This post covers common tasks for OTM application administrators — finding the installation path, restarting the application, applying Oracle patches, and resetting admin passwords.

OTM installation path:

To find the OTM home directory, log in to the OTM application and access the PropertiesServlet:

Click List to display the current G-Log properties. Note the following property — this is the base OTM installation path:

This is referred to as $OTM_HOME throughout this post. The actual path differs per installation depending on where your system administrator placed the OTM software.

OTM follows a standard three-tier architecture — a widely used design in enterprise software where the application is split into three distinct layers: Web Tier, Application Tier, and Database Tier. Each tier has a specific responsibility, and together they allow OTM to scale, be maintained, and support many users simultaneously.

Depending on the deployment model — on-premise or SaaS — the underlying infrastructure differs, but the three-tier concept remains the same. In on-premise deployments, your organization manages each tier on its own servers. In SaaS (cloud) deployments, Oracle manages the infrastructure and these tiers are hosted and maintained by Oracle.
