Hello All, An issue with the network server default port number has recently come to my attention. The default port number for Network Server is 1527. I was told at one point that it was the well known port for DRDA, but that is in fact does not seem to be the case. The standard says the default is 446. The history of where 1527 came from is now lost but 1527 is registered to Oracle.
So the options as I see it are: A) Change Network Server to default to 446. This will affect existing apps. B) Register a new port for Derby and make that the default. Again we affect existing apps. C) Leave it at 1527 and print some sort of warning to the log/console, and document that users should change it. I don't know if this is acceptable or not. D) Something else?
