QADBXREF authority - aliases creation

[Krzysiek]

Hi all,

I have an issue with QSYS\QADBXREF file - it keeps aliases on tables.
I take care of an application that works on many places (servers) and
on one of them it's not possible to create alias. I've checked the
authority of QADBXREF file on this 'problematic' machine and it's as
follows:

Object ----------Data--------- --------Object---------
User Group Authority Read Add Upd. Del. Exec. Opr Mgt Exist Alter Ref
*PUBLIC USER DEF X
On all the other machines (there is no problem to create aliases and
then to use them) it's:

Object ----------Data--------- --------Object---------
User Group Authority Read Add Upd. Del. Exec. Opr Mgt Exist Alter Ref
*PUBLIC *CHANGE X X X X X X

My questions are:
1. How to enable aliases creation?
2. Are there any SQL setting on AS400 that enable/disable aliases?

On IBM sites I found a note that QADBXREF file is one of the files
that are always opened so there is no possibility to change the
authorities...

Thanks in advance for any suggestions,
