oracle11g dataguard中standby库文件坏块的修复过程
2015-10-19 21:01
399 查看
问题描述:
机房断电了,所以primary和standby库都是直接断电,然后我都设置了开机自启动oracle,所以第二天我来看的时候,primary和standby都启动了,归档日志也传输到standby了,但是日志应用后报错,有文件坏块,所以需要修复。
Google出来的解决方案:
shutdown the ADG standby, then mount it, and do media recovery until it has recovered past all the redo generated during the hot backup taken on the primary. Then stop media recovery, and open the database read only, and restart media recovery again.
采用解决方案:duplicate 远程恢复。
rman target sys/oraclepwd@XTTTESTDB.46 auxiliary sys/oraclepwd@XTTTESTDB.54
rman sys/你的sys密码@46是主库tns auxiliary sys/你的sys密码@54是备库tns
主库primary上check
从库standby上查询数据:
看到log sequence已经增长到38273,日志应该应用过来了,然后去查询数据临时表z_z_test数据也已经过来了,证明修复OK,成功了。
看到有ERROR信息:
Errors in file /oracle/app/oracle/diag/rdbms/pddgunq/powerdes/trace/powerdes_dbw0_14852.trc:
ORA-01186: file 201 failed verification tests
ORA-01157: cannot identify/lock data file 201 - see DBWR trace file
ORA-01110: data file 201: ‘/home/oradata/powerdes/temp01.dbf’
这种错误忽略就可以了,暂时不用考虑它们。

2)online在线的主库primary库压力比较小,进行远程恢复不影响primary的业务正常使用。
3)最后在晚上进行恢复
机房断电了,所以primary和standby库都是直接断电,然后我都设置了开机自启动oracle,所以第二天我来看的时候,primary和standby都启动了,归档日志也传输到standby了,但是日志应用后报错,有文件坏块,所以需要修复。
1,查看alert日志报警信息

3,看到是文件1_38052_821708334.dbf坏块,通过dbv检查

采用解决方案:duplicate 远程恢复。
4, 关闭standby库
4.1 开始关闭standby库
SQL> shutdown immediate ORA-01109: database not open Database dismounted. ORACLE instance shut down. SQL>
4.2 在standby上删除数据文件和控制文件
去数据文件目录和控制文件目录删除数据文件控制文件,如果一时不记得目录位置,可以通过以下方式查询select * from v$controlfile; select * from v$datafile;
4.3 再standby上删除归档目录下的旧归档文件
cd /data/oracle/oradgdata/standby_archive/ rm -rf *.dbf
4.4 在standby上启动nomount
SQL> startup nomount ORACLE instance started. Total System Global Area 5344731136 bytes Fixed Size 2213136 bytes Variable Size 3489663728 bytes Database Buffers 1811939328 bytes Redo Buffers 40914944 bytes SQL>
4.5 在primary上操作
主库上rman target sys/oraclepwd@XTTTESTDB.46 auxiliary sys/oraclepwd@XTTTESTDB.54
rman sys/你的sys密码@46是主库tns auxiliary sys/你的sys密码@54是备库tns

看到log sequence已经增长到38273,日志应该应用过来了,然后去查询数据临时表z_z_test数据也已经过来了,证明修复OK,成功了。
5,后台alert日志有错误信息

这种错误忽略就可以了,暂时不用考虑它们。

总结:
1)这种恢复必须在standby从库和主库的数据文件目录参数文件目录控制文件目录归档日志文件目录等等都相同的情况下才可以2)online在线的主库primary库压力比较小,进行远程恢复不影响primary的业务正常使用。
3)最后在晚上进行恢复
