The trigger programs are strictly RPGLE with no SQL statements.

Subject: Rép. : Adopted authority and triggers
Trigger should be able to adopt autority. Maybe your trigger programs uses
dynamic SQL, if so, they must be compile with the option DYNUSRPRF(*OWNER). By
dynamic SQL, I mean that the SQL statement to run is not known at compile time.

I am working on a project to give a specific user (LMTUSR) limited access to
our database. As currently designed, LMTUSR is excluded from all but one
library. The external stored procedures (SQLRPGLE and
RPGLE)
in that library adopt the owner's authority to access functions and data in
other libraries. As long as those functions are in modules that only read the
data, they work fine. However, the project requires procedures to insert data
in certain tables that have *BEFORE *INSERT and *BEFORE *UPDATE external
triggers.
From reading the security reference manual (we are on v5r3) I
understand
that triggers do not adopt authority from programs earlier in the call stack.
Changing the external trigger programs to adopt authority (CHGPGM
PGM(EXTTRG) USRPRF(*OWNER)) did not allow LMTUSR to open the files for update
using adopted authority. When the triggers are disabled, UDFs that access the
files complete correctly. When the triggers are enabled, the process fails with
SQL0443 and CPF4236 "Not authorized to open.."
in
the job log. I could not find a parameter on the ADDPFTRG command to adopt
authority.
Did I miss something? While using adopted authority is there a way to insert
and/or update data into files with triggers? If not, I'll probably use a data
queue to get the data to a job whose user does have authority. Or is there a
better way?
Thanks,
Roger Mackie
