Operator Commands

Note:
The commands described in this section of the documentation are used only in hub mode.

The operator commands in this section of the documentation are used to control Adabas Review (ADAREV). They perform the following general types of operations:

This document covers the following topics:


Entering Operator Commands

Start of instruction setTo enter ADAREV operator commands in z/VSE environments

  1. Enter an MSG command for the z/VSE partition in which Adabas is executing (for example, MSG Fn).

    Adabas responds when ready for communication with Adabas message ADAI29. In cases where the commands ADAEND and CANCEL cause Adabas to end the nucleus session, no outstanding reply is presented so that an orderly shutdown can occur without the need for operator intervention.

  2. Enter the desired Adabas operator command or commands.

    More than one command can be entered in a session. You can also enter a command followed directly by a slash (/) to end any further operator communications until the next MSG command by z/VSE.

  3. When all desired commands have been entered, close the operator communication session by entering a null command (EOB).

  4. To enter any more commands after the session is closed, repeat this entire procedure.

Operator Command Overview

The remainder of the section describes the commands that an Adabas Review operator can enter from the console.

ADAEND Operator Command

Use the ADAEND operator command to terminate an ADAREV session normally; the Adabas Review nucleus is terminated normally. No new monitoring commands are accepted and all currently queued requests are dropped.

CANCEL Operator Command

Use the CANCEL operator command to terminate ADAREV immediately; the Adabas Review nucleus is abnormally terminated and the job aborts with a user completion code of 253.

DCLIENT Operator Command

Use the DCLIENT operator command to display information about the specified client or about all (ALL) clients. DCLIENT displays the number of clients currently registered with the hub and the individual status of each client, including the client's DBID, the associated nucleus IDs (for cluster databases), the time of last activity, the number of DBID=ALL reports, the number of database reports, any buffers required by the client, and the total number of monitoring data records received from the client. The following is an example of the message output:

REVH13 11135 Dbid Nucid Last-act Rpts Buffers Log-records
REVH13 11135 00001       22:15:18 01/01 FRSVIM 2222
REVH13 11135 00002       --:--:-- 01/00 ------ 0
REVH13 11135 00129       --:--:-- 01/02 -R---- 0
REVH13 11135 00129-00120 22:15:18 00/00 ------ 1
REVH13 11135 00129-00177 22:15:20 00/00 ------ 170
REVH13 11135 00129-00230 --:--:-- 00/00 ------ 0

In this example:

DCQ Operator Command

Use the DCQ command to display the entire list of queued requests. The DCQ displays the sequence number, client's job name, client's user ID, request code, and status flags for each queued request.

Note:
If a large value was set for NC (as is recommended), the DCQ request may incur delays in the Adabas Review hub processing if a large number of queue elements must be displayed. Also, the display on the operator console may fill the console's buffers causing further system delays.

The following is an example of the message output:

AREV07 hubid  0000000013 NEXT EXPECTED SEQUENCE NUMBER
AREV07 hubid  0000000011 ADASMP    ARVU D   (C1D9E5E400C40000)  PC 2800
AREV07 hubid  0000000012 ADASMP    ARVU D   (C1D9E5E400C40000)  PC 2800  

DNC Operator Command

Use the DNC operator command to display the number of queued requests currently in the command queue.

STARTCLIENT Operator Command

Use the STARTCLIENT operator command to initiate a change order command to the specified client or to all (ALL) clients informing them to begin sending monitoring data to the hub. The change order is only sent to registered clients (clients that appear on the DCLIENT operator command display).

Note:
A change order changes a client's operation only if the monitoring status has been changed. This occurs only in cases where a previous STOPCLIENT operator command had been issued.

STOPCLIENT Operator Command

graphics/review_stopclient.png

Use the STOPCLIENT operator command to initiate a change order command to the specified client or to all (ALL) clients informing them to stop sending monitoring data. The change order is only sent to registered clients (clients that appear on the DCLIENT operator command display).

Adabas Operator Commands

The following operator commands can be entered to monitor and control Adabas nucleus operation.

ADAEND

Terminates the Adabas session normally. No new users are accepted after this command has been issued. ET logic updating continues until the end of the current logical transaction for each user. After all activity has been completed as described above, the Adabas session is terminated.

CANCEL

Terminates the Adabas session immediately. All command processing is immediately suspended. A pending AUTORESTART is in effect, which in turn causes the AUTORESTART routine to be executed during the initialization of the next Adabas session.
