ORA-00349|激活 ADG 备库时遇到的问题及处理方法 目录
  • 重建备库 redolog
  • 重建备库控制文件解决
  • 找到最终问题所在
  • 最终激活备库

近日有一套实时同步的 ASM 管理的单机 11204 ADG 备库，由于业务需要，想要脱离主库的约束，想激活拉成读写库直接升级成 ASM 管理的 19C，闪回快照模式无法满足要求，只能 ALTER DATABASE ACTIVATE STANDBY DATABASE 强制切成可读写的主库。说干就干，先将其切成主库，升级过程等下次在一起讨论。

--主库
--主库设置为 defer, 取消备库日志应用，关库启动到 mount 状态进行。
show parameter log_archive_dest_state_2
alter system set log_archive_dest_state_2=defer scope=both sid='*';
 
--备库
alter database recover managed standby database cancel;
shu immediate
startup mount
 
--强制拉成主库，很遗憾报错 ORA-00349
SQL> ALTER DATABASE ACTIVATE STANDBY DATABASE;

ERROR at line 1:
ORA-00349: failure obtaining block size for '+JIEKE_DATA'
ORA-15001: diskgroup "JIEKE_DATA" does not exist or is not mounted
ORA-15001: diskgroup "JIEKE_DATA" does not exist or is not mounted

使用 ACTIVATE 命令想强制拉成主库，很遗憾如下图报错 ORA-00349。alert 日志中发现有很多清理 redo log 的报错，“ORA-00313: open failed…”无法打开日志组 5、6、23，于是查看日志组成员确实发现 redolog 创建的有问题，member 成员显示的为不存在的磁盘组 “+JIEKE_DATA” 而不是具体路径，真是存在的磁盘组“+JIEKER_DATA”。这就是问题所在，redolog 创建错误，切成主库时 redolog 又是必须的，故报错了，那么现在就是将这个错误的 redolog 重建，问题就会得到解决。但实际上不是这样的，折腾了好久也没解决，继续往下看。

重建备库 redolog

那么，这里将上演的是重建备库 redolog 的相关 *** 作步骤。

重建备库控制文件解决

第二日早晨，睡醒之后头脑清晰想到备库既然无法删除，那主库肯定是可以删除的。通过主库删除日志组 6、23 之后，再重建一个备库的控制文件就可以解决。这样也很简单，主库删除备库有问题的两组日志组后使用 rman 备份一个备库的 控制文件，然后 scp 到备库，备库重启到 nomount 恢复控制文件，启动到 mount 就好了。

--主库：
SQL> alter database drop logfile group 6;
Database altered.
SQL> alter database drop logfile group 23;
Database altered.
 
rman target /

重建控制文件后恢复的备库中就没有了错误的磁盘组，但这样时间长一些则备库日志应用会延迟，因为 standby_log 日志状态全部为 UNASSIGNED 的。需要重建备库 standby redolog 日志组后它的状态才会变成 ACTIVE。
取消日志应用，修改参数为 manual 删除原有日志组，重建日志组改回参数应用日志同步进程即可。

找到最终问题所在

完成重建后，本以为已经万事大吉了，但一开库应用日志却发现后台日志中所有 redolog 日志组都被清理了。这才意识到问题的根源所在，立马查看了路径相关的参数发现 db_create_online_log_dest 参数设置错误，导致创建出了错误的磁盘组。

但是现在修改完参数所有的日志组成员也都出现在错误的磁盘组了，因为有了当前日志组 4、10 占用了，重建日志组也行不通，故只能再次重建备库控制文件了。以上主库备份控制文件传到备库恢复的过程再来一遍即可。

最终激活备库

再一次重建后正常恢复同步，然后关闭实例启动到 mount 状态，激活 ADG 备库，重启验证即可。
