Obtaining Resources

An initialization/termination program can obtain any resources that its servers require or share. For example, the initialization/termination program can:

Open data sets that the servers need.
Obtain storage, such as a work area to be shared among the servers, by issuing the GETMAIN macro.

The initialization/termination program makes resources available to the server by pointing to them in a server parameter list (parmlist) as part of the server definition process. When MVSSERV passes a service request to the server, it passes the server parmlist list as well.
