IBM InfoSphere Streams Version 4.1.1

Operating system requirements for InfoSphere Streams

InfoSphere® Streams supports Red Hat Enterprise Linux (RHEL), the Community Enterprise Operating System (CentOS), and SUSE Linux Enterprise Server (SLES).

Important:

If you are running InfoSphere Streams across multiple hosts, ensure that you satisfy the following requirements:
- All InfoSphere Streams hosts must run on the same product version and release of InfoSphere Streams.
- All InfoSphere Streams hosts must run on the same hardware system (x86_64 or IBM® Power Systems™) and system architecture (64-bit).
- All InfoSphere Streams hosts on IBM Power Systems must run in the same endian mode, either all big endian or all little endian.
- RHEL and CentOS hosts can run in a mixed operating system environment if all hosts have the same major operating system version (Version 6 or 7).
- A mixed operating system environment is not supported for SLES hosts.
If you are upgrading your RHEL or CentOS operating system version, see Considerations and restrictions when migrating RHEL and CentOS systems from Version 6 to Version 7.
InfoSphere Streams provides tools that help you to verify this requirement on single and multiple hosts:
- Before installation, run the dependency checker script to verify requirements on the resources that you plan to install InfoSphere Streams on. If you are installing the product on a cluster of resources, run the dependency checker script on each resource in the cluster. For more information about this tool, see InfoSphere Streams dependency checker script.
- After installation, use the streamtool checkhosts command to verify requirements on single or multiple resources. For more information about this command, see Verifying resource requirements.
