oracle rac fail,Oracle RAC Load Balance , Fail Over测试
配置server端的tnsnames.ora,首先來看各實例的remote_listener和local_listener情況:
rac1:
SQL> show parameter listener
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string LISTENER_RAC1
mts_listener_address string
mts_multiple_listeners boolean FALSE
remote_listener string LISTENERS_RAC
rac2:
SQL> show parameter listener
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string LISTENER_RAC2
mts_listener_address string
mts_multiple_listeners boolean FALSE
remote_listener string LISTENERS_RAC
rac3:
SQL> show parameter listener
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string LISTENER_RAC3
mts_listener_address string
mts_multiple_listeners boolean FALSE
remote_listener string LISTENERS_RAC
