establish a new connection. You can also send PARAM messages to the TSP process.
Refer to the Tandem OSI/TS Manual for details.
Closing and Stopping a
TSP Process
Since your application does not open the TSP process directly, it does not need to close
it when finished. It need only close the SCP, as described in the Communications
Management Programming Manual.
Your application can stop a TSP process by sending an OSI/TS STOP or ABORT
programmatic command. However, if you stop or abort the TSP process, the process
is deleted; it must be rerun using a RUN command or a NEWPROCESS or
PROCESS_CREATE_ call, as described earlier, before it can be started again.
Normally, NSP processes run continuously once they are installed through SYSGEN.
You cannot stop NSP processes by using OSI/TS commands. For more information
about NSP processes, refer to the X.25 Access Method (X25AM) Manual or the
Multilan/TLAM Management and Operations Manual.
Running an EMS
Consumer Distributor
Before your application can retrieve event messages generated by OSI/TS and other
subsystems, you must start an Event Management Service (EMS) consumer distributor
process, open this process for SPI communication, and specify the source of event
messages with a CONTROL command. The Communications Management Programming
Manual gives summary instructions for these steps, and the Event Management Service
(EMS) Manual provides full details.
To avoid receiving all event messages from all subsystems (something you will rarely
want to do), you must install a filter to select only those messages upon which your
application is to act. You install your filter when you start the consumer distributor.
Filters are written in the EMS filter language, which is described in the Event
Management Service (EMS) Manual. Appendix C provides several examples of filters
that you could use for events generated by OSI/TS and related subsystems.
