Maybe there are other methods, in this short article, a simple way to know the port that serves DB2 server.

We get the name of the service TCP / IP:

> db2 get dbm cfg | grep SVCENAME

Capture the result:

TCP/IP Service name (SVCENAME) = db2TRP

Look at /etc/services:

> cat /etc/services | grep sapdb2QRP

db2TRP 5912/tcp # DB2 Communication Port


The listening port is 5912!
