× The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

In ACS are you using SQL or System Naming Conventions.
STRSQL and Green Screen uses per default System Naming conventions, so the
library list is searched for all (database) objects accessed with SQL.

When using SQL Naming conventions the Library List is not searched.
Unqualified specified tables and views are searched in the default schema
(can be set with SET CURRENT SCHEMA - but is not the same as the *CURLIB).
Unqualified specified Stored Procedures, User Defined Functions, User
Defined Table Functions are searched in the SQL path, which can be set with
SET CURRENT PATH. In the CURRENT PATH multiple schemas separated by a comma
can be specified and even the special value *LIBL is allowed.

In either way, make sure you use the same naming conventions when generating
and running the routines.

Mit freundlichen Grüßen / Best regards

Subject: SQL wrapper around service program

Hi All

I've been reading on this list for quite a while and it has brought me a lot
of knowledge for which I would like to thank you all!

Having said that I ran up to a problem for which I really don't see what to
research next and where the cause of the problem even lies.

I have a service program written in SQLRPGLE with at this moment 2
subprocedures. I'd like to call one of them via a stored procedure wrapper
so I can use that in my SQL. I did that before with another RPGLE service
program and it worked fine at the first attempt. The service program is in
PWSLIB, as is the stored procedure.

The stored procedure:
create or replace procedure DVLTMF_SetHash
-- Stelt de hashcode in DVLTMF in.

(in WSLIB_pmx char(10))
program type sub
language rpgle
not deterministic
specific DVLTMS04
not fenced
no sql

parameter style general

The service program exists, the subprocedure is there. I can call the
subprocedure from RPG. I can *also* call the stored procedure from STRSQL in
a 5250 session which really strikes me.

call dvltmf_sethash('DRGPWS81');

With the same library list in ACS I get this error

SQL-status: 42724 Leverancierscode: -444 Bericht: [SQL0444] External program
*N in *N not found. Oorzaak . . . . : An attempt was made to CALL
procedure or invoke function DVLTMF_SETHASH in PWSLIB. External program or
service program *N in schema *N was not found. Recovery . . . : The
external program or service program associated with the procedure or
function cannot be found. Ensure that an object exists with the name
PROCEDURE, or ALTER FUNCTION statement. If no name was specified, ensure
that an object with a name which matches the procedure or function name
specified exists. If a program name was specified, a program object must
exist. If an entry point name was specified, then a service program object
must exist. Try the request again.

I can call the stored procedure unqualified because PWSLIB is in the *libl
and I use *SYS naming both in 5250 and ACS.

So I presume that there is something wrong in ACS, but just can't point my
finger to what that would be.

Does anyone have a suggestion?

Kind regards,
