  • Disable MySQL general logging without restarting?

    - by shantanuo
    Can I disable general logging completely without restarting the server? Because, per the documentation: SET sql_log_bin = {0|1} Disables or enables binary logging for the current connection (sql_log_bin is a session variable) if the client has the SUPER privilege. The statement is refused with an error if the client does not have that privilege. Can I enable/disable general log without restarting MySQL?

  • Create flow diagram programmatically

    - by Julian Lettner
    I want to visualize components and connections of a HVAC system with .NET/C#. The diagrams will just include a few different components and their connections. They do not have to comply to any formal standard and should look alike the diagrams attached. In addition the user should be able to select a single component/connection (so that I can display additional data). Which free drawing/charting library would you use and why? Thanks for your time.

  • Storing LDAP Credentials

    - by Floetic
    What's the ideal way to store login and password for LDAP membership providers in the web.config? Having the login and password stored in the provider under connectionUsername/connectionPassword attributes does not go well with me because, I would want to encrypt the connection string later on. Don't have much experience with this, and was wondering if anyone had any best practices for this.

  • Controling virtualbox internet access?

    - by HandyGandy
    I am finally going through the process of moving my XP into a vbox (host linux). The thing is that I am migrating a virtually clean install. So aside from the occasional antivirus scan, I want to make sure that my XP is not sending malware data (keystoke.logs, spam etc. ) out silently ( and thus having picked up some virus ). To that end I want to limit XP to contacting my LAN and a few internet sites. ( mainly sites that require proprietary windows only software to access, AV sites and Windows update ). I want XP to only access preapproved addresses. If it is trying to contact a nonapproved address, I want it somehow logged and access restricted until I allow access. I also don't want to have to decide whether to allow access to a site at my leisure. To keeps things clear let me give an example: I start my vbox/XP ( which I call MYXP) running on my linux box ( called MYLINUX connecting to the net through a linksys wrt54g ) and connects via samba to my LAN ( since my LAN seems to be possessed of every evil thing, it's address is 192.168.666. ). At the moment my configuration is set so that I allow MYXP to access 192.168.666 and www.MYANTIVIRUS_UPDATES.com and www.MS_UPDATES.com. Then on the VM I start a program which tries to make a connection to www.playmygame.com . www.playmygame.com is on my preapproved list so the connection goes through. Later I check attempted accesses and discover that it also tried to connect to www.mygame_high_scores.com I figure this is OK so I add www.mygame_high_scores.com to my approved list. Later, I again check address and discover that my VM/XP tried to access www.mygame_steals_your_identity.com. I do some checking and discover the address is registered to someone in Kiev, Nigeria. Since this doesn't sound kosher to me, I replace the MYXP VM with one that was backed up before I installed mygame. I remove www.playmygame.com and www.mygame_high_scores.com from my access list for MYXP. It should acomplish this with little overheard. When I am not running the VM ideally it should not have any overhead. Suggestions?

  • Error when creating ASP.NET website in Visual Studio

    - by Jim Bradley
    I'm trying to learn ASP.NET. I open Visual Studio (this happens in both 2008 and 2010) and creating a new ASP.NET website using .NET 3.5. When I attempt to run the website, a FireFox page opens up and tells me that it can't establish a connection to the server (localhost:####). There's no helpful error message, just "cannot connect." What could be causing this?

  • Raw XML Push from input stream captures only the first line of XML

    - by pqsk
    I'm trying to read XML that is being pushed to my java app. I originally had this in my glassfish server working. The working code in glassfish is as follows: public class XMLPush implements Serializable { public void processXML() { StringBuilder sb = new StringBuilder(); BufferedReader br = null; try { br = ((HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest()).getReader (); String s = null; while((s = br.readLine ()) != null) { sb.append ( s ); } //other code to process xml ........... ............................. }catch(Exception ex) { XMLCreator.exceptionOutput ( "processXML","Exception",ex); } .... ..... }//processXML }//class It works perfect, but my client is unable to have glassfish on their server. I tried grabbing the raw xml from php, but I couldn't get it to work. I decided to open up a socket and listen for the xml push manually. Here is my code for receiving the push: public class ListenerService extends Thread { private BufferedReader reader = null; private String line; public ListenerService ( Socket connection )thows Exception { this.reader = new BufferedReader ( new InputStreamReader ( connection.getInputStream () ) ); this.line = null; }//ListenerService @Override public void run () { try { while ( (this.line = this.reader.readLine ()) != null) { System.out.println ( this.line ); ........ }//while } System.out.println ( ex.toString () ); } } catch ( Exception ex ) { ... }//catch }//run I haven't done much socket programing, but from what I read for the past week is that passing the xml into a string is bad. What am I doing wrong and why is it that in glassfish server it works, and when I just open a socket myself it doesn't? this is all that I receive from the push: PUT /?XML_EXPORT_REASON=ResponseLoop&TIMESTAMP=1292559547 HTTP/1.1 Host: ************************ Accept: */* Content-Length: 470346 Expect: 100-continue <?xml version="1.0" encoding="UTF-8" ?> Where did the xml go? Is it because I am placing it in a string? I just need to grab the xml and save it into a file and then process it. Everything else works, but this.Any help would be greatly appreciated.

I can't seem to figure out how to enter the two different connection strings for this to run. ConnectionString="Dsn=Xdb;uid=xxx;pwd=xxxxxxx" ProviderName="System.Data.Odbc" ConnectionString="Dsn=Ydb;uid=xxx;pwd=xxxxxxx" ProviderName="System.Data.Odbc" Is this possible...am I just missing something?

  • how to use an mdf in App_Data with shared hosting

    - by name
    If I create a website that uses an mdf in App_Data with the connection string: Server=.\SQLExpress;AttachDbFilename=|DataDirectory|mydbfile.mdf;Database=dbname; Trusted_Connection=Yes; what do I need to do to run the site in a shared hosting environment? Do I need to copy the contents of my mdf to the main SQL Server engine of my host? Is there a way to use the non-SQLExpress engine of my host and still keep my mdf in my App_Data?

  • WCF timeout exception detailed investigation

    - by Jason Kealey
    We have an application that has a WCF service (*.svc) running on IIS7 and various clients querying the service. The server is running Win 2008 Server. The clients are running either Windows 2008 Server or Windows 2003 server. I am getting the following exception, which I have seen can in fact be related to a large number of potential WCF issues. System.TimeoutException: The request channel timed out while waiting for a reply after 00:00:59.9320000. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout. ---> System.TimeoutException: The HTTP request to 'http://www.domain.com/WebServices/myservice.svc/gzip' has exceeded the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout. I have increased the timeout to 30min and the error still occurred. This tells me that something else is at play, because the quantity of data could never take 30min to upload or download. The error comes and goes. At the moment, it is more frequent. It does not seem to matter if I have 3 clients running simultaneously or 100, it still occurs once in a while. Most of the time, there are no timeouts but I still get a few per hour. The error comes from any of the methods that are invoked. One of these methods does not have parameters and returns a bit of data. Another takes in lots of data as a parameter but executes asynchronously. The errors always originate from the client and never reference any code on the server in the stack trace. It always ends with: at System.Net.HttpWebRequest.GetResponse() at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout) On the server: I've tried (and currently have) the following binding settings: maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" It does not seem to have an impact. I've tried (and currently have) the following throttling settings: <serviceThrottling maxConcurrentCalls="1500" maxConcurrentInstances="1500" maxConcurrentSessions="1500"/> It does not seem to have an impact. I currently have the following settings for the WCF service. [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Single)] I ran with ConcurrencyMode.Multiple for a while, and the error still occurred. I've tried restarting IIS, restarting my underlying SQL Server, restarting the machine. All of these don't seem to have an impact. I've tried disabling the Windows firewall. It does not seem to have an impact. On the client, I have these settings: maxReceivedMessageSize="2147483647" <system.net> <connectionManagement> <add address="*" maxconnection="16"/> </connectionManagement> </system.net> My client closes its connections: var client = new MyClient(); try { return client.GetConfigurationOptions(); } finally { client.Close(); } I have changed the registry settings to allow more outgoing connections: MaxConnectionsPerServer=24, MaxConnectionsPer1_0Server=32. I have now just recently tried SvcTraceViewer.exe. I managed to catch one exception on the client end. I see that its duration is 1 minute. Looking at the server side trace, I can see that the server is not aware of this exception. The maximum duration I can see is 10 seconds. I have looked at active database connections using exec sp_who on the server. I only have a few (2-3). I have looked at TCP connections from one client using TCPview. It usually is around 2-3 and I have seen up to 5 or 6. Simply put, I am stumped. I have tried everything I could find, and must be missing something very simple that a WCF expert would be able to see. It is my gut feeling that something is blocking my clients at the low-level (TCP), before the server actually receives the message and/or that something is queuing the messages at the server level and never letting them process. If you have any performance counters I should look at, please let me know. (please indicate what values are bad, as some of these counters are hard to decypher). Also, how could I log the WCF message size? Finally, are there any tools our there that would allow me to test how many connections I can establish between my client and server (independently from my application) Thanks for your time! Extra information added June 20th: My WCF application does something similar to the following. while (true) { Step1GetConfigurationSettingsFromServerViaWCF(); // can change between calls Step2GetWorkUnitFromServerViaWCF(); DoWorkLocally(); // takes 5-15minutes. Step3SendBackResultsToServerViaWCF(); } Using WireShark, I did see that when the error occurs, I have a five TCP retransmissions followed by a TCP reset later on. My guess is the RST is coming from WCF killing the connection. The exception report I get is from Step3 timing out. I discovered this by looking at the tcp stream "tcp.stream eq 192". I then expanded my filter to "tcp.stream eq 192 and http and http.request.method eq POST" and saw 6 POSTs during this stream. This seemed odd, so I checked with another stream such as tcp.stream eq 100. I had three POSTs, which seems a bit more normal because I am doing three calls. However, I do close my connection after every WCF call, so I would have expected one call per stream (but I don't know much about TCP). Investigating a bit more, I dumped the http packet load to disk to look at what these six calls where. 1) Step3 2) Step1 3) Step2 4) Step3 - corrupted 5) Step1 6) Step2 My guess is two concurrent clients are using the same connection, that is why I saw duplicates. However, I still have a few more issues that I can't comprehend: a) Why is the packet corrupted? Random network fluke - maybe? The load is gzipped using this sample code: http://msdn.microsoft.com/en-us/library/ms751458.aspx - Could the code be buggy once in a while when used concurrently? I should test without the gzip library. b) Why would I see step 1 & step 2 running AFTER the corrupted operation timed out? It seems to me as if these operations should not have occurred. Maybe I am not looking at the right stream because my understanding of TCP is flawed. I have other streams that occur at the same time. I should investigate other streams - a quick glance at streams 190-194 show that the Step3 POST have proper payload data (not corrupted). Pushing me to look at the gzip library again.
