  • Applying iterative algorithm to a set of rows from database

    - by Corvin
    Hello, this question may seem too basic to some, but please bear with be, it's been a while since I dealt with decent database programming. I have an algorithm that I need to program in PHP/MySQL to work on a website. It performs some computations iteratively on an array of objects (it ranks the objects based on their properties). In each iteration the algorithm runs through all collection a couple of times, accessing various data from different places of the whole collection. The algorithm needs several hundred iterations to complete. The array comes from a database. The straightforward solution that I see is to take the results of a database query and create an object for each row of the query, put the objects to an array and pass the array to my algorithm. However, I'm concerned with efficacy of such solution when I have to work with an array of several thousand of items because what I do is essentially mirror the results of a query to memory. On the other hand, making database query a couple of times on each iteration of the algorithm also seems wrong. So, my question is - what is the correct architectural solution for a problem like this? Is it OK to mirror the query results to memory? If not, which is the best way to work with query results in such an algorithm? Thanks!

  • Prevent cached objects to end up in the database with Entity Framework

    - by Dirk Boer
    We have an ASP.NET project with Entity Framework and SQL Azure. A big part of our data only needs to be updated a few times a day, other data is very volatile. The data that barely changes we cache in memory at startup, detach from the context and than use it mainly for reading, drastically lowering the amount of database requests we have to do. The volatile data is requested everytime by a DbContext per Http request. When we do an update to the cached data, we send a message to all instances to catch a fresh version of all the data from the SQL server. So far, so good. Until we introduced a bug that linked one of these 'cached' objects to the 'volatile' data, and did a SaveChanges. Well, that was quite a mess. The whole data tree was added again and again by every update, corrupting the whole database with a whole lot of duplicated data. As a complete hack I added a completely arbitrary column with a UniqueConstraint and some gibberish data on one of the root tables; hopefully failing the SaveChanges() next time we introduce such a bug because it will violate the Unique Constraint. But it is of course hacky, and I'm still pretty scared ;P Are there any better ways to prevent whole tree's of cached objects ending up in the database? More information Project is ASP.NET MVC I cache this data, because it is mainly read only, and this saves a tons of extra database calls per http request

  • Using design-patterns to transform web-service model classes into local model classes and vise versa

    - by Daniil Petrov
    There is a web-application built with play framework 1.2.7. It contains less than 10 model classes. The main purpose of the application is a lightweight access to a complex remote application (more than 50 model classes). The remote application has its own SOAP API and we use it for synchronization of data. There is a scheduled job in the web-app which makes requests to the remote app. It gets bunches of objects from the remote model and populates corresponding objects of the local model. Currently, there are two groups of classes - the local model and the remote model (generated from wsdl schema). It is not allowed to make any modifications to the remote model. Transformations are being made in the scheduled job class. When it gets objects from the remote app it creates local objects. Recently, it was decided to add a possibility to modify the remote objects. It requires more transformations on our side. We need to transform from remote to local model when reading objects and from local to remote when changing objects. I wonder if this would be possible to use some design-patterns to reduce a number of transformations?

  • Is there any alternative to TeamViewer VPN? [closed]

    - by Dzmitry Lahoda
    TeamViewer VPN connection mode lets you create a virtual private network (VPN) between two TeamViewer computers. Two computers connected via VPN act as in a common network. This allows you to access the resources of your partner's computer and vice versa. What other programs can do the same thing? EDIT I made VPN connection using TeamViewer. But Test ping button opens console where I just see "destination host is unreachable" or "request timed out".

  • Need a solution to store images (1 billion, 1000,000,000) which users will upload to a website via php or javascript upload [on hold]

    - by wish_you_all_peace
    I need a solution to store images (1 billion) which users will upload to a website via PHP or Javascript upload (website will have 1 billion page views a month using Linux Debian distros) assuming 20 photos per user maximum (10 thumbnails of size 90px by 90px and 10 large, script resized images of having maximum width 500px or maximum height 500px depending on shape of image, meaning square, rectangle, horizontal, vertical etc). Assume this to be a LEMP-stack (Linux Nginx MySQL PHP) social-media or social-matchmaking type application whose content will be text and images. Since everyone knows storing tons of images (website users uploaded images in this case) are bad inside a single directory or NFS etc, please explain all the details about the architecture and configuration of the entire setup of storage solution, to store 1 billion images on any method you recommend (no third-party cloud storage like S3 etc. It has to be within the private data center using our own hardware and resources.). The solution has to include both the storage solution and organizing the images uploaded by users. How will we organize the users images if a single user will not have more than 20 images (10 thumbs and 10 large of having either width or height 500px)? Please consider that this has to be organized in a structural way so we can fetch a single user's images via PHP/Javascript or API programmatically through some type of user's unique identifier(s).

  • SQL Server 2008 uses half the CPU’s

    - by ACALVETT
    I recently got my hands on a couple of 4 socket servers with Intel E7-4870's (10 cores per cpu) and with hyper threading enabled that gave me 80 logical CPU's. The server has Windows 2008 R2 SP1 along with SQL 2008 (Currently we can not deploy SQL 2008 R2 for the application being hosted). When SQL Server started I noticed only 2 NUMA nodes were configured and 40 logical cores where there should have been 4 NUMA nodes and 80 logical cores (see below). The problem is caused by that fact that...(read more)

  • Why the “Toilet” Analogy for SQL might be bad

    - by Jonathan Kehayias
    Robert Davis(blog/twitter) recently blogged The Toilet Analogy … or Why I Never Recommend Increasing Worker Threads , in which he uses an analogy for why increasing the value for the ‘max worker threads’ sp_configure option can be bad inside of SQL Server.  While I can’t make an argument against Robert’s assertion that increasing worker threads may not improve performance, I can make an argument against his suggestion that, simply increasing the number of logical processors, for example from...(read more)

  • "Not enough memory" error when running Peachtree Accounting 2010 with Logmein

    - by Justin Bowers
    I setup one of my clients with a Logmein Pro account recently and everything has been running fine so far. Today, however, my client received an error when they were logged into their work computer remotely and tried to run a report from Peachtree Accounting 2010. The error states: "Not enough memory to run" and she can't print the report. I looked online and found another user that had this same problem with Peachtree 2010 when connected via Logmein here. The error doesn't happen if the user runs the report while sitting at her work computer, but it always happens when connected via Logmein. I know most of you will push it off as just a Logmein issue, which I'm sure it is - but I would like any constructive input from anyone else who may have had the same or similar problem. Thanks, Justin

  • How to prevent question mark cursor issue cause be Insert key when doing VNC to a mac?

    - by Sorin Sbarnea
    I found out that when I press the Insert key on the client I will block the OS X VNC server by putting it in a "help mode" where you get the question mark mouse cursor. The mouse works but I cannot use the keyboard anymore. Details: Reconnecting using VNC does not help Normal keyboard is working fine on the mac The only solution in addition to relogin was to stop the VNC server on mac using: killall OSXvnc-server After few seconds it will restart by itself and it will work. I don't like current workaround and looking for something better. Tested with these versions of the VNC client and all put the VNC server in the question mark mode, requiring service restart: Ultr@VNC 1.0.8.2 RealVNC 4.1.3 I know that the problem is caused by the different/bad implementation of the VNC protocol in the server but do you need an workaround?

  • Backup and Restore ADAM database

    - by kuoson
    Hi, I was trying to backup and restore an ADAM database to a different server the other day. I copied all files under "Program Files/Microsoft ADAM" folder to the same path in the destination server and started the ADAM service in the destination server up. Although the service come back up successfully and I was able to connect to the instance with ADAM ADSI Edit mmc snap-in, I found I had to reset every single user's password before they can login again. Has anyone got this issue before? Is the password encrypted with the server IP address or something like that?

  • Usability Problems with RDP and Dual Monitors

    - by Stung
    Hi All, When I RDP into a win2k3 machine with the dual mon settings, I've noticed that there are a couple of usability problems: 1) Dialog boxes are popped up right in the middle of both monitors making it hard to read. 2) Windows are maximized to both monitors instead of just one. 3) The task bar spans across two monitors. (This is just a matter of preference. I prefer my task bar to span across just my primary monitor) I know that Splitview is a good tool that solves all these problems, but there's a price-tag to it. To be fair, $39 for a tool like this is not too bad at all. However, before I suggest this tool to my team and manager to get the licenses for it, are there any free alternatives that will solve the 3 above problems? -Steve

  • How to use Salt Stack with minions all behind NAT (not publicly accessible, default salt ports not open)?

    - by MountainX
    Can Salt Stack minions communicate with the salt master from behind NAT/Firewalls, etc., using standard ports that would be open be default in all consumer NAT routers (and without the minions having a public DNS record or static IP)? I'm working my way through my first salt tutorial, and this is where I'm stuck. I am able to configure iptables on the Ubuntu salt-master. But I have no control over the routers/NAT that the minions will sit behind. So far I tried these settings: /etc/salt/master: publish_port: 465 ret_port: 443 /etc/salt/minion: master_port: 465 That did not work. Background: I have a custom developed application presently running on about 40 Kubuntu laptops (& more planned). Every few months I have to update the application. (Often this just amounts to replacing a .jar file, which requires root permissions.) I also have to run Ubuntu updates and a few other minor things. I've been doing it manually, one by one, using Team Viewer to log into each client. I would like to dramatically improve this process. The two options I'm aware of are either: use reverse ssh tunnels and bash scripts. I tested this and it works. But I don't get any of the reporting, etc., I would get with Salt Stack. use Salt Stack (or similar) management tool. But I need a really simple tool. I can't invest any time in a big learning curve. I looked at Puppet and a bunch of related tools. The only one I found that looked simple enough for me (so far) was Salt Stack. But I'm stuck now because my minion can't reach the salt-master, as stated above. I appreciate suggestions.

  • hosting database on separate server

    - by Amit Aggarwal
    Hello Experts, We have an enterprise web app to which our clients post/upload lots of documents [mainly images and pdf files] via web interface, iphone app etc etc. We are also using imagick to split pdf documents into images. Also, large number of mysql SELECT/UPDATE/DELETE queries happen all day. Currently, all of this is happening on same server and we are planning to split the process in 3 stages : 1) a server only for database 2) a server only for documents (document upload, splitting etc) 3) a server for the main php web app Is there any drawback with this kind of structure as compared to hosting everything on same server ? Please guide. Thanks, Amit

  • Document, Document, Document

    - by AllenMWhite
    A while back I blogged about using Checklists , but there's another task you want to incorporate into your workflow - documentation. Now, I'm not just talking about documenting the logic, system flow and data and structure changes, I'm also talking about documenting your daily activities (commonly referred to as a journal.) It's amazing how useful a private journal can be when you need to revisit the thought process you went through to develop the processes you're implementing. I'm also talking about...(read more)

  • SQL Error: -443, SQLState: 38111 when accessing table metadata on DB2 zOS

    - by snowflake
    Hello, I'm getting following error when using Hibernate in a Java application over my DB2 database. This error occurs with one DB2 database and not with another (I'm almost sure the problem is in DB2 server side configuration), and I didn't found the difference between the two databases. The SQL error -443 is missing from the documentation I found: http:// rikipedia.co.za/index.php/DB2_SQL_Error_Codes (one link maximum per question due to reputation) According to following link, the 111 part of the sql state 38111 would indicate the reason of the failure. http://www.sqlerror.de/db2_sql_error_-443_sqlstate_42724.html Any idea ?

  • Programming logic to group a users activities like facebook. E.g. Chris is now friends with A, B and C

    - by Chris Dowdeswell
    So I am trying to develop an activity feed for my site, Basically If I UNION a bunch of activities into a feed I would end up with something like the following. Chris is now friends with Mark Chris is now friends with Dave What I want though is a neater way of grouping these similar posts so the feed doesn't give information overload... E.g. Chris is now friends with Mark, Dave and 4 Others Any ideas on how I can approach this logically? I am using Classic ASP on SQL server. Here is the UNION statement I have so far... SELECT U.UserID As UserID, L.UN As UN,Left(U.UID,13) As ProfilePic,U.Fname + ' ' + U.Sname As FullName, 'said ' + WP.Post AS Activity, WP.Ctime FROM Users AS U LEFT JOIN Logins L ON L.userID = U.UserID LEFT OUTER JOIN WallPosts AS WP ON WP.userID = U.userID WHERE WP.Ctime IS NOT NULL UNION SELECT U.UserID As UserID, L.UN As UN,Left(U.UID,13) As ProfilePic,U.Fname + ' ' + U.Sname As FullName, 'commented ' + C.Comment AS Activity, C.Ctime FROM Users AS U LEFT JOIN Logins L ON L.userID = U.UserID LEFT OUTER JOIN Comments AS C ON C.UserID = U.userID WHERE C.Ctime IS NOT NULL UNION SELECT U.UserID As UserID, L.UN As UN,Left(U.UID,13) As ProfilePic, U.Fname + ' ' + U.Sname As FullName, 'connected with <a href="/profile.asp?un='+(SELECT Logins.un FROM Logins WHERE Logins.userID = Cn.ToUserID)+'">' + (SELECT Users.Fname + ' ' + Users.Sname FROM Users WHERE userID = Cn.ToUserID) + '</a>' AS Activity, Cn.Ctime FROM Users AS U LEFT JOIN Logins L ON L.userID = U.UserID LEFT OUTER JOIN Connections AS Cn ON Cn.UserID = U.userID WHERE CN.Ctime IS NOT NULL

  • Remotely set VNC service password

    - by FreshCode
    After a Windows update I cannot connect to a Windows Server 2008 machine via RDP. As an alternative, I remotely installed UltraVNC using PsExec. The WinVNC service starts successfully but when I try to connect remotely, I receive the following error message: This server does not have a valid password enabled. Until a password is set, incoming connections cannot be enabled. Since I don't have desktop access to the machine, how do I set the password?

  • Can connect through Watchguard mobile VPN, but can't ping or access network drives

    - by johnnyb10
    We're having any issue in which some of our employess can no longer connect to our network drives when out of the office. We use Watchguard Mobile VPN (we have a Watchguard Firebox firewall) and the users are able to connect. That is, their status in the the VPN client says "Connected" and they have the correct IP address listed as the VPN Endpoint. The problem is, when they try to map drives, or even ping the IP address of a server on our network, it fails. Last week, we temporarily switched one of our Comcast modems to our backup DSL modem because the Comcast was accidentally shut off by Comcast, and the problem seemed to start around then. We've since switched back and the problem persists, so that doesn't seem to have been it (which makes sense). But we also made other changes at the time that might have thrown something off, although we feel like we've checked them all. Plus, some people can successfully connect to network drives through the VPN. Can someone please suggest some steps to help troubleshoot? We've checked the policies on our Watchguard box, and they seem fine. We've looked at the settings on the Mobile VPN client, but nothing seems like a probable cause. Thanks.

  • Can't RDP Into Windows Server After Windows Server Establishes VPN Session

    - by Jennifer Baker
    Hi there. I've setup a Windows 2008 Server in a Cloud Environment. I am able to RDP to this Windows Server ("aka CloudServer") in the Cloud Environment. When I establish PPTP VPN connection from the CloudServer back to our Windows Server ("aka OfficeServer"), my RDP session is dropped and it won't let me RDP back in. The only way how I can RDP to the CloudServer is using the DHCP ip address issued from the OfficeServer. What do I need to change on the CloudServer? Thanks in advance for your help! Jennifer
