Exam 1z0-078 topic 1 question 9 discussion

I think it is a bad question. Techinically, DBA can use absolute path to use OPatch utility without setting PATH environment parameter. Also, the question is intended to ask which process must be done before issuing "OPatch" utility. As a result, if you would like to use "opatch version" to check the version of p6880 utility, you should set PATH parameter first. After that, you should stage the patch on the cluster where the OPatch utility will be executed. So, I would like to pickup "C: Update the PATH environment on the node where you will run..."

You can use opatch -oh option instead of $ORACLE_HOME env but you have to have patch files on a node being patched. Thus, answer is B

A: Incorrect. You only need to update the PATH on the node where you'll run OPatch, not on all nodes. B: Incorrect. Staging the patch on the execution node is essential but doesn't address updating the PATH. D: Incorrect. Staging the patch on all nodes is redundant and unnecessary. C: Correct. You must update the PATH environment variable on the node where you will run the OPatch utility to point to the $ORACLE_HOME/OPatch directory.

I think C

D looks to be the answer, since the question is about using opatch with GI

I think the question is tricky... OPatch: A Java-based utility that enables the application and rollback of patches to Oracle software. OPatchauto: A patch orchestration tool that generates patching instructions specific to your target configuration and then uses OPatch to perform the patching operations without user intervention. for opatchauto the patch can be copied on 1 node for opatch utility the patch must be copied on all nodes The question is about Opatch - I think D is correct

patch can be copied just on the 1 node
