Ports used by Oracle

We are currently using an application which is told to connect to an Oracle database on port 1521 via a Oracles JDBC thin driver.

I have noticed that when this application queries an Oracle 8.1.6 database on an x86 LINUX RH6.2 server a snoop shows that communication takes place at port 1521 on the Oracle server. As illustraded below:

client -> database TCP D=1521 S=51940 Ack=3872836040 Seq=1737507242 Len=745 Win=24820

database -> client TCP D=51940 S=1521 Ack=1737507987 Seq=3872836040 Len=43 Win=32780

client -> database TCP D=1521 S=51940 Ack=3872836083 Seq=1737507987 Len=22 Win=24820

database -> client TCP D=51940 S=1521 Ack=1737508009 Seq=3872836083 Len=655 Win=32780

However when the same host and application query an Oracle 8.1.6 database on a SPARC Solaris8 server a snoop shows that communication takes place on various high numbered ports. As illustrated below;

client -> database TCP D=54710 S=51938 Ack=2435930103 Seq=1701721649 Len=746 Win=24840

database -> client TCP D=51938 S=54710 Ack=1701722395 Seq=2435930103 Len=51 Win=24840

client -> database TCP D=54710 S=51938 Ack=2435930154 Seq=1701722395 Len=22 Win=24840

database -> client TCP D=51938 S=54710 Ack=1701722417 Seq=2435930154 Len=663 Win=24840

Can anyone tell me if there is some Oracle configuration parameter which would result in the server not using port 1521. I believe that the listeners on the oracle server are configured to use port 1521.
