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:
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.
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.
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.
