I am using a massive Oracle db in SSIS and am trying to figure out the best way to increase performance in moving data from this db to sql server. As far as Oracle sources, which seem to have the best performance?
Thanks,
AdrianWhat did you mean by the 'Oracle sources'? We tried using OLEDB for oracle and the performance is really poor.|||I've had that experience as well with OLEDB. What I meant by sources is either the .NET OracleClient, Microsoft OLEDB provider for Oracle, or Oracle provider for OLEDB. I believe these are the only 3 options to connect to Oracle. I can't even use the Oracle provider for OLEDB without numerous errors, and have found that the other 2 are quite slow as well. So I was just wondering what other people's experiences were, and if they found 1 to be superior over another. And maybe some input from the SSIS developers as to what their suggestions are.
Thanks,
Adrian|||The OLEDB providers for Oracle that are currently available aren't terribly fast. Have you considered replicating (a subset of) your data to SQL Server from Oracle before (or at the beginning of) your package execution? This topic in BOL is probably where to start: ms-help://MS.SQLCC.v9/MS.SQLSVR.v9.en/rpldata9/html/2e013259-0022-4897-a08d-5f8deb880fa8.htm|||Hello,
We have built a super fast connector for Oracle for SSIS. We have been able to achieve about 30 times performance improvements over the OLEDB Oracle provider. E.g 1 million rows, we loaded in about 2:20 mins. Let me know if you are interested in beta bits.
