Oracle RAC on Veritas DBE/AC(Step by Step)
在Solaris中安装Veritas DBAC for Oracle RAC 一、 安装Solaris 9 8/03版本，由于该版本是Solaris操作系统的最新版，所以不需要在安装补丁程序。 二、 使用Sun公司发布的补丁盘，安装SUNWsan软件包和补丁包 三、 为要安装Oracle RAC的Sun V880设置好网络 主机A： 机器名：rac1 网卡 eri0：192.0.0.101/255.255.255.0 用于做心跳网卡2 网卡 ge0：192.0.1.101/255.255.255.0 用于做心跳网卡1 网卡 ce0：172.39.199.101/255.255.255.0 用于做对外服务网卡 主机A具体配置文件如下： l /etc/hosts文件的内容： # # Internet host table # 127.0.0.1 localhost 192.168.0.101 rac1 loghost a.b 192.168.0.102 rac2 192.168.1.101 rac1-ge0 172.39.199.101 rac1-ce0 l /etc/netmasks文件的内容 # # The netmasks file associates Internet Protocol (IP) address # masks with IP network numbers. # # network-number netmask # # The term network-number refers to a number obtained from the Internet Network # Information Center.

Display help about menu ?? Display help about the menuing system q Exit from menus Select an operation to perform: 1 Add or initialize disks Menu: VolumeManager/Disk/AddDisks Use this operation to add one or more disks to a disk group. You can add the selected disks to an existing disk group or to a new disk group that will be created as a part of the operation. The selected disks may also be added to a disk group as spares. Or they may be added as nohotuses to be excluded from hot-relocation use. The selected disks may also be initialized without adding them to a disk group leaving the disks available for use as replacement disks. More than one disk or pattern may be entered at the prompt. Here are some disk selection examples: all: all disks c3 c4t2: all disks on both controller 3 and controller 4, target 2 c3t4d2: a single disk (in the c#t#d# naming scheme) xyz_0 : a single disk (in the enclosure based naming scheme) xyz_ : all disks on the enclosure whose name is xyz Select disk devices to add: [,all,list,q,?] c2 /* 需要在rac1和rac2上进行初始化 */ 十四、 进行SCSI-3 PR（I/O Fencing）测试 确定不同计算机上的两块硬盘是不是同一块硬盘的方法： root@rac1 # vxfenadm -i /dev/rdsk/c2t0d0s2 Vendor id : IBM Product id : 1742-900 Revision : 0520 Serial Number : }? ?? root@rac1 # rlogin rac2 Last login: Mon Nov 17 10:03:57 from 172.39.199.112 Sun Microsystems Inc.

/sbin/gabconfig -a GAB Port Memberships =============================================================== Port a gen 4a1c0001 membership 01 Port b gen g8ty0002 membership 01 Port d gen 40100001 membership 01 Port f gen f1990002 membership 01 Port h gen d8850002 membership 01 Port o gen f1100002 membership 01 Port q gen 28d10002 membership 01 Port v gen 1fc60002 membership 01 Port w gen 15ba0002 membership 01 如果有Port b gen g8ty0002 membership 01这一行信息显示，则表示I/O Fensing的功能已经启动。 十六、 为SRVM创建共享卷组和卷，以下的命令，在rac1上执行就可以了： vxdg -s init orasrv_dg c2t0d4 vxassist -g orasrv_dg make srvm_vol 300M vxedit set diskdetpolicy=local orasrv_dg vxdg -g orasrv_dg set activation=sw rsh -l root rac2 vxdg -g orasrv_dg set activation=sw 十七、 在rac1和rac2上创建dba组和oracle用户：oracle用户的主组是dba；主目录是/opt/oracle；shell是Bourne Shell，其环境文件如下 stty istrip PATH=/usr/bin:/usr/ucb:/etc:. export PATH ORACLE_BASE=/opt/oracle export ORACLE_BASE ORACLE_OWNER=oracle export ORACLE_OWNER ORACLE_HOME=/opt/oracle/VRT export ORACLE_HOME ORACLE_TERM=xsun5 export ORACLE_TERM ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data export ORA_NLS33 LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME/jdbc/lib:usr/bin: /lib:/usr/lib:/usr/openwin/lib export LD_LIBRARY_PATH PATH=$PATH:/usr/bin:/usr/ucb:/etc:$ORACLE_HOME/bin:/opt/bin:/usr/ccs/bin: export PATH ORACLE_DOC=$ORACLE_HOME/DOC export ORACLE_DOC DBCA_RAW_CONFIG=/opt/oracle/dbfile export DBCA_RAW_CONFIG 在主目录下创建目录/opt/oracle/VRT # mkdir /opt/oracle/VRT 在主目录下创建文件/opt/oracle/.rhosts，其内容为： rac1 rac2 十八、 在rac1和rac2上修改文件/etc/system，加入如下内容： set shmsys:shminfo_shmmax=4294967296 set shmsys:shminfo_shmmin=1 set shmsys:shminfo_shmmni=100 set shmsys:shminfo_shmseg=10 set semsys:seminfo_semmni=100 set semsys:seminfo_semmns=1024 set semsys:seminfo_semmsl=256 set semsys:seminfo_semopm=100 set semsys:seminfo_semvmx=32767 十九、 重新启动计算机rac1和rac2 在rac2上 # halt OK 在rac1上 # reboot 等rac1启动可以登录后，再启动rac2 OK boot 二十、 在rac1和rac2上执行如下步骤： # cd /opt/ORCLcluster/lib/9iR2 # cp libskgxn2_64.so ../libskgxn2.so /* 64位数据库版本，如果是64位数据库版本执行cp libskgxn2_32.so ../libskgxn2.so */ 二十一、 运行oracle 9iR2的runInstaller程序，开始安装Oracle RAC，需要注意以下几点： 1、 需要选择所有的集群节点 2、 根据提示输入SRVM共享卷/dev/vx/rdsk/orasrv_dg/srvm_vol 3、 安装时需要选择Software Only(只安装oracle软件) 二十二、 以oracle用户的身份在rac1和rac2上运行如下命令： $ cp /opt/ORCLcluster/lib/9iR2/libskgxp92_64.so $ORACLE_HOME/lib/libskgxp9.so $ cd $ORACLE_HOME/lib $ mv libodm9.so libodm9.so.old $ ln -s /usr/lib/sparcv9/libodm.so libodm9.so 二十三、 在目录/opt/oracle下创建文件dbfile，内容为 system=/dev/vx/rdsk/oradata_dg/system1_vol spfile=/dev/vx/rdsk/oradata_dg/spfile1_vol users=/dev/vx/rdsk/oradata_dg/user1_vol temp=/dev/vx/rdsk/oradata_dg/temp1_vol undotbs1=/dev/vx/rdsk/oradata_dg/undotbs1_vol undotbs2=/dev/vx/rdsk/oradata_dg/undotbs2_vol example=/dev/vx/rdsk/oradata_dg/example1_vol cwmlite=/dev/vx/rdsk/oradata_dg/cwmlite1_vol indx=/dev/vx/rdsk/oradata_dg/indx1_vol tools=/dev/vx/rdsk/oradata_dg/tools1_vol drsys=/dev/vx/rdsk/oradata_dg/drsys1_vol control1=/dev/vx/rdsk/oradata_dg/control1_vol control2=/dev/vx/rdsk/oradata_dg/control2_vol redo1_1=/dev/vx/rdsk/oradata_dg/redo1_1_vol redo1_2=/dev/vx/rdsk/oradata_dg/redo1_2_vol redo2_1=/dev/vx/rdsk/oradata_dg/redo2_1_vol redo2_2=/dev/vx/rdsk/oradata_dg/redo2_2_vol odm01=/dev/vx/rdsk/oradata_dg/odm1_vol xml01=/dev/vx/rdsk/oradata_dg/xml1_vol 二十四、 在/opt/oracle/.profile文件中加入如下两行，配置环境变量 DBCA_RAW_CONFIG=/opt/oracle/dbfile export DBCA_RAW_CONFIG 二十五、 用oracle的身份登录，运行dbca图形工具创建数据库 $ dbca 这一步需要注意的是： 1、 选中创建集群数据库； 2、 注意选择oracle数据库的字符集 二十六、 修改/opt/oracle/VRT/network/admin/tnsnames.ora文件,修改后的文件内容为: # TNSNAMES.ORA Network Configuration File: /opt/oracle/VRT/network/admin/tnsname s.ora # Generated by Oracle configuration tools. LISTENERS_ORADB = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = rac2)(PORT = 1521)) ) INST1_HTTP = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1521)) ) (CONNECT_DATA = (SERVER = SHARED) (SERVICE_NAME = MODOSE) (PRESENTATION = ) ) ) LISTENER_ORADB2 = (ADDRESS = (PROTOCOL = TCP)(HOST = rac2)(PORT = 1521)) ORADB2 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = rac2)(PORT = 1521)) (CONNECT_DATA = (SERVICE_NAME = oradb) (INSTANCE_NAME = oradb2) ) ) LISTENER_ORADB1 = (ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1521)) ORADB1 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1521)) (CONNECT_DATA = (SERVICE_NAME = oradb) (INSTANCE_NAME = oradb1) ) ) ORADB = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = rac2)(PORT = 1521)) (LOAD_BALANCE = yes) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = oradb) (FAILOVER_MODE= (TYPE=select) (METHOD=basic) ) ) ) 二十七、 在rac1上的文件/opt/oracle/.profile文件加入如下: ORACLE_SID=oradb1 export ORACLE_SID 二十八、 在rac1上的文件/opt/oracle/.profile文件加入如下: ORACLE_SID=oradb2 export ORACLE_SID
