For a complete list of system requirements (disk spaces, temporary spaces and RAM usage), see HCL Workload Automation Detailed System Requirements.
WebSphere Application Server Liberty Base
The latest versions of WebSphere Application Server Liberty Base can be downloaded from Recommended updates for WebSphere Application Server Liberty. For further details, see the Download Document at Product Requirements and Fix Pack readmes.
Before you install HCL Workload Automation for the first time, you must have one of the following databases installed. The following requirements apply to the RDBMS systems:
DB2
DB2® Enterprise Server Edition

A version of DB2® is bundled with the installation image. You can install DB2® Server and the master domain manager or Dynamic Workload Console on the same workstation, then configure the database drivers from any workstation in your environment.

You can install DB2® manually.

To install DB2® manually, run the DB2 server or client installation program on the product image. The setup files for DB2® are on the product images as follows:
Table 1. DB2® Setup files
Operating System Setup file
AIX®, HP-UX/IA64, SunOS/SPARC, SunOS/SPARC64, all Linux operating systems DB2/server/db2setup
SunOS/AMD64 DB2/wse/db2setup
Windows/x86 and Windows/AMD64 DB2\SERVER\setup.exe
Oracle
You can install Oracle in the following ways:
Oracle Enterprise Edition
The advantage of choosing Oracle Enterprise Edition is that you can implement the Oracle Partitioning feature to improve the performance of event-driven workload automation. This improves rule management performance, in particular the following queries: event_rule_instance, action_run, and operator_messages. For information about event-driven workload automation, see Overview.
Oracle Standard Edition
Oracle Standard Edition does not include the Oracle Partitioning feature. Installing this edition does not improve the performance of event-driven workload automation.

For supported versions, see the HCL Workload Automation System Requirements Document at HCL Workload Automation Detailed System Requirements.

Note:
  • When installing the product on a 64-bit library operating system, use an Oracle database on a 64-bit library.
  • When upgrading:
    • If you already have an RDBMS installed and you want to upgrade it, you must upgrade it after you upgrade HCL Workload Automation.
    • Use an Oracle database on a 64-bit library when installing the product on a 64-bit library.
For information about upgrading the RDBMS, see the data maintenance chapter in the Administration Guide.
Informix
Before you create the HCL Workload Automation schema on the database, you must have created the following db and sb spaces:
  • A db space sized 100 MB and with a page size of 8K or greater, referred to as DBSPNAME in the properties file customization steps.
  • A db space space sized 20 MB, referred to as TWS_DBSP_LOG in the properties file customization steps.
  • An sb space for blob and clob data, sized 100 MB, referred to as TWS_SBSP in the properties file customization steps.
OneDB
A decentralized backend, handling user authentication, data storage, and validation. Hosting an instance is very simple, so you can decide where you want to store your data, gaining complete control and ownership over your data.
MSSQL
Ensure you downloaded the JDBC driver for Microsoft SQL Server, including the following prerequisites libraries and class library files :
  • sqljdbc_auth.dll
  • sqljdbc4.jar
  • sqljdbc.jar
Also, before you create the HCL Workload Automation schema on the database, you must have created the directory where the HCL Workload Automation table spaces will be placed when the HCL Workload Automation schema is created. The default is C:\MSSQL.
Azure SQL
A family of managed, secure, and intelligent products topenhat use the SQL Server database engine in the Azure cloud
