当使用共享服务模式时,Private Sql Area位于Library Cache中
而Private Sql Area分为 The run-time area 和 The persistent area
1、information or metadata: Data Dictionary Cache
2、 This area contains query execution state information.
3、The server result cache contains the SQL query result cache and PL/SQL function result cache
4、The library cache holds executable forms of SQL cursors, PL/SQL programs, and Java classes.
5、 Redo entries contain
