OpenVMS ALPLIBR02_061 Alpha V6.1 LIBRTL ECO 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 the LIBRTL routines on OpenVMS Alpha V6.1 - V6.1-1H2. 

Problems addressed in the ALPLIBR02_061 kit:

  o  Because multi-version kits are no longer being issued, the 
     ALPLIBR05_070 kit, which was for OpenVMS Alpha V6.1 through 
     V7.0, has been broken down so that there is a kit for each 
     version.  This kit, ALPLIBR02_061, is the V6.1 portion of
     ALPLIBR05_070.  There are no new fixes in this kit.


Problems addressed in the ALPLIBR05_070 kit:

  o  The OpenVMS operating system has a documented delta-time
     restriction that may cause an error in some applications and
     OpenVMS components beginning on or around 19-MAY-1997.  This ECO
     corrects this potential problem by removing the delta-time limit. 

     Applications and OpenVMS components most likely to experience
     errors are those that pass delta-time arguments with values
     exceeding 9999 days on system-supplied date routines.  The most
     likely date that these errors will occur is 19-MAY-1997:00:00,
     which is 10,000 days after the common UNIX time origin of
     1-JAN-1970. 

     This problem is fixed in OpenVMS Alpha V7.1.


Problems addressed in the ALPLIBR04_070 kit:

  o  Heaps that are removed from the heap pending list are only
     merged with the most recently returned heap.  This can lead to
     heap fragmentation.


Problems addressed in the ALPLIBR03_070 kit:                 

  o  LIBRTL.EXE was not replaced in IMAGELIB.OLB.


Problems addressed in the ALPLIBR02_070 kit:

  o  The 10,000 day limit in LIB$CVT_TO_INTERNAL_TIME causes problems 
     for DECthreads since it is using this routine to convert UNIX
     times to VAX time.  It will fail to work on 19-May-1997.

  o  LIB$STAT_TIMER produces incorrect results.  Elapsed time jumps
     significantly from the initial value to the next returned value.

  o  Problem noticed using OTS$DIV_PK_LONG or OTS$DIV_PK_SHORT LIBRTL  
     routine.  Packed value 11259 divided by 1, yielded 1125.90083841.  
     Only a handful of numbers cause bad results.


Problems addressed in the ALPLIBR01_070 kit:

  o  The multiplication algorithm for delta time was faulty.  This
     is a regression in V7.0.


Problems addressed in the ALPLIBR03_062 kit:

  o  When setting host into a DECnet PhaseV system, the logical name
     SYS$REM_NODE is incorrectly set.  When the code was originally
     written, there was no support for node synonyms.  The code
     does not get the right values from the system call.


INSTALLATION NOTES:

In order for the corrections in this kit to take effect, the system
must be rebooted.  If the system is a member of a VMScluster, the 
entire cluster should be rebooted.
