Description/symptom of problem:  
PI72065 resolves the following problem:


        ifix for 16003 LOOP IN LIBERTY Z/OS SERVER WHEN ASYNCIO IS ENABLED.                               
                                                                                                          


Directions to apply fix:  
        1. Stop your Liberty profile server(s).                                                           
        2. The following files will be backed up to [LibertyRootDir]/lib/fixes automatically,             
        if they exist (file locations are relative to your Liberty profile install root,                  
        and may not exist depending on the installed product edition or configuration of runtime):        
                                                                                                          
         - lib/native/zos/s390x/bbgzangl                                                                  
         - lib/native/zos/s390x/libzNativeServices.so                                                     
         - lib/native/zos/s390x/bbgzsafm                                                                  
         - lib/native/zos/s390x/bbgzsrv                                                                   
         - lib/native/zos/s390x/bbgzscfm                                                                  
         - lib/native/zos/s390x/bbgzsufm                                                                  
         - lib/native/zos/s390x/bbgzcsl                                                                   
         - lib/native/zos/s390x/bbgzadrm                                                                  
         - lib/native/zos/s390x/bbgzafsm                                                                                                                                
                                                                
                                                                                                          
        3. Open a console and direct it to the location of your iFix jar                                  
        4. Run the command "java -jar 16003-OS390-archive-IFPI72065.jar". The following launch options    
        are available for the jar:                                                                        
                                                                                                          
        --installLocation [LibertyRootDir] by default the jar will look for a "wlp" directory             
        in its current location. If your Liberty profile install                                          
        location is different to "wlp" and/or is not in the same                                          
        directory as the jar then you can use this option to change                                       
        where the jar will patch. [LibertyRootDir] can either be                                          
        relative to the location of the jar or an absolute file path.                                     
                                                                                                          
        --suppressInfo hides all messages other than confirming the                                       
        patch has completed or error messages.        
        
        4.B Change the extended attributes on the installed native modules:
        
 	    extattr +ap lib/native/zos/s390x/bbgzcsl
	    extattr +ap lib/native/zos/s390x/bbgzsafm
	    extattr +ap lib/native/zos/s390x/bbgzscfm   
	    extattr +p lib/native/zos/s390x/bbgzsrv 
	    extattr +p lib/native/zos/s390x/bbgzsufm	    
	    extattr +p lib/native/zos/s390x/libzNativeServices.so    
	    
	    extattr +ap lib/native/zos/s390x/bbgzadrm
	    extattr +ap lib/native/zos/s390x/bbgzafsm
	    extattr +ap lib/native/zos/s390x/bbgzangl                                                              
                                                                                                          
        5. When you next start your Liberty profile server(s), the fix will become active in your runtime.
                                                                                                          


Directions to remove fix:  
        1. Stop your Liberty profile server(s).                                                           
        2. You will need to delete the following files (file locations are                                
        relative to your Liberty profile install root):

         - lib/native/zos/s390x/bbgzscfm                                                                  
         - lib/native/zos/s390x/bbgzsufm

         - lib/native/zos/s390x/bbgzafsm                                                                                                                                
                                                                                                          
        3. You will need to restore the static files by extracting the corresponding backup archive from  
        [LibertyRootDir]/lib/fixes (contents of the backup archive are relative to your                   
        Liberty profile install root).                                                                    
                                                                                                          
        4. When you next start your Liberty profile server(s), use the --clean option.                    
        The fix will then become inactive in your runtime.                                                
                                                                                                          


Directions to re-apply fix:  
        1. Follow the instructions to apply the fix.
