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.
Note:
Before applying a patch on multiple hosts, ensure that you have created a topology file using Fusion Middleware Composer. You must supply this file on the command line using the -topology
option when you run OPatchAuto. OPatchAuto uses this file to obtain information from your environment to identify the configuration that you want to patch. For an example on how to create a topology file, see Building A Topology Using Fusion Middleware Composer.
Patching a multi-host environment with OPatchAuto involves the following tasks:
opatchauto apply —analyze
command to check for any prerequisites. For multi-host patching, you must provide the Fusion Middleware Composer topology file using the -topology
argument.opatchauto apply
command. This is the same command as opatchauto apply —analyze
, except you remove the -analyze
argument when you are ready to apply the patch.opatchauto rollback
command to roll back the application of a patch. This is the same command as opatchauto rollback –analyze
, except you remove the -analyze
argument when you are ready to roll back the patch.
