<hr><p>由 macro 发布于: 2001-03-02 22:21</p><p> </p><p>If redo log file is corrupted in all mmebers ,the database administrator can solve this problem by reinitializing these log files:<br><br>eg.<br><br>ALTER DATABASE CLEAR LOGFILE '/DISK3/log2a.rdo';<br><br>Using this command is equivalent to adding and dropping an online redo log file.But you can issue this command <font color=red>even if there are only two log groups with one file each,and even if the cleared group is available but not archived.</font><br><br>Restrictions:<br>You can clear an online redo log file whether it is archived or not.However,when the redo log file is not archived ,you must include the keyword UNARCHIVED . This will make backups unusable if the online redo log file is needed for recovery.<br><br><br></p></td>
