Software requirements for WebSphere Application Server Liberty Base
WebSphere Application Server Liberty Base adopts a continuous delivery model where new versions are deployed on a monthly basis.
During formal testing, IBM Workload Scheduler and the Dynamic Workload Console were tested using WebSphere Application Server Liberty Base version 25.0.0.11. The minimum required version to successfully install the product is 25.0.0.9.
For the Dynamic Workload Console installed in a z/OS environment, testing was conducted using WebSphere Application Server Liberty Base version 25.0.0.9, which is also the minimum required version for that configuration.
For more information about which subsequent versions of WebSphere Application Server Liberty Base can be used in the future, see Recommended updates for WebSphere Application Server.

SAP
The support statement for SAP S/4HANA, on-premise edition, has been extended to 2020 and future fix packs, based on SAP_BASIS 7.55 component.
You must have one of the following SAP versions installed, configured, and working:
- 7.00
- 7.01
- 7.02
- 7.10
- 7.11
- 7.20
- 7.30
- 7.31
- 7.40
- 7.50, or 7.50 S/4HANA
To understand if a SAP System is compatible with IBM Workload Scheduler, check if your system exposes the following interfaces:
- BC-XBP 6.10 (V2.0) - Background Processing
- BC-XBP 7.00 (V3.0) - Background Processing
- BW-SCH 3.0 - Business Information Warehouse
- BW4-SCH - Business Information Warehouse for SAP BW/4HANA
If the above interfaces are exposed, IBM Workload Scheduler supports the SAP system.
IBM Workload Scheduler has obtained the Integration with RISE with SAP S/4HANA Cloud certification.
SAP Access Method Requirements
To have the SAP access method work correctly, ensure that you have installed the SAP NetWeaver RFC Library. At least SDK 7.50 is required. Download these libraries from the SAP Service Marketplace and copy them to the following directory:
On UNIX operating systems
TWA_DATA_DIR/methods
On Windows operating systems
TWA_home\methods
For details about installation, support, and availability of the SAP NetWeaver RFC Library 7.50, refer to the SAP note 2573790.

Hardware requirements
This section contains the following subsections:
For information about AIDA requirements, see AIDA Detailed System Requirements.
Permanent disk space requirements when installing the product
To obtain the latest information about permanent disk space requirements when installing IBM Workload Scheduler on supported operating systems, see Hardware requirements.
Notes:
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 IBM Workload Scheduler (without scheduling data), which is 2 GB.
Space requirements for operating IBM Workload Scheduler
The disk space requirements listed in the report does not include the space required to operate IBM Workload Scheduler. 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 IBM Workload Scheduler
The space required is very subjective and depends on how you use IBM Workload Scheduler. 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
IBM Workload Scheduler 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.
