Setting the Default Search URL in a GSA Mirroring
Configuration
In a mirroring configuration, the default search URL is specified using a relative URL. Whether you are
setting up GSA mirroring for the first time or updating the default search URL in an existing mirroring
configuration, change the default search URL on the master and the replica search appliances. The
default search URL on the master search appliance is not replicated to the replica search appliances.
For example, assume that you have one search appliance, gsa1, that you use for search. The default
search URL for gsa1 is http://gsa1/
search?site=default_collection&client=default_frontend&proxystylesheet=default_front
end&proxycustom=%3CHOME/%3E.
If you add a second search appliance, gsa2, and configure mirroring, you must change the default
search URL on the master search appliance to /
search?site=default_collection&client=default_frontend&proxystylesheet=default_front
end&proxycustom=%3CHOME/%3E.
To change the default search URL:
1. On the master search appliance, log in to the Admin Console.
2. Click Administration > System Settings.
3. Type the new default search URL in the Default Search URL field.
4. Click Update System Settings.
Alternatively, you can also set up a single round-robin DNS record for all nodes, so that every search
appliance (master or replica) can be accessed via the same host name. In this case, you can set the
default URL to point to the shared hostname.
Tasks Performed on Replica Search Appliances
After GSA mirroring is configured, you perform most administrative tasks only on the master search
appliance. The following administrative tasks are performed on the replica search appliances:
• Installing a new license. All search appliances in the mirroring configuration must be licensed for
the same document count.
