 那麼，是我們的RAC配置有問題嗎?這兩類服務沒有ONLINE會不會影響RAC資料庫呢？我們又該如何啟動這些服務呢？

        其實，我們的RAC配置是沒有問題的，也不會影響資料庫正常運作。在預設情況下，其中的ora.gsd服務狀态是OFFLINE狀态，我們可不予理會，除非需要在11g Cluster上配置Oracle 9iR2的RAC。但凡以grid使用者執行crs_stat -t指令，看到Target和State這兩列的狀态均為OFFLINE，我們均可忽略。但是，我們該如何使之啟動呢？

        1 啟動ora.oc4j服務：

[[email protected] ~]$ srvctl start oc4j
OC4J could not be started

2 啟動ora.gsd服務：

[[email protected] ~]$ srvctl status nodeapps   
VIP rac1-vip is enabled
VIP rac1-vip is running on node: rac1
VIP rac2-vip is enabled
VIP rac2-vip is running on node: rac2
Network is enabled
Network is running on node: rac1
Network is running on node: rac2
GSD is disabled
GSD is not running on node: rac1
GSD is not running on node: rac2
ONS is enabled
ONS daemon is running on node: rac1
ONS daemon is running on node: rac2
eONS is enabled
eONS daemon is running on node: rac1
eONS daemon is running on node: rac2

從上,我們看到GSD服務狀态是disabled，接下來enable GSD服務：

[[email protected] ~]$ srvctl enable nodeapps -g
[[email protected] ~]$ srvctl status nodeapps 
VIP rac1-vip is enabled
VIP rac1-vip is running on node: rac1
VIP rac2-vip is enabled
VIP rac2-vip is running on node: rac2
Network is enabled
Network is running on node: rac1
Network is running on node: rac2
GSD is enabled
GSD is not running on node: rac1
GSD is not running on node: rac2
ONS is enabled
ONS daemon is running on node: rac1
ONS daemon is running on node: rac2
eONS is enabled
eONS daemon is running on node: rac1
eONS daemon is running on node: rac2

然後，啟動GSD服務

[[email protected] ~]$ srvctl start nodeapps -g
PRKO-2002 : Invalid command line option: -g
[[email protected] ~]$ srvctl start nodeapps 
PRKO-2421 : Network resource is already started on node(s): rac1,rac2
PRKO-2420 : VIP is already started on node(s): rac1,rac2
PRKO-2420 : VIP is already started on node(s): rac1,rac2
PRKO-2422 : ONS is already started on node(s): rac1,rac2
PRKO-2423 : eONS is already started on node(s): rac1,rac2
