What is Opatch?
OPatch is a java based utility.

How to know which version is the correct version of Opatch for your RDBMS home?
You can verify whether the Opatch version for your RDBMS release is correct or not using metalink note ID 357221.1.
This note ID gives the copatibilities between OPatch version and RDBMS version.
How to get the latest version of OPatch?

In the release dropdown you can select the OPatch release that you want to download based on your RDBMS version. Please read the README.txt before applying the patch.

How to apply a single patch using opatch
You MUST read the Readme.txt file included in opatch file, look for any prereq. steps/ post installation steps or and DB related changes. Also, make sure that you have the correct opatch version required by this patch.
Make sure you have a good backup of database.
Make a note of all Invalid objects in the database prior to the patch.
Shutdown All the Oracle Processes running from that Oracle Home , including the Listener and Database instance, Management agent etc.
You MUST Backup your oracle Home and Inventory
Unzip the patch in $ORACLE_HOME/patches
If you are applying a single intrim patch to oracle home, then change the location to the directory of that patch and then invoke following command.
Example if I need to apply patch 6972343 to RDBMS Oracle Home
-bash-3.00$ cd 6972343
etc files README.txt
If you have created local inventory then you need to give the correct path for local inventory stored in oraInst.loc. If you have updated /etc/oraInst.loc with correct location of your inventory, then above command will work, If not you can give the correct location by giving local oraInst.loc file.
$ORACLE_HOME/OPatch/opatch apply -invPtrLoc /slot/ems2029/oracle/db/tech_st/11.1.0/oraInst.loc
Remember that when we are applying patch, patch number is NOT provided as an input to opatch command. So we have to to be in the directory of patch since opatch will pick the patch files from current directory.
Rolling back a patch
In case if a patch did not fix the issue or if you has applied wrong patch to oracle home, you can always rollback the patch using following comamnd.
opatch rollback -id <Patch Number>
Applying bundle patches
Some times if you have to apply bundle patch having many patches, example lets say you want to a bundle patch 6778860 (184.108.40.206 BUNDLED PATCH FOR EBS 11I)) containing many other patches to RDBMS home, OPatch provides a facility to apply many patches to RDBMS home using a single comamnd. Following command should be used for applying bundle patches.
Download the patch and extract the same. You will see many directories (one for each patch) inside the main patch directory. Execute following command to apply all patches.
$ORACLE_HOME/OPatch/opatch util NApply -invPtrLoc /slot/ems2029/oracle/db/tech_st/11.1.0/oraInst.loc
NApply -> Will apply all patches to RDBMS home.
You can also use -phBaseDir to point to the directory where bundle patch is installed. So you can run opatch command from any location
$ORACLE_HOME/OPatch/opatch util NApply -phBaseDir /slot/ems2029/oracle/db/tech_st/11.1.0/patches/6778860 -invPtrLoc /slot/ems2029/oracle/db/tech_st/11.1.0/oraInst.loc
You can also apply specific patches using NApply
opatch util napply <patch_location> -id 1,2,3 -skip_subset -skip_duplicate
This will apply patches 1, 2, and 3 which are under < the patch_location> directory. OPatch will skip duplicate patches and subset patches (patches under <patch_location> that are subsets of patches installed in the ORACLE_HOME)
You can see all the options for NApply using following help command.
$ORACLE_HOME/OPatch/opatch util NApply -help
Query the inventory for patches applied
We can query the inventory to check various components installed for database as well as to check various patches applied to database. Use following command to get a minimum information from inventory about patches applied and components installed.
$ORACLE_HOME/OPatch/opatch lsinventory -invPtrLoc /slot/ems2029/oracle/db/tech_st/11.1.0/oraInst.loc

If you are using central inventory then -invPtrLoc variable is not required.
You can also get the detailed view of inventory using following command. In case of detail information it gives which are the files that this patch have touched.
$ORACLE_HOME/OPatch/opatch lsinventory -detail -invPtrLoc /slot/ems2029/oracle/db/tech_st/11.1.0/oraInst.loc

Which options are installed in Oracle Home?
You can check the options installed in RDBMS home using above command. The options installed will be listed at the start of output.
Example: $ORACLE_HOME/OPatch/opatch lsinventory -detail -invPtrLoc /slot/ems2029/oracle/db/tech_st/11.1.0/oraInst.loc
