本文介绍了解决由DostoTemp表引起的性能问题的方法。通过删除特定模式的全局临时表统计数据，并调整CST_GATHER_STATS配置来避免不必要的统计信息收集，以此减轻对系统性能的影响。

Do stat on global temp will bring performance issue, so the following action is to delete them.

Deleted the statistics on the following below global temp tables: 

  DBMS_STATS.DELETE_TABLE_STATS ( ownname => 'BOM', tabname =>'*_TEMP'); 

  DBMS_STATS.DELETE_TABLE_STATS ( ownname => 'BOM', tabname =>'*_TEMP'); 

  DBMS_STATS.DELETE_TABLE_STATS ( ownname => 'BOM', tabname =>'**_TEMP'); 

  DBMS_STATS.DELETE_TABLE_STATS ( ownname => 'BOM', tabname =>'**_TEMP'); 

  DBMS_STATS.DELETE_TABLE_STATS ( ownname => 'BOM', tabname =>'**_TEMP'); 

Profile CST_GATHER_STATS=N (**: Cost update- Gather Statistics) - This
 will prevent stats

gathering on the GTT tables that might cause the performance issue. 

确定要放弃本次机会？

性能受到系统架构的巨大影响, 而本书并没有涉及在高性能做为一个必需的设计约束时有哪些典型的场景以及可选的架构方案. 本书将内容限定在具体的产品和调优技术上, 或者, 技巧上. 架构决定性能的级别, 需要尽早确定必需的性能级别.书中提议不要把web应用看成单个application, 而是"分布式组件集合". 通常讲性能调优的书, 都是按照应用的不同层来分别讲述, 比如客户端性能, 服务端性能, 数

先说下tmp_table_size吧：它规定了内部内存临时表的最大值，每个线程都要分配。（实际起限制作用的是tmp_table_size和max_heap_table_size的最小值。）如果内存临时表超出了限制，MySQL就会自动地把它转化为基于磁盘的MyISAM表，存储在指定的tmpdir目录下，默认: mysql> show variables like "tmpdir";
