Cross-System NetIPC

Program Startup

NetIPC itself does not include a call to schedule a peer process. In

programs communicating between multiple HP 3000 systems, you can

use the Remote Process Management (RPM) call, RPMCREATE, to

programmatically schedule program execution. However, RPM between

HP 3000 and HP 1000 systems, and between HP 3000 and HP 9000

systems, is not currently supported by Hewlett-Packard. Instead, you

must manually start up each NetIPC program on its respective system.

HP 3000 Program Startup

To manually start up an HP 3000 NetIPC program, log on to the

HP 3000 and run the NetIPC program (with the RUN command).

You can schedule the program to start at a particular time by writing a

job ﬁle to execute the program, and then including time and date

parameters in the :STREAM command that executes the job ﬁle.

HP 1000 Program Startup

To manually start up an HP 1000 NetIPC program, simply logon to the

HP 1000 system and run the NetIPC program with the RTE XQ (run

program without wait) command.

To have the NetIPC program execute at system start up, put the RTE

XQ command in the WELCOME ﬁle.

HP 9000 Program Startup

Remote HP 9000 processes can be manually started or can be scheduled

by daemons that are started at system start up. In HP-UX a daemon is

a process that runs continuously and usually performs system

administrative tasks. Although a daemon runs continuously, it

performs actions either at a speciﬁed time, or upon a speciﬁed event.

To manually start up a NetIPC program, simply logon to the HP 9000

system and run the NetIPC program. HP recommends that you write a

NetIPC daemon to schedule your NetIPC programs. You can start the

daemon at start up by invoking it from the /etc/netlinkrc ﬁle. Refer

to the NS/ARPA Services/9000 Series 800 Node Manager’s Guide for

more information about this ﬁle and system start up.
