With Oracle Access Manager 11.1.1, the Embedded Credential Collector (IECC) is the default. The ECC was and is integrated with the OAM Server.
Access Manager 11.1.2 also supports the ECC by default. However, Access Manager 11.1.2 also enables you to configure an 11g Webgate to use as a detached credential collector (DCC).
An 11g Webgate configured to act as a detached credential collector (DCC) is known as anAuthenticating Webgate. Webgates that protect resources are known as Resource Webgates.
The DCC is considered more secure compared to the default embedded credential collector (ECC).
