Explanation:
OPatchauto is Oracle's strategic tool for binary and configuration patching. For the supported environments, OPatchauto sequences and executes all required steps, on all nodes, for comprehensive patch application.
Note: The OPatchauto commands are run from the product home out of the standard OPatch directory.
Example:
$PRODUCT_HOME/OPatch/OPatchauto apply <PATH_TO_PATCH_DIRECTORY>
where <PATH_TO_PATCH_DIRECTORY> is the full path to local staging area where you have downloaded your patches.
The apply command applies a System Patch to a product home. User specified the patch location or the current directory will be taken as the patch location. .
