Your database has the SRV1 service configured for an application that runs on middle-tier application server. The application has multiple modules. You enable tracing at the service level by executing the following command:
SQL > exec DBMS_MONITOR.SERV_MOD_ACT_TRACE_ENABLE (‘SRV1’);
The possible outcome and actions to aggregate the trace files are as follows:
1. The command fails because a module name is not specified.
2. A trace file is created for each session that is running the SRV1 service.
3. An aggregated trace file is created for all the sessions that are running the SRV1 service.
4. The trace files may be aggregated by using the trcess utility.
5. The trace files be aggregated by using the tkprof utility.
Identify the correct outcome and the step to aggregate by using tkprof utility?()

A. 1
B. 2 and 4

9.多项选择题

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?()

A. Using 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.
B. Using 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.
C. Using a partitioned view that does a UNION ALL query on the partitions of the warehouse fact table, which retains the existing local partitioned column.
D. Converting the partitioned table to a partitioned view that does a UNION ALL query on the monthly tables, which retains the existing local partitioned column
E. Using 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.
F. Using 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.

10.多项选择题Which two statements are true when row archival management is enabled?()

B. The ORA_ARCHIVE_STATE column is updated manually or by a program that could reference activity tracking columns, to indicate that a row is no longer considered active.
C. The ROW ARCHIVAL VISIBILITY session parameter defaults to active rows only.
D. The ORA_ARCHIVE_STATE column is visible if referenced in the select list of a query.
