## ORB/IIOP Listener

This section describes known ORB/IIOP-Listener issues and associated solutions.

ID | Summary
--- | ---
4743366 | The address attribute in the iiop-listener element in the server.xml file does not support ANY. In the default configuration, the Sun Java System Application Server is configured with the address value of “0.0.0.0” in the `iiop-listener` element. This default configuration does not listen on IPv6 interfaces. It only listens on all IPv4 interfaces on a system. The value of ANY in the address element of the iiop-listener, that would allow the server to listen on all interfaces (IPv4 or IPv6) on a system, is not supported. The ANY value in the address attribute of the iiop-listener element in the `server.xml` file allows for listening on all interfaces available on a system.This support includes both the IPv4 and IPv6 interfaces. Solution For both IPv4 and IPv6 interfaces, use "::" in the address value of the `iiop-listener` element. This solution is only applicable to Solaris 8.0 and above.
4743419 | RMI-IIOP clients will not work for IPv6 addresses where DNS address lookups fail for the IPv6 address. If a DNS lookup for an IPv6 address fails, clients of Remote Method Invocation-Internet Inter-ORB Protocol (RMI-IIOP) will not work for IPv6 addresses. Solution Domain Name Service (DNS) should be set up at the deployment site in order to look up an IPv6 address.
4810199 | The optimized CORBA Util delegate, which is bundled with Sun Java System Application Server 7.0 Standard Edition, is not enabled by default. A default installation of Sun Java System Application Server 7 does not enable the use of the high performance CORBA Util delegate. As a result, you might experience a significant decrease in performance when using the JDK-bundled or Sun Java System Application Server-bundled ORB. Refer to the “High performance CORBA Util Delegate Class” section in the “ORB Tuning” module of the Sun Java System Application Server Performance Tuning Guide. Solution You can improve performance significantly by enabling the use of a high performance CORBA Util Delegate implementation. To enable the alternate CORBA Util Delegate, add the following to the Sun Java System Application Server configuration file, `server.xml`: `<jvm-options>-Djavax.rmi.CORBA.UtilClass=com.iplanet.ias.util.orbutil.IasUtilDelegate</jvm-options>`
4847269 | The J2SE 1.3.1_X client cannot communicate with Sun Java System Application Server 7. When the J2SE 1.3.1_X client communicates with Sun Java System Application Server 7, the client will core dump. Solution Use J2SE 1.3.1_04 for the client.
