总结:执行这个语句的结果是将缓存在library cache和data dictionary cache 中的sql,pl/sql和数据字典定义都从共享池中清除了 PS:在负载很重的生产库里执行flush shared_pool无异于自杀...慎用!
alter system flush shared_pool The FLUSH SHARED POOL clause lets you clear alldatafrom the shared pool in the system global area (SGA). The shared pool stores Cached data dictionary information and SharedSQLand PL/SQL areas for SQL statements, stored procedures, function, packages, and triggers...
Flush the Shared Pool To clear the whole shared pool you would issue the following command from a privileged user. ALTER SYSTEM FLUSH SHARED_POOL; It's a really brutal thing to do as all parsed SQL will be thrown away. The database will have to do a lot of work to warm up the shar...
Oracle数据库实现了buffer cache,shared pool等等内存区域的con_id化. Although consolidated into a single physical CDB, PDBs mimic the behavior of traditional non-CDBs. For example, a PDB administrator can flush the shared pool or buffer cache in the context of a PDB without affecting other PDBs ...

Ash size大小用于指定ash buffer(shared pool)。默认给定的是1048618 bytes,也就是1M。ASH工作采样是以Active Session为中心的。如果系统处理操作过于频繁,活跃用户会话数量很多,这样每次采样的数据量就会超过系统空闲状态。 随之而来的就是内存中ash buffer的填满,进而引发数据库强制回写数据,启动DBWR进程读写动作。DBWR...
