Oracle 11g RAC环境下Private IP修改方法及异常处理

Oracle 11g RAC环境下Private IP修改方法及异常处理

Oracle 11g RAC环境下Private IP修改方法及异常处理
1、 修改方法

1. 确认全部节点CRS服务以启动
# olsnodes -s -n –i
host1 1 host1-vip Active
host2 2 host2-vip Active
2. 修改Private IP配置信息

若是以前只有一个私有网卡，则直接删除时会报错，如：PRIF-31: Failed to delete the
specified network interface because it is the last private interface.因此若是只是修改Private IP
而不用更改网卡时，能够参考如下操做命令：
oifcfg getif //查看Private IP配置
oifcfg setif -global en1/10.10.12.0:cluster_interconnect //添加en1新的Private IP
oifcfg delif -global en1/10.10.11.0 //删除en1旧的Private IP
oifcfg getif //查看Private IP配置

若是须要更改Private IP网卡时，能够参考以下命令：
oifcfg getif //查看Private IP配置
oifcfg setif -global en2/10.10.12.0:cluster_interconnect //增长新的en2 上的Private IP
oifcfg delif -global en1 //删除旧的en1上的Private IP
oifcfg getif //查看Private IP配

3. 关闭CRS服务（全部节点都要执行）：
参考命令：
#crsctl stop crs -f

4. 修改私有网络物理网卡IP地址和/etc/hosts文件（全部节点都要执行）：
参考命令：
# smit tcpip-> Minimum Configuration & Startup->en1
#vi /etc/hosts

5. 启动和查看CRS服务
参考命令：
#crsctl start crs
#crs_stat -t

2、异常处理
1. 问题描述
若是使用oifcfg setif命令修改Private IP配置信息时，subnet与实际配置的物理IP不致，
则重启CRS服务时会致使CRS没法启动，以下所示：
oifcfg setif命令配置：
oifcfg setif -global en1/10.10.12.0:cluster_interconnect //subnet为10.10.12.0
物理IP配置：
10.10.11.61/255.255.255.0 //subnet为10.10.11.0

2. 处理方法
可使用gpnptool命令处理以上问题。GPNPD（Greater Pittsburgh Nonprofit Partnership）
进程的主要的做用是在集群各个节点中同步GPnP profile文件，在Clusterware中，CSS、GPnP
等服务的启动都须要依赖于GPnP profile文件。而GPnP profile文件是一个xml文件，它存
储 的 位 置 是 在 ： $GRID_HOME/gpnp//profile/peer/profile.xml ，
$GRID_HOME/gpnp/profile/peer/profile.xml（全局备份，最原始的配置信息）。GPnPD进程写
的trace文件会存放在$GRID_HOME/log//gpnpd/gpnpd.log。
有几个重要的信息存储在GPnP profile文件:
? 网络接口和IP地址(公网和私网)
? ASM diskstring和spfile信息
GPnP profile保存的是RAC的配置信息，包括集群名称、网络类型信息（public/private）、
ASM和CSS的存储信息、安全的数字签名，以及ASM实例的SPFILE文件位置。当集群配置
发生变化时，全部节点的该文件会被自动更新。在安装、系统引导或者当使用标准的集群工
具更新期间，这些活动包括：oifcfg 改变网络信息、crsctl 改变css设备、ASM额外的存储
等，会经过gpdpd进程复制GPnP profile到全部的其余节点。
当集群启动的时候，Cluster Synchronization Services (CSS)将扫描全部的ASM disks，它利
用的是GPnP profile文件中的ASM discovery string。以下所示:

egistry.253.790450611"/>
这里能够看到spfile文件是存放在ASM卷组+DATA中的。可是有一个须要注意到事情是
咱们启动ASM的时候，须要spfile文件，Oracle从GPnP profile中知道spfile的路径，而后
它就会从底层磁盘中直接读取spfile标识，启动asm实例。
若是GPnP出现问题，可使用cluvfy comp gpnp组件验证命令检查在集群中全部节点
网格即插即用的完整性：cluvfy comp gpnp [-n node_list] [-verbose]
最后，注意Oracle不支持手动修改profile.xml文件，直接对它的修改可能致使没法修复
的问题，最终致使在全部节点重建Clusterware。

2.1 以排他模式和不启动crsd进程的方式启动crs
# crsctl start crs -excl –nocrs

2.2 备份crs配置信息
#mkdir /u01/gpnp

备注：备份的profile.xml文件配置信息与‘gpnptool get’显示配置信息彻底相同，同时也
与$ORACLE_HOME /gpnp//profiles/peer下的profile.xml文件信息相同。

2.3 修改备份的CRS配置信息
2.3.1 备份配置文件：
# cp /u01/gpnp/profile.xml /u01/gpnp/p.xml

2.3.2 获取当前的序列号（每次修改并写回crs中会有一个序列号做为标识）：
# gpnptool getpval -p=/u01/gpnp/p.xml -prf_sq -o-
22

2.3.3 获取共有网络和私有网络标识id （与实际网卡名称不一致，能够在配置文件中找到）：
# gpnptool getpval -p=/u01/gpnp/p.xml -net -o-
net1 net3

2.3.4 修改配置文件中的序列号（原序列号值加1）和私网的实际网段（subnet）信息：
# gpnptool edit -p=/u01/gpnp/p.xml -o=/u01/gpnp/p.xml -ovr -prf_sq=23 -net3:net_ip=10.10.11.0
Resulting profile written to "/u01/gpnp/p.xml".
Success.
修改网卡名称
#gpnptool edit -p=/home/app/11.2.0.3/grid/gpnp/profiles/peer/profile.xml -o=/home/app/11.2.0.3/grid/gpnp/profiles/peer/profile.xml -ovr -prf_sq=5 net3:net_ada=em3

2.3.7 用私钥从新标识配置文件：
# gpnptool sign -p=/u01/gpnp/p.xml -o=/u01/gpnp/p.xml -ovr -w=cw-fs:peer
Resulting profile written to "/u01/gpnp/p.xml".
