Question

关于插入Oracle数据库的问题...我有代码示例（如下），此代码将500条记录插入到db ..但是插入500条记录需要3分钟...目前为止因为我知道表有索引，服务器是全新的，非常快，我做了一些关于网络速度的测试，一切都好，所以我怀疑是我的＃34;插入代码＆＃34 ;不是很好......有没有一种方式可以加速＆＃34;加速＆＃34;插入或者还有其他我忽略的东西......所以任何建议都很好......谢谢！

这是＆＃34;插入＆＃34;代码示例：

如果您在等待事件运行时看到等待事件并且没有什么是明显的，那么最佳方法是跟踪会话。你会在那里找到你的答案。有几种跟踪会话的方法。我使用的那个（假设我不需要登录触发器立即启用它）是：

1）找到会话的spid
  从v $ session s中选择spid，v $ process p其中s.paddr = p.addr和s.sid ='＆amp; sid';

2）启用oradebug跟踪（as sysdba）
  oradebug setospid＆amp; spid
  oradebug事件10046追踪名称背景永远，等级12

3）找到跟踪文件（检查diag目录。跟踪文件将在文件名中包含spid） - 在linux中，通常“ls -lrt”会将其显示为显示列表中的最后一个文件<登记/>
4）如果要进行汇总，可以在跟踪文件上运行tkprof。如果您需要原始详细信息，请查看“.trc”文件（它将显示所发生的一切，时间和发生的顺序）

5）禁用跟踪（如果会话未注销）
  oradebug setospid＆amp; spid   oradebug事件10046跟踪名称上下文关闭
