You do need the system to be able to modify the database - for any user. So, IDS runs a SUID root, SGID informix program called oninit, and uses the temporary, raised privileges to open and modify the underlying chunks. -- Jonathan Leffler #include <disclaimer.h> Email: jleffler@earthlink.net, jleffler@us.ibm.com Guardian of DBD::Informix v2005.02 -- http://dbi.perl.org/

Hi, I believe you question has to be more specific, Jonathan did just point out that the permissions are set correctly for the rootdbs chunk. So, what is your problem really (since everything is working correctly as I understand ...)
