Error description

  • The special registers are sent with the first SQL on a
    connection and when the commit or rollback is called after the
    first SQL the server returns the current special registers
    values effective at that point in time on a connection. The
    driver only remembers these special registers values returned
    from the server at the transaction boundary and clears any
    values that were set on the datasource property (i.e
    currentSchema). For subsequent transactions if the driver picks
    a new DB2 member it flows these remembered values first before
    flowing any new SQLs.
    
    But if an application is calling rollback as the first thing on
    a connection the server does not return any  special registers
    values back and the driver clears anything that is set as a
    property.
