Sep 11, 2013I have 5 MViews that I want to refresh in two occassions, every sundays and at the 1st of the month. I created a Refresh Group for the weekly and that work fine. But when I tried to created the second Refresh Group for the monthly I get a "materialized view is already in a refresh group".

PL/SQL :: Getting Rate For Report?
Nov 8, 2012 This is my sample code:
create table myReport(
report_id integer,
product_class_id integer,
place_id integer,
[code]...
would like to get the rate for my report table base. The search for the rate first will be base on product_class_id, year and place_id, second if the report row match the product_class_id and year but not place_id it should get the default rate (in my rate table the place_id is null).
Last if the report row doesn't match any key the result should be zero.This is my result query, how can I do this query?
report_id product_class_id place_id fy rate
1 1 1 2012 15
2 1 2 2011 6
3 1 3 2011 7
4 2 2 2012 18
5 2 5 2011 2

7 4 1 2012 0

How To Calculate Redo Rate
Nov 14, 2006how would I be able to calculate the Redo rate for using in the Required bandwidth Formula as seen below :
Required bandwidth Formula ((Redo rate in bytes per second / 0.7) * 8) / 1,000,000 = bandwidth in Mbps
Example: 385 KB/sec peak rate would require an available network bandwidth of at least
((394253 / 0.7) * 8) / 1,000,000 = 4.5 Mbps.

Replication :: Cannot Fast Refresh Truncated MV Even After Complete Refresh
Aug 14, 2010I am getting ORA -32320 when I tried to fast fresh MVs that were truncated.I am able to complete refresh all MVs. However, some MVs are still giving me ORA-32320 when I try to do fast refresh even after complete refresh.
DBMS_MVIEW.EXPLAIN_PLAN says the MVIEW can be fast refreshed.
ERROR at line 1:

how to again make the MVs fast refreshable?

Performance Tuning :: MVIEW Huge Temp Space?
Nov 23, 2011I run a query, takes 20 minutes or so, I traced it and can see no more then 20-30 mb of temp space required in the plan.
I developed it for use in a materialized view, however when I create the mview with the sql, the temp space required grows until it maxxes out. I increased the existing 10gb to 50gb but still maxxed out. Took the SQL out, reran it, ran in 20 minutes barely scratching the temp, I ran a "create table as <select>" and same behaviour as the SQL, barely touched the temp as per the plan. So the temp space blolwing is unique to the mview create.
Im working with mviews years on several sites and have never seen this.
SQL & PL/SQL :: PCT Is Not Enabled While Creating Mview / Though Base Tables Are Partitioned

enable query rewrite as
[code]....
If i remove the sub query and create the mview like this,then PCT is enabled.
create materialized view MV_summary_SEC
refresh fast
start with sysdate
nEXT SYSDATE + 1/24
enable query rewrite as
select PERIOD , SUM(SUM_WEB_HITS)
from summary ,date_table
where PERIOD >= DATE_TABLE.CUR_DATE
group by PERIOD
Is it simply because oracle doesn't support PCT if the definition contains subqueries ?
SQL & PL/SQL :: Possible To Hold Data From Select Statement Without Temp Table Or MView?

because my DBA does not give access to create temp table.but we are selecting the records from 3 different sql statement.
Example: inserting in temp table
a) insert into temp select empno,ename,sal from emp where sal>4000
b) insert into temp select empno,ename,sal from emp where dept=40
c) insert into temp select empno,ename,sal from emp where comm is null

MV-Scheduled Refresh Failure?
Jul 12, 2012I have created a materialized view log on table testing_mview_rev in 11g:

And a MV on it in 10g:
SQL> create materialized view testing_mview_1_rev REFRESH Force start with (sysdate) next (sysdate+1/1440) with rowid as select * from testing_mview_rev@S58_TO_S56;

Now this is suppose to automatically refresh itself every minute but refresh is failing. However manual refresh is working fine.
what I have missed here. is there any other way to schedule the MV to run every minute?
