Goal

The goal of this KM is to provide information for a clustered install for Delegated Administrator.

Currently, there is no supported high-availability Delegated Administrator deployment documentation available.

Here are a few possible ways it could be achieved:

• Single web-container + Sun Cluster
• Single web-container + Zone Cluster
• Multiple web-containers + load-balancing (There are evidences of using this approach although there have been problems when running  different versions on each web-container)
• Multiple web-containers + app-server clustering + load-balancing
• An added complexity is having high-availability with split DA  front-end/back-ends.

There is not any reason for which we would not use a web container technology to provide high availability.  DA is just a LDAP client therefore, several instances can be installed.  This is the "multiple web-containers + load-balancing" option mentioned above.
