Stored Procedure/Powerbuilder - Permission Questions

Environment: Powerbuilder v5.0 running on Windows NT v4.0 Informix - Online v7.21 running on a DG/UX vC2 Question(s): 1. I have some folks here trying to execute a system call that runs a C rou= tine within a stored procedure. they are=20 successful at running the stored proc from dbaccess but get a permissions e= rror when they execute from their Powerbuilder app. the SQL code -668 with= ISAM code -172. does anybody have any ideas what the cause might be? 2. this is sort of related to the first question, at least I think it is. w= e have a standard set of debug code in all our stored procs that basicallly= allows you to generate a trace file (SET DEBUG FILE TO ...) by passing a p= arameter to the stored proc. we have designated /tmp on our UNIX server as = the directory where we would like all these trace files to be written. howe= ver, we get SQL code -648 with ISAM -13. this setup works fine if we execu= te the stored proc from dbaccess but not from Powerbuilder. again, does any= body have any experience with this one? I am not sure if these problems we are experiencing are Powerbuilder, INFOR= MIX or our UNIX system, but I thought someone out there might have experien= ced my pain on this one. thanks in advance! alicia =20 =09 ******************************************************************** Alicia Slaughter =09 EDS-D/SIDDOMS 5113 Leesburg Pike, Skyline 4 Suite 800 Falls Church, VA 22041-3201 phone: 703-845-3513 fax: 703-845-3899 =20 email: alicia.slaughter@med.osd.mil *********************************************************************
