Issue with complete refresh on materialized view when using rownum

Hi all,
I had an issue with rownum when using complete refresh
I am using rownum when creating materialized view and it is generation correctly.But the issue was when i am refreshing the same ,rownum was not getting sorted in ascending order.
anyone had come across this scenario

rownum is determined as the row is output, so "order by rownum" does literally nothing.

Issue with creation of a materialized view

Hi,
I have a SQL query that works fine.
But when I create a materialized view using the query, a few columns in the MV do not get populated at all.
What could be the issue here?

Update sequence wrong in Materialized view when using refresh group

Hi,
I made a trigger (for each row) on a materialized view(replication data from a master table in in a different database), which is refreshed by a refresh group (exec dbms_refresh.refresh('"...). However, the update order/sequence is important and must be handled (by the trigger) in the same order how the updates where done in the master table. Unfortunately the updates in the materialized view are NOT in the same order. The trigger is fired in a wrong order.
I am using database version 10.2.0
Does anybody reconize this problem, Is there a solution for this problem ( with keeping the refresh group mechanisme)?
Thanks
Regards

Graphic Styles - issue with creates style expanding to background when used

I have created a background style to use as a wire frame, and having created it, every time I use it the frame expands to the back ground size?

Thank you Peter and Amebr for your assistance. I ended up using RH Multilevel List Style, configured, and created an identical List Style in Word. I created a Single and a Multilevel (e.g., Level = bullet, Level 2 = squares); their challenge is matching RH indents with Word Indents... It's sort of a bear since RH does not have the Format Paragraph option (ref. drop-down) like Word Lists - Numbering functionality.
After generating my print document mu Bullet style reads "Normal (Web)"; even though the RH CSS Wizard recognized Word List Style I created (Ref. Font: Symbol, Font color: Black, Indent: Left: 0.15", Hanging: 0.25", Outline numbered + Level: 1 +, Numbering Style: Bullet + Aligned at: 0.15" + Indent at: 0.4", Priority: 100, Based on: No List.
Question: Would anyone out there know why is when I highlight my bullet list to verify the correct Style (with the Styles pane open) and I see the "Normal (Web)" [its Style type = Paragraph and Style based on = Normal) is selected? If it came through (from Rh) as a true Multilevel List Style, I should not see anything.
Happy Holidays!

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.

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
Edited by: 949697 on Mar 4, 2013 1:11 AM

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?

Is that expecte, any help would be appreciated.
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/

Problem with replication based on materialized view

Problem with replication based on materialized view...
Given:
1. Source: S-1
2. Targets: T-1, T-2
3. DB links: from T-1 to S-1, from T-2 to S-1
Required replicate table TBL on S-1 to T-1, T-2 via db links.
On S-1 was created materialized view log with PK on TBL. On T-1, T-2 were created mat.views as "on prebuilt table refresh fast on demand". In case of get "ORA-12034: materialized view log younger than last refresh" or initial load - perform complete refresh. Initial load on T-1 takes about 1 hour, on T-2 - about 12 hours. Refresh is executed via job with minutely interval. If refresh is running then it is not performed.
Problem: after initial load on T-1 performs fast refresh, but on T-2 raised ORA-12034 and complete performs again.
What's wrong?

34MCA2K2, Google lover?
I confess perhaps I gave a little info.
View log was created before MV.
It was the first initial load.
No refresh failed.
No DDL.
No purge log.
Not warehouse.
There is no such behavior for MVs on another sites.
P.S. I ask help someone who knows what's wrong or who faced with it or can me follow by usefull link.
P.P.S. It's a pity that there is no button "Useless answer"

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.

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.

Problem with property refresh in code view

I am suddenly noticing a problem in CS3 (v 9.0 build 3481),
OSX 10.4.11. In Code view (NOT Split view), any change to the code
causes the property inspector to display the message "You have made
changes to the code. To edit selection properties click refresh or
press F5".
It is my understanding that this feature is intended to
refresh the Design view when working in Split mode. I have not used
DW much in the last few weeks, but I never recall having this come
up before, and I work in code view quite a bit. Also, possibly
related, the tag selector strip at the bottom goes blank at the
same time the message appears in the property inspector.
This will be a significant impediment if it continues. Am I
crazy and it's always been this way, or is there a bug or setting
that I've inadvertently changed? I understand why refreshing is
necessary in Split view but I cannot see what purpose this could
possibly serve in Code view.

This is how it's always been for me with both DW 8 and DW CS3
for Windows. Can't say with regard to the Mac versions.

Refresh the main view when the pop up was closed

Hi,all
how can I refresh the main view when the pop up window was
closed to see the updated data? In pop up window I update
single row in the table based in main view.
Regards,
Michael

Michael,
There are 2 type of pop-ups in WD, and the answer is different depending on which type you are using:
1. Stand-alone browser window that hosts separate application (result of IWDWindowManager.createNonModalExternalWindow) -- no way.
2. Inner pop-up created via IWDWindowManager.createModalWindow -- absolutely possible:
-- a. Create event in component controller (probably with parameters)
-- b. Create method in component controller that fires this event (with corresponding parameters, if any)
-- c. In view that corresponds to window invoke method created in [ b ] and hence fire event. This should be done in action handler of something like "OK" Button or "Close" LinkToAction.
-- d. In any other controller subscribe to event described in [ a ]
