Register RM clients to manage resources and access IMSplex-wide
processes.
The following steps describe how to register an RM client
first with the IMSPlex Structured Call Interface (SCI), and then with
the RMs active in the IMSPlex.
Procedure
- Identify the exit routines that are needed to drive interactions
between the CSL SCI and the client.
The SCI handles communications
between all CSL managers in the IMSplex and their client applications.
- Identify the SCI Notify exit for the client.
A
database connection can be routed through any active RM in the IMSplex,
so an RM client must registered to all RMs. A SCI Notify exit is driven
when a new RM becomes active in the IMSplex and notifies the client
with information about the new RM. The client can then register to
the new RM. The SCI Notify exit is identified with the NOTIFYEXIT
parameter of the CSLSCREG request.
- Identify the SCI Input exit for the client with the
INPUTEXIT parameter of the CSLSCREG request.
An RM client
must be able to receive RM directives sent from any RM in the IMSplex.
The SCI Input exit is driven when there is a message or request for
the client, so that the client can receive and process it.
- Issue the CSLSCREG request to SCI with the information
gathered in step 1.
A client must register to the CSL SCI
in the IMSplex before it can register with a CSL manager such as RM.
- Issue the CSLSCQRY request to SCI to determine which instances
of RM are active in the IMSplex.
Before registering with
the RMs for the first time, the client must manually identify all
active RMs with this request. Once registered, the SCI Notify exit
automatically informs the client when new RMs become active.
- Issue the CSLRMREG request to all RMs in the IMSplex that
are reachable and ready to accept registration requests.
To
manage global resources, register the resource type and associated
name type.
