This document describes how to install a server for the Natural Web I/O Interface (product code NWO) under the operating system z/OS.
The installation of the Web I/O Interface server is performed by
installation jobs. The sample jobs are contained in the data set
vrs represents the relevant product
version) and are
NWO, or generated by System Maintenance Aid (SMA).
The following topics are covered:
When used in this documentation, the notation vrs or vr represents the relevant product version (see also Version in the Glossary).
For details, refer to the section Prerequisites.
The installation medium contains the data sets listed in the table below. The sequence of the data sets and the number of library blocks needed are shown in the Software AG Product Delivery Report, which accompanies the installation medium.

(Job I008, Step 9410)
(Job I009 / Step 9410, 9420, 9430)
Step 9410 creates a sample
NWOCONFG for the batch
Step 9420 creates a sample
Clist to ping and
terminate a Web I/O Interface server.
Step 9430 creates a sample batch job to ping and terminate a Web I/O Interface server.
The following parameters of the configuration file have to be defined. See Configuring the Natural Web I/O Interface Server. For the other parameters, the default values may be used:
||Specify the name of the Web I/O Interface server front-end module you will generate in one of the following steps.|
||Specify the TCP/IP port number under which the server can be connected.|
(Job I054, Step 9410)
The NWO object modules must be linked with the necessary runtime extensions of your batch installations into executable load modules.
NATCNRFE applies to two different
products, the Natural Web I/O Interface Server (NWO) and the Natural
Development Server (NDV). So if you have already installed NDV, the module
NATCNRFE might already be there. However, it does not matter if
NATCNRFE with NWO because the resulting module from
either installation is the same.

If you have Natural subproducts for IBM database access installed, for example, Natural for DB2, Natural for DL/I, Natural for VSAM, you need to adjust the link job to include

Step 9415 creates a startup procedure for the batch server.

The Web I/O Interface server account must be defined in the z/OS UNIX System Services (OE segment). If the server account is not defined, the server ends with U4093 and system message
CEE5101C in the trace file.
If Natural Security (NSC) is installed:
The Web I/O Interface initial user ID (default ID is
STARGATE) must be defined in Natural Security with a valid default
library. Refer also to Web I/O Interface server configuration parameter
Alternatively, you can define the Natural profile parameter
AUTO=OFF (automatic logon) for the Web I/O
Each client user ID must be defined in Natural Security.
If the Web I/O Interface initial user ID is not defined, the Web I/O Interface server initialization aborts with a NAT0856.
If a Web I/O Interface client is not defined, the server connection returns an NSC error.
If you connect to the server from a Web I/O Interface client, make sure that the user who is defined in Natural Security has a default library or a private library defined. Otherwise, error message NAT0815 will occur.
If you configure the Web I/O Interface server to use an external
security system (see Web I/O Interface server configuration parameter
Web I/O Interface clients must be defined to the external security system.
