Service使用referred和avileable固定會話到一個節點，當機後會切換到另一個節點
Service使用referred和avileable固定session連線到一臺資料庫伺服器上，這臺資料庫伺服器當機後會切換到另一臺資料庫伺服器上
管理員管理的DB裡，service分為：
- preferred instance：服務啟動的時候，在哪個例項上啟動，該例項就是preferred instance。
- available instance：服務所在的例項崩潰，叢集件會在另外一個available instance裡啟動該服務。

可以為服務新增多個preferred例項，這樣可以不需要available例項：
srvctl add service -d orcl -s srv2 -r orcl1,orcl2
srvctl start service -d orcl -s srv2
[oracle@node1 ~]$ srvctl status service -d orcl -s srv2
Service srv2 is running on instance(s) orcl1,orcl2
service可以只定義preferred例項，而不定義available例項。但是這樣就沒有HA了。
這樣當service所在的例項崩潰以後，該service不會failover到另外一個例項上去。
把srv1從orcl1上執行，轉移到orcl2上執行：
srvctl relocate service -d orcl -s srv1 -i orcl1 -t orcl2
管理員管理的DB裡，service分為：
- preferred instance：服務啟動的時候，在哪個例項上啟動，該例項就是preferred instance。
