QUESTION 112
Oracle Grid Infrastructure for a stand-alone server is installed on your production host before installing the Oracle Database server. The database and listener are configured by using Oracle Restart.
Examine the following command and its output:
$ crsctl config has
CRS-4622: Oracle High Availability Services auto start is enabled.
What does this imply?
A. When you start an instance on a high with SQL *Plus dependent listeners and ASM disk groups are automatically started.
B. When a database instance is started by using the SRVCTL utility and listener startup fails, the instance is still started.
C. When a database is created by using SQL* Plus, it is automatically added to the Oracle Restart configuration.
D. When you create a database service by modifying the SERVICE_NAMES initialization parameter, it is automatically added to the Oracle Restart configuration.
Correct Answer: B
(解析：Oracle Restart 確保根據組件依賴關系，以適當的順序啟動 Oracle 組件。例如，如果數據庫文件存儲在 Oracle ASM 磁盤組中，那么在啟動數據庫實例之前，Oracle Restart 確保啟動 Oracle ASM 實例并安裝所需的磁盤組。同樣，如果必須關閉組件，則 Oracle Restart 確保首先完全關閉依賴組件。Oracle Restart 還管理數據庫實例與 Oracle Net 偵聽器(偵聽器)之間的弱依賴性：當啟動數據庫實例時，Oracle Restart 嘗試啟動偵聽器。如果偵聽器啟動失敗，那么數據庫仍然啟動。如果偵聽器稍后失敗，Oracle Restart 不會關閉并重新啟動任何數據庫實例.)
