ulimit setting
I would like to increase my data and stack limit to 3.8 GB. What I did was change maxdsiz and maxdsix_64bit from 2GB to 3.8GB (old and new setting as per attached)
after restart server, I notice my data limit is as below
ulimit -aH
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 4292870144
stack(kbytes) 262144
memory(kbytes) unlimited
coredump(blocks) unlimited
nofiles(descriptors) 2048
and ulimit -aS is
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 4292870144
stack(kbytes) 262144
memory(kbytes) unlimited
coredump(blocks) 4194303
nofiles(descriptors) 2048
is it something is wrong ? I also tried to set to 3GB but I get the below error
ulimit -d 3145728
su: ulimit: The specified value exceeds the user's allowable limit.
please advise what is the problem
thanks

Re: ulimit setting
>>ulimit -d 3145728
su: ulimit: The specified value exceeds the user's allowable limit.
The system wide stack is only 256 MB and allowable maximum value for stack ulimit command is 256MB
You may need to change the system wide stack according to your requirement by changing the kernel parameters maxssize and maxssize_64bit
thanks!!

Re: ulimit setting
Can you post the "chatr
I not sure what you mean, this is my Oracle Application Server, so what should I type.
2. hi, Johnson,
is the below post is the wrong one ?
>>ulimit -d 3145728
su: ulimit: The specified value exceeds the user's allowable limit.
The system wide stack is only 256 MB and allowable maximum value for stack ulimit command is 256MB
You may need to change the system wide stack according to your requirement by changing the kernel parameters maxssize and maxssize_64bit

Re: ulimit setting
By the way ,try changing the softlimit
ulimit -Sd 3145728
>>ulimit -Hd 31400
su: ulimit: The specified value exceeds the user's allowable limit
I saw this kind of error some time ,when I tried to execute ulimit -Hd
what i did is change it with ulimit -Sd 31400
and then executed ulimit -Hd 31400
To increase the stack size you may need to tune the kernel parameters as i said in the previous post
Thanks!!
Johnson

Re: ulimit setting
The maxssiz & maxssiz_64bit are in bytes on kernel and ulimit give out put in kilobytes
can you post kmtune|grep -e "maxd" -e "maxs"
did you try to reduce it by ulimit -Sd ?
Thanks!!!

Re: ulimit setting
maxdsiz and maxdsiz_64bit to 3.5GB
and maxssiz to 400mb and maxssiz_64bit to 1GB ,
the ulimit -aH give output
data(kbytes) 4292870144
stack(kbytes) 392192
please see below for your requested info :
app:/# kmtune|grep -e "maxd" -e "maxs"
maxdsiz 3500000000 - 3500000000
maxdsiz_64bit 3500000000 - 3500000000
maxssiz 401604608 - 401604608
maxssiz_64bit 1073741824 - 1073741824
