While Monitoring the space usage in your database that is in ARCHIVELOG mode you observed that the flash recovery area does not have enough free space to accommodate any more files and you do not have necessary permissions to add more space to it. Identify the two events that can occur in the event of a log switch？（）
A
An entry is created in the alert log file and the database instance continues to function normally
B
The log switch hangs occur for transactions until free space is available in the flash recovery area
C
The Oracle database server deletes a file that is on the obsolete file list to make free space in the flash recovery area
D

考题
While setting up the threshold for tablespace space usage metrics for one of your tablespaces， you define the critical threshold as 60% and warning threshold as 75%. What would be the result of this setting？（）A、 It would result in an error because the warning threshold cannot be more than the critical threshold.B、 The warning threshold is ignored and alerts would be generated when space usage exceeds the critical threshold.C、 The critical threshold is ignored and alerts would be generated when space usage exceeds the warning threshold.D、 Both threshold values are used and alerts are generated when space usage exceeds the respective threshold values.
考题
The warning and critical threshold values have been set to 85% and 97%， respectively， for one of the tablespaces. The current tablespace space usage is 54%.

Which statement is true？（）A、 The new setting would be applied but no alerts would be raised immediately.B、 The new setting would be applied and an alert would be raised immediately.C、 The new setting would be ignored because the tablespace space usage is more than the specified threshold value.D、 The new setting would cause an error because the tablespace space usage is more than the specified threshold value.
