Supported operating systems for the engine

To obtain the latest information about the required versions for each supported operating system, run the related report: 

On IBM i systems, JDK V1.8 must be installed in the /QOpenSys/QIBM/ProdData/JavaVM/jdk11/64bit directory.

The following libraries are required on Linux:

Starting from version 9.5, Fix Pack 2 the following library is required on Linux s390x:
  • GLIBCXX_3.4 
The presence of the above libraries on the local system is not verified when scanning system prerequisites at installation and upgrade time, so you should install the required libraries if you plan to use the extended agent for MVS.

On AIX OS version, ensure you have installed APAR IJ30808. For more information, see IJ30808.

On AIX systems, you must install the following system library: XL C++ Runtime or later.

  • Application Servers
  • Databases
  • Java
  • Web Browsers


Bundled DB2
IBM Workload Scheduler is supplied with a version of the DB2 server for the supported operating systems. This version can be installed by you separately before the product installation.

Note:The bundled version of DB2 is provided solely for use with IBM Workload Scheduler (see the product license for details).

Non-Bundled DB2
If you are using a supported version of DB2 for which you have purchased a license (a non-bundled DB2), then IBM Workload Scheduler will support it provided that the product edition is the same as the Bundled DB2 product edition or is a product edition with higher entitlements.
Remaining supported databases
The software for supported databases other than DB2 is not supplied with IBM Workload Scheduler: use your own version of the database software.


To obtain the latest information about plug-ins, see Automation Hub.


You must have access to the psjoa.jar file located in the ps_home\class directory of the indicated version.


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

Hardware requirements

This section contains the following sub-sections:

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, 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.

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
