remain on the backup server. (See “Virtual Hosts and Failover” on
page 212 for more information.)
The Server Severity can be configured on each server. The settings are:
AUTORECOVER. This is the default value for Server Severity. When the
original server is restored, Matrix Server can automatically fail back
virtual hosts to that server, depending on the virtual host’s failback policy.
NOAUTORECOVER. After the server recovers, it is not made available to
host virtual hosts. Instead, Matrix Server disables the server. (You will
need to re-enable the server with the PolyServe Management Console or
mx utility).
The
NOAUTORECOVER setting can be useful when integrating Matrix
Server with custom applications, where additional actions may be
necessary after server recovery and before the server is made available to
host services provided by virtual hosts.
To update a server from the command line, use this command:
mx server update [--serverSeverity=autorecover|
noautorecover] <server> ...
Other Server Configuration Procedures
Delete a Server
When a server is deleted, it is removed from the cluster and from all
Matrix Server applications. Applications hosted by the server may be
adversely affected by the server's removal, and any applications that
exclusively use the server will be destroyed. Before deleting a server, be
sure to take the appropriate actions:
• If the server is primary for a Virtual SQL Server, rehost the Virtual
SQL Server to another node. Also ensure that the server is not a
backup for any Virtual SQL Servers.
• If the server is hosting other Matrix Server applications, disable the
server and wait for the applications to move to other servers.
