NO.1 A solidDB disk-based database instance has been optimally running for six months and
starts to
experience major degradation in performance. Upon executing an overall DB status report
using ADMIN
COMMAND "status", it is noted that the value for index writes after last merge is at
20945876. Why would this be a probable cause of the performance degradation?
A. A large value for this counter signifies that the creation of indices, after a large batch insert
process, has been halted leading to excessive memory usage which can cause serious
performance issues.
B. A large value for this counter signifies that a large number of transactions are being
checkpointed which can cause serious performance issues.
C. A large value for this counter signifies that the multi-versioning storage tree is not being
flushed
to disk due to a long running transaction which can cause serious performance issues.
D. A large value for this counter signifies that a transaction performing a merge-join is
utilizing a
large amount of memory causing potential process paging/swapping leading to serious
performance issues.
