I have a requirement to get the data from Oracle database to Sql Database using the SSIS.
I am using sql Server 2012 Standard Edition 64 bit and oracle is 11g.
You should try and use the SSIS Connectors for Oracle (produced by Attunity). They are freely downloadable from Microsoft here. The SSIS Connectors provide optimal performance when selecting data from an Oracle db. In addition you need to setup the tnsnames.ora file with the correct connection configuration.
