DSNA314I UNABLE TO LOAD CICS STUB ROUTINE DFHXCSTB. SYSTEM REASON CODE=X'hhhh' SYSTEM COMPLETION CODE=X'hhhh'

Explanation
 DSNACICS was unable to load the CICS® stub routine DFHXCSTB.

System action
 The stored procedure DSNACICS does not call the CICS transaction.  DSNACICS processes
the next request.

System programmer response
 Ensure that the STEPLIB statement
in the startup procedure for the stored procedure address space specifies
the CICS library that contains
DFHXCSTB. DFHXCSTB is in the CICS EXCI
library (SDFHEXCI).  This library must be APF authorized.
 Add
a DSNDUMP DD statement to the JCL startup procedure for the stored
procedure address space in which DSNACICS runs. Then rerun the application
that calls DSNACICS. This causes Db2 to
generate an SVC dump whenever it issues an error message for DSNACICS.
 If you suspect an error in Db2, you might need to report the problem. For information about identifying and reporting the
problem, see Collecting diagnostic data. Collect the following diagnostic items:
Console output from the system on which the job was run, and a listing of the
SYSLOG data set for the period of time that spans the failure. 

Dynamic dump, taken to SYS1.DUMPxx data set, by Db2 (04E
and 04F abends).

CICS trace listing.
