Sharing the Server Map tables for 2 Servers

This is kind of a poll question.
Has anyone created a configuration where you have 2 Application Servers(one with a DBMS,one without) and pointed the "Server Map" data sources for both servers to the same tables?

What problems and or disadvantages can you think of that might occur with such a configuration?

Sure, I have done this many times. I typically dedicate a server map by platform. As long as the servers using a server map are the same platform they can generally share datasource definitions. The other tables in the server map are not platform specific and can usually be shared.

This configuration might be a problem when multiple batch servers share a single job master table. This table can grow rather large and depending on the E1 release this table may be polled constantly. (The performance problems associated with a large F986110 have been discussed on the list) With multiple batch servers sharing the table it would grow faster and larger. If this was a concern there is no reason you couldn't share the the server map but have dedicated job master tables per server. In the case of application servers this would not be an issue.
