Oracle 11g RAC環境下Private IP修改方法及異常處理


Oracle 11g RAC環境下Private IP修改方法及異常處理

Oracle 11g RAC環境下Private IP修改方法及異常處理
一、 修改方法

1. 確認所有節點CRS服務以啟動
# olsnodes -s -n –i
host1 1 host1-vip Active
host2 2 host2-vip Active
2. 修改Private IP配置信息

如果之前只有一個私有網卡,則直接刪除時會報錯,如:PRIF-31: Failed to delete the
specified network interface because it is the last private interface.所以如果只是修改Private IP
而不用更改網卡時,可以參考以下操作命令:
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 //刪除en1舊的Private IP
oifcfg getif //查看Private IP配置

如果需要更改Private IP網卡時,可以參考如下命令:
oifcfg getif //查看Private IP配置
oifcfg setif -global en2/10.10.12.0:cluster_interconnect //增加新的en2 上的Private IP
oifcfg delif -global en1 //刪除舊的en1上的Private IP
oifcfg getif //查看Private IP配

3. 關閉CRS服務(所有節點都要執行):
參考命令:
#crsctl stop crs -f

4. 修改私有網絡物理網卡IP地址和/etc/hosts文件(所有節點都要執行):
參考命令:
# smit tcpip-> Minimum Configuration & Startup->en1
#vi /etc/hosts

5. 啟動和查看CRS服務
參考命令:
#crsctl start crs
#crs_stat -t

二、異常處理
1. 問題描述
如果使用oifcfg setif命令修改Private IP配置信息時,subnet與實際配置的物理IP不致,
則重啟CRS服務時會導致CRS無法啟動,如下所示:
oifcfg setif命令配置:
oifcfg setif -global en1/10.10.12.0:cluster_interconnect //subnet為10.10.12.0
物理IP配置:
10.10.11.61/255.255.255.0 //subnet為10.10.11.0

2. 處理方法
可以使用gpnptool命令處理以上問題。GPNPD(Greater Pittsburgh Nonprofit Partnership)
進程的主要的作用是在集群各個節點中同步GPnP profile文件,在Clusterware中,CSS、GPnP
等服務的啟動都需要依賴於GPnP profile文件。而GPnP profile文件是一個xml文件,它存
儲 的 位 置 是 在 : $GRID_HOME/gpnp//profile/peer/profile.xml ,
$GRID_HOME/gpnp/profile/peer/profile.xml(全局備份,最原始的配置信息)。GPnPD進程寫
的trace文件會存放在$GRID_HOME/log//gpnpd/gpnpd.log。
有幾個重要的信息存儲在GPnP profile文件:
? 網絡接口和IP地址(公網和私網)
? ASM diskstring和spfile信息
GPnP profile保存的是RAC的配置信息,包括集群名稱、網絡類型信息(public/private)、
ASM和CSS的存儲信息、安全的數字簽名,以及ASM實例的SPFILE文件位置。當集群配置
發生變化時,所有節點的該文件會被自動更新。在安裝、系統引導或者當使用標准的集群工
具更新期間,這些活動包括:oifcfg 改變網絡信息、crsctl 改變css設備、ASM額外的存儲
等,會通過gpdpd進程復制GPnP profile到所有的其他節點。
當集群啟動的時候,Cluster Synchronization Services (CSS)將掃描所有的ASM disks,它利
用的是GPnP profile文件中的ASM discovery string。如下所示:

egistry.253.790450611"/>
這里可以看到spfile文件是存放在ASM卷組+DATA中的。但是有一個需要注意到事情是
我們啟動ASM的時候,需要spfile文件,Oracle從GPnP profile中知道spfile的路徑,然后
它就會從底層磁盤中直接讀取spfile標識,啟動asm實例。
如果GPnP出現問題,可以使用cluvfy comp gpnp組件驗證命令檢查在集群中所有節點
網格即插即用的完整性:cluvfy comp gpnp [-n node_list] [-verbose]
最后,注意Oracle不支持手動修改profile.xml文件,直接對它的修改可能導致無法修復
的問題,最終導致在所有節點重建Clusterware。

2.1 以排他模式和不啟動crsd進程的方式啟動crs
# crsctl start crs -excl –nocrs


2.2 備份crs配置信息

備注:備份的profile.xml文件配置信息與‘gpnptool get’顯示配置信息完全相同,同時也
與$ORACLE_HOME /gpnp//profiles/peer下的profile.xml文件信息相同。

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

2.3.2 獲取當前的序列號(每次修改並寫回crs中會有一個序列號作為標識):
# gpnptool getpval -p=/u01/gpnp/p.xml -prf_sq -o-
22

2.3.3 獲取共有網絡和私有網絡標識id (與實際網卡名稱不一致,可以在配置文件中找到):
# gpnptool getpval -p=/u01/gpnp/p.xml -net -o-
net1 net3

2.3.4 修改配置文件中的序列號(原序列號值加1)和私網的實際網段(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.
修改網卡名稱
#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 用私鑰重新標識配置文件:
# 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".
