Re: [zones-discuss] Difference between resource management attribbutes
There is a kstat. Look at the output of: $ kstat -c project_caps -n 'lockedmem*' -Steve L.

Re: [zones-discuss] Difference between resource management attribbutes
But there is one more thing if i set max-rss i can test it and see the task under specified project does not exceeds the specified rss value but if i set max-locked-memory to 1 gig how can i test that one ? -- This message posted from opensolaris.org ___ zones-discuss mailing list zones-discuss@opensolaris.org
Re: [zones-discuss] Difference between resource management attribbutes
Thank you to both of you .. so i guess its good to use max-locked-memory. -- This message posted from opensolaris.org ___ zones-discuss mailing list zones-discuss@opensolaris.org

RSS means "Resident Set Size" and can be considered to be the amount of RAM that the project's processes are using. Locked memory is the pages of RAM that have been locked - pages that cannot be paged out. > 2. How to restrict the swap memory in projects There is a swap-cap for zones.

This is useful because if the project locks up to it's max-rss, there will be no memory left for it, and it will page non-stop. max-locked-memory can be set lower than max-rss to protect against this. -Steve L. > > 2.

Whats the difference between project.max-locked-memory and max- rss. locked memory is page of memory which can't be swapped by kernel...like share-mem.
