Am trying to create a materialized view as below
SQL> CREATE MATERIALIZED VIEW emp_view_73 BUILD IMMEDIATE REFRESH COMPLETE ON COMMIT

5 ||' '
6 ||em.employee_lname employee_name,
[code]....
ERROR at line 12: ORA-12054: cannot set the ON COMMIT refresh attribute for the materialized view
we 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?
we 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:
Oracle 11.2.0.3
I'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?
There 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?

View 28 Replies View RelatedI 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:

I have a list of materialized views in schema A. I want to create a refresh group and then refresh it from Schema B (Dynamically-run time based on some criteria). What Grants are necessary on schema B in order for it to be able to create and refresh the groups on Materialized views in Schema A.
I know that one of the Options is to, GRANT ALTER ANY MATERIALIZED VIEW as a SYS user. But I do not have any SYS privileges.
Am getting an error while trying to refresh a Writeable Materialized view using the following statement -
exec dbms_mview.refresh('schema_name.MV_name','C')
Error:-

The Primary Key Constraint on the base table/MV is deferrable, the base table and the MV are in different schemas and the user trying to refresh the MV has an explicit grant on "ALTER ANY MATERILIZED VIEW" and "SELECT ANY TABLE" through a role.
Its refreshing successfully when I make the PK constraint (Base Table, MV) NOT DEFERRABLE (or) when I explicitly grant "SELECT ANY TABLE" to the user trying to refresh the MV.
I have created a Table with one column in user 'Test' Database 'Test'. Then i have created a Materialized view based on the Table in 'TestMV' in same database 'Test'.working fine. But after adding one column in the table, if i go to refresh the Materialized view the following Error has occured.

We are facing serious problem while refreshing materialized views using fast refresh option in ORACLE..For the very first time we are performing Complete refresh of data from DB1 to DB2 for few tables.Ongoing we are performing Fast Refresh.Sometimes the fast refresh works fine without any error and sometimes it fails with the below error.
ERROR at line 1:
ORA-32320: REFRESH FAST of "CIR"."C_BO_COMM" unsupported after

I have two database with the same procedure and the same objects. They run at the same time, however, there are times when i get the error on the other database while the other database runs the procedure without any error.
When i checked the net, they say that this error is caused by data that is old, so the solution is to make the source a predecessor of my procedure/job. But what i am thinking is that how was it possible for the other database to run it completely even if it is not yet linked as the successor of the source?
can we change the existing materialized view to normal view? if yes how?

View 7 Replies View RelatedI 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.
i have created FAST refresh materialized view.it is eligible for FAST refresh because when i executed SELECT * FROM USER_MVIEWS i could see FAST_REFRESHABLE=DIRLOAD_DML and STALENESS=STALE and it is not getting refreshed(through DBA_JOBS). Why it is in STALE status and how to resolve it. and one of my materialized views is in NEEDS_COMPILE status
View 3 Replies View RelatedA scheduler job is there to refresh some materialized views. All the views are run under single job name. Some mviews are not refreshing and those are not refreshing in the next run too.if we run those mviews manually then they are working fine from then . after some days those views which i told before are not refreshing and this happens frequently and i check the job_run_details views also and i am not seeing any errors in that.
