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?
Creating Materialized View Log
Feb 7, 2013There are 2 databases, database A and database B. Database A is Oracle 11.2.0.2 which runs on linux and Database B is Oracle 11.2.0.2 which runs on windows xp machine. In database A, there are 100's of tables which are being updated every 10 minutes or 15 minutes. For reporting purpose, the developer wants to run report for the tables. But since database A is being updated every now and then, generating reports takes almost 15 to 20 minutes. So the reports can be generated in Database B. Once in a day the database B should have the updated data from database A so that the reports can be generated in database B with less time. What could be the best solution for the database B to have the updated data on daily basis from database A in oracle?

Error In Creating Materialized View With DB Link?
Aug 7, 2013we have the following requirement for creating materialized view.
In database "DB1", a table "abc" is there in "user1" schema.
In database "DB2", in "user2", we are accessing the "abc" through DB link "DBL1" to DB1:
select * from user1.abc@DBL1;
we have created a public synonym for "user1.abc@DBL1" as "sabc".
In database "DB3", we need to create the materialized view to access "abc" in DB1 through DB2. we are not allowed to access "DB1" directly from "DB3". so we create a db link as "DBL2" in "DB3" to "DB2".
when i try to create a materialized view as below:
create materialized view abc_mv
as
select * from sabc@DBL2;
But got the error as "synonym translation invalid". When i access the SQL statement separately as below
select * from sabc@DBL2, its working but in Materialized view, it shown that error. Even i tried with schema name as well like "user2.sabc@DBL2" , but that also thrown same error.
Is there any option available for this type of creating materialized view?
PL/SQL :: Creating A Refresh On Commit Materialized View?
Jul 18, 2013I am trying to create a commit on refresh materialized view so that whenever I perform DML followed by commit on Master table it should get quickly reflect on my Materialized view. I have given SELECT on table privilege to user where this view will be created On Master:

From Scott:CREATE MATERIALIZED VIEW scott.hremp REFRESH FAST ON COMMITAS SELECT * FROM HR.EMPLOYEES; ERROR at line 4:ORA-01031: insufficient privileges Then I Grant all on EMPLOYEES table to SCOTT.

Even after this I am not able to create materialized view and now getting Table not Exist error:

Also I want to know why I needed to GRANT ALL to HR for creating this materialized View.
Error In Creating Update Table Materialized View
Aug 28, 2013we are trying to create a materialized view (MV) which would access the remote database through db link. Now we need to do update on the local MV so that it should be reflected on the master table.
There is no primary key on this table and we are using "complete refresh" option. since we dont have control over remote database, we are not allowed to create MV log over there.
in this scenario, if i try to create updatetable MV with complete refresh, we are getting below error:
SQL Error: ORA-12013: updatable materialized views must be simple enough to do fast refresh
how to create such MV on this scenario?
our environment is:

View 7 Replies View RelatedSQL & PL/SQL :: Materialized View
Jul 7, 2010I have requirement to create materialized views. The design states to use Complete refresh. Now I am using WITH ROW_ID clause.
1. Question - what are the criteria to decide between WITH PRIMARY KEY & WITH ROW_ID clauses? I referred oracle doc, but couldn't exactly get this.
2. Background - The oracle doc mentions that - Primary key materialized views are the default type of materialized view. The master table must contain an enabled primary key constraint, and the defining query of the materialized view must specify all of the primary key columns directly.
Question - I saw some existing materialized views in my project using WITH PRIMARY KEY clause, but all of the primary key columns are not part of the Select query, but still these views are working fine, how is this possible?
3. Background - The oracle doc mentions that - Rowid materialized views must be based on a single table and cannot contain any of the following:
■Distinct or aggregate functions
■GROUP BY or CONNECT BY clauses
■Subqueries
■Joins
■Set operations
Question - But I have created a Rowid materialized view selecting data from more than one table & defining query involving outer joins. This materialized view got created & getting refreshed (complete refresh). But again this is contradicting with Oracle' statement.

SQL & PL/SQL :: Materialized View Recreate
Oct 2, 2012we have a materialized view (in Oracle 11g), usually this MV we easily drop and recreate it.
But last few days, i am trying to drop a MV, but running a long time but no result and it keeps running. not dropped also.
Bcos, db performance is good since we tried to a view using script, it is fine. Problem seems only with Materialized view.
where and how to check what is the issue?
Invalid Materialized View?

I looked on every object reference in the MV, all permissions - can't find anything.I dropped MVs and created them no errors. Status changed to VALID. I decided to re-COMPILE them (because I saw public synonyms for MVs as INVALID). After compilation status changed back to INVALID.Oracle 11.2, Solaris 10.
