Problem(Abstract)
While installing the perf.tuning, installation of Fix Pack 2 failed with an error 180, the Dynamic loading of a class failed. This same error has occurred on other components other than perf.tuning.

  2. Download the latest updateinstaller. The bug has been resolved in the latest updateInstaller, PQ77502. Verify that this fix is included in the updateInstaller that you are using.

  3. Source the setupcmdline.sh/bat. Verify that no Java™, HTTP or Application Server processes are running.
