Oracle RAC Load Balance , Fail Over測試

配置server端的tnsnames.ora,首先來看各例項的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
