Applies to:

Net Configuration Assistant - NetCA - Version to [Release 11.1 to 11.2]

z*OBSOLETE: Microsoft Windows Server 2003 R2 (32-bit)
z*OBSOLETE: Microsoft Windows Server 2003 R2 (64-bit AMD64 and Intel EM64T)


 NETCA tool fails with messages that the port provided in the response file or in the GUI interface is not free.
 Running netstat in front of netca does not report the port to be in use.

The NetCA log shows errors like :

[main] [ 2010-05-06 09:29:36.109 CEST ] [ConfigureListener.isPortFree:1068] Created ServerSocket successfully.
[main] [ 2010-05-06 09:29:36.125 CEST ] [ConfigureListener.isPortFree:1054] wildcard InetAddress i.e InetAddress.getByName(::) : /0:0:0:0:0:0:0:0

New installation of 11g. The NetCA tool had a problem recognizing the ports because of an extra network card. As soon as the network card was removed, the NetCA executed successfully. The NetCA in 10g succeed in ignoring this unused network card , while in 11g NetCA has troubles identifying the ports.
