Additional Information and Tips › Independent BlackBerry SQL Instance

Independent BlackBerry SQL Instance

Arcserve RHA supports the independent transfer of a single instance (on a multi-instance or multi-function SQL server) to a Replica server. This section is directed to administrators using a shared SQL server to host the BES configuration data, and wish to protect only the BES portion via Arcserve RHA. Performing these steps ensures that only the independent instance is switched over while other instances remain working on the Master server.

Implement the Solution

1. Confirm that the SQL servers and additional instances comply with all the specifications described in The BlackBerry HA Solution.
2. Set up an additional DNS Host (A) Record for the Master SQL server. This DNS record is used for all BES HA purposes related to the SQL database. It should have a unique name and must be a host (A) record type; CNAME alias records are not supported.
3. Ensure you use the additional record just created in BlackBerry Server Setup, not the hostname for all SQL configuration settings in BES and ODBC.
4. When you configure the scenario, make sure you select only the desired instance that contains the BES Configuration database.
5. From the Switchover dialog, enter the additional DNS Record as the Master Fully Qualified Name. This is the record that is redirected during switchover.
