When creating a new webengine in a Service Desk Conventional Configuration, you may notice that the "Object Manager" field can be set to "Default".
Release: CA Service Desk Manager 17.X
Webengines require access to at least one Object Manager, or domsrvr, in order to function correctly. What happens when you choose the "Default" setting for Object Manager on a given webengine is that the given webengine will then be tied to the primary server's domsrvr. This is considered to be the "Default" domsrvr as it is always defined in all Conventional Configurations of Service Desk.
The danger of using this domsrvr appears if one were to define multiple webengines and tie them all the same "default" domsrvr, which will cause the given domsrvr process to become overloaded with all of the webengines' object requests, and can lead to severe performance degradation.
The ideal approach is to create a domsrvr on the same server as the webengine and have the given webengine tied to the local domsrvr.
To do this:
The following tech doc describes how to add a secondary server using the Administrative Web Interface for creating configurations in SDM 12.9 onwards.
