ORA-00344: unable to re-create online log

今天做RMAN恢复，数据库为10.2.0.5，从单机到RAC。

打开数据库的时候出现下面的错误。

 RMAN> alter database open resetlogs;
 RMAN-00571: ===========================================================
 RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
 RMAN-00571: ===========================================================
 RMAN-03002: failure of alter db command at 08/10/2015 09:53:07
 ORA-00344: unable to re-create online log '/oradata/outdb/redo01.log'
 ORA-27040: file create error, unable to create file
 Linux-x86_64 Error: 2: No such file or directory

查看当前系统redo log路径

 SQL> select * from v$logfile;

     GROUP# STATUS TYPE MEMBER IS_
 ---------- ------- ------- -------------------------------------------------- ---
          1 ONLINE /oradata/outdb/redo01.log NO
          2 ONLINE /oradata/outdb/redo02.log NO
          3 ONLINE /oradata/outdb/redo03.log NO
          4 ONLINE /oradata/outdb/redo04.log NO
          5 ONLINE /oradata/outdb/redo05.log NO
          6 ONLINE /oradata/outdb/redo06.log NO
          7 ONLINE /oradata/outdb/redo07.log NO
          8 ONLINE /oradata/outdb/redo08.log NO
          9 ONLINE /oradata/outdb/redo09.log NO
         10 ONLINE /oradata/outdb/redo10.log NO

查询结果可以看出日志路径不是ASM里面的路径，所以需要对路径进行修改。
执行下面的语句修改路径：

SQL:

 SQL> alter database rename file '/oradata/outdb/redo01.log' to '+DATADG/otdb/onlinelog/redo01.log';
 alter database rename file '/oradata/outdb/redo02.log' to '+DATADG/otdb/onlinelog/redo02.log';
 alter database rename file '/oradata/outdb/redo03.log' to '+DATADG/otdb/onlinelog/redo03.log';
 alter database rename file '/oradata/outdb/redo04.log' to '+DATADG/otdb/onlinelog/redo04.log';
 。。。。。。。。。

修改完之后再重新打开数据库，打开正常。
open

 [oracle@otdb1 ~]$ sqlplus / as sysdba

 Database altered.

最新的日志路径：
v$logfile

 SQL> select * from v$logfile;

     GROUP# STATUS TYPE MEMBER IS_

          1 ONLINE +DATADG/otdb/onlinelog/redo01.log NO
          2 ONLINE +DATADG/otdb/onlinelog/redo02.log NO
          3 ONLINE +DATADG/otdb/onlinelog/redo03.log NO
          4 ONLINE +DATADG/otdb/onlinelog/redo04.log NO
          5 ONLINE +DATADG/otdb/onlinelog/redo05.log NO
          6 ONLINE +DATADG/otdb/onlinelog/redo06.log NO
          7 ONLINE +DATADG/otdb/onlinelog/redo07.log NO
          8 ONLINE +DATADG/otdb/onlinelog/redo08.log NO
          9 ONLINE +DATADG/otdb/onlinelog/redo09.log NO
         10 ONLINE +DATADG/otdb/onlinelog/redo10.log NO

这次过程也提醒我以后做rman恢复时要注意日志的路径，提前修改，避免后面的错误。
