Version 8.2.1
 —  Installation on Mainframes  —

Before You Begin

This section contains information you should read before installing Natural Business Services or Natural Construct.

Note:
When installing both products, you must install Natural Construct before installing Natural Business Services.

This section covers the following topics:


Prerequisites

This section describes the software and hardware requirements for Natural Business Services and Natural Construct on mainframe platforms. The following topics are covered:

Natural Business Services

This section describes the software prerequisites for installing the Business Service Administration subsystem on the mainframe. This documentation assumes you are installing Natural Business Services for the first time.

To use the online job submission features, the NATRJE module must be installed and operational (see your Natural Installation and Operations documentation).

Before installing Natural Business Services, the following products must be installed on your server:

Natural Construct

Natural Construct V8.2 is compatible with the following Software AG products and versions:

Note:
If you are creating business services from existing Natural subprograms, Predict is not required. Predict, however, allows Natural Construct to use its relationships, views, verification rules, and field attributes (such as column headings, edit masks, and business data types) to generate consistent code.

The Natural Construct installation tape includes sample JCL for the installation (see the CSTnnn.JOBS dataset).

This guide assumes you are installing Natural Construct for the first time or upgrading from Natural Construct V5.3. If you are upgrading from any other version, read the release notes and installation guides for all versions between your current version and V5.3 and perform the required procedures.

As some components of Natural Construct require access to the Software AG editor, ensure that the editor is fully installed and operational. To use the online job submission features, you must also ensure that the NATRJE module is fully installed and operational. For information about the editor or NATRJE module, see your Natural installation and operations documentation.

Dataset Naming Conventions

The Business Service Administration subsystem and Natural Business Services installation tapes use a dataset-naming convention that identifies the product, version number, release number, system maintenance level, and dataset type. For example, the Natural Business Services installation tape includes the following dataset:

NBSnnn.INPL

This dataset name consists of the following components:

Component Description
NBS Product code (NBS for Natural Business Services or CST for Natural Construct)
n Version number
n Release number
n System maintenance level
INPL Dataset type

System Maintenance Aid (SMA)

To install Software AG products, use the installation jobs. You can either create these jobs manually using JCL or use System Maintenance Aid (SMA).

Notes:

  1. If you are not using SMA, the JCL for installing is included in Copy the Tape Contents to Disk. Adapt this sample job to your requirements.
  2. When not using SMA, you must reference the Natural Construct 227 LFILE in the JCL to invoke the INT* modules.

If you are using SMA, perform the following steps before generating jobs:

  1. Load the SMA table data as described in the System Maintenance Aid documentation (if you have not already done so).

  2. Set CST82n in the list of available products for your environment to TO BE INSTALLED.

  3. If you are performing a first-time installation, adapt the FCST and FCST-DBID parameters in the FILNUM parameter group to the required values.

To use SMA, set the following options in your SMA environment (specified on the Modify Environment panel). Verify all options before generating jobs, as they may be set from a previous installation.

CST-FIRST-INSTALL

To load a new Natural Construct system file, set this option to "Y". To migrate your existing system file to the current version, set this option to "N". The new help text, code frames, and models will be loaded.

CST-FULL-ENV

To establish an environment in which you can generate, catalog, and run generated modules, set this option to "Y". This will load the CSTnnn.INPL dataset.

Note:
The CSTnnn.INPL dataset contains the Predict modules and will automatically install theses modules in your environment.

CST-CAT-ENV

To establish an environment in which you can catalog and run (but not generate) generated modules, set this option to "Y". This will load the CSTnnn.INPC dataset (subset of CSTnnn.INPL).

CST-EXE-ENV

To establish an environment in which you can run (but not generate or catalog) generated modules, set this option to "Y". This will load the CSTnnn.INPE dataset (subset of CSTnnn.INPC).

CST-LOAD-PRD

To load the Predict definitions for the demo system and system file, set this option to "Y".

CST-LOAD-DB2

To install the demo system to access DB2 tables, set this option to "Y". (Natural for DB2 must be installed.)

CST-LOAD-VSAM

To install the demo system to access VSAM files, set this option to "Y". (Natural for VSAM must be installed.)

FCST

File number of the Natural Construct system file.

ESIZE-NAT (BS2000/OSD only)

ESIZE for batch environments (minimum is 220).

ESIZE-NRT (BS2000/OSD only)

ESIZE for TIAM environments (minimum is 220).

ESIZE-NUT (BS2000/OSD only)

ESIZE for UTM environments (minimum is 220).

FCST-DBID (z/OS only)

Database ID of the Natural Construct system file.

ESIZE-BATCH (z/OS only)

ESIZE for batch environments (minimum is 120).

ESIZE-ONLINE (z/OS only)

ESIZE for online environments (minimum is 220).

ESIZE (z/VSE only)

ESIZE for z/VSE environments (minimum is 220).

RUNSIZE

Size of the Natural runtime buffer (minimum is 40).

SYNERR

SYNERR option, which must be set to "ON".

Note:
The <DATSIZE> buffer is a variable-size buffer. If more storage is required during the session for local data areas, the <DATSIZE> buffer is expanded dynamically. In a thread environment, the <DATSIZE> may be temporarily allocated outside the storage thread if it becomes too large. The size of the <DATSIZE> buffer is reduced back to the minimum size when the application does not need the space any longer.

Description of Installation Tape

This section describes the installation tape for Natural Business Services. The Report of Tape Creation lists the volume serial number, media type, dataset names, and dataset sequence numbers. It also indicates the record layouts and disk storage required for each dataset.

Notes:

  1. If you are not using SMA, the JCL for installing is included in Copy the Tape Contents to Disk. Adapt this sample job to your requirements.
  2. When not using SMA, you must reference the Natural Construct 227 LFILE in the JCL to invoke the INT* modules.

This section covers the following topics:

Copy the Tape Contents to Disk

You may want to copy the datasets on the installation tape to disk. The disk storage required for each dataset is given in the Report of Tape Creation, which accompanies the installation tape. The procedure to copy the datasets to disk differs, depending on whether you are using System Maintenance Aid (SMA). If you are using SMA, refer to the System Maintenance Aid (SMA) documentation (included on the current Natural documentation CD).

If you are not using SMA, refer to one of the following sections:

BS2000/OSD Users

The following steps apply to BS2000/OSD users.

  1. Copy the SRVnnn.LIB library from tape to disk.

    This step is not required if you have already copied the SRVnnn.LIB library from another Software AG tape. For more information, see the #READ-ME file in this library.

    The SRVnnn.LIB library is stored on the tape as the SRVnnn.LIBS sequential file containing LMS commands. The current version nnn can be obtained from the Report of Tape Creation.

    To convert the SRVnnn.LIBS sequential file into an LMS-library, execute the following commands:

     /IMPORT-FILE  SUPPORT=*TAPE(FILE-NAME=SRVnnn.LIBS, -
      /   VOLUME=<volser>, DEV-TYPE=<tape-device>)
      /ADD-FILE-LINK  LINK-NAME=EDTSAM, FILE-NAME=SRVnnn.LIBS, -
      /   SUPPORT=*TAPE(FILE-SEQ=3), ACC-METH=*BY-CAT, -
      /   BUF-LEN=*BY-CAT, REC-FORM=*BY-CAT, REC-SIZE=*BY-CAT
      /START-EDT 
      @READ  '/'
      @SYSTEM 'REMOVE-FILE-LINK  EDTSAM'
      @SYSTEM 'EXPORT-FILE  FILE-NAME=SRVnnn.LIBS'
      @WRITE  'SRVnnn.LIBS'
      @HALT
      /ASS-SYSDTA  SRVnnn.LIBS
      /MOD-JOB-SW  ON=1
      /START-PROG  $LMS
      /MOD-JOB-SW  OFF=1
      /ASS-SYSDTA  *PRIMARY

    where:

  2. Copy the COPY.PROC procedure from tape to disk.

    To copy the COPY.PROC procedure to disk, call the P.COPYTAPE procedure in the SRVnnn.LIB library:

     /CALL-PROCEDURE  (SRVnnn.LIB,P.COPYTAPE), -
      /   (VSNT=<volser>, DEVT=<tape-device>)

    Note:
    If you use a TAPE-C4 device, you can omit the DEVT parameter.

  3. Copy all product files from tape to disk.

    To copy all Software AG product files from tape to disk, enter the COPY.PROC procedure:

      /ENTER-PROCEDURE  COPY.PROC, DEVT=<tape-device>

    Note:
    If you use a TAPE-C4 device, you can omit the DEVT parameter. The result from this procedure is written to the 'L.REPORT.SRV' file.

z/OS Users

The following steps apply to z/OS users. If the datasets for more than one product are on the tape, the COPY.JOB dataset contains the JCL to unload the datasets for all products. You must then perform the individual installation procedure for each component.

  1. Copy the COPY.JOB dataset from tape to disk.

    The COPY.JOB dataset (label 2) contains the JCL to unload all other datasets from the installation tape to disk. To unload COPY.JOB, use the following sample JCL:

    //SAGTAPE JOB SAG,CLASS=1,MSGCLASS=X
    //* ---------------------------------
    //COPY EXEC PGM=IEBGENER
    //SYSUT1 DD DSN=COPY.JOB,
    // DISP=(OLD,PASS),
    // UNIT=(CASS,,DEFER),
    // VOL=(,RETAIN,SER=<Tnnnnn>),
    // LABEL=(2,SL)
    //SYSUT2 DD DSN=<hilev>.COPY.JOB,
    // DISP=(NEW,CATLG,DELETE),
    // UNIT=3390,VOL=SER=<vvvvvv>,
    // SPACE=(TRK,(1,1),RLSE),
    // DCB=*.SYSUT1
    //SYSPRINT DD SYSOUT=*
    //SYSIN DD DUMMY
    // 

    where:

  2. Modify COPY.JOB to conform with your naming conventions.

    Before submitting this job, set the following parameters:

  3. Submit the job.

    To unload all other datasets from the tape to your disk, submit COPY.JOB.

z/VSE Users

The following steps apply to z/VSE users. If the datasets for more than one product are on the tape, the COPYTAPE.JOB member contains the JCL to unload the datasets for all delivered products (except datasets you can install directly from tape, such as INPL objects). You must then perform the individual installation procedure for each component.

  1. Copy the COPYTAPE.JOB dataset from tape to disk.

    The COPYTAPE.JOB dataset (file 5) contains the JCL to unload all other datasets from tape to disk. To unload COPYTAPE.JOB, use the following sample JCL:

    * $$ JOB JNM=LIBRCAT,CLASS=0,                                          + 
    * $$ DISP=D,LDEST=(*,UID),SYSID=1                                       
    * $$ LST CLASS=A,DISP=D                                                  
    // JOB LIBRCAT
