1.5 Configure DB2 to use non-standard ports - Port 50000
Information
If enabled, the default DB2 instance will be assigned a default port of TCP:50000 for TCP/IP communication. TCP:50000 is a widely known DB2 port, so this port assignment should be changed. Though deprecated, if you still use the DAS, its default port uses TCP:523 and should be changed.
Solution
Assign a non-default port (a value other than 50000) to the default DB2 instance.
