Could anybody point me in the right direction for setting the kernel parameter, max_stack_depth, to 10240 for database tuning?
I have currently set it by running 'ulimit -s 10240' but this does not survive a reboot.
Thanks for the response, I've been nosing around that file recently but noted the first two lines;
#This file sets the resource limits for the users logged in via PAM. #It does not affect resource limits of the system services.
Look at the file /etc/security/limits.conf
I added these two lines to the end of the file
soft stack 12288hard stack 12288in an attempt to set the stack depth to 12MB so that I can configure postgresql max_stack_depth = 10MB.
I rebooted, ulimit -s shows 12288.
When I restart my service (#It does not affect resource limits of the system services.) becomes apparent.
<snip> Well, a quick and dirty hack would be to add that as a script in /etc/rd.local (or whatever the appropriate place is for CentOS 7).
