Problem - Migration from OAS 4 to 9ias

Question

We have upgraded the application server from 4 to 9ias and are
now running into problems with calling stored PLSQL procedures.
Here is a code snippet of an example stored proc:
PROCEDURE Test (
num_entries in NUMBER,
name_array in OWA.vc_arr,
value_array in OWA.vc_arr,
reserved in OWA.vc_arr
Basically if I call this procedure (w/o any paramaters) using
the old application server and associated plsql cartridge, it
runs no problem loading the webpage and such. Now when I try to
call the same procedure using the new 9ias mod_plsql, it says
there is an error.
Error output (when connecting using browser)
Test: SIGNATURE (parameter names) MISMATCH
VARIABLES IN FORM NOT IN PROCEDURE:
NON-DEFAULT VARIABLES IN PROCEDURE NOT IN FORM:
NUM_ENTRIES,NAME_ARRAY,VALUE_ARRAY,RESERVED
We have found that if you do not set a default values for any of
the parameters that it comes up with this error. Is this in fact
the case? Do default values have to exist for procedure
variables when using 9ias? If so how would I set the default
values for this test procedure if Number is integer, and the
rest are arrays.
Does anyone know of a migration tool specifially for this
purpose as we are going to update multiple procedures?
Any help would be beneficial.

Answer 1

Gurus,
I figured it out. I should read the documentation more closely.
Found it in...
For questions about backwards compatibility with OAS, refer
to "Using Flexible Parameters and the Exclamation Mark".
I just have to put a exclamation mark in front of the procedure.
Easy fix
