Controlling the format of messages and status information on console screens z/OS MVS Planning: Operations SA23-1390-00 |
|
On a display console, a message can appear by itself or with information about the message, such as job and system identification and the time the message was issued. In a status display, information about when jobs start or stop, when a data set is freed, or information about TSO/E user sessions can appear. Also, mount messages in status displays can contain specific information about mounting volumes. You can control the information for messages or status displays that operators view on the console screen. Controlling message formats can help free up screen space or make it easier for operators to read messages. Controlling status information can help operators monitor workload or handle job allocation that requires mounting requests. Use the following keyword and its options on the CONSOLE statement
to control information about messages for display:
Options you can specify for MFORM are as follows:
How messages are displayed on the screen can affect your operations.
Consider eliminating information from displayed messages when:
To request that the system add a time stamp, the name of the system
that issued the message, and the job name or id of its issuer, code
the following on the CONSOLE statement:
Operators can also use the CONTROL S command to make these same
changes. The format of a message that includes information in the
previous example is:
MCS, HMCS or SMCS console display Defining the X option for an MCS, HMCS or SMCS console allows you to suppress the system name and jobname for JES3 messages that are issued from the global processor when those messages appear on the MCS, HMCS or SMCS console screen. For example, to suppress both jobname and system name for JES3
messages issued on the global processor, code the following MFORM
values on the CONSOLE statement for the MCS console:
For an HMCS console, devnum must be HMCS. For an SMCS console, devnum must be SMCS. Displaying system names in a sysplex In a sysplex, the number of characters displayed on the console screen for system name depends on the longest name of the system that joins the sysplex. If SYSB is the longest name, all system names will be four characters. If SYB is the longest name, all system names will be three characters. For example, if three systems in a sysplex are named SYS1, SY2,
and S3, the displayed messages from any system will have a four character
system name:
If a system with longer name joins the sysplex, the length of the system name in the messages is adjusted to accommodate the new name. For consistency, you might want to use system names of the same character length. DISPLAY R, CONTROL S, and MFORM Operators can issue the DISPLAY R command with MFORM options to
retrieve information about messages awaiting action. In a sysplex,
if the operator issues DISPLAY R without MFORM, the format of the
messages depends on how MFORM has been specified for CONSOLxx or on
the CONTROL S command:
For JES3 multisystem environments, when DISPLAY R is issued without MFORM, the system uses the S option as a default. |
