The TPI Object The TPI object type, ZCOM-OBJ-TPI, is used when the object of a control or inquiry
operation is a local instance of a transaction program. The TPI object can be a Tandem
process or a thread within a Tandem process. A TPI object can be created by a TP
issuing a TP-READY service verb. It can be deleted by a TP issuing a TP-END service
verb, an ABORT or STOP command, or a file system CLOSE request.
The object name for the TPI object is tpi-id, and it has the following format:
$apc-process.local-lu.tpn.tpi-id
$apc-process
is the name of the SNAX/APC process.
local-lu
is the name of the parent LU object.
tpn
is the name of the parent TPN object.
tpi-id
is the name of the TPI object. It is assigned by the SNAX/APC process and
uniquely identifies a TP instance. Its is an unsigned integer that is represented in
commands and responses as a 4-digit hexadecimal string. It is not necessary to
have the %H prefix for tpi-id because it will always be a hexadecimal integer.
