DATAGUARD 在线重建备库

环境: 

OS: CentOS 6.5 X64  DB: oracle 10.2.0.5

故障:之前由于错误激活备库主写导致主备日志同步，重建备库



1.关闭备库，删除数据文件及控制文件,redo文件

rm -rf *.log rm -rf *.ctl rm -rf *.dbf



2.主库备库

RMAN-03002: failure of backup plus archivelog command at 09/13/2014 17:32:18

ORA-19809: limit exceeded for recovery files

ORA-19804: cannot reclaim 2380478464 bytes disk space from 2147483648 limit

备份的时候出现此错误，这是由于备份的归档日志超过了数据库默认的备份空间容量(为flash_recovery_area).

SQL> show parameters db_recovery_file_dest



NAME                         TYPE     VALUE

------------------------------------ ----------- ------------------------------

db_recovery_file_dest               string     /u01/app/oracle/flash_recovery

                              _area

db_recovery_file_dest_size          big integer 2G

将主库的db_recovery_file_dest_size 扩大到4G



SQL> alter system set db_recovery_file_dest_size=4G scope=both;



System altered.



3.重建备库控制文件

RMAN> backup full database format='/u01/backup/%d_%s.dbf' plus archivelog delete input;
