Problems in creating Materialized View from 10g R2 to 11g

Hi,
We have two databases in 10g Release 2. These databases are on two different servers and we use
Materialized views to replicate data between these servers. We are currently using 64 bit version of
oracle 10g release 2 for LINUX.
Oracle Database 10g Release 10.2.0.1.0 - 64 bit Production
PL/SQL Release 10.2.0.1.0 - Production
CORE 10.2.0.1.0 Production
TNS for Linux: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production
We use CENTOS 5 - 64 bit edition
We upgraded one of the databases to 11g (We exported the data from old database and
imported it in new database) . Then we tried to create a Materialized view with incremental refresh
on it where the base table is in the second Oracle 10g database.
The problem is that it is not letting us create the view with FAST Refresh. It kept on giving ORA-12028
error. We tried different remedies suggested on forums like creating a view with ROWID, but still it
continued giving us the same error. We also synchronized the characterset of Oracle 10g and Oracle 11g
installations but still it did not work.
Our base table size is pretty large (over 10 Million records) and if we do a full refresh, it takes hours to
refresh it.
Without incremental refresh, we will not be able to fucntion, and to upgrade both database simultaneously
we will need a large down-time which also we can not afford.
Please advise what should we do.
Best Regards

Hello,
Yesterday I met the same problem and very sad about this, however, my story is much more complicated (I think so).
I have 6 databases:
2 - 11g
2 - 10g
2 - 9i
Every database of each release has different characterset(UTF8 and AL16UTF16).
I am trying to create Materialized view with FAST REFRESH on Oracle 11g, when master tables are located on 10g database and 9i database.
Materialized view, which points to 9i database, was successfully created.
Materialized view, which points to 10g database, gets ORA-12028
Like you, I tried many notes from METALINK and thought at the begining that the problem is my characterset. But, when the materialized views were successfully built on Oracle 9i database, I understood that the problem is something else.
Did you find the actual reason why this issue does not work??
Thanks,
Alex

Create materialized view from Designer9i

Is there a way to create a materialized view from Oracle Designer 9i that will that have a header that look like this :
CREATE MATERIALIZED VIEW XXXXXXXXX
REFRESH COMPLETE ON DEMAND WITH PRIMARY KEY
Instead of this :
CREATE MATERIALIZED VIEW XXXXXXXXX
REFRESHWITH ROWID
Thanks
Jérôme

yes.
as long as you have the privilege.
but be careful, it may causing locking issue in the SQL Server side.

Problems while facing Materialized Views

Hello All,
I am facing some problems while creating Materialized Views.
Senario.
SCOTT USER:
sql> Grant select on emp to Public;
sql> Create materialized view log on emp;
Connected to LDB User
sql> CREATE MATERIALIZED VIEW mt_emp
Refresh fast
as select * FROM scott.emp;
I am getting error.. Stating that Table doesnt Exist.
Please tell me the Reason..
Note:
If there is No Log on table Emp then it is throwing the error that there in no LOG on the EMP Table.
Now when I create a Log on EMP table --> Then it is giving the Problem that Table doesn't Exist.

Hello paragjp
The Below are the Steps I am Implementing..
Connect as Scott User.
SQL> Grant select on Emp to Public;
SQL> Create materialized view log on emp with primar key;
Now I will be Connecting to Other User Say LDB
Connect as LDB User
SQL> CREATE MATERIALIZED VIEW mt_emp
Refresh fast
as select * FROM scott.emp;
-- The Below Errors are comming
ERROR at line 3:

Problem with Materialized Views in 10g

Hi All,
I am creating a Materialized View like
CREATE MATERIALIZED VIEW mvname TABLESPACE SYSTEM BUILD IMMEDIATE REFRESH WITH ROWID FOR UPDATE AS ( SELECT a,b,c FROM table_a,table_b,table_c WHERE cond );
I am getting an error
SQL Error: ORA-12013: updatable materialized views must be simple enough to do fast refresh.
Can anyone tell what is the problem?
I have included rowid of all three tables in select clause.

Hi,
From Oracle Docs:
ORA-12013: updatable materialized views must be simple enough to do fast refresh
Cause: The updatable materialized view query contained a join, subquery, union, connect by, order by, or group by caluse.
Action: Make the materialized view simpler. If a join is really needed, make multiple simple materialized views then put a view on top of them.

      ) AS XML_DATA
FROM authority p -- Parent table
WHERE p.auth_type = 'Person';The views are created fine and they work perfectly for what we need. The problem is the refresh when we edit the base tables. Ideally, it should take a couple seconds. Right now, it takes a couple minutes. XMLTYPE is one problem and the Complex Query exception is the other. If there is a work-around for fast refresh, please let me know. Greatly appreciated.

Besides XMLTYPE column, your MV definition has a subquery which prevents it from being fast refreshable.
I could not find any specific reference in documentation about restriction on XMLTYPE (or CLOB) columns but it seems logical that oracle will not be able to keep track of changes to binary data. What does DBMS_MVIEW.EXPLAIN_MVIEW generate for your MV definition? That should tell you which all conditions (for FAST REFRESH) your MV violates. Since you can not create a MV LOG to include XMLTYPE column, it will not be possible to create a FAST REFRESHABLE MV that includes the XMLTYPE column.
I am afraid there is not much you can do here unless you are prepared to change the way data is stored in your base tables. If you can store data in base tables using standard data types instead of binary/XML storage, you might be able to create a FAST REFRESHABLE MV.

You could try the DBMS_MVIEW.TUNE_MVIEW and check if you can modify you materialized view or "refactor" it in a smaller, fast refreshable part that you could combine later to the sysdate/rownum part of it.

ORA-04052 creating Materialized View

ORA-04052 creating Materialized View
Hi All !!
I'm trying to create a Materialized view and his query definition uses an active public database link. When I ran the script for creating the view I get the following message:
ERROR in line 1:
ORA-04052: error occurred when looking up remote object
USER.TABLE@ORCL2
ORA-00604: error occurred at recursive SQL level 1
ORA-03106: fatal two-task communication protocol error
ORA-02063: preceding line from ORCL2
But when I execute his definition query all is ok, the query works fine.
I mean, I'm using the following sentence to create the view:
CREATE MATERIALIZED VIEW my_view TABLESPACE tbsname BUILD IMMEDIATE
REFRESH FORCE
WITH ROWID
ENABLE QUERY REWRITE
AS
SELECT ...
FROM SCHEMA_NAME.TABLE_NAME@ORCL2;
The above sentence give me ORA-04052. Nevertheless the SELECT... FROM SCHEMA_NAME.TABLE_NAME@ORCL2; works fine...
I checked for the GLOBAL_NAMES parameter and it is set to FALSE. Please help me, How can I fix this problem ?
I'm using Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Production running over Win XP for create the view.
The Database Link points to Oracle Database 10g Release 10.1.0.4.0 - 64bit Production running over Solaris
Thanks in advance !!

I've checked the NLS_LANG settings in both servers, and are set to AMERICAN. NLS TERRITORY are set to America also.

Replication of database views/materialized views from big oracle to mobile client

Hi all,
Has anyone done a replication of a view or a materialized view
from big oracle to oracle lite? I can get replication of a
database table happening(although I cant seem to find the table
when I log into the odb using msql) but it just doesn't seem to
work with views(hence the path I have taken which is to use
materialized views). Anyone? Cheers

Hello,
Yesterday I met the same problem and very sad about this, however, my story is much more complicated (I think so).
I have 6 databases:
2 - 11g
2 - 10g
2 - 9i
Every database of each release has different characterset(UTF8 and AL16UTF16).
I am trying to create Materialized view with FAST REFRESH on Oracle 11g, when master tables are located on 10g database and 9i database.
Materialized view, which points to 9i database, was successfully created.
Materialized view, which points to 10g database, gets ORA-12028
Like you, I tried many notes from METALINK and thought at the begining that the problem is my characterset. But, when the materialized views were successfully built on Oracle 9i database, I understood that the problem is something else.
Did you find the actual reason why this issue does not work??
Thanks,
Alex

Thanks William,
I tried with ON PREBUILT TABLE, just to see what happens.
Building on my OP:
SQL> create table iot(agency varchar2(8) not null, company varchar2(8) not null
2                  ,constraint iot_pk primary key (agency,company))
3 organization index;
Table created.
SQL> insert into iot select distinct agency, company from anormal;
4 rows created.
SQL> commit;
Commit complete.

Looks like that IOT select'ed from is indeed the MV:

Create HEAP organized MV or
Create and maintain IOT

Creating Materialized View in Toad

As with every new endeavor - come new questions.
I am trying to create a materialized view via toad (first time doing this). Now - toad is great, since it provides a kind-of wizard interface. Hence, one doesn't have to completely code in the create statement, with all of the options, etc.
Instead, in toad, one can (via the schema browser), go into the Materialized Views tab and click on create new. This opens a window with 6 tabs: Basic Info, Refresh Info, Physical Attributes, Query, Partitions & Subpartition Template.
In the Basic Info, one can put a check mark next to some of the following options:
-Build Deffered
-Parallel
-Cache
-Logging
-Using index
-Allow updates
etc.
I have read that build deferred refers to whether or not you would like the view to be created automatically or to be deferred.
Anyways, I tried to find Toad documentation to explain each of the options in-detail. No success. Hence, am researching each part piece by piece.
But - here is my question:
In the Query tab, we are asked to specify a query. I am assuming that the query does not have to be a full query, beginning with CREATE MATERIALIZED VIEW mv_table1 REFRESH FAST etc...
Since in this 'wizard', we are providing the MV name at the top of the dialog box, we are checking the 'options' in the other tabs, etc.
And so, I assumed that the query should merely be a select query in the window mentioned above.
So I entered the following:
select * from table1@remote_db;
When I go to verify the syntax, I get the error message: ORA_00911: invalid character. It seems to be pointing to my db_link (remote_db). I have been using this link throughout many places, w/o any problems.
Has anyone created a MV in toad before? Any links to good toad documentation would be helpful as well.
Thanks.

(This is fun... ;))
For anyone endeavoring this in the future, below I have attached the prerequisites required in order to create a materialized view (can also be found @ http://download-uk.oracle.com/docs/cd/B14117_01/server.101/b10759/statements_6002.htm):
Prerequisites
The privileges required to create a materialized view should be granted directly rather than through a role.
To create a materialized view in your own schema:
You must have been granted the CREATE MATERIALIZED VIEW system privilege and either the CREATE TABLE or CREATE ANY TABLE system privilege.
You must also have access to any master tables of the materialized view that you do not own, either through a SELECT object privilege on each of the tables or through the SELECT ANY TABLE system privilege.
To create a materialized view in another user's schema:
You must have the CREATE ANY MATERIALIZED VIEW system privilege.
The owner of the materialized view must have the CREATE TABLE system privilege. The owner must also have access to any master tables of the materialized view that the schema owner does not own (for example, if the master tables are on a remote database) and to any materialized view logs defined on those master tables, either through a SELECT object privilege on each of the tables or through the SELECT ANY TABLE system privilege.
To create a refresh-on-commit materialized view (ON COMMIT REFRESH clause), in addition to the preceding privileges, you must have the ON COMMIT REFRESH object privilege on any master tables that you do not own or you must have the ON COMMIT REFRESH system privilege.
To create the materialized view with query rewrite enabled, in addition to the preceding privileges:
If the schema owner does not own the master tables, then the schema owner must have the GLOBAL QUERY REWRITE privilege or the QUERY REWRITE object privilege on each table outside the schema.
If you are defining the materialized view on a prebuilt container (ON PREBUILT TABLE clause), then you must have the SELECT privilege WITH GRANT OPTION on the container table.
The user whose schema contains the materialized view must have sufficient quota in the target tablespace to store the master table and index of the materialized view or must have the UNLIMITED TABLESPACE system privilege.
When you create a materialized view, Oracle Database creates one internal table and at least one index, and may create one view, all in the schema of the materialized view. Oracle Database uses these objects to maintain the materialized view data. You must have the privileges necessary to create these objects.

Error while creating materialized view which using database link

Helo!
I'm getting error "ORA-00942: table or view does not exist" when I want to create materialized view.
Details:
1. On destination database I create a database link:
CREATE DATABASE LINK SDATABASE
CONNECT TO MYUSER
IDENTIFIED BY MYUSERPASS
USING 'ORCL';
=> Command "SELECT * FROM TABLE1@SDATABASE" returns data normally!
2. On source database I create MATERIALIZED VIEW LOG:
CREATE MATERIALIZED VIEW LOG
ON TABLE1
WITH PRIMARY KEY
INCLUDING NEW VALUES;
3. Now, when I want to create MATERIALIZED VIEW on destination database:
CREATE MATERIALIZED VIEW TABLE1
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE + 1/1440
WITH PRIMARY KEY
AS SELECT * FROM TABLE1@SDATABASE;
...I get error "ORA-00942: table or view does not exist"!
How is that possible if command "SELECT * FROM TABLE1@SDATABASE" returns data normally?
Thanks,
Voranc

And, I'm using Oracle 10g.

Error on creating Materialized view.

Hi,
I don't understand why it happens...
When I tried to creating materialized view, it shows a error "ORA-01013: User requested cancel of current operation".
I don't understand why it happens. I just waited it successfully created. But I didn't press any button.
Does it matter of size of joining table? I had same issue before. At that time I just removed some tables from the joining condition, this error was gone.
But at this time, I cannot exclude any other tables the select statement
Can anyone help me this issue, please?

Hi,
11g ( 11.2.0.3 ) has a problem with materialized views based on ROWID, resulting in the problem you mentioned.
A workaround is creating the MV's based on primary keyl.
There is also a patch available on MOS, to solve the problem ( thanks to a very long SR from me :-) )
It is known as bug 13657605 and the patch for it has the same number.
Remember to read the README, as this patch is only for 11.2.0.3 !!
Cheers
