * from sys.sys_tzuv2_temptab; to see if any TIMEZONE
data is affected by version 4 transition rules.
.
Any table with YES in the nested_tab column (last column) needs
a manual check as these are nested tables.

If it returns no rows, there is nothing that needs to be done. Just
proceed with the upgrade.
If it retunrs the detail of columns that
contain TZ data which may be affected by the upgrade, see metalink
note:
The Note 553812.1 states that if you see SYS owned SCHEDULER objects then it is safe to ignore them and proceed with the upgrade. But if you see user data or user created jobs here then you need to take a backup of data before upgrade and restore it back after the upgrade. Remove any user created jobs and re-create them after the upgrade.
Now is the time to prepare the oracle 10.2.0.4 patchset installer.
You can download the patchset from
Once downloaded login as root in another console and execute following:
# xhost +SI:localuser:oracle
Now come back to the oracle user console and move to the directory where you downloaded the patch and unzip the file.
$ cd /home/oracle $ unzip p6810189_10204_Linux-x86.zip $ cd Disk1/ $ ./runInstaller
The first screen is welcome screen
Provide the Oracle home details here (The oracle 10.2.0.1 home).
The installer will perform prerequisite checks on this screen. Make sure you see the message "The overall result of this check is passed" in the output.
Oracle configuration Manager allows you to associate your configuration with your metalink support account. You may skip this
Installation Summary.
Installation progress.
Once progress shows 100%, you will be asked to perform some root specific actions.
Login as root
# which dbhome
/usr/local/bin/dbhome
/*
this shows the location of dbhome, oraenv and coraenv files
rename them for 10.2.0.1 as the root.sh create new ones for
10.2.0.4
*/
# cd /usr/local/bin/
# mv dbhome dbhome_10201
# mv oraenv oraenv_10201
# mv coraenv coraenv_10201
/* Now execute the script suggested by the installer. */
# /u01/apps/oracle/product/10.2.0/db_1/root.sh
Running Oracle10 root.sh script...
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u01/apps/oracle/product/10.2.0/db_1
Enter the full pathname of the local bin directory: [/usr/local/bin]:
Copying dbhome to /usr/local/bin ...
Copying oraenv to /usr/local/bin ...
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.When root.sh finishes successfully come back to installer and press ok. Then you should see the End of Installation page as below.
Press exit and your ORACLE_HOME is patched with 10.2.0.4 patchset. All your db's working under this ORACLE_HOME will become unusable unless you upgrade your database to 10.2.04 as well.

As you can see the database is unable to open and throwing the error ORA-01092. Lets look at the alert log file to know what actually happened.

The alert log states that the database has to be upgraded first using UPGRADE option to be able to OPEN normally.
Now startup the database with upgrade option and run the pre-upgrade information tool to see if the database is okay for the upgrade and if there is some thing to be changed before starting the upgrade.

When the upgrade script catupgrd.sql finishes shutdown the database and open the spool of the upgrade process and try to find out if any thing failed. If you see something failed try to fix it and re-run the upgrade process.
The upgrade process may leave many objects invalid in the database. Perform a normal startup and run the utlrp.sql script to recompile any invalid objects.

Let's suppse the upgrade process fails, then you can always go back to 10.2.0.1 level be restoring the backup we took at the beginning of the process and start over the upgrade.
Just shutdown the database and restore the backups as follows:
$ echo $ORACLE_HOME /u01/apps/oracle/product/10.2.0/db_1 $ cd /u01/apps/oracle/product/10.2.0/ $ rm -fr db_1 $ tar xzf /home/oracle/oraHomeBackup.tar.gz * /* This will restore the old ORACLE_HOME */ $ cd /u01/apps/oracle/oradata/ $ rm -fr ora10g $ tar xzf /home/oracle/ora10g.tar.gz * /* This will restore a consistent copy of datafiles, controlfiles and redo log files */
Now start the database and see which version is it?
