Access Manager Multiple Server Deployment

An Access Manager multiple server deployment has two or more host servers, with one or more instances of Access manager installed on each host server. Each Access Manager instance accesses the same Directory Server. You can configure the Directory Server instances in a multiple master replication (MMR) configuration, if required for your deployment.

The Access Manager instance installed on the first host server points to an instance of Directory Server. During installation using the Java ES installer, you can choose an existing Directory Server with or without an existing directory information tree (DIT), depending on your deployment.

You install subsequent instances of Access Manager on other host servers by running the Java ES installer, with the Access Manager instance pointing to a Directory Server with an existing DIT. Access Manager then does not write any information to Directory Server because it recognizes the Directory Server as already existing.

The following figure shows multiple Access Manager instances on different host servers with one Directory Server.
