Author	Topic: Trouble reconnecting (8 messages, Page 1 of 1)
nsolot -DTN Guru- Posts: 273 Joined: Sep 4, 2004	Posted: Jan 11, 2005 07:49 PM Msg. 1 of 8 My feed hiccupped today. The connection manager stayed alive but other than time stamps data (quotes) stopped flowing. From another thread I see that sending "S,DISCONNECT\n" can be used to sumilate a disconnect, and it says sending "S,CONNECT\n" should reconnect. Disconnect is no problem and connection manager shows this status. When I send the connect instruction, connection manager reflects this by incrementing "Reconnections", but it fails. I bumped log level to 2.

I would really appreciate some guidance on how to elegantly deal with these disconnect/reconnect events within my program. BTW, I'm a paid up developer. >Date: Fri, 26 Mar 2004 14:20:50 -0600 >From: >Subject: Your IQ Developer Account is Now Active >Thank you for registering as an IQFeed Developer.

DTN_Glenn_B -Interested User- Posts: 14 Joined: Nov 24, 2004	Posted: Jan 14, 2005 09:27 AM Msg. 3 of 8 Sorry for the delay in a response. It's easy to miss new questions in a forum. What indications are you getting that the reconnect fails? After sending the CONNECT message are you receving back a "S,SERVER CONNECTED" message? After this, you need to set everything again (ie. watch list, news options, etc...). I don't see anything in your log indicating that the connect isn't working.

nsolot -DTN Guru- Posts: 273 Joined: Sep 4, 2004	Posted: Jan 14, 2005 10:14 AM Msg. 6 of 8 Taking a closer look at the log file, I notice when I send the S,SERVER CONNECT it logs: 2005-01-11 17:38:25: +Socket::Connect Connecting to preset IP address 66.112.156.222:60002 I'm guessing 60002 is a port number. Normal connection shows: 2005-01-11 17:39:42: +Socket::Connect Connecting to other IP address login.interquote.com:60020 2005-01-11 17:39:42: +Socket::Connect Connecting to preset IP address 66.112.156.211:60000 2005-01-11 17:39:43: +Socket::Connect Connecting to preset IP address 66.112.156.222:60002 Now I wonder if (and how to) I should change the port to 60000
DTN_Glenn_B -Interested User- Posts: 14 Joined: Nov 24, 2004	Posted: Jan 14, 2005 12:46 PM Msg. 7 of 8 You can send your log file to The IP addresses/ports in the log pertain to IQConnect and the external servers. You cannot connect to them directly. Like I said, according to the log snippit you posted, there isn't anything indicating a problem. For the next log please have it include the following sequence with the log level at 2. RegisterClientApp and connect socket. Set a watch for MSFT. Send the disconnect. Reconnect. Finally, set a watch for MSFT again. I will compare this to how it behaves for our apps. Glenn Benes Glenn Benes DTN Market Access, LLC. Edited by DTN_Steve_S on Sep 19, 2011 at 10:58 AM
nsolot -DTN Guru- Posts: 273 Joined: Sep 4, 2004	Posted: Jan 15, 2005 11:25 AM Msg. 8 of 8 Thanks Glenn for pointing me in the right direction. I solved the problem. Here's what I found to be the issue. When I send "S,SERVER DISCONNECT" , I get back 2 "S,SERVER DISCONNECTED" messages approx one second apart. My original code would send "S,SERVER CONNECT" each time I received the disconnected message. Setting log level to 4, I could see that IQ CM was attempting to reconnect, but the second time I sent the connect request it appears to mess things up. I modified my code to ignore the second "S,SERVER DISCONNECTED" message and it works fine.
