OpenVMS ALPSYSB03_062 Alpha V6.2 SYSTEM ECO Summary

TITLE: OpenVMS ALPSYSB03_062 Alpha V6.2 SYSTEM 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 SYSTEM Components on OpenVMS Alpha V6.2
through V6.2-1H3. This kit addresses the following problems: 

Problems Addressed in ALPSYSB03_062:

  o  Three problems are related to the IEEE handler on OpenVMS:

     1.  Adding two floating point values, which  should  result  in    
         0.0 in some cases (if one of the two operands is negative),    
         gives a -0.0 result instead of 0.0.                            
                                                                    
     2.  Adding/subtracting a zero to a denormal value  yields  zero    
         instead of the denormal value.                                 
                                                                    
     3.  A  negative  double  float  converted  to  a  float  yields    
         +infinity instead of -infinity.                                


Problems Addressed in ALPSYSB02_062:

  o  Installation of the ALPSYSB01_062 remedial kit on systems  with
     a  SYSTEM_SYNCHRONIZATION_PRF.EXE  image  could  result  in the    
     installation failing because  of  regression  issues  with  the    
     image   on   the  system  vs.   the  image  in  the  kit.   The    
     SYSTEM_SYNCHRONIZATION_PRF.EXE image has not shipped as part of    
     VMS and should not appear as part of the consolidated SYS kits.    
     This image as well as other images  that  have  not  previously    
     shipped  in  remedial  kits  have been removed from the ALPSYSB    
     remedial kit.                                                      
                                                                    
     There are no new problem corrections in this kit.  If you  have    
     successfully  installed  the ALPSYSB01_062 remedial kit, you do    
     not need to install the ALPSYSB02_062 kit.                         


Problems Addressed in ALPSYSB01_062:

  o  The AUDIT server runs into an access violation in  kernel  mode
     when it encounters an unknown security class.


Problems Addressed in ALPSYS15_062:

  o  A SSRVEXCEPT crash occurred early in the boot  process  when  a
     new  'fixed'  image  was  used.  The Signal Array had an ACCVIO
     with   the   message   code   in    the    offending    PC    =
     EXE$WRTMAILBOX+00C1C and in the operand = EXE$DELMBX+006E4.


Problems Addressed in ALPSYS13_062:

  o  On OpenVMS V6.2, operations involving quiet  NaN  values  cause
     the  IEEE status register to get set inappropriately.  A second
     problem was that converting a NaN float or double  value  to  a
     long integer causes an integer overflow exception.

 
Problems Addressed in ALPSYS08_062:

  o  A DOUBLDEALO BUGCHECK during process rundown, caused by  double
     deallocation of a memory block.

     There is a small window of opportunity between the time the ORB
     is  deallocate  and  the time its address is cleared in the UNC
     that the image could be interrupted and a rundown thread  could
     pick up the ORB address and try to deallocate it again.


Problems Addressed in ALPSYS04_062:

  o  The system hangs with a process  in  RWPAG  while  auditing  an
     event.


Problems Addressed in ALPSYS02_062:

  o  SYS$ENQ System Service call/program hangs due to the event flag
         not being set.

  o  Due to an image build problem, the LOCKING.EXE  image  included
     in  the  ALPSYS01_062  kit  did  not contain the problem fix it
     should have.


Problems Addressed in ALPSYS01_062:

  o  Under certain conditions, a fork lock used by the  virtual  I/O
     cache may be created with an incorrect length.  This results in
     unsynchronized data access which can cause corruption.


INSTALLATION NOTES:

The images in this kit will not take effect  until  the  system  is
rebooted.

If you have other nodes in your VMS  cluster,  they  must  also  be
rebooted  in  order  to make use of the new images.  If it is not
possible or convenient to reboot the entire cluster at this time, a
rolling re-boot may be performed.
