验证11gR2 RAC中ASM实例通过gpnp profile获得spfile信息来启动AS

Jun 07, 2016 pm 02:50 PM
asm pr rac 实例 通过 验证

主要为了验证11gR2 RAC中ASM实例通过gpnp profile获得spfile信息来启动ASM实例,同时验证了gpnp profile的修改等内容;结论与实验如下: 验证结论: 1./u01/app/11.2.0/grid/gpnp/profiles/peer下的cat profile.xml内容是旧的,使用spset/spmove时均未被更新

主要为了验证11gR2 RAC中ASM实例通过gpnp profile获得spfile信息来启动ASM实例,同时验证了gpnp profile的修改等内容;结论与实验如下:
验证结论:
1./u01/app/11.2.0/grid/gpnp/profiles/peer下的cat profile.xml内容是旧的,使用spset/spmove时均未被更新,一些文档说这个 profile.xml是全局的。
gpnp使用的是/u01/app/11.2.0/grid/gpnp/rac1/profiles/peer下的cat profile.xml内容,即$ORACLE_HOME/gpnp/[HOSTNAME]/profiles/peer/

2.修改是通过ASMCMD的spset/spmove命令来实现的修改gpnp profile,
通过gpnptool edit -p=profile.xml -asm_spf="+DATA1/rac-cluster/asmparameterfile/registry.253.857644239" 这种命令,显示修改成功,但是未发现profile.xml中信息变化,重新启动OS/HAS等方式均未发现使用新的修改,求告知原因。

3.gpnp profile不能手动修改,手动编辑会导致文件损坏,查看gpnpd.log可以发现校验文件出错的信息,但是可以从缓存中查找gpnp profile并启动。

实验1:验证ASM实例启动时依赖gpnp profile中的SPFILE信息
1.修改gpnp profile中关于SPFILE的信息并验证修改成功
ASMCMD> spset +DATA1/rac-cluster/asmparameterfile/spfile.ora
ASMCMD> spget
+DATA1/rac-cluster/asmparameterfile/spfile.ora   
查看/u01/app/11.2.0/grid/gpnp/profiles/peer下的cat profile.xml内容,可以发现未修改,仍是ProfileSequence="4" 。
查看/u01/app/11.2.0/grid/gpnp/rac1/profiles/peer下的cat profile.xml内容,发现已经修改,ProfileSequence="8" ,SPFile="+DATA1/rac-cluster/asmparameterfile/spfile.ora。
此时/u01/app/11.2.0/grid/gpnp/rac1/profiles/peer下还出现了一个pending.xml文件,里面的内容是最新的信息。
此时使用 kfed read /dev/asm-diskb|grep spfile可以发现SPFILE的信息未变化。
[grid@rac1 peer]$ kfed read /dev/asm-diskb|grep spfile
kfdhdb.spfile:                       58 ; 0x0f4: 0x0000003a

此时启动HAS,查看ASM的ALERT LOG中使用的ASM SPFILE信息,可以发现使用了新的GPnP-Profile中的配置,出现如下报错:
ERROR: SPFile in diskgroup DATA1 does not match the specified spfile +DATA1/rac-cluster/asmparameterfile/spfile.ora

此时使用默认的参数启动ASM实例,然后磁盘组做为资源--ora.DATA1.dg也被AGENT发出的MOUNT命令成功挂载,


这里根据实验结果来推测一种可能-->如何找到ASM SPFile:(如下步骤1、2谁先谁后应该都可以,我是根据gpnp profile中DiscoveryString在前觉得应该是先进行步骤1)
      1.gpnp profile中DiscoveryString字段找到相应的磁盘,读取磁盘头获取SPFILE信息,如KFED读到的信息:[grid@rac1 peer]$ kfed read /dev/asm-diskb|grep spfile
      kfdhdb.spfile:                       58 ; 0x0f4: 0x0000003a
      2.从磁盘头获取了SPFILE信息并去读取--?后,再与gpnp profile中SPFile=指定的文件信息做对比,如果一致,则使用。如果不一致,则去$ORACLE_HOME/dbs下查找spfile+ASM1.ora这种查找路径,如果仍找不到,再使用默认参数启动。
      3.问题点在于DiscoveryString="/dev/asm*" SPFile="部分,在实验中可以发现,将SPFile=改为一个不存在的文件;此时通过kfed读取磁盘头可以找到正确的SPFILE信息,但是并未被使用;因此有此推断。


实验2:ASMCMD> spmove REGISTRY.253.857644239 +DATA2/spfileasm.ora

此命令会将ASM SPFILE文件移到到+DATA2/spfileasm.ora --别名;原来ASM SPFILE在+DATA1,只能移到不同的磁盘组;
spmove 移动后,会自动更新gpnp profile中信息;同时使用kfed 读取磁盘头信息,也同步进行了更新。

如下是实验过程的简要步骤与具体实验信息:
1.查看gpnp profile信息
2.查看ASM的ALERT LOG中使用的ASM SPFILE信息

实验1:
1.修改gpnp profile中关于SPFILE的信息并验证修改成功
2.启动HAS,查看ASM的ALERT LOG中使用的ASM SPFILE信息
实验2:
1.spmove 验证kfed 中读到的信息是否变化及gpnp profile中信息也被修改
实验3:设置为正确的asm spfile信息,经过crsctl stop/start has 和重启OS,查看GPNP PROFILE所在目录中还存在pending.xml
但是在实验2中,spmove后不存在pending.xml了。
