2.2 Installation and Upgrade Information Specific to Alpha
6. Ensure that the Registry server does not restart on the node or nodes you are
upgrading until the upgrade is complete, or, if you are selectively upgrading
nodes, until you determine that you wish to switch over to the new server.
To prevent Registry startup on reboot, you need to check two things on each
node:
a. In the file SYS$MANAGER:SYLOGICALS.COM, comment out any logical
name definitions that contain the string:
"TO_BE_STARTED"
b. Make a note of the original settings for restoring later.
c. If your SYS$MANAGER:SYSTARTUP_VMS.COM automatically starts up
Advanced Server, for example, by issuing the command:
$ @SYS$STARTUP:PWRK$STARTUP.COM
Comment out that line so that Advanced Server does not start on that
node.
7. Proceed with the upgrade on each node.
8. Once all nodes have been upgraded, restart the master server by using the
following command on the node that was originally running the master
server:
$ SET SERVER REGISTRY/START
If you are selectively upgrading nodes, and you are ready to switch to using
Registry services on the upgraded nodes, shut down the Registry server, and
applications using Registry services, on all remaining OpenVMS V7.2-1 nodes
in the cluster using steps 1-6 outlined above. Then you can start the Registry
server on one of the upgraded nodes.
9. Verify that the Registry is operational by using the command:
$ MCR REG$CP LIST KEY HKEY_LOCAL_MACHINE
This command should display at least four subkeys of the HKEY_LOCAL_
MACHINE root key. The same command should be repeated with the HKEY_
USERS root key, which should display at least one subkey.
Note
In the unlikely event that the Registry is not operational, perform the
following: follow the steps in the OpenVMS Connectivity Developer Guide
describing how to restore your database from the snapshot files. If this
fails, delete all the files in the SYS$REGISTRY directory, or rename
the directory, and invoke SYS$STARTUP:REG$CONFIG to reconfigure
the Registry server (see the OpenVMS Connectivity Developer Guide for
details), then import the database file that was saved in step 3.
10. Start the backup Registry servers on the other upgraded nodes using the
command:
$ SET SERVER REGISTRY/START
11. Restore the values of "TO_BE_STARTED" logical name definitions in
SYS$MANAGER:SYLOGICALS.COM and the invocation of Advanced Server
startup in the SYS$MANAGER:SYSTARTUP_VMS.COM file.
