Description

   The CACHE/REBUILD utility creates a new, synchronized queue cache
   database. Although the new database will inherit the ownership
   and file protections of the previous database, it is a good idea
   to check afterwards that the new queue cache is owned by the same
   UIC as the QUEUE.DIR and LOG.DIR files in the PMDF_ROOT:[000000]
   directory and that the file is protected against group and world
   access (S:RWED,O:RWED,G,W).

   Rebuilding the queue cache database with this command should
   only be performed as a last resort, e.g., if disk problems
   have corrupted your queue cache database, as it will cause loss
   of some information from the queue cache database. (The sort
   of information lost includes, but is not limited to, message
   creation dates, message deferral dates, message expiration dates,
   and the original message owner information used by the PMDF QM
   utility to allow users to bounce their own messages.)

   The command PMDF CACHE/CLOSE should be issued immediately after
   building the new queue cache so as to ensure that any detached
   processes close any I/O channels to the old database and open new
   channels to the new database.

   The queue cache database is the file pointed at by the PMDF_
   QUEUE_CACHE_DATABASE logical. Normally, this is the file QUEUE_
   CACHE.DAT in the PMDF_TABLE: directory. This file should be
   protected against world and group access and be owned by the same
   UIC as the directory files QUEUE.DIR and LOG.DIR in the PMDF_
   ROOT: directory.
