ASM DISK Group加载ORA-15183错误一例

进入Oracle 11gR2，ASM（Automatic Storage Management）从Database组件中剥离出来，作为独立组件Component进入Grid管理范畴。

进入Oracle 11gR2，ASM（Automatic Storage Management）从Database组件中剥离出来，作为独立组件Component进入Grid管理范畴。

本篇主要介绍笔者遇到的一个数据库启动加载过程中出现的问题。同官方MOS推荐的策略相比，有一些不同之处。记录下来，留待需要的朋友待查使用。

1、问题说明

笔者环境是Oracle 单实例+Grid Infrastructure，版本号为11.2.0.4。由于安全原因，从MOS上下载了最新的安全补丁和升级补丁。升级之后的版本为11.2.0.4.6。

但是，在升级最后步骤——执行SQL脚本环节，出现了一些问题。

ORA-00205: error in identifying control file, check alert log for more info

从提示信息角度看，Oracle在经历启动nomount阶段之后，在定位control file的过程中出现了问题。

老实说，虽然是测试环境，但是笔者还是比较惊慌的。于是尝试使用srvctl集群件启动策略。

[grid@NCR-Standby-Asm ~]$ srvctl start database -d sicsstb

PRCC-1014 : sicsstb was already running

PRCR-1004 : Resource ora.sicsstb.db is already running

PRCR-1079 : Failed to start resource ora.sicsstb.db

CRS-5702: Resource 'ora.sicsstb.db' is already running on 'ncr-standby-asm'

2、问题分析

首先确认系统是否可以使用srvctl启动，判断一下GI上面各种资源resource状态。

[grid@NCR-Standby-Asm ~]$ srvctl stop database -d sicsstb

[grid@NCR-Standby-Asm ~]$ srvctl status asm

ASM is running on ncr-standby-asm

[grid@NCR-Standby-Asm ~]$ crsctl stat res -t -init

笔者猜测，这个故障和ASM相关。按照逐步抽丝剥茧的思路，先从数据库日志入手（找到失败启动的那次动作）。

从提示信息看，Oracle在mount阶段时候，利用spfile中指定的control file位置去访问+DATA和+RECO磁盘组，，但是两个磁盘组没有mount，所以才开始报错。

参数中，control file以镜像冗余方式存在在ASM Diskgroup中。
