很急啊，RAC的日志问题

evenliver

在某个ORACLE RAC系统运行的过程中，出现了ORA-00257 archiver error. Connect internal only, until freed.错误
我将archive目录下的归档文件删除了，在删除的过程中，不小心删除了一个归档日志文件yxbz_redo2_2.log。
将节点2的数据库实例shutdown，再重新open，只能到mount状态，alter database open时提示ORA-00341错误，标题中的日志＃错误
此问题该如何解决？请各位高手出手相助，不胜感激！

The first, if your database is in products env, don't make testing in that, following method can used in test env only!!!

Do you delete a non-current redo log?
if yes. you deleted log file is the redo log that not finish archive operation.now you can do following.

shutdown database immediate(must not be abort)
cold whole backup database(backup current env)

change cluster_database=false
connect the instance you deleted log
alter system archive log stop
change database to non-archive mode
you may startup database
or
startup mount
alter database open resetlog(make sure env, carefully)
if ok
shutdown database immediate
re-startup
cold whole backup database

startup mount
change it to archive mode at each node
alter database open
alter cluster_database=true(restore to RAC mode)
alter system archive log start (start archive operation)

FYI..

if you delete current redo log, so difficultly to restore, need modify "__"prefix oracle internal parameter, and not reference here .
