Before you install, review the requirements in the following topics.
The software is supported on most major platforms, including AIX, HP-UX, Linux, and Solaris. For current information about supported releases:
The Information Builders Technical Support home page opens.
The Supported Systems and Adapters page opens.
The Supported Systems and Adapters page for that release opens.
The support chart for that platform opens.
In general, the operating system should have the latest cumulative patch levels applied.
Confirm that your installation software is labeled for your operating system level.
The following are approximate disk space requirements in megabytes. Specific sizes may vary slightly depending on the release being used and the options selected during configuration. The usage numbers do not include space for actual applications, databases, sort space, output preparation, or logs.

During installation, the disk space required is approximately 20 megabytes more than double the After Installation size. These numbers do not include space for applications. The ibisamp sample application requires an additional six megabytes.
Memory and shared memory usage depends on:
Memory usage differs depending on your implementation of UNIX and your FOCUS load.
The following table shows the approximate memory requirements for installing and running FOCUS.

You need one TCP/IP port for the FOCUS SU instance that you configure. By default, the installation procedure uses 8102. If you are installing FOCUS for Distributed Systems on a box that is also running WebFOCUS, you will need to enter a unique port number for the FOCUS SU instance to avoid conflict with WebFOCUS. To change the default port number, enter N when prompted to Proceed with defaults.
When installing and using FOCUS, you need two types of operating system user IDs:
The operating system ID you use when installing FOCUS owns the FOCUS files. You can create a new operating system ID to run and own the FOCUS files, or use any ordinary (non-superuser) ID. However, you should not install FOCUS as root. The FOCUS administrator ID should have a Korn, Bourne, or Bash shell as the default logon shell.
Note that the name iadmin is used to refer to the FOCUS administrator ID and group throughout this manual, but you may use any name for this ID. If you have WebFOCUS installed and already use iadmin for that administrator ID, you can still use iadmin for the FOCUS administrator. However, to avoid confusion, you may prefer to use a new ID for the FOCUS administrator.
For security purposes, you should not allow users and applications to use the iadmin ID. It should be available only to users who require administrative privileges.
