Viewing Version Information
Knowing the exact version of your
Failover Server Service
is an advantage if you need to contact product support.
1. Right-click
the
notification area's
Failover Server Service
icon.
2. From the menu that appears, select
About...
3. A small dialog opens. The dialog will show the exact version of your
Failover Server Service.
During installation of the failover server, you specified a user account under which the
Failover Server Service
should
run. For the failover server to work, it is important that the user account in question has access to your OnSSI RC-E
system with administrator rights.
To verify whether the user account has access to your OnSSI RC-E system, do the following:
1. In the Management Client's Site Navigation pane (see "Panes Overview" on page 36), expand
Security
and
select
Roles
.
2. In the Overview pane (see "Panes Overview" on page 36)'s roles list, select the
Administrators
role.
3. In the Properties pane (see "Panes Overview" on page 36)’s role settings list, verify that the required user is
listed.
If the user is not listed, add the required user to the
Administrators
role by clicking the
Add...
button below the
role settings list. For more information, see Assign Users & Groups to/from Roles (see "Assign and Remove
Users and Groups to/from Roles" on page 149).
Manage Failover Servers
A failover server is a spare recording server which can take over if a regular recording server becomes unavailable. It
should therefore always be installed on a separate computer. A failover server has two services:
A Failover Server Service, which handles the processes of taking over from the regular recording server. By
default, this service is always running since it constantly checks the state of relevant recording servers.
A Recording Server Service, which enables the failover server to act as a recording server while the regular
recording server is unavailable. This service is only started when required, i.e. when the failover server should
take over from the regular recording server. Starting this service typically takes a couple of seconds, but may take
longer depending on local security settings, etc.
A failover server
must
be able to communicate with all cameras of the recording server(s) from which it should be
able to take over.
Involved Servers:
1. Recording
server
2. Failover
server
3. Management
server
Failover Steps:
1. To check whether it is running or not, failover server has a non-stop TCP connection to a recording server.
2. This connection is interrupted, i.e. the recording server is not running.
