DSNH20228I A STACKED DIAGNOSTICS AREA IS NOT AVAILABLE

Explanation
 A stacked diagnostics area is only accessible
from within a handler in a native SQL routine. 
This error can
occur when the STACKED keyword is specified in a GET DIAGNOSTICS statement
outside of an SQL procedure.

System action
 The statement was processed.

Programmer response
Modify the application logic so that the
STACKED diagnostic is only accessed from within a handler. If the
routine is an external SQL procedure, or a host language program then
the STACKED keyword cannot be used.
