what are MPCTL and SPUCTL privilegies ?

[Jdamian]

Hi

I typed a bad option of setprivgrp command. The following short help is printed:

setprivgrp:no privilege associated with peter
usage: setprivgrp -n|-g|group-name [RTPRIO] [MLOCK] [CHOWN] [LOCKRDONLY] [SETRUGID] [MPCTL] [RTSCHED] [SERIALIZE] [SPUCTL]
or setprivgrp -f file-name

MPCTL and SPUCTL aren't discussed in manual pages. What do they mean ?

The 11.23 man pages say:

SPUCTL
Allows certain administrative operations in the Instant Capacity On Demand (iCOD) product. See
that product's documentation for more information.

MPCTL
Can use mpctl() to change processor binding, locality domain binding or launch policy of a process (see mpctl(2)).

Best regards...
Dietmar.

Thanx everyone.

HP-UX in my box is 11.00, not 11i

Why all those changes aren't reflected in HP-UX 11.00 manual pages ?

I have searched out about your last question. I don't know why MPCTL and SPUCTL are only documented for 11.i and up on docs.hp.com.
About setprivgrp for 11.00 on docs.hp.com I see Sep 2000; maybe older releases of HP-UX 11.00 had not those reference. Your 11.00 system is newer of Sep 2000, it is newer than that documentation but it just a thought...

Best regards,
Ettore

MPCTL used to be an undocumented, unsupported feature in versions prior to HP-UX 11i.
It has been around for such a long time and it was a useful interface, HP finally decided to officially support it.

I believe that SPUCTL is still in the boat of being undocumented and unsupported.
