Command types

There are four types of commands that are used in OMEGAMON® for IMS.

The following figure shows the four types of commands and sample output.

The types of commands include the following:

INFO-line

These commands perform control functions such as printing a screen (/PRINT) and stopping your session (/STOP).

INFO-line commands are executed first and disappear as soon as they execute. Therefore, you cannot save them in a screen space. INFO-line commands always begin with a slash (/) and must be entered on the top line (starting in column 2).

Note: If you are running in an automatic update mode, placing the cursor in column 1 on the top line pauses updating until you move the cursor.

Major

These commands select general categories for display, such as system information, resource utilization, or storage utilization. In the example, the major command DISK produces a list of online disks. You can enter major commands on any line after the INFO-line.

Minor

These commands display detailed information about the category that the major selects. In the example, the minor command DADR displays the unit addresses of the devices listed with DISK. You can enter minor commands on any line after the INFO-line, but they do not execute unless they are preceded by an appropriate major command.

Immediate

These commands serve various functions. Some are system monitoring commands, while others provide information about your session or about OMEGAMON for IMS.

In the example, .MIN produces a list of all the minors of DISK. Immediate commands can also provide screen and session controls, and often perform the same or similar functions as INFO-line commands of the same name. You can include control commands as part of a screen space.

Enter immediate commands on any line after the INFO-line. You can enter immediate commands between a major command and one of its minors.
