Detailed system requirements for IBM Workload Scheduler, version 10.2.2

Software requirements for WebSphere Application Server Liberty Base

WebSphere Application Server Liberty adopts a continuous delivery model where new versions are deployed on a monthly basis. During the formal testing phase, IBM Workload Scheduler and the Dynamic Workload Console were tested using WebSphere Application Server Liberty 24.0.0.3.

The minimum required WebSphere Application Server Liberty version to successfully install the package is 23.0.0.9.

Support for WebSphere Application Server Liberty Base version 25.0.0.3 will be available starting with the upcoming release of IBM Workload Scheduler version 10.2.4.

For more information about which subsequent versions can be used in the future, see Recommended updates for WebSphere Application Server.

Supported LDAP Servers

For a list of the LDAP servers supported by IBM Workload Scheduler, refer to WebSphere Application Server Liberty base documentation, for example: Configuring LDAP user registries in Liberty and Federation of user registries.

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 installed, configured, and working: SAP version 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.

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. You must download these libraries from the SAP Service Marketplace (visit https://support.sap.com/en/product/connectors.html) and copy them to the following directory:

• UNIX operating systems: <TWA_DATA_DIR>/methods
• Windows operating systems: <TWA_home>\methods

For further details, refer to the SAP note 2556567.

This section contains the following sub-sections:

• Disk space requirements
• Temporary space requirements
• Virtual memory swap space requirements
• Memory requirements

Disk space requirements when installing the product

To obtain the latest information about permanent and temporary disk space requirements when installing IBM Workload Scheduler on supported operating systems, run the Hardware requirements report and click on the relevant operating system link.

1. 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.

2. 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.

3. 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, run the Hardware Requirements report, and scroll to the relevant operating system.

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
