STATUS SU Command
Commands and Responses
056786 Tandem Computers Incorporated 5–191
ZDEL-TIME
shows whether subdevice is deleted after the last opener closes it.
ZRCV-CDT-WIN
shows the number of credits granted to the remote transport entity for the
current transport connection (only for connections using transport class 3 or
4). These credits are conveyed in the credit field of AK-APDUs sent to the
remote transport entity. Receive Credit can fluctuate but will never
exceed the configured L4WINDOW size. The value of this field will decrease
if the TSP process cannot handle the flow of incoming data. Once the flow of
data can be kept up with, the TSP process can gradually increase the value of
this field. If there is no connection for this SU, this field will display the value
0.
ZSND-CDT-WIN
shows the number of DT-TPDUs the TSP process is willing to send for the
current transport connection. This value will be equal to or less than, the
Receive Credit value received from the remote in the last AK-TPDU.
If there is no connection for this SU, this field will display the value of
L4WINDOW.
ZSPI-TKN-RETCODE
indicates whether or not the command was successful. If the command failed, this
token supplies the reason for the failure. Its use is described further in the
Distributed Systems Management (DSM) Programming Manual.
ZSPI-TKN-ERRLIST and ZSPI-TKN-ENDLIST
enclose a standard SPI error list, as described in the Distributed Systems
Management (DSM) Programming Manual.
ZSPI-TKN-CONTEXT
used in returning multiple response messages, is described in the Distributed
Systems Management (DSM) Programming Manual.
