DEFINITIONS AND GENERAL FUNCTIONS
Wildcard characters (* or %) may be used in character strings at almost all places.
The VIP output can be written into a file. The default output is written to SYS$OUTPUT.
With the definition of the next logical names you can influence the VIP input and output:
- VIP$INIT : Points to the VIP initialization command file.
- VIP$INPUT : Points to the VIP input command file. The default is SYS$INPUT.
- VIP$OUTPUT : Points to the VIP output file. The default is SYS$OUTPUT.
With the @-character you can execute VIP command files. The command VIP @MY_COMMANDS reads all
VIP commands in file MY_COMMANDS.VIP and executes them.
All VIP monitor commands can define the interval period and the beginning and ending time. Besides an
automatic interval, VIP also has a manual interval.
Some VIP commands can:
| 1: |
perform a REPLY, which sends a user defined broadcast message to the terminal of a process.
|
| 2: |
perform an ACTION on a process, which can be to stop a process, modify the Process Priority or
suspend or resume a process.
|
| 3: |
perform a REFRESH (automatic or manual), because selection of objects (disk devices or processes)
against the specified selection criteria will take place at the beginning of a VIP monitor command only.
Only the objects that are found at the beginning will be monitored. With the use of REFRESH objects
are selected again. This way newly created processes will be selected and deleted processes will be
removed.
|
| 4: |
activate an ALARM. The conditions to activate an ALARM are different for each monitor command. The
use of ALARM allows you to:
- define the repetition count of an alarm message (default 1).
- define the number of consecutive interval periods with an alarm condition before an alarm
message will be generated or repeated (default 1 interval period).
- store alarm messages in a file.
- send alarm messages to the operator console terminal.
- send alarm messages to a list of mail addresses. If SMTP mail has been configured, alarm
messages may also be sent as e-mail messages over the internet.
- send alarm messages to a list of processes, users or terminals.
- define the position of the alarm messages on the screen and their video attributes.
|
| 5: |
perform a SUBMIT if the ALARM has been activated. A batch job will be started which allows you to
perform any nessecelary actions to reset the alarm condition. The SUBMIT can be provided with a
number of parameters, such as the starting time of the batch job, the name of the command
procedure to be executed in the batch job, the name of the batch job, the name of the batch job log
file, indication for notification when the batch job ends, priority of the batch job, name of the batch
queue and the username under which the batch job will be executed. Parameters P1 up to P4 of the
executed command procedure will be filled by the monitor command, parameters P5 up to P8 are free
to be used.

To prevent that the execution of a VIP command will be interrupted by broadcast messages of mail, batch
jobs, replies, etc., you can disable the broadcast for any class. When you stop VIP, the previous
broadcast settings will be reset. Click here to see the online help of how to change
the broadcast settings.
To retrieve the correct information on busy systems with a VIP monitor function at accurate interval
periods or to display information without placing the VIP process in a wait state, you can temporaryly
increase the Process Priority of the VIP process. When you stop VIP, the previous Process Priority will be
reset. Click here to see the online help of how to change to Process Priority.
Selection of processes on another node in an OpenVMS cluster and the selection of remote mounted disk
devices can only be performed when a VIP Cluster License has been loaded.
