The DEFINE /KEY command assigns a string to a keyboard function key.

Note This command is not available in the RTR web browser interface.

Format

DEFINE /KEY key-name "equivalence-string"

Description

This command lets you assign a string to a function key, possibly overriding any predefined function that was bound to that key. When you then press the key, the RTR Utility enters the currently associated string into your command line. The RTR DEFINE /KEY command is similar to the OpenVMS DCL DEFINE /KEY command.

A key definition remains in effect until you redefine the key or exit from the RTR Utility. You can include key definitions in command procedures, for example in the RTR Utility initialization file.

The /IF_STATE qualifier lets you increase the number of key definitions available on your terminal. The same key can be assigned any number as long as each definition is associated with a different state.

By default, the current key state is the DEFAULT state. The current state can be changed by pressing a key that causes a state change (that is, a key that was defined with the DEFINE /KEY /STATE command).

Parameters

key-name

Specifies a function key to be assigned a string. Table 8-21 describes the valid key names.

equivalence-string

Specifies the string to be processed when the specified key is pressed. Typically, this is all or part of an RTR command.

If the string contains spaces or non-alphanumeric characters, it must be enclosed in quotation marks.

Qualifiers

/ECHO (D)

/NOECHO

Controls whether the command line is displayed after the key has been pressed. Do not use /ECHO with /NOTERMINATE.

/IF_STATE=state-name

/NOIF_STATE (D)

Specifies the name of a state to which a key definition applies. /IF_STATE assigns the key definitions to the specified states. A state name can be any appropriate alphanumeric string. /NOIF_STATE (the default) assigns the key definition to the DEFAULT state.

/LOCK_STATE

/NOLOCK_STATE (D)

Controls how long the state set by /SET_STATE remains in effect after the specified key is pressed. /LOCK_STATE causes the state to remain in effect until it is changed explicitly by another function key being pressed that has the /SET_STATE attribute. /NOLOCK_STATE (the default) causes the state to remain in effect only until the next terminator character is typed, or until the next define function key is pressed.

/LOG

/NOLOG (D)

Controls whether a message is displayed indicating that the key definition has been successfully created.

/SET_STATE=state-name

/NOSETSTATE (D)

Controls whether pressing the key changes the current key state. /SET_STATE changes the current state to state-name when you press the key. /NOSET_STATE (the default) causes the current state to remain in effect.

/TERMINATE

/NOTERMINATE (D)

Controls whether the specified string is to be terminated (processed) when the key is pressed. /TERMINATE causes the string to be terminated when the key is pressed. /NOTERMINATE (the default) allows you to press other keys before terminating the string by pressing the [RETURN] key.

• SHOW KEY

Examples

 RTR> DEFINE /KEY PF3 "SHOW RTR" /TERMINATE
 DEFAULT PF3 key has been defined as "SHOW RTR"
 RTR> [PF3]
 
 RTR running on node BE1
 
      

The DEFINE /KEY command defines the [PF3] key on the keypad to perform a SHOW RTR command. DEFAULT refers to the default state.

 RTR> DEFINE /KEY PF1 "HELP " /SET_STATE=GOLD /NOTERMINATE /ECHO
 DEFAULT PF1 key has been defined as "HELP "
 RTR> DEFINE /KEY PF1 " CREATE" /TERMINATE /IF_STATE=GOLD /ECHO
 GOLD PF1 key has been defined as "CREATE"
 RTR> [PF1]
 RTR> HELP [PF1]
 RTR> HELP CREATE
 The "CREATE FACILITY" command is used to ...
      

The first DEFINE /KEY command defines the [PF1] key to be the string HELP. The state is set to GOLD for the subsequent key. The /NOTERMINATE qualifier instructs the system to remain in command input mode when the key is pressed. The second DEFINE /KEY command defines the use of the [PF1] key when the keypad is in the GOLD state. When the keypad is in the GOLD state, pressing [PF1] will cause the current read to be terminated.

If you press [PF1] twice, the system displays and processes the HELP CREATE command.

The word DEFAULT in the second line of the example refers to the fact that [PF1] has been defined in the default state. Note the space before the word CREATE in the second DEFINE /KEY command. If the space is omitted, the system fails to recognize CREATE as the keyword for the HELP command.

The DELETE FACILITY command deletes an RTR facility.

Format

DELETE FACILITY facility_name

Description

The DELETE FACILITY command removes the specified facility on the node where the command is issued. After issuing this command, applications are no longer able to use the facility. Any outstanding transactions using the facility are aborted.

Parameters

facility_name

The name of the facility to delete.

The parameter facility_name must be supplied.

Qualifiers

/CLUSTER

/NOCLUSTER (D)

The DISPLAY BAR command displays a bar graph in a monitor picture.

Note This command is not available in the RTR web browser interface.

Format

DISPLAY BAR expression

Description

The DISPLAY BAR command displays the expression as a bar graph in a monitor picture. It can be used within a monitor file or issued at the RTR prompt when interactively defining a monitor picture for use in a subsequent MONITOR command.

Note that the introduction of the /SEPARATE, /TOTALIZE and /AVERAGE qualifiers has superseded the qualifiers /FACILITY, /LINK, /PARTITION, /NODE and /PROCESS. These superseded qualifiers are no longer described here, however they are still supported. Chapter 7 and Appendix A contain more information on monitor pictures and monitor files.

Parameters

expression

Specifies the quantity to be displayed. Expression can be either the name of a single data item or an expression combining several items using simple arithmetic operations and constants. In the latter case, expression must be in quotes.

Qualifiers

/AVERAGE=(keyword,...)

/NOAVERAGE

Specifies that the items being monitored relating to keyword are displayed as an average. This allows a number of items to be averaged in one qualifier.

The keyword can be one of the following:

Keyword	Meaning
NODE	Node data items
LINK	Link data items
FACILITY	Facility data items
PROCESS	Process data items
PARTITION	Partition data items
FE_TRANSACTION	Frontend transaction data items
TR_TRANSACTION	Router transaction data items
BE_TRANSACTION	Backend transaction data items

/BELL[=Boolean-expression]

/NOBELL (D)

Sends a bell character to the terminal if Boolean-expression evaluates to True (non-zero).

/BLINK[=Boolean-expression]

/NOBLINK (D)

Specifies that the displayed value blinks if Boolean-expression evaluates to True (non-zero).

/BLANK[=Boolean-expression]

/NOBLANK (D)

Specifies that the displayed value is replaced by blanks if Boolean-expression evaluates to True (non-zero).

/BOLD[=Boolean-expression]

/NOBOLD (D)

Specifies that the item is displayed in high intensity if Boolean-expression evaluates to True (non-zero).

/CHARACTER[=char]

/NOCHARACTER

/CHARACTER="a" (D)

Specifies the character used to draw bar charts. The line drawing character set is used to display them. By default, the character "a" is used, which corresponds to a rectangular block in the character set. If /NOCHARACTER is given, no characters are displayed and the bar is visible only if attributes have been specified. This can be used to draw a scale behind the bar chart.

/COLSPAN=n

/COLSPAN=1 (D)

Specifies the number of columns the item is to span in the HTML table where it is displayed. The default is one column.

/DAMPING[=damping-factor]

/NODAMPING (D)

Specifies that the value displayed is to fluctuate more slowly than the raw measured value. The default for damping-factor is one. Damping is only relevant if /VALUE=CURRENT .

/DESCRIPTION="text-string"

Provides a descriptive text for the item being displayed. Column headers are often cryptic as little room is available. The browser will display the descriptive text in a popup window (currently, Internet Explorer only).

/DISPLAY

Specifies that text formatting is to be suppressed if the /NOTEXT qualifier is chosen, so that HTML output is easier to read. Use the /NOHTML qualifier if you only want text as output. By default, items are displayed in both text and HTML views.

/HEADER

/NOHEADER (D)

Indicates the item is part of a table header. This qualifier should be attached to the first item of a new row.

/LABEL=text

/NOLABEL (D)

Specifies the text used to label the value being displayed. Symbols are substituted at display time. (See Section A.2, Substitution Symbols).

/LENGTH[=nr-chars]

/LENGTH=50 (D)

Specifies the number of characters in a bar chart representing the maximum value. The default is 50.

/MAXIMUM[=max-value]

/MAXIMUM=10 (D)

Specifies the maximum value represented on a bar chart. The default is 10.

/MINIMUM[=min-value]

/MINIMUM=0 (D)

Specifies the minimum value represented on a bar chart. The default is zero.

/PARAGRAPH

Causes a display item to be formatted as the first item of a new paragraph in the HTML output. This qualifier is effective only while in text mode, after the /NOTABLE qualifier has been used.

/RATE[=interval]

/NORATE (D)

Specifies that the rate of change of the expression is to be displayed rather than the absolute value. When /RATE is used, interval specifies the time interval in seconds used to calculate the rate of change. This has no effect on the sampling; it simply allows the rate to be displayed in another unit. For example, displaying the start transaction counter with /RATE=60 results in transactions per minute being displayed instead of per second.

/REVERSE[=Boolean-expression]

/NOREVERSE (D)

Specifies that the item is displayed with the foreground and background visual attributes swapped if Boolean-expression evaluates to True (non-zero).

/ROWS[=nr-rows]

/ROWS=1 (D)

Specifies how many rows are used to display the item. This is only meaningful if /SEPARATE is also specified. The default number of rows is one.

/SELECT[=Boolean-expression]

/NOSELECT (D)

Displays the item if Boolean-expression evaluates to True (non-zero).

/SEPARATE=(keyword,...)

/NOSEPARATE

Specifies that the items being monitored relating to keyword are separated from each other and displayed as a list. This allows a number of items to be separated in one qualifier.

The keyword can be one of the following:

Keyword	Meaning
NODE	Node data items
LINK	Link data items
FACILITY	Facility data items
PROCESS	Process data items
PARTITION	Partition data items
FE_TRANSACTION	Frontend transaction data items
TR_TRANSACTION	Router transaction data items
BE_TRANSACTION	Backend transaction data items

/TABLE

/NOTABLE

Indicates the start of a new table in the monitor output. This qualifier should be attached to the first item of a new row. Specifying /NOTABLE causes any current table to be closed and a new text section to be started in the HTML output.

/TOTALIZE=(keyword,...)

/NOTOTALIZE

Specifies that the items being monitored relating to keyword are added together and displayed as a total.

The keyword can be any of the following:

Keyword	Meaning
NODE	Node data items
LINK	Link data items
FACILITY	Facility data items
PROCESS	Process data items
PARTITION	Partition data items
FE_TRANSACTION	Frontend transaction data items
TR_TRANSACTION	Router transaction data items
BE_TRANSACTION	Backend transaction data items

/UNDERLINE[=Boolean-expression]

/NOUNDERLINE (D)

Specifies that the displayed value is underlined if Boolean-expression evaluates to True (non-zero).

/VALUE[=value-type]

/VALUE=CURRENT (D)

Specifies how the value is processed before being displayed. Value-type can be one of the following keywords:

CURRENT	(default) Displays the current value of expression
AVERAGE	Displays the average value of expression since the MONITOR command was issued
MINIMUM	Displays the minimum value of expression since the MONITOR command was issued
MAXIMUM	Displays the maximum value of expression since the MONITOR command was issued
