Dec 24, 2007
m trying to create replications of data from the M.V. site. to master site
/* AT MASTER SITE */
1. MASTER REPLICATE GROUP
2. MASTER REPLICATE OBJECT
3. REPLICATION SUPPORT
4. REPLICATION ACTIVITY
5. M.V. LOG
/* AT M.V. SITE */
1. MATERIALIZED VIEW (M.V)
2. DBMS_REFRESH.MAKE (REFRESH GROUP)
AND I AM NOT ABLE TO CREATE
1. CREATE_MVIEW_REPGROUP
2. CREATE_MVIEW_REPOBJECT
IN M.V. SITE , and i am getting following error while creating REPGROUP
CODE

I want to remove the master site which is in the multi master replication environment.
I have a doubt here. When I try to suspend the master activity,I need to give the gname.
BEGIN
DBMS_REPCAT.SUSPEND_MASTER_ACTIVITY (
gname => 'NAGADMIN');
END;
/
Where gname=master group name.But I have 9 master groups in my database. If i give one of the gname present in the master site will suspend the replication of the entire database from the replication.
eg; i am only giving NAGADMIN gname in the suspend activity script.. I have other gnames like, NAGUSER,NAGAUTH, etc....

while replicating the master site via materialized views, in mViewGroups i issued:
BEGIN
DBMS_REFRESH.MAKE (
name => 'mvadmin.hamza_refg',
list => '',
next_date => SYSDATE,
interval => 'SYSDATE + 1/1440', -- for test purpose i used such a small interval
implicit_destroy => FALSE,
rollback_seg => '',
push_deferred_rpc => TRUE,
refresh_after_errors => FALSE);
END;
in my previous attempt it worked all fine... i had a change in senerio, so i did my replication again from scractch using the same old spool in a new installation but even after 3 tries on replicating from scratch my objects are not getting refreshed automatically. even when i attempt to refresh the group it does not work. it works only when i refresh each of the participating object of the group manually.

How 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.

I have a multimaster replication between 2 sites (BASE1 and BASE3). BASE1 is the master definition site. I want to add a new master site without acquiescing the master group (named GM_ADMINISTRATEUR).
First, I have used the script provided by Oracle :
DBMS_REPCAT.SPECIFY_NEW_MASTER (
gname => 'GM_ADMINISTRATEUR',
master_list => 'BASE2.WORLD' );
and
DBMS_REPCAT.ADD_NEW_MASTERS( ....);
The first time, I had Errors, so I use the command
DBMS_REPCAT.UNDO_ADD_NEW_MASTERS_REQUEST
and I drop the master site BASE2 (connected as repadmin to BASE2 site).
The master site BASE2 is not present at BASE1 master definition site, The master repgroup is not present at BASE2 BUT, the master site BASE2 is always present at BASE3 master site. I think that the command UNDO_ADD_NEW_MASTERS_REQUEST undo the changes on BASE1 (the master definition site) but don't undo the changes on the site BASE3.
And now, when I want redo the add_new_masters, the command
DBMS_REPCAT.ADD_NEW_MASTER
return a error on the command ADD_NEW_MASTER in the DBA_REPCATALOG for the following reason:
ORA-00001: violation de contrainte unique (SYSTEM.REPCAT$_REPSCHEMA_PRIMARY)
ORA-06512: � "SYS.DBMS_REPCAT_UTL", ligne 4484
ORA-06512: � "SYS.DBMS_REPCAT_RPC", ligne 1758
And I can't continue because the new master site BASE2 does not appear at BASE1 master definition site. I think I have to drop the master site BASE2 at the master site BASE3, but I dont know how to do this.
**** Following information at BASE1 (master definition site : *****
prompt Replication schemas/ sites
Replication schemas/ sites
select
sname,
masterdef,
[code].....

I would need to create a physical standby database for DR without using data guard. I like to know in more details like
1. What would be required to switch over to standby database in case of failure of primary database? Is it going to be a manual process each time, or can be automated using scripts?
2. How the archive logs will be applied to standby database in timely manner to sync with primary database?
3. How the Primary database will be synch with Standby database once the issue resolved on primary database.
4. Where do I get a complete script to create physical standby database on Windows platform?

I want to upgrade all the Oracle 10g Release (10.2.0)master sites (bi-directional) databases to Oracle 11g Release (latest). In fact, we are using bi-directional oracle streams and snapshot replication, it means capture,propagate and apply process is running.

I have 3 sites which want to be updated as soon as the other one updates its data.(in 5 seconds). So I have chosen multi master solution,sync regardless of the resource consideration.
1-what is the difference between multimaster async and updatable materialized view regardless of resource consuming in multimaster?because in both of them each site can receive and also propagate the data...I just know that in materialized view we can work offline and then apply it manually is there any other thing?
2-I can not understand the difference between multimaster sync and async (considering the 5 seconds,because 5 second is a little time)I mean in this case are they different from each other or not.

Oracle 10gR2 on red hat.
I have an application that writes blobs via pro*c. It is running at several sites without errors for a few years now. One of the newer sites has started reporting "ora-01578 ORACLE data block corrupted".
I've tried using rman backup validate - it does not report any errors.
I've tried using rman restore and recover to correct the problem.
I've tried deleting the file with the corrupt block and using rman restore and recover to recreate it.
In any of the above cases, I do not see any errors being encountered, and when I restart the application, it works for a while and then starts reporting "ora-01578 ORACLE data block corrupted".
I've had the client do a physical check of the disk and it indicated the media was okay.
We've failed over to the standby system, so I have a wee bit of breathing room - but I'm going to be away for 4 days and will have to get back on this when I get back. I'm a little puzzled that I can fix it for a short while and then it breaks again.

Do we have any plan to create DR ( disaster site) for ORACLE 10G standard version. Since, Data Guard is not available with Standard version, can we have any another plan for the same.

1.What are the basic things we need to analyze before we recommend the business to go for oracle Dataguard for DR setup?
2. Do you know any technology that will replicate the schema from one datacenter[one primary database ] to another datacenter [secondary or replication database]?
3. What are the various option to configure the disaster recovery plan at schema level?

I am new to Oracle and a beginner in Data Guard.
1) How to find archive log gap from Primary Database site?
2) Do I need the DB_UNIQUE_NAME when setting the LOG_ARCHIVE_DEST_2 ? What is the purpose of DB_UNIQUE_NAME in LOG_ARCHIVE_DEST parameter?
3) If archivelog gap happens standby db goes out of sync with the primary database. What does out of sync actually mean?
4) Primary DB knows where to transport redo data based on the location mentioned in LOG_ARCHIVE_DEST_n of Primary DB. Am I correct in my understanding?

We have an Oracle application 12.1.1 running with oracle database 10.2.0.4 and we're using HP-UX itanium 11i v3 servers for both application and database, our requirement is to establish a Disaster Recovery site out of our building to ensure data protection.
What is the best option we can use to reduce the cost and to implement the DR site? can we use data guard ? and will be the configurations and requirements for it?

i want to ask, that in a master detail form, when a user enters few records in detail block against a master record, then when creating a new master record the form builder prompts to save the form first (with yes, no, cancel) option, if we hit no, the records in the detail block are washed away (while the master records remains)
is there any option that i can create several master records having associated detail records before saving them all at the end.

We 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?

I 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.

Submitting transaction / master data through API without exposing DB credentials...I am developing a scenario where I will submit transaction / master data like sales order / master item to Oracle apps (EBS) through MS Excel via API / interface table but like to provide only apps (EBS) user credentials rather then DB credentials so DB password could not expose to normal end user.

I have a master - details block relation where I have to display all the records in the details block based on the selection criteria made in the master block. Earlier we didn't have any selection criteria and hence used to do a execute_query behind the detail block to just retrieve all the records.
But now the master block contains fields where I can input the selection criteria and once I hit the find button it will retrieve the records based on those criteria and display in the detail block.

I got the following scenario.
- A Master/Detail form which is called from previously saved table.
- In the detail form, user is allowed to insert list of data from other block into the current detail form. For that I have one when_button_pressed with the following script define :-
Begin
go_block('ACT_VW_QT_ACTV'); <----- query block
FIRST_RECORD;
IF :BLOCK44.ITEM45 IS NOT NULL THEN
:BLOCK44.ITEM45:=:BLOCK44.ITEM45|| ' OR ';
END IF;
[code].......
When this is none, nothing being happened on the current block ( 'ACT_QT_TXN1'), I think it is because of the master/detail link where it always looks back the original link data. I think this is very common problem but I just can't figure out how to go about it.

Suppose, we have one main database on one side(say A) and an external system on the other side(say C). Midway, we have one more staging database(say B).Lets take, we have one record related to Bank Information both in database A and database B and the following activites are performed.
1) "Bank Name" column in database B is updated by the external system C.
When this Bank Name is updated in database B by external system C, we need to update the value of this field in database A.
2) Suppose couple of days later, the Bank phone number of the same bank record is updated in main database A and the same update needs to be reflected in staging database B.
How can we take care of both these activities of data-synchronization. What are the different approaches we can take? FYI, we are on oracle 10g rel2 and Windows OS.
