If you don't log out after you change maxdsiz, you'll need to have root do "ulimit -d unlimited". A normal user will have to re-login.
Note: Your maxssiz is fine and you don't want to increase it.

Re: Unlimiting ulimit
Because these are the kernel limiters.

Re: Unlimiting ulimit
#ulimit -d unlimited
User not allowed to change is the error it throws
And the maxssize are required to be modified because it is throwing
ORA-19502: Write error on file: ├в /FS/../../.._FullExp.dmp├в , balockno 547713(blocksize=4096).
ORA-27072: File I/O error.
HP-UX Error: 27: File too large
when a logical back-up is taken.
but the FS is already in large files option.
Thanks

Re: Unlimiting ulimit
>User not allowed to change is the error it throws
Are you root when you do this? (At one time there was a bug where "unlimited" couldn't be used.)
>And the maxssiz are required to be modified because it is throwing
Where do you get this connection?
>The kctune option is not available
You need to mention your OS version. If you don't have kctune(1M), then you have 11.11 and need to use kmtune(1M) and reboot your system.
>But modifying is were i face the problem.
sam should have no problems modifying these kernel parms.
