IMAGECNT  takes trace of real usage of known images (images explicitly

installed with INSTALL utility) on your  OpenVMS  system,  since  last

bootstrap.





Using it on a regular basis, you can know exactly WHAT images are used

and what are not; for each shared image, you  can  know  if it's  used

enough, or if installing it /shared is only a waste of memory.





3 parameters are allowed:



 P1 - output file name

 P2 - option. "NOASK" for non-interactive mode.

              Default: interactive mode.

 P3 - minimum system uptime (days).

              Default: no minimum uptime.



You    can   use   IMAGECNT.COM   interactively   or   (better)   in a

non-interactive mode.





                             INTERACTIVE MODE





Some valid example:



@IMAGECNT                  ! output occurs on sys$output

@IMAGECNT output-file      ! output occurs on 'output-file'



When used in interactive mode, Imagecnt also asks if you want a SORTED

or UNSORTED output (based on the "used" counter field).





                            NON-INTERACTIVE MODE



@IMAGECNT output-file "NOASK"    ! output on outpu-file, SORTED

@IMAGECNT output-file "NOASK" 3  ! the same, but no action if system

                                 ! uptime is less of 3 days



When  used in non-interactive mode, you MUST give an output file name.

Anyway you can use something like: @IMAGECNT TT: "NOASK" to get output

on your screen (doesn't work in batch queues of course).



Output is ALWAYS sorted.



Execution  is  always with "SET NOVERIFY" on (useful when running into

batch queues).





                                 TYPICAL USE



My  "typical"  use of IMAGECNT is into SYSHUTDOWN.COM: executing it at

every shutdown and recording results  in  a  proper  file,  I  have  a

complete  log of images utilization. So I can find useful information,

e.g. when I wonder if a given software product is really  used  by  my

users  or  not.  (If  I've  proofs  that  a product is never used... I

uninstall it :)



For example you can include this command into your Syshutdown:



   @[...wherever_imagecnt.com_is...]IMAGECNT IMAGEUSE.DAT "NOASK" 3



and  you'll  get a new IMAGEUSE.DAT file at every shutdown - if system

uptime is less than 3 days, no operation  occurs.  You  should  manage

IMAGEUSE.DAT files.



Or  you  can  get  my  "RUN_IMAGECNT.COM"  to  run IMAGECNT outputting

results into better file name (YYMMDD_nodename_NN.DAT).



For  more  information you can write directly to the me; this software

is FREE, but of course any donation would be accepted... :)
