难见的oracle 9i恢复—2023年

发表于 2023 年 5 月 15 日 由 惜分飞

时过境迁,以前恢复大量oracle 8/9版本的库,现在一套oracle 9i的库都比较稀奇了.今天恢复客户一套9.2.0.6的aix环境rac库,通过分析确认主要问题:
1. 重建控制文件，resetlogs库遗漏数据文件
missing_dbf

2. 数据库启动主要报错ORA-600 2663和ORA-600 kclchkblk_4

根据客户文件名称的规则,推算出来84号文件实际的文件名(因为使用的是lv[aix的hacmp管理的lv的裸设备方式]),通过dbv确认文件无坏块

udev_start导致vip漂移(常见情况:rac在线加盘操作引起)

发表于 2023 年 5 月 13 日 由 惜分飞

客户对asm进行扩容,执行udev_start命令之后,所有的vip全部漂移,业务全部中断
20230513203654

优先恢复业务,把所有vip漂移回来

[grid@rac3 ~]$  srvctl relocate vip -i rac1 -n rac1 -f -v
VIP was relocated successfully.
[grid@rac3 ~]$  srvctl relocate vip -i rac2 -n rac2 -f -v
VIP was relocated successfully.
[grid@rac3 ~]$  srvctl relocate vip -i rac3 -n rac3 -f -v
VIP was relocated successfully.
[grid@rac3 ~]$  srvctl relocate vip -i rac4 -n rac4 -f -v
VIP was relocated successfully.

vip恢复正常，业务也恢复正常
20230513203712

出现该问题的原因是由于udev_start命令引起网卡瞬间中断,从而使得vip发生漂移
20230513212316
查看ifcfg配置文件
20230513212440
引起该问题的原因是udev对网卡进行了操作,从而引起该问题,处理建议在对应的ifcfg文件中加上 HOTPLUG=”no” （pulbic,private和其他需要关注的网络）

处理异常事务,并且定位异常对象表

SQL> select owner,object_name,object_type from dba_objects where object_id=170692;

OWNER
--------------------------------------------------------------------------------
OBJECT_NAME
--------------------------------------------------------------------------------
OBJECT_TYPE

TABLE

rman检测逻辑坏块所属对象也是这个表（15个坏块均为该表）,对该表数据进行重建抛弃损坏数据,完成本次恢复
