Supported Databases
* 
For the most current product platform support information, see http://support.ptc.com/partners/hardware/current/support.htm.
Integrity Lifecycle Manager uses a database to store data collected while using Integrity Lifecycle Manager, including version control information (revisions and project information). This same database also stores security, configuration, and administrative information for: Workflows and Documents, Configuration Management, and the Integrity Lifecycle Manager server.
* 
Each Integrity Lifecycle Manager server requires its own dedicated database instance. Multiple Integrity Lifecycle Manager servers sharing a single database instance is not a supported configuration.
