Pre-Installation

The most time-consuming part of a TIBCO iProcess Engine installation is the collection of environment information and parameters. This section helps you complete this process.

Pre-Installation Tasks Checklist provides a checklist of the tasks that you must or may need to perform before installing the iProcess Engine. The table shows:

•

whether the root, iProcess Files-install Owner, iProcess Schema-install Owner, or DBA user needs to perform the task (see Organization Roles).

•

the status of a task, depending on whether you are installing a new iProcess Engine or upgrading an existing one. This is either:

—

Required —You must perform this task before installing the iProcess Engine.

—

Check — You may need to perform this task before installing the iProcess Engine, depending on your installation scenario.

—

Optional — You may want to perform this task before installing the iProcess Engine, but it is not essential.

—

N/A — You can install the iProcess Engine without performing this task.

For detailed information about each task, see Pre-Installation Tasks.

Tip	You may want to print this table as a useful quick reference when performing the pre-installation tasks. The `Done?` column in the table provides a place for you to tick off tasks that have been done.
