I have a Sun machine 5.8 and would like to modify the ulimit parameter for numner of file descriptors.
the output of plimit <process name> is:
I need to increase the number of file descriptor by 512. I will insert this command on the script:
The script will look something like this:
I haven't used this command before. Will this increase the existing size to 512 or will it reduce the nofiles to 512?
I am unable to determine the nofiles using the plimit. how would I know the current settings for nofiles? so that I can know if the "ulimit -n 512" command is correct.
Also, does it have a maximum value for that one? And also the impact on the system resources as well.
I can not test this one until I am sure since I will be doing it on a live network.

Remember you may need to update /etc/system for the changes you plan on making to be persistent across reboots.
i executed the command plimit <PID>... i was expecting an output either 256, 512, 1024, etc but instead the output was 30000.... this is different.
i am afraid that if a change it using "ulimit -n 512" the 30000 will become 512... which is very small. i need your opinion about this.
please help
It will not increase, but rather will set it to 512, just tested that. For the max value of nofiles, i really dont know but you can always try "ulimit -n 30512" and let us know the result ...
hmmm... the problem is that when i tried to check the other related settings like "plimit <PID>"
it tells me that it was already at its maximum value:
i also tried to look at /etc/system and has the following value:
the question is can i still be able to set the nofiles value greater than 30000? is the setting at the /etc/system not related to the setting in the pfiles/plimit command?
I see, you still can change it (nofiles) system wide with root, i did mine just like that
but if the limit is still 30000 on yours then I suspect some login profile is calling ulimit to fix it at 30000 if so just make the necessary change
