B. Enable automatic memory management

C. Set the PRE_PAGE_SGA parameter to true

Answer: B

答案解析：

使用自动内存管理来自动扩大SHARED_POOL_SIZE的尺寸。

[oracle@rtest ~]$ oerr ora 4031

04031, 00000, "unable to allocate %s bytes of shared memory ("%s","%s","%s","%s")"

// *Cause:  More shared memory is needed than was allocated in the shared

//          pool or Streams pool.

// *Action: If the shared pool is out of memory, either use the

//          DBMS_SHARED_POOL package to pin large packages,

//          reduce your use of shared memory, or increase the amount of

//          available shared memory by increasing the value of the

//          initialization parameters SHARED_POOL_RESERVED_SIZE and 

//          SHARED_POOL_SIZE.

//          If the large pool is out of memory, increase the initialization

//          parameter LARGE_POOL_SIZE.  

//          If the error is issued from an Oracle Streams or XStream process,

//          increase the initialization parameter STREAMS_POOL_SIZE or increase

//          the capture or apply parameter MAX_SGA_SIZE.
