Hello again managers,
Since I posted my summary I got new answers which are very interesting
so I am posting a new summary with them.
Many thanks to:

It seems that having C2 security enabled you CAN:

Mandell Degerness helped me a lot with the accounting question:
I asked:
> Does anyone know if it is right that all the pacctn

Yes, it is correct, runacct renames the files to Spacct.date proccesses the
information in them and then cleans the disk deleting them.

I have followed his indication and get now a readable file with the
cpu time consumed by each user.
Thanks a lot for your help
