The correct order for performing an initial installation of SailPoint IdentityIQ is:

Ensure all of the application servers are stopped.

Stopping all application servers is crucial to prevent any conflicts or transactional interference during the installation process.

Un-jar the IdentityIQ WAR file in the desired directory of each application server.

Extract the IdentityIQ WAR file in the appropriate location for the application server. This step deploys the IdentityIQ application code.

Configure iiq.properties file with database credentials and datasource.

The iiq.properties file must be updated with correct database credentials and datasource configurations to establish a connection to the IdentityIQ database.

Create the IdentityIQ database.

A new IdentityIQ database must be created for the system. This is the foundation where all IdentityIQ data will be stored.

Generate database schema to include custom attributes by executing 'iiq schema'.

Use the iiq schema command to generate the necessary database schema. This includes tables, constraints, and other structural components for IdentityIQ.

Initialize default IdentityIQ system objects from 'iiq console' using the 'import' command.

Import default system objects like roles, policies, and configuration settings using the IdentityIQ console’s import feature. This sets up the base configuration.

Start all of the application servers.

Once everything is configured, start the application servers to make the IdentityIQ application available.

Apply the latest patch.

Finally, apply any patches to ensure the system is up to date with the latest security and feature enhancements.

Comprehensive Detailed Explanation with All IdentityIQ Engineer References

Stopping all application serversis necessary to avoid file locks and ensure the WAR deployment and database setup processes can proceed smoothly.

Un-jarring the WAR filedeploys IdentityIQ into the server directory structure, making its code accessible for execution.

Configuring the iiq.properties fileconnects IdentityIQ to the database, establishing where it will read and write data.

Creating the databaseis fundamental, as the IdentityIQ system relies on a structured data environment.

Generating the database schemavia iiq schema builds out the tables and structures necessary for storing identity, access, and policy data.

Initializing system objectssets up core elements of IdentityIQ (like roles, capabilities, and system configurations) required for its operation.

Starting the application serversactivates the IdentityIQ environment, allowing the system to begin processing requests.

Applying the latest patchensures that the installation is up-to-date with all bug fixes, enhancements, and security updates from SailPoint.
