Alexandre,

You should consider using a transaction-processing monitor such as BEA Tuxedo, IBM Encina, or NCR Top End in the tier above the database. These high-end tools are capable of this kind of rules-based or load-based distribution of transactions amongst different "resource managers".

Hope this helps...
