Symptoms

Consider the following scenario:

  • You run an application that uses Microsoft Host Integration Server 2010.

  • A DB2 connection string is created in the application by using any of the following properties:

    • ClientAccounting

    • ClientWorkstationName

    • ClientUserID

  • You enable the connection pooling in the DB2 data provider.

  • You change the value for any of these three properties.

In this scenario, the data provider does not use a connection that is already open and that is in the connection pool. Therefore, the data provider incorrectly creates a new connection.
