今天 redo 的路径不对, 导致 dataguard 备库的 不能open:ORA-01275: 自动进行备用文件管理时, 不允许进行 ADD LOGFILE 操作
今天 redo 的路径不对, 导致 dataguard 备库的 不能open:
ORA-01275: 自动进行备用文件管理时, 不允许进行 ADD LOGFILE 操作
下面来说一下:
先看一下备库的信息:
SQL> select switchover_status from v$database;
SWITCHOVER_STATUS
--------------------
RECOVERY NEEDED
SQL> select database_role , open_mode from v$database;
DATABASE_ROLE OPEN_MODE
---------------- ----------
PHYSICAL STANDBY MOUNTED
SQL> alter database recover managed standby database cancel;
alter database recover managed standby database cancel
*
第 1 行出现错误:
ORA-16136: ?????????
SQL> alter database recover managed standby database disconnect from session;
数据库已更改。
SQL> alter database open;
alter database open
*
第 1 行出现错误:
ORA-16004: ?????????
ORA-01152: ?? 1 ???????????
ORA-01110: ???? 1: 'C:\Oracle\PRODUCT\10.2.0\ORADATA\SHENG\SYSTEM01.DBF'
检查一下alert 日志:
发现undo 文件没有从主库上copy 到备库:
----------------
把primary 上的undospace copy 到standby 上后:
SQL> alter database recover managed standby database disconnect from session;
数据库已更改。
SQL> alter database open;
alter database open
*
第 1 行出现错误:
ORA-01154: ????????????, ??, ?????
检查一下备库的alert 日志:

看一下备库上的redo :
SQL> set wrap off
SQL> select * from v$logfile;
行将被截断

1 ONLINE D:\ORACLE\PRODUCT\10.2.0\ORADATA\SHENG\REDO01.LOG
很明显,备机上没有相关联的路径:
好,,下面进行redo log 的重建和 standby redo log 的重建:
SQL> alter database drop logfile group 1;
alter database drop logfile group 1
*
第 1 行出现错误:
ORA-01156: ??????????????
ORA-01156:
ORA-01275: 自动进行备用文件管理时, 不允许进行 ADD LOGFILE 操作。
关闭数据库,在开启状态下。将auto修改成manual
SQL>alter system set standby_file_management=manual
alter database rename 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\SHENG\REDO03.LOG' to 'C:\ORACLE\PRODUCT\10.2.0\ORADATA\SHENG\REDO03.LOG';
alter database rename 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\SHENG\REDO01.LOG' to 'C:\ORACLE\PRODUCT\10.2.0\ORADATA\SHENG\REDO01.LOG';
alter database rename 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\SHENG\REDO02.LOG' to 'C:\ORACLE\PRODUCT\10.2.0\ORADATA\SHENG\REDO02.LOG';
在添加:
SQL> alter database add standby logfile group 4 ('C:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\redo04.log') size 50m;
SQL> alter database add standby logfile group 5 ('C:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\redo05.log') size 50m;
SQL> alter database add standby logfile group 6 ('C:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\redo06.log') size 50m;
SQL> alter database add standby logfile group 7 ('C:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\redo07.log') size 50m;
SQL> select * from v$logfile;
GROUP# STATUS TYPE MEMBER
