View the Exhibit that sets the threshold for the Current Open Cursors Count metric.Why is the Significance Level threshold type not available in the threshold setting?() A. because AWR baseline is not enabledB. because Current Open Cursors Count is not a basic metricC. because the STATISTICS_LEVEL parameter is set to BASICD. because the AWR baseline is a system-defined moving window baseline
View the Exhibit to examine the metrics with a threshold.Which statement is true regarding the Number of Transactions (per second) metric?() A. Oracle uses statistical relevance to determine when an adaptive threshold has been breached for the metric.B. The statistics for the metric values observed over the baseline time period are not examined to determine threshold values.C. Oracle determines when an adaptive threshold has been breached based on the maximum value captured by the baseline.D. The total concurrent number of threshold violations, which must occur before an alert is raised for the metric, has been set to zero.
共用题干Just one hour's listening to an MP3 player can damage hearing,claim scientists.It causes temporary changes in hearing sensitivity which may lead to long-term harm,according to a new study.The findings show over -stimulation of hair cells within the ear occurs even at varying volume levels for short periods of time.The study of almost 60 young people carried out by researchers at Ghent University,Belgium,is published in the Archives of Otolaryngology -Head&Neck Surgery journal.It follows previous warnings from doctors that using MP3 players at high volumes with earphones that fit into the ear canal could lead to loss of hearing. In the latest study,21 people aged 19 to 28 years were exposed to pop and rock music using MP3 players at varying volumes for one hour. A second group of 28 men and women were a control group who were not exposed to MP3 music.Hearing tests were carried out before and after the exposure,which found significant threshold or emission shifts were observed between almost every session of the noise exposure group compared with the control group.Lead researcher Hannah Kempler said:Excessive noise exposure can lead to metabolic and mechanical effects resulting in alterations of the structural elements of the inner ear that contains auditory sensory cells or"hair cells".The European Commission has warned up to 10% of 30-year-old would have to wear a hearing device within the next decade because they listen to music too loudly through headphones.Surveys showed more than 90% of young people in Europe and the U.S.used MP3 players,often for several hours a day at maximum volume.Hearing experts recommend the 60/60 rule一listening to MP3 players for no more than 60 minutes at a time at 60% of maximum volume.Concern among EU health and safety officials has led to plan to ensure all MP3 players have the same maximum volume of 85 decibels(dB)一although users may be able to individually override it at their own risk. MP3 player can't damage hearing when one listens to MP3 music for only 60 minutes.A:Right B:Wrong C: Not mentioned

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.
