View 3 Replies View RelatedReplication :: Oracle 10g - Create Materialized View
Jun 16, 2008We are using Oracle 10g rel 2. The replication is setup on 1 server which is in City A, and the snapshot server is in City B.
City A .
Create materialized view log on table-a
with primary key
including new values.
City B database.
Create user test_rep identified by test
grant connect, resource, create any materialized view , table, view , procedure to test_rep.
Create materialized view city-A_db_MV
refresh fast
select * from cityA.Tablea@city-Adb
When i select from city-A_db_MV, it showed the complete table-A of city-A database.
Now if we make any changes to City-A table at the Master site, will it be propagated automatically to the MV site.
I guess we need to create jobs to push / or refresh fast .. isnt it. But exactly how to do it is a question.
Secondly if we make a replication group at Master site at city-A db, how do we refresh that Group and how to monitor whether it is refreshing on time or not? do we need to see the jobs every now and then.
but still a lot of questions unanswered, even though i had read the documents earlier.
1-The MView was created without identifying that after what interval it will be fast refreshed.
2- How to Manually refresh it. Does it support On Commit, I think it is not.
3- Where should be we make a group and then add the table to that group and refresh that group.
Should this group belongs to the Master Site or to MV site?

Mar 13, 2008I have to create a materialized view for a table which does not have index on any field.
While creating a Mview i am getting an error "TABLE DOES NOT HAVE THE PRIMARY KEY CONSTRAINT".
application developers do not want to create an index on the base table onto which MView is to be created.
is there any way to create a materialised view for the table without index, or is it necessary to have the index on the base table before creating MView on it.
Replication :: Create Materialized View Without Having Any Data In It
Nov 5, 2008How I can create a Materialized View without having any data in it.
For e.g.
I create a Materialialized View based on a View.
CREATE MATERIALIZED VIEW test_mv
REFRESH FORCE ON DEMAND
AS
SELECT * FROM test_view
In the above case the data fetched by the view test_view gets stored in the Materialized View test_mv. Suppose I want materialized view test_mv to get created with all the columns of test_view but not the data. I will refresh the materialized view test_mv later for data as and when required.
What shall I do for immidiate formation of materialized view test_mv without data.

View 1 Replies View RelatedSQL & PL/SQL :: Regular Table Or Materialized View - Clone Table Data In Another Database
Jul 19, 2010 There is a requirement to make a table data in a database (eg: HR database) available in another database (eg: EMP database), instead of accessing it using database link. In EMP database(where data needs to be cloned), data will only be queried and no write operation will be done. Data in remote database (eg: HR DATABASE) will be occassionally fully truncated and reinserted. The plan is to do a similar truncate and reinsert of data (from HR database) into EMP database monthly once using dbms scheduler job. So basically data in just one table needs to be cloned in another database.
Question: For this situation, is a regular table or Materialized view the right choice to clone the table in EMP database and why? The table in HR database (remote database) is not very big.

Materialized View Cannot Use Prebuilt Table
Aug 18, 2010We are in the process of migrating our databases to a hosting provider (10g Sun -> 11g LINUX.) A (former) data architect at our business had this (nightmare) situation implemented:
- have materialized views created
- after creation of mat views(and associated tables), add additional audit columns to the table that are populated by triggers, not by the MV. All data is important.
In order to get all of the data to the hosting provider, we data pump export the full schemas (which include the associated MV tables), have the provider DBA's import (all the materialized views failed on import, but the associated MV tables were created/populated), and I'm now attempting to fix the MV code to get them recreated. Over 100 MV's, most of which have these extra audit columns, and a number of the remote master/source tables do not have primary keys so using the by rowid option. An edited example (object names changed to protect the innocent) - using CAST to include the audit columns:
CREATE MATERIALIZED VIEW SCHEMA1.ACCOUNT
ON PREBUILT TABLE
USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE(INITIAL 512K NEXT 512K PCTINCREASE 0 BUFFER_POOL DEFAULT) TABLESPACE S_TS_01_INDX
REFRESH FAST
ON DEMAND
WITH ROWID USING DEFAULT LOCAL ROLLBACK SEGMENT DISABLE QUERY REWRITE
AS SELECT
ACCOUNT.GROUP_ID GROUP_ID
...
...
cast(null as date) CREATE_PROCESS_DATE,
cast(null as varchar2(20 CHAR)) CREATE_PROCESS_ID
FROM SCHEMA2.ACCOUNT@REMINSTANCE.WORLD ACCOUNT
/
ORA-12058: materialized view cannot use prebuilt table
IF remove "with rowid", get error that cannot create because no primary key on source table.
Online options seem to be (1) do not use prebuilt table (in which case we'd lose the additional audit data) or (2) add a primary key on the master table (we're not in a timeline to make & test changes to various production source tables.)
Other thoughts on how to get this data migrated/populated? This needs to be a lift and drop as much as possible - any type of rewrite/restructuring is out of the question.
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:

Feb 1, 2012I plan to create a copy of original partition table as below in source database DB1.
create table tblname as select * from sourcetab;
The purpose i am creating copy of original tables is i want to have same partition tables with data in target database DB2 (where the partition feature is diabled).
So i am creating copy of original partition tables ,will then create dump of duplicate tables using export method and then load the dump into target database using import.
Both source and target database are in different servers. Partition is disabled in target database. Partition table size is 2GB and it has 5 partitions P1,P2,P3,P4,P5 .Each partition is of size 100 MB. Count of partition table is 15805412
1.My question is would there be any problem while loading dump into target database (where the partition feature is not enabled)?
2.Is it feasible to create a copy of partition tables using below statements in same database ?
create table tblname as select * from sourcetab;

Convert Some Existing Materialized Views (fast Refresh) To Partition Materialized Views
Jul 7, 2010I have to convert some existing materialized views (fast refresh) to partition materialized views.
Database version is oracle 10.1.0.4. I have decided to use on prebuilt table option to do the partitioning as it minimizes the time to transfer from the master site.
1) stop replication
1) create interim tables with similar structure as the materialized views
2) transfer all data from the materialized views to the interim tables
4) script out the materialized views structure and add in on prebuilt table option in the scripts
5) drop the materialized views
6) rename the interim tables with the same name as the materialized views
7) run the scripts to create the materialized views with on prebuilt table option
8) refresh the newly created materialized views -> it should take a short time since I am using on prebuilt table option
But I am facing one major issue. That is if I drop the materialized views, the materialized view logs of the master tables are purged. When the materialized views are refreshed fast, there are some data missing. the data that are purged out when the materialized view are dropped.
Do you happen to know other ways that existing materialized views can be converted to partitioned materialized views? Do you have any workaround to prevent the materialized view logs from being purged?

View 3 Replies View RelatedCreating 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?
