Firewall configuration guidelines for InfoSphere Streams

If your security plan requires a firewall on the host operating system or between hosts, the following communications must be enabled between hosts and blocked from unauthorized external access:

SSH communication between runtime hosts

Communication between InfoSphere Streams management services, which is limited to ports in the local port range (TCP/IP port numbers that are automatically assigned by the host machine)

TCP communication between processing elements (PEs), which is limited to ports in the local port range

HTTPS connections between the Streams Web Service (SWS) and InfoSphere Streams interfaces such as the Streams Console. Each InfoSphere Streams runtime instance that is running SWS requires a user-assigned HTTPS port.

All communication protocols between applications and any systems, such as databases or external analytics services

For more information, see the IBM InfoSphere Streams documentation that is available in the /home/streamsadmin/InfoSphereStreams/doc/install-and-admin directory.

Installation of Streams by root users

Opportunity Detection supports Streams integration with root users only. If you are running the installation utility as a root user, you are the owner of the InfoSphere Streams installation. During the installation, you can specify the location of the installed InfoSphere Streams files. The default location is home_directory/InfoSphereStreams.

The streamsadmin user owns the IBM InfoSphere Streams installation, and must exist before you run the InfoSphere Streams installation utility.
