SNA-DTF SNADTFU_E04032 SNA-DTF Utility V3.2 ECO 4 Summary

 
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 DECnet SNA Data Transfer Facility Server V3.2
on OpenVMS V6.1 through V7.1.  This kit provides fixes for the following
problems:

Problems addressed by the SNADTFU_E04032 Kit:

  o  When GAI received an unbind request, the unbind response
     was never sent out if the user didn't issue a deactivate_
     session call. The LU would stay in the unbinding state.
     The code has been modified so that when an unbind request
     is received the session is terminated properly.

  o  Change fopen in write_log to force opening of a stream_lf
     logfile. The problem was that if a previous version of the
     log file had "var" attributes the new file would inherit
     that attribute and then type out as a single column file.

  o  SNADTF was sending a large file with large RUs to the
     mainframe and receiving IPR's from the other side.
     The buffer allocated to hold the IPR was not being
     deallocated. This was causing a memory leak. The error
     message that would appear was: "-SNADTF-F-UNERETSYS,
     unexpected return code from a system routine %INSVIRMEM,
     insufficient virtual memory" The NEWAI was modified to
     deallocate the IPR buffer.


Problems addressed by the SNADTFU_E03032 Kit:

  o IBM initiated transfers to the VAX failed.

Problems addressed by the SNADTFU_E02032 Kit:

  o  GAI_CLOSE would not deallocate channels on abnormal               
     disconnects. This has now been corrected and the                  
     sna__rcv_callback routine now will deallocate the                 
     channels.                                                         
                                                           
  o  The pacing indicator was never being set on first                 
     request RH in pacing window when sending data to host.            
     This has now been corrected in the SNA__PAC_RQ_SEND               
     routine.                                                          
                                                           
  o  Pacing not working properly when a pacing value was               
     specified. This has been corrected in the sna__tc_                
     dequeue_q_pac by checking if pacing_count is greater              
     than zero. Previously pacing_window was being checked             
     in error.                                                         
 
  o  Fixed the problem where SNARCOPY SHOW JOB command was
     looping, when the generic queue and all other queues are
     empty.

  o  When two or more same copies were running at the same     
     time, the error message "-SNADTF-F-SSFAIL, call to system          
     service $CHANGE_ACL failed" returned. Multiple RCOPY jobs          
     were being submitted that created the same workfile.WRK            
     in the SNADTF$MANAGER directory. RCOPY attempted to set            
     an ACL on the file. However, RCOPY didn't maintain the             
     version number of the work file, so two or more submitters         
     attempted to set the ACL on the same file!                         
              
  o  Fixed an QIO access violation when DTF copy with RMS
     default network block count was above 125.


INSTALLATION NOTES:

The ECO kit is installed with the VMSINSTAL command procedure.

The ECO kit checks to ensure that a valid license is installed before
proceeding.  If one is not found, the installation aborts.  

The minimum supported OpenVMS versions supported by this ECO: 
                OpenVMS VAX V6.1
