Conversations

Establishing Conversations

6. Tell the node manager the executable ﬁle name of the TP. The

executable ﬁle may reside in any group and account. The node

manager will create a job to run the TP.

7. Tell the node manager whether the TP calls the MCGetAllocate

intrinsic multiple times or only once. The node manager must

conﬁgure the TP to accept either single or queued allocate requests.

8. Decide whether you want to start the TP yourself or have the APPC

subsystem start the TP. While you are debugging the TP, you might

want to start it yourself. However, once the TP is working, you

should have the APPC subsystem start the TP when it receives an

allocate request from the remote TP. Tell the node manager whether

to conﬁgure the TP for manual or automatic startup.

9. Tell the node manager how long the local TP should wait for an

allocate request from the remote TP before the MCGetAllocate

intrinsic times out. The node manager will conﬁgure the time-out

value.

Node Manager Tasks

To prepare for a remotely initiated conversation on MPE XL, the node

manager must do the following:

1. Conﬁgure an appropriate session type.

2. Tell the application programmer the name of the session type. The

programmer must code the name of the session type into the local

TP.

3. Activate a session of the appropriate session type, or conﬁgure one

for automatic activation at subsystem startup.

4. Create a job that runs the executable TP ﬁle. See the APPC

Subsystem on MPE XL Node Manager’s Guide for more information.

5. Conﬁgure the TP name, the job name, the time-out value, whether

the TP accepts queued allocate requests, and whether the

programmer will start the TP manually. See the APPC Subsystem on

MPE XL Node Manager’s Guide for information on TP conﬁguration.

Remote Programmer Tasks

To prepare a remote program to initiate a conversation with an HP TP

on MPE XL, the remote programmer must do the following:

1. Design and code the program to initiate a conversation with the

corresponding TP on the HP 3000.

2. Make sure that the remote TP passes the proper TP name in the

allocate request. The HP application programmer must tell the

remote TP programmer which TP name to use.
