Modification Date:  16-JUN-1999
Modification Type:  New Kit

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 IPC Services and SCS on OpenVMS VAX V6.2.  
This kit addresses the following problems: 

  o  The VAXDDTM01_062 remedial kit included SYS$IPC_SERVICES.EXE
     to fix an SCS problem.  Since this problem is IPC specific,
     it is being removed from the DDTM kit and moved to this
     IPC-specific remedial kit.

     This remedial kit has no new problem corrections.  It is
     simply a re-packaging.   If you have installed the
     VAXDDTM01_062 kit, then this kit does not need to  be
     installed.

  o  After a transient SCS failure and as the two communicating
     machines attempt to recover from it, one (or often both) of
     those machines crashes with an access violation.  The crash
     may occur, depending on the exact timing of the failure with
     respect to the messaging activity at the time, at a number  of
     accesses to the structures that SCA maintains.


INSTALLATION NOTES:

The images in this kit will not take effect until the system is
rebooted.  If there are other nodes in the VMScluster, they must 
also be rebooted in order to make use of the new image(s).  

If it is not possible or convenient to reboot the entire cluster at 
this time, a rolling re-boot may be performed.
