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 确保根据组件依赖关系，以适当的顺序启动 Oracle 组件。例如，如果数据库文件存储在 Oracle ASM 磁盘组中，那么在启动数据库实例之前，Oracle Restart 确保启动 Oracle ASM 实例并安装所需的磁盘组。同样，如果必须关闭组件，则 Oracle Restart 确保首先完全关闭依赖组件。Oracle Restart 还管理数据库实例与 Oracle Net 侦听器(侦听器)之间的弱依赖性：当启动数据库实例时，Oracle Restart 尝试启动侦听器。如果侦听器启动失败，那么数据库仍然启动。如果侦听器稍后失败，Oracle Restart 不会关闭并重新启动任何数据库实例.)
