Distributed Programming Link (DPL) adapter

The DPL server adapter performs distributed programming links to CICS applications using the EXEC CICS LINK command.

If you are modeling a flow using WebSphere® Developer for System z® version 6, a DPL server adapter is generated for every distributed programming link. If the flow is simple, and only generates a single DPL server adapter, it is handled directly by the navigation manager at run time. If the flow is complex, and generates many server adapters, these are controlled using an adapter navigator.

The maximum COMMAREA length that can be passed from this server adapter to the target application is 32,767 bytes. 267 bytes are taken up by the message header, and the remaining 32,500 bytes can be used for application data.

If you are modeling a flow using WebSphere Developer for System z version 7, a standard DPL server adapter called DFHMASDP is invoked for all distributed programming links in the adapter service. As DFHMASDP is handling all of the distributed programming links, it is always invoked by an adapter navigator and runs under the CMAS transaction. The processing that takes place when DFHMASDP is invoked is the same as existing DPL server adapters generated by WebSphere Developer for System z version 6 flows.
