HP Services Software Patches - alpcmar04_062

 
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.

     Installation Rating:  3 - To be installed on all systems running
                               the listed versions of OpenVMS which
                               are experiencing the problems described.


ECO KIT SUMMARY:

An ECO kit exists for CMA$OPEN_RTL and CMA$RTL on OpenVMS Alpha V6.2
through V6.2-1H3.  This kit addresses the following problems: 

Problems Addressed in the ALPCMAR04_062 Kit:

  o  Paths to initiate the time slicer for the pthread api and the
     exception returning api failed to enable the time slicer. 


Problems Addressed in the ALPCMAR03_062 Kit:

  o  Prior to this change, the DECthreads time-slicer would be
     operational regardless of whether any threads had actually
     been created.  This change delays enabling the time-slicer
     until the first thread create operation.


Problems Addressed in the ALPCMAR02_062 Kit:

  o  A non-Fatal exception that is raised is not caught in V6.2.
     This non-fatal exception was caught in V6.1.


Problems Addressed in the ALPCMAR01_062 Kit:

  o  When many threads are created and detached, it can be
     observed that calls to LIB$FREE_VM_PAGE are made during
     CMA$THREAD_CREATE that will sometimes mark pages as freed that
     were not owned/allocated by DECthreads.


INSTALLATION NOTES:

The system does not need to be rebooted after this kit is installed.
However, if you have other nodes in your OpenVMS VMScluster, they should
be rebooted or you should install this kit on each system in order to
make use of the new image(s). 


REMOVAL INSTRUCTIONS:

Remove this kit and restore the original files and libraries by logging
into the SYSTEM account, and typing the following at the DCL prompt: 

     @SYS$UPDATE:CMA$ECO_DROP
