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:

Note:
SVC information does not appear in BS2000 environments; BS2000 does not use SVCs.

Reviewing Adabas Nucleus Targets and Session Statistics

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:

• Accessing the SVC List

• Displaying Targets Associated with an SVC or Router

• Displaying Adabas Nucleus Session Statistics

Accessing the SVC List

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 and z/VSE, 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 BS2000 environments, this screen is not displayed. The user only has access to the router (IDTNAME) on which this application is running. Instead of displaying this screen, control is passed to the Available Targets screen.

Displaying Targets Associated with an SVC or Router

To display a list of all targets known to a particular z/OS or z/VSE SVC number or to a BS2000 router:

• In z/OS and z/VSE environments, mark an SVC on the Active Adabas SVCs screen with an "X", and press ENTER.

  Or:
  In BS2000 environments, enter the AA command from any command line.

  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.

Listing and Selecting Adabas Review Hubs

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:

1. Enter the AH command on any command line.

   A pop-up screen listing the available hubs on the selected z/OS or z/VSE SVC or BS2000 router appears.

   Available Review Hubs on SVC 237 Please choose a Review Hub --------------------------------------------- _ 00041 _____ _____ _____ _ 00558 _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7-- Exit

   Note:
   In BS2000 environments, the text "on SVC nnn" does not display.

2. 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.

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. 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:

1. Enter the ET command on the command line and press ENTER.

   The Edit Target screen appears as shown below:

   02:54:32 A D A B A S - R E V I E W 2009-06-20 Edit Target HUB=15690 Database Parameters Numeric Delimiters +----------------------------+ +----------------------------------+ !

   Note:
   SVC information does not appear on this screen in BS2000 environments; BS2000 does not use SVCs.

   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 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
