Clearing Data Buffer Pools

Is it possible to clear the buffer pool in Oracle without bouncing the database? We are configuring our database to use the keep buffer pools, and I wanted to test the performance improvements with pinning different tables into the keep buffer. Unfortunately the only way I can clear the buffer is to bounce the database, which disrupts several other people. I was hoping there was something like the "alter system flush shared_pool" to do this.
Any help would be greatly appreciated...

Any help would be greatly appreciated... i guess there is no straight forward method like 'flush shared pool'
maybe you can try running a full table scan or a cartesian join on two large tables
which will flush the buffers of the tables that you are trying to tune.
this is exactly the situation why you want to go for 'keep' buffer pool.

  • How to configure params for buffer pool for named data cache?

    when create a named data cache on ase 12.5, it will setup 2K I/O buffer pool by default with Configured size=0, wash size = 60M
    1. if 2K can be changed to 8K for this buffer pool?
    2. If add another 16k buffer pool, should Affected Pool be changed to the right pool?
    3. How to decide then pagesize, configured size and wash size for a buffer pool? Are they part of total memory size allocated for this cache?

    > 1. if 2K can be changed to 8K for this buffer pool?
    You should be able to create an 8K i/o pool, then drop the 2k pool by setting its size to 0.
    > 2. If add another 16k buffer pool, should Affected Pool be changed to the right pool?
    If you don't specify the Affected Pool (when calling sp_poolconfig), the procedure uses the pool with the smallest i/o.  So if you had an 8k but not had dropped the 2k, the space for the new 16k pool would come from the 8k pool.
    > 3. How to decide then pagesize, configured size and wash size for a buffer pool? Are they part of total memory size allocated for this cache?
    The wash is included in the pool. I don't think it usually needs to be adjusted.
    Which page size pools to have will depend on how the cache is used.  Tables with a clustered index that have a lot of range queries will benefit from larger page size pools, as will text/image/java.   Syslogs is said to do well on a 4k pool.

  • Is there any way exsit to drop database specific data buffer from buffer pool.

    hi,
       Is there any way exist to drop one data buffer(DBCC DROPCLEANBUFFERS)
    .like DBCC FLUSHPROCINDB( db_id )
    yours sincerely.

    hi,
       Is there any way exist to drop one data buffer(DBCC DROPCLEANBUFFERS
    You can selectively flush plans from buffer pool, not all cache objects related to database . See

  • Query about Keep Buffer Pool and Recycle Buffer Pool

    What will Keep Buffer Pool and Recycle Buffer Pool contains actually in Database Buffer Cache, specially what type of objects? I know the definitions but need to know the practical aspects about them.

I know the definitions but need to know the practical aspects about them.I believe you have already got the answer from the experts. Just to echo the same, in any cache, either Buffer Cache(default), Keep or Recycle, its going to be data buffers which are actually the placeholders for the data blocks that are available on the disk. The default cache is going to throw away the lesser used buffers as fast as possible. And if you don't want this to happen, you can use either of the other two, indepandant caches-Recycle and Keep. The keep cache , as the name suggests would keep the buffers in it for a more loonger duration compared to the default cache. This probably would be a better idea when you know that some buffers are meant to be reused again and again. Recycle is going tobe for those, which are very seldom used and you don't want them to choke up the caches at all. For the buffers kept in the Recycle cache, they would be thrown out almost instantly.
    Read the link that's given to you. It contains a lot of stuff that would further make things clear.

  • Data Buffer Cache Limit

    Is there any way that I could signal daat buffer cache to write all data to data files if amount of dirty blocks reach say 50 Mb.
    Iam processing with BLOBS, one blob at a time, some of which has sizes exceeeding 100 Mb and the diffcult thing is that I cannot write to disk until the whoile blob is finished as it is one transaction.
    Well if anyone is going to suggest that to open, process close, commit ....well i tried that but it also gives error "nmo free buffer pool" but this comes for twice the size of buffer size = 100 Mb file when db cache size is 50 mb.
    any ideas.

  • Multiple Buffer Pools Feature

    Have somebody used it and what are your comments?
    I have very high activity for specific tables growing over 15-20 mnl of records. Many inserts and few select. very optimized SQL but still slower then the same code on DB2.
    I would like to separate may be temp tablespace, and a few tables I never select from - like log and audit tables.
    Will multiple Buffer Pools be beneficiary for me?
    Thanks,

    Thanks a lot - Yes, your assumption is absolutely right - the application always reports much higher time then I could see from the Oracle side even when I add all SQLNet waits. The same time on Db2 is approximatelly equal - again, the app reported time is a little bit higher, but it's not 250 times difference like in Oracle.
    The app is 3rd party and get a lot of data in and out. The app structure is: Reading XML file and inserting the values in common tables like Address, Name, etc. As a next step the application will check if these records already exist and will perform specific logic if previous entries are found. From Oracle point these are multiple selects and few possible updates and/or inserts. After all processing is done a record in a log table will be inserted and the transaction is commited. Then the app gets the next XML record. This is single threaded process repeating over and over again. The capacity is about 25,000 records inserted per minute with about 40 application instances running simultaneously. if I increase the number of app instances running against DB2 to 100, the insert rate jumps to 60-65,000/min. In Oracle is the opposite - the increase of the app processes more then 45-50 do not change the insert rate at all. Even on SQL server I can run about 70 processes... So, something is wrong with the way Oracle process runs. These results are not new and have been run on at least 30 different hardware setups for months -AIX, linux, Solaris, windows, and on differnet type of hardware. This is the result for all of them. Everybody who tried the app reports the same case. Most of this cases though do not have well tuned environment... That's why I'm trying to make it work better - could not be "just doesn't run!!!" - Oracle is a great scalable system!
    I've already thought to run the app locally on the server, but it's very hard as the usual set up takes about 3-4 hours and the app is very CPU consuming. But for a single app instance it'll work.
    I think your idea is great and I must do it. Let me do that first thing on Monday and I'll post the results.
    Thanks a lot,

    this is more of a open question. As you know ur data well. We do not know whats ur data. cachin tables in buffer pool is okay, but it might age out after not being used...instead you can use the KEEP POOL...to cache small tables/popular tables into the keep pool...as keep pool guarantees full caching .....

    Re,
    OK it makes it a little bit clearer.
    What I now think to understand is that the "Estimated Phys Reads (thousands) no represents the
    current workload of the system it only gives clue that there will be a change around 3 times more blocks was red.
    Right ?
    But if it is like that why these numbers are changing from one to another report....
    So again another image.... Maybe my problem is that I try to set the current workload (phys block reads) in comparison with the "Estimated Phy Reads from the Advisory....
    Our AWR reports are generated every hour.

    I searched for the Flush Return Data Buffer.vi in the Labview library but it is not there.
    Where can I find it?

    Hello Mishka,
    The Flush Return Data Buffer.vi should be located in your functions palette at Vision and Motion>>73xx>>Advanced>>Flush RDB.vi. Alternatively, you can press ctrl+space on your keyboard to open the quick drop menu and then search for Flush RDB.vi.

  • Posting date and clearing date different in G/L clearing document

    Hi Friends,
    While clearing a G/L manually using F-03, the clearing date is entered in the selection screen.
    The clearing document which is posted is posted with the posting date same as the clearing date mentioned in the selection screen of F-03.
    In what situations can the posting date of a G/l clearing document be different from the clearing date?
    Regards,
    Shilpi

    Hi,
    The Clearing Date in F-03 is actually the Posting date, so in this case the posting date will be same as clearing date. But a clearing document can also be created when you reverse a FI document, in this case the Reversal document will have a clearing date different than posting date. Let me know if this info helps you
