 How to assign a DB2-Instance to a unique IP-Address (and Port - of course) I was told, this is not possible, but other products like Oracle or MQSeries do support this! What is true, what are the reasons? Is there a security risk, because the DB2-Instance provides service to any IP-Endpoint of a machine, just because of the addressed port? Thanks a lot!

I couldn't find anything in the DB2 manuals but using a software firewall might be an option. |

Indeed, I guess you'd set your firewall rules to only open the DB2 port (e.g. 50000) on a specific IP address. Phil |
