Issue/Introduction

When applying PTF LU13427, there is a HOLD action that affects "sites with an installed written DCCTFPR prefix exit."

The Hold steps indicate that module DCCTFAA containing the prefix exit must be reassembled if it is used.

Where would the DCCTFAA or DCCTFPR modules be? 

Environment

z/OS

Datacom CICS Services

Resolution

Because of the HOLD action, you need to know if you are using the Broadcom-supplied DCCTFPR module, or if you have modified it to contain the prefix exit for your site.

Here is how you can find the module and load lib for this:

1. In the CICS region, issue the command CEMT I PROG(DCCTFPR) <enter>, and then use the "S" line command against the results to give the details of the module. If you scroll down a couple pages in the details, you will see from where the module was loaded:
   Library(DFHRPL)
   Librarydsn(....your loadlib) 
   If you are using the original module, it should be coming from the *.CAB1LOAD used for Datacom CICS Services. If there is another loadlib showing--like a CUSLIB or something else, then you have likely added your logic through DCCTFAA.
2. You can run an AMBLIST against this load module:

   //   EXPORT SYMLIST=(*)
   //   SET LLIB=Your.loadlib from #1, above.
   //   SET LM01=DCCTFPR                      
   //*                                        
   //ST1      EXEC PGM=AMBLIST                
   //SYSPRINT DD  SYSOUT=*                    
   //SYSLIB   DD  DISP=SHR,DSN=&LLIB          
   //SYSIN    DD  *,SYMBOLS=JCLONLY           
    LISTLOAD MEMBER=&LM01,OUTPUT=BOTH         
   /*                                       

   The output here will show a module map of the contents, and you would see entries for the CSECT DCCTFAA if it was used. Our shipped DCCTFPR module does not have DCCTFAA in it.
