We tested the architecture using a prototype DFMS built in Visual Basic and executed in a Windows environment, using a resident application program as a temporary extension to their operating system-our current implementation is a parasitic, not native, DFMS. However, nothing precludes one from ...
We could either usefs.open()to open, read or write files;fs.readFile()just to read, orfs.writeFile()to write to the file. Before using fs.open() to create a file, we need to load the fs class module to access the file system, only then we'll be able to do such operations. ...

跟踪文件通常都是因为通过DBMS_MONITOR(在Oracle Database 9i Relese 2)及更早版本中则是ALTER SESSION SET SQL_TRACE=TRUE启用了跟踪的结果,或者是通过10046事件使用扩展的跟踪工具生成的,如下这些跟踪文件包含与诊断和性能有关的信息。它们对于了解数据库应用的内部工作有着非凡的意义。在一个正常运行的数据库中,...
