The databases monitored by Adabas Review are considered to be target objects. The monitored databases and the hub are running on an Adabas SVC or router.
A target object is defined to Adabas Review in a target definition using the ET command. A target definition provides Adabas Review with the essential characteristics of the object to be monitored.
Adabas Review uses the target definition of Adabas targets to generate INPUT cards for the Adabas Review processor. For the Adabas Review hub, you must specify the target ID of the hub.
If a target definition cannot be found, the INPUT cards are generated using the definition of the default target (that is, target ID 00000).
If the default target cannot be found, Adabas Review generates the INPUT cards using internal defaults.
Adabas Review provides three commands for SVCs and target objects:
Code | Function | Action |
---|---|---|
AA | Adabas Availability | Lists target objects for a particular SVC as well as session statistics. |
AH | Available Hubs | Lists available Adabas Review hubs |
ET | Edit Target Definitions | Used to create target definitions. |
LT | List Target Definitions | Lists existing target definitions. |
This document covers the following topics:
The Adabas Availability (AA) subsystem displays available targets associated with an Adabas supervisor call (SVC). Adabas Review maintains a list of possible SVC numbers as part of its target definition subsystem.
This section covers the following topics:
To access a list of all the active Adabas SVCs known to Adabas Review:
Enter the AA code on any command line.

The Active Adabas SVCs screen appears, where, for z/OS, the SVC is the supervisor call (SVC) number used for communications with the target object. The number of target objects assigned to that SVC is listed in the associated Num Targs field.
Note:
In CICS environments, only the one SVC that is in the
link routine appears on this screen.
To display a list of all targets known to a particular SVC number:
Mark an SVC on the Active Adabas SVCs screen with an "X", and press ENTER.
The Available Targets screen appears, listing targets using the selected SVC for communication. Scroll keys are provided. If more than one screen of objects exists, PF8 (+) scrolls the list forward and PF7 (-) scrolls the list backward.
Note:
The list of targets on this screen is the result of a
direct query to the SVC and includes inactive targets and non-Adabas databases
using that SVC. The list is sorted by the DBID.

The Adabas Availability (AH) subsystem displays available Adabas Review hubs associated with an Adabas supervisor call (SVC).
This function only displays the available Adabas Review hubs which run on the default SVC that is specified in the ADALNK routine.
To access a list of all the Adabas Review hubs:
Enter the AH
command on any
command line.
A pop-up screen listing the available hubs on the selected SVC appears.

To select a hub, type any character next to the hub of your choice on the pop-up window and press ENTER. Then press PF3 to exit the pop-up window.
Target definitions are usually edited by the Adabas Review administrator because changes to database targets affect all users of Adabas Review.
Target definitions can be created, edited, listed, and purged. If target information is changed it will not immediately apply to the Adabas Review system. After the new parameter setting is saved into the Adabas Review repository file, it is also written to data sets identified by the RVUAUT1 and RVUAUT2 job control statements. When Adabas Review is next restarted, the new session parameters will apply.
If you are running in hub mode, the target ID of the Adabas Review hub must be specified and the parameter setting will be written to the data sets specified by the Adabas Review hub.
Note:
When using the online interface to maintain target definitions,
only one target entry can be specified for each DBID, even if there are
multiple SVCs with the same DBID.
To access the Edit Target screen:
Enter the ET command on the command line and press ENTER.
The Edit Target screen appears as shown below:

The Edit Target screen displays three categories of input fields:
Database Parameters to describe characteristics of the database;
Numeric Delimiters to control record and buffer segment sizes; and
Logging Options.
The Adabas Review intermediate buffer is used as a staging area to pass the command log records between the Adabas Review subtask and the attached Adabas Review processor in local mode, or between the Adabas Review client and server in hub mode. The parameter BUFFMB in the Adabas Review INPUT statement controls the size allocation. The values for these parameters are obtained from the database target definition.
The following table provides more detailed information about the input fields on the Edit Target screen. Default values are underlined.
Field | Value | Description |
---|---|---|
Buffer Size | nnnnn | 10 | Defines the size of the Adabas Review buffer pool in MB. The minimum value is 1. |
The List Target Definitions (LT) command displays the existing target definitions that were created using the Edit Target (ET) command.
To display a list of target definitions
Enter the code LT on the command line and press ENTER.
The Target Definitions screen appears, similar to the one shown below:
21:10:29 A D A B A S - R E V I E W 2020-03-20 REVIEW-DB (10,252) Target Definitions Hub Target: 296 Review 64-Bit Sel DBID Target Name Ver SVC Commands zIIP Buffer Mode +-----------------------------------------------------------------------------+ | __ 00000 DEFAULT TARGET 841 249 Y N N V52 | | __ 00299 QEHUB299 000 249 Y N N V51 | | | | | | | | | | | | | | | | | | | | | +-----------------------------------------------------------------------------+ Command: ______________________________________________________________________ Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12--- Help Exit - + Menu |
The fields on the Target Definitions screen describe the targets as they are defined to the system. The following table describes the fields:
Field | Description |
---|---|
DBID | The database ID of the target object. |
Target Name | The name assigned to the target by the user. |
Ver | The version, revision, and system maintenance level of the target. |
SVC | The number of the SVC used to communicate with the target. |
Review Commands | Local mode only. Indicates whether the Adabas Review command processor includes commands issued by the Adabas Review online system in its reports. This is used if the Adabas Review processor is running as an Adabas subtask; that is, not in batch. |
zIIP | Indicates whether Adabas Review target is defined with (ZIIP=YES) or without zIIP parameter (ZIIP=NO). |
64-Bit Buffer | Indicates whether Adabas Review makes use of 64-bit addressable storage or not. |
Mode | Indicates whether the new, version 5.2 handling of command log extensions of a record is used (default), or the old version 5.1 (or below) handling. |
You may edit or purge target definitions from the Target Definitions screen.
To display the commands available for use from this screen
Enter a ? on the selection line preceding a target definition and press ENTER.
To edit an existing target definition:
Enter the ET command on the selection line preceding the target definition and press ENTER.
The Edit Target screen for that particular target is displayed.
Modify the definition by typing over the existing information.
Either press PF5 or enter SAVE on the command line and press ENTER.
Note:
After the definition is saved in the Adabas Review
repository file, it is also written to the data sets identified by the RVUAUT1
and RVUAUT2 job control statements. However, the changed target information is
not immediately available to the Adabas Review system. When Adabas Review is
next restarted, any changed definitions are applied at that time to the
system.
Target definitions may be deleted using the PURGE command.
To delete a target definition
Enter the PT command on the selection line preceding the target definition and press ENTER.
Depending on your user profile, you may or may not be prompted to confirm the purge request.
Note:
After the definition is purged in the Adabas Review
repository file, it is also purged from the data sets identified by the RVUAUT1
and RVUAUT2 job control statements. However, the purged target information will
continue to appear to be available to the Adabas Review system until Adabas
Review is next restarted. When Adabas Review is restarted, any changes (or
deletions) to the target definitions are applied to the system.
