DTF SNADTFS_E04032 SNA Data Transfer Facility Server 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 VAX V6.1 through V7.1 and OpenVMS Alpha V6.1 through V7.1.

NOTE:  The DECnet SNA Data Transfer Facility Server Release Notes contain a 
       complete explanation of this release. Below is a brief description of 
       the problems fixed by this release.

PROBLEMS ADDRESSED IN SNADTFS_E04032:

  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 IN SNADTFS_E03032:

  o IBM-initiated transfers to the VAX failed



PROBLEMS ADDRESSED IN SNADTFS_E02032:

  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
