Using Threshold Manager Commands
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).

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:
Thmgr:HELP ADDTHRESHOLD
* 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:
[ {ABS}]
LISTREDO [START=m][;END=n][;OUT=outfile][;{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:
USE {FileName}
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:
Thmgr:USE myfile
