Whats the diffrence between these two JKM's and when to use which one.

Please tell the diffrence between these two.
JKM Oracle Consistent o JKM Oracle Consistent (Update Date)

Basic difference is in the requirement .
JKM Oracle Consistent (Update Date) wants a DATE/TIMESTAMP column in the source tables(s) which will get inserted/update by the source application . ODI will capture the changed data based on this column value . Only the DELETE portion requires a trigger to keep track of deletion happening at source table(s).
Where as JKM Oracle Consistent does not require any DATE/TIMESTAMP column in the source tables(s) . It uses triggers for keeping track of INSERT/UPDATE/DELETE happening in source .
In terms of performance JKM Oracle Consistent (Update Date) is better as it will create littel over head on to your source system . SO if you have a DATE/TIMESTAMP column in the source tables(s) which gets inserted/update by the source application, then go for JKM Oracle Consistent (Update Date) .
Else look for JKM Oracle Consistent .
Thanks,

    My feeling here is that simply changing join syntax and case vs decode issues is not going to give any significant improvement in performance, and as Tubby points out, there is not a lot to go on. I think you are going to have to investigate things along the line of parallel query and index vs full table scans as well any number of performance tuning methods before you will see any significant gains. I would start with the Performance Manual as a start and then follow that up with the hard yards of query plans and stats.
    Alternatively, you could just set the gofast parameter to TRUE and everything will be all right.

  • Whats the difference between these two Sony's

    so ivwe narrowed my next laptop to.....the Sony  VPCCW21FX  and  VPCCW23fx.  My question is, after looking at the specs of both it seems the only difference s that one (21) has a blu ray and the other doesnt.  Is that the only difference?well besides one being cheaper? 
    thanKs!
    Scott

    Yeah besides the color options, the addition of the Blu-ray drive is the only thing going to seperate these 2 laptops.

  • What is the difference between these two portalapps folders on the Server?

    Hello,

    1. Under: C:\usr\sap\JXX\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\portalapps
    2. Under: C:\usr\sap\JXX\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\portal\portalapps
    Can someone please explain me what is the difference between these two portalapps folders and under which case will I turn to which folder?

    Hi Roy,
    The one at this location
    Under: C:\usr\sap\JXX\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\portalapps
    has all the files from the WEB-INF folder i.e. these are the non-web resources and cannot be accessed via HTTP(S) examples would be imgaes, CSS etc that you want only your application to access
    those under
    Under: C:\usr\sap\JXX\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\portal\portalapps
    they have all the .JAR files, portalapp.xml, config properties etc. these are web resources and can be accessed via HTTP(S)

  • Whats the difference between these versions of photoshop?

    First of all to make things clear I want to mention this first that I lives in Pakistan and Adobe doesn't support my region so in order to buy the Adobe Photoshop CC I have to contact the authorized resellers, after contacting them and asking for a invoice proposal for Adobe Photoshop CC, they send me several invoice proposals (per user team liscense). But I just got in a trouble as these proposals are offering Photoshop CC different versions so its like kinda making me double mind, i am just confused which to buy as prices are differ too and kinda noticeable. As for making my intentions clear I also wanna mention that I am looking for Single App Liscense i mean i just wanna buy Photoshop CC thats it. But for sure its not gonna be that photography version nor student one. Also i wanna know that whats the difference between these two versions and also tell me the pros and cons.
    So please help me choose which one is better for me as I am really confused with it.
    Here are the links
    Note: You will have to translate these pages into english
    Link one:
    [65224660BA01A12] ราคาพิเศษ จำหน่าย Photoshop CC ALL Multiple Platforms Multi Asian Languages Licensing Subscription Mo…
    Link two:
    [65226001BA01A12] ราคาพิเศษ จำหน่าย Photoshop CC ALL Multiple Platforms Multi Asian Languages Licensing Subscription Mo…
    I've attached screenshots too

    The features in both of the Photoshop CC are identical, there is a difference in price because, the higher priced is the original Photoshop price, the less priced is the promotional priced Photoshop CC eligible only if you have CS3 or later version of Adobe creative suite product.
    Hope this answers your question.
    Regards

  • What is the difference between these two sticks of RAM?

    I am upgrading my Macbook 2.2 GHz Intel Core 2 duo from 2GB of ram to 4GB
    What is the difference between these two kits?
    4GB Kit (2 x 2GB) 200 Pin DDR2-667 PC2-5300 256x64 CL5 1.8V SODIMM ($102.00)
    4GB Kit (2 x 2GB) eRam 200 Pin DDR2-667 PC2-5300 CL5 1.8V SODIMM ($88.00)

    Probably nothing of any consequence. Some places can just negotiate better deals with suppliers. Or one of a million other factors that can affect price is in play here.
    When buying RAM, I generally find it's better to pay a little extra to get a brand that's known for quality. I usually stick to Crucial myself. If you look around, you can probably find some real steals out there, but I don't know... With stories of people who literally go dumpster diving, salvaging stuff that was slated for disposal, then turning around and selling it... I prefer not to take chances. If you are, by all means, go for the cheaper one.

  • What is the Difference between these Two?

    Hi All,
    In Oracle University site i saw 2 Courses for Oracle Webcenter sites. Just i would like to know the difference between these two. Based on your input i can decide which one to take.

    Is the 1st one is Fatwire and the 2nd one is Fatwire+Oracle latest implmentation ? Is my understanding is right?

    It's the same lens, just different sellers.  The higher one is the MSRP, or close to it.  But since they use this lens in a kit it goes for less.  I have no idea who Celltime Inc is, but it's fullfilled by Amazon, so I'd feel reasonably safe.  Just look into their return policy.
    With the recent release of the 6D and somewhat recent 5d3, the market is flooded with these lenses from kits; I wouldn't pay more than 800 something for it.  Getting it through Amazon is a bonus over eBay.  If the seller checks out I'd go for it.
    Edit: DH beat me to it. 

  • What's the difference between these two networks?

    Have searched a lot but can not find a clear answer to the difference between these two networks.
    (I'm using these as examples only)
    Using Airport utility
    * sometimes theres a dotted line "......"
    *And sometimes there's a solid line like a " } "
    I chose these as an example because ours is just like the first example above.
    However sometimes our presents similar to the above example only with two devices, not three.

    Dotted line is wireless.. Solid line is ethernet..
    Normally all ethernet should show as your lower picture since all are directly wired..
    Wireless should show which Airport is the main base and which extend using wireless.
    But it is 50% science and 80% voodoo (voodoo cannot count even!!)

    Hi gundozer
    It is just software related. An analogy is Sony Ericsson K750i of which early versions could be converted into W800i Walkman with different software.
