Web Logic Server Question:

The transaction isolation levels that are supported by the servlets application using the Oracle database include the BLOB fields. The web logic jDriver can be installed and used, but if due to some reason the code fails to execute then it shows an error message and also there are some levels in which the messages are divided and these are as follows:
SET TRANSACTION ISOLATION LEVEL READ COMMITTED
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
The Oracle database supports only these two levels of isolation. When used with Web logic’s drivers it throws an exception for the drivers that are unsupported. There are some drivers that ignore the attempts to be set an unsupported isolation level.
