Software requirements for WebSphere Application Server Liberty Base

All operating systems supported by IBM Workload Scheduler are supported by IBM WebSphere Application Server Liberty Base.

IBM WebSphere Application Server Liberty ase 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 Version 9.5 were  tested using:

• WebSphere Application Server Liberty V18.0.04 Base
• WebSphere Application Server Liberty V19.0.0.1 Base

It is recommended that you download and install the latest declared tested version. 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.

Support for Internet Protocol version 6

IBM Workload Scheduler supports Internet Protocol version 6 (IPv6) in addition to IPv4. To help you in the transition from an IPv4 environment to a complete IPv6 environment, IBM Workload Scheduler provides IP dual-stack support. The product communicates using both IPv4 and IPv6 protocols simultaneously with other applications using IPv4 or IPv6.

This section contains the following sub-sections:

• Permanent disk space requirements
• Temporary space requirements
• Virtual memory swap space requirements
• Memory 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, 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

Table 2: Memory (MB) summarizes the memory requirements for the various components, on all operating systems:
