I recently upgraded a customer database from 10.2.0.4 to 11.2.0.3.2 and wanted to share the procedure that I followed. It is a pretty straightforward upgrade, similar to many others that I have done. The one thing that was new to me was upgrading the Time Zone files with the DBMS_DST package.
I used the following Metalink Notes to come up with this procedure. While most of the following steps would apply to any database, it is important that you review these documents and make sure that your particular situation is covered. For example, if you are running Database Vault, there are some required steps that are not mentioned in this document. Also, if your application uses UTL_TCP, UTL_SMTP, UTL_MAIL, UTL_HTTP, or UTL_INADDR packages, then you will need to perform certain operations to allow continued access.
Complete Checklist for Manual Upgrades to 11gR2 [ID 837570.1]
Actions For DST Updates When Upgrading To Or Applying The 11.2.0.3 Patchset [ID 1358166.1]
Updating the RDBMS DST version in 11gR2 (11.2.0.1 and up) using DBMS_DST [ID 977512.1]
Pre-Upgrade: These steps can occur prior to the actual database upgrade
Step 1) Install 11.2.0.3 (patch 10404530) into /opt/app/oracle/product/11.2.0/db_1
Step 2) Install latest version of OPatch (patch 6880880)
Step 3) Install 11.2.0.3.2 PSU (patch 13696216)
Download patch 13696216 to a staging location
cd <staging location>/13696216
opatch apply
Step 4) Run utlu112i.sql and resolve any issues.
Download this script from Note 884522.1 and run it as SYSDBA. It will list issues that need to be resolved before the upgrade can succeed. Create a modified init.ora based upon the output of this script. All of the *dump_dest parameters are replaced by the diagnostic_dest parameter. Increase tablespace size, SGA size as recommended. Copy it to the new $ORACLE_HOME/dbs
Note: if you don’t run this script prior to the upgrade, it will cause the upgrade to fail
Step 5) Run dbupgdiag.sql and resolve any issues
Step 6) Check for database dictionary corruption
This script came from Note 837570.1 and will detect any logical corruption in data dictionary objects.

Seriously, take a full, cold backup of your database. It probably won’t be needed but you don’t want to bet your job on it, do you?
Step 3) change /etc/oratab and reset environment variables with oraenv
Step 4) Upgrade the Database

commit;Step 6) Update Network config files
Change ORACLE_HOME in listener.ora and copy files to new $ORACLE_HOME/network/admin. Start the listener and check connectivity
Step 7) Modify cron jobs, profiles, etc that may have $ORACLE_HOME hard-coded.
Step 8 ) Move any Media Management Libraries to the new $ORACLE_HOME/lib
If you do RMAN backups directly to tape, you likely have a symbolic link called libobk.so in $ORACLE_HOME/lib pointing to Media Management software (Netbackup, Legato, etc). This needs to be recreated in the new $ORACLE_HOME
Step 9 ) Check for any new accounts that should be locked.
Depending on what options are installed, Oracle may create new users. Unless you are going to use that functionality, these accounts should be locked.
