The Automatic Shared Memory Management feature is enabled for the PROD database. Currently， a lot of insert activity is taking place in the database， and the memory structures are allocated according to the database workload. As the workload reduces， you decide to perform batch jobs in the database. Which of the following initialization parameters are NOT automatically resized according to the new workload and continue to remain unchanged？（）A、 LOG_BUFFERB、 DB_CACHE_SIZEC、 JAVA_POOL_SIZED、 LARGE_POOL_SIZEE、 SHARED_POOL_SIZEF、 STREAMS_POOL_SIZE

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.
You are configuring the PROD database to use an internal tuning algorithm to monitor the performance of the workload. To achieve this configuration， you specify the following parameter settings in the SPFILE:// SGA_TARGET = 512M SHARED_POOL_SIZE = 256M Which two statements are true when modifying the SHARED_POOL_SIZE initialization parameter in the SPFILE？ （）A、 Modifying the SHARED_POOL_SIZE initialization parameter cannot be accomplished if the SGA_TARGET initialization parameter is set to a non-zero value.B、 Modifying the value of the SHARED_POOL_SIZE initialization parameter to zero is not allowed if the SGA_TARGET initialization parameter is set to a nonzero value.C、 Increasing the value of the SHARED_POOL_SIZE initialization parameter does not increase the shared pool component size. It sets the lower limit for the size of this component.D、 Decreasing the value of the SHARED_POOL_SIZE initialization parameter does not reduce the size of the shared pool component immediately. It sets the lower limit for the size of this component.E、 Increasing the value of the SHARED_POOL_SIZE initialization parameter immediately increases the shared pool component to the desired size by reallocating the additional memory from the auto-tuned memory components.F、 Decreasing the value of the SHARED_POOL_SIZE initialization parameter immediately shrinks the shared pool component to the desired size while reallocating the released memory to the memory components that are not auto-tuned.
