Display data space information

The holder task allocates and manages a common access data space (CADS). The following command displays the information in this data space:

F <holder>,DISPLAY,DSP,{FORMAT|DUMP}

In order to use this command, the holder task must contain DD statement

//DSPPRT   DD  SYSOUT=*,LRECL=255

The output for this display command is written to DSPPRT. If necessary, one needs to scroll to the extreme right to see the full output.

Sub parameter DUMP writes the unformatted storage areas from the data space, when using the keyword FORMAT the information is written in human readable form. Below is one example user entry:

Userid   JobName  JobId    SYS  Port  L F1 F2 F3 F4 F5 JP  CRP  
--------------------------------------------------------------

mm/dd hh:mm:ss Modify  07/22 hh:mm:ss mm/dd hh:mm:ss

Column JOBID contains a valid JESx job ID when a user server is running and listening on the port specified in column PORT. The (not valid) JESx job ID of STCTIMEO is set either when a user server had terminated (for instance due to inactivity - timeout) or when a client logged on but did not need to start a user server yet. This is called deferred logon. Once the client requests a service that can only run in a user server, that user server is "restarted" using the indicated port.
