While applying patch to binary using opatch utility got below error.

ZOP-51: The patch location is not valid for apply, because it doesn’t have correct metadata, or it points to a patch directory.

Argument(s) Error… Patch location is not valid for apply

Please check the arguments and try again.

OPatch failed with error code 135




This error comes, if we are running opatch command from a directory other than patch directory.

So,Make sure we are running the opatch command for patch directory.



cd 16056266 – >> current patch directory

./opatch apply 


Now it worked successfully, without any error.
