Server Selection allows you to define on which server(s) the archiving and delete programs should run as background programs.

There must be active background processes running on the selected servers. Otherwise, the archiving or delete program will run on the database server (if a background process is available there) or on other selected application servers with active background processes.

You can create an individual server group for each archiving object or you can select a single server group for all archiving objects.

You should decide when you save the selected server group:
Save for Object means that you create a server group for a selected archiving object, Save for All Objects means that you create a server group for all archiving objects.

If you do not select a server, or if you accidentally select a server on which there are no active background processes, then the archiving program will run on the database server if a background process is available there (network load reduction). Otherwise, both the archiving program and the delete programs will be scheduled randomly on application servers where active background processes exist.

If the database server has at least one active background process and is within the server group, the archiving program will automatically be scheduled on it to reduce network load.

If you have created a server group, the system will also start other archiving-related activities within that server group, such as reloading, reading from archive files and constructing/removing indexes.
