Materialized view logs pretty huge!

Hi,
I have a table MLOG$_XXXXX, which i guess is a materialized view log table. It is huge in size (80GB) and is growing at a very alarming rate.
Could someone please help me to reduce the size of this table?
How do I find out which materialized view is causing this table to grow? Is there any query through which I can find this out?
The database is of version 10204 and is running on HP Unix (B.11.11).
Thanks!

The materialized views in the database are:
SQL> select mview_name, owner, updatable, refresh_mode, last_refresh_date from dba_mviews;
MVIEW_NAME                     OWNER      U REFRESH_MODE    LAST_REFRESH_DATE
MV_EXCH_RT                     SYS        N COMMIT          03 JUN 2010 12:02:59
ADMIN_MGMT_CO                  JJORA      N DEMAND          06 JUL 2010 01:37:39

MV_JJGL_SUB_CD_141P            JJGL       N DEMAND          06 JUL 2010 01:24:43
7 rows selected.The table which grows at an alarming rate is:
SQL> select sum(bytes)/1024/1024/1024 from dba_segments where segment_name like 'MLOG$_XXXXX%';
SUM(BYTES)/1024/1024/1024
               77.8789063Now how do I find out, which materilized view is causing this table to grow? Can someone please provide me the query?
Thanks!

  • Materialized view logs issue

    We are having issues with the size of materialized view logs in one od the database. The size of the log table is around 32G. Will appreciate if somebody will help in explaining why it is having such a huge size and is not getting purged.
    At the same time the master table is having comparatively smaller size of 18G(did not check table fragmentation).
    Also, please help me in understanding what is required to be done for fixing this issue.

    Oracle automatically purges rows in the materialized view log when they are no longer needed. Because Oracle must wait for all dependent materialized views to refresh before purging rows from a materialized view log, unwanted situations can occur that cause a materialized view log to grow indefinitely when multiple materialized views are based on the same master table or master materialized view.
    For example, such situations can occur when more than one materialized view is based on a master table or master materialized view and one of the following conditions is true:
    Materialized view is not configured for automatic refreshes and has not been manually refreshed for a long time. OR
    Materialized view has an infrequent refresh interval, such as every year, etc
    You can also refresh the materialized views associated with the log so that Oracle can purge rows from the materialized view log.
    If a materialized view log needs to be purged manually for some reason a procedure called DBMS_MVEW.PURGE_LOG can be used.

  • Creating a Materialized View Log After the Data has been instered

    Hi,
    I am trying to create a method of replication from Oracle to MySQL using the Materialized View Log table.
    This has been done before and works quite well, the only problem is that I am trying to impliment the log after the table has been created and populated and wish to push all the existing data through the log file...
    Does anyone know if it is possible to refresh the Materialized View Log and not a Materialized View.
    The way the replication is intended to work is:
    Oracle> Data inserted into table
    Oracle> writes the vector data to the MVL
    Script> Monitors the MVL and can see the changes being made to the Oracle Table
    Script> Updates MySQL with the data and removes the rows from the MVL
    MySQL is then used with other unix systems
    Currently we export the data from the table using Triggers and a cronjob running every x minute to check for changes in the TriggerTables
    Many thanks for your time on this, I have been checking for almost a whole working day and not found the answer to this problem.

    Thats what I thought, the MVL will only read data that has changed since it was created and wont have the option to load in all the data as though it was made before the table was created.
    From what I have read, the MVL is quicker than a Trigger and I have some free code that prooved to work from a MVL using it as a reference to know what records to update. There is not that much to a MVL, a record ID and type of update, New, Update or Delete.
    I think what I will have to do is work on a the same principle for the MVL but use a Trigger as this way we can do a full reload if required at any point.
    Many thanks for your help.

  • Materialized view (fast refresh mode) + Materialized view log on another DB

    Hi all,

    So you can see I'm using a dblink in the select statement ( DBDOC_LK )

    CREATE MATERIALIZED VIEW LOG ON "DOSMED"."DOSSIER_MEDICAL"
    TABLESPACE "DOC_T"
    WITH PRIMARY KEY
    INCLUDING NEW VALUES;
    The problem is that my materialized view has never refreshed since its creation ! and I don't understand why ?
    Can someone help me ?
    Thank you.

    The REFRESH schedule causes a job to be created for the execution of the Refresh. You should see this job in DBA_JOBS / USER_JOBS.
    The job would run only if the instance parameter JOB_QUEUE_PROCESSES is set to 1 or higher (the default is 0). This parameter can be modified dynamically with an ALTER SYSTEM command.

  • How to CREATE MATERIALIZED VIEW LOG (MV fast refresh) with some JOINS

    Hi @ all,
    i'm trying to create a MATERIALIZED VIEW LOG for a fast refresh of a MATERIALIZED VIEW.
    It works fine with a simple Request in the MATERIALIZED VIEW:
    CREATE MATERIALIZED VIEW MV_ZOTD43_P
    TABLESPACE GDII
    BUILD IMMEDIATE
    REFRESH FORCE AS
    SELECT * FROM ZOTD43_P;
    COMMIT;
    CREATE MATERIALIZED VIEW LOG ON ZOTD43_P
    TABLESPACE "GDII"
    WITH PRIMARY KEY, ROWID, SEQUENCE INCLUDING NEW VALUES;
    call DBMS_MVIEW.REFRESH('MV_ZOTD43_P', 'f');
    But when I use a complex SQL-Request with some JOINS (one of the Table with spatial Data) in the MATERIALIZED VIEW, I get an error:
    CREATE MATERIALIZED VIEW MV_TEST
    TABLESPACE GDII
    BUILD IMMEDIATE
    REFRESH FORCE AS
    SELECT lptd04_p.sst_nr AS sst_nr,
    lptd03_p.aaaa AS aaaa,

    JOIN lptd03_p lptd03_p ON lptd03_p.lief_nr = lptd04_p.lief_nr;
    COMMIT;
    CREATE MATERIALIZED VIEW LOG ON LPTD04_P
    TABLESPACE "GDII"
    WITH PRIMARY KEY, ROWID, SEQUENCE INCLUDING NEW VALUES;
    call DBMS_MVIEW.REFRESH('MV_TEST', 'f');

    possible after a given set of changes, REFRESH FAST will

    Am I doing something wrong or is it not possible CREATE MATERIALIZED VIEW LOG when the MATERIALIZED VIEW got some JOINS?

  • Creation of Materialized view and Materialized view log.

    I wanted to create materialized view with 'REFRESH FAST ON COMMIT' option.
    1) Table1 --it is partitioned range + list -- Added primary key
    2) view1   -- having primary keys on view's base table
    Steps:
    1) create materialized view log on Table1 ; -- default primary key
    2) create materialized view log on view1.  --- It is giving below error.
    ORA-00942: table or view does not exist

    create materialized view
    REFRESH fast ON commit
    as
    select ...
    ... from table1
    where c1 in (select c1 from view1 where ... );
    Question:
    1) As i am getting above error while creating MV log on view. Can we create MV log on view or we have to create MV log on view base table?
    2) To create MV with ''REFRESH FAST ON COMMIT' option , do we need to have primary key on master tables? 
    Any pointers on this will really helpful.
    Thanks

    *Cause:    Either ROWIDs of certain tables were missing in the definition or
               the inner table of an outer join did not have UNIQUE constraints on
               join columns.
    *Action:   Specify the FORCE or COMPLETE option. If this error is got

    I have tested it and its working fine.A Strange error I am facing is, after an hour or so the materialised view gets corrupted and applicatin users gets an error saying error with the materialised view log.
    The log entry in the data dictionary gets deleted. Later I have to execute DROP on the log to completely remove it.
    I am confused how this can happen.

    How do i have a materialized with with a group by clause.

  • Can't update master table when creating a materialized view log.

    Hi all,
    I am facing a very strange issue when trying to update a table on which I have created a materialized view log (to enable downstream fast refresh of MV's). The database I am working on is 10.2.0.4. Here is my issue:
    1. I can successfully update (via merge) a dimension table, call it TABLEA, with 100k updates. However when I create a materialized view log on TABLEA the merge statement hangs (I killed the query after leaving it to run for 8 hrs!). TABLEA has 11m records and has a number of indexes (bitmaps and btree) and constraints on it.
    2. I then create a copy of TABLEA, call it TABLEB and re-created all the indexes and constraints that exist on TABLEA. I created a materialzied view log on TABLEB and ran the same update....the merge completed in under 5min!
    The only difference between TABLEA and TABLEB is that the dimension TABLEA is referenced by a number of FACT tables (by FKs on the FACTS) however this surely should not cause a problem. I don't understand why the merge on TABLEA is not completing...even though it works fine on its copy TABLEB? I have tried rebuilding the indexes on TABLEA but this did not work.
    Any help or ideas on this would be most appreciated.
    Kind Regards

  • ORA-12096: error in materialized view log

    Hi All,
    I had created a fast refresh materialized view. Log was also created.
    Now i dropped the mv and the logs.
    But now every time i update or insert into this customer table i get error message.
    ORA-12096: error in materialized view log on Customer
    ORA-00942: table or view does not exist
    There are entries in the DBA_MVIEW_LOGS for customer table.
    Please suggest.

    Hi,
    What database version are you on?
    And do you have access to Metalink/My Oracle Support?
    Found this, by the way:
    ORA-12096: error in materialized view log on <table>
    If problems occur when you try to access a log file for a materialized view, the system issues an ORA-12096 error message which is followed by the actual error. If the ORA-12096 error message is accompanied by an ORA-00942 message, the problem may be due to an online reorganization that was only partially undone. In this case, you can drop the log file for the materialized view manually (after you have verified that it is no longer required):
    DROP MATERIALIZED VIEW LOG ON <table>;
