Display detail status
D(ISPLAY) T(ASK = (T|D|W|S)nnn
This request is used to produce a detailed display of the status of the DB2
Manager control region retrieval configuration. The DISPLAY command may
be abbreviated to the single character 'D'. The TASK parameter may be
abbreviated to the single character 'T'. 'nnn' is the numeric identifier of the
task to be displayed (where ‘nnn’ consists of 1-3 numeric characters in the
range 1-256). This should be preceded by the character ‘T’ for a tape reader
task, ‘D’ for a disk reader task, ‘W’ for a writer task and ‘S’ for a scheduler
task. If omitted, a default entry of ‘T’ will be used. This entry must be a valid
task number, as displayed via a summary status display request.
A detail status request will first of all display message OTD20063 for the
identified task. For busy tasks with a non-zero queue length, a detail status
request will display one set of OTD20066 and OTD20067 messages for each
request in the queue. These messages will display the following fields:
