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.
