Thread Anyone having client disconnections with latest builds?

Hi!

I have been experiencing disconnection problems in our client application in our local network. The client application disconnects from the server. Sometimes I can 'reconnect' but sometimes I have to close the app and reopen it again.

The client app executes the OnServerReconnect event when this happens, and I can try to reconnect or close the app.

I know this (probably) can be due to external causes, network problems, etc., but it seems like the remote timeout is reached more tan ever before and I would like to ensure there is no problema with latest builds or any configuration I should check.

RemoteTimeOut is set to 300
RemotePing is True
KeepConnections is True


Is there any test I can do that allows me to ensure that the problem is inside or outside the application? Anyone with similar network problems can suggest any network-checker app or something?

Thanks

Luis C.

Luis,

What about the Connection Timeout on the server, what is it set to?
Also, I once had an issue like this on a small network where the server was also a workstation and at some point they set it to turn the disk off after a few hours of inactivity.

Hi, Fernando.

Where can I see/set it?
I can't see any related property in the TDBISAMEngine component. Just ReadLock/WriteLock Timeout.

Luis,

You can set it with the Server Administration Utility.

There's a simple way to test this - just create a small application that connects via localhost/127.0.0.1 and see if *it* disconnects at any point.  If it does, then your client and server connection timeouts are set incorrect or there's a bug in DBISAM (I doubt that it's the latter, but..).

Hi!

I have been testing this and noticed that the server is "dissapearing" from the network constantly.
I have changed the wifi usb adapter and it seems it is working correctly for now.

Thanks

Luis,

I didn't know it is a wi-fi network.
I wouldn't trust in wi-fi for any critical connections, unless there is no other option.
There are so many things that might go wrong.
