How to refresh materialized views
I'm following the steps to migrate a 12.0.6 financials database to OATM (model Tablespace Oracle Applications). One of the steps say to "perform a refresh all materialized views complete." This step is not part of the Oracle OATM utility. I wasn't able to find much on Metalink on this one. How to achieve this? Thank you... ColinColin,

The Materialized View - ORA-12052: is unable to fast refresh materialized view
Hello
I was hitting my head all day trying to create materialized views. I have made some progress, but have hit a brick wall, unfortunately!
Basically, I have been invited to take a view and see if I can get the benefits of performance by transforming all or part of it in materialized views. Because the underlying tables of the config is updated quite frequently, I want to fast refresh materialized views on commit. However, when I try to create a materialized view containing an outer join in an aggregated materialized view table, I get ORA-12052: is unable to fast refresh materialized view.
I went through the documentation and also Rob van Wijkvery useful series of blogs on the topic (especially http://rwijk.blogspot.co.uk/2009/09/fast-refreshable-materialized-view.html) but have not found anything that matches. Maybe I missed something somewhere along the line, or maybe I'm asking just something completely impossible?
My db is 11.2.0.2.
Here's the test scripts, I've worked with that:
drop materialized view test1_test2_mv;
Drop materialized view test2 journal;
drop table test2;

drop materialized view test1_mv;

Pivot can be used in fast refresh materialized view?

So, the answer is Yes, we can use Pivot with Materialized view but:
1 MV must be full refresh.
2 oracle version should be 11 g; of course the pivot is available in Oracle 11 g.If this answers your question, please close the message, otherwise continue.

Hi all
I created a procedure to refresh materialized views:
create or replace procedure refresh_MV1 is
Start
dbms_mview. Refresh('Materialized_view_1','C')
exception
while others then
INSERT into tablelog_mv (sysdate, 'Materialized_view_1', substr(sqlerrm,1,200));
end;
When I run run this procedurev (exec refresh_MV1), I am getting following error:
due to: ORA-12018: following error occurred during the generation of code for "ISGCOS". «Materialized_view_1 "ORA-00942: table or view is no ORA-00942: table or view does not exist»
But if I run anonymously without creating a procedure as below, it works very well and the matte view gets updated:
Start
dbms_mview. Refresh('Materialized_view_1','C')
exception
while others then
INSERT into tablelog_mv (sysdate, 'Materialized_view_1', substr(sqlerrm,1,200));
end;
I couldn't understand what could be the problem?
Thank you
ChrystellePrivileges on tables and views must be granted directly to the user when they are referenced in the procedures. Grants to the roles will not work.
Most likely your username has been granted privileges via a role
grant all on Materialized_view_1 to myRole; grant myRole to myUser; -- this won't give you the privileges in a procedure
You have the privileges directly
grant all on Materialized_view_1 to myUser

Fast refresh materialized view problems
I have two databases (A and B).
In A database, user NICK has a table called COLOUR_MASTER.
Also in this database, NICK issues creating materialized command newspaper view colour_master with the primary key, including the new values (and Yes, there is a primary key defined for this table)
In database B, there is a link of database called A_LINK, connect, Nick, identified by password using 'dbA ';
In database B, user IAN also creates a materialized view CM_MV cool off quickly in select * from colour_master@A_LINK
This statement is done correctly, and there are several million lines in CM_MV when it's done.
Immediately, IAN issued this command:
Start
dbms_mview. Refresh ('CM_MV');
end;
.. .and after a small pause, it gets the error
ORA-12008: error path refresh materialized view
ORA-02068: following sever error of A_LINK
ORA-03113: end of file on communication channel
One more + "select count (*) of colour_master@A_LINK" + subject immediately manages to return the correct number of records in the database so A 3113 is a bit misleading, I think that, in this case have crash, the database remains accessible at all times, there is no network problem (database A and B are both located in the same server so it of not like I'm trying of) connect to halfway around the globe).
The only thing I can think is that there is a permissions issue causes this error. The creation of MV because is made via a link, it is not a problem of IAN see all appropriate, but once the updates come into play, it is perhaps.
Any who can shed light on why I can't do the fast refresh from the view, I can create joyfully, please?I'm surprised no one asked you to do what is obvious: try to do a select * from colour_master@A_LINK, without that being wrapped in a create materialized MATERIALIZED view. Just do a simple select * from...
My bet is that you will get an error ORA_22992 can not use selected from the remote tables LOB Locators . And if you can't do a simple select * in a remote table, I suspect that you can reasonably expect Fireworks when you try to create or refresh a view materialized on such a thing!
Here's a quick test:
In the 1 database:
=========SQL> create table A (col1 varchar2(2), col2 clob); Table created. SQL> alter table A add constraint A1 primary key (col1); Table altered. SQL> insert into A values ('AA','This is an entry into a clob column'); 1 row created. SQL> commit; Commit complete. SQL> create materialized view log on A with primary key including new values; Materialized view log created.
In the database 2
=========SQL> connect ims_global/v0yager1@ussd Connected. SQL> create materialized view B refresh fast as 2 select * from A@remotedb_link; Materialized view created. SQL> exec dbms_mview.refresh('B'); BEGIN dbms_mview.refresh('B'); END; * ERROR at line 1: ORA-12008: error in materialized view refresh path ORA-02068: following severe error from REMOTEDB_LINK ORA-03113: end-of-file on communication channel ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2251 ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2457 ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2426 ORA-06512: at line 1 SQL> drop materialized view B; Materialized view dropped. SQL> create materialized view B refresh fast as 2 select col1 from A@ims_link; Materialized view created. SQL> exec dbms_mview.refresh('B'); PL/SQL procedure successfully completed.
Which seems to reproduce your problem rather well, I think.
I don't know if there is no work around for this. I mean, obviously you can't miss the CLOB column in your statement of 'create a MV' as I just did, but I don't know if you're still allowed or expected to be able to create a MV on lob columns and that such and such correction will allow you to do. Maybe someone else can provide this information.
But at least you won't have to play Russian roulette with your init.ora parameters!

1. How about helping to keep the forum clean by examining your 85 not resolved previous issues and give credit relatively USEFUL or RESPONDED to those who helped you in the past.2. read the FAQ at the top right of the page and view information about your system and your software so that we know what you're working with.
3 ask your question in the body of the thread. Don't tell "of ideas.
What is your question? Is this an academic question or you have a real problem that needs to be addressed?
If you have a problem producing the DDL for the materialized view, and information about the type of discount that has been set up for this. Is there a newspaper view materialized on the underlying tables?
The simple answer to your quest is to use UPDATE them on REQUEST and check the base tables before making a manual

How to fast refresh materialized view parallel
We have Oracle 11.2.0.1 on Redhat 5.2. We use a dozen views fast refresh materialized in our application.
Occasionally refresh MV takes longer than the refresh interval.
One of the ways to improve the performance of refresh MV is to update at the same time, for examplehttp://www.dba-oracle.com/t_materialized_views_refreshing_performance.htm - Use parallel DML - Oracle author Michael Armstrong Smith notes "I've done parallel materialized view refreshing on tables recently and improved the load times considerably. Rather than having one load which took 2 hours, I run 4 parallel loads, one for each partition. The length of time for the whole process is now determined by how long the biggest partition takes to load. In my case, this is 40 minutes, with two 30 minute loads and one 20 minute load. Overall I am saving 1 hour 20 minutes. I can now add further partitions and do the same thing. My only limitation is the parallel loads because I don't have unlimited processing power. {code} My master tables are not partitioned, but think parallel will still better than non-parallel. Now the question, how to make refresh parallel. According to the paragraph cited above, Use parallel DML appears doing the job. Can someone confirm that. We use {code} alter materialied view MV_OFFENSE parallel REFRESH FAST start with sysdate next sysdate+ 1/24; {code}to schedule refresh. Does the parallel clause here parallels query the MV or refresh the MV? Any other way to make MV refresh parallel? Thanks

Problem with a complete refresh materialized view when using rownum
Hi all
I had a problem with rownum when complete using Refresh
I use rownum when you create the materialized view, and this is the generation properly. But the question was when I even refreshing, rownum was not get sorted in ascending order.
anyone encountered this scenario
rownum is determined as the line came out, also "order by rownum" does absolutely nothing.

And later, when I run utlu112i_8.sql again, he said: materialized views are being updated
What's not here?
In addition the report itself does not much tip how to solve the problem, how to fix the problem? Is the report correct?

Hello
Version: Oracle 10g
I'm not having any expertise on materialized views (now start reading about M views). A friend of mine asked this question. If we need updating the display of materialzied on ad hoc basis is all avialable API.
For example materialized view the code (I changed the names of the objects)

Taking some time to refresh materialized view
I'd like to understand why refresh of the materialized view takes more time than to run the sql code of the materialized view.
For example, I have a test_mv of materialized view that is created as below; When I simply run the select statement I get the result in 34 seconds, while if I try to update help
It takes about 74 dryBEGIN DBMS_MVIEW.refresh ('wi_mv7_monthly','C',ATOMIC_REFRESH=>false); end; /

SQL select statement some readings and refresh the views but mview reads and writes, so it consumes more time.
If you want to speed up the cooling you can use the Refresh method fast mview
