- where

vrs in a dataset name represents the version, release and system maintenance level of the product.

pp in a dataset name represents the patch level of the product.

Naming Conventions

In the following text, the library name JOBLIB stands for

the example job library (NWOvrs.JOBS), if you are not using SMA, or
the SMA job library (see SMA parameter JOBLIB in SMA Parameter Group BASIC), if you are using SMA.

Software AG uses the following naming conventions for source elements in the library JOBLIB:

A<product-code><function> = Assembler sources

L<product-code>< function> = Instruction for TSOSLNK/BINDER

Important Elements of the Job Library

Element	Description
`NWO-SYSPARM`	SMARTS parameters for NWO.
`NWO-CONFG`	NWO configuration parameters.
`NWO-ADAPARM`	`ADALNK` parameter for NWO.
`ANCFPRMW`	Assembler source - Natural Com-plete interface.
`ANWOPARM`	Assembler source - Natural parameter module for NWO.
`LNATSHAR`	Link instructions to link the Natural nucleus.
`LNWOFRNT`	Link instructions to link the NWO front-end module.
`START-NWO`	Procedure to start the NWO server.
`STOP-NWO`	Procedure to stop the NWO server.
`SHOW-SYSOUT`	Show `SYSOUT` file.

Installation Procedure

To install the Natural Web I/O Interface server in a SMARTS environment on BS2000/OSD, perform the following steps:

Step 1: Assemble the Natural Com-plete interface

(Job I055, Step 9410)

Assemble the source ANCFPRMW which is contained in the library JOBLIB.

Step 2: Assemble the Natural parameter module

(Job I055, Step 9420)

Assemble the source ANWOPARM which is contained in the library JOBLIB.

Step 3: Relink the Natural nucleus module

(Job I060, Step 3802)

This step is optional.

The Natural nucleus module must be relinked with the modules NATWEB if this has not been included yet. This is accomplished by using the source LNATSHAR which is contained in the library JOBLIB.

If you are using SMA, please refer to the SMA Readme file of NWOvrs (skeleton ##NWOvrs-README).

Step 4: Link the NWO front-end module

(Job I060, Steps 9410)

Link the NWO front-end module by using the source LNWOFRNT which is contained in the library JOBLIB.

Step 5: NWO clients must be defined to Natural Security

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 INITIAL_USERID. Alternatively, you can define the Natural profile parameter AUTO=OFF (automatic logon) for the Web I/O Interface.
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.

SMARTS Portable File System on BS2000/OSD

The following topics are covered below:

PFS Description
Allocating and Configuring a SMARTS Portable File System

PFS Description

SMARTS PFS (Portable or POSIX File System) implements a file system, known from UNIX systems, in a mainframe environment. Basically, it consists of a container file, which comprises all (UNIX) files and a corresponding (logical) access method, which processes all requested I/O operations.

The container file has to be allocated and preformatted using the BS2000/OSD procedure CREATE-PFS described below.

The PFS maps all file names to a node of a directory tree within the physical container file. In the case of BS2000/OSD, this container file is a PAM file with a block size of 4 KB (STD,2).

Within Natural, the actual path is specified by a corresponding DEFINE WORK FILE statement in the program which executes work file or print file access.

Each node (subdirectory) is separated by a slash (/) from its parent. The highest level qualifies the file name.

Example 1:

DEFINE WORK FILE 1 '/MISC/USER1/TESTFILE/'

Specifies: ROOT' => MISC => 'USER1 => 'TESTFILE

://MISC/USER1/TESTFILE

Example 2:

DEFINE WORK FILE 1 'TESTFILE2.W01'

Specifies: ROOT' => TESTFILE2.W01

Allocating and Configuring a SMARTS Portable File System

The Natural server uses the SMARTS portable file system (PFS) as a data container for Natural work files, print files, temporary sort files and the editor work file. The SMARTS PFS is the only storage medium available for these files under SMARTS.

In order to be able to use the PFS for Natural files you have to configure Natural accordingly:

For work files or print files, specify the access method AM=SMARTS, using the Natural profile parameters WORK (Work-File Assignments) and/or PRINT (Print File Assignments).
For temporary sort files, specify the type of storage medium STORAGE=SMARTS, using the Natural profile parameter SORT (Control of Sort Program).
And to allocate the editor work file in the PFS, specify the work file mode FMODE=SM, using the Natural profile parameter EDBP (Software AG editor buffer pool definitions).

If you use one of these options, you have to configure your SMARTS to use a PFS.

Step 1: Allocate a PFS

The file PFS.TST should not exist before the allocation procedure is executed, otherwise DMS error DMS0683 will occur.

The initialization can be done by using the following procedure:

/CLP FROM-FILE=*LIBRARY-ELEMENT(LIBRARY=APSvrs.LIB,ELEMENT=CREATE-PFS, -
/   TYPE=SYSJ),PROCEDURE-PARAMETERS=(FILE-NAME=PFS.TEST,SIZE=4096K,        - 
/   APS-LIB=APSvrs.LIB)

Step 2: Configure SMARTS

In the SMARTS SYSPARM configuration file, add the following lines:

CDI_DRIVER=('CIO,PAAQBIO,PFSTSK=PFSTASK,TRACE=N')
CDI_DRIVER=('TESTPFS,PAANPFS,LRECL=4096,CONTAINER=CIO:PFS/TEST/')
MOUNT_FS=('TESTPFS://','/')
