To verify that a patch can be applied on a single host, use the —analyze argument to the OPatchAuto apply command. For single host patching, you must also provide the domain location using the —instance argument.
The following command shows how to verify the prerequisites for applying a patch on a single host:
opatchauto apply PATCH_HOME -analyze -instance DOMAIN_HOME -wallet wallet_location -walletPassword password_ifneeded -wls-admin-host weblogic_adminserver_host:port
For example:
opatchauto apply /home/oracle/patches/15941858 -analyze -instance /home/oracle/config/domains/exampledomain -wallet /tmp/samplewallet -wls-admin-host examplehost.exampledomain.com:7001
If you want to apply multiple patches in one session, use the –phBaseDir option.
This command analyzes and displays the actions that will be taken by the patch, but does not actually apply the patch. As a result, it allows you to verify that the prerequisites for the patch have been met.
If any prerequisite checks fail, refer to the output and log file to fix the issues before continuing. For example, a common failure is the detection of patch conflicts. If any patch conflicts occur, follow the instructions in the log file for how to obtain a merge patch from Oracle Support.
