I'm using DB2-400 V5R2

I want to impact some minor changes from a database located in one host to an other one located in a second host.

I can see the tables of the host2 from host1 using the connect command.

What is the command to cancel this connection ? Apparently not disconnect

Is it possible to fire a trigger in a table of the host 1 to change the data of host 2 ? If no, then I must use the complex DPR...
