Difference between " COMPRESS FOR ALL OPERATIONS" and "COMPRESS FOR OLTP"?

I was looking through Oracle's OLTP Table Compression (11g onwards) documentation as well as online resources to find the syntax and came across two different versions:
COMPRESS FOR ALL OPERATIONS
and
COMPRESS FOR OLTP
The documentation I looked through didn't mention any alternative syntax, so i was wondering if anyone here might know the difference.
Thank you!

Table Compression Enhancements in Oracle Database 11G Rel1 as as follows:
The compression clause can be specified at the tablespace, table or partition level with the following options:
•NOCOMPRESS - The table or partition is not compressed. This is the default action when no compression clause is specified.
•COMPRESS - This option is considered suitable for data warehouse systems. Compression is enabled on the table or partition during direct-path inserts only.
•COMPRESS FOR DIRECT_LOAD OPERATIONS - This option has the same affect as the simple COMPRESS keyword.
•COMPRESS FOR ALL OPERATIONS - This option is considered suitable for OLTP systems. As the name implies, this option enables compression for all operations, including regular DML statements. This option requires the COMPATIBLE initialization parameter to be set to 11.1.0 or higher.

  • Difference between the TABs  "All Content" and "Discussions" on the new forum?

    Hi,
    Does anyone know the difference between the TABs  "All Content" and "Discussions" on the new forum?  They seem to be the same.  I'm confused.
    Petey

    Petey,
    Though I was part of the forum update beta, there was some that we could not effectively test, plus some aspects (like "Like"), that some liked, but others did not. That sort of thing happens.
    Also, now that we have the full version, and all servers are synced, there will probably be things that the beta testers did not get to experience. We will all be learning, in the process too. Also remember, much of the new forum software was provided by Jive, and though many of us commented (pros and cons), only so much could be addressed. It was not quite like doing a beta on Adobe software, as there was a complete, separate layer in between.
    So far, what I see looks close to what we saw a few weeks (months?) ago. Now, I need to really put the real software through its paces, to see what got changed from then, until now.
    Good luck,
    Hunt

  • Difference between Compression and Aggregation

    Hi,
      Can anybody explain the Difference between Compression and Aggregation.Performance wise which is better and explain me in detail.
      Thnaks,
      Chinna

    Hi,
    suppose you are having three charecteristics in a cube say X,Y,Z..
    Even for the records which are having the same combination of these charecteristics but are loaded with different request they won't get aggregated.
    So when you go for compression the records , it deletes the request number, and aggregates the records which are having the same combination of these records.
    Coming to the aggregates , if you build a aggregate on the charectaristic say 'X' then it aggregates the records which are having the same value for a particular charecteristic.
    ex: say you are having the recrds as
    x1, y1 ,z1......(some key figures)
    xi, y2,z1,.....
    x1,y1,z1,....
    x3,y3,z3...
    If you compress them, you will get three records.
    If you go for aggregates based on the charecteristic 'X' you will get two records.
    So aggregates will give more aggregate level of data than compression

    Oh ok, well that was what the test said prior to reformatting the hard drive. Now, it doesn't find any trouble no matter how many times I run it. That's what has me so confused, everything seems to check out and yet...I can't do anything, not even install the software!

  • Difference between cleared items,open items and all postings (FI).

    Hi experts,
    Can anybody tell me the difference between cleared items,open items and all postings for an account.
    While running corresponding bapis and transaction FAGLL03 (for GL) or FBL1N (for accounts payable) i found that in some cases all postings is less than cleared items or open items for a time period. How could it happen.According to my knowledge all postings should contain cleared items and open items.
    Please correct me..
    Thanks and Regards
    Arjun

    Hi Arjun,
    For every Billing Documnet created(VBRK/VBRP-VBELN) there will be an accounting document created in BSID/BSAD tables.
    OPEN ITEMS means the Billed/Invoice Amounts that are pending from Customers, i.e which we have to receive from Customers.
    CLOSED ITEMS means the AMOUNTS received from that customer.
    OPEN ITEMS : fetch data from BSID table Only
    CLOSED ITEMS : fetch data from BSAD only.
    ALL POSTINGS : fetch data from both BSID and BSAD.
    Hope this will help.
    Regards,
    Nitin.

  • What are the differences between Turn in Final Timesheet and the other option: Send Progress for Selected Tasks?

    Hello,
    The resource filled his/her timesheet in PWA. 
    Now : 
    What are the differences between Turn in Final Timesheet
    and the other option: Send Progress for Selected Tasks?
    Thanks

    You are partially correct and partially wrong.
    Turn
    in Final Timesheet sends
    the timesheet to the Timesheet Manager for Approval
    but task update always goes to Status manger of the task. Taks manager you can see in MPP(insert status manager field then check)
    Yes
    after approval progress will be available in MPP as well as in Projectweb app as % complete . 
    Send
    Progress for Selected Tasks 
    Send progress of selected task to status manager after approval update will be available in both MPP and Projectweb
    app as % complete.
    In Send
    Progress for Selected Tasks Timesheet
    Manager doesn't receive anything in his Approval center
    because all the update directly go to Status manager Approval center.
    Here you have to understand
    that there are two role Timesheet Manager(for timesheet approval) and Status manager(for task
    actual approval)

    I converted video into frames. There is a big difference between video size(700 MB) and All frames size(More than 5 GB). What are the reasons ?

    Please, are you sure that you posted this in the correct forum? This is the Adobe Captivate forum, not a forum for video created with other applications like Premiere Pro.

  • Difference between Reporting Services Sharepoint Mode and Reporting Services Add In for Sharepoint 2013

    Hi, We are building company site with Sharepoint 2013 Enterprise Edition and were wondering what is the difference between Reporting Services Sharepoint Mode and Reporting Services Add In for Sharepoint 2013? What are the roles/purposes of each one? What
    happens if only Reporting Services Sharepoint Mode  installed or vise versa.
    Thank you in advance

    Reporting Services in SharePoint mode is a service for displaying, managing, and creating SSRS reports within SharePoint. The addin is a pre-req for SharePoint that is used to display reports and is required for Reporting Services in Native or SharePoint
    mode, but does not by itself do anything.

  • Difference between batarries for Macbook air A1245 and A1237?

    Hello. Is there any difference between batarries for Macbook air A1245 and A1237(the very first air)? I often see ads in Internet where baterries are described like *for A1245/A1237*. Please, help.

    So, just to make it clear. What is a1245? I know that there is no such MBA, but why people mark batteries as *a1245/a1237*?
    If I buy battery marked *a1245/a1237*, will it work? See an example http://www.ebay.com/itm/Battery-for-Apple-MacBook-Air-13-A1245-A1237-MB003-MC233 -MC233LL-A-MC234-A1304-/300934966726

  • Difference between mastered for iTunes and previous versions?

    Is there a noticeable difference between Mastered for iTunes albums and any previous versions? I purchased Bon Jovi's "Have A Nice Day (Special Edition)", and now it has been replaced with a Mastered for iTunes version. Is there any value or noticeable difference if I were to purchase the new version?

    One of the inexpensive compilation downloads I purchased on iTunes was terrible, I'd much rather listen to the original mix of " I had too much to dream last night" than the remaster, which destroyed the song completely.
    Well, there is really no way to improve on the sound of The Electric Prunes coming over an AM transistor radio!
    I guess I'm suspicious of iTunes files in general. I am a dying breed, using separate amps and pre-amps and real speakers as well as Ultimate Ear earbuds and a great car system. The cuts that are engineered for iTunes are mixed for lo-fidelity appliances and just don't sound that good.
    There are online download stores that cater to a more audiophile crowd.  Check out HD Tracks.

  • Getting Big Headache, What is difference between Flash Lite 3.1 and Flash Player 7

    Hello, I am asking questions about the two similar yet different programs for Pocket PC version only:
    1) Which came first, Flash Lite 3.1 or Flash Player 7?
    2) If I have both in my Pocket PC, will there be product incompatibility?
    3) What is the difference between Flash Lite 3.1 and Flash Player 7.
    4) I have a Flash Lite 3.1 but uninstall information says "Flash Lite 3.1 for Opera Mobile", did you releaase this? Is this an illegal copy? A developer's copy?
    *I don't know exactly where I got it, but I got it from the HTC developer's forum: XDA-developers.com
    *I also use Opera mobile, a web browser for Pocket PC's.
    5) What is difference between Flash Lite 3.1 and Flash Lite 3.1 for Opera? Is the only difference is that Flash Lite Supports everything flash related, while Flash Lite Opera supports only flash in opera?
    Hi, I don't expect all answers, but I hope someone or someone from adobe support can clear some things up for me.

    The program under my "remove programs" list is specifically called "Adobe Flash Lite for Opera". The XDA forums people said along time ago that it was Flash Lite, and kept calling it Flash Lite, and not Flash Player 7.
    Now what about this:
    http://www.adobe.com/products/flashlite/version/
    The table shows the differences between FP 7 SDK, FL 2.1, and FL 3.1. And it's quite obvious that FL 3.1 has way more features than Flash Player 7. What does SDK mean? And why are you telling me FP 7 has more features?
    With this information, can you or anyone else provide any more details and clarification?

  • Difference between ALC Forms ES module and ALC Output ES module

    Hi,
    I would like to know if anyone has implemented just the Adobe Output ES module in any of the projects.
    I am into a project where we are integrating ALC with one of the insurance application for document generation and correspondence generation.
    Confused whether to go with Forms ES module, Output ES module or both?
    Can someone please throw light on these modules? I know there is info on the website but would like to know the advantages and disadvnantages of using either one of the module or both?
    If just Output module is used how will the insurance application interact with ALC?

    Jianghuai,
    The link you have gotten from Ivan provides great information sources.
    Note that those are not four different distributions, meaning linux-based operating systems, all are RHEL -- check out the FAQ, items 1 and 2. I would say main differences between family members are licensing and support offerings or subscriptions. AS, ES for "server" and WS, Desktop for the "desktop".
    "ES is licensed for servers with up to 2 CPUs and 16GB of main memory while AS is licensed for servers of any size and any architecture."
    Oracle products are generally not supported on the desktop variants.

  • HT1604 Is there any difference between Mac OS Extended Format and ExFat?

    Is there any difference between Mac OS Extended Format and ExFat?  I read in a blog that the ExFat was a good way to format an external drive because it avoided many of the pitfalls of the other formats, as long as it is supported by the operating system.  I tried to format my new Seagate drive, and got an invalid option error.  I was able to format it in Mac OS Extended format.  Can you please tell me if this is similar to ExFat.  Thanks.

    The Mac OS format can only be natively read to and written to by a computer running the Mac OS. This creates a problem if the user wishes his external, or other drive to have seamless compatibility between two different OS's, such as Windows and Mac. Yes, there are software solutions that enable a Windows PC to work with a drive formatted as Mac OS, but it gets complicated if you wish that drive to have compatibility "on the fly" with any PC you may encounter.
    It turns out that the format known as ExFAT is able to be natively read by both a Mac and a PC, without running any additional drivers on either machine. ExFAT also doesn't have some of the limitations of FAT32, which both OS's will also read/write.
    ExFAt is not perfect though. Formatting the drive as Mac OS Extended has some advantages on a Mac. First, it is the only format that permits all functionality of the Mac OS, such as using the drive for Time Machine.
    ExFAt is often thought of as the best middleground for an external partition/drive that needs to have easy cross platform compatibility between a Mac and  PC running Vista or Windows 7.

  • Difference between fully-specified data types. and generic types

    Hi,
    Can anyone tell me the difference between fully-specified data types and generic types.
    Thanks in advance.
    Regards,
    P.S.

    HI
    Generic table types
    INDEX TABLE
    For creating a generic table type with index access.
    ANY TABLE
    For creating a fully-generic table type.
    Data types defined using generic types can currently only be used for field symbols and for interface parameters in procedures . The generic type INDEX TABLEincludes standard tables and sorted tables. These are the two table types for which index access is allowed. You cannot pass hashed tables to field symbols or interface parameters defined in this way. The generic type ANY TABLE can represent any table. You can pass tables of all three types to field symbols and interface parameters defined in this way. However, these field symbols and parameters will then only allow operations that are possible for all tables, that is, index operations are not allowed.
    Fully-Specified Table Types
    STANDARD TABLE or TABLE
    For creating standard tables.
    SORTED TABLE
    For creating sorted tables.
    HASHED TABLE
    For creating hashed tables.
    Fully-specified table types determine how the system will access the entries in the table in key operations. It uses a linear search for standard tables, a binary search for sorted tables, and a search using a hash algorithm for hashed tables.
