Erro perforing Fast Refresh of Materialized View.

Hi Experts,
We are facing serious problem while refreshing materialized views using fast refresh option in ORACLE..
For the very first time we are performing Complete refresh of data from DB1 to DB2 for few tables.Ongoing we are performing Fast Refresh.
Sometimes the fast refresh works fine without any error and sometimes it fails with the below error.
ERROR at line 1:
ORA-32320: REFRESH FAST of "CIR"."C_BO_COMM" unsupported after cointainer table
PMOPs
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 803
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 860
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 841
ORA-06512: at line 1we came to know the folowing.
// *Cause:
  A Partition Maintenance Operation (PMOP) has been performed on the materialized view,
  and no materialized view supportsfast refersh after container table PMOPs.
// *Action:
               Use REFRESH COMPLETE.
     Note: 
               you can determine why your materialized view does not support fast refresh after PMOPs using
               the DBMS_MVIEW.EXPLAIN_MVIEW() API.Please let u know what action to be taken to avoid this.
Please note that this error is not repeated always. Some times REFRESH FAST is happening and some times it is throwing error.
Appreicate your earliest reply.
Thank you.

9i doesn't support fast refresh after truncate. Read the metalink note 275325.1
You should be sure no truncate has been executed, or use complete refresh.

  • Problem in fast refreshing nested materialized views

    Hi all,
    While developing an ODS(Operational Data Store) system, i've created base materialized views from production database to ODS database which would use fast refresh. Now, i need to create nested Materialized views on these base MViews which contains joins and aggregations which should refresh on FAST mechanism.
    But while doing so, got several problems though Nested materialized views can be built using Complete Mechanism. The reporting queries is important and we want it should not hit the production database, rather it should hit the ODS db. But we are failing to build the Nested Materialized views which works on FAST.
    I tried google, oracle docs but all in vain. i tried to do a simple testing which also failed. I would be grateful if anyone can help in in this regard. I'm attaching the test case experimented,

    Problem in fast refreshing nested materialized views

  • How can I fast refresh the  materialized view !!

    I created a MV base on some tables in order to improve the querey speed.
    but the mv I have created falied to refresh fast.
    because there are two same table in the from clause:
    jcdm jc1,jcdm jc2
    create materialized view temp_mv
    nologging
    pctfree 0
    storage (initial 2048k next 2048k pctincrease 0)
    parallel
    build immediate
    refresh force
    on demand
    as
    select
    TAB_GSHX.rowid hx_rid,

    the column msgtxt of the table MV_CAPABILITIES_TABLE is :
    "the multiple instances of the same table or view" and " one or more joins present in mv".
    How can I succeed in fast refresh the above temp_mv!!!
    thanks.

    lianjun,
    When you are using Oracle9i there is a procedure which can help you setup the materialized view. If some option isn't working it gives you hint why it doesn't work.
    The procedure is dbms_mview.explain_mview.
    Take a look at the documentation how to use it. (In the Oracle9i DWH guide the package is explained.)
    Hope this helps
    With kind regards,
    Bas Roelands

  • Fast refresh of materialized view

    Hi All,
    This is my first posting on this forum, so I hope I don't step on anyone's toes as I wade into a problem that I am experiencing.
    I have a number of either join-only or single table aggregate materialized views that I have experienced problems with. All the views are setup for FAST REFRESH ON DEMAND but I'm hitting an error if I execute a COMPLETE refresh of the view when I've done an ALTER SESSION ENABLE PARALLEL DML. The error I get is:
    ERROR at line 1:
    ORA-30439: refresh of 'DTKTGT.CTNS_PER_HR_VOL_AGG_MV' failed because of ORA-32320: REFRESH FAST of "DTKTGT"."CTNS_PER_HR_VOL_AGG_MV" unsupported after cointainer table PMOPs
    ORA-06512: at "SYS.DBMS_SNAPSHOT", line 814
    ORA-06512: at "SYS.DBMS_SNAPSHOT", line 872
    ORA-06512: at "SYS.DBMS_SNAPSHOT", line 852
    ORA-06512: at "DTKTGT.MV_REFRESH", line 21
    ORA-06512: at line 2
    Any help anyone could provide would be greatly appreciated as every now and then, a COMPLETE refresh is unavoidable and using the ENABLE PARALLEL DML makes the refresh run a lot faster than without the ALTER SESSION.

    Thanks,

    ORA-12004: REFRESH FAST cannot be used for materialized view "string"."string"
    Cause:      The materialized view log does not exist or cannot be used. PCT refresh is also not enabled on the materialized view
    Action:      Use just REFRESH, which will reinstantiate the entire table. If a materialized view log exists and the form of the materialized view allows the use of a materialized view log or PCT refresh is possible after a given set of changes, REFRESH FAST will be available starting the next time the materialized view is refreshed.http://ora-12004.ora-code.com/

    Actually you can get Oracle to tell you why the view does not have the capabilities you want using the DBMS_MVIEW package. For example you could have done something like this...

  • Fast refresh of materialized view on remote database

    Hi All,
    I have the following scenario, two databases called ORCL_1 and ORCL_2
    ORCL_1 (11.1.0.7) ORCL_2 (10.2.0.1)
    EMPLOYEE (Master table)
    DEPARTMENT (Master table)
    I have created materialied view logs on both the master tables as follows...
    create materialized view log on department
    with rowid, sequence(department_id, department_name)
    including new values
    create materialized view log on employee
    with rowid, sequence (employee_no, surname, firstname, title, department_id, dob, dependants)
    including new values
    On ORCL_1 i have created a materialized view as follows...
    create materialized view employee_mview
    build immediate
    refresh on demand with rowid
    as select e.employee_no, e.title, e.firstname, e.surname, d.department_name, d.department_id, e.dob, e.dependants, e.rowid emp_rowid, d.rowid dept_rowid
    from employee@ORCL_2 e,
    department@ORCL_2 d
    where e.department_id = d.department_id
    then i have a scheduled task, on ORCL_1, that execute "...dbms_mview.refresh ('mac_dba.employee_mview','?');...." every minute
    this works fine, except for the fact that all the records are deleted from the materialized view and then all the records are re-inserted.
    How can i get it so that only the records that have been added or amended, as per the materialized view logs, are refreshed to the materialized view.
    thanks
    Mel

  • Fast refresh of "materialized view with joins only"

    Hi,
    My Requirement:
    I need to create a materialized view joining two tables.
    Table1 -> Does not have primary key
    Table2 -> Has a primary key
    I need to refesh the mat view only when DML commands are done on Table1 alone.
    And it will be better if i have a Refresh on commit rather on demand.
    The following code is what i used and it dint work for me:
    CREATE MATERIALIZED VIEW LOG ON Table1 WITH ROWID;
    CREATE MATERIALIZED VIEW LOG ON Table2;
    CREATE MATERIALIZED VIEW AAYT_ETF
    REFRESH FORCE ON COMMIT
    ENABLE QUERY REWRITE
    AS
    SELECT A.rowid "table1_rowid", A.ACCTNUM, A.CORR_NUM, A.OFC_NUM, A.RR_NUM, A.BUY_SELL_CDE, A.ACT_AMT, A.CSP_SYM, A.SECR_DESC, A.ACT_QTY
    FROM Table1 A, Table2 G WHERE
    A.CSP_NUM = G.CSP_NUM AND
    G.ASST_SUB_STYP = 'ETF';
    Issue Faced: In this case the refresh happends even while i do DML on Table2.
    But i need the refresh only when i do DML on Table1. I also unable to create Refresh Fast Mat view.
    Can anyone please tell me how to create the Materialized view Log and the Materialized view. Thanks in advance.

    On the DB referenced by this dblink, I created a materialized view log using this script :
    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 speed up fast refresh of materialized view without primary key

    Thought I'd share this info, as I couldn't find anything on here to help me diagnose the issue:
    I had a materialized view that was taking longer to perform a fast refresh than it took to perform a complete refresh. My mview had no primary key, as the base table had no primary key.
    I created a trace file for the session and saw references to a column M_ROW$$ in my mview. Nowhere in the data dictionary could I find a reference to the m_row$$ column in my mview, but apparently it exists and is created automatically. After creating the index below, the fast refresh took 6 minutes to add 500k rows to the materialized view. (versus 4+ hours without the index) When I looked in the trace file, I noticed that for each row in the mview log, it first tries to update the mview with an UPDATE statement, then it performs an insert of the new data. Seems like it should be able to determine whether to perform an update or insert based on the DMLTYPE$$ column of the mview log. What was killing my performance was the UPDATE phase. Since I had no primary key on the mview, and no index on the m_row$$ column, the UPDATE phase was performing a full table scan of my mview for every row in the mview log. I was expecting it to be smart enough to only perform inserts, as the only transactions against the base table were inserts.
    In summary: If you have a materialized view without a primary key, create an index on the m_row$$ column of the mview, even though no such column displays in the data dictionary.
    ex:
    CREATE MATERIALIZED VIEW mv_minidrr ...
    CREATE INDEX pk_mv_minidrr ON mv_minidrr(m_row$$) ...

    Well, there indeed is a column called M_ROW$$
    Your MLOG$_EMP is nothing but the materialized view log on the base table.
    SQL> create  materialized view log on emp with rowid ;
    Materialized view log created.
    SQL> create materialized view emp_mview refresh fast on demand with rowid as select * from emp ;
    Materialized view created.
    SQL> desc mlog$_emp
    Name                                                  Null?    Type
    M_ROW$$                                                        VARCHAR2(255)
    SNAPTIME$$                                                     DATE
    DMLTYPE$$                                                      VARCHAR2(1)
    OLD_NEW$$                                                      VARCHAR2(1)
    CHANGE_VECTOR$$                                                RAW(255)
    SQL> select table_name, column_name from user_tab_columns where column_name = 'M_ROW$$' ;
    TABLE_NAME                     COLUMN_NAME
    MLOG$_EMP                      M_ROW$$
    1 row selected.

  • Fast Refresh in Materialized Views Partitioned

    Hi all.. I've a little problem... let's go into it:
    I have two tables:
    A dimension table , named D1
    A partitioned fact table, named F1
    I create two materialized views log in each of 2 tables.
    Ok.. Now, I created a Materialized View Partitioned, name MV_F1D1, with incremental refresh for it...
    I can create the Materialized View Partitioned with fast refresh, no problem here...
    First time Oracle make a Complete refresh, everything ok.. Then I make a
         BEGIN
              DBMS_SNAPSHOT.REFRESH('MV_F1D1','F');
         END;
    And everything goes well...
    But.. In my fact tables, I load the data with a temporary table, named F1_NP (Fact table no partitionated)
    with the data of the current month. Every week I do this:
    1) Load the data in F1_NP
    2) If the LAST_PARTITION_MM_YYYY not exists in F1, I add the partition to F1...
    3) ALTER TABLE F1 EXCHANGE PARTITION LAST_PARTITION_MM_YYYY WITH TABLE F1_NP
    And, this is the problem....
    After that process, the Log table of F1 is empty..
    When i'm trying to fast refresh the mv_F1D1, I got an error
         ORA-12097 changes in the master tables during refresh, try refresh:
    THis occurs when only I truncate a partition
    in the fact table too.
    Ok.. My only solution here is to make a complete refresh.. But I have only a new partition. I expected that with the PCT, Oracle let me
    do it a fast refresh.      
    I'm looking for a solution in the web, and I installed the utlxmnv.sql:
    1) Before add a partition in F1
    truncate table mv_capabilities_table;
    exec DBMS_MVIEW.EXPLAIN_MVIEW ( 'MV_F1D1' );
    select * from mv_capabilities_table;
    PCT Y
    REFRESH_COMPLETE Y
    REFRESH_FAST Y
    REWRITE Y
    PCT_TABLE Y F1
    PCT_TABLE N D1 2068 Relation is not partitioned.
    REFRESH_FAST_AFTER_INSERT Y
    REFRESH_FAST_AFTER_ONETAB_DML Y
    REFRESH_FAST_AFTER_ANY_DML Y

    REWRITE_GENERAL Y
    REWRITE_PCT Y
    PCT_TABLE_REWRITE Y F1
    PCT_TABLE_REWRITE N D1 2068 Relation is not partitioned.
    2) After truncate a partition in F1
    truncate table mv_capabilities_table;
    exec DBMS_MVIEW.EXPLAIN_MVIEW ( 'MV_F1D1');
    select * from mv_capabilities_table;
    PCT Y
    REFRESH_COMPLETE Y
    REFRESH_FAST Y
    REWRITE Y
    PCT_TABLE Y F1
    PCT_TABLE N D1 2068 Relation is not partitioned.

    REFRESH_FAST_AFTER_ANY_DML N F1 2076
    REFRESH_FAST_AFTER_ANY_DML N 2161
    REFRESH_FAST_PCT Y
    REWRITE_FULL_TEXT_MATCH Y
    REWRITE_PARTIAL_TEXT_MATCH Y
    REWRITE_GENERAL Y
    REWRITE_PCT Y
    PCT_TABLE_REWRITE Y F1
    PCT_TABLE_REWRITE N D1 2068 Relation is not partitioned.
    BEGIN
              DBMS_SNAPSHOT.REFRESH('MV_F1D1','F');
    END;
    ORA-32313: REFRESH FAST of "MV_F1D1" unsupported after PMOPs
    any ideas? Can I fast refresh a MV partitioned (composed with a Table Dimension and Fact table)
    with PCT when I add data in the Dimension Table/add a partition in a Fact Table Partitioned?

    Look at ATOMIC_REFRESH option, if you set this to FALSE you may see performance gain as it'll use DIRECT PATH and TRUNCATE. Data will be unavailable while being refreshed though.

  • How can I manually refresh a Materialized View

    Hi,
    There's a materialized view created in 2006 as under:
    CREATE MATERIALIZED VIEW "schema"."mv_name"
    USING INDEX
    REFRESH FAST ON DEMAND
    WITH PRIMARY KEY USING DEFAULT LOCAL ROLLBACK SEGMENT
    DISABLE QUERY REWRITE AS SELECT * FROM "table_name@dblink;
    The problem is that the last refresh was done in Aug. I want to manually refresh this materialized view right now as there is a procedure based on this MV and its not showing the right data as the above materialized view has not been refreshed, so the data for this month is not showing.
    Please let me know how I can refresh that MV right now.
    Also do I need to change the refresh option. How can I change it so that the MV refreshes itself every second.
    Thanks

    Also do I need to change the refresh option. How can
    I change it so that the MV refreshes itself every
    second. Every second? Why do you want to do that?? Perhaps waht you really want is refresh the MV on commit.

  • Refresh of materialized views

    Hi there,
    i've got a question to the refreshment of materialized views: when updating or inserting / deleting data of some specific tables, my materialized view should be updated.
    First of all, i though to make that happen by using triggers on the specific table and the DBMS_MVIEW.REFRESH() mechanism. But as i have read pretty often, it isn't recommended doing that with triggers.
    But how can I get what I want :-)
    Thank a lot for your answers,
    Martin

    Thanks for your answers,
    the case with FAST REFRESH doesn't work. Our materialized are very complex and are using e.g subselect-statments, analytic functions,UNION, Order, Group by.... According to the documentation, we can't use the FAST REFRESH.
    Using the REFRESH ON COMMIT could be possible. Having a look at the documentation, there is one interesting sentence: A REFRESH ON COMMIT materialized view is refreshed automatically when a transaction that does DML to one of the materialized view's detail tables commits
    What are the materialized view's detail tables? Are that all tables in the FROM-Part of the query?

    Best regards,

    It may be a bug, or it may be a result of the dependencies between the materialized views. I don't have a 9.2.0.6 instance that I'm willing to trash to test this, but this is what I get on 9.2.0.1.
    If it is a bug they at least changed the behaviour of the bug in 9.2.0.6.
    I ran your script up to the first commit then did:
    SQL> SELECT * FROM t;

    SQL> EXEC DBMS_MVIEW.REFRESH('V_MV');
    PL/SQL procedure successfully completed.
    SQL> SELECT * FROM v_mv;
    no rows selectedNow, this is confusing, so:

    1 row created.
    SQL> insert into v (id, t_id, v_name) values (6, 6, 'V_B_2');

    AAAH4dAAIAAAAl1AAE AAAH4ZAAIAAAAlFAAB V_B_2               5Forcing the refresh on v_mv gets:

    Then, I blew everything away and did it allagain up to an including the inserts into t, then I inserted into v and commited. Now, both MV's were correct, so I did:
    SQL> insert into t (id, t_name, t_date) values (6, 'A', sysdate);
    1 row created.
    SQL> insert into v (id, t_id, v_name) values (6, 6, 'V_B_2');

    1 row created.
    SQL> commit;

    I may play with this some more, it seems truly strange to me.
