Refresh Materialized view on request using db link

Hello

someone at - it how to refresh a materialized using db link view.

My scenario is I have MV in a scheme and I need to update it in Figure B. Is it still possible.

I tried updating using db link and wasn't able to do the same.

All entries on this?

Wow. It's a strange way to security.

Pivot can be used in fast refresh materialized view?

Hi, I have a question about materialized view nested mode fast refresh on Oracle 11 g (It support function of pivot, but oracle 10 g doesn't support).

When I created, he throws "ORA-12015: cannot create a view fast refresh materialized by a complex query.
Then I used dbms_mview.explain_mview to see reason, and it tell me the following
REFRESH_FAST_AFTER_INSERT ' view inline or subquery in LIST not supported for this type of MV.

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.

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

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!

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?

Refresh materialized views
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
Chrystelle
Privileges 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
```

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... Colin

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.

Materialized view: when to use a full refresh

Thank you in advance, I read in the book of the Oracle University - "a complete refresh of a materialized view is to truncate the existing data and reinsert all data based on detail tables, re-running the query definition to CREATE order. Quick updates apply only changes since the last update. My question is what we need to complete refresh because the data in the table created for the two methods are ultimately the same and fast refresh is more "quickly"?

Well, I don't know about the Oracle University book, but Oracle manual list a long list of restrictions when fast updating is not possible. I hope that answers your question.

How to stop refreshing materialized views if the source table is null
any ideas?
Probably not what you were hoping for, but here's a few ideas.

Your account shows - 113 (85 pending)
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
a: the best answer depends on what version of Oracle you are using and what is your actual configuration. Are your
MVs in REFRESH GROUPS? Who can make a difference in the response.

How can anyone help with this issue if you do not provide the information needed (FAQ)? Why is - someone MUST help if you show you don't appreciate help in marking questions to which answered once you have helped.

Fast refresh materialized views
Hi all

We have tables in the remote database and we created materialized views in our local database using the database but link to refresh these take a long time, so we can use fast refresh on these materialized views?

Kind regards
RAM
Look at ATOMIC_REFRESH option, if you set this to FALSE, you can see the performance because it will use the path of DIRECT ACCESS and TRUNCATE. Data will be unavailable while being refreshed well.

See you soon

I would first check "request" from the view of the DBA_SNAPSHOTS/DBA_MVIEWS dictionary information, if it reveals something obvious.

But it looks more like an internal error when processing the update. You can get more information on the follow-up to the session error. "Alter session set sql_trace = true;" before running the update should be sufficient. Then unplug and check the trace file generated error using "tkprof" and check the output or by searching manually "err =" in the trace file.

What 4 numbers of Oracle version do you use?

Kind regards

Refresh materialized view
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)
```
CREATE MATERIALIZED VIEW emp TABLESPACE sample NOCACHE LOGGING NOCOMPRESS NOPARALLEL BUILD IMMEDIATE USING INDEX
            TABLESPACE TS_SAMPLE_IX
REFRESH FORCE ON DEMAND
WITH PRIMARY KEY
AS
SELECT  empno
             ,ename
          ,deptno
FROM   [email protected];
```
Thank you

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

BEGIN
DBMS_MVIEW.refresh ('wi_mv7_monthly','C',ATOMIC_REFRESH=>false);
end;
/

It takes about 74 dry

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

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 example

http://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
