  specified
   - DB_NUM_FSE_MIN has incorrect value when the database is
  HISAM.
   - When IMS Tools KB Server is not active, DB Sensor issues
  MSGBBE3215E, however, the message text does not show the reason
  clearly.

  ****************************************************************
  This APAR fixes the the following errors:
  
  1. DB_UNUSED_BYTES and DBX_UNUSED_BYTES do not contain the
   recent value.
  
   Before this APAR, DB sensor got and used a value of free
   space from online VSAM KSDS's catalog information.
   The value, however, is not reflected the latest value by SMS.
   By this APAR, DB Sensor calculates the latest value of unused
   bytes from the number of latest VSAM records.
  
  2. DB_NUM_FSE_MIN and  DB_AVG_NUM_NOREUSE_FSE have incorrect
   values.
  
   Before this APAR, DB Sensor did not count correctly the number
   of free spaces that are larger than minimum length segment,
   because it made mistake in the minimum length segment
   calculation.
   BY this APAR, DB Sensor gets the minimum segment length that
   defined in the DBD and it sets the correct values to the
   DB_NUM_FSE_MIN and DB_AVG_NUM_NOREUSE_FSE.
  
  3. DB Sensor issues MSGBBE3215E.
  
   By this APAR, DB Sensor changes to issue the following message
   when the specified ITKB server is not active.
   BBE1445E THE ITKB SERVER NAME IS INCORRECT
