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.
