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.
单选题You are a professional level SQL Sever 2008 Database Administrator in an international corporation named Wiikigo. You are experienced in managing databases in an enterprise-level organization, optimizing and sustaining the database life cycle. In the company, your job is to implement solutions on security, troubleshooting, deployment and optimization. A SQL Server 2008 infrastructure is managed by you. A maintenance strategy should be designed for a mission-critical database, and a large table named Orders is contained by the database. Index maintenance operations are contained in the design plan. When you design the strategy, the facts listed below should be taken into consideration. First, the users continuously access to the Orders table in the database. Secondly, a column of the xml data type is contained by Orders table. Thirdly, the new rows are regularly added to the Orders table. Fourthly, the average fragmentation for the clustered index of the Orders table is no more than 2 percent. A strategy should be designed to have the performance of the queries on the table optimized. Which action will you perform?()AThe clustered index of the Orders table should be dropped.BThe clustered index of the Orders table offline should be rebuilt once a month.CThe clustered index of the Orders table should be excluded from scheduled reorganizing or rebuilding operations.DThe clustered index of the Orders table should be reorganized by reducing the fill factor.
