Hello all,

does anyone had a problem executing topas as a regular user?

Don't know if this helps, but I remember topas as being meant to be used
as root only, but just checked a 5.2 system and a normal user can
execute it just fine - r-xr-xr-x.

Did I miss some change or just find another failure in my wetware?

All,

As far as I know the /dev/kmem is being read by topas and there might
be the 'rights' issue !

.... correct

Yes- since /dev/kmem has permissions of:
cr--r----- 1 root system 2, 1 Apr 25 2005 /dev/kmem
a regular user can access it to run topas only if he is a member of the
group "system"

Not true, at least as of the latest maintenance levels any user can run
topas.

Thanks for that advice...is there like a refresh command you can use if
topas fails to execute right away?

however, you have to run it once as root before any regular users try to
use it. otherwise, users will get errors saying topas can't access
/etc/Spmi_shm_hook . the first time you run topas as root, it will create
that file.

Yes , anyone can run the topas , provided /dev/kmem file has read
permission . But remember , this will

lead to wrong results. If you run it with a non-system user, the
displayed values will be wrong.

For eg, you can see that the I/O to the hard disks will be always zero
..I am not sure the same is the case with other setup

but as far as our server are concerned it is like that. We use AIX 5.2
, P690 and EMC SAN
