  • 1.  ports used by cdc agent

    Posted Wed December 07, 2022 11:30 AM
    we have cdc agents/instances on linux replicating data between db2 luw servers
    each instance is assigned a port : 10901 by default (10902 for second instance)
    when looking at port usage, we see many more ports being used : is this correct ? are they used for comms also ?

    > sudo su –

    > netstat -taonp | grep -i dmts | grep -i listen

    tcp6       0      0 :::1426                 :::*                    LISTEN      127654/dmts64-java   off (0.00/0/0)

    tcp6       0      0 :::46163                :::*                    LISTEN      127648/dmts64-java   off (0.00/0/0)

    tcp6       0      0 :::10901                :::*                    LISTEN      127654/dmts64-java   off (0.00/0/0)

    tcp6       0      0 :::10902                :::*                    LISTEN      127648/dmts64-java   off (0.00/0/0)

    tcp6       0      0 :::2843                 :::*                    LISTEN      127648/dmts64-java   off (0.00/0/0)

    tcp6       0      0 :::36800                :::*                    LISTEN      127654/dmts64-java   off (0.00/0/0)

    This is normal. A subscription requires four ports between the source and target. By default there will be various ports on the source allocated dynamically all communicating with the target listener port.

    The Access Server will also have multiple ports open to the source agent and to the target agent.
