Using GBase CAPI load balancing creation to 8 a cluster of connection, the client should at least put a security group 8 a cluster node IP address to GBase CAPI, such as the host="192.168.1.1; 192.168.1.2 instead, "if a security group 8 a cluster only one node, the client should be passed to GBase CAPI cluster node: the host=" 192.168.1.1;" , semicolon after the IP address of a string is a must, using GBase CAPI load balance to create links to 8 a cluster, if there is no set "GBASE_OPT_USE_SERVER_BALANCE" option value (the value defaults to 0), then the GBase CAPI will between the IP address of the client to load balancing, if set "GBASE_OPT_USE_SERVER_BALANCE" option has a value of 1, then the GBase CAPI between 8 a cluster all nodes to load balance, the following is the use of GBase CAPI code sample of load balancing,
