While an electrician was adding additional circuits for the Data Center, the system running the Database inadvertently powered down. The fallover of the service IP labels and volume groups to the hot standby node completed as expected; however, the database did not start. The database log file indicated that the database was already started. What is the most likely cause of this problem?() A、 The shared logical volumes and filesystems did not have database permissions.B、 There was a test instance running on the standby system that must be shutdown.C、 The tablespaces had an indicator indicating that the database had not shutdown properly.D、 The startup script for the highly available instance did not first perform cleanup operations.
