Hi I have a problem with refreshing of Mviews , I will narrate every
thing step by step:
1.create table a (a number);
2.insert into table a values(&a); (after inserting 2 rows and
commiting)
3. create MATERIALIZED view b REFRESH WITH ROWID START WITH SYSDATE
NEXT sysdate + 2/1440 as select * from a;
Mview created
4. insert into a values(&a); 9after inserting 2 more rows and
commiting)
5.select * from a;
4 rows selected
6. select * from b;
2 rows selected (BUT HERE IT SHOULD BE 4 ROWS)( EVEN WAITING FOR
10 MIN , NOTHING IS COMING)
WHATS GOING ON..
if i do the same on diffrent server it works, but not here..
then i thought checking some parameters
the parameters i checked with values are :
query_rewrite_e nabled boolean TRUE
query_rewrite_i ntegrity string ENFORCED
i guess both are fine,
now iam not looking to go for fast refreshes and rightnow iam using
" EXEC DBMS_MVIEWS.REF RESH('B')" to refresh it..
Can u please help me out, what Iam doing wrong..
It would be great if u mail me also on my personal mail id kh************* @rediffmail.com too , Thanks alot in advance,

Regards, Frank van Bortel
Hey Thanks alot Frank,
It really worked, and for me an addition in my DBA knowledge..:-)
I guess the culprit was job_queue_proce sses as 1st i putted the
nls_date_format and checked it 1ce ..it didn't worked then i putted
the parameter to 3 and it worked ..like a charm...
thanks 1ce again,
Takecare ,
Prashant.

Do not trust values returned by materialized views under SQL Server

I already posted this message under microsoft.public.sqlserver.server

we can fail our materialized view that performs a count_big on those

I first created a materialized view that was based on the org striped views like po_headers hence the automatic refresh was not happening.
After automatic complete refresh, the materialized view was showing null records.
Hence I based the materialized view on "_all" tables and then based a view on this materialized view and this view I made org striped.
In the materialized view , I was refering to...

Hi All,
Sorry this may be a repost as first attempt died on me...
I have a set of 50 materialized views that are populated every morning.
However 2 of the materialized views contain no records (I know the master
does contain records).
None of the jobs are broken and all run as scheduled.

Hi All,
I need to know the best way to set up a datawarehouse/materialized

are getting too complicated to crunch in real time.
Should I use a make-table I run after each update?
Thanks,

I have a query thats taking long time to execute. So i have created a Materialized view to refresh it every hour. But when the Materialized view is being refreshed, there is no data in the Materialized view table. I think it truncates the table before every refresh.
Is there any way to keep the old data while its being refreshed.?
