RE: Migration Project: MSSQL to Oracle

The gateway for SQL Server is not free, that stinks! Now the question is, will the utilization of a gateway be picked up in the database under DBA_FEATURE_USAGE (something like that) view. I know that Oracle has started using the feature usage views to track how many times a feature is used. If it is tracked, then gateways cannot be used to solve the problem of a free migration tool. Does anyone know if the migration workbench is free? I found this related to migrating SQL Server with the migration workbench in SQL Developer
(http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/hol08/sqldev_m igration/mssqlserver/migrate_microsoft_sqlserver_otn.htm); however, it doesn’t show a cost, if any, for the workbench.

Based on experience and verified by
http://www.oracle.com/us/corporate/pricing/technology-price-list-070617.pdf, Oracle's price list, the "Transparent Gateways" are licensed and have a price tag.

The Heterogeneous Services (Formerly Transparent Gateway for OBDC, and now Database Gateway for ODBC) is included in the DB license according to http://docs.oracle.com/cd/E16655_01/license.121/e17614/editions.htm#DBLIC125 and
http://docs.oracle.com/cd/E11882_01/license.112/e47877/editions.htm#DBLIC123

Decent information on config and use at
http://docs.oracle.com/cd/E16655_01/server.121/e17907/toc.htm (Oracle® Database Heterogeneous Connectivity User's Guide for 12c Release 1 (12.1))

That, plus a set of good scripts (in PL/SQL) can go a long way to helping the OP, if he's interested in learning about it.

Oracle Gateway for SQL Server is a standard part of Oracle Database, downloaded as one of the seven download files. Installation and deployment is quite easy, and I don't believe there is any additional license cost; of course you'll want to check that to be certain.

The gateway allows you to query tables in SQL Server over Oracle database links.

Hi Bobby,  

I'm not familiar with Oracle GoldenGate, and I'm not sure it is free to use it.  

The requirement is tool should be completely free.  

Thank you

Are you looking to write a tool to do the migration? Are you prohibited from using Oracle GoldenGate? There are tools that are designed to this already, please explain in more detail why you want to write a new tool.

Thanks

Hi,

Â

I have a question about migrating data from MSSQL and Oracle.

Â

I'm working on a migration project from MSSQL and Oracle.

Â

I have around 1040 tables on source (MSSQL) side, database size could be around 100-300 GB.

Â

I would have to do this operation repeatedly, so I'm thinking of creating it as a tool (command line based).

Â

Could anyone give me some guidelines on how to achieve it.

Â

• I have already created the destination schema on Oracle(Converted all SPs, Triggers, Tables, Views, Functions to pl/sql compatibility). I have to migrate data ONLY between source and destination databases.

Â

Source: MS SQL 2008 R2

Destination: Oracle11g R2

Â

I have used Oracle's SQL Developer Migration Tool, but I'm not sure if I can bundle it as part of my software, as this tool is going to be free to the community.

Â

Thank you

NikTekki
