oracleRACclient-sideTAF&&server-sideTAF(四)

如果当Rac1失效（节点关闭），那么select将再次移动到Rac2上来

SQL> r
  1* select inst_id,username,failover_type,failover_method,failed_over from gv$session where username='SYSTEM'

   INST_ID USERNAME                       FAILOVER_TYPE FAILOVER_M FAI
---------- ------------------------------ ------------- ---------- ---
         2 SYSTEM                         SELECT        BASIC      YES

到了11G R2 使用scan和server-side TAF是最佳选择。

That’s all！！！！！
