Installer Tasks

The Installer for Linux and UNIX (Installer) performs a number of tasks before and after the actual install process of a PIF product on the target computer. The tasks performed before the PIF product is installed are called pre-install tasks, the tasks after the actual product installation tasks are called post-install tasks.

The Installer performs the following pre-install tasks:

Validate that the software is complete
Extract pre-install components to a temporary folder
Execute the migration script (only when a new product is installed)
Perform dialogs to retrieve necessary parameters
Create a backup from an installed product (in case of an update installation)

The Installer performs the following install tasks (actual product installation):

Read parameter values from the environment.
Install external pre-install components.
Execute pre-install scripts.
Install the components of the PIF product.
Install external post-install components.
Execute post-install scripts.
Register product information in the local database.

If an update installation of a PIF product fails, the Installer restores the backup of the installed PIF product as a post-install task, to reinstall the previous product version.
