Why are multiple IIOP listeners useful and how many listeners are allowed?
When configuring the ORB in the Admin Console, you can have multiple IIOP Listeners. The intention is to support an administrator’s desire to have an application server instance support one port for “plain” IIOP and another port for IIOP/SSL. The Administration interface lets you configure as many IIOP Listeners as you want, but only two can be enabled (Listener Enabled toggled on) at the same time. If you try to have more than two enabled at once, the Administration interface displays an error.
