标题:Oracle 12.1 RAC 系列-安装新主机,识别老存储和恢复数据库
作者:Lunar©版权所有[文章允许转载,但必须以链接方式注明源地址,否则追究法律责任.]
在11.2中模拟主机损坏,使用重新安装新主机识别老存储并恢复数据库。
11.2 RAC 系列-安装新主机,识别老存储-1-识别ASM磁盘
11.2 RAC 系列-安装新主机,识别老存储-2-准备识别数据库
11.2 RAC 系列-安装新主机,识别老存储-3-配置老存储的数据库
这里的测试也同样是模拟主机损坏,安装新主机识别老存储来恢复数据库,不同之处在于,这里假设老存储的ocr和vf是保存在单独的crsdg的,客户没有新的磁盘来创建新的crsdg,因此,我们需要将最前面的3块盘(除去sda后,是sdb~sdd)使用dd清除其前面50M的数据,然后用这3块盘组成后续安装GI时的CRSDG。
别的过程几乎都一样,添加数据库资源的时候,注意一下12.1跟11.2的命令不同,尽管12.1中如果使用11.2的添加数据库的命令也可以执行,并且没有报错信息(貌似兼容),但后续使用时可能会有问题,比如在ocr中识别的dbunique的信息是不正确的。
.
具体步骤如下(因为先在12.1中测试,然后才在112.测试,因此这里的测试记录了发现的一些问题和处理方法,而11.2中模拟主机损坏,直接使用了这里的经验,因此没有任何报错信息):
1,安装12.1.0.2的GI软件,如果需要也apply最新的PSU,然后查看磁盘和磁盘组:

创建ASM的spfile

查找spfile:
SYS@+ASM1>SELECT f.group_number, f.file_number, a.name name, f.type type 2 FROM v$asm_file f, v$asm_alias a 3 WHERE f.group_number=a.group_number and f.file_number=a.file_number 4 and f.type='PARAMETERFILE' 5 ORDER BY 1, 2; GROUP_NUMBER FILE_NUMBER NAME TYPE ---------------- ---------------- ------------------------------------------------------- ------------------------- 1 268 spfile.268.903782013 PARAMETERFILE 2 273 spfile.273.892298577 PARAMETERFILE Elapsed: 00:00:00.16 SYS@+ASM1>
这里看到有两个spfile,哪一个是我们需要的呢?
或者如果这个存储上有多个数据库时,怎么确定哪个数据库使用哪个spfle?
我们知道ASM内部是使用OMF管理数据文件的,因此,它的命名规则是:
因此,根据dbuniquename我们就可以确定哪个数据库使用哪个spfile。
+group/DB_UNIQUE_NAME/file_type/file_type_tag.file#.incarnation#
文件类型是datafile, controlfile, onlinelog等等
ASMCMD> ls -l Type Redund Striped Time Sys Name PARAMETERFILE UNPROT COARSE DEC 25 10:00:00 Y spfile.273.892298577 ASMCMD> pwd +datadg2/lunar/PARAMETERFILE ASMCMD>
我们将spifle从ASM中复制到文件系统,然后查看其中信息是否正确:
ASMCMD> cp spfile.273.892298577 /tmp/spfile.273.892298577 copying +datadg2/lunar/PARAMETERFILE/spfile.273.892298577 -> /tmp/spfile.273.892298577 ASMCMD> ls -l Type Redund Striped Time Sys Name PARAMETERFILE UNPROT COARSE FEB 14 20:00:00 Y spfile.273.892298577 ASMCMD>
查看spfile

这时,启动是数据库会报错:

根据报错信息,我们知道,是因为oracle没有访问asm磁盘组的权限造成的,因此需要修改oracle权限:

再次mount数据库,依然报错:

将数据库注册到ocr中:
在12.1中如果沿用11.2的配置数据库命令,那么数据库可以启动,但是可以发现配置信息是有问题的:
例如,“Database name: lunarrac”这里显示lunarrac是我的主机名,而数据库名是lunar,因此使用112.的命令注册数据库到ocr会有其他未知问题
建议,在不同版本,根据不同版本的命令进行注册。

在挂完老存储后,还需要检查口令文件,如果有必要,需要重新给sys和system授予sysdba,sysoper权限,以便使用操作系统认证方式登录数据库。
