Network disconnect

If i Connect my Airport express router with airport extreme through cat 6 cable the entire network crashes

The network will crash if you originally configured the Express to connect to the network using wireless....and then you connect an Ethernet cable to it.
In a case like this, the Express is expecting a wireless connection since it was configured that way originally. When you connect the Ethernet cable it creates a massive feedback loop over the entire network.
The solution....if my hunch on the issue is correct.....is that you must reset the Express back to factory default settings, then connect the Ethernet cable, and then configure the Express.
When you do it this way, the configuration will be correct for a wired connection.

[NSFileHandle][Sockets] How to manage a network disconnection?

Hi,
I have built a client/server app that communicates via TCP/IP.
The *Client is an iPhone Application* that receives and sends many messages of variable sizes through a NSFileHandle object linked with a socket as its filedescriptor
I catch *incoming bytes trough an Observer* whose matching message is named "DataAvailable:(NSNotification *)aNotification".
*When the server stops*, the observer receives one last "dataAvailable" notification, which I try to manage with the [NSFileHandle readdataoflength:1]... that throws an *exception indicating the +connection has been reset by peer+* , which I catch and manage through a SocketDidDisconnect: homemade message.
But I have a *problem when the disconnection occurs directly because of a network disconnection* (I did disconnect the network on purpose) : I receive *no "DataAvailable" notification* (although it receive one I just close the connection from the server Application).
Then I thought I could check every 1/10 seconds if my connection was still ok by trying to do a [MyNSFileHandle ReadDataOfLength:0] : that would throw an exception as soon as my connection goes down. But obviously, reading 0 bytes does not have any effect. And since I don't wanna loose the queued incoming data by various random reading, I don't know how to detect such a network problem.
If any of your has an idea about *how to manage a network disconnection with a NSFileHandle without involving the random reading of queued incoming data*, I will listen to you with the greatest interest.
Thank you for reading till the end.

Looks like it will be of some help, yes.
But I don't have time to test it today. I'll tell you as soon as I have tested it.
Thanks anywa for your help

Network Disconnect During Live Meeting

During our Connect Professional live meetings, using VOIP for
hosts only, we continue to experience frequent freezes which
require that everyone login again or we receive "network
disconnect" messages which require a reboot of our Connect
enterprise server. The first meeting today had 77 connections and
the second meeting had 40 connections. Most are connected using
LAN. The audio features are quirky, i.e., hosts cannot always hear
music embedded in a presentation but participants have no problem
hearing it. Without warning, the entire meeting freezes. With both
meetings today, we had a network disconnect at 60 minutes into the
meeting. Although we can always get the meeting back up and
running, it is disruptive and aggravating for our attendees. We are
running presentations within the meeting space. No video. Adobe
tech support has not been able to offer any clues as to what is
happening. They now have all of the server error codes to study. If
anyone has had a similar experience or ideas for us to investigate,
we would be appreciative. We are running the current version on our
enterprise server. We have two more meetings scheduled for April
23rd.

Our organization had a similar problem. The Connect domain
was frozen during onligne meetings.
I did a search in the log files and with this error in the
system log:
"Server detected a backward timestamp"
I found this web site:
http://store1.adobe.com/cfusion/webforums/forum/messageview.cfm?forumid=15&catid=578&threa did=1232060&highlight_key=y&keyword1=Server%20detected%20a%20backward%20timestamp%20
Just like them, we try to not recording the meeting and it
solved temporairly the problem.
So my question, did you recorded the meeting room with the
build-in recorder function ?

There is no error in the primary database regarding this.
And after this no archive logs are being pushed to the standby database.
In V$ARCHIVE_DEST_STATUS view the column synchronizaion_status says CHECK NETWORK for dest_name LOG_ARCHIVE_DEST_2
Please advice.
Thanks.

Standby database,Possible network disconnect with primary database

Hello
I have a database on linux with standby configured on different server with same os and database version.When i was about clone primary database through OEM,it stuck in the middle and popup for recovery. I restored and recover whole database. Then, the alert log on the standby database shows this error.
Possible network disconnect with primary database.
I checked standby databsase,listener is up & running. But archive files are getting into standby database.
What should i do now? Please anybody can put some light on this.
Thanks
Ariz

Is there anything in the primary alert log? Can you tnsping the standby instance from the primary server, and the primary instance from the standby server?

CNS-9107 : Network disconnected when synchronize with PDA cradled

We are running into CNS-9107:Network disconnected during synchronization when we cradle the PDA. The problem only happens when the synchronization posts a sufficient amount of data, we saw the problem happened when the post content-length at 62K in my office, and 136K from my home, both are using the same mobile server, which is internet accessible.
We got err=10035 [WINCE: 10035] in the debug.txt after we turned on debug by adding DEBUG=1 in the polite.txt on the PDA.
Did anybody run into the same problem?
Could anybody shed some light on what err=10035 [WINCE: 10035] means?
Our environment are:
Server: Oracle Lite 10.2.0.2.0
PDA: Dell Axim X51v, Windows Mobile 5.0, our application is using Olite C# library to do the synchronization
Activeync: 4.2
Thanks in advance.
dliu

I post our findings here, in case anybody else runs in the same problem.
Possible solution 1: We got some patch DLL(olaes.dll and omcapi.dll) for WM 5.0 from oracle support, it looks promising to solve our problem, hope they will make to the future Oracle Lite release or patch.
Possible solution 2: In fact, this solution can only be used as a workaround, rather than a solution. After we upgrade the ROM to A12 for my Dell Axim X51v, we noticed there is a new Icon called 'USB to PC' under the Connections settings. We uncheck the 'Enable advanced network functionality', which seems resolve our problem too.
Hope this helps.

"Network disconnected during sync."

We are getting a strange error
"ERROR",CNS-9107,"07/17/2006 12:03:40","Network disconnected during sync. "
while synchronizing our Oracle Lite PocketPC application with Mobile Server. This only seems to be happening when we are uploading inspections with photo data, have anyone else experienced this problem?

During the 'Sending' phase from the client, a packed binary file (created by the composing phase) is being uploaded to the server, where it is then unpacked and the data put into the in queues.
During 'recieving' the server is creating a packed binary download file from two main sources - the out queue data for the user, and real time queries for any complete refresh items.
Have you set trace logs to SYNC for an example user? This should tell you whether or not the read of the out queues or complete refresh queries are at fault (you should see a list of publication items, and then the trace for each one in turn as it is processed). If the log shows that it is stopping on one publication item (normally a complete refresh), particularly where you have a long download time, then the query may be timing out.
If the sync log shows that all PI's have been processed successfully, then the problem is probably related to the send of the packed binary file. Have a look at the sync history for the user, in terms of record and byte count downloaded - is this excessive? Publication items containing BLOB columns (like images) set to complete refresh could be very large
On the client you should find a file(s) <USERNAME>olres.bin and/or <USERNAME>_olres.bin If you find them, the download at least started. When you say that the user cannot re-sync, do you mean that they get the same error reported? if so try deleting these files and see what happens (a server side error will be within the download file so will not go away until you kill the failed download files), if you still get the error quickly after removing the files, something has broken the activesync connection. If re-cradling the Pocket PC device to re-establish the connection works, then the problem is definitely in the activesync set up.. If it does not, is there anything in your network software that is restricting file downloads or packets?

How to Fire ondisconnect event when network disconnect suddenly

Hello Friends
                      can any body tell me how to clear the client entry from Adobe flash Media server 3.5. when net disconnect.
i was expecting that on netdisconnect from the client side end(which is connected to FMS) its onDisconnect event fire similarly as it fire for browser close.But when internet disconnect ondisconnect event not fires at FMS side is there any way to overcome this or any other event fire at that stage?
if it is possible to get any event on network disconnection at client sidetahn i can solve the issue.
Thanks and Regards
   Vineet osho

You must be getting the "NetConnection.Connect.Closed" as info.code in the onStatus for the NetConnection.
See http://livedocs.adobe.com/fms/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDoc s_Parts&file=00000742.html
nc = new NetConnection();
nc.onStatus = function(info){
    if (info.code == "NetConnection.Connect.Closed")
        // Netconnection has closed.

Why is the network disconnecting since downloading leopard os on my mac

Why is the network disconnecting since downloading lion10.7.2 ?
Message was edited by: Jimfromtx

Just corrected leopard to lion. I connect wirelessly to my router. Shows as connected in taskbar but isn't until I go to network settings and reconnect. Then will stay connected while I am using. When I leave computer alone for 30 minutes or so and return have to do reconnect process all over.

I have performed a media recovery but still I am facing the above errors. I thought earlier that there might be some network issue but we can ping the service names from both the primary and standby.
Can you please suggest me the steps that I can go through and fix this issue.

Dear buddies,
My database has a primary database which has a few sub databases.
They are in different servers.
One of the sub database has this error in the alert log everyday during backup time.
But finally the backup is successful.
Is this a network problem?
Please guide me.
Thanks in advance.

Network disconnects when speed is changed to gigabit

For over a year this machine has been connecting to a network at gigabit speed with no problems. Over the past few weeks it started having problems staying connected. All mounted volumes would be disconnected then an error message would pop up saying they were unavailable. No other machine on the network would have any trouble staying connected.
In the process of working with it I switched the ethernet speed to 100 instead of 1000 in the network control panel. At this point I would see the link status change to active in the info tab of Network Utility. Change it back to 1000 in the control panel and the status would change back to inactive in the utility.
What can be causing this? No other machine is having trouble like this. Nothing has been changed hardware or cable wise anywhere. Server, switches, workstation have all been powered down and restarted. Once the speed was changed to 100 base all has been fine, except for the speed.
Any thoughts or insight would be appreciated.
