|Topologies and Communication / Client/Server Configuration|
In a client/server configuration, by putting servers into logical member groups, you can control which servers your clients use and target specific servers for specific data or tasks. You can configure servers to manage different data sets or to direct specific client traffic to a subset of servers, such as those directly connected to a back-end database.
You can also define member groups to deploy JARs in parallel or to perform administrative commands across a member group.
#gemfire.properties groups=Portfolios,ManagementGroup1A server can belong to more than one member group. If specifying multiple group membership for the server, use a comma-separated list. Alternatively, if you are using the gfsh command interface to start up the server, provide a group name as a parameter:
gfsh>start server --name=server1 \ --group=Portfolios,ManagementGroup1
<pool name="PortfolioPool" server-group="Portfolios" ... <locator host="lucy" port="41111"> ... </pool> ... <region name="clientRegion" ... <region-attributes pool-name="PortfolioPool" ...
