• Online mode : In this mode, the Patch Manager automates the impacted

manager server reboot and deploys middleware artifacts

Tip

Online mode will not reboot the impacted server if it's already down dur-
ing the process of applying the patch.

• Offline mode : In this mode, you have to manually reboot the impacted serv-

ers and deploy middleware artifacts

The administrative tool used to apply application patches is fapmgr.sh (Patch Man-
ager), which internally calls the following three utilities:

• Adpatch.sh : This is an AutoPatch utility used to apply database artifacts

• Adop : This is an online patching tool that provides a cut-over-based ap-

proach and reduces downtime

• OPatch : This utility is used to apply middleware artifacts

The following is the syntax for applying a patch:

Fapmgr.sh apply -patchtop <<patchtopDirectory>>
-online -stoponerror -Workers 2

The following are the high-level steps performed while applying the patch:

• Run the patch validation steps mentioned in the earlier sections

• File comparison

• Back up files that are modified by the patch

• Copy files

• Apply database components

• Deploy middleware artifacts

• Stop and start Managed Server and applications

• Update the patch information to the database (update the ad_bugs and

ad_applied_patches tables)

• Run the diagnostic report
