Displaying Subsystem Statistics
To find out how current subsystem activity compares with activity at peak periods, issue
the STATS SUBSYS command. This command is valid only if directed at the APLMGR
process, as in this example:
STATS SUBSYS $AMGR
The command returns the following display:
This display shows that the counters were recently reset, and that there are two initiator
and two responder processes and one VFS profile currently configured. The display also
shows the number of register requests that have been received by the APLMGR process
since the last reset, the number that have succeeded in establishing communication with
an FTAM initiator, and the number that have failed to do so.
A register request is a request for FTAM services sent by the FTAM application
programmatic interface (FTAM API) to the APLMGR process on behalf of an
application. When a user application calls the FTM_INITIALIZE_REQ_ procedure, the
following occurs:
1. API sends a message (register request) to the APLMGR process, requesting the
services of an FTAM initiator process.
2. The APLMGR process checks the status of the next available initiator process.
3. If an initiator is in a state that allows it to accept a request from the APLMGR
process, the APLMGR process issues a message to the initiator process, requesting
that a new subdevice be generated.
4. If the FTAM initiator process responds positively, the APLMGR process sends the
name of the newly generated subdevice back to the FTAM API. If the initiator
responds negatively to the APLMGR request, the APLMGR process repeats Steps 2
and 3 until it receives a positive response from an FTAM initiator process, or until it
has polled all available initiators.
5. The FTAM API opens the selected initiator process directly, using the subdevice
name provided by the APLMGR process, and sends a message requesting an
association through that subdevice.
