PGP Universal Server - High Availability Mode

If you have multiple PGP Universal Servers clustered together, you can choose
to store PGP Universal Web Messenger user account information in either of 2
modes.

* Home Server Mode assigns a home PGP Server for each new PGP
Universal Web Messenger user account. All account information for an
external user exists on a single cluster member.

* High Availability Mode replicates new PGP Universal Web Messenger user
accounts on all clustered PGP Universal Servers. All external user account
information exists on all members of the cluster. If a cluster member is not
functioning, PGP Universal Web Messenger users will still be able to use
the service.

Switching account creation modes does not modify existing accounts. Any user
account created in High Availability Mode will continue on in that mode, even if
High Availability Mode is later turned off. Only users created after you turn the
mode off will be affected. If your PGP Universal Server is in Home Server
Mode, and you later turn on High Availability Mode, only new user accounts will
be replicated across the cluster, and all existing user accounts will remain saved
to a single server.

If you have migrated to PGP Universal Server 2.5 or later and choose to enable
High Availability Mode, only PGP Universal Web Messengers users created
after your migration will be affected. Existing PGP Web Messenger users will
not be converted. If you need to convert existing user accounts, contact PGP
Support (www.pgp.com/support) for help.

PGP Universal Web Messenger messages are replicated to all members of the
cluster, even those not running the service.

Click the Switch Mode button to turn High Availability Mode on or off.
