Setting Up the MVS Server
Setting Up the MVS Server
Summary: The first task in the APPC configuration process requires you to set up the
MVS Server. The MVS Server uses the APPC/MVS Server Facilities
introduced in MVS/ESA SP 4.3.0. In this section, the term APPC/MVS is
used to represent the APPC/MVS Server Facility, and the term server refers
to the MVS Server.
Before You Begin
The server selects inbound conversations on the basis of the named
application, TP name, its location in the network, and the LU name.
• The TP name is a 1- to 64-character name describing the server’s address
space. Inbound requests are directed to this location. The TP name may
be the started task name or job name of the server’s address space.
• The logical unit (LU) name is a unique name defined to the VTAM
network for the server application.
After APPC/MVS receives a client request for a conversation, APPC/MVS
checks whether any address space has registered to serve the request. If so,
APPC/MVS assigns the request to an allocation queue. The server can then
select the request from the queue for processing. When the server selects the
request from the queue, it receives the conversation ID, and a conversation
with the client begins.
Because APPC/MVS requires the server to register and unregister for
services, the server must be shut down in an orderly way to be unregistered
as an APPC/MVS Server. Cancelling the server is not recommended. You
can use an MVS console
STOP command (P) to stop the server. Alternatively,
you can use an MVS modify
STOP command (F) to shutdown the server task
in an orderly fashion. For a list of available MVS console commands, see
Table 4-3 on page 4-29.
