Good morning I find this error in the Solution Control Interface: 'Message Server has lost connection to the Centralized Log Database'
I have the following alarm:
Name Message Server Loss of Database Connection
Category Major
Description Message Server has lost connection to the Centralized Log Database.
Application MessageServer
Log Message Connection with DB Cluster lost

And the following log from the Message Server:

I also do not see updates in the centralized logs

Thanks,
I have this error after the upgrade of Message Server from 8.1.305 to 8.5.100 on the same machine.
From the version 8.5 the Message Server have the client for db connection embedded.
The problem is solved.
