Answer 1

可使用多种客户端连接GBase 8a集群，可在连接字符串中指定
ADO.NET:
String _ConnString = "server=192.168.0.2;failover=true;iplist=192.168.0.3;192.168.0.4;gclusterid=g1"
C API:
Host="192.168.1.1; 192.168.1.2"
JDBC:
String URL="jdbc:gbase://192.168.1.56/test?user=gbase&password=gbase20110531&failoverEnable
=true&hostList=192.168.1.57, 192.168.1.58&gcluster=gcl1"
ODBC：
"DRIVER=GBase 8a MPP Cluster ODBC 8.3 Driver;UID=gbase;PWD=gbase20110531;"
"SERVER={192.168.111.96; 192.168.5.212; 192.168.7.174; 192.168.7.173};"
"CONNECTION_BALANCE=1;GCLUSTER_ID=gcluster;"
"CHECK_INTERVAL=90;"
