多选题A warehouse fact table in your Oracle 12c Database is range-partitioned by month and accessed frequently with queries that span multiple partitions The table has a local prefixed, range partitioned index. Some of these queries access very few rows in some partitions and all the rows in other partitions, but these queries still perform a full scan for all accessed partitions. This commonly occurs when the range of dates begins at the end of a month or ends close to the start of a month. You want an execution plan to be generated that uses indexed access when only a few rows are accessed from a segment, while still allowing full scans for segments where many rows are returned. Which three methods could transparently help to achieve this result?（）AUsing a partial local Index on the warehouse fact table month column with indexing disabled to the table partitions that return most of their rows to the queries.BUsing a partial local Index on the warehouse fact table month column with indexing disabled for the table partitions that return a few rows to the queries.CUsing a partitioned view that does a UNION ALL query on the partitions of the warehouse fact table, which retains the existing local partitioned column.DConverting the partitioned table to a partitioned view that does a UNION ALL query on the monthly tables, which retains the existing local partitioned columnEUsing a partial global index on the warehouse fact table month column with indexing disabling for the table partitions that return most of their rows to the queries.FUsing a partial global index on the warehouse fact table month column with indexing disabled for the table partitions that return a few rows to the queries.

execute the command， ALTER SESSION KILL ..， to kill the blocking sessionB
execute the DBMS_SESSION.KILL_SESSION procedure to kill the blocking sessionC
execute the command， ALTER SYSTEM KILL SESSION ..， to kill the blocking sessionD
execute the command， ALTER SESSION UNLOCK ..， to release the lock for the blocking sessionE

单选题For the V$SESSION_LONGOPS view， you find that some of the database users have long-running queries that consume a lot of CPU time. This causes performance problems for other users in the database， who have much shorter queries. You would like to make sure that the users with large queries do not use all the CPU time， but you still do not want to terminate them with an error message. Which method would you follow to achieve this？（）A
Set the CPU time per call in the users profile.B
Set the CPU time per session in the users profile.C
Set the CPU levels for the user’s group using Resource Manager.D
Set the TIMED_STATISTICS parameter to TRUE in the parameter file.
