RELEASE NOTES for HP Performance Agent (OVPA) for OpenVMS Version 4.0
        ======================================================================

Restrictions
------------
This version of HP Performance Agent (OVPA) for OpenVMS has been tested
with the HP OpenView Performance Manager (OVPM) Version 5.00 and later.
But HP does not recommend using OVPM Version 4 with this version of 
OVPA, even though it works.

The following display fields in OVPM are not supported on OpenVMS:
        - The Disk ID display shows up blank. Disk ID is a unique ID on UNIX 
          and it is not supported on OpenVMS. However, device name is a unique 
          ID on OpenVMS and can be used instead of Disk ID.
        - INODE is not applicable to OpenVMS.  HP is investigating an
          alternative metric for INODE.


Documentation Notes
-------------------
- If you have installed TDC clusterwide, the OVPA installation does not
  recognize this TDC installation. TDC must be installed on EACH OpenVMS node 
  that you want to install OVPA on.

- Many of the documents delivered with this version of OVPA for OpenVMS are
  written for Linux; however, the same documents hold good for OpenVMS.

-  Shut down OVPA by executing the @SYS$STARTUP:OVPA$SHUTDOWN command prior 
   to installing an update to the TDC software from the TDC web site. 

   Failure to do so prevents the newly-installed TDC software from 
   running correctly.

   If you do not perform the above, the TDC installation installs an 
   updated version of the TDC execlet image into SYS$LOADABLE_IMAGES, 
   and the newly-installed TDC software attempts to load the updated 
   execlet when it starts a collection. That attempt is blocked because 
   the previous version of the execlet image is still in use.

   However, the TDC collection operation continues but will not be able to 
   gather most process- and disk-I/O metrics.
