查看集群資源信息
[12:59:42oracle@node2 ~]srvctl config database -d dba -a

查看連接信息
[13:01:55oracle@node2 ~]srvctl config database -d dba -t
Example client-side TNS entry for service rac:
rac = (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=db_vip)(PORT=dedicated_port))(CONNECT_DATA=(SERVICE_NAME=rac.wang.com)(FAILOVER_MODE=(TYPE=SELECT)(METHOD=BASIC))))
Example client-side TNS entry for service name:
name = (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=db_vip)(PORT=dedicated_port))(CONNECT_DATA=(SERVICE_NAME=name.wang.com)(FAILOVER_MODE=(TYPE=SELECT)(METHOD=BASIC))))

查看監聽信息
[13:05:57oracle@node2 ~]srvctl config listener -n node2
node2 LISTENER_NODE2
[13:06:15oracle@node2 ~]
[13:06:16oracle@node2 ~]srvctl config listener -n node1
node1 LISTENER_NODE1
查看數據庫狀態
[13:08:40oracle@node2 ~]srvctl status database -d dba
Instance null1 is running on node node1
Instance null2 is running on node node2
[13:08:43oracle@node2 ~]srvctl status database -d dba -v
Instance null1 is running on node node1 with online services rac name
Instance null2 is running on node node2 with online services rac name
查看監聽狀態
[13:09:27oracle@node2 ~]srvctl status instance -d dba -i null1,null2
Instance null1 is running on node node1
Instance null2 is running on node node2

查看節點ASM狀態
[13:11:47oracle@node2 ~]srvctl status asm -n node1
ASM instance +ASM1 is running on node node1.
[13:12:26oracle@node2 ~]srvctl status asm -n node2
ASM instance +ASM2 is running on node node2.
測試TAF
設定服務TAF模式為BASIC
RAC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = node2-vip)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = rac.wang.com)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 180)
(DELAY = 5)
)
)
)
