With informatica you are only refreshing the underlying SQL 2005 tables?
Do you have the updated version of informatica?
SQL 2005 cubes don't care how the underlying tables got updated.
Can you kick off a SQL agent job from informatica?
If yes, you can have informatica initiate an SSIS package job for cube processing.
Otherwise you can schedule the job with SQL agent.
