Hi

I saw in weblogic server there are 2 types of type4 drive 1)Type 4 thin driver and another one id type 4 thin XA driver.So i want to know what is the difference between these two drivers.

Thanks

Both are type 4 (ie thin) drivers, the XA version means it supports distributed transactions ie it can join in with transactions from other databases or other transactional protocols using two phase commit (2PC)

XA database drivers are useful in EJBs since the transaction demarcation can span several types of transaction and you still need to provide an all-or-nothing guarantee.
