If using a remote database for your WebSphere Commerce environment, specific TCP/IP servers need to be started.
DB2 Universal Database for iSeries is part of i5/OS and is started when the machine is started.
If you want to access the database from a remote node, start the database host server and the distributed data manager by issuing the following command from a command line:
STRHOSTSVR SERVER(*DATABASE) STRTCPSVR SERVER(*DDM)
