  • SQL Server authentication - limit access to database to only connect through application

    - by Mauro
    I have a database which users should not be able to alter data in unless they use the specific app. I know best practice is to use windows authentication however that would mean that users could then connect to the database using any other data enabled app and change values which would then not be audited. Unfortunately SQL 2008 with its inbuilt auditing is not available. Any ideas how to ensure that users cannot change anything unless its through the controlling app?

  • Sparing level on HP EVA 4000

    - by Samuel
    One of the disks of our EVA4000 died today. This diskgroup (all volumes vraid5 with sparing level 1 and almost no space left for more volumes, 1TiB drives) is being rebuilt with "spare space" right now, and it will take at least 15 hours to do the leveling/rebuilding. We can't get a new disk until Friday. So, the question is, what would happen if another disk dies before the leveling completes? Would we lose data? And after that, how many aditional disks could die before losing data? 1 or 2? In "usual" RAID, we would be vulnerable to data loss while the rebuild takes place, but in this case the space reserved for sparing is two times the size of the bigger disk, so at the very least the effect should be the same of having two spares. Thanks in advance. Update: I have found some interesting threads about this question but still can't answer to this question, so I'm starting a bounty. http://blog.thestoragearchitect.com/2008/10/27/understanding-eva/ http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&url=http%3A%2F%2Fwww.experts-exchange.com%2FStorage%2FStorage_Technology%2FQ_25548177.html (Expert Exchange question from google).

  • SQL Server Offsite Backups

    - by Eric Maibach
    We have about !TB of SQL Server databases, and these databases generate about 200GB of data changes each day. Up to this point we have been doing Weekly full backups, daily diff backups, and hourly transaction log backups. The full and diff backups are backed up to tape and taken offsite each day. We have been trying to move away from tapes, and our IT department purchased a Barracuda Backup device that backups up data and then sends it offsite using our internet connection. I have been trying to get this to work for our SQL Server backups, and have ran into a number of problems. I normally like to just use SQL Server to perform backups instead of trying to use a agent, so that is what I tried first. However the Barracuda device was not able to dedup these files very well, so it ended up being to much data to try to send offsite and to archive. I then tried installing the Barracuda agent and using it to backup the SQL Server databases. However the problem I am having there is that on some of the database servers I also have files that need backed up, and I cannot find a way to create seperate backup schedules for the file backups and the SQL Server backups. Barracuda only does full or transaction log backups. So if I want to do hourly transaction log backups I end up doing a file system backup every hour (which is not good), or if I only schedule the backups to run once a night I either have to do a full backup every night, or only do a transaction backup once a day. None of these scenarios are good options. My question is, how is everyone else getting their large SQL Server database backups offsite. Are you just using tape, or have you found a offsite backup device that works well? Is anybody else using Barracuda to backup their SQL Server databases? If you do, then how do you have it setup?

  • Upgrading MySQL Connector/Net

    - by Todd Grover
    I am trying to publish a website with our hosting provider. I am getting error due to the fact that they only allow a medium trust and the MySQL Connector/Net that I am using requires reflection to work. Unfortunately, reflection is not allowed in a medium trust. After some research I found out that the newest version of the MySQL Connector/Net may solve this problem. Connector/Net 6.6 includes enhancements to partial trust support to allow hosting services to deploy applications without installing the Connector/Net library in the GAC. I am thinking that will solve my problem. So, I unistalled MySQL Connector/Net 6.4.4 and I installed MySQL Connector/Net 6.6.4. When I run the application in Visual Studio 2010 I get the error: ProviderIncompatibleException was unhandled by user code The message is An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct. InnerException is The provider did not return a ProviderManifestToken string. Everything works fine when I have Connector/Net 6.4.4 installed. I can access the database and perform Read/Write/Delete action against it. I have a reference to the following in the project: MySql.Data MySql.Data.Entity MySql.Web My connection string in Web.config <connectionStrings> <add name="AESSmartEntities" connectionString="server=ec2-xxx-xx-xxx-xx.compute-1.amazonaws.com; user=root; database=nunya; port=3306; password=xxxxxxx;" providerName="MySql.Data.MySqlClient" /> </connectionStrings> What might I be doing wrong? Do I need any additional setting(s) to work with version 6.6.4 that wasn't required in the older version 6.4.4?

  • Invoking SQL Loader with a DSN

    - by Zack
    I'm trying to load some data to an Oracle database using SQL Loader. Is it possible to invoke it with specifying the server to load the data into using a DSN instead of a TNS? Right now my command line looks like this: sqlldr uesr/password@tns_id..., I'd like to replace tns_id with a DSN that points to tns_id. Can SQL Loader figure out the TNS from the DSN by itself?

  • Excel UDF calculation should return 'original' value

    - by LeChe
    Hi all, I've been struggling with a VBA problem for a while now and I'll try to explain it as thoroughly as possible. I have created a VSTO plugin with my own RTD implementation that I am calling from my Excel sheets. To avoid having to use the full-fledged RTD syntax in the cells, I have created a UDF that hides that API from the sheet. The RTD server I created can be enabled and disabled through a button in a custom Ribbon component. The behavior I want to achieve is as follows: If the server is disabled and a reference to my function is entered in a cell, I want the cell to display Disabled If the server is disabled, but the function had been entered in a cell when it was enabled (and the cell thus displays a value), I want the cell to keep displaying that value If the server is enabled, I want the cell to display Loading Sounds easy enough. Here is an example of the - non functional - code: Public Function RetrieveData(id as Long) Dim result as String // This returns either 'Disabled' or 'Loading' result = Application.Worksheet.Function.RTD("SERVERNAME", "", id) RetrieveData = result If(result = "Disabled") Then // Obviously, this recurses (and fails), so that's not an option If(Not IsEmpty(Application.Caller.Value2)) Then // So does this RetrieveData = Application.Caller.Value2 End If End If End Function The function will be called in thousands of cells, so storing the 'original' values in another data structure would be a major overhead and I would like to avoid it. Also, the RTD server does not know the values, since it also does not keep a history of it, more or less for the same reason. I was thinking that there might be some way to exit the function which would force it to not change the displayed value, but so far I have been unable to find anything like that. Any ideas on how to solve this are greatly appreciated! Thanks, Che EDIT: By popular demand, some additional info on why I want to do all this: As I said, the function will be called in thousands of cells and the RTD server needs to retrieve quite a bit of information. This can be quite hard on both network and CPU. To allow the user to decide for himself whether he wants this load on his machine, he or she can disable the updates from the server. In that case, he or she should still be able to calculate the sheets with the values currently in the fields, yet no updates are pushed into them. Once new data is required, the server can be enabled and the fields will be updated. Again, since we are talking about quite a bit of data here, I would rather not store it somewhere in the sheet. Plus, the data should be usable even if the workbook is closed and loaded again.

  • Machine learning - training step

    - by palau1
    When you're using Haar-like features for your training data for an Adaboost algorithm, how do you build your data sets? Do you literally have to find thousands of positive and negative samples? There must be a more efficient way of doing this... I'm trying to analyze images in matlab (not faces) and am relatively new to image processing.

  • wamp server not working? or bad php code

  • Is there a simple way to make lists behave as files (with ftplib)

    - by Brent.Longborough
    I'd like to use ftplib to upload program-generated data as lists. The nearest method I can see for doing this is ftp.storlines, but this requires a file object with a readlines() method. Obviously I could create a file, but this seems like overkill as the data isn't persistent. Is there anything that could do this?: session = ftp.new(...) upload = convertListToFileObject(mylist) session.storlines("STOR SOMETHING",upload) session.quit

The user also needs to be able to remove the data from the document. So far, I've managed to remove the document property and variable, but I'm not sure how I would go about removing the field (that's already inserted into the document). Please advise. Yours sincerely, Kevin
