Hi all,
I’ve read some topic from this forum about ISAMDEF setup and they suggested having these entries in your ISAMDEF file.

MAXFILES = max # of open isam files
SHMSIZE = shared memory size (alternate to above 4 parms)

Note : SHMSIZE is the alternate of the following

MAXUSERS
USRFILES
MAXLOCKS
AVGLOCK

Is there any conflict or problem if I combine these entries on my ISAMDEF file?

MAXFILES = 200 max # of open isam files
MAXUSERS = 64 max # users in system
USRFILES = 10 max # open files per user
MAXLOCKS = 100 max # of simultaneous rcd locks
AVGLOCK = 64 average size (bytes) of a record lock
SHMSIZE = 65532 shared memory size (alternate to above 4 parms)


Thanks,
Mike

Hi,

There will be no 'problem' as such if you combine the settings, but the kernel will ignore the MAXUSERS, USRFILES, MAXLOCKS & AVGLOCK settings and just use the SHMSIZE setting to workout the shared memory size.

However, I would remove the redundant settings if you are going to use SHMSIZE, so that it does not confuse others in the future.
