errors when creating a stored procedure on DB2 for z/OS

Greetings!

As I make my transition from working on "DB2 for I" to "DB2 for z/OS", I'm finding subtle differences that are tripping me up.

For example, I copied the following simple stored procedure from a website:

CREATE PROCEDURE MYSCHEMA.UPDATE_SALARY_1 (
  IN EMPLOYEE_NUMBER CHAR(10),
  IN RATE NUMERIC(6,2))
LANGUAGE SQL
MODIFIES SQL DATA
  UPDATE MYSCHEMA.EMP
     SET SALARY = SALARY * RATE
   WHERE EMPNO = EMPLOYEE_NUMBER

Select allOpen in new window

But, when creating the procedure, it throws the following error:

WLM ENVIRONMENT NAME MUST BE SPECIFIED

I googled that error, and it was recommended that I add "DISABLE DEBUG MODE":

CREATE PROCEDURE MYSCHEMA.UPDATE_SALARY_1 (
  IN EMPLOYEE_NUMBER CHAR(10),
  IN RATE NUMERIC(6,2))
LANGUAGE SQL
MODIFIES SQL DATA
DISABLE DEBUG MODE
  UPDATE MYSCHEMA.EMP
     SET SALARY = SALARY * RATE
   WHERE EMPNO = EMPLOYEE_NUMBER

Select allOpen in new window

But, it now throws these errors:

REBIND AUTHORIZATION ERROR USING MYSCHEMA AUTHORITY PACKAGE =
LOCDBT1.MYSCHEMA.UPDATE_SALARY_1.(V1) PRIVILEGE = BIND.      

What am I doing wrong?

Thanks for your help!
