script to run onmode (and not as user informix)

hi, i think i saw something like that a couple of weeks ago, but then i lost my email messages. i have an assigned user(not user informix) who runs jobs to load data into an informix database vers.7.12UC4 on solaris 2.5.1. and being it's a shared environment, sometimes the tables that are to be dropped are held, and the load job failed. previously i setup a remsh script, but my sa took that away, as it is a security risk. i tried the setuid but that did not work also. i would appreciate any suggestion or sample script that does not use remsh, and not using the informix user a/c to run onmode -z. thanks, hk
