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,
TAB_GSHD.rowid hd_rid ,
JC1.rowid jc1_rid ,
JC2.rowid jc2_rid ,
YSHD_ID HXID,
JC1.JCDM QFD,
JC2.JCDM JLD
FROM
TAB_GSHX,
TAB_GSHD,
jCDM JC1,
JCDM JC2
WHERE
YSHD_ID=YSHX_ID
AND YSHD_QFD=JC1.JBJC_ID
AND YSHD_JLD=JC2.JBJC_ID
AND TO_CHAR(YSHX_time,'YYYYMMDD')='20030101'
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,

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.
ThanksAlso 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. -

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 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
MelHi Harry,
Have tried creating materialized view as follows...
create materialized view mac_dba.employee_mview
build immediate
refresh fast 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 mac_dba.employee@ORCL_2 e,
mac_dba.department@ORCL_2 d
where e.department_id = d.department_id
I get the following error message
ORA-12028: materialized view type is not supported by master site
thanks

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.This forum only is for questions relating to the use of OLAP Option. I would post your question on the database forum.

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.

Edited by: User71408 on Sep 5, 2008 12:38 AM9i 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.

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
REFRESH_FAST_PCT 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.
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_INSERT N F1 2077 Mv log is newer than last full refresh

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.
Cheers

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,

This procedure will refresh all of the MVs

To understand what's going on you should analyze the trace file that is generated when such an error occurs. Metalink note 131885.1 may be helpful.

How can i know that the material already deleted ?
Hello,
I'm new in SAP and need a help. In PP if an material is deleted or changed, it is marked as X in the xloek field of the RESB table. And when the order is TECO'd all the materials X'ed as weel. So how can i distinguish a deleted material in the order from the others? Please help.
Thanks in advance.
EmreHi,
I think I've found the answer and i want to share.
First i take the object number of the material from the RESB table with the objnr field.
Then look the JCDS table with that value. If an object exist with I0013 status and inact field
is not X, it is really deleted.
My query is
select single * from JCDS where objnr = resb-objnr
and stat = 'I0013'
and inact <> 'X'.
The statues can be seen the transaction bs22. -

Materialized view (fast refresh mode) + Materialized view log on another DB
Hi all,
I created a materizalied view using this script :
CREATE MATERIALIZED VIEW GIPS.DOSSIER_MEDICAL_MV2
TABLESPACE GIPS_T
NOCACHE
NOLOGGING
NOCOMPRESS
NOPARALLEL
BUILD IMMEDIATE
USING INDEX
TABLESPACE GIPS_I
+ REFRESH FAST ON DEMAND +
START WITH TO_DATE('11-janv.-2011 16:00:00','dd-mon-yyyy hh24:mi:ss')
NEXT sysdate (1/96)+
AS
SELECT N0_SEQ_BLOB_PDF,
EXAM_ID,
MPR,
RSM,
rub,
date_deb,
SPE,
commentaire,
SPR,
MEP,
MSJ,
TTD,
exam_type
FROM DOSSIER_MEDICAL@dbdoc_lk
WHERE DOSSIER_MEDICAL.EXAM_TYPE IN ('TELEM', 'SCANNER', 'EPPO_SECMED');
So you can see I'm using a dblink in the select statement ( DBDOC_LK )
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 can I restore to the Browser View of Book, several missing photo's?
Ten photos are missing from the Browser View of the Book. The photos show up in the Photo View and are checked as being used. They also show up in the working screen view of the book. All other photos in the book show up. Why are the 10 missing? How can I restore just those photos and not all photos for that book? What difference would it make in sending that book to the printer?

I'm not sure of your question
Are you saying that when you view the thumbnails of the book at the top or the screen that some pages do not show the photos even though they are in the book below?
If so that is a minor bug in iPhoto '09 - you can ignore it - it is just a display issue -- I forget exactly how but you can force a refresh of the book thumbnails - maybe double clicking on the book page - or maybe on the thumbnail
But in any case your book is fine (you should preview it before sending - http://support.apple.com/kb/HT1040 )

Audio disappearing in Adobe Premiere Pro CS6
So this is a weird one, but since I'm new to Premiere Pro maybe it'll be an easy fix? I imported several clips in the same batch that were recorded on the same camera with the same settings (same hour, even). I mark a clip in and out and drag it into
