This property affects dynamic statement cache matching. These clients are downloadable for free at http: A good technique is to search above and below this exception to get a sense of what is going on in the actual application.

Udn useCachedCursor to false if PreparedStatement objects access tables whose column types or lengths change between executions of those PreparedStatement objects. This new driver offers many advantages and improvements that make it the optimal choice for application development.

NONE Indicates that no materialized query tables will be considered. In the Type 4 driver, our connection URL takes the form jdbc: With respect to the drivers, J2EE specifies simple transaction management.

Under the covers, this driver performs a native connect through a local DB2 client.

The data type of this property is String, and the length is 80 bytes. Set the pdqProperties property only if you are using the client optimization feature of pureQuery. Future versions of the JCC driver will make the tracing more suitable for problem diagnosis and be more problem oriented.
