Replication :: DML From Trigger Not Propagated
Oct 6, 2009
I am a developer and have little knowledge of Advanced Replication. I came across an issue our DBAs are not able to resolve. Suppose there are 2 sites - Site1 and Site2.There are 2 replicated tables at both sides - TableA and TableB. The replication mode used is multi-master.
TableA is used to store some records. TableB is used to change the state of those records only at originating site - that is, TableB has an AFTER trigger that does an UPDATE on TableA using the primary key and site id.Now suppose we insert a record at Site1 into TableA - the record is successfully propagated to Site2. Everything is fine so far.
Then we insert a record into TableB at Site2 - the after trigger is fired but doesn't update anything because it's not the originating site. Then the record is propagated to Site1 where again an after trigger fires on TableB - this time we run an UPDATE on TableA. The problem is that this UPDATE on TableB is not propagated to Site1, we can't see this transaction in the replication queue.
My guess is that the internal trigger that's used to capture the changes ignores this DML due to DBMS_REPUTIL.FROM_REMOTE being true.

I want to set up advance replication for 3 master site (multimaster) I created 3 master site named orc1,orc2,orc3 and followed up oracle replication management of API book instruction I created 2 tables(tes1,test2) in hr schema in all 3 master site with the same data. then I created the following steps
1-CONNECT repadmin/repadmin@orc1
2-Create the master group named hr_test_repg
BEGIN
DBMS_REPCAT.CREATE_MASTER_REPGROUP(
gname => 'hr_test_repg');
END;
/
4-add tables test1 and test2 to the group
BEGIN
DBMS_REPCAT.CREATE_MASTER_REPOBJECT(
gname => 'hr_test_repg',
type => 'TABLE',
oname => 'test1',
[code]....
I could create DBMS_REPCAT.GENERATE_REPLICATION_SUPPORT for test2 but not for test1 and it produces error
RROR at line 1:
RA-23309: object hr.test1 of type TABLE exists
RA-06512: at "SYS.DBMS_SYS_ERROR", line 105
RA-06512: at "SYS.DBMS_REPCAT_MAS", line 2552

I have one 10g database in other country. I want part of their db (selected tables or tablespaces) and import that data to my 10g DB and i want keep to date this data.
I know two ways
1. Data Pump Imp/Emp via FTP, but i can't send only data that have changed (incremental), i must pumping whole selected part of database (i want only new data from their DB, but consistanse with my DB)
2. RMAN etc. or other archivisation tool, i can do incremental achivisation, but can i send files to another instances (my db) and load only that data? Can i do that with SQL*Loader?

For using replication in our production, here i am testing golden gate as replication tool. I tested all scenario in Uni direction ( source to destination). Now have to test replication with DDL support in Bi-Direction. Not getting any Doc for doing replication in Bi-direction( Two Way). If any one has done the same, then please share limitation of replication in Bi-direction through Golden Gate.

I Have configured the replication between two database's at table level. After few miniuts of successful configuration of replication between two db's at table level, I am getting the ORA-00001: unique constraint (%s_PK) violated error in dba_apply_error.
I checked constraint name,type and status on table replicated is same on both source and destination db.

I am using prebuilt MV to perform replication of about 300-400 master tables from one database to another database. I am wondering about the impacts on triggers in general replication.
IS there a general rule to enable/disable a trigger before a refresh.

Is it possible to replicate table data on real time from sql server (2005 32 bit or sql server 2000 32 bit)to oracle 10g running on linux 64 bit? If yes then what are the steps.
It will be one way replication from sql server to oracle. Which option is best sql server dts or Oracle Stream replication to replicate table data.

We have two ORACLE-Standard-Edition installations, one is installed on a machine in our production department and one is installed on an central server. We want to replicate the data from the production-DB to the central server to backup the data on tape drives.
Is this possible using the feature of standard edition?

I need to set up replication between three 10g R2 databases.There will be one main database where the data will flow into two small databases. A little bit of information will flow back from these smaller databases into the main one.
I have been asked to evaluate ODI as an option. Unfortunately I cannot use Golden Gate due to the cost.I've had a play with ODI and it looks like it's all done on a GUI where I would much prefer to be using command line scripts for setup and monitoring.
It also looks like ODI is more geared to integrating data from many different sources but I'm just going from Oracle to Oracle so don't know if it's a bit overkill.
I'm thinking of just looking at CDC which I can set up with scripts and looks to be the basis behind ODI anyway (when it comes to taking data from Oracle) - again. I may even go down the streams route that I have used before.

We have two databases A and B, both are 10g Enterprise edition and we have to replicate only one table from A to B. A is the source and B needs a read only copy. The source of A is modified by User through Oracle Forms.
A latency of 1day can be accepted though the lesser the better. The problem is that this company does not approve of DB links in any form or any tool which in the end has to create a DB link.

I need a 2-3 TB storage server group for Oracle Database. We want SAN Storage & Server for Oracle Replication, but not Microsoft Storage Server.
For example : HP DL380 G6 as a server and EMC CLariion CX4 120 as a SAN Storage etc...
We have an option, but want some others. What do you recommend for a Server & for SAN Storage (Make & Model) to use for Oracle Replication?

I'm trying to configure and run replication. I have two PC's running as Oracle servers, having both of them the same configuration:
Windows XP Pro
Oracle 11g Enterprise Edition
First server is called Oracle1, and database name is orcl1. Second server name is Oracle2 and database name is orcl2..I'm running the following
SYSTEM/oracle1
alter system set global_names=true;
alter system set job_queue_processes=100;
ALTER DATABASE RENAME global_name TO orcl1.world;
SYSTEM/oracle2
alter system set global_names=true;
alter system set job_queue_processes=100;
ALTER DATABASE RENAME global_name TO orcl2.world;
SYSTEM/oracle1
CREATE PUBLIC DATABASE LINK orcl2.world USING '(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(Host=Oracle2)(Port=1521)))(CONNECT_DATA=(SID=orcl2.world)))';
CREATE USER repadmin IDENTIFIED BY clave
DEFAULT TABLESPACE users
TEMPORARY TABLESPACE temp
QUOTA UNLIMITED ON users;
[code]...
It looks like database orcl1 can't access orcl2.

Am trying to implement Oracle Streams Replication (Using Metalink Note 733691.1).I have configured the steps, but in my alert log am getting the below error:
Check that the primary and standby are using a password file and remote_login_passwordfile is set to SHARED or EXCLUSIVE, and that the SYS password is same in the password files. returning error ORA-16191
am successfully able to connect db's both server
From 1st server
sqlplus sys@2nddb as sysdba
From 2nd server
sqlplus sys@1stdb as sysdba
while conning it is asking for password
Both DB's are created with Same Oracle sys user password. after this disabled case sensitivity , still the error persists.
