Hi folks,

we have production database 11.2.0.3.0 which is RAC mode & user by name PRDODTA in the Database which has several tables & develpoment database 11.2.0.3.0 which is also RAC mode & user by name CRPDTA which has several tables. so my question is here how to refresh data periodically from production to developement.
i know dblink is the way but any one could assits me the whole scripts or dbms job

i have created db link from dev DB (user crpdta) to prod (user proddta)

At Dev side
>create database link refresh
connect to proddta identified by password
using to-prod;

thanks & regards.

There are many ways depending on many parameters.
Investigate export/import, Streams, standby database...

db link is not 'the' way. It is one way of several. The best way for your specific requirements may very well be something else entirely. In addition to Michael's suggestions I'd add a periodic refresh from rman backup, using rman 'duplicate database'.

I can't as it would mean writing a 300 page book.
You have to specify in details what you need.
For instance, size and number of objects of the schema, is there another schema in the database(s), refresh frequency, synchronous/asynchronous...
