Hardware requirements

This section contains the following subsections:

For information about AIDA requirements, see Detailed System Requirements for AIDA.

Permanent disk space requirements when installing the product

To obtain the latest information about permanent disk space requirements when installing HCL Workload Automation on supported operating systems, see Hardware Requirements.
Note:
Space for RDBMS
The disk space requirements listed in the report do not include the space required for the RDBMS software you have chosen, details of which can be obtained from their support documentation.

Nor do they include the additional space requirement for the base support of HCL Workload Automation (without scheduling data), which is 2 GB.

Space requirements for operating HCL Workload Automation
The disk space requirements listed in the report does not include the space required to operate HCL Workload Automation. For this you must consider the additional space required for the following:
  • Database data
  • Symphony file
  • Archive files (and their retention period)
  • Log files (and their retention period)
  • Temporary files that are placed on the local hard drive
  • Files associated with the jobs managed by HCL Workload Automation

The space required is very subjective and depends on how you use HCL Workload Automation. If you are already a user of the product, you will have an idea of how much space it currently occupies. However, you should bear in mind that each version of the system uses more disk space than the previous one. If you are a new user you will probably set up a test system to help you grow familiar with the product and you should be able to scale up the operating space requirements of the test system to give you an indication of how much space you will be using in a fully functional live system.

Disk space at installation
Before starting the installation or upgrade, ensure you have the necessary disk space available on the file system. Consider that the disk space check calculated by the installation considers the entire space occupied by the TWA_HOME directory. The space required by the backup is the sum of the following directories:
TWA_HOME/TWS + 
TWA_HOME/TDWB + TWA_HOME/wastools + 
TWA_HOME/properties

Temporary space requirements

To obtain the latest information about temporary space requirements, see Hardware Requirements.

Virtual memory swap space requirements

HCL Workload Automation requires a minimum of 2 GB of virtual memory swap space on the file system of any operating system.

Memory requirements

To obtain the latest information about memory requirements, see Hardware Requirements.
