Replication :: Materialized View - Refresh Group
Jan 6, 2010I am working on materialized view replication but i have an crucial issue. I have a refresh group which contain many MVs some are Read only and some are update but all are in Fast refresh mode (logs are created on both replication and MV sites on these objects) and are referentially integrated to each other i.e they have parent child relationship with each other as at replication site on base tables.
When refresh group job runs to refresh these MVs i got the errors
ORA-02292: integrity constraint (string.string) violated - child record found
After that job status has changed to break,but in the same time all the pending transactions at the MVs sites are pushed to Replication site i e ( Base tables at replication site and MVs of these tables are synchronized).In order to change the status of job to Normal, i have to disable some constraints(not all) on the MVs and manually run the job .After that job status will become Normal even i enable these constraints with validation.
What will be the reason ? Are there some MVs trying to complete refresh instead of Fast or increment refresh in this refresh group?If yes how i can trace out MVs and solve this problem?
Some other information ,

Application Express :: How To Automatically Send Report After It Is Created
Sep 16, 2013I am beginner . I found this tutorial how to save and access report.Storing and Accessing Reports in the Database In that tutorial report is saved onclick.Is there a way to automatically email report everytime report is generate or I should first save it (PDF, CSV,..) with SQL script and then email it? I also found that in Interactive report there is page process that can send e-mails. Is it possible that page process send e-mail with report or report should be also saved before sending? The reason for this is that we want to have a history of created reports.

Apr 6, 2012I was setting up disks groups and I accidentally created one group (DATA) with "NORMAL" redundancy but wanted it to be "EXTERNAL". I tried using asmca to remove disks from the group, drop the group, change the redundancy..... All of this failed because there was an spfile on the disk group.
I finally got it to work with using this procedure:
sqlplus '/ as sysasm'

drop diskgroup DATA
*
ERROR at line 1:
ORA-15039: diskgroup not dropped
ORA-15053: diskgroup "DATA" contains existing files

In summary, I am not sure why changing the redundancy would be so difficult if there is data on the disk group.
Trigger When View Created?
Aug 24, 2011I want to create a meta data table which has all the views users can access with a description of what the view was supposed to do.
Is there a trigger that can be created that fires when a view is created? To make it easy only one user in this system (oracle 9.2.0.8) has the create view privilege.
I know I could write a procedure to create views with dynamic sql that would do this but that seems a bit of overkill.
the sequence of events should go like this:
view created
trigger fires
record with view name and creation date inserted in a table
later, manually go to the table and add explanatory comment
or can I add a comment to a view like you can to tables?

View 5 Replies View RelatedReplication :: Materialized Views Refresh In Snapshot-group?
Mar 24, 2010How to refresh the dependent materialized views in a snapshot group. It refreshes in the order we add the materialized views to snapshot group?
Here below is the scenario.
MATVW_A
CREATE MATERIALIZED VIEW MATVW_A BUILD IMMEDIATE
REFRESH FAST ON COMMIT
AS SELECT * FROM EMP;
MATVW_B
CREATE MATERIALIZED VIEW MATVW_B BUILD IMMEDIATE
REFRESH FAST ON COMMIT
AS SELECT * FROM MATVW_A;
MATVW_C
CREATE MATERIALIZED VIEW MATVW_C BUILD IMMEDIATE
REFRESH FAST ON COMMIT
AS SELECT * FROM MATVW_B;
I created a snapshotgroup SNGRP with all the above materialized views.
DBMS_REFRESH.MAKE(name => 'SNGRP',
tab => 'MATVW_A,MATVW_B,MATVW_C',
next_date => TRUNC(sysdate) + 1,
interval => 'SYSDATE + 1');
The order of refreshing the materialized views would be like first materialized view MATVW_A should get refresh then after MATVW_B,MATVW_C.
As they are dependent views.Is there anyway where we can mention the order of refreshing materialized views in snapshot group.

New Tables And Indexes Created Not Show In Dba-segments View?
Aug 8, 2012I have created 3 tables and some indexes, but these objects do not show up in dba_segments view. Is this a normal behaviour? Previously, with dictionary managed tablespace, I can specify the minimum extent to create, when the table/index is created. But I'm not sure how the locally managed tablespace work.
I'm using Oracle 11g R2 (11.2.0.1.0) for Microsoft Windows (x64), running on Windows 7.For the purpose of reproducing this issue, I have created the tablespaces as follow:
CREATE TABLESPACE CUST_DATA

Replication :: Setup A Refresh Group For Nested Materialized Views
Mar 25, 2009Suppose I have materialized view A,B,C. Now I have a new materialized view D which is created from A,B,C. Can I put D into same refresh group?
I am not sure whether D will be refreshed first before A,B,C, resulting that D do not get any update If that is the case, the result will be wrong
If we cannot use refresh group to update nested materialized view, what should we do?

SQL & PL/SQL :: How Query Call Embedded Materialized View Automatically
Jul 13, 2010I have to optimize the queries for user online panel. We have already created 2 materialized views:
mv_channel, mv_area
mv_channel (article_id, area, aweg_txt3, sum(value), sum(units))
mv_area (article_id, area, sum(value), sum(units))
For this query:
SELECT /*+ REWRITE*/
sum(value) as value,
sum(units) as unit,
article_id
from
...
where
...
and area in ('RB','RR','RS')
and aweg_txt3 n ('SB')
...
is the matview mv_channel very useful. The execution time was just 8s-13s instead fo 190s. But if the user also asks for this query but without AWEG_TXT3 in the where-clause, then it lasted 1:25min (longer than if the matview mv_area will be used).
The problem is that, the matview mv_area cannot be used in the case, in which the AWEG_TXT3 is in where clause (because it doesn't have aweg_txt3).
How can i do, so that :
- in case of AWEG_TXT3 in where-clause the matview mv_channel will be used and
- in another one (without AWEG_TXT3 in where-clause) the matview mv_area will be called automatically from the query

Materialized View Refresh Between 2 Database?
Jul 12, 2012DB_VERSION=10.2.0.4
OS_VERSION=Windows 2008 R2
RAM_SIZE=32 GB
We have 2 production (OLTP) database( DB1 (18GB) and DB2 (200GB) ) on a server out of which DB2 database has almost 20 Materalized Views all (REFRESH FORCE ..ON DEMAND).
I have already informed the client that this is not the OLAP database where you are going to make use of the M Views for reporting purpose. However currently the client does not have any alternative.
Breif details :-
Out of 20 M Views 3 refresh once a week and where as the rest refresh every night daily.
We are currently testing a new website for which we had to re-schedule all M Views from their Old timings to New Timings i.e. Daily Basis.
But post re-scheduling the database performance was badly degarded as the database was too slow also the number of archives increasted to 300GB which was earlier 100 GB.To resolve the issue , we had to go back to the old timings and the database is currently working fine.
Requirement :-Client is looking out for an alternative solution as he needs to once again change the M View refresh time i.e. Daily Refresh.We already have 2 Oracle Instance on the server
Questions :-
1. Can i create another database ( sayTESTDB2 ) in no archivelog mode and create a db link to reduce the load on the server ?
2. If Yes .. Then is there any relavent link /example or Metalink Note ID for the same??
3. What all parameters do i need to consider while creating a DB Link ?
3. Out of 32 GB RAM , I have given 4GB and 8GB sga_max to DB1 and DB2 Respectively . Also the cpu utilization is normally 50-%60%.
Since currently we do not have any Licence for other server .. Can i make use of the same server ( i.e. creating 3 rd Oracle Instance )?
Since the main intention of this activity is reduce the load from the DB2 onto TESTDB when the daily refresh has set once again

As of now, I could understand we can do "start with" and "next" option which will schedule refresh with same interval but not with different time interval which I mentioned above.
