新手入门,请多指教!我在看9i的书时,看到DBWn进程写数据文件的条件中有 drop or truncate table.但是在看10g的书中却改成了 A segment is droped.在一个练习题的解释中,则明确说DBWn does not write data to the datafiles when a table is dropped from the database. When dropping a table from the database,only the redo is written to the redo log buffer.请问各位大哥,到底删除表会不会引发写数据文件?[ 本帖最后由 wmlm 于 2008-1-4 17:14 编辑 ]
