Displaying SVC Lists and Target Objects

The databases monitored by Adabas Review are considered to be target objects. The monitored databases and the hub are running on an Adabas SVC.

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 Adabas Review reports that are autostarted (that is, started automatically when the database is initialized) or run in batch mode.

Adabas Review provides three commands for SVCs and target objects:

Code Function Action
AA Adabas Availability Lists target objects for a particular SVC.
ET Edit Target Definitions Used to create target definitions.
LT List Target Definitions Lists existing target definitions.

This document covers the following topics:


Using the Adabas Availability Function

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.

Note:
For BS2000 operating systems, this function is not yet available.

This section covers the following topics:

Accessing the SVC List

Displaying Adabas Nucleus Session Statistics

Start of instruction setTo display statistics regarding an Adabas nucleus session:

  1. Mark an SVC on the Available SVCs screen with an "X", and press ENTER.

    The Available Targets screen appears, listing targets using the 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.

  2. Mark an Adabas database target on the Available Targets screen with an "X", and press ENTER.

    If a non-Adabas target is selected, an error message appears.

    If an Adabas target is selected, the Adabas Availability screen appears displaying statistics about the Adabas nucleus session.

Creating a Target Definition

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.

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.

Start of instruction setTo access the Edit Target screen:

  1. 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:

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 parameters BUFFERS-4K and BUFFERS-32K in the Adabas Review INPUT statement control the size allocation. The value 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.

Database Parameters

Field Value Description
Target DBID (required) nnnnn The database ID of the target object. There is no default value.
Target SVC (required) nnn | 000 The number of the SVC used to communicate with the target.
Target Version nnn | 000 The version, release, and system maintenance level of the target. For example, for Adabas version 7.4.1, this field would contain the value 741.

Numeric Delimiters

Field Value Description
Buffers-4K nnnn Defines the number of buffer pool entries that have a length of 4096 or less. This parameter is usually specified along with the BUFFERS-32K parameter. The minimum value is 124.
Buffers-32K nnnn Defines the number of buffer pool entries that have a length of 4097 or greater. This parameter is usually specified along with the BUFFERS-4K parameter. The minimum value is 15.
Files (z/VSE only) nnn | 001 Specifies the number of command log files to be processed (used for GENCARD).

Logging Options

Field Value Description
Target Name name The name you use to identify the target database.
Review Commands Y | N Indicates whether commands issued by Adabas Review should be included in the command processing for all reports.

REVIEW-COMMANDS=NO indicates that special Adabas commands for Adabas Review (for example V4 commands) are not used for accounting and monitoring. To suppress RC commands issued from the SYSREVDB application as well, set the Natural profile ADAPRM parameter ON (ADAPRM=ON).

REVIEW-COMMANDS=YES indicates that these commands are used for accounting and monitoring.
