Controlling Client Access to Databases

You can control client access to Adabas databases in two ways:

Updates to the Directory Server configuration affect all clients that use the Directory Server updates to the Entire Net-Work Client configuration only affect the individual client. Entire Net-Work Client configurations can be very useful, therefore, if you want to test a configuration before publishing it for additional clients in the Directory Server.

Using a local Entire Net-Work Client configuration, you can control client access to Adabas databases in two ways:

The difference between the two methods is that you can specify additional connection parameters to a database in an Adabas access definition, whereas filtering controls all connections to the database. The two methods do work in conjunction. For example, if your filtering allows access to a given database, you can further qualify that access by specifying additional database access parameters, as described in this document. But, if your filtering does not allow access to a given database, no additional database access settings you may have specified are processed.

For complete information on filtering in the Entire Net-Work Client configuration, read Understanding Filtering.

Globally, you can perform such filtering in the Directory Server configuration, using partitioning and target definitions. For more information about using the Directory Server, read Software AG Directory Server Documentation.

This document describes how to control client access to databases in the Entire Net-Work Client configuration. It covers the following topics:


Maintaining Adabas Access Definitions

You can specify access definitions for specific Adabas databases. This access definition will be used when the database is accessed by the client. However, if filtering for the client configuration does not allow access to the database, this access definition is ignored.

This section covers the following topics:

Adding Adabas Access Definitions

Using the System Management Hub (SMH), you can add Adabas database access definitions for a client configuration.

Start of instruction setTo add an Adabas access definition to a client configuration:

Make sure you have accessed the System Management Hub.

  1. Select and expand Entire Net-Work Client from the list in tree-view to access the Entire Net-Work Client administration area.

  2. Select and expand Clients from the Entire Net-Work Client sublist.

    A list of machine names appears. The machines listed are computers on which clients managed by this installation of the System Management Hub are defined.

  3. Select and expand the client machine on which the client configuration is defined.

    The list of clients defined on the client machine appears.

  4. Right-click on the client configuration to which you want to add an Adabas access definition and select Add Adabas Access from the resulting drop-down menu.

    The Add Adabas Access Definition panel appears in detail-view.

  5. Modify the parameters on the Add Adabas Access Definition panel, as described in the following table. When all parameters are set as you want, click OK.

    Parameter Description Required? Default
    Adabas ID Specify the ID of the Adabas database to which this definition applies. Yes ---
    Protocol Type Select the communication protocol that will be used to connect to the database: TCP/IP or SSL Yes ---

    Port Value The port number of the host computer for the database. Yes ---
    Reconnect Click in the checkbox if you want reconnection attempts to occur if the database connection is disconnected due to some failure in the system. If this check box is not checked, no reconnection attempt is made. No No reconnection attempt is made.
    Retry Count Specify the number of times reconnection should be attempted. The valid range is "0" through "2147483648". A value should only be specified for this parameter if the Reconnect parameter is turned on (checked). If no value is specified, reconnection attempts do not occur. No 0
    Retry Interval Specify the number of seconds to wait between reconnection attempts. The valid range is "0" through "2147483648". A value should only be specified for this parameter if the Reconnect parameter is turned on (checked). If no value is specified, reconnection attempts do not occur. No 0
    Additional Parameters Specify additional parameters as described in Parameters. Separate parameters in this field with ampersand (&) symbols. No ---

    The Adabas access definition is added to the client configuration.
