  • Is it possible to use a static IP assigned by my ISP for an offsite web server on a VPS (different ISP)?

    - by NightOwl888
    I have a web server on a Virtual Private Server with a hosting provider. Unfortunately, they are really stingy with IP addresses and I need to run several SSL certificates on my server, so I will need a few more than I have. I have a block of 5 static IP addresses on a business package through a different ISP and I am only using 1 of them for connectivity in the office. What I am wondering is if it is possible to use the 4 unused static IP addresses from this ISP on my VPS, which is hosted by another ISP? The VPS (web server) is running Windows Server 2008 R2 Web Edition. If this can be done, please let me know how to configure it.

  • Max tcp/ip connections on Windows Server 2008

    - by zendar
    I have .Net service that listens on single port over TCP protocol. Clients connect and then transmit data for some time (from few minutes to several hours). Is there any limit on number of connections on Windows 2008 server? I did not hit any, since now there is up to 50 users. Plan is to have thousands of users, so I'd like to know if there will be problems in future. Edit: As Cloud answered, it seems that there are some limits in some versions of Windows Server 2008. Is there any reference on those limits? I tried Google, but it returns articles on limit on half-bound tcp connections.

  • How to cope with null results in SQL Tasks that return single rows in SSIS 2005?

    - by JSacksteder
    In a dataflow task, I can slip a rowcount into the processing flow and place the count into a variable. I can later use that variable to conditionally perform some other work if the rowcount was 0. This works well for me, but I have no corresponding strategy for sql tasks expected to return a single row. In that event, I'm returning those values into variables. If the lookup produces no rows, the sql task fails when assigning values into those variables. I can branch on that component failing, but there's a side effect of that - if I'm running the job as a SQL server agent job step, the step returns DTSER_FAILURE, causing the step to fail. I can tell the sql agent to disregard the step failure, but then I won't know if I have a legitimate error in that step. This seems harder than it should be. The only strategy I can think of is to run the same query with a count(*) aggregate and test if that returns a number 0 and if so running the query again without the count. That's ugly because I have the same query in two places that I need to keep in sync. Is there a better way?

  • One vs. many domain user accounts in a server farm

    - by mjustin
    We are in a migration process of a group of related computers (Intranet servers, SQL, application servers of one application) to a new domain. In the past we used one domain user account for every computer (web1, web2, appserver1, appserver2, sql1, sqlbackup ...) to access central Windows resources like network shares. Every computer also has a local user account with the same name. I am not sure if this is necessary, or if it would be easier to configure and maintain to use one domain user account. Are there key advantages / disadvantages of having one single user account vs. dedicated accounts per computer for this group of background servers? If I am not wrong, one advantage besides easier administration of the user account could be that moving installed applications and services around between the computers does not require a check of the access rights anymore. (Except where IP addresses or ports are used)

  • Do database engines other than SQL Server behave this way?

    - by Yishai
    I have a stored procedure that goes something like this (pseudo code) storedprocedure param1, param2, param3, param4 begin if (param4 = 'Y') begin select * from SOME_VIEW order by somecolumn end else if (param1 is null) begin select * from SOME_VIEW where (param2 is null or param2 = SOME_VIEW.Somecolumn2) and (param3 is null or param3 = SOME_VIEW.SomeColumn3) order by somecolumn end else select somethingcompletelydifferent end All ran well for a long time. Suddenly, the query started running forever if param4 was 'Y'. Changing the code to this: storedprocedure param1, param2, param3, param4 begin if (param4 = 'Y') begin set param2 = null set param3 = null end if (param1 is null) begin select * from SOME_VIEW where (param2 is null or param2 = SOME_VIEW.Somecolumn2) and (param3 is null or param3 = SOME_VIEW.SomeColumn3) order by somecolumn end else select somethingcompletelydifferent And it runs again within expected parameters (15 seconds or so for 40,000+ records). This is with SQL Server 2005. The gist of my question is this particular "feature" specific to SQL Server, or is this a common feature among RDBMS' in general that: Queries that ran fine for two years just stop working as the data grows. The "new" execution plan destroys the ability of the database server to execute the query even though a logically equivalent alternative runs just fine? This may seem like a rant against SQL Server, and I suppose to some degree it is, but I really do want to know if others experience this kind of reality with Oracle, DB2 or any other RDBMS. Although I have some experience with others, I have only seen this kind of volume and complexity on SQL Server, so I'm curious if others with large complex databases have similar experience in other products.

  • Server side alerts for client side app

    - by jpwagner
    Here's the scenario: User interacts with Adobe flex webpage to configure reports based on some data stored server side. They configure their view and have THAT view emailed to them daily. I've got the report builder, the part I'm trying to figure out is how to render the report server side and send it out as email (native flex functionality? convert to html? take screenshot? assume something is running client side?...) Please help me with some ideas. Thanks!

  • How can I sync a database driven website to a different server

    - by tbrandao
    I have a website using cPanel on a dedicated account, I would like to be able to automatically sync the website to a second hosting company or perhaps to a local (in house ) server. Basically this is a type of replication. The website is database driven (MySQL), so Ideally it would sync everything (content, database, emails etc.) , but most importantly is syncing the website files and its database. I'm not so much looking for a fail-over solution as an automatic replication solution, so if the primary site (Server) goes off-line, I can manually bring up the replicated site quickly. I'm familiar with tools like unison and rsync, but most of these only sync file(s) and do not do too well with open database connections.

  • Best protocol for client/server communication, from PHP/Perl to C++/Qt4

    - by Kyle
    I'm the author of an Open Source kiosk management system, Libki. The current version, though functional, was very much a learning experience for me. I'm working on a complete rewrite and am having a hard time deciding what protocol to use. The server will be written in PHP or Perl. Most likely PHP because I need to support some uncommon protocols that Library software use, ( SIP and NCIP ). So far I've only found a SIP2 library in PHP. The client is written in C++/Qt4. I'm looking at RPC and REST for client/server communication. I've found RPC client libraries for Qt4, and REST is already part of the Qt4 libraries. Is there an alternative I've missed? So far, REST seems to be the winner.

  • sql statement question. Need to query 3 tables in one go!

    - by Stefan
    Hey there, I have an sql database. In this database is 3 tables I need to query. The first table has all the item info called item and the other two tables has data for votes and comments called userComment and the third for votes called userItem I currently have a function which uses this sql query to get the latest more popular (in terms of both votes and comments): $sql = "SELECT itemID, COUNT(*) AS cnt FROM ( SELECT `itemID` FROM `userItem` WHERE FROM_UNIXTIME( `time` ) >= NOW() - INTERVAL 1 DAY UNION ALL SELECT `itemID` FROM `userComment` WHERE FROM_UNIXTIME( `time` ) >= NOW() - INTERVAL 1 DAY AND `itemID` > 0 ) q GROUP BY `itemID` ORDER BY cnt DESC"; I know how to change this for either by votes alone or comments.... HOWEVER - I need to query the database to only return the itemID's of the ones which have specific conditions in only the item table these are WHERE categoryID = 'xx' AND typeID = 'xx' If the sql ninja could please help me on this one? Do I have to first return the results from the above query and the for each in the array fetched then check each against the item table and see if it fits the conditions to build a new array - or is that overkill? Thanks, Stefan

  • Windows Server 2008 R2 Service Pack 1 issue

    - by saj
    Net 4.0 websites running on a Windows Server 2008 R2 server using IIS 7.0. The websites allows Single Sign on via an encrypted token passed in a query string e.g. www.mywebsite.com?token=1159CE30A4ED1148E86D779AC7A1CF4DC75CCEC7213401D13CA181A2ED1C29A8. However, after installing Service Pack 1; SSO has stopped working and the website redirects to www.mywebsite.com. The redirect occurs before any code is hit. No idea what is causing this and any ideas would be much appreciated.

  • How can I retrieve a MS SQL Express Database from a non-booting computer?

    - by Redandwhite
    A client has a very important database that has not been backed up in 6 months. The PC has promptly failed. The Windows directory is corrupt, and the computer will not boot. It had a Microsoft SQL Server Express 2005 database on it. I have access to the hard drive by booting in with an Ubuntu Live CD, but I am not sure if I can find the database. I am not sure what I am looking for, or where to look either. The dead machine had Windows XP on it.

  • Windows 2008 Server on VMWare (hardware)

    - by Bill
    I want to setup a single server to run a few virtual servers for our datacenter. I do not have a lot of money to spend so I am trying to gain bang for the buck. My budget is around $2,000. So I was thinking about building the following as the VMWare physical server: Intel iCore 7 950 (LGA1366, 4 cores,8 threads) Gigabyte GA-X58-USB3 LGA 1366 X58 ATX Intel Motherboard 24 GB of Viper II Series, Sector 7 Edition, Extreme Performance DDR3-1600 (PC3-12800) CL9 Triple Channel Memory VelociRaptor 300GB 10,000 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive I am planning on running the newest version of VMWare ESXi (64-bit). On these I am planning on running a few various servers: Windows 2008 Server R2 w/ IIS (several custom built ASP.NET Apps) Windows 2008 Server R2 w/ MS SQL 2008 Database Server Linux Web Server w/ Several WordPress Blogs (XAMPP?) Windows 2008 Server R2 w/ IIS (DEV ENVIRONMENT) Windows 2008 Server R2 w/ MS SQL 2008 Database Server (DEV ENVIRONMENT) In your opinion, will this hardware be sufficient to run the above load with room for possible 2-3 more virtual machines (probably lightweight web servers)?

  • Is there a way to load an existing connection string for Linq to SQL from an app.config file?

    - by Brian Surowiec
    I'm running into a really annoying problem with my Linq to SQL project. When I add everything in under the web project everything goes as expected and I can tell it to use my existing connection string stored in the web.config file and the Linq code pulls directly from the ConfigurationManager. This all turns ugly once I move the code into its own project. I’ve created an app.config file, put the connection string in there as it was in the web.config but when I try to add another table in the IDE keeps forcing me to either hardcode the connection string or creates a Settings file and puts it in there, which then adds a new entry into the app.config file with a new name. Is there a way keep my Linq code in its own project yet still refer back to my config file without the IDE continuously hardcoding the connection string or creating the Settings file? I’m converting part of my DAL over to use Linq to SQL so I’d like to use the existing connection string that our old code is using as well as keep the value in a common location, and one spot, instead of in a number of spots. Manually changing the mode to WebSettings instead of AppSettings works untill I try to add a new table, then it goes back to hardcoding the value or recreating the Settings file. I also tried to switch the project type to be a web project and then rename my app.config to web.config and then everything works as I’d like it to. I’m just not sure if there are any downfalls to keeping this as a web project since it really isn't one. The project only contains the Linq to SQL code and an implementation of my repository classes. My project layout looks like this Website -connectionString.config -web.config (refers to connectionString.config) Middle Tier -Business Logic -Repository Interfaces -etc. DAL -Linq to SQL code -Existing SPROC code -connectionString.config (linked from the web poject) -app.config (refers to connectionString.config)

  • Running two Magentos installations, one of which has 3 stores set up as multi-store. Which server?

    - by Pedro Peixoto
    I want to run 4 Magento stores in 2 different installations. 1 is a standalonne installation with 3 languages. The other is a multi-store with 3 different online stores in different domains. At the moment we have a VPS with 1GB memory, would that be enough? I ask because I've finished the standalone store and already put it online, and the server is already running on 62% memory. The ideal would be that this is enough as my company wouldn't like to move to a Dedicated Server (as it involves costs). I'm sure I can try to optimize Magento to run on lower memory (I'm expecting visits averaging 2000/day on all sites), if I could have some tips on the best way to do that Id appreciate it too.

  • How can I concisely copy multiple SQL rows, with minor modifications?

    - by Steve Jessop
    I'm copying a subset of some data, so that the copy will be independently modifiable in future. One of my SQL statements looks something like this (I've changed table and column names): INSERT Product( ProductRangeID, Name, Weight, Price, Color, And, So, On ) SELECT @newrangeid AS ProductRangeID, Name, Weight, Price, Color, And, So, On FROM Product WHERE ProductRangeID = @oldrangeid and Color = 'Blue' That is, we're launching a new product range which initially just consists of all the blue items in some specified current range, under new SKUs. In future we may change the "blue-range" versions of the products independently of the old ones. I'm pretty new at SQL: is there something clever I should do to avoid listing all those columns, or at least avoid listing them twice? I can live with the current code, but I'd rather not have to come back and modify it if new columns are added to Product. In its current form it would just silently fail to copy the new column if I forget to do that, which should show up in testing but isn't great. I am copying every column except for the ProductRangeID (which I modify), the ProductID (incrementing primary key) and two DateCreated and timestamp columns (which take their auto-generated values for the new row). Btw, I suspect I should probably have a separate join table between ProductID and ProductRangeID. I didn't define the tables. This is in a T-SQL stored procedure on SQL Server 2008, if that makes any difference.

  • Zend Server CE Apache mod_rewrite REQUEST_FILENAME SCRIPT_FILENAME Problem

    - by liumiuyong
    Hi,there! I use this .htaccess file in a project: RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1 [L] It works well in Apache 2.2 Recently I started to use Zend Server CE , the ReWrite Rule didn't work ! And this works: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1 [L] This is what Apache's document say: The variables SCRIPT_FILENAME and REQUEST_FILENAME contain the same value - the value of the filename field of the internal request_rec structure of the Apache server. The first name is the commonly known CGI variable name while the second is the appropriate counterpart of REQUEST_URI (which contains the value of the uri field of request_rec). Anyone can figure out why? Appreciate!

  • Problems with Database Search Code (asp.net vb)

    - by Phil
    Here is a sample of my database search code: Dim sql As String = "Select * From Table Where " Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim andor As Boolean = AndOr1.SelectedValue 'selection can be AND or OR (0 / 1) 'Code for when the user selects AND If NameSearch.Text.ToString IsNot String.Empty And andor = 0 Then sql += "Surname LIKE '%" & name & "%' AND " End If If EmailSearch.Text.ToString IsNot String.Empty And andor = 0 Then sql += "Email LIKE '%" & email & "%' AND " End If If CitySearchBox.Text.ToString IsNot String.Empty And andor = 0 Then sql += "City LIKE '%" & city & "%' AND " End If 'Code for when the user selects OR If NameSearch.Text.ToString IsNot String.Empty And andor = 1 Then sql += "(Surname LIKE '%" & name & "%' OR " End If If EmailSearch.Text.ToString IsNot String.Empty And andor = 1 Then sql += "Email LIKE '%" & email & "%') OR " End If If CitySearchBox.Text.ToString IsNot String.Empty And andor = 1 Then sql += "(City LIKE '%" & city & "%' OR " End If sql = CleanString(sql) End Sub When the user selects AND (as andor.selectedvalue(0)) then the sql is produced fine like this; Select * From Table Where Surname LIKE '%test%' AND Email LIKE '%test%' AND City LIKE '%test%' But if the user selects OR (as andor.selectedvalue(1)), nothing is outputted except; Select * From Table Where Im sure the controls have values so are not string.empty and when the user selects OR the correct value 1 is being assigned to andor.

  • Identity alternative for SQL Azure Federation : are Azure Queues or Service Bus Queues a good choice?

    - by JYL
    As many of developers, I'm looking for a way to integrate my existing app to SQL Azure Federations, and replacing the Identity columns (the primary keys of my tables) is a big problem. For many reasons, I do NOT want use GUID for my primary keys (please don't open the debate about the GUID or not, it's not my question : i just don't want a GUID, period). So I need to build a key provider to replace the "identity" feature of a standard SQL database. I'm using Entity Framework, so i can easily find one place to set the Id value just before the insert (by overriding the SaveChanges method of my ObjectContext class). I just need to find a "not too complicated" implementation for getting the current Id, which is "farm-ready". I've read this SO post : "ID Generation for Sharded Database (Azure Federated Database)" and "Synchronizing Multiple Nodes in Windows Azure from MSDN Magazine", but this solution sounds a bit complicated for me. I'm thinking about creating (automatically) one azure queue for each SQL table, which contain a pre-loaded list of consecutive integer. When I want an Id value, I just have to get a message from the queue (which becomes invisible and is deleted on the way), which give me the current available Id. About the choice between "Windows Azure Queues" and "Windows Azure Service Bus Queues", I prefere "Windows Azure Queues", due to the "high" latency of Service Bus Queues. I don't think that the lack of "ordering garantee" of Azure Queues is a problem. What do you think about that idea of using Azure Queues to provide Id values ? Do you see any argument to give up that idea ? Do you have a better idea, or even a good practice, to provider integer ids in SQL Azure Federation databases ? Thanks.

  • m and s keys do not work over vnc connection to ubuntu server

    - by Don
    I'm new at setting a lot of this up, so bear with me. I installed Ubuntu 10.4 server on a 64 bit machine. Then I added vnc so I could manage it while it's racked. I start the server, SSH to it, and run vncserver :1 At this point, all keys work fine. Next I exit out of the SSH session and fire up my client vnc app. I connect via the IP :1, enter my password, and everything seems to be fine. Now when I enter a terminal (through the vnc connection) I cannot type lowercase "s" or "m" (upper case works). I've tried on two different pc's running the vnc client, but it's the same. I also installed the latest updates from Ubuntu as of today. Thanks for any help.
