bay——Oracle RAC环境下ASM磁盘组扩容.docx

 

生产环境注意调整以下参数
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+ 1.节点间滚动添加UDEV磁盘
+ 2.ASM 内存大小
+ 3.POWER_LIMIT别弄太大
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
 
实验环境
--系统环境:Centos 6.10
--数据库:Oracle 11g RAC
--磁盘绑定:udev
 
实验目的
--存储空间不足,需要给磁盘组DATA加一块磁盘
 
 
准备工作
    1.检查各个节点database、asm及grid日志是否有错误信息
 
 
    2.检查各个节点服务状态(切换到grid用户)
      --列出数据库名
        [grid@node2 ~]$ srvctl config database 
        RacNode
        [grid@node2 ~]$ 
        
      --实例状态
        [grid@node2 ~]$ srvctl status database -d  RacNode 
        Instance RacNode1 is running on node node1
        Instance RacNode2 is running on node node2
        [grid@node2 ~]$  
        
      --集群状态:
        [grid@node2 ~]$ crsctl check cluster -all 
        **************************************************************
        node1:
        CRS-4537: Cluster Ready Services is online
        CRS-4529: Cluster Synchronization Services is online
        CRS-4533: Event Manager is online
        **************************************************************
        node2:
        CRS-4537: Cluster Ready Services is online
        CRS-4529: Cluster Synchronization Services is online
        CRS-4533: Event Manager is online
        **************************************************************
        [grid@node2 ~]$  
        
      --集群资源状态
        [grid@node2 ~]$ crsctl status res -t   
 
    3.ASM磁盘组及磁盘检查
        [grid@node1 ~]$ export ORACLE_SID=+ASM1
        [grid@node1 ~]$ sqlplus /nolog
        SQL> conn /as sysasm
        
        --显示使用ASM磁盘组的数据库

        [root@node2 ~]# 
        
 
进入实验阶段        
    1.停止对应数据库的业务
    2.检查数据库会话及停止监听
      --检查各个节点监听状态
        [grid@node1 ~]$ srvctl status listener -n node1
        Listener LISTENER is enabled on node(s): node1
        Listener LISTENER is running on node(s): node1
        [grid@node1 ~]$ srvctl status listener -n node2
        Listener LISTENER is enabled on node(s): node2
        Listener LISTENER is running on node(s): node2
        [grid@node1 ~]$ 
      
      --禁止监听自启动
        [grid@node1 ~]$ srvctl disable listener -n node1
        [grid@node1 ~]$ srvctl disable listener -n node2  
            
      --停止监听
        [grid@node1 ~]$ srvctl stop listener -n node1
        [grid@node1 ~]$ srvctl stop listener -n node2
            
      --查看停止及关闭自启后的监听状态    
        [grid@node1 ~]$ srvctl status listener -n node1
        Listener LISTENER is disabled on node(s): node1
        Listener LISTENER is not running on node(s): node1
        [grid@node1 ~]$ srvctl status listener -n node2
        Listener LISTENER is disabled on node(s): node2
        Listener LISTENER is not running on node(s): node2
        [grid@node1 ~]$        
            
    3.关闭数据库
      --检查数据库配置
        [grid@node1 ~]$ srvctl config database -d RacNode
        Database unique name: RacNode
        Database name: RacNode
        Oracle home: /u01/app/oracle/11.2.0/dbhome_1
        Oracle user: oracle
        Spfile: +DATA/RacNode/spfileRacNode.ora
        Domain: 
        Start options: open
        Stop options: immediate
        Database role: PRIMARY
        Management policy: AUTOMATIC
        Server pools: RacNode
        Database instances: RacNode1,RacNode2
        Disk Groups: DATA
        Mount point paths: 
        Services: 
        Type: RAC
        Database is administrator managed
        [grid@node1 ~]$ 
            
      --禁止数据库自启动(需切换root用户)
        [root@node2 ~]# cd /u01/app/11.2.0/grid/bin
        [root@node2 bin]# ./srvctl disable database -d RacNode
        [root@node2 bin]#  
            
      --关闭数据库
        [grid@node1 ~]$ srvctl stop database -d  RacNode
        [grid@node1 ~]$       
            
      --检查关闭后数据库状态
        [grid@node1 ~]$ srvctl status database -d  RacNode 
        Instance RacNode1 is not running on node node1
        Instance RacNode2 is not running on node node2
        [grid@node1 ~]$  
            
    4.关闭集群软件
      --查看各个节点集群是否为自启动        
        [root@node1 bin]# ./crsctl config has
        CRS-4622: Oracle High Availability Services autostart is enabled.
        [root@node1 bin]#    
        [root@node2 bin]# ./crsctl config has
        CRS-4622: Oracle High Availability Services autostart is enabled.    
                
      --禁止各个节点的自启动
        [root@node1 bin]# ./crsctl disable has
        CRS-4621: Oracle High Availability Services autostart is disabled.
        [root@node1 bin]#
        [root@node2 bin]# ./crsctl disable has
        CRS-4621: Oracle High Availability Services autostart is disabled.
        [root@node2 bin]# 
 
      --查看各个节点禁止自启动是否生效
        [root@node1 bin]# ./crsctl config has
        CRS-4621: Oracle High Availability Services autostart is disabled.
        [root@node1 bin]# 
        [root@node2 bin]# ./crsctl config has
        CRS-4621: Oracle High Availability Services autostart is disabled.
        [root@node2 bin]# 
 
      --停止各个节点集群
        [root@node1 bin]# ./crsctl stop has
        [root@node2 bin]# ./crsctl stop has
 
    5.系统层面添加磁盘(存储工程师协助完成)
 
 
    6.各个节点使用UDEV添加磁盘
      --确定盘符
        fdisk -l
        /dev/sdk
        /dev/sdl
        /dev/sdm
        /dev/sdn
 
      --获取绑定规则
        for i in k l m n
        do  
        echo "KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="`/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`", NAME="asm-disk$i", OWNER="grid", GROUP="asmadmin", MODE="0660""

      --各个节点将规则添加到rule文件99-oracle-asmdevices.rules
      
      --重启udev
        [root@node1 rules.d]# start_udev
        [root@node2 rules.d]# start_udev
 
 
      --确认添加磁盘,确保各个节点可以识别到磁盘且一致
        [root@node2 rules.d]# ll /dev/asm-*

        [root@node2 rules.d]#
 
    7.启动集群
        [root@node1 bin]# ./crsctl start has
        CRS-4123: Oracle High Availability Services has been started.
        [root@node2 bin]# ./crsctl start has
        CRS-4123: Oracle High Availability Services has been started.
        [root@node2 bin]# 
 
      --检查集群的各个组件是否启动正常
        [grid@node2 ~]$ crsctl status res -t
        
        此时,监听和数据库服务是停掉的
        
    8.ASM扩容
