problem after DB2 Express installatiion, there is no Listener Port on SVCENAME
netstat -an | grep DB2_portname
db2 get dbm cfg -> DB2_portname is defined on parameter: SVCENAME
DB2_portname is also defined in /etc/services
db2set -all
[g]DB2FCMCOMM=TCPIP6 -> thats a problem
as root:
db2set -g DB2FCMCOMM=TCPIP4
db2set -g DB2COMM=TCPIP
stop all db2 process and start db2!
