A Connection Group consists of a number of external servers
that the Enterprise Gateway connects to (for example, RSA Access Manager servers for
authorization). The Enterprise Gateway attempts to connect to all the servers in the
group in a round-robin fashion, therefore providing a high degree of failover.
If one or more servers are unavailable, the Enterprise Gateway can still connect to
an alternative server.
The Enterprise Gateway attempts to connect to the listed servers according to
the priorities assigned to them. For example, assume there are two High
priority servers, one Medium priority server, and one Low priority server
configured. Assuming the Enterprise Gateway can successfully connect to the two
High priority servers, it alternates requests between these two servers only
in a round-robin fashion. The other group servers are not used. However, if
both High priority servers become unavailable, the Enterprise Gateway then tries to
use the Medium priority server, and only if this fails is the Low priority
server used.
Connection Groups are available in Policy Studio on the External
Connections tab according to the filter from which they are available.
For example, Connection Sets under the RSA ClearTrust Connection Sets
node are available in the RSA Access Manager filter. For more details, see the
RSA Access Manager Authorization topic.
