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.
I have a question about GG Sequence Replication and Triggers. My main database, which I would like to replicate on another server, is highly dependent on sequences for assigning surrogate keys to every row in every table in the application. I know that I need to add Sequence support to my source database (plus supplemental logging, etc), but I'm curious about the target database.
I do not anticipate allowing Read/Write access to this database - we are migrating from 10.2.0.4 (source) to 11.2.0.3 (target) on a new platform, and I want to keep the 11g database up-to-date with our production data until it is time to begin the actual conversion of our application. My thinking is that if I use the SUPPRESSTRIGGERS dboption in my Replicat session, this should take care of the use of the Sequences for assigning the surrogate key values, and the data should add to the tables normally without any intervention by the sequences/trigger combination. I know I will have to manually "correct" the sequences on my 11.2.0.3 database whenever I want to open this database up for use, but I have a script for this ready to go.
Also, in my source database, I am using Oracle Context indexes for generic name searching - this feature creates a number of DR$ named tables in the main application schema that I am replicating (approximately 50 of them). I am assuming that I should EXCLUDE these tables from the replication, as the context indexing should automatically update them as changes to the underlying data are applied via the replication of the indexed tables.
We have three unix servers with four databases (10gR2) containing "HP Operation Management Unix" (OMU) server messages for monitoring purpose, and we now want to transfer these data to one new database on a new server for reporting purpose.
The message table in each OMU database keeps the message row until it is "Acknowledged" or for maximum fourteen days, then it is moved to an historic table where it stays for another three days. Keeping data for only seventeen days are a performance issue.The new "Reporting database" is intended to hold messages data for the last 90 days.
I wonder which method to use to move/replicate data against the databases? Materialized view using database link, with view on top of the MVs. How to keep rows longer than the master (source) table, avoiding deletion when master row is deleted
Oracle Streams, with local capture and remote apply. How will this influence on the master database performance. There are about 10000 new messages in each OMU database every day. Is it possible having four streams connections against the reporting database ?
Or should I simply use database triggers which fires after insert and update and applies changes to the reporting database using database links ?
Actually am trying to replicate two db servers from one in hong kong and another in china. when am trying to establish the replication, am getting error 'ORA-04052: error occurred when looking up remote object' like this...
but the same way i have tried in my local network, it is working fine.i have tried schema replication through enterprise manager grid control..
what are the recommended network requirements for implementing Oracle Multi Master replication.

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.

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.

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.
I have an MV Log in my database. is there any ways to find what are the MVs associated with this MVLog, from other databases ?
View 6 Replies View RelatedCan I do replication between Oracle 10g and 11g?
The Oracle 10g running on windows xp and oracle 11g running on windows 7.
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 want to setup one way replication in oracle 10g Database.
Example: There are 2 database in two locations.DB1 and DB2.
DB1 need to get data from DB2 every one hour and update in DB1 database.
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 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'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.
Are there any recommendations to replicate oracle tables from 10.2.0.4 to 9.2.0.6 ?

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.
