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.
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
Maintaining the production Repository database
You must perform regular maintenance tasks on the production Repository database to ensure optimal performance. The maintenance tasks cull obsolete and unwanted data and reorganize the database as necessary.

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
    - Creating the database
      The production Repository database runs on a development logical partition (LPAR), and it is not necessary to run it on a business workload LPAR. You can duplicate the content of test Repository database to populate production Repository database without collecting and importing Inquisitor and Usage Monitor data again.
    - Configuring security
      Resource Access Control Facility (RACF®) security provides authentication, authorization, and auditing control for working with z/OS® systems.
    - Automating data collection and reporting activities
      When you configure the Usage Monitor, the Automation Server, and the Analyzer to run as started tasks, these data collection and reporting activities are automated.
    - Maintaining the production Repository database
      You must perform regular maintenance tasks on the production Repository database to ensure optimal performance. The maintenance tasks cull obsolete and unwanted data and reorganize the database as necessary.

Maintaining the production Repository database

You must perform regular maintenance tasks on the production Repository database to ensure optimal performance. The maintenance tasks cull obsolete and unwanted data and reorganize the database as necessary.

About this task

A database administrator or system programmer performs these maintenance tasks.

Procedure

Run the following jobs on a regular basis to delete old usage data, save space, and improve processing time:
1. Run the HZASUDEL job to delete usage data that are older than a specified period.
2. Run the HZASLDEL job to delete obsolete discovery and usage data for a specified system (LPAR).
3. Run the HZASPDEL job to physically delete data for all systems.
4. Run the HZASTPRM job to reset the status flag back to normal for tables in the production Repository database, following a failure.
5. Run the HZASIVP job to verify database changes since the product was released.
Run the following jobs on a regular basis to maintain the integrity and performance of data in the production Repository database:
1. Run the HZASUT01 job to backup the Repository database in Db2® or backup the zFS file system in SQLite.
2. Run the HZASUT02 job to restore the Repository database in Db2® or restore the zFS file system in SQLite.
3. Run the HZASUT03 job to reorganize the Repository database in Db2®.
4. Run the HZASUT04 job to update RUNSTATS statistics for the Repository database in Db2®.
