H.4.2.21 VECTOR Class Record - VAX Only

The VECTOR class record contains data describing the time during which vector consumers have been scheduled on a vector-present processor. Its record type number is 23. A VECTOR class record is of variable length and depends on the number of active processors in the system. Assuming all processors are active, MONITOR calculates the size of the record by adding the size of the class header, the class prefix, and the data blocks contained in the record. This is shown in the following formula:

13 + 8 + (5 * MNR_SYI$B_VPCPUS)

Figure H-33 illustrates the format of the VECTOR class record.

Figure H-33 VECTOR Class Record Format - VAX Only

The following table describes the contents of each of the VECTOR class record fields:

Field	Symbolic Offset	Contents
CPU ID	MNR_VEC$B_CPUID	Identification of the processor from which the data has been collected (byte, I)
Ticks	MNR_VEC$L_TICKS	Number of 10-millisecond clock ticks in which a vector consumer has been scheduled on this processor (longword, C)

To support the VECTOR class, MONITOR uses the items MNR_SYI$B_VPCPUS and MNR_SYI$L_VPCONF in the system information record. See the table in Section H.3.2 for details on these items.

Appendix I
SHOW CLUSTER Keypad Commands

SHOW CLUSTER provides a predefined keypad that you can use to enter selected commands. You can add, remove, or reposition windows, scroll their contents, or change the interval at which the display is updated. You can also customize the keypad by redefining the default functions of individual keys.

I.1 Using the Keypad

By default, the numeric keypad is defined as shown in Figure I-1.

Figure I-1 SHOW CLUSTER Default Keypad

Shading over a keypad command indicates that you must press the GOLD key and then the keypad key.

The following table describes each keypad command you can use with the Show Cluster utility. In this table, KPn refers to the keypad key labeled with the number n. For example, KP2 refers to the keypad key labeled with the number 2. All commands shown on the keypad are also discussed in the Command Section of Chapter 19.

Command	Key or Key Sequence	Description
ADD	KP4	Modifies the current display by including the field or class that you specify after the ADD command.
DESELECT	GOLD-Period	Terminates a window selection.
GOLD	PF1	When pressed before another keypad key, specifies the second key's alternate function (the bottom function on the keypad diagram).
HELP	PF2	Displays information about using the editing keypad.
INIT	PF4	Resets the display using the original default values for field names, class names, and field widths.
REFRESH	PF3	Refreshes the screen display. Clears and redraws the screen, deleting any extraneous characters or messages that might have appeared on the screen but are not part of the SHOW CLUSTER display. (Performs the same function as Ctrl/W.)
REMOVE	KP5	Modifies the current display by removing the field or class that you specify after the REMOVE command.
SAVE	KP2	Allows you to save the current display to a startup initialization file or a command procedure that you can then use to restore the display at a later time.
SELECT	Period	Designates which window to scroll or move.
SET	KP1	Changes any of several options including the number of columns in the display, the number of seconds between updates, the functions of the arrow keys, the auto positioning of windows, and the characteristics of a particular field.
SET AUTO_POS OFF	KP6	Disables the automatic positioning of windows on the screen.
SET AUTO_POS ON	GOLD-KP6	Enables the Show Cluster utility to automatically position windows on the screen. This is the default setting.
SET FUNCTION EDIT	Hyphen	Redefines the arrow keys to restore line-mode editing.
SET FUNCTION MOVE	KP9	Redefines the arrow keys to move a selected window to a specified position on the display screen. For example, the UP, DOWN, RIGHT, and LEFT arrow keys are redefined as MOVE UP 1, MOVE DOWN 1, MOVE RIGHT 1, and MOVE LEFT 1, respectively.
SET FUNCTION PAN	KP7	Redefines the arrow keys to rotate the display. For example, the UP, DOWN, RIGHT, and LEFT arrow keys are redefined as PAN UP 1, PAN DOWN 1, PAN RIGHT 1, and PAN LEFT 1, respectively.
SET FUNCTION SCROLL	KP8	Resets the arrow keys to scroll the screen display. For example, if you press the SET FUNCTION SCROLL key, the UP, DOWN, RIGHT, and LEFT arrow keys are redefined as SCROLL UP 1, SCROLL DOWN 1, SCROLL RIGHT 1, and SCROLL LEFT 1, respectively.
WRITE	KP3	Outputs the current display to either a file name that you specify, or to the default output file name SHOW_CLUSTER.LIS.

I.2 Redefining the Keypad Keys

Use the DEFINE/KEY command to change the definition of a key. See the DEFINE/KEY command in the Command Section of Chapter 19 for more information.

I.3 Redefining the Arrow Keys

By default, the SHOW CLUSTER arrow keys are set to the EDIT function. This means that you can perform command line editing at the command prompt that is similar to DCL line-mode editing. For example, the left arrow key moves the cursor to the left, or the up arrow key recalls the previous command. See the OpenVMS User's Manual for information about DCL line-mode editing.

The SET FUNCTION keys, shown in the second row of the keypad, redefine the arrow keys to perform a specified function. You can reset the arrow keys from EDIT to PAN, SCROLL, or MOVE with the SET FUNCTION command. For example, if you press the SET FUNCTION SCROLL key, the up, down, right, and left arrow keys are redefined as SCROLL UP 1, SCROLL DOWN 1, SCROLL RIGHT 1, and SCROLL LEFT 1, respectively. (See the Command Section of Chapter 19 for information about specific commands.)

Note

If you set the function to PAN, SCROLL, or MOVE, the arrow keys are no longer defined to perform DCL line-mode editing. Only one function can be enabled at a time. To restore line-mode editing once it has been changed to another function, enter the command SET FUNCTION EDIT.
