Does Oracle DB have the utility to compute the CRC?

Hi Pros,
CRC stands for Cyclic redundancy check as we all know, there are ways of caculate it using programing language like Java, C#,etc, since we are undertake the ETL job for data warehouse, there are many update operation in DB using SQL, so I am wondering if there any utility or package in DB to caculate the CRC, then we can attach it at the end of each record in table.
thanks & regards

Hi Hemant

  • Does Apple Canada have the worst customer support ever?

    Yes! Ask me why...
    I'm posting here a) to warn other Mac users what to expect if you ever need customer support and b) because there's no where you can actually e-mail comments to Apple, and trying to contact customer support has been fruitless (see below).
    Here's what happened to me...
    I bought my iBook just under three years ago - a few weeks ago, the logic board went. Now, because I purchased the computer less than three years ago, that's covered under the extended warranty for iBook logic boards (see here: http://www.apple.com/support/ibook/faq/).
    Simple, right? Well, I took my computer in to my local authorized service provider about three weeks ago. They confirmed the logic board was the problem... copied my receipt for the iBook to prove date of purchase... agreed that it was covered by the warranty.
    However, when they sent all this to Apple, their reply was that it was NOT covered because it was manufactured more than three years ago (although Apple's own website says it's purchase date - not manufacture date - that's important).
    I called Apple last Monday to find out what was going on. Spoke to a nice fellow named Kevin who said he'd look into it, and call me back the next day.
    Next day passed... no call. I called Kevin back left a message, and indicated I'd like to know what was going on.
    Wednesday passed... no call. By this point, I'm getting anxious - the service provider can't move ahead without authoriztion from Apple, Apple's not returning my calls (or the service provider's) to grant authorization.
    I tried Kevin again on Thursday. Left another message. No reply.
    Tried back on Friday morning. Left another message. Still no reply.
    Called customer support again Friday night. Antoine puts me hold for a half hour. I call back, explain that I've been on hold for half an hour, ask how long the wait should be. Antoine says two or three minutes. He puts me on hold again.
    For another ten minutes.
    I call back. Antoine explains that the reason I'm on hold is probably because customer service is closed. So why was I on hold for nearly an hour listening to terrible music? That's one of the mysteries of Apple customer support...
    So here I am, with a computer that's been in the shop nearly three weeks, that can't be repaired because Apple won't honour its warranty, and no way to even find out what's going on, because Apple's customer service is such an unnavigable maze.
    The sad thing is, I usually like Apples. I was even going to buy a new one this summer.
    Now - not a chance.
    The moral of the story? If you own an Apple, pray nothing ever goes wrong with it. If you expect your computer to ever need repairs, I'd suggest getting rid of your Apple now.
    If you're considering buying an Apple - consider again.
    As for me - from now on, make mine Microsoft.

    Does Apple Canada have the worst customer support ever?
    I doubt it.
    Seriously, would you like some help?
    Call back, and don't mess around with Customer Service. Immediately ask for Customer Relations. These are the people whose job it is to make an unhappy customer happy again. They aim to please.
    A polite, but seriously disappointed tone of voice is what you need, so take some deep breaths until you can achieve that.
    There was an article in the February, 2005, issue of Reader's Digest called "How to Complain." Please read these tips. Then call and tell Customer Relations your sad experience with Customer Service.
    How to Complain
    You call customer service to complain about a product, and you hang up angrier than when you started. That’s customer rage, a feeling experienced by millions of people with a major complaint, says Scott Broetzmann, president of an American firm that tells companies how to offer the best customer service. His secrets to getting good service:
    Have a goal
    If you want your product repaired, say so. Want an apology? Speak up.
    Keep it short
    Focus on one problem, and be succinct.
    Stick with it.
    You have to invest the time it takes. Don’t get what you want? Ask for a supervisor.
    Skip ultimatums
    Don’t threaten not to do business with them again. Why should they help you if you won’t buy from them in the future?
    Plead your case
    Many companies have information such as how much money you’ve spent with them and how often you complain. If you’re a good customer, they may be more willing to help.
    Be nice
    You’re unlikely to get what you want if you’re rude.
    Good luck!
    (P.S. Microsoft doesn't make computers; just the crappy OS that goes on them.)

  • When i plug in the recharger, mofst of the time my ipad says not chrging. Does anyone else have the problem?

    Most of the time my charger does not work . IPAD indicates not charging when recgarger plugged in. Does antone else have the problem?

    If you continue to have the issue with a different charger and if you are having any issues syncing with your computer then you may want to take it into an apple store and have them look at it.
    The main reason I say this, I had the 30 pin dock die on my iPad, and the symptoms were that it would not charge when plugged into the wall - and with multiple chargers - and it would not sync.
    So keep an eye on it, especially if you are close to the end of your warranty.

    The role for a coherence node is normally determined by the application. The tangosol.coherence.role system property is used to configure this value. Some out-of-the-box Coherence applications. CacheFactory (com.tangosol.net.CacheFactory) sets this value to CoherenceConsole. DefaultCacheServer sets this value to CoherenceServer. MBeanConnector sets the value to TangosolNetMBeanConnector.

    Does oracle a have tool like primavera or MS Project

    If you are looking for project scheduling the Project Program Management application from the PeopleSoft Enterprise product line can help you to schedule and track your project.
    There are also built-in project scheduling capability in the EnterpriseOne ETO product.
    The project scheduling capability in embedded in the enterprise apps. As far as I know, I have not seen a standalone, desktop based project scheduling tool from Oracle.

  • HT5446 if i order a new imac with 1tb flash is that pcie based to where i could add a 3.5 ssd and does it still have the bracket and sata cable to add one in it

    if i order a new imac with 1tb flash is that pcie based to where i could add a 3.5 ssd and does it still have the bracket and sata cable to add one in it

    Be advices that the newest iMac's are basically SEALED Units and taking it apart in any way, other than removing the Memory slot cover to add more RAM (That is on the 27" model. The 21.5" is completely sealed), will void the warranty on it.
    Not only that but the screen is Glued to the aluminum casing and if you do pry it off with damaging it you'll need new adhesive strips to remount it.
    Not worth the efford or the cost when you can buy mat any other brand computer for less money and do all the upgrading you would ever want without ever voiding the warranty or breaking something in the process.

  • After the newest update, i can no longer type in traditional chinese ( pin yin), does anyone else have the same problem?

    after the newest update ( iso 7) , i can no longer type in traditional chinese ( pin yin), does anyone else have the same problem?

    I downloaded and tried EasyFind. It works but it took 30+ seconds to complete finding 3 files that are on One of my Five 25+ Gb partitions of my 130 Gb Seagate Cuda(Really 160 Gb, but my Sawtooth will only recognize 130) I figured that if I ever got a better box, I could reformat it to see the whole 160 Gb. So, as far as I can see, Spotlight's indexing scheme which finds the files instantly is probably preferable. Spot light allows you to rename your files from within it's app window. I've always thought that was pretty powerful. Could my doing so be causing me any issues? As i said it is the inability to Type in the Finder that seemed to be caused from changing file Extentions that were mis-written. Maybe it was a delayed reaction to my renaming files in the Spotlight app? I've done both on occasion.
    As for these .DS_Store files. Apparently you can NOT stop them from being written to any folder that you touch/open/view during a days session. But, as a function of the OS, are the essential to have in their respective folders Forever? I've looked at the .DS_Store terminator app briefly and assume that getting rid of these files won't hurt the regular operation of my OS. They will just be re-written if I ever have to go back to any particular folder again. But, apparently, some have said that if the plan on burning a CD or DVD of their data, they delete the .DS_Store files first and then do the burn.
    I'm thinking from your having suggested this tremination app that you suspect that my having all of these ,DS_Store files could be a situation where any of them could have become corrupted and terminating them regularly should be part of my regular maintenance.
    Does that sound like I'm understanding what I can do?
    TIA

  • Does Captivate 7 have the capability to do dual audio recordings?

    Does Captivate 7 have the capability to do dual audio recordings?
    Do the setting of the recording devices affect its ability to do so?
    I am working on an HP  EliteBook 8560W.

    When you say "dual recordings", do you mean two audio sources (say audio playing from the laptop and narrator recording the audio)? If yes, then it is possible. You have to select the System Audio check box and the source of your narration audio before you start the recording.
    If not, please mention your audio sources and also type of recording you want do.

    No, the silent background update does not need a restart to complete the installation.
    However, it may need to wait until the browser is restarted in order to delete old files.  Nothing to worry about.

  • Does elements 10 have the perspective function in crop

    Hi I have a client who is an artist and she needs some image editing software but does not have the funds for photoshop.  She can purchase elements 10 quite cheaply but the most handy tool for her will be the perspective function in crop but I am not sure whether it is a feature of elements 10.  Thanks

    Once again, thanks Ken !
    I'll keep it, even though I have DxO which can give optimal results.
    That said, the filter 'Correct lens distortion' (already present in PSE6) is simple and efficient, plus it includes a zoom level to crop (bottom slider).
    Better than the 'Transform / perspective' adjustment I am used to.
