Synchronisation of data between two databases

i have two databases having tables with same fields and i would like to transfer the data from one database to the other , how do i do that? is there any link which talks about synchronisation of data between two databases?

Make the database name same in both databases and use Veritas tools for data copy.

Transfer large data between two databases via ODI

Hi, we want to transfer our 2 billion records (70gb) A database oracle server to B database oracle server via ODI LKM SQL to Oracle (SQLLDR).We use a filter like "prod_enter_date>sysdate-1" for daily records(about 200.000).It takes about 1 our.How can we transfer data faster, thanks for your advice.

OK so assuming the Oracle DB's can see each on the network other have a word with your DBA's about creating a DBLink and test out the LKM DB Link KM.
Also try Uli's amended LKM if dont want to be too intrusive on your souce system creating synonyms etc. : http://sonra.io/tag/lkm-db-links/
I have used both and they work fine.
Basically you are currently unloading a large amount of data, transfering to another location and then uploading that data with no transformation to the target environment, a DBLink LKM will transfer this data without the need to unload / upload , just the network transfer.
Another thread here : https://forums.oracle.com/message/9630782
To re-quote the that thread quoting the documentaion for that LKM : "As it says in the component description - "This module is recommended when developing interfaces between two Oracle servers."

Technique to pass data between two databases

The other reply is about connectivity only. If you have connectivity then it isn't relevant. If you don't then you can't do anything.
So ignoring that....
>
pls tell me is how i can implements this ?...It depends on your data.
Basically you can have the following data problems
A. Add rows
B. Delete rows
C. Modify rows
You can also have two directions
1. Client to main database.
2. Client from main database.
In terms of solution.
- Decide direction.
- Add rows - use a creation time stamp. Get last update timestamp then moving anything newer.
- Delete rows. Harder than add because either you have to keep a record of deleted entries or you have to compare the entire existing set and look for holes. Once you find existing entries then delete them.
- Modify. Much harder and it depends on the data. It should also be considered whether manual verification is required. For instance can the customer address (stored in the database) be updated both on the clien and the main database? If yes then which one is right? What if the address was updated in both places and then a day later the phone number was updated? Two changes and maybe one is right in one place and one is right in the other. A replay log might help here but maybe not.

Synchronisation of Data Between 4 Database.

We are using a Customised ERP based on Oracle 8i And Developer 5i.We have Four Servers Lying to four Different Locations.For Synchronisation to Primary server.We used to export data from all locations and import it over here.Its a very Hectic Job , takes more than 2-3 Hours.Now as we want to have Consolidated Sales on Daily Basis.So is there any other means to synchronise all servers with our Primary Server.I have used the concept of materialised view too But for So much table Replication takes a long Time.
Thanks In Advance For any Reply

OK. You will need to make sure the ip addresses you assign to your vms are in the same subnet as the adapter create by the installation of vmware. Once you get the fundamental network setup fixed, you can treat these vms just like any machine in your data center. Forget the vm console and access them exactly like you would any remote server -- putty for the linux machine and Windows Remote Desktop for the Windows machine.
At a command prompt on the host, issue this:
c:> ipconfig -allYou will get back info on several net adapters, two of which are identified as being with vmware -- vmNet1 and vmNet8. Note the IP addresses of both. We'll need it later.
You will also need to know how you configured the network adapters on your vm's -- NAT, bridged, hostonly, ???
Note that these issues are out of scope for this forum. I don't mind helping, but I no longer have a vmware installation to reference details.
What have you actually tried to do? ( Data Transfer )I tried to exchange data from windows database to linux DB
That's pretty vague. Exactly how did you try to "exchange data"? A sql statement using a db_link? export/import? Carrier Pigeon?

Where are you stuck?
I don't know , how to configure ip and necessary information for windows database.
Configuring an IP address is purely an OS admin issue and is out of scope for this database forum.
Google is your friend, but only if you use it: [url http://lmgtfy.com/?q=configure+windows+ip+address]http://lmgtfy.com/?q=configure+windows+ip+address

Using XML to exchange data between different databases?

Hi,
Does anyone know of any case-studies or tutorial's where XML has been used to transfer data between different databases... i.e. oracle to sql server?
I basically looking into the differences between two schema's and what sort of tranformations need to take place.
Thanks in advance guys!

How to ...synchronization between two databases

Hi,
I want to set up automatic synchronization between two databases. For example, database DB1 and DB2 have table t1 and t2 with the same columns. If someone updates a record in table t1, I want automatically update the record in t2 or vice-versa.
How can I make an automatic system like that?

1) What is the business goal you're trying to satisfy? Failover, reporting, replication, geographic co-location, etc. each have their own set of technologies. Explaining what you're trying to accomplish from a business perspective will help us identify which technology (or technologies) to focus on.
2) Are you synchronizing a single table? Or multiple tables? Or all the tables in a schema? Or all the tables in a database?
3) Is there a stable network connection between the boxes?
4) What version of Oracle do you have (10.2, 10.1, 9.2, 9.0.1, etc)? What edition (standard, express, enterprise, etc)?
5) How quickly after a change has been made on DB1 does the change need to reflect on DB2?
6) Am I correct in understanding that you want to be able to change the same row of data on either DB1 or DB2? So the replication needs to go in both directions?

How to share the data between two or more frames

How to share the data between two or more frames based on the database relationship in JDeveloper?

You can pass data between frames by passing it as parameters.
That is when you are invoking another frame, pass your data as arguments through the constructor to that frame .
You can also achieve this through static or public methods, but static variables as we know is not suggested which might occupy more memory space.

Intervals, synchronize the data between two oracle tables located in diffe

Hi Experts,
Is there any way I can, at set intervals, synchronize the data between two oracle tables located in different servers? What is the software, if there is any? If there are steps I can follow, so much the better.
Thanks!

I'm not sure what you want to achieve here...
I want to synchronize both the Servers , so that it can update HO servers as well as Factory Server with the complete data. Could you please elaborate a little bit more; basing on your description I could also tell you how to setup timesync for those two servers if I understand "complete data" as the current date and time...
Also a lot of solutions are platform and version specific so it would help if you could indicate OS and Database Versions (4 digit).
And I still fail to see what this has to do with forms. You might want to post your question to the Database General forum: General Database Discussions
cheers

Use of SAP memory to transfer data between two different sessions.

Hello experts,
I wish to know how to use SAP memory to transfer data between two different sessions.
The scenario is that when I run a report and change a variable, the value of changed variable should be availabe to another user on another terminal.
Thanks & Regards!
Sumit

Hello,
Just to add what Max has already mentioned. IMPORT TO / EXPORT FROM DATABASE statements can be used to store data in special "cluster" tables (you can't use any DDIC table) e.g., INDX.
@OP: You can opt for Shared Memory(SHM) for this specific requirement as well. In my opinion SHM is a bit tricky to code, but it is easier to monitor. The opposite holds true for "data clusters".
You should remember SHM is app-server specific. So if you've a load balancing scenario, using SHM can cause problems.
Hope i'm clear.
BR,
Suhas

How can I share data between two forms on different lists

Using a custom content type, I created two lists that I want to share the same data - one is a calendar. Our employees complete a form from the "Out of Office Request" list that has workflow functionality that sends an email to that person's
manager. If the manager approves the request, the item automatically populates the "Out of Office Calendar." The problem is that the only information from the request list that populates the calendar is the Title field and date/time fields.
I need the manager name in order to create a view for each manager.
How can I connect the other information in the request list to the calendar list. It seems to me that if the title and date fields carry over the information, there should be a way to connect the other information. I'm using Designer.
I've tried to connect the two lists' webparts with the wizard, but when I get to the page that maps the two lists, there are no column names and the "Next >" button is grayed out. This seems like the logical place to connect the two lists,
but it isn't working.

Hi,
According to your post, my understanding is that you wanted share data between two forms on different lists.
To show external information on the calendar event, there are two methods: Calculated column, workflow. You can refer to:
A Simple Guide to Show More Information on a Calendar Event
I recommend to use workflow to achieve what you want. But you need to create a people column to display the manager.
You can create a workflow associated to the "Out of Office Request" list, add action to Start Approve Process. If the manager approves the request, you can create a item in the calendar, and then update the people column and the title column.
Then the calendar will display the Title, date/time and the manager.
To create a view for each manager, you need to modify the Filter. You can use the people column is equal to the manager name or the Title contains the manager name.
Thank you for your understanding.
Best Regards,
Linda Li

Different ways to copy data between two schemas in one instance

Hi there,
I am searching a good way to copy data between two schemas in the same instance.
Both schemas have an identical structure such as triggers, tables, views and so on. The only difference is the purpose: one is the productivity system and one is for development.
I looked at datapump but I do not explicit want to export / import. I want to keep the data in the productivity schema as well as copy it to the other schema. Any ideas? I found out there is a copy statement but I dont't know how that works.
Thank you so far,
Jörn

Thank you for your replies!
I also thought of creating a second instance for development and move the dev - schema to it. I just don't know whether our server can handle both (performance?). Anyway the idea is to have a possibility to quickly rebuild the data inside a schema without indixes or triggers, just pure data. I thought the easiest way would be to copy the data between the schemas as they are exactly the same. However if you tell me DataPunp is the best solution i won't deny using it :).
When you export data a file is created. does that also mean that the exported data is deleted inside the schema?
best regards
Jörn
Ps: Guido, you are following me, aren' t you? ;-)

How can I get extract the data between two cursors on an XY graph

How can I get extract the data between two cursors on an XY graph

Well, you say xy graph, so this might be a more complicated problem.
For a waveform graph it's trivial. Simply get the two cursor indices (property: cursor index) and apply them to array subset of the data. Is that all you need?
Here's how the above code would look like. using cursor.index instead of cursor.x elimnates the need to include scaling information.
For an xy graph, there could be multiple segments (e.g. imagine a spiral that passes the desired x range multiple times from both sides). This would neeed significantly more code for a general solution.

How to compare data between two tables?

Hi,
My team is trying to develop a SAP data migration tool (DMT) using ABAP.
One of the functionalities in the DMT is to validate the data in the staging area against the loaded SAP data.
The tables in the stagin area are customer tables (i.e. user-defined tables starting with Y, Z).
How do I compare the data in the staging area against data that are loaded into SAP tables? Are there some built-in SAP functions to do this? Or, are there some better ways of doing this (e.g. instead of comparing against data in the SAP tables, we compare with some INTERNAL tables)?
Any help would be greatly appreciated, thanks!

Hi Kian,
Use <b>SCMP</b> transaction to compare data between two tables and you can not use this for comparing internal tables.
Thanks,
Vinay

Hide values in URL, passing data between two webdynpro(ABAP) applications.

Hi
   When transferring the data between two webdynpro applications, How to hide the values in URL.
Example : First application is using for login
                Second application is for some transactional screens.
Based on first application login data second application should trigger. When passing the user id and password thru URL every one can see the user name and password at internet explorer, so how to hide that user name and password in URL.
Thanks
