GOAL:
What happens if I check the connection status
GOAL:
How many TCP packets does the connected function exchange?
GOAL:
Being connected to the database using Progress Client/Server networking with the TCP/IP protocol
GOAL:
IF CONNECTED("sports") THEN MESSAGE "Connected" VIEW-AS ALERT-BOX.
FACT(s) (Environment):
Progress 9.1D
FIX:
The 4GL client sends first a TCP packet to the database server.
The database server acknowledges.
Than the client sends 2 TCP packets to the database server.
The database server sends 2 TCP packets back.
The client acknowledges to have received the packages from the server.
In total there are 7 TCP Packets exchanged between the client and the server machine.
