  • How can I log the response header and body in apache?

    - by acme
    I need to determine whether the server (Apache 2) is returning the full contents of a page along with its correct header or not. I have a PHP-script that is executed successfully, but the browser is getting only half of the html content, it's simply cut off. The client infrastructure is pretty complicated, using Novell BorderManager Proxys and stuff. To ensure the server is doing its job fine I want to log both header and body of the reponse. How can I achieve this? I looked into the mod_log_config module of apache (which is already installed and ready to be used), but honestly I didn't quite manage to configure it to output header and body somewhere. edit: I managed to log the header with LogFormat "%h %l %u %t \"%r\" %s %b \"%{HEADER_NAME}o\"" common2 CustomLog /var/log/apache2/response.log common2 But unfortunately the mod_log_config formats don't support the whole content body. Can anyone help?

  • is there a way to tail a log from remote server without using any user credentials?

    - by suhprano
    I run a script tailing a log in a remote server, like so: ssh userx@someip tail -f /data/current.log|python2.7 monitorlog.py There are dependencies and service requirements that disallows me to run the script off the remote server. (DB, ACLs, and path to another service is uses) Is there a way I can tail and monitor a log without using the ssh userx@someip? I thought about generating RSA keys but I think you still need a user to ssh.

  • MySQL InnoDB Corruption after power outage, possible to recover?

    - by Tim Hackett
    Hey Guys, I recently started trying to get Redmine up and running after a power outage that seems to have corrupted our InnoDB database in MySQL. Redmine had an extensive set of documentation that I would like to get even if redmine isn't able to run. The service fails on startup. I have tried inserting innodb_force_recovery = 4 per the documentation from the url in the error log. (also tried 1 thru 6 as I have backed up all directories after the corruption) I have verified through "mysqld-nt --print-defaults" that it is starting with the recovery option in the params. The machine is running Windows Server 2003 SP2, Xeon E5335 with 2GB RAM, MySQL is not mirrored to another machine, nor is the machine a mirror. I do not have any backups because the previous person did not set them up. Here is the error log: InnoDB: The log sequence number in ibdata files does not match InnoDB: the log sequence number in the ib_logfiles! 100308 14:50:01 InnoDB: Database was not shut down normally!

  • Should we exclude code for the code coverage analysis?

    - by romaintaz
    I'm working on several applications, mainly legacy ones. Currently, their code coverage is quite low: generally between 10 and 50%. Since several weeks, we have recurrent discussions with the Bangalore teams (main part of the development is made offshore in India) regarding the exclusions of packages or classes for Cobertura (our code coverage tool, even if we are currently migrating to JaCoCo). Their point of view is the following: as they will not write any unit tests on some layers of the application (1), these layers should be simply excluded from the code coverage measure. In others words, they want to limit the code coverage measure to the code that is tested or should be tested. Also, when they work on unit test for a complex class, the benefits - purely in term of code coverage - will be unnoticed due in a large application. Reducing the scope of the code coverage will make this kind of effort more visible... The interest of this approach is that we will have a code coverage measure that indicates the current status of the part of the application we consider as testable. However, my point of view is that we are somehow faking the figures. This solution is an easy way to reach higher level of code coverage without any effort. Another point that bothers me is the following: if we show a coverage increase from one week to another, how can we tell if this good news is due to the good work of the developers, or simply due to new exclusions? In addition, we will not be able to know exactly what is considered in the code coverage measure. For example, if I have a 10,000 lines of code application with 40% of code coverage, I can deduct that 40% of my code base is tested (2). But what happen if we set exclusions? If the code coverage is now 60%, what can I deduct exactly? That 60% of my "important" code base is tested? How can I As far as I am concerned, I prefer to keep the "real" code coverage value, even if we can't be cheerful about it. In addition, thanks to Sonar, we can easily navigate in our code base and know, for any module / package / class, its own code coverage. But of course, the global code coverage will still be low. What is your opinion on that subject? How do you do on your projects? Thanks. (1) These layers are generally related to the UI / Java beans, etc. (2) I know that's not true. In fact, it only means that 40% of my code base

  • Unable to cast transparent proxy to type &lt;type&gt;

    - by Rick Strahl
    This is not the first time I've run into this wonderful error while creating new AppDomains in .NET and then trying to load types and access them across App Domains. In almost all cases the problem I've run into with this error the problem comes from the two AppDomains involved loading different copies of the same type. Unless the types match exactly and come exactly from the same assembly the typecast will fail. The most common scenario is that the types are loaded from different assemblies - as unlikely as that sounds. An Example of Failure To give some context, I'm working on some old code in Html Help Builder that creates a new AppDomain in order to parse assembly information for documentation purposes. I create a new AppDomain in order to load up an assembly process it and then immediately unload it along with the AppDomain. The AppDomain allows for unloading that otherwise wouldn't be possible as well as isolating my code from the assembly that's being loaded. The process to accomplish this is fairly established and I use it for lots of applications that use add-in like functionality - basically anywhere where code needs to be isolated and have the ability to be unloaded. My pattern for this is: Create a new AppDomain Load a Factory Class into the AppDomain Use the Factory Class to load additional types from the remote domain Here's the relevant code from my TypeParserFactory that creates a domain and then loads a specific type - TypeParser - that is accessed cross-AppDomain in the parent domain:public class TypeParserFactory : System.MarshalByRefObject,IDisposable { …/// <summary> /// TypeParser Factory method that loads the TypeParser /// object into a new AppDomain so it can be unloaded. /// Creates AppDomain and creates type. /// </summary> /// <returns></returns> public TypeParser CreateTypeParser() { if (!CreateAppDomain(null)) return null; /// Create the instance inside of the new AppDomain /// Note: remote domain uses local EXE's AppBasePath!!! TypeParser parser = null; try { Assembly assembly = Assembly.GetExecutingAssembly(); string assemblyPath = Assembly.GetExecutingAssembly().Location; parser = (TypeParser) this.LocalAppDomain.CreateInstanceFrom(assemblyPath, typeof(TypeParser).FullName).Unwrap(); } catch (Exception ex) { this.ErrorMessage = ex.GetBaseException().Message; return null; } return parser; } private bool CreateAppDomain(string lcAppDomain) { if (lcAppDomain == null) lcAppDomain = "wwReflection" + Guid.NewGuid().ToString().GetHashCode().ToString("x"); AppDomainSetup setup = new AppDomainSetup(); // *** Point at current directory setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory; //setup.PrivateBinPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "bin"); this.LocalAppDomain = AppDomain.CreateDomain(lcAppDomain,null,setup); // Need a custom resolver so we can load assembly from non current path AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve); return true; } …} Note that the classes must be either [Serializable] (by value) or inherit from MarshalByRefObject in order to be accessible remotely. Here I need to call methods on the remote object so all classes are MarshalByRefObject. The specific problem code is the loading up a new type which points at an assembly that visible both in the current domain and the remote domain and then instantiates a type from it. This is the code in question:Assembly assembly = Assembly.GetExecutingAssembly(); string assemblyPath = Assembly.GetExecutingAssembly().Location; parser = (TypeParser) this.LocalAppDomain.CreateInstanceFrom(assemblyPath, typeof(TypeParser).FullName).Unwrap(); The last line of code is what blows up with the Unable to cast transparent proxy to type <type> error. Without the cast the code actually returns a TransparentProxy instance, but the cast is what blows up. In other words I AM in fact getting a TypeParser instance back but it can't be cast to the TypeParser type that is loaded in the current AppDomain. Finding the Problem To see what's going on I tried using the .NET 4.0 dynamic type on the result and lo and behold it worked with dynamic - the value returned is actually a TypeParser instance: Assembly assembly = Assembly.GetExecutingAssembly(); string assemblyPath = Assembly.GetExecutingAssembly().Location; object objparser = this.LocalAppDomain.CreateInstanceFrom(assemblyPath, typeof(TypeParser).FullName).Unwrap(); // dynamic works dynamic dynParser = objparser; string info = dynParser.GetVersionInfo(); // method call works // casting fails parser = (TypeParser)objparser; So clearly a TypeParser type is coming back, but nevertheless it's not the right one. Hmmm… mysterious.Another couple of tries reveal the problem however:// works dynamic dynParser = objparser; string info = dynParser.GetVersionInfo(); // method call works // c:\wwapps\wwhelp\wwReflection20.dll (Current Execution Folder) string info3 = typeof(TypeParser).Assembly.CodeBase; // c:\program files\vfp9\wwReflection20.dll (my COM client EXE's folder) string info4 = dynParser.GetType().Assembly.CodeBase; // fails parser = (TypeParser)objparser; As you can see the second value is coming from a totally different assembly. Note that this is even though I EXPLICITLY SPECIFIED an assembly path to load the assembly from! Instead .NET decided to load the assembly from the original ApplicationBase folder. Ouch! How I actually tracked this down was a little more tedious: I added a method like this to both the factory and the instance types and then compared notes:public string GetVersionInfo() { return ".NET Version: " + Environment.Version.ToString() + "\r\n" + "wwReflection Assembly: " + typeof(TypeParserFactory).Assembly.CodeBase.Replace("file:///", "").Replace("/", "\\") + "\r\n" + "Assembly Cur Dir: " + Directory.GetCurrentDirectory() + "\r\n" + "ApplicationBase: " + AppDomain.CurrentDomain.SetupInformation.ApplicationBase + "\r\n" + "App Domain: " + AppDomain.CurrentDomain.FriendlyName + "\r\n"; } For the factory I got: .NET Version: 4.0.30319.239wwReflection Assembly: c:\wwapps\wwhelp\bin\wwreflection20.dllAssembly Cur Dir: c:\wwapps\wwhelpApplicationBase: C:\Programs\vfp9\App Domain: wwReflection534cfa1f For the instance type I got: .NET Version: 4.0.30319.239wwReflection Assembly: C:\\Programs\\vfp9\wwreflection20.dllAssembly Cur Dir: c:\\wwapps\\wwhelpApplicationBase: C:\\Programs\\vfp9\App Domain: wwDotNetBridge_56006605 which clearly shows the problem. You can see that both are loading from different appDomains but the each is loading the assembly from a different location. Probably a better solution yet (for ANY kind of assembly loading problem) is to use the .NET Fusion Log Viewer to trace assembly loads.The Fusion viewer will show a load trace for each assembly loaded and where it's looking to find it. Here's what the viewer looks like: The last trace above that I found for the second wwReflection20 load (the one that is wonky) looks like this:*** Assembly Binder Log Entry (1/13/2012 @ 3:06:49 AM) *** The operation was successful. Bind result: hr = 0x0. The operation completed successfully.

WRN: It is recommended to inspect your application on whether this is intentional or not. WRN: See whitepaper http://go.microsoft.com/fwlink/?LinkId=109270 for more information and common solutions to this issue. Notice that the fusion log clearly shows that the .NET loader makes no attempt to even load the assembly from the path I explicitly specified. Remember your Assembly Locations As mentioned earlier all failures I've seen like this ultimately resulted from different versions of the same type being available in the two AppDomains. At first sight that seems ridiculous - how could the types be different and why would you have multiple assemblies - but there are actually a number of scenarios where it's quite possible to have multiple copies of the same assembly floating around in multiple places. If you're hosting different environments (like hosting the Razor Engine, or ASP.NET Runtime for example) it's common to create a private BIN folder and it's important to make sure that there's no overlap of assemblies. In my case of Html Help Builder the problem started because I'm using COM interop to access the .NET assembly and the above code. COM Interop has very specific requirements on where assemblies can be found and because I was mucking around with the loader code today, I ended up moving assemblies around to a new location for explicit loading. The explicit load works in the main AppDomain, but failed in the remote domain as I showed. The solution here was simple enough: Delete the extraneous assembly which was left around by accident. Not a common problem, but one that when it bites is pretty nasty to figure out because it seems so unlikely that types wouldn't match. I know I've run into this a few times and writing this down hopefully will make me remember in the future rather than poking around again for an hour trying to debug the issue as I did today. Hopefully it'll save some of you some time as well in the future.© Rick Strahl, West Wind Technologies, 2005-2012Posted in .NET  COM   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • How do I overcome paralysis by analysis when coding?

    - by LuxuryMode
    When I start a new project, I often times immediately start thinking about the details of implementation. "Where am I gonna put the DataBaseHandler? How should I use it? Should classes that want to use it extend from some Abstract superclass..? Should I an interface? What level of abstraction am I going to use in my class that contains methods for sending requests and parsing data?" I end up stalling for a long time because I want to code for extensibility and reusability. But I feel it almost impossible to get past thinking about how to implement perfectly. And then, if I try to just say "screw it, just get it done!", I hit a brick wall pretty quickly because my code isn't organized, I mixed levels of abstractions, etc. What are some techniques/methods you have for launching into a new project while also setting up a logical/modular structure that will scale well?

    My Apache access log contains weird GET and POST requests, is it possible to examine which of these are harmful? For example: 114.232.151.185 - - [11/Jun/2014:20:11:33 +0200] "GET http://hotel.qunar.com/render/hoteldiv.jsp?&__jscallback=XQScript_4 HTTP/1.1" 404 1167 103.30.175.10 - - [12/Jun/2014:08:35:17 +0200] "GET /vtigercrm/ HTTP/1.1" 404 1034 69.174.245.163 - - [14/Jun/2014:01:22:38 +0200] "GET /w00tw00t.at.blackhats.romanian.anti-sec:) HTTP/1.1" 404 1034 69.174.245.163 - - [14/Jun/2014:01:22:38 +0200] "GET /phpMyAdmin/scripts/setup.php HTTP/1.1" 404 1034 94.74.229.110 - - [16/Jun/2014:18:46:43 +0200] "GET http://www.msftncsi.com/ncsi.txt HTTP/1.1" 404 1037 80.73.11.164 - - [20/Jun/2014:01:52:14 +0200] "POST /cgi-bin/php?%2D%64+%61%6C%6C%6F%77%5F%75%72%6C%5F%69%6E%63%6C%75%64%65%3D%6F%6E+%2D%64+%73%61%66%65%5F%6D%6F%64%65%3D%6F%66%66+%2D%64+%73%75%68%6F%73%69%6E%2E%73%69%6D%75%6C%61%74%69%6F%6E%3D%6F%6E+%2D%64+%64%69%73%61%62%6C%65%5F%66%75%6E%63%74%69%6F%6E%73%3D%22%22+%2D%64+%6F%70%65%6E%5F%62%61%73%65%64%69%72%3D%6E%6F%6E%65+%2D%64+%61%75%74%6F%5F%70%72%65%70%65%6E%64%5F%66%69%6C%65%3D%70%68%70%3A%2F%2F%69%6E%70%75%74+%2D%64+%63%67%69%2E%66%6F%72%63%65%5F%72%65%64%69%72%65%63%74%3D%30+%2D%64+%63%67%69%2E%72%65%64%69%72%65%63%74%5F%73%74%61%74%75%73%5F%65%6E%76%3D%30+%2D%6E HTTP/1.1" 404 1034 162.253.66.76 - - [24/Jun/2014:23:54:30 +0200] "GET /rutorrent HTTP/1.1" 400 226 122.226.223.69 - - [25/Jun/2014:01:14:27 +0200] "GET http://todd0738.gotoip4.com//hello.html HTTP/1.1" 404 1041 My Apache access log file: http://pastebin.com/2x0naQBK

  • PostgreSQL 9.1 on Ubuntu Lucid fails to start - how to debug?

    - by Tom Fakes
    I'm using Vagrant with Chef Solo to setup a Lucid 64 box. I'm using a Chef recipe to install PostgreSQL 9.1 from Martin Pitt's backports. The install goes ok until the point where the database is started with /etc/init.d/postgresql start There's a log pause and the command fails. If I run pg_ctl manually, the database starts! The entire contents of my postgresql-9.1-main log file is: 2012-05-07 11:01:18 PDT LOG: database system was shut down at 2012-05-07 11:01:16 PDT 2012-05-07 11:01:18 PDT LOG: database system is ready to accept connections 2012-05-07 11:01:18 PDT LOG: autovacuum launcher started 2012-05-07 11:01:18 PDT LOG: incomplete startup packet 2012-05-07 11:01:26 PDT LOG: received fast shutdown request 2012-05-07 11:01:26 PDT LOG: aborting any active transactions 2012-05-07 11:01:26 PDT LOG: autovacuum launcher shutting down 2012-05-07 11:01:26 PDT LOG: shutting down 2012-05-07 11:01:26 PDT LOG: database system is shut down I've tried to change the postgresql config file to get more info into the logfile, but that hasn't worked at all. How do I debug this to find out what is failing so I can fix it?

  • Are there any off the shelf solutions for feature use analysis?

    - by Riviera
    I write a set of productivity tools that sells online and have tens of thousands of users. While we do get very good feedback, this tens to come from only the most vocal users, so we fear we might be missing the big picture. We would like to know if there is any off the shelf (or nearly so) solution to capture usage of different features and to report usage patterns and trends over time. Note: These tools are native apps, not web-based. I know about Google Analytics and the like. They're great, but I'm looking for native code solutions.

  • Retrieving information from DOM elements returned using ajax

    - by niczoom
    I am new(ish) to jQuery and am testing out the extraction of DOM element data using jQuery. Below, detailed on the firebug console I tried to extract data 10 different ways (from 1- to 10-) using data returned directly from the ajax request (rtnData). And then to compare, I wrapped (rtnData) in a div to make it a jQuery object, and stored it in $test, (var $test= $('<div/>').html(rtnData);) Displayed below in Firebug Console Output, I cant figure out is why 5- return's nothing and e- returns the center tag contents. Same with 8- and e-, they both look for #ticker div id but 8- returns nothing and e- returns the correct html?? Also when searching for h1 tag .text(), why does 10- return blank and j- return the correct data? Thanks, Nic. Use the following page to run the ajax request below in Firebug Console: http://www.liamharding.com/pgi/pgi.php jQuery code ran using Firebug Console: $.ajax({ url: 'pgiproxy.php', type: 'POST', dataType: 'html', data: ({ data : $("#formdata").serialize(), mode : "graph"}), success: function(rtnData){ console.log("0- ", rtnData); console.log("1- ", $('img', rtnData)); console.log("2- ", $('a', rtnData)); console.log("3- ", $('span.cr', rtnData)); console.log("4- ", $('span.cr', rtnData).html()); console.log("5- ", $('center', rtnData)); console.log("6- ", $('table', rtnData)); console.log("7- ", $('#ticker_data', rtnData)); console.log("8- ", $('#ticker', rtnData)); console.log("9- ", $('#last', rtnData)); console.log("10- ", $('h1', rtnData).text()); var $test= $('<div/>').html(rtnData); console.log("z- ", $test); console.log("a- ", $('img', $test)); console.log("b- ", $('a', $test)); console.log("c- ", $('span.cr', $test)); console.log("d- ", $('span.cr', $test).html()); console.log("e- ", $('center', $test)); console.log("f- ", $('table', $test)); console.log("g- ", $('#ticker_data', $test)); console.log("h- ", $('#ticker', $test)); console.log("i- ", $('#last', $test)); console.log("j- ", $('h1', $test).text()); }, error: function(){ alert('ERROR'); } }); Firebug Console Output: 1- jQuery(img#GnuPlotChart 624e4629...8946.gif) 2- jQuery(a.button javascri...eload();, a.button javascri...close();) 3- jQuery(span.cr) 4- <span class="tl"></span><span class="tr"></span><span class="bl"></span><span class="br"></span> 5- jQuery() 6- jQuery(table.rbox-table) 7- jQuery(div#ticker_data.rbox) 8- jQuery() 9- jQuery(th#last, td#last.num) 10- z- jQuery(div) a- jQuery(img#GnuPlotChart 624e4629...8946.gif) b- jQuery(a.button javascri...eload();, a.button javascri...close();) c- jQuery(span.cr) d- <span class="tl"></span><span class="tr"></span><span class="bl"></span><span class="br"></span> e- jQuery(center) f- jQuery(table.rbox-table, table) g- jQuery(div#ticker_data.rbox) h- jQuery(div#ticker) i- jQuery(th#last, td#last.num) j- Legacy Charts

  • How do I configure SSIS logging to overwrite the log file?

    - by theog
    My SSIS package has logging configured with a SSIS log provider for text files, which works fine, but each time the package is run the log appends to the end of the log file. I want it to truncate the file and only keep the log from the most recent execution of the package, but I don't see an option anywhere to do that. I've tried both file usage types (Existing file and New file) in the File Connection manager with the same results.

  • Is there extensible structured file analyzer, like network analysis tools?

    - by ???
    There are many network analysis tools like Wireshark, Sniffer Pro, Omnipeak which can dump the packet data in structured manner. I'm just writing my own file analyzer for general purpose, which can dump JPEG, PNG, EXE, ELF, ASN.1 DER encoded files, etc. in tree style. There are so many file formats in the world that I can't handle them all. So I'm wondering if there's some software already there, with pluggable architecture and a large established file format repository?

  • nginx php-fpm empty site

    - by Katafalkas
    I am writing this as I was stuck trying to fix it whole night. We have recently migrated to a new server. Before migration we have been running our site on nginx + cgi (script). After migration we decided to try apache + mod_php. It was rather terrible, and I would like to migrate back to nginx, but this time I want it with php-fpm (as people say its a cool) So I did follow a number of guides and I think i done everything correctly. As well as that I have our old config files for "server" section, which i reviewed and places into new config. So I ended up having an empty site when I enter our URL. (By empty I mean blank page, no letter, errors or anything at all.) In the access log there are some weird errors like: 123.242.148.54 - - [22/Mar/2012:06:08:11 +0200] "-" 400 0 "-" "-" My guess is that php-fpm is not working, but not sure how to confirm it. Maybe some1 could give some help ? Would much appreciate. my nginx config: user nginx; worker_processes 12; error_log /var/log/nginx/error.log; #error_log /var/log/nginx/error.log notice; #error_log /var/log/nginx/error.log info; pid /var/run/nginx.pid; events { worker_connections 4096; } http { include /etc/nginx/mime.types; #default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; tcp_nodelay on; gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; fastcgi_buffer_size 256k; fastcgi_buffers 4 256k; server { listen 80; server_name www.example.com; access_log /var/log/nginx/example.access.log; error_log /var/log/nginx/error.log; root /home/www/example; index index.php; client_max_body_size 50M; #error_page 404 /404.html; # phpMyAdmin location /phpmyadmin { root /usr/share/; error_log /var/log/nginx/phpmyadmin.log; try_files $uri $uri/ /index.php; } location ~ ^/phpmyadmin/.*\.php$ { root /usr/share/; error_log /var/log/nginx/phpmyadmin.log; include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9000; } # Munin location /monitoring { root /var/www/; auth_basic "Restricted"; auth_basic_user_file /etc/nginx/conf.d/monitoring_users; error_log /var/log/nginx/monitoring.log; index index.html; } # The site location / { try_files $uri $uri/ /index.php/?$uri&$args; } # PHP interpreter location ~ \.php { include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9000; } }

  • Filtering bad requests from Apache -> logger -> rsyslog to syslog-ng on a remote logging server possible?

    - by zeyus

  • SQL SERVER – How to Roll Back SQL Server Database Changes

    - by Pinal Dave
    In a perfect scenario, no unexpected and unplanned changes occur. There are no unpleasant surprises, no inadvertent changes. However, even with all precautions and testing, there is sometimes a need to revert a structure or data change. One of the methods that can be used in this situation is to use an older database backup that has the records or database object structure you want to revert to. For this method, you have to have the adequate full database backup and a tool that will help you with comparison and synchronization is preferred. In this article, we will focus on another method: rolling back the changes. This can be done by using: An option in SQL Server Management Studio T-SQL, or ApexSQL Log The first two solutions have been described in this article The disadvantages of these methods are that you have to know when exactly the change you want to revert happened and that all transactions on the database executed in a specific time range are rolled back – the ones you want to undo and the ones you don’t. How to easily roll back SQL Server database changes using ApexSQL Log? The biggest challenge is to roll back just specific changes, not all changes that happened in a specific time range. While SQL Server Management Studio option and T-SQL read and roll forward all transactions in the transaction log files, I will show you a solution that finds and scripts only the specific changes that match your criteria. Therefore, you don’t need to worry about all other database changes that you don’t want to roll back. ApexSQL Log is a SQL Server disaster recovery tool that reads transaction logs and provides a wide range of filters that enable you to easily rollback only specific data changes. First, connect to the online database where you want to roll back the changes. Once you select the database, ApexSQL Log will show its recovery model. Note that changes can be rolled back even for a database in the Simple recovery model, when no database and transaction log backups are available. However, ApexSQL Log achieves best results when the database is in the Full recovery model and you have a chain of subsequent transaction log backups, back to the moment when the change occurred. In this example, we will use only the online transaction log. In the next step, use filters to read only the transactions that happened in a specific time range. To remove noise, it’s recommended to use as many filters as possible. Besides filtering by the time of the transaction, ApexSQL Log can filter by the operation type: Table name: As well as transaction state (committed, aborted, running, and unknown), name of the user who committed the change, specific field values, server process IDs, and transaction description. You can select only the tables affected by the changes you want to roll back. However, if you’re not certain which tables were affected, you can leave them all selected and once the results are shown in the main grid, analyze them to find the ones you to roll back. When you set the filters, you can select how to present the results. ApexSQL Log can automatically create undo or redo scripts, export the transactions into an XML, HTML, CSV, SQL, or SQL Bulk file, and create a batch file that you can use for unattended transaction log reading. In this example, I will open the results in the grid, as I want to analyze them before rolling back the transactions. The results contain information about the transaction, as well as who and when made it. For UPDATEs, ApexSQL Log shows both old and new values, so you can easily see what has happened. To create an UNDO script that rolls back the changes, select the transactions you want to roll back and click Create undo script in the menu. For the DELETE statement selected in the screenshot above, the undo script is: INSERT INTO [Sales].[PersonCreditCard] ([BusinessEntityID], [CreditCardID], [ModifiedDate]) VALUES (297, 8010, '20050901 00:00:00.000') When it comes to rolling back database changes, ApexSQL Log has a big advantage, as it rolls back only specific transactions, while leaving all other transactions that occurred at the same time range intact. That makes ApexSQL Log a good solution for rolling back inadvertent data and schema changes on your SQL Server databases.

  • How to log slow queries in shared hosting MySQL?

    - by tomaszs
    I have a shared hosting where I have my website and MySQL database. I've installed a open source script for statistics (phpMyVisites) and it started to work very slow lately. It's written using some kind of framework and has many PHP files. I know that to find slow queries I can use slow query log functionality in MySQL. But on this shared hosting I can not use this method because I can not change my.cnf. I don't want to change my statistics script to other and I don't want to mess around with all files of this script to find out where to put diagnostics code to log queries manually. I would like to do it without changes in PHP code. So my question is: How to log slow queries in these coditions?: Can't change my.cnf to enable slow query log Can't change statistics script to other Don't know how scrpt is written and where mysql commands are issued Can't ask my provider for slow query log Is there any method to do this in simple, easy, fast way?

  • How and when to log account access login with PHP?

    - by Nazgulled
    I want to implement a basic login system in some PHP app where no cookies will be involved. I mean, the user closes the browser and the login expires, it will remain active during the browser session (or if the user explicitly logs out) otherwise. I want to log all this activity and I'm thinking that every time the user refreshes the page, opens a different link or logs out, I record that time as the last access made by that user, overwriting the previous access log. But my problem is when and how should I insert another record into the database instead of overwriting the last one? Should I just define a timeout and if the last access was made above that timeout, another log should be inserted into the database? Should the session expire too after that timeout? Or is there a better way? Ideally, I would like to log the "log out action" when the browser was closed, but I don't think there's a way to detect that is there? Suggestions?

  • Deactivate any calls to Log before publishing: are there tools to do this?

    - by Nicolas Raoul
    According to Google, I must "Deactivate any calls to Log methods in the source code" before publishing my Android app (section 4 of the publication checklist). My open-source project is large and it is a pain to do it manually every time I release. Additionally, removing a Log line is potentially tricky, for instance: if(condition) Log.d(LOG_TAG, "Something"); data.load(); data.show(); If I comment the Log line, then the condition applies to the next line, and chances are load() is not called. Are such situations rare enough that I can decide it should exist? This is on the official checklist, so I guess many people do this on a regular basis. So, is there a tool that removes all Log lines? Preferably one that is not tricked by code like the above.

  • What's the difference between FireBug's conole.log() and console.debug() ?

    - by 6bytes
    A very simple code to illustrate the difference. var x = [0, 3, 1, 2]; console.debug('debug', x); console.log('log', x); // above display the same result x.splice(1, 2); // below display kind of a different result console.debug('debug', x); console.log('log', x); The javascript value is exactly the same but console.log() displays it a bit differently than before applying splice() method. Because of this I lost quite a few hours as I thought splice is acting funny making my array multidimensional or something. I just want to know why does this work like that. Does anyone know? :)

Here is my test xml file Test1 Test2 Test3 Test4 Test5 I keep getting the same error: W/System.err(22458): org.xmlpull.v1.XmlPullParserException: unexpected type (position:TEXT Code: public void xmlParser() throws XmlPullParserException, IOException, ParserConfigurationException, SAXException { Log.d("tag", "xmlParsing...."); Arithmetic arthm = new Arithmetic(); XmlPullParserFactory xmlPF = XmlPullParserFactory.newInstance(); xmlPF.setValidating(false); XmlPullParser xml = xmlPF.newPullParser(); InputStream raw = getApplication().getAssets().open("menu.xml"); xml.setInput(raw, null); xml.nextTag(); Log.d("tag", "start parsing...."); String elementText = null; String elemName = null; int nofTags = 0; while (xml.getEventType() != XmlPullParser.END_DOCUMENT) { Log.d("tag", "while(xml.next)..."); switch (xml.getEventType()) { case XmlPullParser.START_DOCUMENT: Log.d("tag", "while (xml.getEventType() != XmlPullParser.END_DOCUMENT)"); break; case XmlPullParser.START_TAG: Log.d("tag", " case XmlPullParser.START_TAG"); elementText = xml.getName(); Log.d("tag", "elementText = " + elementText); if (xml.getEventType() != XmlPullParser.END_TAG) { xml.nextTag(); } break; case XmlPullParser.TEXT: Log.d("tag", "case TEXT"); if (elementText.equals("menu") && xml.isWhitespace()) { Log.d("tag", "<" + elementText + ">"); arthm.menu_name = xml.getText(); Log.d("tag", "value " + xml.getText() + " added"); } else if (elementText.equals("item")) { arthm.description = xml.getText(); Log.d("tag", "value " + xml.getText() + " added"); } else if (elementText.equals("SUBCATEGORY NAME")) { arthm.subcategoryDesc.add(xml.getText()); Log.d("tag", "value " + xml.getText() + " added"); } else if (elementText.equals("SUBCATEGORY DESC")) { arthm.subcategoryName.add(xml.getText()); Log.d("tag", "value " + xml.getText() + " added"); } break; case XmlPullParser.END_TAG: Log.d("tag", "case END_TAG"); nofTags += 1; String tags = Integer.toString(nofTags); Log.d("tags", elementText + " number of tags" + tags); if (xml.nextTag() != XmlPullParser.START_TAG) { xml.next(); } break; case XmlPullParser.END_DOCUMENT: Log.d("tag", "case END_DOCUMENT"); break; default: break; } } Log.d("tag", "Success!"); } Thanks in advance.

  • mysql not starting

    - by Eiriks
    I have a server running on rackspace.com, it been running for about a year (collecting data for a project) and no problems. Now it seems mysql froze (could not connect either through ssh command line, remote app (sequel pro) or web (pages using the db just froze). I got a bit eager to fix this quick and rebooted the virtual server, running ubuntu 10.10. It is a small virtual LAMP server (10gig storage - I'm only using 1, 256mb ram -has not been a problem). Now after the reboot, I cannot get mysql to start again. service mysql status mysql stop/waiting I believe this just means mysql is not running. How do I get this running again? service mysql start start: Job failed to start No. Just typing 'mysql' gives: mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) There is a .sock file in this folder, 'ls -l' gives: srwxrwxrwx 1 mysql mysql 0 2012-12-01 17:20 mysqld.sock From googleing this for a while now, I see that many talk about the logfile and my.cnf. Logs Not sure witch ones I should look at. This log-file is empty: 'var/log/mysql/error.log', so is the 'var/log/mysql.err' and 'var/log/mysql.log'. my.cnf is located in '/etc/mysql' and looks like this. Can't see anything clearly wrong with it either. # # The MySQL database server configuration file. # # You can copy this to one of: # - "/etc/mysql/my.cnf" to set global options, # - "~/.my.cnf" to set user-specific options. # # One can use all long options that the program supports. # Run program with --help to get a list of available options and with # --print-defaults to see which it would actually understand and use. # # For explanations see # http://dev.mysql.com/doc/mysql/en/server-system-variables.html # This will be passed to all mysql clients # It has been reported that passwords should be enclosed with ticks/quotes # escpecially if they contain "#" chars... # Remember to edit /etc/mysql/debian.cnf when changing the socket location.
