• DataSet.GetChanges - Save the updated record in a different table than the source one

  - by John Dev

  I'm doing operation on a dataset containing data from a sql table named Test_1 and then get the updated records using the DataSet.GetChanges(DataRowState.Modified) function. Then i try to save the dataset containing the updated records on a different table than the source one (the table is names Test and has the same structure as Test_1) using the following statement: sqlDataAdapter.Update(changesDataSet,"Test"); I'm getting the following error : Update unable to find TableMapping['Test'] or DataTable 'Test' I'm new to ado.net and don't even know if it"s something possible. Any advice is welcome. Just to provide a bit of context. ETL jobs are importing data in temp table with same structure as the original but with _jobid suffix. Right after a rule engine is doing validation before updating the original table.

• ERROR: there is no parameter $1 when creating view

  - by idlemoments

  When we try to create a view within a funcion we get ERROR: there is no parameter $1. This is the sample code. Begin CREATE VIEW artikelnr AS SELECT datum, 'uitgifte' as "type", CASE WHEN 'test'='test' THEN 0 END as "aantal ontvangen", aantal as "aantal uitgegeven" FROM uitgifteregel JOIN artikel ON artikel.artikelnr = new.artikelnr JOIN uitgifte ON uitgifte.uitgiftenr = uitgifteregel.uitgiftenr UNION SELECT datum, 'ontvangst' as "type", aantal as "aantal ontvangen" , CASE WHEN 'test'='test' THEN 0 END as "aantal uitgegeven" FROM ontvangstregel JOIN artikel ON artikel.artikelnr = new.artikelnr JOIN ontvangst ON ontvangst.ontvangstnr = ontvangstregel.ontvangstnr; Return new; end; When we replace new.artikelnr on line 7 with value 1 it works like it should, but the function needs to work with different artikelnr's. example line 7: JOIN artikel ON artikel.artikelnr = new.artikelnr Please point us in the right direction.

• "if" expression question

  - by Here

  Hi, I test some simple F# code for "if" expression, but the result is unexpected for me: > let test c a b = if c then a else b;; val test : bool -> 'a -> 'a -> 'a However > test true (printfn "a") (printfn "b");; a b val it : unit = () I'd expect only "a" is printed out but here I got both "a" and "b". I wonder why it comes out this way? Thanks!

• Quiz module as a part of SQL Tutorial (Project) in C#. Help!

  - by N1107

  Kindly help. Am a beginner in C#. The details of my project work include: Front End: C# Back End: SQL MS Visual Studio 2010 Windows Application Quiz Module Each session contains 20 questions. At the end of the test, the test-engine will evaluate the answers. If the student obtains more than 50% then he can unlock the next module. And his test score is printed using Crystal Reports and saved in teacher's database, against that student's record. Else, if his score is less than 50%, the test-engine will count the no. of attempts to clear the quiz & randomly generate another set of 20 questions from a file (from the teacher's database). It's complicated for me cause am a beginner. Would appreciate some help. Thanks.

I've checked the BIOS settings and the memory seem to be running at full speed. According to the hosting company the modules are all OK. Could this have something to do with NUMA?

• Courier Maildrop error user unknown. Command output: Invalid user specified

  - by cad

  Hello I have a problem with maildrop. I have read dozens of webs/howto/emails but couldnt solve it. My objective is moving automatically spam messages to a spam folder. My email server is working perfectly. It marks spam in subject and headers using spamassasin. My box has: Ubuntu 9.04 Web: Apache2 + Php5 + MySQL MTA: Postfix 2.5.5 + SpamAssasin + virtual users using mysql IMAP: Courier 0.61.2 + Courier AuthLib WebMail: SquirrelMail I have read that I could use Squirrelmail directly (not a good idea), procmail or maildrop. As I already have maildrop in the box (from courier) I have configured the server to use maildrop (added an entry in transport table for a virtual domain). I found this error in email: This is the mail system at host foo.net I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

• the font of xubuntu

• Why is syslog so much slower than file IO?

  - by ceving

  I wrote a simple test program to measure the performance of the syslog function. This are the results of my test system: (Debian 6.0.2 with Linux 2.6.32-5-amd64) Test Case Calls Payload Duration Thoughput [] [MB] [s] [MB/s] -------------------- ---------- ---------- ---------- ---------- syslog 200000 10.00 7.81 1.28 syslog %s 200000 10.00 9.94 1.01 write /dev/null 200000 10.00 0.03 343.93 printf %s 200000 10.00 0.13 76.29 The test program did 200000 system calls writing 50 Bytes of data during each call. Why is Syslog more than ten times slower than file IO? This is the program I used to perform the test: #include <fcntl.h> #include <stdio.h> #include <string.h> #include <sys/stat.h> #include <sys/time.h> #include <sys/types.h> #include <syslog.h> #include <unistd.h> const int iter = 200000; const char msg[] = "123456789 123456789 123456789 123456789 123456789"; struct timeval t0; struct timeval t1; void start () { gettimeofday (&t0, (void*)0); } void stop () { gettimeofday (&t1, (void*)0); } void report (char *action) { double dt = (double)t1.tv_sec - (double)t0.tv_sec + 1e-6 * ((double)t1.tv_usec - (double)t0.tv_usec); double mb = 1e-6 * sizeof (msg) * iter; if (action == NULL) printf ("Test Case Calls Payload Duration Thoughput \n" " [] [MB] [s] [MB/s] \n" "-------------------- ---------- ---------- ---------- ----------\n"); else { if (strlen (action) > 20) action[20] = 0; printf ("%-20s %-10d %-10.2f %-10.2f %-10.2f\n", action, iter, mb, dt, mb / dt); } } void test_syslog () { int i; openlog ("test_syslog", LOG_PID | LOG_NDELAY, LOG_LOCAL0); start (); for (i = 0; i < iter; i++) syslog (LOG_DEBUG, msg); stop (); closelog (); report ("syslog"); } void test_syslog_format () { int i; openlog ("test_syslog", LOG_PID | LOG_NDELAY, LOG_LOCAL0); start (); for (i = 0; i < iter; i++) syslog (LOG_DEBUG, "%s", msg); stop (); closelog (); report ("syslog %s"); } void test_write_devnull () { int i, fd; fd = open ("/dev/null", O_WRONLY); start (); for (i = 0; i < iter; i++) write (fd, msg, sizeof(msg)); stop (); close (fd); report ("write /dev/null"); } void test_printf () { int i; FILE *fp; fp = fopen ("/tmp/test_printf", "w"); start (); for (i = 0; i < iter; i++) fprintf (fp, "%s", msg); stop (); fclose (fp); report ("printf %s"); } int main (int argc, char **argv) { report (NULL); test_syslog (); test_syslog_format (); test_write_devnull (); test_printf (); }

• File server share access intermittent/slow/machine unstable: win2k8r2

  - by Jack B.

  I have a file server running Win2k8R2 on an older HP DL380G4. It has nothing set up on it other than file sharing. All drivers/firmware/updates installed. The file server is used as a dump for a bunch of test machines - so essentially a lot of small files are being written to it. It was working fine until it started showing the following symptoms: Shares became either very slow/intermittent or could not access them at all. Logging in the the server, you could use it like normal but windows would start freezing and eventually you had to hard reboot it because nothing was responsive. After rebooting, it would work fine for 20min-2hours and then degrade into this broken state again. Some info after investigation: HP Raid Config utility shows the Raid array as functioning properly (RAID5 btw). Event log shows a bunch of DoS attacks from the test machines, saying it has disconnected the connection a. AFAIK (not part of my job) the test machines haven't changed the way they log information to this server or the amount of them hasn't increased. b. Nothing is infected, this server was scanned fully, and the test machines are re-imaged almost daily. Nothing in performance monitor shows as anything being pegged at maximum (CPU/HD/Network/RAM) I installed MS Network Monitor and it is showing a lot of traffic The server was using one gigabit Ethernet connection, I connected the second one as well with the same results. Forgot to add - one of the commonly written to dirs on the share has over 16k subdirs in it, with a crapton of small files within those dirs. Some of the OS instability was slow access to the drive which has this directory - perfmon doesn't show much activity on the HD though so I'm not sure if this crowded dir is the cause. Here is one important fact: I ran into this issue 2-3 months ago, couldn't figure it out, but I had a spare identical machine so I swapped them out (thought it was related to the machine), and now I have the same issue. Also, the computer will be stable if I turn off file sharing. So is the server just getting DoS'd by the test machines? I've never dealt with such an issue. Is instability in the server's OS common when getting DoS'd? Is there anything I can do to confirm this before telling the owners of the test machines to optimize their traffic? (I'm not sure what they'll be able to do). Is there something within Win2k8R2 that can balance the traffic across the two NICs? Any help would be appreciated. Update: Another thought - the drive with the share is RAID5 across 6 SCSI320 300GB HDs. They are near full capacity about 100GB from 1TB left. Could the amount of tiny files could be causing some weirdness with the parity in this array? I think I've read something about this in the past but I'm no expert on RAID.

• Intel z77 vs h77 for intensive compiling, gaming [closed]

  - by Bilal Akhtar

  I'm in the market for a desktop motherboard (preferably ATX) that functions well with Intel i7-3770 Ivy Bridge processor at 3.4 GHz with LGA1155 socket. That processor is very fast, and it should handle all my tasks. My question is about the type of motherboard chipset I should choose to accompany it. I plan to use my rig for compiling and developing Debian package and other OS components, web development, occasional Android apps, chroots, VMs, FlightGear, other gaming but nothing serious, and heavy multitasking, all on Ubuntu. I do NOT plan to overclock, and I never will, so that's not a cause of concern for me. That said, I'm down to three chipset choices: Intel H77 Intel Z68 Intel Z77 I'm planning to go for H77 since I don't need any of the new features in Z77. I don't plan to use a second GPU and I will never overclock my CPU/GPU. My question is, will H77 based MoBos handle all my tasks well? Intel advertises that chipset as "everyday computing" but other sites say it's base functionality is the same as Z77. Intel rather advertises Z77 for "serious multitaskers, hardcore gamers and overclocking enthusiasts". But the problem with all Z77 motherboards I've seen is, they're way too expensive and their main feature seems to be overclocking, which won't be useful to me. Will I lose any raw CPU/GPU performance or HDD R/w with the H77 when comparing it to a Z77? Will heat, etc be an issue too? From what I've seen, Z77 motherboards have larger heat sinks when compared to H77 ones. Will that be an issue too, if I go with an H77 motherboard with no heat sinks for the chipset? The CPU will have a fan in both cases, of course. tl;dr When it comes to CPU/GPU performance and HDD r/w, is the Intel H77 chipset slower than the Z77? I don't care about overclocking or multiple GPUs, and for the processor, I'm set on Ivy Bridge i7-3770.

• EC2 Configuration

  - by user123683

  I am trying to create a server structure for my EC2 account. The design I have chosen consists of 2 instances running in different availability zones, elastic load balancer, an auto-scaling group with cloudwatch monitoring configured and a security group defining rules for access to the instances. This setup is to support an online web application written in PHP. I am trying to decide what is a better policy: Store MySQL DB on a separate Instance Store MySQL DB on an attached EBS volume (from what i know auto-scaling will not replicate the attached EBS volume but will generate new instances from a chosen AMI - is this view correct?) Regards the AMI I plan to use a basic Amazon linux 64 bit AMI, and install bastille (maybe OSSEC) but I am looking to also use an encrypted file system. Are there any issues using an encrypted file system and communication between the DB and webapp i neeed to be aware of? Are there any comms issues using the encrypted filesystem on the instance housing the webapp I was going to launch a second instance or attach a second volume in the second availability zone to act as a standby for the database - I'm just looking for some suggestions about how to get the two DB's to talk - will this be a big task Regards updates for security is it best to create a recent snapshot and just relaunch and allow Amazon to install updates on launch or is the yum update mechanism a suitable alternative - is it better practice to relaunch instead of updates being installed which force a restart. I plan to create two AMI snapshots one for the app server and one for the DB each with the same security measures in place - is this a reasonable - I just figure it is a better policy than having additional applications that are unnecessary included in a AMI that I intend on using. My plan for backup is to create periodic snapshots of the webapp and DB instances (if I use an additional EBS volume instead of separate instances my understanding is that the EBS volume will persist in S3 storage in the event of an unexpected termination and I can create snapshots of the volume backup purposes). Thanks in advance for suggestions and advice. I am new to EC2 and I may have described unnecessary overkill but I want to try implement what can be considered a best practice solution so all advice is appreciated.

• Network Load Balancing and AnyCast Routing

  - by user126917

  Hi All can anyone advise on problems with the following? I am planning on installing the following setup on my estate: I have 2 sites that both have a large amount of users. Goals are to keep things simple for the users and to have automatic failover above the database level. Our Database will exist at the primary site and be async mirrored to the secondary site with manual failover procedures.The database generate sequential ID's so distributing it is not an option. I plan to site IIS boxes at both sites with all of the business logic on them and heavy operations. The connections to SQL will be lightweight and DB reads will be cached on IIS. On this layer I plan to use Windows network load balancing and have the same IP or IPs across all IIS boxes at both sites. This way there will be automatic failover and no single point of failure. Also users can have one web address regardless of which site they are in automatically be network load balanced to their local IIS. This is great but obviously our two sites are on different subnets and as this will be one IP address with most of our traffic we can't go broadcasting everything across the link between the sites. To solve this problem we plan to use AnyCast routing over our network layer to route the traffic to the most local box that is listening which will be defined by the network load balancing. Has anyone used this setup before? Can anyone think of any issues with this? Also some specifics I can't find anywhere at the moment. If my Windows box is assigned an IP and listening on that IP but network load balancing is not accepting specific traffic then will AnyCast route away from that? Also can I AnyCast on a socket level?

• Debian, How to convert filesystem from ISO-8859-1 into UTF-8?

  - by Johan

  I have a old pc that is running Debian stable, that is in need of a upgrade. The problem is that it is using latin1 (ISO-8859-1) for everything, and since the rest of the world has moved to UTF-8 I plan to convert this computer as well. And for this question I will focus in on the files that are served with Samba, and some has some latin1 characters in the filenames (like åäö). Now my plan is to move all data of this old computer onto and a brand new one that is running Debian stable (but with UTF-8). Does anybody have a good idea? Thanks Johan Note: later I plan to use iconv to convert the content of some files with something like this: iconv --from-code=ISO-8859-1 --to-code=UTF-8 iso.txt > utf.txt However I don't know of a good way to convert the filesystem it self. Note: Normally I usaly just scp from one computer to the next, but then I end up with latin1 characters in the utf-8 filesystem... Update: Did a small test round with a hand full of files (with funny chars) in the filenames, and that seemed like it could work. convmv -r -f ISO-8859-1 -t UTF-8 * So it was only to execute with the --notest convmv -r -f ISO-8859-1 -t UTF-8 --notest * Nothing more to it.

• How to decouple development server from Internet?

  - by intoxicated.roamer

  I am working in a small set-up where there are 4 developers (might grow to 6 or 8 in cuople of years). I want to set-up an environment in which developers get an internet access but can not share any data from the company on internet. I have thought of the following plan: Set-up a centralized git server (Debian). The server will have an internet access. A developer will only have git account on that server, and won't have any other account on it. Do not give internet access to developer's individual machine (Windows XP/Windows 7). Run a virtual machine (any multi-user OS) on the centralized server (the same one on which git is hosted). Developer will have an account on this virtual machine. He/she can access internet via this virtual machine. Any data-movement between this virtual machine and underlying server, as well as any of the developer's machine, is prohibited. All developers require USB port on their local machine, so that they can burn their code into a microcontroller. This port will be made available only to associated software that dumps the code in a microcontroller (MPLAB in current case). All other softwares will be prohibited from accessing the port. As more developers get added, providing internet support for them will become difficult with this plan as it will slow down the virtual machine running on the server. Can anyone suggest an alternative ? Are there any obvious flaws in the above plan ? Some key details of the server are as below: 1) OS:Debian 2) RAM: 8GB 3) CPU: Intel Xeon E3-1220v2 4C/4T

• Is there anything like Heroku for PHP and/or .NET?

  - by Wayne M

  In my area PHP is very widespread, so is .NET. Ruby not so much; most places have never heard of it. For some personal things I am "forced" to choose Rails because I want to take advantage of Heroku - the ability to deploy and scale on the cloud very easily is the main reason. Also, they offer a small FREE plan, with no ads or strings attached, that I can use for demo sites or, in this case, for my business' static page; as a totally bootstrapped startup I have maybe $50 or so in initial capital and cannot afford to pay monthly fees while I'm getting started. Are there any similar offerings for other languages? Specifically, I really like the small, 5MB site for free that Heroku offers - is there anything like that for PHP and/or .NET? I'm not even that concerned about the "cloud" part, but that would be a nice bonus. If there is, I might be able to kill two birds with one stone and pick up a useful skill as I'm doing my own thing instead of using something that nobody else knows or cares about. I should add I'm specifically interested in something that offers a free plan. As I said, Heroku has a 5mb plan that you can have as many as you want for free; I have yet to find anything similar for any other platform (most of the "free" sites require you to have ugly banners on your page, or don't allow you to use your own domain name), and to be honest I'm not too thrilled about using Ruby on Rails for everything simply to take advantage of this. I'm asking this here because I already asked it on StackOverflow and someone suggested it would be better suited here.
