Consider the following scenario for either SQL Server 2005 or SQL Server 2008
You design a SSIS package using Business Intelligence Development Studio (BIDS).
In your package you connect to an Oracle server using an OLEDB provider for Oracle and use either Oracle client 10G or 11G.
You use package configuration file to set all the connection properties for the Oracle connection at runtime.
In this scenario, if you execute the package from BIDS you get the following error message
"Error: 0xC0202009 at Package, Connection manager "OLEDB Provider": SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E21.
An OLE DB record is available. Source: "Microsoft OLE DB Service Components" Hresult: 0x80040E21 Description: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.".
Error: 0xC020801C at Data Flow Task, Oracle OLEDB Source : SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "OLEDB Provider" failed with error code 0xC0202009. There may be error messages posted before this with more information on why the AcquireConnection method call failed.
Error: 0xC0047017 at Data Flow Task, DTS.Pipeline: component "Oracle OLEDB Source" (1) failed validation and returned error code 0xC020801C."
This is due to the fact that the Initial Catalog property in configuration file is not recognized by the Oracle provider. Note that this is blank for the Oracle Connection manager in the configuration file.
For example, the following XML Configuration file is generated when you use BIDS to create a SSIS package that connects to an Oracle server:
