Quick Steps for upgrading/patching database

These are few quick steps I performed to patch the database. Keeping here for future references -

1. Get the patch downloaded from metalink

2. Run the installation process with interactive mode - follow instruction in
the downloaded document


3. When above steps done, start database in upgrade mode
SQL> STARTUP UPGRADE

4. Run catalog upgrade script and monitor errors (if any)
SQL> @$ORACLE_HOME/rdbms/admin/catupgrd.sql

5. SQL> SHUTDOWN IMMEDIATE

6. SQL> STARTUP

7. Recompile invalid PL/SQL packages -
SQL> @$ORACLE_HOME/rdbms/admin/utlrp.sql

We are done!
