Opencms.properties
From OpenCms Wiki
The configuration file opencms.properties contains important configuration data that is required for starting OpenCms.
Database Access Information
Most importantly it contains information about the database connection and database user account that is used for connecting to the database
Setup/Update Wizard Activation
Another property controls the activation of the setup and update wizards. Running those wizards is a potentially dangerous operation and therefore it is only possible, if the following property has been set:
wizard.enabled = true
When the wizards are activated, it is not possible to normally use OpenCms. As soon as a system has been completely installed or updated from an earlier version of OpenCms, the wizard will automatically deativate itself by setting
wizard.enabled = false
