change ulimit

[castro_2]

I do a ulimit -a for a user Oracle. I want to change to unlimited the data, stack, coredump and nofiles parameters.

ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 966852
stack(kbytes) 24576
memory(kbytes) unlimited
coredump(blocks) 4194303
nofiles(descriptors) 1536

Thanks

ulimit -d unlimited
ulimit -s unlimited

Please note that, you still can not exceed the maxdisz and maxssiz kernel values.

[A. Clay Stephenson]

A regular user can decrease these limits but cannot increase them. You will need to increaase the maxdsiz, maxssiz_64bit, maxssiz, and maxssiz_64bit kernel tunables. The _64bit values (if you are running 64-bit OS version) must be at least as large as the 32-bit versions.
