我们进一步来讨论一下shared pool的处理: 先进行相应查询，获得测试数据: [oracle@jumper udump]$ sqlplus "/ as sysdba" SQL*Plus: Release 9.2.0.3.0 - Production on Thu Aug 26 10:21:54 2004 Copyright (c) 1982, 2002, Oracle Corporation.

BUCKET 4581: LIBRARY OBJECT HANDLE: handle=52d9ea28 name=select * from emp hash=9de011e5 timestamp=08-26-2004 10:24:43 ==>这个hash正是v$sql中该sql语句的hash_value值 namespace=CRSR
