OMS 12c : 12.2 ASM / Database /Grid Infrastructure Targets are Shown as Down

We will be able to add 12.2 database in and also test connection will work fine in moitoring configuration page.

But in the target page it will be shown as down with the below error

ORA-28040: No matching authentication protocol

The same occurs for ASM and cluster targets too.

This is because OMS is certified to monitor only DB versions below


1. For monitoring 12.2 DB and related targets, OMS needs to be at least of release with DB plugin.

2. If this issue occurs in release too, ensure that the latest DB and Agent bundle patches are applied at the Agent.
