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 OPCOM, REPLY and REQUEST on OpenVMS VAX V6.2.

Problems addressed in VAXOPCO02_062:

  o  The previous kit did not contain all documented fixes.

Problems addressed in VAXOPCO01_062:

  o  On OPCOM restart, the log file was not restarted.

  o  REQUEST did not accept a string with a length greater than 128
     characters.

  o  OPCOM crashed with a SSRVEXCEPTN error.

  o  Raising exceptions, while in kernel mode only, leads to a
     system crash (SSRVEXCEPT error) in the CLUSCOMM_COD_ALLOCATE
     module.


Problems addressed in VAXOPCO01_070 for OpenVMS VAX V6.2:

  o  In certain circumstances, FAILING_OPCOM and OPCOM run on                 
     the system at the same time.  They both go into a $HIBER                 
     state waiting for incoming messages.                                     


INSTALLATION NOTES:

The system/cluster does not need to be rebooted after this kit is 
installed.  However, the OPCOM process should be shutdown and 
restarted in order for all kit changes to take effect.     

The OPCOM process should be stopped using the STOP OPCOM command.
If this command fails, then STOP/ID= (pid is process ID) can
be used instead.

Next, the logical OPC$OPCOM_STARTED should be deassigned, which is
done by using the command:

  DEASSIGN/SYSTEM/USER OPC$OPCOM_STARTED

Once OPCOM is stopped (no OPCOM process is active), the following
command will restart OPCOM:

  @SYS$SYSTEM:STARTUP OPCOM
