ORACLE RAC資料庫連線方式

方法1：適合中介軟體等jdbc等連線方法,本示例為thin方式

url="jdbc:oracle:thin:@(description =

(load_balance = no)

(address = (protocol =tcp)(host = dtydb3-vip)(port = 1521))

(address = (protocol =tcp)(host = dtydb4-vip)(port = 1521))

(address = (protocol =tcp)(host = dtydb5-vip)(port = 1521))

(address = (protocol =tcp)(host = dtydb6-vip)(port = 1521))

(connect_data =

(service_name = srv_kfpb1)

同時需要修改/etc/hosts檔案，新增如下內容

#vip

10.4.×.* dtydb3-vip

10.4.×.* dtydb4-vip

10.4.×.* dtydb5-vip

10.4.×.* dtydb6-vip

方法2：一般用於sqlplus、plsql等客戶端工具

$oracle_home/network/admin/tnsnames.ora檔案中新增如下內容

tydb_kfpb1 =

(description =

(load_balance = no)

(address = (protocol =tcp)(host = 10.4.×.*)(port = 1521))

(address = (protocol =tcp)(host = 10.4.×.*)(port = 1521))

(address = (protocol =tcp)(host = 10.4.×.*)(port = 1521))

(address = (protocol =tcp)(host = 10.4.×.*)(port = 1521))

(connect_data =

(service_name= srv_kfpb1)

然後直接使用tydb_kfpb1進行連線

備註：黃色部分修改為自己需要的服務名
