Our customer has a process that is exhausting a system resource. The
situation can be readily reproduced on their VAX or the AlphaServer 4100
(running OpenVMS 6.2 1-H-3), but we're having trouble identifying the
resource. The problem occurs while opening a large (260+) number of
files. RMS returns error 115020, which is:
%RMS-F-CRMP, CRMPSC system service failed to map global buffers
while opening a file. The FDL for the file (all the files were created
with the same FDL) is:

Any idea as to what is causing this CRMPSC system service failure to map
global buffers? Or who should I talk to about this challenge? I am
hoping it is something simple that I am overlooking.
One more piece of information: Four AlphaServer 4100 systems sale hinges
on finding and correcting this problem.
Thanks,
Cloyce

FILE_MONITORING yes !
This option results in a global section being created for the file
to collect statistics on any operations on the file on an on-going
basis. This option is no by default, so I presume that the customer
has a reason for deliberately requesting this option.
So each file that is created with this FDL will use 1 unit of GBLSECTIONS
(or in total for just these 260 files, 260 units). The global section
for statistics monitoring is currently only 1 page in size but it will
result in each file using 1 unit of GBLPAGES and 1 unit of GBLPAGFIL (or
for all 260 files, 260 gblpages and 260 gblpagfil). This is OVER and ABOVE
any existing applications' use of these parameters. The most likely
culprit in this case is gblsections. But their gblpagfil is so low,
it could be it as well.
There is a sequence of articles on global buffers in note 8 of
this conference. While in this case, RMS global buffers are not
being set on these files, the information on the above 3 sysgen
parameters is very relevant. Article 8.4, for example, gives you
a step-by-step example on how to find out how many units of these
3 parameters are currently in use on a running system. These parameters
are cheap, so don't try to calculate precisely how many are needed.
Since correcting the problem requires a reboot of the system (and autogen
advised), if that can't be done until later, a quick workaround to the problem
would be to change the FILE_MONITORING line in the FDL file to
"no" (assuming all the creates are working off the FDL file). If it requires
editing 260 FDL files, I suspect they will want to wait until they can reboot
the system.
