View the Exhibit and examine the Instance Efficiency Percentages that you got on generating an Automatic Workload Repository (AWR) report for your online transaction processing (OLTP) database.
What can you deduce from this part of the AWR report? (Choose all that apply.)
A.
A low Library Hit % indicates that cursors are not being reused.
B.
A low Execute to Parse % indicates that most SQL statements are reusing the existing execution plans.
C.
A high In-memory Sort % indicates that most sorts are being done in memory, thereby causing the performance to degrade.
D.
A high Buffer Hit % indicates that required data blocks were found in the Buffer Cache memory, thereby avoiding expensive disk I/O.
