This section introduces you to Threshold Manager commands and teaches
you how to get helpful information about them. You
also learn how to review the command line history stack and to
reissue a command you have previously entered, either
as is or with modifications. Overview of Threshold Manager commands |  |
The Threshold Manager commands have the following major functions: to control the Threshold Manager tool to control monitoring of system resources to set threshold configuration
When you enter a command at the Thmgr: prompt,
Threshold Manager validates it, posts it directly to the
configuration file, and sends the command to the
Threshold Manager process if it is active. If it is not active, the
command is saved in the configuration file until you enable Threshold
Manager, at which point it is sent to the process.  |  |  |  |  | NOTE:
All threshold commands are case-insensitive.
All parameters are positional. |  |  |  |  |
The table on the next page briefly explains the commands you
can execute at the Threshold Manager prompt.
You can enter the full command (for example, EXIT) or use the short
version shown in parentheses following the command name (for example, E
in place of EXIT). Table 7-1 Threshold Manager Commands Name | Description |
---|
ADDTHRESHOLD (AT) | Adds a threshold to one of the resources. | DELETETHRESHOLD (DT) | Deletes a threshold from a resource. | DISABLEMANAGER (DM) | Turns off (disables) Threshold Manager. | DISABLENOTIFY (DN) | Suppresses messages at the global level. | DISABLERESOURCE (DR) | Tells Threshold Manager to ignore a
resource and its associated threshold values. | DISPLAY (DP) | Shows the current usage of each resource and the associated
threshold values in a graphic mode. | DO | Allows user to re-execute any command still retained in the
command line history stack. | ENABLEMANAGER (EM) | Turns on (enables) Threshold Manager. | ENABLENOTIFY (EN) | Allows (enables) all notification messages to be
sent to the system console. | ENABLERESOURCE (ER) | Activates the monitoring of a resource. | EXIT (E) | Takes you back to the MPE/iX prompt. | HELP (H) | Provides on-line help about each command. | LISTREDO | Displays the contents of the command line history
stack. | MODIFYINTERVAL (MI) | Changes the time interval between
each operation cycle. | MODIFYTHRESHOLD (MT) | Allows changes on a threshold value,
a control or notification associated with a resource. | REDO | Allows the user to edit and reexecute any command still
retained in the command line history stack. | RESET (RS) | Changes all threshold values to the initial
configuration as delivered with the product. | SHOW (SH) | Displays the configuration file or the configuration
for an individual resource. | USE | Executes a specified file until EOF.
|
To use online help |  |
You can display helpful information about any of the Threshold Manager
commands on the screen. To do so, enter the
HELP command at the Thmgr: prompt in one of two ways: To get help for a specific command, type HELP and then the
command name. For example, to display a description,
the syntax, and examples of the
ADDTHRESHOLD command, enter: To see a list of all the Threshold Manager commands
with a brief description of each one, simply enter
HELP or H.
To reissue a command using DO |  |
Use the DO command to edit and reissue a command held
in the command line history stack. This command functions like the
MPE/iX commands of the same name. You use the DO and REDO commands for the same purpose. The
difference between them is that REDO allows interactive editing of
the command whereas DO requires that you enter the
changes to the command once, as the parameter editstring. The syntax is shown below: DO [CMD=cmdid] [;EDIT=editstring] Parameter | Definition |
---|
cmdid | The command to re-execute. You may specify the command by
its relative or absolute order in the command line history stack, or by
name (as a string) in whole or in part. The default is -1, the most recent command.
Threshold Manager detects an error if cmdid does not exist
in the command line history stack. | editstring | The editing you want performed on cmdid
before Threshold Manager reissues it. If you specify editstring,
it must appear, character forcharacter, and space for space, exactly as it
would if you were using the REDO command in interactive mode.
If you omit editstring, Threshold Manager re-executes the command
immediately, with no changes.
|
You must surround cmdid and editstring by quotation marks
(either " or ') if they contain any delimiters
such as ; " ' [, ], =, or a space. To reissue a command using REDO |  |
Use the REDO command to edit and reissue a command held
in the command line history stack. This command functions like the
MPE/iX command of the same name. You use the DO and REDO commands for the same purpose. The
difference between them is that REDO allows interactive editing of
the command that you want to reissue and DO does not. The syntax is: REDO [ [CMD=]cmdid] [ [;EDIT=]editstring] Parameter | Definition |
---|
cmdid | The command to execute. You may specify the command
by its relative or absolute order in the stack, or by name (as a string).
The default is -1, the most recent command.
| editstring | A string specifying the first of one or more editing
changes to cmdid before the system displays it on your terminal.
You must surround the edit string by quotation marks (" ") if it
contains any scanner/parser delimiters such as: , ; " ' [ ] or = or spaces. After the edited command is displayed, you may continue to
make further changes. When it looks the way you want, enter Return to execute the command. If you omit editstring, you can edit
the command line interactively and then reissue the command. |
For example, to edit the most recent command beginning
with the string “PAS”, you enter REDO MOD.
Or, to edit the second-to-last command on the stack (one command
before the most recent), you enter REDO -2. To review the command line history stack |  |
Use the LISTREDO command to display the contents of
the command line history stack along with an index to
each command. By default, the display order is from the earliest
command to the most recent command. This command functions
like the MPE/iX command of the same name. You can issue this command at the Thmgr: prompt or from a job.
The syntax is: LISTREDO [START=m] [;END=n] [;OUT=outfile] [ ;{[ABS] [REL] [UNN]} ] Parameter | Definition |
---|
START or END | Specifies the range of commands to be displayed. | OUT | Sends the listing to a disk file named outfile instead of
to a terminal. New disk files are created TEMP. File
equations are ignored, unless outfile is preceded by an asterisk
(*). You must use a file equation to overwrite a permanent file.
| ABS | Displays the commands in their absolute order (the order in
which they were entered). ABS is the default.
| REL | Displays the commands in their relative sequence (from -m to
-1), where -1 denotes the most recent command in the stack. | UNN | Suppresses numbering of the commands during display.
|
For example, if there are three commands in the history stack
and the third command is LISTREDO, you will see:
1) COMMANDONE
2) COMMANDTWO
3) LISTREDO
|
To execute a file from Threshold Manager |  |
Use the USE command to execute each line of a specified file
until it reaches the end (EOF). The syntax is: You must specify FileName, which can be the name of any valid
file that you want to execute and to which you have READ access.
For example, to execute a file named myfile, enter:
