There are times when, in a loosely coupled or a multiple database function (MDBF) environment, you will need to interrogate or update the status of processors and subsystems other than the one with which you are currently communicating. You may also have a need to communicate with a remote TPF processor to determine the status of some part of that system. The TPF system provides a prefixing facility to allow you to make the necessary inquiries and updates to other processors and subsystems to help you solve problems and be more productive. Figure 1 shows an example of a system comprised of a loosely coupled environment that includes processors B and C with MDBF, and uniprocessor A attached through a cross-domain link. Assume terminal 123B is logged on to SMPB, which is in the basic subsystem (BSS) of processor B.
The following are the possible prefixes for the environment described in Figure 1:
SMPC/message
AAAA/message
SS2/message
SMPC/SS2/message
SMPA/message
ALL/message
ALL/SS2/message
Notes:
See Prefixing Messages for more information about message prefixing.
