Optimize your ORDA code with requests logging

Automatically translated from English

Ever need to analyze the traffic of your ORDA requests between a client and the 4D server? Sometimes it may take a while to receive a response from the server, which can make you wonder if it’s due to network traffic or to an unoptimized request you’ve written! Thankfully, 4D v17 R6 makes it possible to determine the likely reason(s) for this latency with the new ORDA methods available on the ds object. They’re not only debugging functions, they also allow you to optimize your ORDA code with a better understanding of the sent requests.

Concurrent merged clients from the same computer

Automatically translated from English

You asked for a way to run multiple clients on the same computer AND simultaneously connect them to the same 4D Server. We not only heard you, we’re giving you even more with 4D v17 R5! Each connection now includes a separated cache folder containing the connection’s IP address, port, and a hash code. Thanks to this, you can now also connect several clients from the same machine to multiple servers on different machines. There’s no configuration necessary, just launch and watch it work!
