Environment

Release : 10.1

Component : APP SYNTHETIC MONITOR

Resolution

Since there was an earlier install of OPMS with subaccount, thus it is suggested that we remove OPMS properly.

We have following information in online guide how to remove .

Step 1 and 2 is not necessary. i.e. Assign a New Tunnel Client and Unregister the OPMS
It is not being used as Tunnel Client and OPMS is not registered in ASM.

Step 3, we need to do this as we do not want any item from the earlier install of OPMS with subaccount

Step 3 Uninstall the OPMS
The installer does not support uninstalling. After decommissioning the OPMS, wipe the drive or revert a filesystem snapshot.

than we are able to complete the installation successfully.
