Preinstallation roadmap for the Teracloud® Streams interactive and silent installation methods

This roadmap summarizes preinstallation requirements and tasks for the Teracloud® Streams interactive and silent installation methods.

Table 1. Preinstallation roadmap for the interactive and silent installation methods
Task	Description
Review the installation considerations for Teracloud® Streams environments with multiple resources	The preferred and most reliable environment for multiple resources is a production environment. If you do not need high availability, a development or test environment might be your preferred option.
Create the user ID and group that will own the installation.	For both root and non-root installations, the user ID and group that own the installation must exist before running the Teracloud® Streams installation program. 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`. If you are running the installation program as a non-root user, you are the owner of the Teracloud® 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.
Create a response file, if required.	A response file is required for a silent installation.
Update installation script files, if required	In Version 7.2, there are changes to several Teracloud® Streams installation file names. For more information, see Upgrading to Teracloud Streams Version 7.2 from prior releases.
Optional: Configure a different temporary directory for installation processing.	By default, the temporary directory used by the Teracloud® Streams installation program is the /tmp directory. To configure a different directory, update the IATEMPDIR environment variable by entering the following command: export IATEMPDIR=`temporary-directory` where `temporary-directory` is the path to the temporary directory, for example, `/home/streamsadmin`. Note: If you do not have permission to execute files in the /tmp directory, the installation program might not run. To work around this issue, configure a different temporary directory.
