SCD does not show OLEDB Connections to ORACLE database
SCD does not show OLEDB Connections to ORACLE database
- When I use the SCD wizard the Connection Manager dialog only shows me OLE DB connections against SQL Server databases. I have an Oracle connection using ORACLE provider for ORACLE but this is not shown in the dropdown. why,how to solve this?

- The Slowly Changing Dimension Wizard only supports connections to SQL Server.

Alternatively you can use lookup transformation for SCD purpose. Follow as below,
1. Create a Oracle source.
2. place a lookup tranformation and select records from the destination table
3. Place a condition split and split the records based on the lookup output. (Matched record means data already exists and update required. Unmatched records means new records and need to insert).
4. On the unmatched path of the condition split place a ole db destination and insert the records to the destination table.
5. on the matched path place a oledb command tasks and write an update to update the records.

There is weakness mentioned in the link "Memory consumption for this component is larger, as it's not doing row-by-row lookups." Keep this in mind and decide on whether to go for this or not.
The steps mentioned in my earlier post is a workaround when you use other datasources as source or when the number of records needs to be processed by SCD is more.
