  • Which tool / technology: System management for databases and dependent services

    - by Filburt
    I'm looking for advice on how to enable our team to take down and re-start our company systems for maintainance purposes. The scenario includes several Oracle db machines several MS SQL Server machines with multiple instances windows services (IIS etc.) BizTalk EAI solution Apache and Tomcat instances lots of scheduled tasks on win2003 and win2008 machines (physical and virtual). The main focus is on capture all dependencies between said databases and services and tasks connecting to them. At the moment an enterprise class solution is not an option. We are considering developing a solution driven by PowerShell scripts but I hope for some more suggestions.

  • ASP.NET - Manual authentication system

    - by Gal V
    Hello all, Wer'e developing an ASP.NET C# application, which will contain an authentication system that authenticates users in multiple levels (user, admin, super-admin, etc.). Our idea is NOT to use the built in ASP.NET forms authentication feature. Our plan is to create a whole 'new' system for it- based on the Session object, and SQL database contains users' info such as username & password. Is there any SERIOUS different between our idea to the Forms authentication feature? What security risks do we take? How do we solve them? Is this a good alternative for the forms authentication feature? Thanks in advance !

    - by unknown (google)
    I have BitDefender IS 2008 installed on my PC. In the last few days I have noticed the taskbar icon grumbling 1 issue requires your attention The Real-Time File Scanning is disabled and no amount of clicking "Fix" solved this issue. I have tried umpteen reboots and what have you. I really don't want to uninstall and re-install BitDefender (unless there's no other way out). How do I clear away the notification message?

  • Examples of how to visualize a versioning system?

    - by Alex Gilbert
    My shop is trying to formalize the release management process for an OSS product we maintain. It's a sort of a web development framework/CMS kind of thing, as in it's a product that other projects are built on top of. This makes clear communication about the versioning system especially critical for developers that are using the tool. I'm hoping to find some examples of how best to graph this system so we can communicate it better internally and with outside developers. I know there are lots of standards and best practices around versioning, so I'm hoping this extends to some sort of visual vocabulary as well. As one example, there is a nifty graph at http://en.wikipedia.org/wiki/Versioning#Software_Versioning_schemes. Are there any guides out there on how these sorts of things should be designed?

  • Document ranking strategy for P2P file sharing system.

    - by ablmf
    Recently, I got a task of building a P2P file sharing system. There is one requirement : the system should have a document ranking algorithm so that it could be used help users find more valuable files. Several strategy might be useful : force user to give a score to a file before it was downloaded The documents containing certain key words would get higher rank Manager could modify file ranking manually the more a file was downloaded, it would get a higher rank. Do you know any other strategy or methods that also appropriate? Or is there any real world example?

  • MVC Application Design

    - by Paul Brown
    Hello I am about to create my first proper application in ASP.NET MVC3. It is basically a jobs site with 3 levels: 1) Users - No registration and can view all jobs posted on the website 2) Posters - Need to register and login to post adverts 3) Admin - Need to register and login to post adverts and review postings before they go live Would you suggest I use the same Jobs controller for the three levels I mention above? With a LIST action to show jobs to "Users" and a CREATE & EDIT action for the "Posters" & "Admin"? Thanks Paul

  • HttpPostedFile.SaveAs() throws UnauthorizedAccessException even though the file is saved?

    - by jrummell
    I have an aspx page with multiple FileUpload controls and one Upload button. In the click handler I save the files like this: string path = "..."; for (int i = 0; i < Request.Files.Count - 1; i++) { HttpPostedFile file = Request.Files[i]; string fileName = Path.GetFileName(file.FileName); string saveAsPath = Path.Combine(path, fileName); file.SaveAs(saveAsPath); } When file.SaveAs() is called, it throws: System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. --- System.UnauthorizedAccessException: Access to the path '...' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode) at System.Web.HttpPostedFile.SaveAs(String filename) at Belden.Web.Intranet.Iso.Complaints.AttachmentUploader.btnUpload_Click(Object sender, EventArgs e) at System.Web.UI.WebControls.Button.OnClick(EventArgs e) at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace --- at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest() at System.Web.UI.Page.ProcessRequest(HttpContext context) at ASP.departments_iso_complaints_uploadfiles_aspx.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) Now here's the fun part.

  • Squid "system returned (13) Permission denied"

    - by AndyM
    I can get to a site form my Squid server directly using lynx http://my-URL , ie not using squid as the proxy, just to prove the connectivity exists. Lynx connects fine to the site - its a Weblogic portal When I try the same site from client with the squid machine as a proxy I get a squid error indicating that the destination site refused the connection from Squid. The squid server is a RHEL5.5 server. The error is something like The following error was encountered: Connection Failed The systen returned: (13) Permission denied Any ideas ? The squid access.log just indicates a TCP_MISS. Its as if the destinatin site knows its been accessed by squid and is not allowing ?

  • memory usage in C# (.NET) app is very high, until I call System.GC.Collect()

    - by Chris Gray
    I've written an app that spins a few threads each of which read several MB of memory. Each thread then connects to the Internet and uploads the data. this occurs thousands of times and each upload takes some time I'm seeing a situation where (verified with windbg/sos and !dumpheap) that the Byte[] are not getting collected automatically, causing 100/150MB of memory to be reported in task manager if I call System.GC.Collect() i'm seeing a huge drop in memory, a drop of over 100MB I dont like calling System.GC.Collect() and my PC has tons of free memory. however if anyone looks at TaskManager they're going to be concerned, thinking my app is leaking horribly. tips?

  • The great Vanishing Act of INetMgr.exe on my Windows 7 x64 system

    - by marc_s
    I'm facing an odd issue with the IIS Manager on Windows 7 (x64). At home, I have Win7 Professional, and when I check my IIS manager icon in the start menu, I see it links to %windir%\system32\inetsrv\InetMgr.exe When I launch this from the command line, it works like a charm. At work, however, I have Windows 7 Enterprise (x64), and when I check my link in the start menu, the entry is exactly the same. If I click on it - it works like a charm. Now if I'd like to launch it from the command line (cmd.exe or TakeCommand), however - the file just isn't there - a DIR %windir%\system32\inetsrv\*.exe shows a number of files, including a "inetmgr6.exe" - but no "inetmgr.exe" - and of course, I can't launch it either :-( Strangely enough, when I look at the directory %windir%\system32\INetSrv in Windows Explorer or Windows Powershell, I SEE the INetMgr.exe file and I can launch it - no problem. What the **** is going on here? How can I find the INetMgr.exe from my classic command line and launch it from there?? UPDATE: ok, some updates. On my work laptop, the INetMgr.exe file appears to really be located in a directory called c:\windows\syswow64\inetsrv (I'm recalling from memory, so don't quote me on the directory name - something like that). I can see this if I search for it in e.g. Powershell or Windows 7 Explorer. However, from a "classic" command line like cmd.exe, it appears to be in c:\windows\system32\inetsrv ..... hmmm.... trouble is - even though I now know where the file really is, I cannot access that directory from my classic command line - not even if I'm running cmd.exe as admin with elevated privileges....... so I know where the file is, but that still doesn't solve my problem :-(

  • Reliable Backup Solution for Linux for Complete System Restoration

    - by Chris S
    What's the best backup solution for Linux that can completely restore the entire filesystem to a blank harddrive (including partitioning) after an old harddrive dies? I'm currently running a few Ubuntu machines, some with RAID-1 and others without RAID (mostly laptops). I'd like to implement a backup solution that can take incremental snapshots of the entire filesystem, so that if I were to replace all the harddrives in a machine, I could use the backup to restore a perfect copy of the previous filesystem. Unfortunately, nearly all the backup solutions I've found seem to be glorified rsync scripts, which only backup some files, and have no easy way to restore once the entire filesystem is gone. Some of the more complicated solutions, like Bacula, might do what I need, but require a complicated server/client setup and are notoriously difficult to maintain. I've heard that Apple's TimeMachine utility has this ability, and I've had similar success taking differential disk images with Acronis True Image on Windows, but of course neither of these work on Linux. Is there anything comparable for Ubuntu?

  • Suggest the way to design several classes

    - by Oleg Tarasenko
    Hi, I'm building simple application on as3. Kind of starship game. What I want to do is to create several different star ships. Each one should have different images (different look), different sets of animation (e.g. when it's flying, burning, damaged), different kind of weapon and also different controllers (e.g. one can be managed by user, another one by computer, and I want to be able to reuse same ships for AI controller as well as for users controls). Each ship is created in the following way: Create entity Add spatial Add renderers Add other components.... ...... n. init the ship So what I am trying to do: 1) Create StarShip superclass, to store HP (as every ship has it), store spatial (same reason) 2) Create inherited class for any other ship... (It will contain renderer - (responsible for display part), weapon, set of animations), etc What do you think about such way of composition? Maybe it's better to place everything in super class, and then just create instances using long, long, long constructors like: StarShip(hp:HP, animations:DICT, weapon:Weapon, ....) Need advice

  • How to prevent Linux from deleting temporary files on shutdown

    - by Rajorshi
    Hi, I am using Ubutu 10.04. I have some apps that create a few temporary files in /tmp/<file> as part of their shutdown process. I want to inspect those files when the apps are closed in the event of a system shutdown. However, when the system comes up again I find that all temporary files have been deleted. How can I ask the system not to clear the files in /tmp/ on shutdown?

  • Why cant i install ANY operating system??

    - by Ranhiru
    I tested the memory and i tested the hard disk and everything is fine! Mini XP booted from Hirens Boot Disk works :( I tried Windows 7, Windows XP SP3 and even Ubuntu 10.04 :( All Operating Systems boots up to the point where they can load necessary files to start the OS and then resets the laptop Windows 7, only up to the point where the Windows Loading Animation is happening Ubuntu, only up to the point where the loading is done, shows a small screen and then goes to a blinking cursor and thats it... it keeps on blinking and sometimes resets the computer Windows XP SP3, loads all the drivers and everything and then the point where i should be able install the OS, it simply resets the laptop :( I have used the word reset instead of restart because the laptop completely turns off and then only turns back in Any solutions would be greatly appreciated

  • Finding how a hacked server was hacked

    - by sixtyfootersdude
    I was just browsing through the site and found this question: My server's been hacked EMERGENCY. Basically the question says: My server has been hacked. What should I do? The best answer is excellent but it raised some questions in my mind. One of the steps suggested is to: Examine the 'attacked' systems to understand how the attacks succeeded in compromising your security. Make every effort to find out where the attacks "came from", so that you understand what problems you have and need to address to make your system safe in the future. I have done no system admin work so I have no idea how I would start doing this. What would be the first step? I know that you could look in the server log files but as an attacker the first thing that I would do would be errasing the log files. How would you "understand" how the attacks succeeded?

  • JPA - Entity design problem

    - by Yatendra Goel
    I am developing a Java Desktop Application and using JPA for persistence. I have a problem mentioned below: I have two entities: Country City Country has the following attribute: CountryName (PK) City has the following attribute: CityName Now as there can be two cities with same name in two different countries, the primaryKey for City table in the datbase is a composite primary key composed of CityName and CountryName. Now my question is How to implement the primary key of the City as an Entity in Java @Entity public class Country implements Serializable { private String countryName; @Id public String getCountryName() { return this.countryName; } } @Entity public class City implements Serializable { private CityPK cityPK; private Country country; @EmbeddedId public CityPK getCityPK() { return this.cityPK; } } @Embeddable public class CityPK implements Serializable { public String cityName; public String countryName; } Now as we know that the relationship from Country to City is OneToMany and to show this relationship in the above code, I have added a country variable in City class. But then we have duplicate data(countryName) stored in two places in the City class: one in the country object and other in the cityPK object. But on the other hand, both are necessary: countryName in cityPK object is necessary because we implement composite primary keys in this way. countryName in country object is necessary because it is the standard way of showing relashionship between objects. How to get around this problem?

  • How should I perform database maintenance on a 24x7 system

    - by solublefish
    I'm a software developer who inherited a part-time DBA role. I'm responsible for an application backed by a small, high-volume 24x7 database on SQL Server 2008. While there's other stuff in the DB, the critical piece is a 50GB, 7.5M row table that serves 100K requests/sec during peak load, and about half that at "night". This is 99%+ read traffic, but the writes are constant, and required. I need to be able to perform periodic maintenance without a maintenance window. Say an index rebuild, a job to purge old data, Windows Update, or hardware upgrade. Most of the advice I've seen is along the lines of "MAKE a maintenance window." While I appreciate the sentiment, I hope there's another way. If it will solve this problem, I do have the ability to purchase new hardware or modify the database, the clients (a set of web services servers), and much of the application code (ADO.NET + ASP.NET). I've been thinking along the lines of using the warm spare (or a 3rd server) to do the maintenance, and then "swap" it into production. 1 Synchronize the spare by restoring backups, including a current transaction log. 2 Perform the maintenance tasks. 3 Reconfigure clients to connect to the spare server. Existing connections are finished within a minute or so. 4 The spare server is now the production server. The problem remaining is that the new production server is now out of date by however long it took to perform maintenance. Is there some way that the original production server can be made to queue up changes and merge them to the spare between steps 2 and 3? Any other ideas?
