Question

In my .NET 3.5 project, I have created an OracleConnection object called conn.

Then i create a Transaction object as follows :

using (OracleTransaction trans = conn.BeginTransaction(IsolationLevel.RepeatableRead))

WHen the control goes to the Transaction creation line, it gives an exception as

System.ArgumentException was unhandled
Message=”Invalid IsolationLevel
parameter: must be ReadCommitted or
Serializable.”
Source=”System.Data.OracleClient”

Has anyone faced this problem ? Why can i not set it to RepeatableRead ?

Thanks,
Chak.

Oracle only supports read commited or serializable isolation levels.
