Users complain about the performance of an Oracle database-based application. You are requested to investigate. From Grid Control, you immediately infer that one of the cluster database instances and one of the cluster ASM instances are currently unavailable. You also see that the host where the instance belongs was recently rebooted due to an unknown reason.
Using Grid Control, you restart the instance and performance rapidly improves. You want to determine the cause of the instance startup failure after system boot, and you check the resource profiles on both the database and ASM instances involved.
Why was the instance not started by CRS?
A.
The instance was started by CRS after the system was rebooted, but someone stopped it from within SQL*Plus.
B.
The database instance autostart attribute is set to a value, thus preventing CRS from starting it after a system reboot.
C.
The instance was not started by CRS because its target state was set to “offline” a while before the system was rebooted.
D.
The instance was started by CRS but due to multiple instance failures CRS disabled the database instance, thereby preventing further restarts.
E.
The database instance could not be started by CRS because this instance depends on an ASM instance, whose autostart attribute indicates that CRS should not start this ASM instance after system boot.
