Oracle10gEventsCONTROLF的改变 以下文字资料是由(全榜网网www.cha138.com)小编为大家搜集整理后发布的内容，让我们赶快一起来看一下吧！

　　《深入浅出Oracle》的一个读者在我的留言板上提出一个问题他说以下这条命令运行生成的跟踪文件和我书上的结果完全不同

alter session set events immediate trace name controlf level ;

　　注意一下他的输出:

DUMP OF CONTROL FILES Seq # = x e V STYLE FILE HEADER: Compatibility Vsn = = xa Db ID= = x ec d Db Name= TESTDB Activation ID= = x Control Seq= = x e File size= = x a File Number= Blksiz= File Type= CONTROL

　　原来是V Style的输出这是Oracle g的数据库我书中第一章的测试来自Oracle iR 由于events是Oracle的内部事件其行为在不同的版本中可能不同

　　在Oracle g中使用Level 的trace 得到以下的输出在这个输出中和Oracle i最大的不同是enabled threads部分增加了位图信息这个信息的增加我猜测是为了满足Oracle g Grid运算支持大量并行实例的需要 Level 及的trace将包含DUMP memory的信息可读性又有所降低了

　　记录一下还有待于进一步研究
