Oracle XE + Replication + Oracle 9

I need to send data from Oracle XE to Oracle 9 server.
(local database) to (corporate database)
Woh can I do this?

You need to develop custom processing for this. XE is free and does not come with replication that I know of. If you have few tables this might not e so bad.

MYSQL 55 to Oracle 11gr1 replication(oneway) - can not replicate

I have setup golden gate replication between mysql 55 and oracle 11gr1. While trying to setup the initial load, I do'nt see any data push to oracle from mysql.
What could be wrong in my setup.? has anyone tried this kind of setup? i see the the report for replicat and it says data is not replicated. while extract shows that 4 rows from table are taken for insert.

Hi Stev
I am trying to do the initial load process
On source (MYSQL 55)
database (ggtest and table test)
table test has
TEST(COL1 INT)
manager is running on default port 7809
manager parameter file is defined with (PORT 7809)
There is initial load extract (EINI01) -->
ADD EXTRACT EINI01
param file
EXTRACT EINI01

Database in archive log mode, with minimum supplemental logging.
replicat process

SETENV (NLS_LANG="AMERICAN_AMERICA.WE8MSWIN1252")
MAP ggtest.TEST , TARGET GGTEST.TEST;
-- to start the initial load ( mysql side has 4 rows, oracle has no row )
on source, i ran the command
ggsci> start extract eini01
I can see on report, extract has picked 4 rows for insert, but on replicat side no replication done. No error reported in gserr.log and there was a communication between source side of extract with traget side manager and sunsequently repliacat on target was started by manager and stopped normally. but no rows replicated.
Between oracle-to-oracle there is no problem. But my actual project is to setup from mysql to oracle (one way replication).
let me know if you need any other info.
Thanks

Oracle Replication

Dear Sirs,
Where can i find information on how to setup database replication ?. My client requires database replication between his head office and two factories which are all situated about 20kms apart. The connectivity at present is by means of ISDN dialup, between all these locations, and they don't intent to be online 24 hrs.
The servers are all running Redhat Linux 6.2 with Oracle Standard Edition Database (Release 8.1.5).
The requirement for example is like; The purchase order entered in head office db will have to be updated on the db's present in the factories, and the goods receipt notes entered in the factory db's will have to be updated in the head office db.
Please help.
Regards,
R M Saji

We have taken ping output and sometimes its response time goes beyond 600. But we have not seen any broken job. We have four groups which contains updateable and read only snapshot and its refresh times duration is one minute, ten minutes and thirty mintues. Despite of poor connectivity at somtimes , there is no broken jobs. What could be reason.

Oracle 8i to MS SQL Server replication

Im new to Oracle, but a MS SQL Server DBA. Im helping in the architecture of a data warehouse that pulls from some disparate sources, including Oracle 8i, into a SQL Server 2000 box. We could use batch processing to pull updated data from the Oracle database to populate our data warehouse, but we were hoping to get real-time transactional processing via some replication scenario. My terminology may be wrong from the Oracle perspective, but I think the transactional replication that SQL Server supports is called synchronous replication in Oracle. My question is, does anybody know how to do synchronous replication from an Oracle server to a SQL Server? Or perhaps which Oracle product supports it? Thanks!
null

===========================================================
I'm working on the similar requirements, exactly my source DB is DB2, and the target DB is Oracle. I have two year experience with Oracle, but I know nothing about DB2. There a about 50 tables in source DB. Transactions on source DB is not too heavy(less than 10/Second), and the mainfram are all powerful.
I've though about Oracle Gateway, but I'd rather save it as the backup solution. For one thing, neither co-workers nor I have experience with it. Second, I'm afraid the Gateway performance would not be satisfactory. Furthermore, words has it that we should pay for the Gateway. So My ideas to real-time replication of the two DB is as following:
(1) use trigger in DB2 to reponse to immediate transactions in source DB;
(2) use Embedded C/SQL to extract those transactions into flat files;
(3) FTP files to the target server;
(4) On target server, SHELL scripts read the files and call Pro*C to apply the transactions into Oracle DB.
but, some problems really get me.
A: in step(1) and (2), How to set EC to do its work in reponse to trigger? I know that one can call host script in Oracle trigger, but I have no idea about DB2 trigger. Maybe, I can create a real-time monitoring EC process to address it. what's your opinion?
B: I should maintain all transaction metadata by myself. e.g. INSERT, UPDATE old/new data, DELETE info. It is originally covered by the database, and it isn't easy to handle it squarely.
C: How to address some exception? like database rollback, the process recovery in case of any interruptions in the above steps.
Could you share me some idea, Thank you!

Question on replication in Oracle 10G Release 2

Good day,
I have a few questions on setting up replication that fits my scenario described below. Thank you in advance for reading and answering my post.
Scenario
I need to replicate 100-200 tables from the first OLTP server to the second DSS server that is read-only. The servers are physically located in different countries. Both servers use Oracle 10G Release 2. Required frequency of refreshes is 1-3 hours.
Questions
1. Is it optimal to use materialized views with fast/force refreshes for implementation of this scenario? If no, what are the better options?
2. How do network interruptions and latency affect stability of work of replication with materialized views?
3. How big is additional performance overhead at OLTP (source) server due to setting up replication with materialized views?

1) I guess it depends on how you define "optimal". It's certainly a reasonable option. You might also look at Streams or even logical standby databases. There are various trade-offs involved, so it really depends on your environment.
2) What does "stability of work of replication" mean, exactly? Obviously, if the network fails, the replication job(s) will generate errors. Depending on how you set things up, the replication process will be retried after increasing intervals until it succeeds.
3) Maintaining materialized view logs on the OLTP system could certainly impact performance-- the logs have to be maintained synchronously with the OLTP transactions. That may or may not noticably impact OLTP transaction performance-- it's probably roughly equivalent to putting a trigger on each of the 100-200 tables. Something like Streams is designed to put less load on the source system because changes are captured asynchronously.

Query regarding replication process in oracle 8i

While replicating the master database I need some data. For that I stopped the replication process but in that time the application using the master database was not able to modify the database content because stopping of replication process put the master definition in read only mode.
So my query is Does oracle 8i puts the master definition site in read only mode if someone stops the replication ? If yes then is there any way to avoid this?
Thanks

Hi
First of all why you are using so much old version (oracle 8i).
when we have synchronous oracle database replication (multi master replication) then before saving our transaction at source site it will communication at all the oracle database server by using database link if at one site it find any link breakage then it will not save transaction at the source site and that transaction will ber rollback. ( Mean in synchronous replication your database link will be up any all time. This method is used where there are heavy network resource or they have replication on LAN.
In Relication 90% people use Asynchronous replication
In asynchronous replication if database link become down then our transaction become pending in the queue when link become resoted then transaction are pushed one by one in the fifo (First in First our).to their destination site to all other master or master definition sites.
Second
When we stopp replication there are two methods to stop the replication
Method A is quised the replication group at master definition site. When you quised replication group then your all tables present in that replication becomes read only you can not perform DML statment on that tables at all sites. and it is only perform by DBA to perform some administration activities like include new table in a group or regererate replication support of existing tables.or add new replication site.
Method B we totally sotpped replication that now our this server will not be in replication further. for this we use store procedure. like this
connect repadmin/repadmin@hr
SQL> Execute DBMS_REPUTIL.REPLICATION_OFF;
PL/SQL procedure successfully completed.
If you wants to again continue replication at that server. after connection wtih replication administrator apply the following command
SQL> Execute DBMS_REPUTIL.REPLICATION_ON;
PL/SQL procedure successfully completed.
For further problem you can contact me any time

Replication between Oracle Server and MS SQL Server

Hello,
Does anybody know of a well known or reliable software that can do data replication between Oracle Server and Microsoft SQL server.
I suppose I can write my own version using Heterogenous Services in Oracle but I would like to know if such an automated replication between Oracle and SQL is available commercially.
Thank you.

It could be very interesting.Sorry Viacheslav, even I couldn't find anything for the same. I am not sure that it can be done or not, I haven't heard anyone in my contact doing so. The only place where I have seen Streams being used around me is within Oracle db only. May be someone else can help if he/she has done it.

Taking snapshot of oracle tables to sql server using transactional replication is taking a long time

Hi All,
I am trying to replicate around 200 oracle tables onto sql server using transaction replication and it taking a long time i.e the initial snapshot is taking more than 24 hrs and it still going on.
Is there any way to replicate those these tables faster?
Kindly help me out..
Thanks

Hi,
According to the description, I know the replication is working fine. But it is very slow.
1. Check the CPU usage on Oracle publisher and SQL Server. This issue may due to slow client processing (Oracle performance) or Network performance issues.
2. Based on SQL Server 2008 Books Online ‘Performance Tuning for Oracle Publishers’ (http://msdn.microsoft.com/en-us/library/ms151179(SQL.100).aspx). You can enable the transaction
job set and follow the instructions based on
http://msdn.microsoft.com/en-us/library/ms147884(v=sql.100).aspx.
2. You can enable replication agent logging to check the replication behavior. You may follow these steps to collect them:
To enable Distribution Agent verbose logging. Please follow these steps:
a. Open SQL Server Agent on the distribution server.
b. Under Jobs folder, find out the Distribution Agent.
c. Right click the job and choose Properties.
d. Select Steps tap, it should be like this:
e. Click Run agent and click Edit button, add following scripts by the end of scripts in the command box:
-Output C:\Temp\OUTPUTFILE.txt -Outputverboselevel 2
f. Exit the dialogs

Query related to replication method supported by ORACLE in 10g...

Hi All,
I have few question related to ORACLE replication methods. I have two database on different machine and I want to copy at schema level from source to target database.
for this I have few queries related to Replication method as stated below:
1- I have two option one is Materailized view and another is Stream.
2- if I go for Materialized view then what it's advantage in compare to Stream?
3- if I go for Stream replication then what it's benefits?
4- For stream replication I have read that its require to set "global_names=true", with out this can we able to setup stream replication?
Please suggest me optimal solution.
Thanks....

Hello,
4- For stream replication I have read that its require to set "global_names=true", with out this can we able to setup stream replication?Anyway, when you manage Distributed Database, it's always recommended to set global_names=true. By that way you enforce that a dblink has same name as the DB it connects to.
Else about Stream the both (Source and Target) databases should be in Archivelog mode.
More over, Stream Replication allow to replicate DDL change (for instance you add a column on a Table), and have much more features than Materalized Views. If you want to share datas among several databases, Stream is an interesting technology.
Materialized view is more suitable on DSS database.
Hope this help.
Best regards,

GoldenGate - Oracle to MSSQL - handling DDL replication abends on replicat

Sorry for the cross-post. I clearly failed to actually read the "there's a GoldenGate forum" sticky...
Hello -
Very much a GoldenGate noob here, so please excuse me if I fumble on the terms / explanations - still learning.
We've recently been lucky enough to have a GoldenGate pump put into our campus environment to support our data warehouse. We don't manage the pump or source systems - just the target.
Pump: GoldenGate 11.1.1.1
Source: Oracle 11g
Target: MSSQL 2008R2
~5,000 tables of hugely varying sizes
The extract is apparently configured to push DDL changes, which is clearly not going to work with a MSSQL 2008 R2 target. We're getting abend messages on the replicat and I'd like to know if we can bypass them on the replicat or need to ask that the extract process be modified to exclude DDL operations.
The replicat error logs show exception:
OGG-00453: DDL Replication is not supported for this database
On the replicat I've tried including:
DDL EXCLUDE ALL
DDLERROR DEFAULT DISCARD (or DDLERROR DEFAULT IGNORE - neither let the process continue)
The replicat just abends with the same OGG-00453 exception.
My question: Can I gracefully handle these abends on the replicat? Or do I need to request the extract be updated with "DDL EXCLUDE ALL." Ideally, we can handle this on the replicat - I'm trying to be considerate of the main GoldenGate admin's time and also avoid any disruption of the extract.
Any direction / info / ideas much appreciated.
Thank you,
Eric

Why dont you try specifying the error like:
DDLERROR <error> IGNORE

ONLINE DATA REPLICATION ONE DATABASE TO ANOTHER IN ORACLE 9.2.0.1

I have used Oracle 9.2.0.1 version. I have created two database(ORCL, ORCL2).
in my PC. I have created INV user in both database. Currenly I have worked on INV user which is in ORCL database. Is there any technique in Oracle 9.2.0.1 online data replication from One database to another. i.e. If at any point of time my ORCL database is damaged my INV user has been recovered in ORCL2 database.

Oracle Text and Replication

We need to use an Oracle Text index on an application table in a read-only materialised-view replicated environment. The Oracle Text index needs to exist at both the master site and the materialised-view site.
We see two possible alternatives:
(1) Replicate read-only copies of the Oracle Text Index tables and indexes to the materialised view site, in addition to replication of the application table.
or
(2) Replicate only the master application table and create local instances of the Oracle Text index at both the master and materialised view sites.
Which method is best? Any experience, advice or references that you can provide would be much appreciated.
Many thanks for your help,
Peter

there is a parameter for enabling the compatibility for 8.0 to

Oracle 8i or 9i Lite Replication

Hello. We are evaluating the use of 8i or 9i Lite in an enterprise environment. The plan is to build an application that runs on a Tablet PC (Windows 98 with pen OS), collect data in the local 8i Lite DB, connect to a phone line, and use replication to synchronize records on the Tablets with records in a master Oracle 8i data base. Is anyone out there doing something similar, or has exp replicating the 8i Lite DB?

I have, the problem is that my program successfully replicates and crashes upon completion of replication, but so does oracle 8 navigator.
