Listing Open Requests
Note that a LISTOPENS PROCESS display for an initiator or responder should always
show the SCF and APLMGR openers; for an APLMGR process, the display should
always show the SCP opener. If the same application has opened a specified initiator
process more than once, a separate line of information is displayed for each open.
The LISTOPENS PROCESS command provides information necessary for situations in
which you are trying to terminate processes using the STOP command. The STOP
command is effective on a process only if no work is in progress. By using the
LISTOPENS command, you can determine if a process is currently servicing any
requests. The opens for SCP ($ZNET) and the APLMGR process should always appear
for initiator or responder processes. Any additional openers to initiator processes
indicate that the process is doing work for an application.
The LISTOPENS command is most useful in troubleshooting. If the total number of
pending requests for an initiator process is high, this can be an indication that the
workload is not being evenly distributed.
Subdevices
You can retrieve the same type of open information for initiator subdevices by issuing
the LISTOPENS SU command. Note the following example:
LISTOPENS SU $FTI1.#Z000002
LISTOPENS SU returns a display in the same format as LISTOPENS PROCESS, but
lists opens to the named subdevice: in this case, #Z000002.
The display returns only the process that is using the subdevice; it does not return an
APLMGR or SCP name. Use this command to monitor opens of subdevices. If the
subdevice is not currently being used, the text NO OPENS is displayed in place of the
process name.
Since there is no application on the Tandem system to open a responder subdevice, the
LISTOPENS SU command is not valid for responder subdevices.
