IBM Streams 4.2.1

IBM Streams installation packages

Use the main installation package to install all of the product files on the resources in your IBM® Streams domain. To reduce the product size requirement on resources, the domain host installation package and resource installation package contain only a subset of the product files. For example, these installation packages do not include Streams Studio, Streams for Excel, and the toolkits.
If your IBM Streams environment includes multiple resources, you must install the main installation package on at least one resource by using one of the following installation methods:
  • Interactive graphical user interface (GUI) installation
  • Interactive console installation
  • Silent, response-file driven installation
After you install IBM Streams on at least one resource, you can install a subset of the product files on the other resources in your enterprise domain by using the domain host installation package or resource installation package.
  • If you plan to use the default IBM Streams resource manager, install the domain host installation package. You can install this package on resources by using the automated installation method or when you set up an enterprise domain.

  • If you plan to use an external resource manager, such as IBM Platform Symphony®, install the resource installation package. You can install this package on the externally managed resources when you set up an enterprise domain.

Alternatively, you can install the main installation package on each resource in the domain, or on a shared file system that is accessible by each resource in the domain.

Root or non-root users can install the main installation package and the domain host installation package. A root user must install the resource installation package.

If an IBM Streams installation is shared by multiple users, you must install the product in a directory that can be accessed by all users. For installations that are shared by multiple users, the preferred method is to install as the root user and specify a non-personal administrator ID, or install by using a non-personal administrator ID such as streamsadmin.

The main differences between a root and non-root user installation are file ownership and the default location of the installation files. If you are running the installation program as a non-root user, you are the owner of the IBM Streams installation. If you are running the installation program as a root user, the program prompts you to specify the user and group that will own the installed files. The root user cannot own the installed files.
Important: For both root and non-root installations, the user ID and group that own the installation must exist before running the IBM Streams installation program.
During the installation, you are prompted to specify the root installation directory for the installed IBM Streams files. The installation program appends a product version directory to the root directory. The default installation root directory depends on your authority:
  • If you have root authority, the default root directory is /opt/ibm/InfoSphere_Streams.
  • If you do not have root authority, the default root directory is home-directory/InfoSphere_Streams.
For example, if you are installing the product with root authority and accept the default installation directory, the product is installed in the /opt/ibm/InfoSphere_Streams/4.2.1.0 directory.
