IBM InfoSphere Streams Version 4.1.0

Multiple installations of InfoSphere Streams on the same host

To run multiple installations of InfoSphere® Streams on the same host, each installation must be installed in a unique location.

Restriction: If you install different versions of InfoSphere Streams on the same host, separate versions of Streams Studio are required for each product version. If you install multiple installations of the same product version in different locations on a host, you can use the same version of Streams Studio for all installations.

You can access multiple installations of InfoSphere Streams at the same time by using the streamsprofile.sh script. This script determines which installation of InfoSphere Streams you are using.

When you run the source product-installation-root-directory/4.1.0.0/bin/streamsprofile.sh command, your shell session uses that installation of InfoSphere Streams. To use another installation, you can source a different streamsprofile.sh script from your shell session.

If you are using a shell initialization file such as home-directory/.bashrc to source the streamsprofile.sh script, you can change the default installation that you use by editing the initialization file before you run the source command.

The configuration files for an InfoSphere Streams installation are stored in the installation-owner-home-directory/.streams directory. Included in this directory are license files, global configuration data, and instance data. Be careful with the global configuration data because its location is shared by all the InfoSphere Streams installations.

Installing a later version of InfoSphere Streams in the same location as a previous installation upgrades only that particular installation. No other installations on the same host are affected.

Uninstalling InfoSphere Streams only affects that particular installation. This action does not affect other installations on the same host.
