HP Services Software Patches - vaxlat02_061
 
NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
       The name of the compressed file will be kit_name-dcx_vaxexe
       for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
 
       Once the file is copied to your system, it can be expanded
       by typing RUN compressed_file.  The resultant file will
       be the OpenVMS saveset or PCSI installation file which
       can be used to install the ECO.

ECO KIT SUMMARY:

An ECO kit exists for LAT on OpenVMS VAX V6.1.  This kit addresses the        
following problems: 


PROBLEMS ADDRESSED IN VAXLAT02_061 KIT

  o  VCRP packets are being overwritten.

  o  A CREATE LINE LINK$NAME/DEV=XXA0:  command in LATCP  can  crash
     the system.

  o  After executing the following commands:

       LATCP> CREATE SERVICE SERVICE1/APPL               
       LATCP> CREATE SERVICE SERVICE2/APPL               
       LATCP> CREATE SERVICE SERVICE3/APPL               
       LATCP> DELETE SERVICE SERVICE2                    
       LATCP> SET SERVICE SERVICE3/STATIC_RATING=1       

     the static ratings for services following SERVICE2 can  not  be
     changed.

  
PROBLEMS ADDRESSED IN VAXLAT01_061:

  o  System crash due to memory being  allocated  twice  during  TSM          
     TEST LAT command.                                                        
                                                                              
  o  System crash due to dedicated port queue corruption                      
                                                                              
  o  The LATACP process loops, blocking further LAT connections               
                                                                              
  o  SET HOST/LAT connections hang when connected to OSF systems.             
                                                                              
  o  System crash during link deletion and/or creation.                       
                            
  o  CPUSPINWAIT BUGCHECKs                                                    
                                                                              
  o  Connecting to a dedicated port for application service  results          
     in  a protocol violation and the "invalid credit" counter being          
     incremented.                                                             
                                                                              
  o  Fix possible CPUSPINWAIT crashes in PORT_CANCEL.                         
                                                                              
  o  The LAT architecture describes the response timer field in  two          
     places.   Once, it is described as a value during solicitation.          
     Secondarily, it  also  describes  how  to  use  that  value  to          
     generate  a  random  number  timeout  period  within acceptable 
     limits.  In one place, "10ms units" are referred to and in  the          
     other,  "seconds"  is  referred  to as the unit of time.  LTDEF          
     thought the "10ms units"  was  the  correct  value  for  a  LAT          
     message when "seconds" is needed.                                        
                                                                              
                                                                              
  o  In a SET HOST /LAT session,  during  certain  circumstances  of          
     lost  messages,  LTDRIVER is erroneously setting the RRF bit in          
     the master message without checking to see if  the  circuit  is          
     doing  delayed acknowledgments.  RRF should not be set unless a          
     circuit has successfully negotiated delayed ACKS                         
                                                                              
  o  LATACP crashes with PGFIPLHI                                             
                                                                              
  o  LTDRIVER crashes with INVEXCEPTN                                         
                                                                              
  o  Some applications use break, through  the  system  service,  to          
     write to their numerous terminals at the same time.  When LATCP          
     is running, the management LTA device created by LATCP is  also          
     broadcast  to.   This  slows  done the application to the point          
     where the application exhausts its byte limit                            
                                                                              
  o  An MC LATCP CREATE PORT command with  an  invalid  device  name          
     will crash the system.
