第5题：

You find that the database performance degrades while you backup the PROD database using Recovery Manager （RMAN）. The PROD database is running in shared server mode. The database instance is currently using 60% of total operating system memory. You suspect the shared pool fragmentation to be the reason. Which action would you consider to overcome the performance degradation？（）

• A、Configure Java Pool to cache the java objects.
• B、Configure Streams Pool to enable parallel processing.
• C、Increase Shared Pool size to cache more PL/SQL objects.
• D、Increase Database Buffer Cache size to increase cache hits.
• E、Configure Large Pool to be used by RMAN and shared server.
• F、Increase the total System Global Area （SGA） size to increase memory hits.

第6题：

You configured the large pool for Oracle backup and restore operations. As a result， which component would require less memory？（）

• A、 streams pool
• B、 shared pool
• C、 log buffer
• D、 keep buffer cache
• E、 recycle buffer cache

第7题：

You are analyzing how Oracle processes user statements. SQL and PL/SQL parse information is stored in which of the following database memory areas? （）

• B、Row cache
• C、Dictionary cache 
• D、Large area 
• E、Buffer cache

第8题：

Your database supports a DSS workload that involves the execution of complex queries: Currently, the library cache contains the ideal workload for analysis. You want to analyze some of the queries for an application that are cached in the library cache. What must you do to receive recommendations about the efficient use of indexes and materialized views to improve query performance?（）

• B、Run the Automatic Workload Repository Monitor (ADDM).
• C、Create an STS that contains the queries cached in the library cache and run the SQL Performance Analyzer (SPA) on the workload captured in the STS.
• D、Create an STS that contains the queries cached in the library cache and run the SQL Access Advisor on the workload captured in the STS.
