Bug #: 50000560 (SQL Hotfix)
Consider the following scenario. You use the Microsoft .NET Framework Data Provider for Oracle in the Microsoft .NET Framework 2.0 to connect to a data source in an application. Then, an exception occurs in the OracleConnection class in the System.Data.OracleClient namespace. In this scenario, the connection is not discarded from the connection pool.
This problem occurs because one of the following conditions is true:
  • The .NET Framework Data Provider for Oracle does not correctly recognize the exception in the OracleConnection class.
  • The provider recognizes the exception. However, a problem in the provider causes the provider to let the connection remain in the connection pool.
