Installing and customizing HCL Z Asset Optimizer
The product installation involves downloading the product and available updates, preparing the database, and configuring and populating a test database. After verifying that all components are correctly installed, you duplicate the test database to create a production database where you automate data collection and import tasks.
Checklist of installation and customization tasks
This checklist includes a set of procedures for installing the product, creating a test database, populating data, and validating the test installation. When you complete these procedures, you are ready to create a production environment for HCL Z Asset Optimizer.
Preparing Db2® database prerequisites
The Db2® environment for the test z/OS® installation has prerequisites that you must configure.

Installing and customizing HCL Z Asset Optimizer
The product installation involves downloading the product and available updates, preparing the database, and configuring and populating a test database. After verifying that all components are correctly installed, you duplicate the test database to create a production database where you automate data collection and import tasks.
- Installation prerequisites
  Before you install HCL Z Asset Optimizer, verify that the required hardware and software are available in the installation environment.
- System configuration requirements
- Security and authorization requirements
  A z/OS® user ID with appropriate RACF® access is required to submit the batch jobs used in the customizing and operation of Z Asset Optimizer . Additional security and authorization configurations can be necessary, depending on your environment.
- Checklist of installation and customization tasks
  This checklist includes a set of procedures for installing the product, creating a test database, populating data, and validating the test installation. When you complete these procedures, you are ready to create a production environment for HCL Z Asset Optimizer.
  - Installing target libraries
    Before you can install HCL Z Asset Optimizer in a production environment, you can create a test environment.
  - Preparing Db2® database prerequisites
    The Db2® environment for the test z/OS® installation has prerequisites that you must configure.
  - Preparing local environment settings
    After installation, you can create a custom version of any job in the JCLLIB library or any parameter in the PARMLIB library, by copying and editing the relevant job in the HZASCUST member in the hza.SHZASAMP data set.
  - Configuring a test Repository database
    Configuring the test Repository database includes setting up database objects, creating the Global Knowledge Base (GKB) database, and configuring access to the Repository and the GKB databases. Most sites maintain both a test Repository database and a production Repository database. After you configure and validate the test Repository database, repeat this task to create the production Repository database.
  - Configuring a production Repository database
    Most implementations include a test Repository database and a production Repository database. Configuring a production Repository database involves creating the database and importing data, configuring security, and automating data collection activities

Preparing Db2® database prerequisites

The Db2® environment for the test z/OS® installation has prerequisites that you must configure.

Before you begin

Db2® database administrator and Z Asset Optimizer administrator privileges are required to perform this task.

Db2® for z/OS® must be installed. See Installation prerequisites. Db2® must have access to a minimum of 1600 cylinders of 3390 DASD space.

All Db2® table spaces defined in Z Asset Optimizer are partition-by-growth universal table spaces (UTS). UTS is a combination of partitioned and segmented table space schemes. Non-UTS table space types are deprecated.

Procedure

Run the DSNTIJCL job from Db2® SDSNSAMP to bind the DSNACLI plan and enable the Call Library Interface (CLI/ODBC) Db2® plan.
If you encounter a SQL error, code -805, rebind this plan with the latest Db2® maintenance package and include the following package in the job:
```
BIND PACKAGE (DSNAOCLI) MEMBER(DSNCLIMS) - CURRENTDATA(YES) ENCODING(EBCDIC) SQLERROR(CONTINUE)
```
Run the DSNTIJTM job from Db2® SDSNSAMP to bind the DSNREXX plan and enable the REXX Db2® plan.
