  DB2 10 for z/OS was enhanced to provide detail statistics
  related to a location that was either a client to the
  subsystem or a server of the subsystem.  To manage these
  statistics, a control block is acquired to hold the
  statistical values and its pointer is stored in the relevant
  location control block.  Since multiple connections can be in
  existence to or from a location, the creation and visibility
  of the control block which holds the statistical values must
  be correctly synchronized to prevent the reported failure.
  The reported failure is an indication that the location
  control block of the current connection did not have a
  pointer to the statistics control block.
  

Problem conclusion

• DB2 has been changed to ensure that a location control
  block is correctly setup with a pointer to its statistics
  control block prior to the location control block being
  made visible to all tasks in the subsystem.
