  • Ubuntu 12.04 lightdm dumps to tty. Cannot start GUI interface when booting off harddrive, but can when booting off usb

    - by user72681
    When booting, lightdm dumps to tty. No GUI interface works- this is after a fresh install of Ubuntu 12.04 where the GUI interface works when running off the USB.

  • 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? :)

  • 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.

  • Why is user "lightdm" trying to log into my SBS 2003?

    - by user652740
    I have 7 Ubuntu desktops connected to a SBS 2003 using Centrify. I have a rather weird scenario, whereby a user with the name lightdm is trying to log into our server, possibly automatically. I thought lightdm was the session manager, not a user? Does anybody know what could be causing this? There is no user: "lightdm" on the server and the problem only comes from one of the 7 internal desktops connected to the server (its IP address is in the local network).

  • Log off from Remote Desktop Session does not closing Session, showing the login screen again on Wind

    - by Santhosha
    Hi As per requirement we have written one custom GINA. I have observed one interesting behavior in Windows XP 32 Bit(SP2). Customized GINA internally calls windows default Windows GINA(msgina.dll) and shows one extra window as per our requirement. I used to do remote desktop to XP machine from my machine. After replacing Windows GINA with customized GINA I tried to log off from the XP Machine(I am Using Remote Desktop Connection to log in), Log off completes successfully(After showing saving your settings, Closing network connections etc) and I will get log in screen which we get during log on, this is not expected comapred to other flavors of Windows OD. Where as in other operating systems such as Windows XP 64 Bit/ Windows 2003 32/64 Bit even after replacing the Windows Gina with custom GINA remote desktop session closes after log off from the machine. I have tried installing Novell GINA on Windows XP 32 Bit but i have not find any issue with that. I have Tried upgrading XP SP2 to SP3, still i am facing the same issue. Whether anyone faced Such issues when worked with Windows GINA? Thanks in advance Santhosha K S

  • How to use the Zend_Log instance that was created using the Zend_Application_Resource_Log in a model

    - by Alex
    Our Zend_Log is initialized by only adding the following lines to application.ini resources.log.stream.writerName = "Stream" resources.log.stream.writerParams.mode = "a" So Zend_Application_Resource_Log will create the instance for us. We are already able to access this instance in controllers via the following: public function getLog() { $bootstrap = $this->getInvokeArg('bootstrap'); //if (is_null($bootstrap)) return false; if (!$bootstrap->hasPluginResource('Log')) { return false; } $log = $bootstrap->getResource('Log'); return $log; } So far, so good. Now we want to use the same log instance in model classes, where we can not access the bootstrap. Our first idea was to register the very same Log instance in Zend_Registry to be able to use Zend_Registry::get('Zend_Log') everywhere we want: in our Bootstrap class: protected function _initLog() { if (!$this->hasPluginResource('Log')) { throw new Zend_Exception('Log not enabled'); } $log = $this->getResource('Log'); assert( $log != null); Zend_Registry::set('Zend_Log', $log); } Unfortunately this assertion fails == $log IS NULL --- but why?? It is clear that we could just initialize the Zend_Log manually during bootstrapping without using the automatism of Zend_Application_Resource_Log, so this kind of answers will not be accepted.

  • When I log on to my company desktop, I log on to a domain. How is this domain name installed?

    - by learnerforever
    Hi, When I have to work on my machine in company, I have noticed that I log on to a domain (named on the basis of company name) and not really on that computer. From, what I understand, this has a few advantages, the primary being that I just need one password for the domain and can work through any of the machines in company. My questions are : What software on desktop/network have to be installed so that the desktop recognizes and gives me option of logging into a domain. I would guess that a software can be installed on desktop, and there we can configure the IP address of domain server of company and port number, which handles authentication. Is this correct? This takes me to another question that how are softwares installed on end machines in a company. Going to each machine physically and installing looks very unweildy from administrator point of view. An obvious solution would be to install softwares (and updates) over network. My question on this are: What protocols,keywords come into picture when administrator installs OS,softwares,updates from his administrator machine to end machine through network. Thanks,

  • error in auth.log but can login; LDAP/PAM

    I have a server running OpenLDAP. When I start a ssh-session I can log in without problems, but an error appears in the logs.

  • Configured Samba to join our domain, but logon fails from Windows machine

    - by jasonh
    I've configured a Fedora 11 installation to join our domain. It seems to join successfully (though it reports a DNS update failure) but when I try to access \\fedoraserver.test.mycompany.com I'm prompted for a password. So I enter adminuser and the password and that fails, so I try test.mycompany.com\adminuser and that too fails. What am I missing? EDIT (Update 9/1/09): I can now connect to the machine and see the shares on it (see my response to djhowell's answer) but when I try to connect, I get an error saying The network path was not found. I checked the log entry on the Fedora computer for the computer I'm connecting from (/var/log/samba/log.ComputerX) and it reads: [2009/09/01 12:02:46, 1] libads/cldap.c:recv_cldap_netlogon(157) no reply received to cldap netlogon [2009/09/01 12:02:46, 1] libads/ldap.c:ads_find_dc(417) ads_find_dc: failed to find a valid DC on our site (Default-First-Site-Name), trying to find another DC Config files as of 9/1/09: smb.conf: [global] Workgroup = TEST realm = TEST.MYCOMPANY.COM password server = DC.TEST.MYCOMPANY.COM security = DOMAIN server string = Test Samba Server log file = /var/log/samba/log.%m max log size = 50 idmap uid = 15000-20000 idmap gid = 15000-20000 windbind use default domain = yes cups options = raw client use spnego = no server signing = auto client signing = auto [share] comment = Test Share path = /mnt/storage1 valid users = adminuser admin users = adminuser read list = adminuser write list = adminuser read only = No I also set the krb5.conf file to look like this: [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] default_realm = test.mycompany.com dns_lookup_realm = false dns_lookup_kdc = false ticket_lifetime = 24h forwardable = yes [realms] TEST.MYCOMPANY.COM = { kdc = dc.test.mycompany.com admin_server = dc.test.mycompany.com default_domain = test.mycompany.com } [domain_realm] dc.test.mycompany.com = test.mycompany.com .dc.test.mycompany.com = test.mycompany.com [appdefaults] pam = { debug = false ticket_lifetime = 36000 renew_lifetime = 36000 forwardable = true krb4_convert = false } I realize that there might be an issue with EXAMPLE.COM in there, however if I change it to TEST.MYCOMPANY.COM then it fails to join the domain with a preauthentication failure. As of 9/1/09, this is no longer the case.

  • How should I log time spent on multiple tasks?

    - by xenoterracide
    In Joel's blog on evidence based scheduling he suggests making estimates based on the smallest unit of work and logging extra work back to the original task. The problem I'm now experiencing is that I'll have create object A with subtask method A which creates object B and test all of the above. I create tasks for each of these that seems to be resulting in ok-ish estimates (need practice), but when I go to log work I find that I worked on 4 tasks at once because I tweak method A and find a bug in the test and refactor object B all while coding it. How should I go about logging this work? should I say I spent, for example, 2 hours on each of the 4 tasks I worked on in the 8 hour day?

  • How To Log Into The Desktop, Add a Start Menu, and Disable Hot Corners in Windows 8

    - by Chris Hoffman
    If you don’t have a touchscreen computer and spend all your time on the desktop, Windows 8’s new interface can seem intrusive. Microsoft won’t allow you to disable the new interface, but Classic Shell provides the options Microsoft didn’t. In addition to providing a Start button, Classic Shell can take you straight to the desktop when you log in and disable the hot corners that activate the charms and metro app switcher. There are other programs that do this, but Classic Shell is free and open-source. Many of the alternatives, such as Start8 and RetroUI, are commercial apps that cost money. We’ve covered Classic Shell in the past, but it’s come a long way since then. How Hackers Can Disguise Malicious Programs With Fake File Extensions Can Dust Actually Damage My Computer?
