DB2 FOR LUW / DB2FORLUW / 970 - DB2

If your PL/SQL application opens a cursor using dynamic SQL 
text, the cursor will be closed after a COMMIT operation.  This 
is incorrect for PL/SQL code, where cursors should remain open 
after a commit.  In other words, they should exhibit the same 
behaviour as an equivalent SQL PL cursor declared with the WITH 
HOLD attribute. 
 
The following test script demonstrates the behaviour.  The 
CLOSE statement should complete successfully; instead, it fails 
with error SQL0501N: 
 
SQL0501N  The cursor specified in a FETCH statement or CLOSE 
statement is not open or a cursor variable in a cursor scalar 
function reference is not open.

If a dynamic cursor is required and it is necessary to keep the 
cursor open through a commit operation, consider writing a 
helper routine in SQL PL (instead of PL/SQL) to dynamically 
open a cursor variable WITH HOLD.
