There is a materialized view:

REFRESH FORCE
START WITH SYSDATE NEXT SYSDATE + 5/24/60
AS
SELECT F1,
F2,

DROP TYPE MY_MAT_VIEW_row_type;
CREATE TYPE MY_MAT_VIEW_row_type AS OBJECT
(
F1 number,
F2 varchar2(100),
F3 date

I've noticed that when materialized view is near to be refreshed (every 5 minutes) there is some "delay" in getting result sets using this query:
SELECT *
FROM TABLE(FN_GET_MY_MAT_VIEW(100)) a;
And when the refresh is finished the result set returns immediately.
Question.
Is there a way to avoid such "delay" while materialized view is refreshing?

Creating Materialized View On Remote Simple View
Dec 11, 2012I'm trying to create a Materialized View on a remote database from a simple view. The reason is, the data owners don't want to grant explicit tables privileges to external subscribers.
A new schema is created to publish data in the form of a view. I've created mlogs on the master tables, and granted them to the subscriber, but it's still complaining about a missing primary key on the view. A primary key does exist in the master table.
Is there another work around for this situation without having to work inside the data sources' environment?

Apr 25, 2012We wrote one data load process to load GZ files into Database.during process we will change client facing view definitions to backup table so that we can work on base tables.
This view definition changes are related to FROM and WHERE clause (not columns/type). during load process, client/user may connect to current server and accessing these views. My question is what will be the reflection of changing view definition while user is accessing view?
I created a scenario-
STEP1: Created a view-
create or replace view view_01 as
select object_name from dba_objects union all
select object_name from dba_objects union all
select object_name from dba_objects union all
[code]....
View definition is replaced by new definition while select is executing on that view. select returned number of records as per view definition one.

Replication :: Can Nested Materialized View Use Pivot Function
May 17, 2012I have a question about nested materialized view.
Firstly, I have created 3 mv log on 3 table(target,target extension,brand). Secondly, I created the first mv and its log.
Lastly, I created the second mv from the first mv. This time I used the pivot function, but it cannot work now.
--1 create mv log
drop MATERIALIZED VIEW LOG ON target;
drop MATERIALIZED VIEW LOG ON targetextension;
drop MATERIALIZED VIEW LOG ON brand;
CREATE MATERIALIZED VIEW LOG ON target with rowid, sequence(id);
CREATE MATERIALIZED VIEW LOG ON targetextension with rowid, sequence(targetid,brandid,EmailPermission,NumberOfAllOrders);
CREATE MATERIALIZED VIEW LOG ON brand with rowid, sequence(brandid, brandname);
--2 create the first mv and it's log
drop MATERIALIZED VIEW mv_target1;
CREATE MATERIALIZED VIEW mv_target1
REFRESH FAST START WITH SYSDATE
NEXT SYSDATE + 1/1440
AS
select t1.rowid t1_rowid, t2.rowid t2_rowid, t3.rowid t3_rowid,
t1.id targetid,
t3.brandname,
[code].....
--3 create the second mv
drop MATERIALIZED VIEW mv_target2;
CREATE MATERIALIZED VIEW mv_target2
REFRESH FAST START WITH SYSDATE
NEXT SYSDATE + 1/1440
AS
select * from mv_target1
pivot(max(EmailPermission) EmailPermission, max(NumberOfAllOrders) NumberOfAllOrders for brandName in ('XXX' XXX,'YYY' YYY ,'ZZZ' ZZZ));
Now, Here is a problem, it throws "ORA-12015: cannot create a fast refresh materialized view from a complex query". Then I used dbms_mview.explain_mview to see the reason, and it tell me the following
REFRESH_FAST_AFTER_INSERT "inline view or subquery in FROM list not supported for this type MV"
declare
lv_sqltext varchar2(4000);
begin
execute immediate 'truncate table mv_capabilities_table';
lv_sqltext := 'select * from mv_target1
pivot(max(EmailPermission) EmailPermission, max(NumberOfAllOrders) NumberOfAllOrders for brandName in (''XXX'' XXX,''YYY'' YYY ,''ZZZ'' ZZZ))';
dbms_mview.explain_mview(lv_sqltext,'nested=>TRUE');

View 5 Replies View RelatedOracle 11G - Update Is Very Slow On View?
Dec 7, 2012I have big trouble with some Update query on Oracle 11G.I have a set of tables (5) of identical structures and a view that consists in an UNION ALL of the 5 tables.None of this table contains more than 20 000 rows.Let's call the view V_INTE_NE. Each of the basic table has a PRIMARY KEY defined on 3 NUMBERS(10,0) -> INTE_REF / NE_REF / INSTANCE.
Now, I get 6 rows in another table and I want to update my view from the data of this small table (let's call it SMALL). This table has the 3 columns INTE_REF / NE_REF / INSTANCE.
When I try to join the two tables :
SELECT * FROM T_INTE_NE T2
WHERE EXISTS ( SELECT 1 FROM SMALL T1 WHERE T2.INTE_REF = T1.INTEREF AND T2.NE_REF = T1.NEREF AND T2.INTE_INST = T1.INSTANCE )
I get the 6 lines in 0.037 seconds
When I try to update the view (I have an INSTEAD OF trigger that does nothing (just return for testing even without modifying anything), I execute the following query :
UPDATE T_INTE_NE T2
SET INTE_STATE = -11 WHERE
EXISTS ( SELECT 1 FROM SMALL T1 WHERE T2.INTE_REF = T1.INTEREF AND T2.NE_REF = T1.NEREF AND T2.INTE_INST = T1.INSTANCE )
The 6 rows are updated (at least TRIGGER is called) in 20 seconds.
However, in the execution plan, I can't see where Oracle takes time to achieve the query :
Plan hash value: 907176690
[code]....
Predicate Information (identified by operation id):
2 - access("T2"."INTE_REF"="T1"."INTEREF" AND "T2"."NE_REF"="T1"."NEREF" AND
"T2"."INTE_INST"="T1"."INSTANCE")
Note- dynamic sampling used for this statement (level=2)
Statistics
-----------------------------------------------------------
3 user calls
0 physical read total bytes
0 physical write total bytes
0 spare statistic 3
0 commit cleanout failures: cannot pin
[code]....
I get exactly the same execution plan (when autotrace is ON).Furthermore, if I try to do the same update on each of the basic tables, I get the rows updated instantaneously.

Replication :: Oracle 10g - Create Materialized View
Jun 16, 2008We are using Oracle 10g rel 2. The replication is setup on 1 server which is in City A, and the snapshot server is in City B.
City A .
Create materialized view log on table-a
with primary key
including new values.
City B database.
Create user test_rep identified by test
grant connect, resource, create any materialized view , table, view , procedure to test_rep.
Create materialized view city-A_db_MV
refresh fast
select * from cityA.Tablea@city-Adb
When i select from city-A_db_MV, it showed the complete table-A of city-A database.
Now if we make any changes to City-A table at the Master site, will it be propagated automatically to the MV site.
I guess we need to create jobs to push / or refresh fast .. isnt it. But exactly how to do it is a question.
Secondly if we make a replication group at Master site at city-A db, how do we refresh that Group and how to monitor whether it is refreshing on time or not? do we need to see the jobs every now and then.
but still a lot of questions unanswered, even though i had read the documents earlier.
1-The MView was created without identifying that after what interval it will be fast refreshed.
2- How to Manually refresh it. Does it support On Commit, I think it is not.
3- Where should be we make a group and then add the table to that group and refresh that group.
Should this group belongs to the Master Site or to MV site?

Refreshing Materialized View In Oracle SQL Developer?
Apr 6, 2010I have a database schema with a Materialized View (MV) that updates a products table shown on a website. This schema was recently imported to an 11g database from 8i, but since this import I have been unable to refresh my schema's Materialized View.
The MV_PRODUCT_MASTER Materialized View attaches price data to product data that is stored in a normal WEB_PRODUCT table, and create an MV table as a result. The output MV table is what the website pulls data from to display to the site users. Since it is an MV table, this table cannot be edited directly. In order to change, say, a product description, I need to alter the description field in WEB_PRODUCT and manually refresh the MV_PRODUCT_MASTER table. Only through the refresh will the upstream edits appear in the MV_PRODUCT_MASTER table and be visible on the website.
In my old 7.6.0.11 copy of TOAD, I could manually refresh these MVs easily, by opening the "Snapshots" tab, right clicking on the MV I wanted to refresh and selecting the "Refresh" option. Since the schema was imported to 11g, I have been using the Oracle SQLDeveloper tool to manage the schema. SQLDeveloper doesn't have a clear method for manually refreshing an MV, or else the method I am using isn't working.
If I right click on the MV_PRODUCT_MASTER Materialized View object, and choose "Other Actions", I see the following choices:
Shrink Materialized View
Compile Materialized View
Force Materialized View Refresh
Rebuild Materialized View
I assumed that -Force Materialized View Refresh- was the right choice, and chose that. This option displays the SQL:
alter materialized view "WEBADMIN"."MV_PRODUCT_MASTER" consider fresh
When I apply this, I get the message: Materialized view - MV_PRODUCT_MASTER - has been set torefreshed. However, no changes appear in the MV output table. i.e. if I make a specific change to a row in the WEB_PRODUCT table, the change is not being carried into the MV_PRODUCT_MASTER table, so that indicated that the refresh is not actually happening. The MV table appears to believe it is being refreshed:
REWRITE_CAPABILITY GENERAL
REFRESH_MODE DEMAND
REFRESH_METHOD COMPLETE
BUILD_MODE IMMEDIATE
FAST_REFRESHABLE NO
LAST_REFRESH_TYPE COMPLETE
LAST_REFRESH_DATE 06-APR-10
STALENESS UNKNOWN
But it isn't showing any changes.What am I doing wrong? Is there a plain SQL statement I can run in order to run these refreshes, instead of using the SQLDeveloper GUI?
