Transaction Isolation Levels and the Oracle Server

The Oracle Server supports only the TRANSACTION_READ_COMMITTED and TRANSACTION_SERIALIZABLE transaction isolation levels. The default is TRANSACTION_READ_COMMITTED. Use the following methods of the oracle.jdbc.driver.OracleConnection class to get and set the level:

• getTransactionIsolation(): gets this connection's current transaction isolation level.

• setTransactionIsolation(): changes the transaction isolation level using one of the TRANSACTION_* values.
