The ADM (Automatic Display Mode) command lets you start or stop automatic display of current system status information on the same ODT at which the ADM command is entered. ADM settings can be changed at any time from the ODT. Automatic display is useful for monitoring the status of scheduled and completed entries, jobs in the mix, libraries, database stacks, peripheral units such as line printers, queue settings, messages from the operating system, and other automatic display information.

Two different modes exist: event-driven automatic display mode (ADM) and time-driven ADM. With event-driven ADM, any new event for which an option has been specified is automatically reflected in the updated display. The default delay time for event-driven ADM is 10 seconds. Time-driven ADM updates its display at specified intervals.

Explanation

ADM

Displays the current ADM options under which the ODT is operating. If ADM is canceled, this command sets up ADM with the following default options:

ADM (A7, W3, S2, C5, MSG) DELAY 4.

ADM −

Cancels ADM. Any options set up for the ODT are discarded and the default setting is used for all subsequent initiations of the ADM command.

ADM ST

Stops ADM. ADM instructions are retained but are not executed.

ADM OK

ADM GO

Resume ADM. OK is used after ADM ST, and also to restart ADM after a program has opened a file that the system has assigned to that ODT and is still using it.

ADM (<timed options>)

If the first item following ADM is a left parenthesis, ADM unconditionally displays the described pages after the specified time interval. In the time-driven mode, each group of timed options enclosed in parentheses specifies one page of an ADM display. Each page is automatically updated and displayed after the interval specified by DELAY.

You can specify multiple pages of time-driven ADM by entering more than one group of timed options enclosed in parentheses. The display rotates from one page to the next.

Information for the MSG (Display Messages) option is restricted to a maximum of 42 lines of messages, regardless of the number of lines specified.

A list of the items that can be displayed as timed options follows. The syntax for each option except PS is the same as for its system command counterpart.

ADM + (<timed options>)

Adds the new ADM instruction to the current ADM specification, which must be a time-driven ADM.

<number>

The number in the timed options syntax diagram specifies the number of lines to allow for each item displayed. Two or more lines must be specified for each category because the heading occupies one line. Lines need not be specified for the last entry on a page; if lines are not specified, that entry fills the rest of the page. For ASD (Actual Segment Descriptor), CU (Core Usage), O (Overlay), PS (Print System status), and U (System Utilization) options, the complete information is displayed regardless of the value specified for the number. If there are insufficient lines available on the page, the excess information is discarded.

DELAY <number>

Specifies the number of seconds of delay before the next ADM page is to be displayed.

ADM EVENT

If the first syntactical item following ADM is the word EVENT, the system automatically updates the appropriate screen display when a change occurs in the status of one of the named displays. For example, if the command ADM EVENT W is entered, the waiting mix list page is displayed whenever the system stops a task requiring operator attention. No matter how frequently events occur, messages are displayed only at intervals of DELAY <number> seconds, or 10-second intervals if no DELAY is specified. EVENT options are as follows.

ADM + EVENT

Adds the new ADM instruction to the current ADM specification, which must be for event-driven ADM.

<mix display option>

Specifies the entries that are eligible for inclusion in the ADM display. The possible options are as follows.
