Optimal NTFS block size for Oracle 11G on Windows 2008 R2 (OLTP)

Hi All,
We are currently setting up an Oracle 11G instance on a Windows 2008 R2 server and were looking to see if there was an optimal NTFS block size. I've read the following: http://docs.oracle.com/cd/E11882_01/win.112/e10845/specs.htm
But it only mentioned the block sizes that can be used (2k - 16k). And basically what i got out of it, was the different block szes affect the max # of database files possible for each database.
Is there an optimal NTFS block size for Oracle 11G OLTP system on Windows?
Thanks in advance

Is there an optimal NTFS block size for Oracle 11G OLTP system on Windows?ideally FS block size should be equal to Oracle tablespace block size.
or at least be N times less than Oracle block size.
For example - if Oracle BS=8K then NTFS BS better to be 8K but also can be 4K or 2K.
Also both must be 1 to N times of Disk sector size. Older disks had sectors 512 bytes.
Contemporary HDDs have internal sector size 4K. Usually.

    Hello,
    I am looking for Oracle Golden gate 10.4 for my demo/poc. Is this available for download from oracle.
    I could not find the OGG 10, if any one has the link, please let me know.
    Thanks,

    Have you looked in Edelivery?
    Oracle Fusion Middleware, Windows 32-bit, media pack for GoldenGate (at the bottom of the page), then pick the release for Oracle 10g or 11g

  • Performance problems on a Oracle 11G with Windows 2008 64bits.

    Hi everyone,
    I have noticed that our db is going low and low every week. My server has 16GB RAM and 10GB are dedicated to the Oracle database, this is a 11.2.0.1 with Windows 2008 R2 SP1 64bits. I like to know acording to the nexts values what you guys recommend to adjust in the init.ora:
    orcl.__db_cache_size=5402263552
    orcl.__java_pool_size=33554432
    orcl.__large_pool_size=33554432

    *.memory_target=10511974400
    *.open_cursors=5000
    *.optimizer_mode='RULE'
    *.processes=300
    Acording to the memory target on how values can be increased the processes, pga_agregate_target, etc.
    Also we have problems related to the bug Bug 9593134 that “Connections to Oracle 11g are slow and can take anywhere from 10 seconds to 2 minutes.” there is a fix on linux by removing the dns names on it but anyone have experience on windows platforms?
    Thanks for all and sorry for my english.
    Regards.
    Arturo.

    Regarding the long connection times, have you tried using network packet capture software (such as Wireshark) to determine what the client computer is doing when a connection attempt is initiated?
    The Oracle Database time model statistics, along with the system wide wait events may help you diagnose the non-connection related performance issues (you should not just look at the statistics, but instead capture the current values, wait a period of time, capture the statistics again, and compare the changes in the statistic values). A statspack report might also help you - but a 10046 trace at level 8 or 12 is more appropriate if you are able to identify a couple of sessions that experience performance problems.
    I do not suggest just blindly modifying parameters, although I am curious to know:
    * Why the session level parameter OPEN_CURSORS is set to 5000 - do you expect a single session to hold open 5,000 cursors?
    * Why are you using the deprecated RULE based optimizer?
    * Why is the MEMORY_TARGET parameter used when the SGA_TARGET and PGA_AGGREGATE target are specified?

  • Oracle Client 10g/11g on Windows 2008, Itanium

    Hi, All!
    I need to install Oracle Client on test Windows 2008 Server, based on Itanium processors.
    11g client is preferred, and 10g client at least.
    I know, that Win2008 is not supported yet for Oracle Database, but, may be, there are way to install it on my own risk (its test server).

    Sorry for coming back late on this thread... I have installed Oracle 11g on Windows 2008 but it was a Xeon processor not Itanium.
    On a side note, am I wrong in saying Oracle should not be bothered about the underlying hardware (whether Intel or AMD or any proprietary hardware)? It is then the responsibility of the operating system to ensure that the product behavio(u)r is same across platforms.

  • Optimal Block Size for Xserve's RAID hosting Final Cut Server

    What would be the optimal block size for the software RAID on the machine that will be hosting Final Cut Server? The default is 36K. Since FCS is essentially a database, would be the optimal settings? Any glimpse what data size chunks FCS write to the disk?

    Actually I meant the block size for the internal startup volume where FCS is installed, not Xsan volumes. As to optimal settings for Xsan volumes it really depends on the type of the data you store on Xsan, and if it is primarily video, what format: SD, HD.

  • Using large block sizes for index and table spaces

    " You are not using large blocksizes for your index tablespaces. Oracle research proves that indexes will build flatter tree structures in larger blocksizes.
    Is this a generic statement that I can use for all tables or indexes? I also have batch and online activity. My primary target is batch and it should not impact online. Not sure if both have common tables.
    How to find the current block size used for tables and index? is there a v$parameter query?
    What is an optimal block size value for batch?
    How do I know when flatter tree str has been achieved using above changes? Is there a query to determine this?
    What about tables, what is the success criterion for tables. can we use the same flat tree str criterion? Is there a query for this?

    Is this a generic statement that I can use for all tables or indexes? This is a generic statement used by some consultants. Unfortunately, it is riddled with exceptions and other considerations.
    One consultant in particular seems to have anecdotal evidence that using different block sizes for index (big) and data (small) can yield almost miraculous improvements. However, that can not be backed up due to NDA. Many of the rest of us can not duplicate the improvements, and indeed some find situations where that results in a degradation (esp with high insert/update rates from separated transactions).

    1) stop using generic tools to analyze specific problems
    2) define you problem in detail ()what are you really trying to accomplish - seems like performance tuning, but you never really state that)
    3) define the OS and DB version - in detail. Give rev levels and patch levels.
    If you are having a serious performance issue, I strongly recommend you look at some performance tuning specialists like "http://www.method-r.com/", "http://www.miracleas.dk/", "http://www.hotsos.com/", "http://www.pythian.com/", or even Oracle's Performance Tuning consultants. Definitely worth the price of admission.

    Thanks.

    "connection refused" is quite a clear error message;
    - either you configure a wrong host name or port number
    - the database isn't even running
    - a firewall is blocking you
    In any case no connection can be made to the database, which is hardly a programming or driver problem. You'll have to figure out for whatever external reason you cannot create a connection to the database. Good luck.

  • Procedure for creating logical standyby database for oracle 11g?

    Hi all,
    can anybody provide me docs /procedure for creating logical standby databse for oracle 11g standard edition.
    Aravind

    Aravind,
    1. The Oracle Standard Edition does not have standby mechanism, you should do it manually or go for Enterprise Edition.
    2. It's rather a question for General Database Discussions instead of Peoplesoft.
    Any further question regarding that point, please post out there.

  • Choosing block size for RAID 0 & Final Cut

    Hi.
    I now have 3 500GB internal Seagate drives in bays 2/3/4 and want to make a striped 1.5TB RAID to use with Final Cut Studio 2. The help page talks about choosing a "large" data block size for use with video, but makes no specific size suggestion. What value would you recommend that I select for the block size? I haven't been in there yet so I don't know what the choices are.
    Any other settings I should be aware of that will optimize the RAID performance for video capture and editing? Thanks!

    If you're using Disc Utility to set up your RAID, when you go to the RAID tab, you'll see an options button near the bottom of the window... clicking this will open a small menu where you can set the data block size... the largest is 256K, which is what you'd want to use.
    As for you're other question... have a look at this website: http://bytepile.com/raid_class.php
    note that disc utility can only set up RAID 0 & RAID 1 (if i remember rightly).
