monitor home directory is not valid

  Explanation:  The directory from which the monitor was invoked
  is no longer valid.  Typically, this occurs when the monitor is
  invoked by the installation IVP procedure, which subsequently
  deletes the invocation directory.  However, this can also occur
  during day-to-day operations whenever directories are deleted.
  When the monitor home directory does not exist, the monitor is
  unable to invoke other server processes, such as the database
  recovery process ("DBR") or the AIJ Backup Server ("ABS") to
  name a few.  When the monitor home directory does not exist, the
  server processes will be unable to create temporary work files.

  User Action:  Stop the monitor, and restart it from a valid
  directory.
