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？（）
- AConfigure Java Pool to cache the java objects.
- BConfigure Streams Pool to enable parallel processing.
- CIncrease Shared Pool size to cache more PL/SQL objects.
- DIncrease Database Buffer Cache size to increase cache hits.
- EConfigure Large Pool to be used by RMAN and shared server.
- FIncrease the total System Global Area （SGA） size to increase memory hits.
