Simple Replication on Oracle 8 !

Dear,
I have 2 same database : try1, try2. They reside on 2 different computers.
Try1 is on master site.
Try2 is on snapshot site.
Try1 has one table A
Try2 has one table A, and one snapshot K.
CREATE SNAPSHOT K
AS SELECT *
FROM A@Try1;
When table A in try1 database update any data, the snapshot K in try2 database will receive the new update.
I want use data in snapshot K to update data in A table of try2 database. What function or stored procedure or tool I do ?
Thanks !

I got exactly the same problem !!
Any suggestions ???

How to implement simple replication with Oracle 8.0.5 ?

Hello,
I want to replicate some tables of my database's tables with simple replication :
I use local naming configuration.
Both databases have the same default ID ORCL.
But every time I create a database link and I want to test it, I receive the message : "The link is not active!".
So, if some DBA could help me, I will be very grateful.
Thank you.

Hi,
In our project we are using this type. Since in this project server in UNIX(DEC) and client is running on windows. We have created a listener which always listen requests from client and doing the according to the request.
Step1. create a request table, where u are inserting ur request.
step2. create PRO*C proram, which is listening request on the table. If there is any request, call the imp (executable). This is happening on server side.
Benifit. U can make a request from cleint and ftp the file client sit.
Are u interested in more details and code, pls send a mail to me

GoldenGate Replication or Oracle 11g Streams?

We are working with a customer that is interested in implementing Oracle 11g Streams.
I don’t know the GoldenGate products and
I am not real familiar with streams other then hearing it can be tough to tune and if something goes wrong, it can be a pain to get right..
They recently heard of Oracle’s purchase or GoldenGate and became interested when they read that the company may offer possibly a simpler replication strategy then streams as far as setup, tuning, maintainin, etc..
Has anyone heard of what Oracle’s future plans/direction are for integrating GoldenGate into their fold, specifically the replication side like streams?
Thanks

I predict that in the future the GoldenGate Oracle users are going to get the short end of the stick now that Oracle has purchased them. I do not believe that Oracle purchased GoldenGate for their Oracle to Oracle capabilities. I assume that they wanted to acquire their ability to replicate from non-Oracle databases.
There is nothing inherently wrong (design-wise) that makes the Oracle Streams product inferior to GoldenGate or Quest's Shareplex product. But both companies have continued to sell their products (which are not cheap) against a product which basically free.
Why is this? Do you think that Oracle does not have the technical capabilities to build a great replication solution? If Oracle was interested in making a great Oracle to Oracle replication product, they could have invested a small fraction of the amount they paid for GoldenGate and added the necessary resources to build the best replication product on the market. But the don't because that is not what they are interested in doing.
There are a couple of press releases that Oracle put out about the GoldenGate acquisition and one of the advantages they claim GoldenGate will benefit from is their $30 Billion dollar R&D budget. But why didn't Oracle use some of that 30 billion to make Streams a great product??
Oracle purchased GG for reasons that have nothing to do with Oracle to Oracle replication. Future resources and priorities will go towards those goals.

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.

Sorry, Aman,
I couldn't find any info about replication to MS SQL. Is it possible at all? Could you provide link where we can read about this? 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.

Implementing replication in Oracle 10&11 Standard Edition

I am implementing an oracle based application which will run under Linux/Oracle 10gr2 standard edition and which will soon be upgraded to Oracle 11g standard edition.
One of the requirements of the application is that a hot standby must be provided. To provide the hot standby, I must implement some sort of replication mechanism, but the nice replication features (data guard, streams, advanced replication, basic replication) are only available with Oracle enterprise edition.
Two questions:
1. It appears that I will be building a home-made replication mechanisms. I am planning on using insert/update/delete triggers and dblinks to trap database updates and propogate them to the standby server. (alternatively, may write them to files as SQL statements and have the second server load the files). Is their a better way to implement replication in Oracle SE. (esp. a feature of Oracle SE that I could be using to do this?).
2. Oracle Advanced and Basic Replication are not shown in the Oracle 11 Editions Description web page which lists the availability of features across the various oracle versions. I assume it is still supported in Oracle 11, but is Oracle Streams now the "best practice" for implementing replication (i.e. instead of advanced replication?)
Thanks in advance,
Werner

1) Having database triggers that use a database link is an exceptionally poor way of implementing a hot standby. If the database link goes down, or if the remote database is unavailable, the trigger will generate an exception and the parent transaction will be rolled back. Which means that the system is available only if both databases are available and the network between them is available, which is exactly the opposite of what a hot standby would be expected to provide.
2) You most likely want to set up a manual DataGuard-like setup. Clone the database from one machine to another, keep the standby database in managed recovery mode, and copy archived log files from the primary to the standby periodically. You'll have to script that, of course, but that shouldn't be insurmountable.
3) Basic replication (one-way materialized views) are available in the standard edition, but probably aren't the sort of thing you'd want to use to build a hot standby.

REPLICATION BETWEEN ORACLE 10g and postgresql/MySQL/MSSQL SERVER??

Hi Friends.
I want to know if there are a manner of replication between ORACLE and (postgresql or mysql or mssqlserver).
Please, my email is [email protected]
Thanks
Manuel

Sure.
Are you talking about replicating data in one direction? If so, in which direction (Oracle to non-Oracle or non-Oracle to Oracle)? Or are you talking about bidirectional replication?
Which database do you want to be the "master" (i.e. initiate the push or pull of data)?
What sort of lag is acceptable? Minutes? Hours? Days?

Advance Replication and Oracle Label Security

Has anyone been able to configure both Advance Replication and Oracle Label Security to work together?

This is currently not supported in Streams. I have an enhancement request in with Oracle for this functionality. This won't be seen in 11g R2 either.
Has anyone done Label Security with Advance Replication?

TimesTen Replication with Oracle

I am generating some 100k data in TimesTen i would like to replicate those data to Oracle database.
What will happen if there is sudden crash in the system of TimesTen ,how replication will takes place ,once again i reconfigure the replication to oracle whether the data which are inserted in TimesTen will get reflected or i need to manually need to load the data,is it is possible.
If there is sudden crash then how the data at the TimesTen end will be written to the disk ,since data which are been written to disk are on the basis of check-pointing and transaction logging. if so how to avoid this situation in real time.
Thanks!

The 'replication' to Oracle (actually AWT cache group) works by capturing the changes from the TimesTen transaction logs. Once a change reaches the TT transaction logs on disk it is safe and once the TT machine, TimesTen and the replication agent are back up replication will resume from where it left off.
More generally, data stored in TimesTen is persisted and protected using the checkpointing and transaction logging mechanism within TimesTen. By default, TimesTen uses asynchronous write to the logs (DurableCommits=0). This gives very high performance but in the event of a failure you will lose the last few committed transactions. If this is not acceptabel you can tell TimesTen to use synchronous commit to disk (DurableCommits=1). This is much (and I mean hugely) slower but ensures that all committed transactions are safe (unless the disk itself fails). TimesTen also provides TimesTen to TimesTen replication (both asynchronous and synchronous) as an additional / alternative method of data protection.

Can we use replication usings oracle 10g steams for EBS r12 database?

HI,
We are using EBS 12.0.6 and database 10.2.0.3 on linux 32-bit/64-bit OS (Multi-Node env).
Actually We want to decrease the load of custom reports on actual production system, so thats why
we need reports server and as my past experience I had used oracle streams for replication with simple schema based replication and tablespace replication also.
So, please educate me, that can i used the oracle 10g streams for EBS schemas like APPS, GL ,INV, PO, ONT, ODM, AR, AP, CM etc?
Please provide us the above related env docs and road Map.
If you have any other way to create the Report Server?
Regard,
Fayaz Ahmed

Hi,
We are not in a position to upgrade the EBS from 12.0.6 to 12.1, because this is lengthy task, but we had already tested technically it in test env, but functional testing in pending.
Now we want to immediate solution if possible, because this is production?
So, please suggest another.
regards

Database replication between Oracle RAC and Oracle Standalone DB in 9i

Hi,
We have currently 4 node RAC environment and Oracle RAC implementation with 4 Oracle instances. We want to move the one instance and make it Standalone with Oracle database due to availability issue. Thus we will remain with 3 nodes on the RAC database and one Standalone database. We want to implement Oracle replication on this solution, where partial database of RAC environment needs to be replicated to Standalone node.
We will have Oracle 9i database server for both RAC and Standalone machine.
The partial data that we are looking for replication are of size 25GB. Some of questions we have:
1. Is there any other replication mechanism apart from Materilzed view for this solution?
2. Is it feasible to sychronize around 25GB data between servers?
3. What can be estimated time for refresh or Synchronization?
The methods that we are evaluating currently for this replication are:
1. Multi Master replication
2. Oracle 9i Datagaurd.
Please let me know if we need to look for some other methods of replication also.
Thanks in advance for help.

2. Is it feasible to sychronize around 25GB data between servers?Sure. Depending on the rate of change, your latency requirements, whether the standalone database has the horsepower to apply all the changes generated by to other three nodes, etc.
3. What can be estimated time for refresh or Synchronization?Depends on the architecture, the network connection, whether you are doing incremental refreshes, etc. And it depends on what time you're measuring-- you might be measuring the latency between the RAC cluster and the standalone database, you might be measuring the time it takes to incrementally refresh a single materailized view when there have been no changes, you might be measuring the time it takes to do a complete refresh of an entire refresh group, pulling 25 GB of data over the network.
The methods that we are evaluating currently for this replication are:
1. Multi Master replication
2. Oracle 9i Datagaurd.DataGuard is not an option if you only want to replicate a subset of the data. The two realistic options are materialized views and Streams. Are you anticipating that you will be making changes on both nodes? If not, you can use simple materialized views rather than multi-master replication.
Since 9.2 is not longer covered by Premier Support, are you planning to upgrade to a supported version in the near future? In particular, Streams works a lot better in later versions of the database.

I'm not sure which of the linked articles you're following, but I expect that you're making things more complicated than they need to be. Those articles discuss configuring multi-master replication, but it sounds like you only need simple materialized view replication. In that case, all you'd need to do is
1) Create a database link from the destination system to the source system
2) Create a materialized view log on the source table on the source system
3) Create a materialized view on the destination that selects all the data from the remote table and is set to be fast refreshable and to refresh every 5 minutes.
On the destination system
CREATE DATABASE LINK to_source_system
CONNECT TO username_on_source_system
IDENTIFIED BY password_on_source_system
USING 'tns_name_for_source_system_on_dest_system';On the source system
CREATE MATERIALIZED VIEW LOG
ON table_to_replicate
WITH PRIMARY KEY
INCLUDING NEW VALUES;On the destination system
CREATE MATERIALIZED VIEW table_to_replicate
REFRESH FAST
START WITH sysdate + 5/(24*60)
NEXT sysdate + 5/(24*60)
AS
SELECT * FROM table_to_replicate@to_source_systemIf you have multiple tables that you want to be replicated in a transactionally consistent manner, you can put multiple materialized views into a refresh group and schedule a refresh of the refresh group.

Simple Query in Oracle Linked Table in MS Access causes full table scan.

I am running a very simple query in MS ACCESS to a linked Oracle table as follows:
Select *
From EXPRESS_SERVICE_EVENTS --(the linked table name refers to EXPRESS.SERVICE_EVENTS)
Where performed > MyDate()
or
Select *
From EXPRESS_SERVICE_EVENTS --(the linked table name refers to EXPRESS.SERVICE_EVENTS)
Where performed > [Forms]![MyForm]![Date1]
We have over 50 machines and this query runs fine on over half of these, using an Oracle Index on the "performed" field. Running exactly the same thing on the other machines causes a full table scan, therefore ignoring the Index (all machines access the same Access DB).
Strangely, if we write the query as follows:
Select *
From EXPRESS_SERVICE_EVENTS
Where performed > #09/04/2009 08:00#
it works fast everywhere!
Any help on this 'phenominon' would be appreciated.
Things we've done:
Checked regional settings, ODBC driver settings, MS Access settings (as in Tools->Options), we have the latest XP and Office service packs, and re-linked all Access Tables on both the slow and fast machines independantly).

Primarily, thanks gdarling for your reply. This solved our problem.
Just a small note to those who may be using this thread.
Although this might not be the reason, my PC had Oracle 9iR2 installed with Administratiev Tools, where user machines had the same thing installed but using Runtime Installation. For some reason, my PC did not have 'bind date' etc. as an option in the workarounds, but user machines did have this workaround option. Strangely, although I did not have the option, my (ODBC) query was running as expected, but user queries were not.
When we set the workaround checkbox accordingly, the queries then run as expected (fast).
Once again,
Thanks
