If you want to make sure what hotfix has been applied to either the SCA or OA, you need to take a look to their logs when starting the agent.
For example, after starting the SCA you should encounter something like this in the server.log:
- Stat: 6.2.0.516
- © 2018 Quest Software Inc. All Rights Reserved.
And in the Oracle Agent logs you should encounter something like this:
- Copyright 2017 Quest Software Inc. All Rights Reserved.
- Version: [6.2.0.631]
You can clearly see the minor versions, in both logs, that refers to the hotfix applied.
To make sure that Stat 6.2 HF-G has been applied, look into the hotfix release notes and you will find there what minor version should the agents have.
