Defining local resources for DPL

To support DPL, special resource definitions are sometimes necessary for server programs and mirror transactions.

Mirror transactions

You can specify whatever names you like for the mirror transactions to be initiated by DPL requests. Each of these transaction names must be defined in the server region on a transaction that invokes the mirror program DFHMIRS. Defining user transactions to invoke the mirror program gives you the freedom to specify appropriate values for all the other options on the transaction resource definition.

Server programs

If a local program is to be requested by some other region as a DPL server, there must be a resource definition for that program. The definition can be statically defined, or installed automatically (autoinstalled) when the program is first called. (For details of the CICS® autoinstall facility for programs, see the CICS Resource Definition Guide.)
