We deadlocked anyway with these settings. We now run with:
LTXHWM 40 # Long TX high-water mark (percent)
LTXEHWM 65 # Long TX exclusive high-water mark (percent)
and Informix will never convince me that it's safe to run with them any
higher.
10. Start out with LARGE but relatively few logfiles if you expect your
system will grow over time (or even if you don't expect it to, it will
grow anyway). Later you can add logfiles (up to the max of 61). If you
instead start with a lot of relatively small logs you will be stuck at
the max log limit of 61 and won't be able to change their size (LOGSIZE)
without reinitializing your disc space.
