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.
