This document explains the meaning of  *** LLA DIFF *** that may appear in the Dataset-Name field when using the WHERE subcommand in the LINKLIST command 


Release : 16.0


The LINKLIST command displays the data sets in the system linklist concatenation.

There are several subcommands that can be used when the information of the LINKLIST command is displayed. One of the subcommands is WHERE which searches all libraries for a specific or generic module name.                                      

When issuing the WHERE command the text *** LLA DIFF *** may appear in the Dataset-Name field.

For example, Issuing the subcommand WHERE MODS0001 the following information may appear:

Why does *** LLA DIFF *** appear on the display?


The HELP command in the LINKLIST display documents *** LLA DIFF ***  as follows:

*** LLA DIFF ***  The WHERE Subcommand and LLA found    
                  different versions of the same module 
                  in the same library. This line shows  
                  the LLA version. The previous line is 
                  the WHERE version. This situation can 
                  occur when a module is copied to a    
                  LINKLIST library but LLA has not yet  
                  been refreshed.                       


This issue is related to Broadcom PDSMAN.


The library has LRDR (Last Reference Date Recording) turned ON and the library is also in LLA and the LINKLIST.             
The LRDR is being updated in the LIBRARY but not the LLA version as "$LLA LRDRUPDT=Y" is not specified in the PDSMAN rules.    
So, there is a DIFFerence between the LINKLIST version and the LLA  version, the Last Reference Date.  


The solution to not seeing the *** LLA DIFF *** is to use "$LLA LRDRUPDT=Y" in the PDSMAN rules.
