  • How effecient is a details table?

    - by Jeffrey Lott
    At my job, we have pseudo-standard of creating one table to hold the "standard" information for an entity, and a second table, named like 'TableNameDetails', which holds optional data elements. On average, for every row in the main table will have about 8-10 detail rows in it. My question is: What kind of performance impacts does this have over adding these details as additional nullable columns on the main table?

  • read and write permission for FAT32 partition in Ubuntu

    - by Dean
    This is a strange problem. I have the following partition table Device Boot Start End Blocks Id System /dev/sda1 * 1 13 102400 7 HPFS/NTFS Partition 1 does not end on cylinder boundary. /dev/sda2 13 5737 45978624 7 HPFS/NTFS /dev/sda3 5738 10600 39062047+ 83 Linux /dev/sda4 10601 19457 71143852+ 5 Extended /dev/sda5 10601 11208 4883728+ 82 Linux swap / Solaris /dev/sda6 11209 15033 30720000 b W95 FAT32 /dev/sda7 15033 19457 35537920 7 HPFS/NTFS I dual boot Win7 (sda2) and Ubuntu (sda3) and wanted to use the FAT23 partition to share files across two OS's. I followed some online tutorial and have done these: sudo mkdir /media/FAT32 sudo chmod 777 /media/FAT32 sudo mount /dev/sda6/ /media/FAT32 after I mounted the file, I can only read but not be able to write to it. I checked the file permission, it becomes: drwxr-xr-x but after I unmounted the it then becomes drwxrwxrwx and I can read and write to it. very strange. I don't know where I've down wrong. Cheers.

  • What is the data transfer speeds within the disk, to other devices?

    - by Kumar
    I use Debian 6 on a HP Elitbook 6930 with 2Gigs of RAM. I was copying two AVI files, 1.5 GB in total, and noticed that the data copying was done at the rate of 4MB/sec. When I copy same AVIs to my Western Digital Passport 25G USB plugin drive the data transfer speed is 11+MB/sec. This speed is different if I plugin the drive to different USB ports. Interestingly, at work I also downloaded a 16MB IE8 exe on my virtual xp, run inside Oracle Sun Virtual Box, and it was downloaded AND saved within a second. We have a high speed network at work. :-) Why and how this difference in data speeds is possible?

  • Recovering with DDRescue Cannot Complete (write error: Read-only file system)

    - by c00lryguy
    I'm trying to recover a corrupt VDI using vdfuse to mount the VDI and using dd_rescue to rescue the borked partition. dd_rescue seems to be working fine but once it reached about half of the partition, it just STOPs and gives the following error: ddrescue: write error: Read-only file system Wait.. what? It suddenly turns the FS it is writing the recovered partition to into a read-only file system. Well... why? Will I never be able to finish this? What's going on?

  • Configure ASP.NET Application to Read Mapped Network Drive

    - by Bob
    Is it possible to configure an ASP.NET application under IIS 7 so it can read files stored in a mapped network drive? I'm not trying to serve up the contents of the drive. I simply need to read the contents within the ASP.NET application. I've searched the Web and haven't really found a solid answer. The questions in my mind are: Is this possible via configuration (i.e. I cannot modify the client code)? If so, what are the step by step instructions. If it is not possible, I'm fine with that. I already know UNC paths work but using them drastically changes the work flow. Thanks! Bobby

  • Batch file reads in text file and replaces quotes with variables into new file?

    - by John
    I have customer Pizza lists that i have saved into 5 seperate txt files from my database in this format: Filename = 25Percent.TXT "555-1211" "555-1212" "555-1223" ... ect Each list is a phone number in quotes and each list varies in length. Part 1: I have two sets of variables that i would like to replace with each quote in the 5 text files. The two variables would be like: Var A = < Discount Pizza price for phone number is " Var B = " 25 % So i would like to run a batch file that reads each line in the text file and writes into another text file the following, replacing the quotes with the variables: New Filename = 25Percentfinished.TXT < Discount Pizza price for phone number is "555-1211" 25 % < Discount Pizza price for phone number is "555-1212" 25 % < Discount Pizza price for phone number is "555-1223" 25 % Then I would repeat for 30percent.txt, then 35percent.txt, 40percent.txt, and then finally 50percent.txt file. Part II: I would also like to append the 5 new files together, with the append command? I am assuming that the SET Var command would also be used? Not sure what to do here.

  • Exchange read receipt are delivered to recipient instead of sender

    - by Exchange33
    We have two interconnected Exchange organizations: Exchange 2003 and Exchange 2013. When users ask for read receipt in Outlook these receipts are delivered correctly within each organization. However when Exchange 2003 users send messages to Exchange 2013 users the read receipts are delivered to the Exchange 2013 recipients and instead of the message senders. We analyzed the message content at the recipient side and it looks like the message arrives with an incorrect ReadReceiptEntryID field. The field must contain the sender's address but it contains the recipient address instead. What can be the cause of the issue?

  • Windows XP - removing write protection for usb drives

    - by Arnold
    I have a laptop who used to belong to my company and when I plug in a usb memory drive, I cannot write any files to it. This is because company policy did not allow writing to usb drives without a special authorization (to prevent theft of files). However the laptop is now mine, and I was given the administrator password, so I am guessing that as administrator I can remove this protection somehow. How can I do this? Currently if I try to copy a file to the drive, Windows simply tells me that the drive is write-protected, whatever usb drive I plug in. Maybe it is some registry setting? Thank you.

  • Simultaneous read/write to RAID array slows server to a crawl

    - by Jeff Leyser
    Fairly beefy NFS/SMB server (32GB RAM, 2 Xeon quad cores) with LSI MegaRAID 8888ELP controlling 12 drives configured into 3 different arrays. 5 2TB drives are grouped into a RAID 6 array. As expected, write performance to the array is slow. However, sustained, simultaneous read/write to the array (wether through NFS or done locally) seems to practically block any other access to anything else on the controller. For example, if I do: cp /home/joe/BigFile /home/joe/BigFileCopy where BigFile is 20G, then even a simple ls /home/jane will take many 10s of seconds to complete. In addition, an ls /backup will also take many tens of seconds, even though /backup is a different array on the same controller. As soon as the cp is done, everything is back to normal. cp /home/joe/BigFile /backup/BigFile does not exhibit this behavior. It's only when doing read/write to the same array.

  • How to calculate unweighted averages in Excel PivotTable?

    - by yonatron
    I often make PivotTables in which each row contains a number of per-person average measures. I then want to look at the unweighted column average for each measure, and usually make some kind of chart from these. Because my individual cells are often averaged from different numbers of data points, the Grand Total row ends up being a weighted average, which I’m not interested in. So I usually make my own average row a few rows above the table to use for my charts. That’s not too much work, but there’s another problem. I often add a few more people’s worth of data to the PivotTables’ source, then refresh the tables. This means my average row needs to be updated to encompass more rows from the PivotTable. Not a huge deal with one table, but when I have lots of them across lots of sheets, I have to do find/replace on a whole bunch of formulas. So: is there a way to automatically get unweighted column averages in a PivotTable, such that when the table is refreshed, the averages don’t change locations and encompass the newly added (or removed) data Thanks

  • fstab line for auto mount drive that all users can read/write

    - by evilblender
    I have installed a cable that connects from the CPU's SATA motherboard connection to a removable drives' ESATA connection. I would like to be able to swap drives on the ESATA connection and have all users be able to read and write to these drives. I have created the directory /archive/ where I would like the drive(s) to mount. The drives are all formatted Fat 32 - but in the future I may use HFS for formatting. When I used the command (as root): mount /dev/sdc1 /archive the drive was mounted (but read only) What can I use in my /etc/fstab file that will allow drives to be mounted and unmounted by all users on the system? (both reading and writing) Also, will I be able to mount and unmount these drives without shutting down? or will I need to reboot every time I want to change drives? Thank you. Jeff

    I compiled OpenSSH_6.6p1 on one of our server. I am able login via SSH to the upgraded server. But I am not able to connect to other servers running OpenSSH_6.6p1 or OpenSSH_5.8 from this. While connecting I am getting an error as below. Read from socket failed: Connection reset by peer On the destination server in the logs, I am seeing it as below. sshd: fatal: Read from socket failed: Connection reset by peer [preauth] I tried specifying the cipher_spec [ ssh -c aes128-ctr destination-server ] as mentioned in here and was able to connect. How can configure ssh to use the cipher by default? Why is the cipher required here?

  • VMWare Workstation can't read CD/DVD drive

    - by Chris W
    A fresh install of VMWare Workstation 7 (7.1.1 build 282343) on Windows 7 64 bit. When I try to read a CD/DVD from a guest (either to install a fresh guest or to read a CD within an existing VM I get the following error: Cannot connect virtual device ide1:0 because no corresponding device is available on the host. I've tried fiddling with the IDE channels as well as tried SCSI with no joy. What am I missing? I can run ISOs fine but I don't want to have to convert everything to an ISO when I presume that this should just work fine.

  • Brand new Seagate HDD has high raw read error rate

    - by kpax
    I've just purchased a brand new Seagate ST31000524AS 1TB HDD. Manufacture date shows as January 2012 (yes that's as new as new can get), so must be one of the new batches from the post-flood Thailand. Anyway, I downloaded a copy of Active Hard Disk Monitor tool to check the S.M.A.R.T. parameters and I find the parameter Raw Read Error Rate is very low. Should I be worried? Will this rectify over time? This hdd is just 7 hours old; what gives? Edit: I meant high raw read error rate - Title updated accordingly

  • OSX Mail.app send only plaintext but read as html

    - by bawkstoo
    I get email which seems properly plaintext formatted, but when I forward it out, the font size ends up being enormous and a few other formatting stupidities. So I tried the following: defaults write com.apple.mail PreferPlainText -bool TRUE And this works great, all outgoing email regardless of the text original is plaintext only, just the way I like it. But now for incoming email only the plaintext portions are available to read without going into View - Message - Raw Source (or something similar to that). Does anyone know how I can force only outgoing mail to include only plaintext, but continue to read incoming mail in the formatting it was intended?

  • Sudden slow read & write speed on all IO

    - by user23392
    I have a custom built rig that has 2 storage drives. for OS: Western Digital 1.0TB HARD DR 64MB for other stuff: Corsair Performance 3 128GB (SSD) [ expected read speed: 400 mb/s ] The system was incredibly fast for a couple of months, then one day i was playing a game then it started to get buggy (some sounds and objects disappearing), i stopped the game and the system seemed to be unstable so i had to shut it down, next morning i couldn't start it up, it was saying something about corrupt device. I formatted both disks and installed a fresh copy of windows, all i can say that since that day the system was never like before, it takes 10 minutes to boot up (the icons and desktop slowly appear). but once it's done the slowness isn't as noticeable. Here's my benchmark on the HDD ( read speed - write speed ): And the SSD: Anyone knows what could be the issue?

  • HFS partition mounting read-only

    - by Sid
    Hey, I have an external Western Digital Hard drive with two HFS partitions with journaling disabled. When I connect it to a computer running Linux (Debian or Ubuntu), frequently both partitions are mounted read-only. In the past, mounting them on my Macbook and executing the command to disable the journaling often worked (even though it would tell me that journaling was already disabled) but I would love to have a solution which works every time. Thanks! Edit: In light of Chris Johnsen's comment below - my question is how to mount the filesystem read+write on Linux since it is not automatically doing so itself

  • Linux Read-Ahead Downsides

    - by JPerkSter
    Hi Everyone, Hope all is well. I have a question regarding read-ahead caching. Are there any downsides to raising the size of the read-ahead cache? On our farm, we're currently running at 256, and upon raising that higher, we are seeing significant throughput gains.   [root@server~]# hdparm -tT /dev/sda /dev/sda: Timing cached reads: 7352 MB in 2.00 seconds = 3677.62 MB/sec 3 Timing buffered disk reads: 244 MB in 3.10 seconds = 78.68 MB/sec [root@server ~]# blockdev --setra 10240 /dev/sda [root@server ~]# hdparm -tT /dev/sda /dev/sda: Timing cached reads: 11452 MB in 2.00 seconds = 5728.52 MB/sec Timing buffered disk reads: 422 MB in 3.17 seconds = 133.04 MB/sec We are running on 2.6. Thanks!
