I have a linked server setup in dev environment which is pointing to ORACLE server of a third-party. I m on sql server 2008 r2 and using BIDS 2008 for building an SSIS package which would pull data from oracle and do a look up in SQL server table to get a final extract.Now the query which pulls data from a single table from linked server is like the one below
select * from [oracle linked server ]..dbo.tablename a
left join mySQLSERVERtable b
on a.id=b.id
Note:I can execute this query on SSMS as the linked server is setup -[oracle linked server ] and I have sql oledb connection manager for dev environment already configured in my ssis package .
My questions are do I need to create a SSIS CONNECTION manager specifically for linked server in my ssis package ?
Are there any best practices which we follow when using linked servers in this context ?
I am thinking will the join suffer performance issue and what kind of exceptions I need to write when the linked server connection is broken.
