Installation Jobs
Using System Maintenance Aid

Installation Jobs

The installation of Software AG products is performed by installation jobs. These jobs are either created manually or generated by System Maintenance Aid (SMA).

For each step of the installation procedure under z/OS and z/VSE, the job number of a job performing the respective task is indicated. This job number refers to an installation job generated by SMA. If you are not using SMA, an example installation job of the same number is provided in the job library on the NVS installation tape; you must adapt this example job to your requirements. Note that the job numbers on the tape are preceded by the product code (for example, NVSI070).

Using System Maintenance Aid

For information on using Software AG's System Maintenance Aid (SMA) for the installation process, refer to the System Maintenance Aid documentation.

Prerequisites

Products and versions are specified under Natural and Other Software AG Products and Operating/Teleprocessing Systems Required in the current Natural Release Notes.

If you are not using System Maintenance Aid, adapt and run job NVSTAPE to copy the dataset from tape to disk. NVSTAPE is contained in sublibrary NVSvrsJ on the Natural installation tape.

The dataset type and the space it requires on disk are shown in the Report of Tape Creation.

Installation Procedure - z/OS and z/VSE

To install NVS under the operating systems z/OS and z/VSE, perform the following steps:

Step 1: Define CICS RDO Definitions - Job I005

Define CICS RDO Definitions for sample VSAM files.

Step 2: Prepare NVS Demo File - Job I008, Steps 1403 to 1407

Load the VSAM demo file EMPL (dataset NVSvrs.EMPL). Define the alternate index path EMPLX for the file EMPL.

Step 3: Create NVS Parameter Module - Job I055, Steps 1400 and 1401

Edit, assemble, and link the NVS parameter module NVSPARM. See Assembling the NVSPARM Parameter Module in the section Parameters, for a description of the parameters which can be specified.

Step 4: Create NVS I/O Module - Job I055, Steps 1410 and 1411, or Job I070, Step 1400

Assemble and link the NVS I/O module.
- If you install NVS under CICS, use the I/O module NVSCICS; for this module, use Job NVSI070 (Step 1400).
- If you install NVS under Com-plete, the I/O module NVSMISC must be assembled by using the parameter SMARTS=YES (Steps 1415 and 1416). See also SMARTS in the section Parameters.
- If you install NVS in any other environment, use NVSMISC. See the description of the parameters which can be specified in NVSMISC.
Note:
Under CICS versions below 5.3, the precompile step receives Condition Code 12, since new COMMAND level options are used depending on the CICS version applied. The corresponding assembly step must be finished with Return Code 0. This is normal and can be ignored.

Step 5: Adapt all Natural Parameter Modules - Jobs I060, I080

Modify the appropriate I060 and I080 jobs according to the TP monitor or batch modules you are relinking; for example, NATI060 for batch, NCOI080 for Com-plete and NCII080 for CICS. This applies also to Relink all Natural Nuclei below.

Add the following parameter and macro call to your Natural parameter modules:

VSIZE=72 NTDB VSAM, vsam-dbid

The value for VSIZE depends on the values specified in NVSPARM (see also the SIZE Parameter in the section Parameters).

Step 6: Relink all Natural Nuclei - Jobs I060, I080

For information on the components and structure of the Natural interface to VSAM, see also Components of Natural for VSAM and Structure of the Natural Interface to VSAM in the section General Information.

Add the following INCLUDE instruction in all links of the shared nucleus:

Platform	Instruction
z/OS	`INCLUDE NVSLIB(NVSNUC)`
z/VSE	`INCLUDE NVSNUC`

Add the following INCLUDE instruction in all links of the front-end:

Platform	Instruction
z/OS	`INCLUDE SMALIB(NVSPARM)`
z/VSE	`INCLUDE NVSPARM`

Add the following INCLUDE instruction in the link of the front-end in a CICS environment:

Platform	Instruction
z/OS	`INCLUDE SMALIB(NVSCICS)`
z/VSE	`INCLUDE NVSCICS`

Add the following INCLUDE instruction in the link of the front-end in any other supported environment (except CICS):

Platform	Instruction
z/OS	`INCLUDE SMALIB(NVSMISC)`
z/VSE	`INCLUDE NVSMISCD`

Add the following INCLUDE instruction in the link of the front-end under z/OS in any other supported environment (except CICS) if RLS=CHECK is specified in NVSPARM:

Platform	Instruction
z/OS	`INCLUDE CSSLIB (IGWARLS)`

The routine IGWARLS is a callable service to support RLS processing. It resides in the system library SYS1.CSSLIB. Add the corresponding DD statement to the link step.

Platform	Instruction
z/OS	Add the corresponding DD statements to the link step for Natural and link-edit the executable module.
z/VSE	Add the corresponding sublibrary for NVS to the search chain for the linkage editor and link-edit the executable module.

Step 7: Load Examples - Job I061, Step 1400

Use the system command INPL to load the NVS example programs (dataset NVSvrs.EXPL) into the Natural system file.

Step 8: Customize your TP Monitor

TP Monitor Instruction

CICS Add the entries for the NVS test files EMPLVS and EMPLVX to your RDO definition as described in Define CICS RDO Definitions above; you can find the CICS tables on the JOBS dataset as NVSI005.

TP Monitor	Instruction
CICS	Add the entries for the NVS test files `EMPLVS` and `EMPLVX` to your RDO definition as described in Define CICS RDO Definitions above; you can find the CICS tables on the `JOBS` dataset as NVSI005.
Com-plete	Catalog all VSAM files to Com-plete using the `CA` function of the Com-plete utility `UFILE`. If you have specified `PATH=CHECK` in `NVSPARM`: Catalog your front program to Com-plete using the `CA` function of the Com-plete utility `ULIB` with a region size of 40 KB if you have not changed the first default value of the `WPSIZE` parameter in the Natural parameter module. Under z/VSE, you must also catalog the front program as privileged. Load the IBM routine `IGG0CLA0` either in the LPA or as resident program using the Com-plete utility `UCTRL` under z/OS.
TSO	Add the following `ALLOC` statements to your Natural CLIST: ALLOC F(EMPLVS) DA('SAGLIB.VSAM.EMPL') SHR ALLOC F(EMPLVX) DA('SAGLIB.VSAM.EMPLX.PATH')SHR

Com-plete

Catalog all VSAM files to Com-plete using the CA function of the Com-plete utility UFILE.

If you have specified PATH=CHECK in NVSPARM:

Catalog your front program to Com-plete using the CA function of the Com-plete utility ULIB with a region size of 40 KB if you have not changed the first default value of the WPSIZE parameter in the Natural parameter module. Under z/VSE, you must also catalog the front program as privileged.
Load the IBM routine IGG0CLA0 either in the LPA or as resident program using the Com-plete utility UCTRL under z/OS.

TSO

Add the following ALLOC statements to your Natural CLIST:

ALLOC F(EMPLVS) DA('SAGLIB.VSAM.EMPL') SHR
ALLOC F(EMPLVX) DA('SAGLIB.VSAM.EMPLX.PATH')SHR

Installation Verification - z/OS and z/VSE

To verify whether the installation has been successfully performed, log on to the library SYSEXNVS and run the following programs:

NVSINST1
NVSINST2
NVSINST3
NVSINST4
NVSINST5
NVSINST6

If all these programs can be executed successfully, the installation of Natural for VSAM is completed and verified.

Note for z/OS batch mode: For verification in batch mode under z/OS you can run the job NVSI200 which executes the above programs.
