2.2 Using OPatchAuto to Patch Oracle Fusion Middleware

Use OPatchAuto to automate the necessary steps for applying a patch on a single host or multi-host environment.

The following topics describe how to use OPatchAuto to patch Oracle Fusion Middleware.

• Summary of the Steps For Using OPatchAuto in a Fusion Middleware Environment
  Applying a patch with OPatchAuto involves a series of steps that must be performed to ensure successful patching.
• Applying a Patch on a Single Host Using OPatchAuto
  After you obtain the patches required for your installation, use the opatchauto apply —analyze command to verify prerequisites, and then use opatchauto apply —instance to apply a patch on a single host. If needed, you can use opatchauto rollback to roll back the application of a patch.
• Applying a Patch on Multiple Hosts Using OPatchAuto
  After you obtain the necessary patches, use the opatchauto apply —analyze command to verify prerequisites, and then use opatchauto apply —topology to apply a patch on multiple hosts. If needed, you can use opatchauto rollback to roll back the application of a patch.
• Troubleshooting a Patch by Viewing the OPatchAuto Log File
  To understand how a patch is applied and to troubleshoot any problems with the application of a patch, you should review the log file for the OPatchAuto session.
• Using the OPatch lsinventory Command to Verify the Patches Applied to an Oracle Home
  To verify what patches have been applied to an Oracle home, or to find out additional information about the Oracle home, use the opatch lsinventory command.
• Using the listDomainPatchInventory.sh Command to Verify the Patches Applied to a Domain
  To verify what patches have been applied to a domain, use the listDomainPatchInventory.sh command. Use this command with the OPatch lsinventory command to verify that the patch has been applied successfully.
• Verifying Your Installation After Applying a Patch
  After you apply one or more patches successfully, use the WebLogic Administration Console, Fusion Middleware Control, and your organization’s application testing to verify that your system is currently running successfully.
