Dynamic provisioning of directory instances with DPS - Part 2
By Sylvain Duloutre-Oracle on Sep 27, 2010
The goal here is still (see previous post ) to dynamically add/remove a directory server instance from the mesh with no or limited impact on the client applications and w/o altering the HW load-balancers that are commonly deployed in front of the directories. In the rest of this post, we assume that client applications access the directory services via an access layer provided by the Sun/Oracle Directory Proxy Server (DPS).
The second method consists in changing the configuration of each Directory Proxy Server. Each data source (directory server instance) is put in disabled mode so that DPS immediatly stops forwarding traffic to them. The property is-enabled can be changed to false. To reactivate a data source, set that property to true again.
e.g. dpconf set-ldap-data-source-prop homere.france.sun.com:20389 is-enabled:false
