How to clear the Entity Cache

I have an Entity based on a GLOBAL temp table. I have a ViewObject based on the Entity. A stored procedure is called from the client that populates the GLOBAL temp table and then calls executeQuery on the ViewObject. The first time the user does this, all rows display fine. When the user changes the selection criteria and clicks a button a 2nd time, the same procedure is called which clears the GLOBAL temp table and repopulates it with the new data. An exception occurs, however, stating that there are too many rows that match the key. The problem seems to be that the Enity has cached the rows from the first execute, but those rows aren't flushed when the 2nd execute is called, which makes sense. It seems that I just need to force the Entity to clear it's cache after my procedure is called, but before the executeQuery is called. I have tried that from the client side by calling clearCache on the view AND clearEntityCache on the transaction, but they don't seem to do anything. I have also called clear cache on the app module side in the method that calls the stored procedure, but it doesn't seem to do anything either. I also turned on the JBO debugging messages and I can't see any message stating that the Entity or View cache was cleared. It appears that these calls do nothing.
Is there a way to work around this to make the Entity/View chaches completely refresh from the database?
Thanks
Erik

Typically the client layer never has access to entities. This API is the one exception. The way to keep it cleaner would be to create a custom Application Module method, and inside that perform the clear cache, rather than burdening the client to have to know about any details of underlying entity objects. Keep that hidden.
I wouldn't think you should need to clear the entity cache to do what you're doing, though. If you have a reproducible test case -- with SQL script that creates your example global tempory table -- if you could create a TAR on Metalink and ask support to file a bug for it, that would be great so we can look into it.

  • How to clear the ADF Entity cache

    Hi All,
    While I'm using an entity based updatable view object,after deleting a record,I created a new record with the same key,It displays the deleted record instead of new record.
    Sample steps:
    1.Create a updatable view object with key attribute name sequence.
    2.I dropped this as table in the view page.
    3.I created a new record for this using CreateInsert action
    4.I entered the values for this new record.
    5.I deleted the new record
    6.Again I created a new record.
    7.If I enter the previous sequence value,it displays the old record values, If I enter a different value the delete record does not affect this.
    So I think,I need to clear the entity cache, but I have used clearCache() of ViewObjectImpl, there is no change.
    If anyone came across the problem and fixed,Please let me know the solution.
    Regards,
    Felix

    You are wrong here. if you don't commit the delete, the record is still there.
    You should not enter the same sequence again anyway. a sequence should be a one time number, once used it's gone. set the new key using a groovy expression and make it read inky in the ui.

  • Clear the weblogic cache

    Hi All
    Please let me know how to clear the Weblogic cache folder (ie. <bea_home>/user_projects/domains/<app_domain>/servers/
    <app_name>/tmp/_WL_user) upon each restart of the server?
    I am using Weblogic 9.1 and application is deployed using
    exploded mode
    Thanks.

    We have seen that error as well. When using entity beans, we could do some creates, but then we would get the Cursor error. It would happen sporadically.
    IBM now has better Type 4 drivers with version 8.2, we are having better luck with them then with the BEA drivers.

  • The Problem about clearing the system cache

    Hi, there!
    I'm trying to draw a lot of image in iPhone programming.
    I used [UIImage imageNamed].
    but it doesn't clear immediately the system cache.
    At last it occurs the out of memory.
    So I thought using imageWithContentsOfFile, but it works very slowly.
    Does anybody know how to clear the system cache?

    Read Position.flx can execute much faster than 5 ms but as it reads a register that is updated every 5 ms on the board, it reads the same value multiple times.
    To get around this problem there are two methods:
    Buffered High-Speed-Capturing (HSC)
    With buffered HSC the board stores a position value in it's onboard buffer each time a trigger occurrs on the axis' trigger input. HSC allows a trigger rate of about 2 kHz. That means, you can store a position value every 500 µs. Please refer to the HSC examples. You may have to look into the buffered breakpoint examples to learn how to use a buffer, as there doesn't seem to be a buffered HSC example available. Please note that you need an external trigger-signal (e. g. from a counter of a DAQ board). Please note that the amount of position data that you can acquire in a single shot is limited to about 16.000 values.
    Buffered position measurement with additional plugin-board
    If you don't have a device that allows you to generate a repetitive trigger signal as required in method 1.), you will have to use an additional board, e. g. a PCI-6601. This board provides four counter/timers. You could either use this board to generate the trigger signal or you could use it to do the position capturing itself. A PCI-6601 (or an M-Series board) provides can run a buffered position acquisition with a rate of several hundred kHz and with virtually no limitation to the amount of data to be stored. You could even route the encoder signals from your 7350 to the PCI-6601 by using an internal RTSI cable (no external wiring required).

  • How to clear the cache in the portal browser

    Hello Experts,
    Iam unable to clear the cache in the portal. I tried  clearing the Navigation cache , PRT cache,PCD cache,Database cache,UME cache.
    The senario is in the browser if iam logging with some user X , he should see only 1,2,3 countries, and if i logg off and again logg in the same browser with different user he is seeing same 1,2,3 countries unlike he should see 4,5 countries.
    But if iam opening in different browser iam getting the correct one with cache cleared.
    I want to acheive this in the same browser.
    Qucik help in solving out this cache problem is appreciable.
    Regrds,
    Manasa.

    There is one more important cache: the HTTP Provider Service cache (in VA).
    To find out why the browser is showing the same languages, analyze what the server is sending to the browser with HTTPWatch or Firebug and look at the cache flag. Also check what is the iView cache parameter? Is it user, session, shared or none?
    How do you do the logoff? The best thing is to make sure that the HTTP Session is killed. If not, the portal may send data that is cached for the HTTP Session to the browser. When you open a new browser, you will also open a new HTTP Session. That could be the cause why it is working with a new browser instance.

    Is there anyway to clear a particular user from the cache. When the user's
    password
    is changed in the database, i would like to remove this user from the
    Caching
    realm. If i call authUserPassword() with incorrect password, will it
    remove the
    User object from Cache?
    Also, in a cluster, how do i remove the User from all WLS instances.
    thanks for your help.

    import weblogic.security.acl.Realm;
    import weblogic.security.acl.Security;
    import weblogic.security.acl.CachingRealm;
    Realm genericRealm = Security.getRealm();
    CachingRealm cachingRealm = (CachingRealm)genericRealm;

  • How to clear the cache files in folder Temporary Internet Files

    When one user opens files such as pdf. or doc. from Portal,  the same file will be downloaded into the Temporary Internet Files folder. if another user copied the files out of the Temporary Internet Files folder from this computer and save to someplace else, then we face one security problem.
    So my question is: How to clear the cache files in folder Temporary Internet Files??  Can we delete the files automatically when close the files in Portal??
    or is there some ways to make encrypty???
    Thanks very much!

    Hello,
    this is a basical security problem which should be resolved by the OS standard security setup . No other user should have access to the temporary file folders in the personal directory. The user account must be secure. Normaly your security problem should not be a problem if basic security exists on the clients.
    You can resolve this problem if every user has his own account on the client
    The users having no administration permissions on the clients
    The folder for the temporary internet files is placed in the personal profile folder of the user account.
    On default no other user has access rights to you personal folder, this means the client OS is setup correctly.
    You can setup the IE that no temporary files are saved (but it reduces performance)
    You can enable IE to delete automaticly the temporary files if IE is closed.
    Hope it helps.
    Regards
    Alex

  • How to clear the OTHER memory cache

    Hi there fire fox help,
    I have read the page on 'How to clear the cache' but this does not seam to clear everything.
    When I am editing a website on my computer and viewing the changes through fire fox everything works great, I just hit refresh.
    But when testing the websites changes online (after unloading it) I can not see any changes, using the refresh button is of no help and clear the cache is not helping either.
    I get quite frustrated with this as I then have to change the name of the web page just to get fire fox to refresh it properly and then change it back again.
    Thanks for your time, Max

    I've tried all these and Firefox still won't load the current image. I know it's there because Internet Explorer does load it. Is there anything else I can try or look at?

  • How can I clear the DNS cache?

    I haven't been able to connect to my local Library since January.  When I key in the URL, it starts the access routine and then after about 20 minutes, I have to kill it because nothing happens.  I contacted the IT folks at the library and was told that they had made a few changes around the time my problem began so maybe the DNS cache was still pointing at the old info.  He recommended that I enter TERMINAL mode and try to clear the DNS cache, using  "sudo dscacheutil -flushcache" command.   .  I attempted this several times, even changing my applid password, and kept getting invalid responses.

    I did try that and after a few trys it finally worked.  It took quite awhile for the window for the library to finally come up, but it did and I am now able to get in and out with no problems with my library access.  Now when I call up my bank, parts of it don't come up and it kicks me out.  Now, I'll have to search for what fixes that - as it has happened before, so I know it's fixable.  Thanks for you help though.

  • 10G NEW FEATURE-HOW TO FLUSH THE BUFFER CACHE

    제품 : ORACLE SERVER
    작성날짜 : 2004-05-25
    10G NEW FEATURE-HOW TO FLUSH THE BUFFER CACHE
    ===============================================
    PURPOSE
    이 자료는 Oracle 10g new feature 로 manual 하게
    buffer cache 를 flush 할 수 있는 기능에 대하여 알아보도록 한다.
    Explanation
    Oracle 10g 에서 new feature 로 소개된 내용으로 SGA 내 buffer cache 의
    모든 data 를 command 수행으로 clear 할 수 있다.
    이 작업을 위해서는 "alter system" privileges 가 있어야 한다.
    Buffer cache flush 를 위한 command 는 다음과 같다.
    주의) 이 작업은 database performance 에 영향을 줄 수 있으므로 주의하여 사용하여야 한다.
    SQL > alter system flush buffer_cache;
    Example
    x$bh 를 query 하여 buffer cache 내 존재하는 정보를 확인한다.
    x$bh view 는 buffer cache headers 정보를 확인할 수 있는 view 이다.
    우선 test 로 table 을 생성하고 insert 를 수행하고
    x$bh 에서 barfil column(Relative file number of block) 과 file# 를 조회한다.
    1) Test table 생성
    SQL> Create table Test_buffer (a number)
    2 tablespace USERS;
    Table created.
    2) Test table 에 insert
    SQL> begin
    2 for i in 1..1000
    3 loop
    4 insert into test_buffer values (i);
    5 end loop;
    6 commit;
    7 end;
    8 /
    PL/SQL procedure successfully completed.
    3) Object_id 확인
    SQL> select OBJECT_id from dba_objects
    2 where object_name='TEST_BUFFER';
    OBJECT_ID
    42817
    4) x$bh 에서 buffer cache 내에 올라와 있는 DBARFIL(file number of block) 를 조회한다.
    SQL> select ts#,file#,dbarfil,dbablk,class,state,mode_held,obj
    2 from x$bh where obj= 42817;
    TS# FILE# DBARFIL DBABLK CLASS STATE MODE_HELD J
    9 23 23 1297 8 1 0 7
    9 23 23 1298 9 1 0 7
    9 23 23 1299 4 1 0 7
    9 23 23 1300 1 1 0 7
    9 23 23 1301 1 1 0 7
    9 23 23 1302 1 1 0 7
    9 23 23 1303 1 1 0 7
    9 23 23 1304 1 1 0 7
    8 rows selected.
    5) 다음과 같이 buffer cache 를 flush 하고 위 query 를 재수행한다.
    SQL > alter system flush buffer_cache ;
    SQL> select ts#,file#,dbarfil,dbablk,class,state,mode_held,obj
    2 from x$bh where obj= 42817;
    6) x$bh 에서 state column 이 0 인지 확인한다.
    0 은 free buffer 를 의미한다. flush 이후에 state 가 0 인지 확인함으로써
    flushing 이 command 를 통해 manual 하게 수행되었음을 확인할 수 있다.

  • How to clear webdynpro ABAP cache ?

    Hi,
    Please advise me on how to clear webDynPro ABAP Cache data ?
    Scenario as most of you might be knowing:
    1>We retreive data from the the table using query stmt. For ex: Creating an employee
    2>When we want to update/terminate the same employee on same day giving us short dump
    We checked in the backend that employee has been sucessfully onboarded and offboarded/updated without any dump.
    I guess it has something to do with clearing the cache/memory on each operation(create/update/delete)
    So, I got some transaction code:SWFVISU where we can maintain the cache configuration. But I'm not sure whether we can use the same.
    Is there anyway we can avoid the cache issue.
    Thanks
