I 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".
You can only have a materialized view in one refresh group? What options to I have to refresh it in different intervals?
My MVIEW has a refresh rate (sysdate + 1 ) + 24/24 So how often it gets refreshed .
View 3 Replies View Relatedhw can i check the refresh rate of existing Mview..

it creates a DBMS_JOB for me with the required interval.
But now my requirement is that I want to create a job on the existing MV.
Now I tried the code mentioned in the previous post to schedule the job.
This job does not work. When I tried to execute it manually using:
DBMS_IJOB.RUN(12345) as sys user is throws the follwing error.

How to reset the status of Refresh Group?
In our database, it is showing the status of Refresh group to 'Broken'.
I 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 ,
Replication site running with 10gR2 Enterprise Edition.
Materialized View site running with 10gR2 Slandered Edition.
How 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.
Suppose 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?
tell me if a REFRESH GROUP is automatically created when a materialized view is created?
View 3 Replies View RelatedI 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.

We have created this Mview in two schemas i.e.MRD and MRDSEIn MRD schema we are getting the date format is MM/DD/YYYY where as in MRDSE we are getting the format DD-MON-YYYY. why we are getting the difference in date format in two schemas.We are not modifying any thing.

I 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.
I created a mv for one of the partitioned tables but on viewing the mv capabilities it still shows PCT is set to 'N'.

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 ?
Is it possible to hold the data from select statement without temp table or materialized view or view in oracle?
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
I have create a mview using a dblink with the refresh difference of every 10min. Suddenly I check the mview refresh date and time it was not getting refreshed automatically at the time interval specified.

I am trying to find out what is the cause of not refreshing and also googled for the same. got some link also either not linked to same problem or not cleared.. Where should i checked regarding the error cause.
I'm trying to group sets of data based on time separations between records and then count how many records are in each group.
In the example below, I want to return the count for each group of data, so Group 1=5, Group 2=5 and Group 3=5
SELECT AREA_ID AS "AREA ID",
LOC_ID AS "LOCATION ID",
TEST_DATE AS "DATE",
TEST_TIME AS "TIME"
FROM MON_TEST_MASTER
WHERE AREA_ID =89
AND LOC_ID ='3015'
AND TEST_DATE ='10/19/1994';
[code]....
Group 1 = 8:00:22 to 8:41:22
Group 2 = 11:35:47 to 11:35:47
Group 3 = 15:13:46 to 15:13:46
Keep in mind the times will always change, and sometime go over the one hour mark, but no group will have more then a one hour separation between records.
I read that rownum is applied after the selection is made and before "order by". So, in order to get the sum of salaries for all employees in all departments with a row number starting from 1, i wrote :
select ROWNUM,department_id,sum(salary) from employees group by department_id
If i remove rownum, it gives the correct output. Why can't rownum be used here ?
Refer to the txt file to create table and insert data.
I executed the following query-
SELECT priority, detail, COUNT(1) FROM TEST GROUP BY priority, detail
and got the following result-
PRIORITYDETAIL COUNT(1)
StandardPatch 27
StandardInitial TSS 1
StandardInitial development 10
StandardProduction deployment5
High PriorPatch 1
Now I want that Initial TSS and Initial development should be combined as Initial together and I should get the result as follows:
PRIORITYDETAIL COUNT(1)
StandardPatch 27
StandardInitial 11
StandardProduction deployment5
High PriorPatch 1
Is there any way to add one disk group space to another disk group. Because One of my disk group is full i want to add space in to that group.
View 1 Replies View RelatedI'm using this code, and it performs fine, but I'm wondering if there is a more elegant way to do it--maybe with "ROLLBACK". Basically (as you can see) I need to get a normal count for each group but also for each group take a percentage of the total count (so all groups pct adds up to 100 (oh yeah, don't test for zero below, but just a test... )

How can we refresh a database ?
View 3 Replies View RelatedI have a created a materialized view which is based on a view on remote database. Now how do I refresh the view.
Materialized view is created by
CREATE MATERIALIZED VIEW mv_employee_name
AS SELECT EMPLID, EMPL_NAME
FROM VEMPDATA@REMOTEDB
WHERE REGION = 'US';
how the refersh happens or how do I specify the refresh clause.
REFRESH FAST option is looking for VIEW LOG on the master table but in this case its a remote view, so I cannot create any object on remote db.
A scheduler job is there to refresh some materialized views. All the views are run under single job name. Some mviews are not refreshing and those are not refreshing in the next run too.if we run those mviews manually then they are working fine from then . after some days those views which i told before are not refreshing and this happens frequently and i check the job_run_details views also and i am not seeing any errors in that.
