Description

   The CACHE/CLOSE utility is used to force, cluster-wide, all
   detached PMDF processes to close any open I/O channels that they
   have to the queue cache database. This is generally done for
   two reasons: to close all channels to the file so that it can be
   modified, and to force detached processes to re-open the queue
   cache database file so as to begin using any new version of that
   database.

   Sites using the TCP/IP channel, PMDF-LAN Lotus Notes channels,
   PMDF-XGS, Jnet (BN_SLAVE), the PMDF-DIRSYNC Lotus Notes directory
   agent, or FAX receive processes will have detached PMDF processes
   which may need to close channels to the database.
