How to reduce db block get

i am running following query
select 1 from
     select PRD_SEARCH_ID, ROW_NUMBER() OVER (PARTITION BY PRD_SEARCH_COMPANY_ID ORDER BY SCORE(1) DESC) AS RK
     from prd_search
     where CONTAINS(DUMMY,FN_MK_SEARCH_CLAUSE_PRD('Chemical Manufacturing', 'I'),1) > 10
     and score(1)>25
     and decode(prd_search_clnt_enabled,1,1,2,1,3,1,0) = 1
where rk<=3;
Statistics
720 recursive calls
198091 db block gets

12015 physical reads
0 redo size
217566 bytes sent via SQL*Net to client
9771 bytes received via SQL*Net from client
843 SQL*Net roundtrips to/from client
1 sorts (memory)
0 sorts (disk)
12620 rows processed
after sm analysis i came to know that when i remove the condition
where rk<=3;
the db block gets reduced to zero..
plz help

Can you give the Explain pan with the stats for quer with rk <= 3 and without rk <= 3
And please use {noformat}{noformat} tag to preserve your code format.
And please provide your db verstion.

  • My iphone its block it seds  that it needs a sim card how or where do i get the sim card because it was working yesterday and today was block?

    my iphone its block it seds that it needs a sim card how or where do i get the sim card because it was working yesterday and today got block???

    Does it have a SIM card in it? You get the SIM card from your cellular carrier. Did you update the phone or restore it since it worked last? Where are you and what carrier are you on? Where did you get the phone?
    It sounds like the phone may be carrier locked and was previously hacked to work on a different carrier. If it was re-set, it would cause the phone to re-lock to the original carrier.

  • I have suddenly been getting a lot of fraud emails.  Does anyone know how to set up blocks?

    Hello,
    I have been suddenly getting tons of fraud emails.  This has never been a problem in my mack mail in the past. Does anyone know how to set up blocks?  I have searched through preferences but have not been able to find any way to do it.  Bounce is of no use as these emails are not "respondable".

    i can't seem to get my iPad to synch with my new iMac.  The iTunes prompt says that this computer isn't authorised although i have registered it on iTunes.  Any other ideas for how to overcome this block?

    What do you mean by 'registered it on iTunes' ? You've authorised your account on your Mac's iTunes via the Store > Authorise This Computer menu option ? And you've copied your library onto the Mac ?

  • How to reduce buffer gets

    Dear All,
    My query is taking 575,618,610, executions 86,114 and CPU Time is 3982.59s which i found in the statspack report.
    Then i checked the query to tune, but it's execution plan is showing only CPU cost 5.
    So, what is the problem and what is the solution. Please let me know.
    Thanks in advance
    Mahi

    Hi Richard Foote,
    The below is the function, in that i am using a cursor with the SQL in Bold letters.
    That SQL query is taking more buffer gets as i expalined previously.
    FUNCTION get_shortcuts(
    p_org_id IN VARCHAR2,
    p_usr_id IN VARCHAR2,
    p_sws_id IN VARCHAR2,
    p_lan_id IN VARCHAR2)
    RETURN pglobal.g_ref_cur
    AS
    c_1 pglobal.g_ref_cur;
    BEGIN
    IF NVL(p_lan_id, 'ENG') = 'ENG' THEN
    OPEN c_1
    FOR
    SELECT amnu.url_value, swssh.sws_id_1, sws.title

    AND sp.rol_org_id = p_org_id
    AND sp.sws_id = sws.id
    AND sws.id = swssh.sws_id_1
    AND sws.sws_id = amnu.sws_id
    AND EXISTS(SELECT rol_id
    FROM USER_ROLES
    WHERE rol_org_id = p_org_id
    AND usr_id = p_usr_id
    AND rol_id = sp.rol_id); ELSE
    OPEN c_1
    FOR
    SELECT sws.url_value, swssh.sws_id_1, sws.title
    FROM SOFTWARE_SERVICE_SHORTCUTS swssh,
    SERVICE_PROVISIONS sp,
    SOFTWARE_SERVICES sws,
    SOFTWARE_SERVICE_LANGUAGES swsl
    WHERE swssh.sws_id = p_sws_id
    AND swssh.sws_id_1 = sp.sws_id
    AND swsl.sws_id = sws.id
    AND swsl.lan_id = p_lan_id
    AND sp.rol_id = p_org_id
    AND sp.sws_id = sws.id

    GROUP BY sws.url_value, swssh.sws_id_1, sws.title;
    END IF;
    RETURN c_1;
    END;
    So, please can u explain me is there any possiblity to reduce the buffer gets after checking the above function.

            OR ims_trde.ssc_invst_type = 'FC')
    AND    ims_trde.service_type = 'FS'or is it maybe:

    I am seeing a very high clustering factor on an SDO geometry table in our 10g RAC DB on our Linux boxes. This slow performance is repeateable on othe r Linux as well as Solaris DBs for the same table. Inserts go in at a rate of 44 milliseconds per insert and we only have about 27000 rows in the table. After viewing a VERY slow insert of about 600 records into this same table, I saw the clustering factor in OEM. The clustering factor is nearly identical to the # rows in the table indicating that useability of the index is fairly low now. I have referenced Metalink Tech Note 223117.1 and, while it affirms what I've seen, I am still trying to determine how to reduce the Clustering Factor. The excerpt on how to do this is below:
    "The only method to affect the clustering factor is to sort and then store the rows in the table in the same order as in they appear in the index. Exporting rows and putting them back in the same order that they appeared originally will have no affect. Remember that ordering the rows to suit one index may have detrimental effects on the choice of other indexes."
    Sounds great, but how does one actually go about storing the rows in the table in the same order as they appear in the index?
    We have tried placing our commits after the last insert as well as after every insert and the results are fairly neglible. We also have a column of type SDE.ST_GEOMETRY in the table and are wondering if this might also be an issue. Thanks in advance for any help.
    Matt Sauter

    Joel is right that the clustering factor is going to have absolutely no effect on the speed of inserts. The clustering factor is merely one, purely statistical, factor the optimiser makes use of to determine how to perform a SELECT statement (i.e., do I bother to use this index or not for row retrieval). It's got nothing to do with the efficiency of inserts.
    If I were you, I'd be looking at factors such as excessive disk I/O taking place for other reasons, inadequate buffer cache and/or enqueue and locking issues instead.
    If you're committing after every insert, for example, then redo will have to be flushed (a commit is about the only foreground wait event -i.e., one that you get to experience in real time- that Oracle has, so a commit after every insert's really not a smart idea). If your redo logs are stored on, say, the worst-performing disk you could buy that's also doing duty as a fileserver's main hard disk, then LGWR will be twiddling its thumbs a lot! You say you've tested this, and that's fine... I'm just saying, it's one theoretical possibility in these sorts of situations. You still want to make sure you're not suffering any log writer-related waits, all the same.
    Similarly, if you're performing huge reads on a (perhaps completely separate) table that is causing the buffer cache to be wiped every second or so, then getting access to your table so your inserts can take place could be problematic. Check if you've got any database writer waits, for example: they are usally a good sign of general I/O bottlenecks.
    Finally, you're on a RAC... so if the blocks of the table you're writing to are in memory over on another instance, and they have to be shipped to your instance, you could have high enqueue waits whilst that shipment is taking place. Maybe your interconnect is not up to the job? Maybe it's faulty, even, with significant packet loss along the way? Even worse if someone's decided to switch off cache fusion transfer for the datafiles invoved (for then block shipment happens by writing them to disk in one instance and reading from disk in the other). RAC adds a whole new level of complexity to things, so good luck tracking that lot down!!
    Also, maybe you're using Freelists and Freelist groups rather than ASSM, so perhaps you're fighting for access to the freelist with whatever else is happening on your database at the time...
    You get the idea: this could be a result of activity taking place on the server for reasons completely unconnected with your insert. It could be a feature of Spatial (with which not many people will be familiar, so good luck if so!) It could be a result of the way your RAC is configured. It could be any number of things... but I'd be willing to bet quite a bit that it's got sod-all to do with the clustering factor!
    You'll need to monitor the insert using a tool like Insider or Toad so you can see if waits and so on happen, more or less in real time -or start using the built-in tools like Statspack or AWR to analyze your workload after it's completed- to work out what your best fix is likely to be.

  • Consistent gets and db block gets

    Hi...
    I wanted to know the difference between consistent gets and db block gets in v$sess_io.I have read that consistent gets is the blocks in consistent mode..so here what does consistent mode means????
    Thanks in Advance,
    Anand

    Here's the complete text of the answer I originally wrote nearly 5 years ago on the Oracle-L mailing list:
    A 'db block get' is a current mode get. That is, it's the most up-to-date copy of the data in that block, as it is right now, or currently. There can only be one current copy of a block in the buffer cache at any time. Db block gets generally are used when DML changes data in the database. In that case, row-level locks are implicitly taken on the updated rows. There is also at least one well-known case where a select statement does a db block get, and does not take a lock. That is, when it does a full table scan or fast full index scan, Oracle will read the segment header in current mode (multiple times, the number varies based on Oracle version).
    A 'consistent get' is when Oracle gets the data in a block which is consistent with a given point in time, or SCN. The consistent get is at the heart of Oracle's read consistency mechanism. When blocks are fetched in order to satisfy a query result set, they are fetched in consistent mode. If no block in the buffer cache is consistent to the correct point in time, Oracle will (attempt to) reconstruct that block using the information in the rollback segments. If it fails to do so, that's when a query errors out with the much dreaded, much feared, and much misunderstood ORA-1555 "snapshot too old".
    As to latching, and how it relates, well, consider that the block buffers are in the SGA, which is shared memory. To avoid corruption, latches are used to serialize access to many linked lists and data structures that point to the buffers as well as the buffers themselves. It is safe to say that each consistent get introduces serialization to the system, and by tuning SQL to use more efficient access paths, you can get the same answer to the same query but do less consistent gets. This not only consumes less CPU, it also can significantly reduce latching which reduces serialization and makes your system more scalable.
    Well, that turned out longer than I planned. If you're still reading, I hope it helped!
    Hope that helps,
    -Mark
    PS The original question asked about latching as well, which explains the reason for the third paragraph.

  • How to Reduce the Gate count of a Design(RTL gate count)

     
    Hi All,
    I am a newbie to FPGA design and implemetation. I have a design (H.264 Encoder) and implemented on zynq zc702 (which is having Artix7 FPGA fabric). Now we need to implement it on zynq zc706 with reduced gate count ( because we are going to add some more blocks like rate control etc.,)
    How to reduce the gate count ?
    Please guide me regarding this query.
    Thanks,
    Ramesh

    
    Try to reduce the overall control set. Registers in the slice shares the same control set so if the number of registers in the control set do not divide cleanly, some registers may go unused.
    Make sure correct DSP and BRAM blocks are getting inferred by the tool
    Try to map FSM in BRAM.
    Use Synthesis and Implementation level strategies.
    See if any module is having high utilization and can be reduced by changing RTL: report_utilization -hierarchical  -file utilization.txt
    Thanks,
    Anusheel

  • How to create a block key default for documents created by MIRO?

    Hi All,
    How to create a block key (BSEG-ZLSPR) default for documents created by MIRO?
    Could anyone tell me?
    Thanks
    Gandalf

    HI,
    The payment block--BSEG-ZLSPR can be made defaulted by two  ways.
    Means you want to fix one value all the times for the same ,you have to do the same in Vendor master
    ie in the Vendor Master in the Payment Transactions Selection screen. make the Payment Block you want to be defaulted in MIRO.
    you can do for all vendor master in mass change -- XK99.(LFB1)
    if you are not OK with the Above .then there is another way to do the same
    it is by Screen layout setting in SHD0
    in this enter the Transaction MIRO and create a Transaction variant Z*** and click on create
    and also create a Screen variant in OMLRLIST 
    T code MIRO
    Screen variant name Z**
    Program-SAPLFDCB
    Screen Number 0020
    and create it .
    in creating ---enter the default value in the Payment block and in the varinat just check the box w.content
    KNow in SHd0 add this screen variant for the above Trasaction variant
    and then activate this trasaction variant by going into the tab Standard variants.
    so that when ever you do miro this variant will be called and you can get this payment block defaulted.
    hope so it helps

  • How to reduce buffer busy waits, session hanging due to buffer busy waits

    Hi,
    How to reduce buffer busy waits, session hanging due to buffer busy waits.
    Thanks,
    Sathis.

    When I see through enterprise manager I see lot of
    tables with buffer busy waits.
    Is there any way by table name we can check the
    blocks info.
    The simple way is to look at the SQL statement and corresponding table name?
    P1=file#, P2=block#. You can extract segment name(table or index) using this info.
    Query v$bh like following:
    SQL> select file#, block#, class#, objd from v$bh where file# = P1 and block# = P2;
    SQL> select object_name from all_objects where object_id = <objd>;See following doc:
    http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14237/dynviews_1051.htm
    Or you can dump block:
    SQL> alter system dump datafie <P1> block <P2>;Some excerpts from block dump:
    scn: 0x07df.17e70782 seq: 0x01 flg: 0x04 tail: 0x07822301
    frmt: 0x02 chkval: 0x61d0 type: 0x23=PAGETABLE SEGMENT HEADER
    Map Header:: next  0x00000000  #extents: 1    obj#: 55881  flag: 0x10000000>
    Can we do something at table level that will reduce
    the waits.
    Yes, some methods are known. But before thinking of that, you must verify which block class and which access are involved.
    Typo... always. :(

  • How to download the blocked ALV output to PDF file.

    How to download the blocked ALV output to PDF file.
    I am able to download the BLocked ALV output in PDF format,
    but the each bolck in ALV is displaying different pages of PDF.
    In my report I have 4 block in 1 page, I am able to see the output in PDF but in different page.
    How to avoid the Page-break in PDF.
    Thanks,
    Ravi Yasoda.

    hi,
    I believe that your have 4 containers on the screen with individual ALV display. in this case, there is no way to get combined PDF output to my knowledge.
    However you can use Smartform/Sapscript as output which would allow you to display ALV in blocks and also print it in one.
