CONS-10049: Consolidator Exception: ORA-01562: failed to extend rollback segment
number 5
ORA-01650: unable to extend rollback segment R04 by 256 in tablespace RBS
How does one calculate the size of the rollback segment so as to avoid the above error?

    Hi,
    in our application log, we got sometimes an error ORA-01562: failed to extend rollback segment number 4 and the application hangs and some transactions are blocked. checking the aler database file, we don't found this error but it's appearing often in our system.
    would you lease advise what to do to avaoid this error, or is there a script to find oracle SQl where using too much rollback segment.
    My configuration is : Oracle 10g r2 in linux SUSE.
    thank you

  • ORA-01562: failed to extend rollback segment

    HI
    I was searching the forum for an error when i came across one of the old post regarding the same issue. The link for that post is:
    perfomance problem
    Actually i am getting an error when i run a procedure in Oracle 8i database. Error states:
    ORA-01562: failed to extend rollback segment number.....
    Now in the link i mentioned above there was a reply by JES. In the reply he recommend not to use commit after every delete in the loop. Instead use one commit after the loop. This decreased the number of commits from 175000 (5 * 35000) to 1.
    My questions is
    1) How would it reduce the number of comments?
    Can anyone explain to this point.

    sorry it should be commit rather than 'comment'
    Okay hoek i got the point but i m still confused. What my knowledge regarding rollback segment is that whenever we start a transaction using any DML a rollback segment starts to maintain unless we end the transaction using commit or rollback. So doing as
    LOOP
    DELETE.......
    DELETE......
    DELETE......
    END LOOP
    COMMIT
    will keep on increasing the size of the rollback segment. In other words rollback segment will have to keep the snapshot of all the three DML's in the loop till the commit.
    Instead if we do as
    LOOP
    DELETE.......
    COMMIT
    DELETE......
    COMMIT
    DELETE......
    COMMIT
    END LOOP
    will keep the size of the rollback segment less than the above example because we are commiting after every DML thus releasing the space before the start of the next DML.
    Don't you think the later can prevent us from ORA-01562 ?

  • Consolidator Exception: ORA-02291

    We have Olite 10g R2 on a Windows 2003 5.2 Operating system. We packaged an application and published it to the Mobile Server. When we attempt to assign access to a user or a group we are getting a VIRTUAL PATH IS NULL error. Even though we get this error it still shows the user or group as having access on the APPLICATION: ACCESS table. When we attempt to set the ROLES for the USER or GROUP we then get the following error.
    Error in executing “ Save application “:oracle.lite.web.resource.ResourceException: CONS-10049: Consolidator Exception: ORA-02291: integrity constraint (MOBILEADMIN.C$ALL_CLIENT_ITEMSFK) violated – parent key not found
    The 10.2.0.2.0 patchset has been applied. We are still getting both of these errors. Is there another patch that is required? Need some help.

    When you publish an application data is created in the mobileadmin repository schema
    C$ALL_PUBLICATIONS will contain one record for each publication item you create (plus a few pre-loaded default ones). The record includes the select statement used to define the snapshot for the publication item, so if this is for an object with a lot of columns or a complex select statement it can result in a large record. From this error is looks like the table space definition is too small.
    You need to talk to your DBAs about getting this increased. If it is too small as well as problems with the publish, the MGP process may fail as well as by default the CFM$ inqueue and CMP$ out queue tables also get created in this tablespace

  • ORA-1650: unable to extend rollback segment

    Hi,
    We have 20 RBS's and in our production instance we got very frequent alerts related to ORA-1650: unable to extend rollback segment continuously. When I looked for select STATUS from v$rollstat; I could see most of them are with FULL status. after couple of hours they disappeared and status became online.
    How to avoid these type of alerts?

    What version of Oracle?
    If you are 9ir2 or later, you should be going to automatic undo management. Though it won't help your 'we cannot add space' restriction. That's not an Oracle problem, that's a corporate issue.
    This problem may be caused by poor transaction design with too many processing doing too infrequent commits. That's not an Oracle problem either, that's a corporate/development issue.
    So...you don't have an Oracle problem.
    You can't stop the 1650s from occurring if you are unwilling to add space or address application issues. However, you can set up an email filter so that any emails containing ORA-01650 in the header or body get automatically sent to the trash.
    <sarcasm>
    If you can't solve a problem, then just ignore it!

  • How to solve about rollback segment fail to extend?

    I've a transaction about 50,000 records, then process fail in script. the error code is ORA-01562 FAIL TO EXTEND ROLLBACK SEGMENT = num. I'm use oracle database 7.3.4., form 4.5

    It would be better to have several small transactions instead of one huge transaction of 50000 records, like you say. You may use an additional log table to keep the log of how far you've got in processing those 50000 records, and pick up from where you've left in case something goes wrong.
    Anyway, one thing that may help would be to use:
    alter tablespace your_rbs_tablespace
    add datafile ...;
    to have more space for your rollback segment(s).
    Eventually, you may have a large rollback segment and set transaction use huge_rbs, in order to have your huge transaction use that huge rollback segment.

  • Olite10g - CONS-10049 / ORA-00972: identifier too long

    While trying to publish an application I get a "CONS-10049 / ORA-00972: identifier too long" error message for tables that have names of 26 or 27 characters long. It looks like it includes the owner/schema name to the length calculation and thinks the table name is exceeding 30 characters. If I remove the tables with these long names the app is built without an error. fyi - The table already exists in an O9iR2 database, I am simply trying to import it for this application.
    Any ideas?
    TIA,
    Scott

    Here's the answer:
    The max table name length limit is 30 characters. However, OLite prepends 4 characters to the name for an internally used publication item name (i.e. you might see something like clg$<table_name>). Therefore, the actual length limit is 26 characters, not 30. The solution would be to change the table name to be 26 characters or less, or if that is not possible, to create a view on the table and use that for your publication item.
