Installing the Command Center Server in High Availability Mode

Dec 18, 2015

You can configure two Command Center servers to work as a high availability (HA) pair by configuring a server as primary and the other server as secondary. HA pair mode of operation allows you to ensure uninterrupted management of network devices by allowing the secondary Command Center server to take over in case the primary server fails, terminates, or shuts down.

Note: Both the primary and secondary servers should be in same time zone or with the same time settings. This is to ensure an accurate timeline for performance data in case of a failover.

To set up Command Center to work in high availability mode

  1. Install Command Center on the server that you want to use as the primary HA server as described in Installing the Command Center Server on Windows or Installing the Command Center Server on Linux and connect to your database.
  2. Start the Command Center server.
  3. Install Command Center on the server that you want to use as the secondary HA server connecting to the same database to which the primary HA server is connected.
  4. Start the Command Center server.
    Important: Citrix recommends you to start the server which you intend to assign as primary server, connect to the Command Center client to ensure that the server is started, and then start the other server, which is automatically assigned as a secondary server.
    Note: For a successful HA failover, ensure that both the primary server and the secondary server are DNS-enabled.
