The Entire System Server Interface is required if the product Entire System Server is to be used. The Entire System Server Interface is part of Natural and no extra installation is needed.

Additionally, Natural provides the libraries SYSNPE and SYSNPR.

SYSNPE is the Entire System Server online tutorial which is provided as a starting help for Entire System Server users. For more information about Entire System Server, see the Entire System Server documentation.

The library SYSNPR contains the program CHANGEDB which is used to change the database ID of the Entire System Server DDMs.

This document covers the following topics:

• Prerequisites

• Activation

• Changing the Database ID for the Entire System Server DDMs

---

Prerequisites

The Entire System Server Interface provides access to Entire System Server on z/OS, z/VSE and BS2000/OSD via Entire Net-Work. For full support of the Entire System Server Interface, Entire Net-Work Version 5.8.1 or above is required on the mainframe platforms.

Activation

The Entire System Server Interface is not active if you use the standard Natural configuration settings. The value of the Entire System Server Interface database (Natural profile parameter ESXDB) is set to 0 by default. To use the Entire System Server Interface you have to set the value of the parameter ESXDB to 148 using the Configuration Utility.

In the Configuration Utility, the parameter ESXDB is assigned in the parameter group Product Configuration of a parameter file.

Tip:
Locate this parameter by searching for "ESXDB". See Finding a Parameter in the Configuration Utility documentation for further information.

ESXDB specifies the database ID used for the DDMs of Entire System Server. This DBID does not specify the target DBID of Entire System Server requests but tells Natural which DBID is used for the cataloged Entire System Server DDMs. The effective Entire System Server target DBID will be specified with the NODE field which is part of all Entire System Server DDMs.

Important:
Change the value of ESXDB to 148 to run Natural with Entire System Server Interface support. All Entire System Server DDMs are cataloged with DBID 148.

After starting Natural again, you may access Entire System Server nodes running on the mainframes via Entire Net-Work.

The customization of Entire System Server Interface supports the modification of the Entire System Server DDMs only.

Changing the Database ID for the Entire System Server DDMs

The library SYSNPR contains the program CHANGEDB which is used to modify the database ID of all Entire System Server DDMs. You will find all Entire System Server DDMs in the library SYSNPE. The database ID entered as a new DBID value in the program CHANGEDB must also be specified as the value of the Entire System Server Interface database parameter (ESXDB) in the Configuration Utility.
