Before you can configure Oracle HTTP Server WebGate, you must have installed and configured a certified version of Oracle Access Manager.
At the time this document was published, the supported version was Oracle Access Manager 12c Release 2 (220.127.116.11). For the most up-to-date information, see the certification document for your release on the Oracle Fusion Middleware Supported System Configurations page.
For production environments, it is highly recommended that you install Oracle Access Manager in its own environment and not on the machines that are hosting the enterprise deployment.
For more information about Oracle Access Manager, see the latest Oracle Identity and Access Management documentation, which you can find in the Middleware documentation on the Oracle Help Center.
For Oracle Fusion Middleware 12c, the WebGate software is installed as part of the Oracle HTTP Server 12c software installation. See Registering and Managing OAM 12c Agents in Adminstrator’s Guide for Oracle Access Management.
