New in SQL Server 2012 is a Change Data Capture for Oracle by Attunity which allows you to continually copy data from Oracle to SQL Server.
<< Back to Microsoft SQL Server 2012 Change Data Capture for Oracle by Attunity Topics
This feature is helpful in two common business scenarios:
1. Migrating from Oracle database to SQL Server 2012 systems - you can synchronize criticial tables throughout the migration timeframe by copying changes made to the Oracle tables into the SQL Server 2012 tables.
2. Data Warehousing using a SQL Server 2012 system. Changes can be capture from your Oracle database and sent to SQL Server 2012 databases to keep the data warehouse in sync. Build the data warehouse in SQL Server once based on origin data
from Oracle, and keep it up to date as the records change. Meet real time OLAP needs.
Note that there are 32-bit and 64-bit available. You should favor x64 bit if you have a 64-bit server where you are installing the CDC Instance. The Oracle Client installation bitness should match the Attunity bitness to
This table explains which features are needed to successfully use CDC for Oracle by Attunity.
Service Platform to run CDC services to pull from Oracle and write to SQL change tables. Administer through MMC Snapin.
Client Platform to administer CDC designs through MMC Snapin.
Oracle Client Drivers
Oracle Download Center
Providers needed to communicate with Oracle log miner. Make sure that the 64 or 32-bitness of the Oracle client download that you choose matches the same bitness of the Attunity MSI that you choose. Only Oracle Call Interface (OCI) is required on the CDC
Instance computer, but you may choose other options to help troubleshooting efforts as needed.
SSIS Components (runtimes)
SQL Server 2012 Setup > Shared Features > Integration Services
SQL Server Integration Services runtimes include the necessary tasks, connection manager, and dataflow components to run SSIS packages with CDC components.
SSIS Components (design time)
SQL Server 2012 Setup > Shared Features > SQL Server Data Tools
For SSIS Developers, they may want to develop SSIS packages that utilize the CDC components on a client workstation. Therefore, Attunity CDC components are included with the SQL Server Data Tools (formerly Business Intelligence Development Studio) when it
is installed on a client workstation for example.
SQL Server Management Studio
