rpm -Uvh unixODBC-devel-2.*

rpm -Uvh sysstat-7.*

2.给linux系统配置ntp，ftp

3.配置linux网络：

1)在两个节点上编辑/etc/hosts文件：

127.0.0.1 localhost.localdomain localhost

#used by ntp serviceto synchronize time

66.187.233.4 clock.redhat.com

#local network forRAC

192.168.0.131 ora10racn1 ora10racn1.ccz.com

192.168.0.132 ora10racn2 ora10racn2.ccz.com

192.168.0.151 ora10racn1-vip

192.168.0.152 ora10racn2-vip

192.168.2.131 ora10racn1-str

192.168.2.132 ora10racn2-str

10.10.0.131 ora10racn1-priv

10.10.0.132 ora10racn2-priv

192.168.0.110 openfiler

192.168.2.110 openfiler-str

2)确保节点的主机名称不在loopback中出现：

127.0.0.1 localhost.localdomain localhost

3)修改/etc/sysctl.conf中的网络设置：

#+---------------------------------------------------------+

# | Default settingin bytes of the socket "receive" buffer |

# | which may be setby using the SO_RCVBUF socket option. |

net.core.rmem_default=1048576

# | Maximum settingin bytes of the socket "receive" buffer |

net.core.rmem_max=1048576

# | Default settingin bytes of the socket "send" buffer |

# | which may be setby using the SO_SNDBUF socket option. |

net.core.wmem_default=262144

# | Maximum settingin bytes of the socket "send" buffer |

net.core.wmem_max=262144

4)关闭所有节点上的UDP ICMP的rejection

[root@ora10racn1Server]# /etc/rc.d/init.d/iptables status

Firewall is stopped.

如果是running状态需要用以下命令关闭：

[root@ora10racn1Server]# /etc/rc.d/init.d/iptables stop

在各个运行级别上关闭iptables

[root@ora10racn1Server]# chkconfig --list|grep iptables

iptables 0:off1:off 2:on 3:on4:on 5:on 6:off

[root@ora10racn1Server]# chkconfig iptables off

iptables 0:off1:off 2:off 3:off4:off 5:off 6:off

4.创建oracle用户并确认nobody帐号的存在:

# groupadd -g 501 oinstall

# groupadd -g 502 dba

# groupadd -g 503 oper

# useradd -m -u 501 -g oinstall-G dba,oper -d /home/oracle -s /bin/bash oracle

# id oracle

uid=501(oracle) gid=501(oinstall)groups=501(oinstall),502(dba),503(oper)

# passwd oracle

Changing password for useroracle.

New UNIX password: xxxxxxxxxxx

Retype new UNIX password:xxxxxxxxxxx

passwd: all authentication tokensupdated successfully.

修改oracle帐号的.bash_profile

export JAVA_HOME=/usr/local/java

# User specific environment andstartup programs

exportORACLE_BASE=/u01/app/oracle

exportORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1

export ORA_CRS_HOME=/u01/app/crs

exportORACLE_PATH=$ORACLE_BASE/dba_scripts/common/sql:.:$ORACLE_HOME/rdbms/admin

export CV_JDKHOME=/usr/local/java

# Each RAC node must have aunique ORACLE_SID. (i.e. racdb1,racdb2,...)

exportORACLE_SID=racdb1

exportPATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin

exportPATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin

export PATH=${PATH}:$ORACLE_BASE/dba_scripts/common/bin

export ORACLE_TERM=xterm

exportTNS_ADMIN=$ORACLE_HOME/network/admin

exportORA_NLS10=$ORACLE_HOME/nls/data

exportNLS_DATE_FORMAT="DD-MON-YYYY HH24:MI:SS"

exportLD_LIBRARY_PATH=$ORACLE_HOME/lib

export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib

exportLD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib

export CLASSPATH=$ORACLE_HOME/JRE

exportCLASSPATH=${CLASSPATH}:$ORACLE_HOME/jlib

exportCLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib

exportCLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib

export THREADS_FLAG=native

export TEMP=/tmp

检测nobody帐号：

export TMPDIR=/tmp

# id nobody

uid=99(nobody) gid=99(nobody)groups=99(nobody)

如果nobody不存在，需要增加：

# /usr/sbin/useradd nobody

5.安装openfiler并创建相关卷：

6.在各个节点上创建相关的目录：

# mkdir -p/u01/app/oracle

# chown -Roracle:oinstall /u01/app/oracle

# chmod -R 775/u01/app/oracle

# mkdir -p/u01/app/crs

# chown -Roracle:oinstall /u01/app/crs

# chmod -R 775/u01/app/crs

# mkdir -p /u02

# chown -Roracle:oinstall /u02

# chmod -R 775 /u02

7.在各个节点上识别iscsi卷

1)在各个节点安装iscsi的initator：

[root@ora10racn1Server]# rpm -Uvh iscsi-initiator-utils-6.2.0.872-10.0.1.el5.x86_64.rpm

warning:iscsi-initiator-utils-6.2.0.872-10.0.1.el5.x86_64.rpm: Header V3 DSA signature:NOKEY,key ID 1e5e0159

Preparing...########################################### [100%]

packageiscsi-initiator-utils-6.2.0.872-10.0.1.el5.x86_64 is already installed

2)在各个节点上启动iscsi的进程：

[root@ora10racn1Server]# service iscsid start

Starting iSCSI daemon:

[ OK ]

3)在各个节点上搜索openfiler上的相关卷：

[root@ora10racn1Server]# iscsiadm -m discovery -tsendtargets -p 192.168.2.110

192.168.2.110:3260,1iqn.2006-01.com.openfiler:racdb.asm2

192.168.0.110:3260,1iqn.2006-01.com.openfiler:racdb.asm1

[root@ora10racn1 Server]# iscsiadm -m node -Tiqn.2006-01.com.openfiler:racdb.crs1 -p 192.168.2.110 -l

Logging in to [iface: default,target:iqn.2006-01.com.openfiler:racdb.crs1,portal: 192.168.2.110,3260]

[root@ora10racn1 Server]# iscsiadm -m node -Tiqn.2006-01.com.openfiler:racdb.asm1 -p 192.168.2.110 -l

[root@ora10racn1 Server]# iscsiadm -m node -Tiqn.2006-01.com.openfiler:racdb.asm2 -p 192.168.2.110 -l

[root@ora10racn1 Server]# iscsiadm -m node -Tiqn.2006-01.com.openfiler:racdb.crs1 -p 192.168.2.110 --op update -nnode.startup -v automatic

[root@ora10racn1 Server]# iscsiadm -m node -Tiqn.2006-01.com.openfiler:racdb.asm1 -p 192.168.2.110 --op update -nnode.startup -v automatic

[root@ora10racn1 Server]# iscsiadm -m node -Tiqn.2006-01.com.openfiler:racdb.asm2 -p 192.168.2.110 --op update -nnode.startup -v automatic

5)在各个节点上建立永久性连接规则，以保证自动连接时设备号不受连接顺序影响：

(cd /dev/disk/by-path; ls -l *openfiler* | awk '{FS=" "; print$9 " " $10 " " $11}')

ip-192.168.2.110:3260-iscsi-iqn.2006-01.com.openfiler:racdb.asm1-lun-0-> ../../sdc

ip-192.168.2.110:3260-iscsi-iqn.2006-01.com.openfiler:racdb.asm2-lun-0-> ../../sdd

ip-192.168.2.110:3260-iscsi-iqn.2006-01.com.openfiler:racdb.crs1-lun-0-> ../../sdb

创建连接规则：

[root@ora10racn1 rules.d]# vi /etc/udev/rules.d/55-openiscsi.rules

KERNEL=="sd*",BUS=="scsi",PROGRAM="/etc/udev/scripts/iscsidev.sh%b",SYMLINK+="iscsi/%c/part%n"

创建连接规则使用的脚本：

[root@ora10racn2 Server]# mkdir -p /etc/udev/scripts

[root@ora10racn2 scripts]# vi /etc/udev/scripts/iscsidev.sh

#!/bin/sh

# FILE: /etc/udev/scripts/iscsidev.sh

BUS=${1}

HOST=${BUS%%:*}

[ -e /sys/class/iscsi_host ] || exit 1

file="/sys/class/iscsi_host/host${HOST}/device/session*/iscsi_session*/targetname"

target_name=$(cat ${file})

# This is not an open-scsi drive

if [ -z "${target_name}" ]; then

exit 1

# Check if QNAP drive

check_qnap_target_name=${target_name%%:*}

if [ $check_qnap_target_name = "iqn.2004-04.com.qnap" ]; then

target_name=`echo"${target_name%.*}"`

echo "${target_name##*.}"

"iscsidev.sh" [New] 25L,507C written

[root@ora10racn2 scripts]#chmod 755 /etc/udev/scripts/iscsidev.sh

重新启动iscsi服务：

[root@ora10racn2 scripts]# service iscsi stop

Logging out of session [sid: 1,191);">Logging out of session [sid: 2,191);">Logging out of session [sid: 3,target:iqn.2006-01.com.openfiler:racdb.asm2,191);">Logout of [sid: 1,portal:192.168.2.110,191);">Logout of [sid: 2,191);">Logout of [sid: 3,191);">Stopping iSCSI daemon:

6)在一个节点上为iSCSI卷创建分区：（意：只能在一个节点上行）

[root@ora10racn1 rules.d]# fdisk /dev/iscsi/crs1/part

Device contains neither a valid DOS partition table,nor Sun,SGI or OSFdisklabel

Building a new DOS disklabel. Changes will remain in memory only,

until you decide to write them. After that,of course,the previous

content won't be recoverable.

7)在各个节点上对分区进行检验：

[root@ora10racn1 rules.d]# partprobe

[root@ora10racn1 rules.d]# fdisk -l

Disk /dev/sda: 53.6 GB,53687091200 bytes

ip-192.168.2.110:3260-iscsi-iqn.2006-01.com.openfiler:racdb.crs1-lun-0-part1-> ../../sdd1

8.配置各个节点的内核参数：

[root@ora10racn1 ~]# sysctl -p

net.ipv4.ip_forward = 0

net.ipv4.conf.default.rp_filter = 1

net.ipv4.conf.default.accept_source_route = 0

kernel.sysrq = 0

kernel.core_uses_pid = 1

net.ipv4.tcp_syncookies = 1

kernel.msgmnb = 65536

kernel.msgmax = 65536

kernel.shmmax = 4294967295

kernel.shmall = 268435456

net.core.rmem_default = 1048576

net.core.rmem_max = 1048576

net.core.wmem_default = 262144

net.core.wmem_max = 262144

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 65536

net.ipv4.ip_local_port_range = 1024 65000

[root@ora10racn1 ~]#cat >>/etc/security/limits.conf <<EOF

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

EOF

[root@ora10racn1 ~]#cat >> /etc/pam.d/login<<EOF

session required /lib/security/pam_limits.so

EOF

将下面一段加入到/etc/profile文件的末尾：

if [ $USER = "oracle"]; then

if [ $SHELL = "/bin/ksh" ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

umask 022

9.配置各个节点的hangcheck-timer:

1)检查是否安装了该模块：

[root@ora10racn1 ~]#find /lib/modules -name"hangcheck-timer.ko"

/lib/modules/2.6.18-274.el5/kernel/drivers/char/hangcheck-timer.ko

/lib/modules/2.6.32-200.13.1.el5uek/kernel/drivers/char/hangcheck-timer.ko

2)配置hangcheck-timer的两个参数：

[root@ora10racn1 ~]#echo "options hangcheck-timerhangcheck_tick=30 hangcheck_margin=180" >>/etc/modprobe.conf

3)手动加载hangcheckkernel 模块：

[root@ora10racn1 ~]# echo"/sbin/modprobe hangcheck-timer" >> /etc/rc.local

[root@ora10racn1 ~]#modprobehangcheck-timer

[root@ora10racn1 ~]# grepHangcheck /var/log/messages | tail -2

May 16 17:10:22 ora10racn1 kernel: Hangcheck: startinghangcheck timer 0.9.0 (tick is 60 seconds,margin is 180 seconds).

May 16 17:10:22 ora10racn1 kernel: Hangcheck: Usingget_cycles().

10. 配置各个节点间的信任关系：

? 在节点1上：

[root@ora10racn2 scripts]# su - oracle

[oracle@ora10racn2 ~]$ mkdir -p ~/.ssh

[oracle@ora10racn2 ~]$ chmod 700 ~/.ssh

11. 在各个节点oracle帐号的.bash_profile中增加下段以disable stty：

if [ -t 0 ]; then

stty intr ^C

12. 在各个节点的图形化界面中diskable SELinux

#/usr/bin/system-config-securitylevel &

13. 在各个节点安装并配置ocfs2：

1)安装ocfs2

[root@ora10racn2 Server]# pwd

/media/OL5.7 x86_64dvd 20110728/Server

[root@ora10racn2Server]# ls -l ocfs2*

-rw-r--r-- 1 rootroot 328649 Jul 26 2011ocfs2-2.6.18-274.el5-1.4.8-2.el5.x86_64.rpm

package ocfs2console-1.6.3-2.el5.x86_64is already installed

[root@ora10racn2Server]#

2)diskable SELinux

[root@ora10racn2Server]# /usr/bin/system-config-securitylevel &

3)在两个节点上配置OCFS2

[root@ora10racn1Server]#ocfs2console &

依次【Cluster】-->【Configure Nodes】-->【add】，在每个节点上都要增加两个节点信息，注意此时虽然IP选用的是心跳IP，但hostname用的是主机名称（即hostname命令的返回值）

配置后的结果写入到文件/etc/ocfs2/cluster.conf中

node:

ip_port = 7777

ip_address = 10.10.0.131

number = 0

name = ora10racn1.ccz.com

cluster = ocfs2

ip_port = 7777

ip_address = 10.10.0.132

number = 1

name = ora10racn2.ccz.com

cluster:

node_count = 2

name = ocfs2

注意：如果在用ocfs2console增加节点时报以下错误：

o2cb_ctl: Unable toaccess cluster service while creating node

Could not add nodenode1

则可以先将/etc/ocfs2/cluster.conf改名，然后使用ocfs2console重新加：

此时可以查看o2cb服务：

[oracle@ora10racn1 ~]$/etc/init.d/o2cb status

Driver for"configfs": Loaded

Filesystem"configfs": Mounted

Stack glue driver:Loaded

Stack plugin"o2cb": Loaded

Driver for"ocfs2_dlmfs": Loaded

Filesystem"ocfs2_dlmfs": Mounted

Heartbeat deadthreshold = 31

Network idle timeout: 30000

Network keepalive delay: 2000

Network reconnect delay: 2000

Checking O2CBheartbeat: Active

4)修改o2cb的配置（只需要在一个节点上执行），将heartbeat deadthreshold从缺省的31秒改为61秒：

[root@ora10racn1 ~]# /etc/init.d/o2cb offline ocfs2

Stopping O2CB clusterocfs2: OK

[root@ora10racn1 ~]# /etc/init.d/o2cb unload

Unloading module"ocfs2_stack_o2cb": OK

Unmounting configfsfilesystem: OK

Unloading module"configfs": OK

[root@ora10racn1 ~]# /etc/init.d/o2cb configure

Configuring the O2CBdriver.

This will configurethe on-boot properties of the O2CB driver.

The followingquestions will determine whether the driver is loaded on

boot. The current values will be shown in brackets('[]'). Hitting

<ENTER> withouttyping an answer will keep that current value.Ctrl-C

will abort.

Starting O2CB clusterocfs2: OK

检查修改结果：

Stack plugin "o2cb":Loaded

Heartbeat deadthreshold = 61

Checking O2CB heartbeat:Active

5)格式化OCFS2文件系统（只能在一个节点上执行）：

[root@ora10racn1 ~]# mkfs.ocfs2 -b 4k -C 32k -N 4 -L oracrsfiles/dev/iscsi/crs1/part1

mkfs.ocfs2 1.6.3

mkfs.ocfs2 successful

6)加载ocfs2文件系统（需要在两个节点上运行）：

[root@ora10racn1 ~]# mount -t ocfs2 -o datavolume,nointr -L"oracrsfiles" /u02

[root@ora10racn1 ~]# mount

/dev/mapper/VolGroup00-LogVol00on / type ext3 (rw)

ocfs2_dlmfs on /dlmtype ocfs2_dlmfs (rw)

/dev/sdd1 on/u02 type ocfs2 (rw,_netdev,datavolume,heartbeat=local)

7)在两个节点上修改/etc/fstab以让系统启动时自动加载ocfs2文件系统：

[root@ora10racn1 ~]# vi /etc/fstab

/dev/VolGroup00/LogVol00/ ext3defaults 1 1

LABEL=/boot /boot ext3 defaults 1 2

tmpfs /dev/shm tmpfs defaults 0 0

devpts /dev/pts devpts gid=5,mode=620 0 0

sysfs /sys sysfs defaults 0 0

proc /proc proc defaults 0 0

/dev/VolGroup00/LogVol01swap swap defaults 0 0

/home/swap swap swapdefaults 0 0

192.168.2.110:/mnt/nfs4backup/nfs4backup/nfs4backup /mnt/share nfsrw,vers=3,wsize=32768 00

LABEL=oracrsfiles /u02 ocfs2 _netdev,nointr 0 0

8)在两个节点上检查o2cb在各个运行级别上的运行设置：

[root@ora10racn1 ~]# chkconfig --list o2cb

o2cb 0:off 1:off2:on3:on 4:on 5:on 6:off

9)在一个节点上检查并修正ocfs2文件系统的所有者属性及权限属性：

[root@ora10racn1 /]# ls -ld /u02

drwxr-xr-x 3 root root 3896 May 16 21:54 /u02

[root@ora10racn1 /]# chown oracle:oinstall /u02

[root@ora10racn1 /]# chmod 775 /u02

drwxr-xr-x 3 oracle oinstall 3896 May 16 21:54 /u02

10)创建oracleclusterware 的相关目录（只需在一个节点上运行）：

[root@ora10racn1 ~]# mkdir -p /u02/oradata/racdb

[root@ora10racn1 ~]# chown -R oracle:oinstall /u02/oradata

[root@ora10racn1 ~]# chmod -R 775 /u02/oradata

[root@ora10racn1 ~]# ls -l /u02/oradata

drwxr-xr-x 2 oracleoinstall 3896 May 16 22:01 racdb

14. 在两个节点分别安装ASMLib

1)安装，其中前两个包在OLE5.7的介质中有，可直接安装，第三个需要到oracle网站下载：

[root@ora10racn1Server]# rpm -Uvhoracleasm-2.6.18-274.el5-2.0.5-1.el5.x86_64.rpm

oracleasm-support-2.1.7-1.el5.x86_64.rpm

2:oracleasm-2.6.18-274.el###########################################[100%]

[root@ora10racn1Server]# cd /home/oracle

[root@ora10racn1oracle]# ls

database Desktoporacleasmlib-2.0.4-1.el5.x86_64.rpm

[root@ora10racn1oracle]# rpm -Uvh oracleasmlib-2.0.4-1.el5.x86_64.rpm

warning:oracleasmlib-2.0.4-1.el5.x86_64.rpm: Header V3 DSA signature: NOKEY,191);"> 1:oracleasmlib########################################### [100%]

2)在两个节点上配置ASMLib：

[root@ora10racn1oracle]# /etc/init.d/oracleasm configure

Configuring the OracleASM library driver.

This will configurethe on-boot properties of the Oracle ASM library

driver. The following questions will determinewhether the driver is

loaded on boot andwhat permissions it will have. Thecurrent values

will be shown in brackets('[]'). Hitting <ENTER> withouttyping an

answer will keep thatcurrent value. Ctrl-C will abort.

Default user to ownthe driver interface []: oracle

Default group to ownthe driver interface []: oinstall

Start Oracle ASMlibrary driver on boot (y/n) [n]: y

Scan for Oracle ASMdisks on boot (y/n) [y]: y

Writing Oracle ASMlibrary driver configuration: done

Initializing theOracle ASMLib driver: [ OK ]

Scanning the systemfor Oracle ASMLib disks: [ OK ]

3)创建ASM磁盘（只需在一个节点上执行创建，在其余节点上扫描即可）：

节点一：

[root@ora10racn1oracle]# /etc/init.d/oracleasm listdisks

[root@ora10racn1oracle]# /etc/init.d/oracleasm createdisk VOL1/dev/iscsi/asm1/part1

Marking disk"VOL1" as an ASM disk: [OK ]

[root@ora10racn1oracle]# /etc/init.d/oracleasm createdisk VOL2 /dev/iscsi/asm2/part1

Marking disk"VOL2" as an ASM disk: [OK ]

[root@ora10racn1oracle]# /etc/init.d/oracleasm listdisks

VOL1

VOL2

节点二：

[root@ora10racn2oracle]# /etc/init.d/oracleasm listdisks

[root@ora10racn2oracle]# /etc/init.d/oracleasm scandisks

Scanning the systemfor Oracle ASMLib disks: [ OK ]

VOL2

15. 安装cluster软件前的预检：

1)在两个节点上安装cvuqdisk（只有RHEL需要）

[oracle@ora10racn1 ~]$su -

Password:

[root@ora10racn1 ~]# rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})n"|grep cvuqdisk

[root@ora10racn1 ~]# cd /home/oracle/ clusterware/rpm

[root@ora10racn1 rpm]#ls

cvuqdisk-1.0.1-1.rpm

[root@ora10racn1 rpm]# rpm -Uvh cvuqdisk-1.0.1-1.rpm

1:cvuqdisk########################################### [100%]

[root@ora10racn1 rpm]#scp ./cvuqdisk-1.0.1-1.rpm ora10racn2.ccz.com:/home/oracle

Are you sure you wantto continue connecting (yes/no)? yes

root@ora10racn2.ccz.com'spassword:

cvuqdisk-1.0.1-1.rpm

[root@ora10racn2oracle]# rpm -Uvh cvuqdisk-1.0.1-1.rpm

Preparing... ###########################################[100%]

1:cvuqdisk########################################### [100%]

2)安装前检测（在oracle帐号下执行，且只需在一个节点上运行）：

[oracle@ora10racn1cluvfy]$ cd /home/oracle/clusterware/cluvfy

[oracle@ora10racn1cluvfy]$ mkdir -p jdk14

[oracle@ora10racn1cluvfy]$ unzip jrepack.zip -d jdk14

[oracle@ora10racn1cluvfy]$ export CV_HOME=/home/oracle/clusterware/cluvfy[oracle@ora10racn1 cluvfy]$ exportCV_JDKHOME=/home/oracle/clusterware/cluvfy/jdk14[oracle@ora10racn1 cluvfy]$ ./runcluvfy.sh stage-pre crsinst -n ora10racn1,ora10racn2 -verbose

在检测中报

Check: Userequivalence for user "oracle"

Node NameComment

------------------------------------ ------------------------

ora10racn2 passed

ora10racn1 failed

Result: Userequivalence check failed for user "oracle".

WARNING:

User equivalence isnot set for nodes:

ora10racn1

Verification willproceed with nodes:

ora10racn2

这是因为在设置用户等效性后，第一次运行需要确认，而系统将这个确认视作失败，因此应手动先在各个节点上对所有节点（包括自身）进行下测试并确认，以确保第二次测试无需确认：

[oracle@ora10racn1 cluvfy]$ sshora10racn1 date

The authenticity ofhost 'ora10racn1 (192.168.0.131)' can't be established.

Warning: Permanentlyadded 'ora10racn1' (RSA) to the list of known hosts.

Thu May 17 08:45:40CST 2012

[oracle@ora10racn1 cluvfy]$ sshora10racn2 date

Thu May 17 08:45:55CST 2012

[oracle@ora10racn1 cluvfy]$ sshora10racn1 date

Thu May 17 08:50:10CST 2012

再次进行检测，遇到报错：

ERROR:

Could not find asuitable set of interfaces for VIPs.

Result: Nodeconnectivity check failed.

根据oracle文档（338924.1），这是一个bug，可以忽略。

3)通过CVU对系统硬件及操作系统进行检测：

[oracle@ora10racn1 cluvfy]$ ./runcluvfy.sh stage -post hwos -n ora10racn1,ora10racn2-verbose

Performing post-checksfor hardware and operating system setup

Checking nodereachability...

......

/dev/sdd ora10racn2ora10racn1

Shared storage checkwas successful on nodes "ora10racn2,ora10racn1".

Post-check forhardware and operating system setup was unsuccessful on all the nodes.

检测结果中除了VIP错误（忽略），还有一个warning，这个warning是因为CVU调用了linux的smartctl，而smartctl不能返回iscsi设备的序列号所致，不影响RAC的安装和使用，忽略。

16. 安装clusterware（只需要在一个节点的oracle帐号下运行即可）：

注意此处需要将crshome的路径做下修改，不要和oracle的home重合了：

根据实际情况增加节点：

根据情况调整网卡设置，其中eth1是连接存储的网卡，此处我单独设置成DoNotUse：

这只ocr及voting disk的存储路径：

注意：在执行root.sh前先如下修复下srvctl及vipca，否则报错，在实行root.sh后需要在图形界面中以root身份调用vipca配置vip，否则OUI仍然会报错：

分别在两个节点按顺序以root身份run相应脚本，但在最后一个节点run最后一个脚本root.sh时有一个报错：

CSS is active on allnodes.

Waiting for the OracleCRSD and EVMD to start

Oracle CRS stackinstalled and running under init(1M)

Running vipca(silent)for configuring nodeapps

/u01/app/crs/jdk/jre//bin/java:error while loading shared libraries: libpthread.so.0: cannot open sharedobject file: No such file or directory

经查，这是一个oracle的bug，解决方法见：

http://hi.baidu.com/heroofhero/blog/item/76747032361fc84dac4b5f09.html

修复：

? /u01/app/crs/bin/vipca:

152 exportLD_LIBRARY_PATH

153 ;;

154 esac

155

156 unset LD_ASSUME_KERNEL

157

158ARGUMENTS=""

159 NUMBER_OF_ARGUMENTS=$#

160 if [ $NUMBER_OF_ARGUMENTS -gt 0 ]; then

161 ARGUMENTS=$*

162 fi

/u01/app/crs/bin/srvctl:

166 #Remove this workaround when the bug 3937317 is fixed

167 LD_ASSUME_KERNEL=2.4.19

168 export LD_ASSUME_KERNEL

169 unset LD_ASSUME_KERNEL

170

171 # Run ops control utility

解决后回到原OUI中点击OK继续。

17. 安装oracle软件，注意只安装软件，不创建数据库：

18. 在两个节点上修正$ORACLE_HOME/bin/srvctl

同安装clusterware后对$CRS_HOME/bin/srvctl做的修正一样，需对$ORACLE_HOME/bin/srvctl进行修正：

LD_ASSUME_KERNEL=2.4.19

exportLD_ASSUME_KERNEL

unsetLD_ASSUME_KERNEL

19. 创建监听起及配置naming method（只需在一个节点运行）

20. 创建cluster数据库：

1)创建前的预检：

[oracle@ora10racn1cluvfy]$ env|grep CV

CV_JDKHOME=/home/oracle/clusterware/cluvfy/jdk14

CV_HOME=/home/oracle/clusterware/cluvfy

[oracle@ora10racn1cluvfy]$ pwd

/home/oracle/clusterware/cluvfy

[oracle@ora10racn1 cluvfy]$ ./runcluvfy.sh stage-pre dbcfg -n ora10racn1,ora10racn2 -d ${ORACLE_HOME} -verbose

预检中除了前面出现过的VIP问题以外，没有其他问题，该VIP问题可以忽略。

2)用dbca创建数据库：

在创建的过程中注意，ASM的spfile缺省位置由于不是共享存储，应改成共享存储位置，如图：

在创建ASM实例时报错：ORA-27125:unable to create shared memory segment

解决的办法是将dba的用户组加入到文件/proc/sys/vm/hugetlb_shm_group

[root@rac2 ~]# idoracle

uid=500(oracle)gid=501(oinstall)groups=501(oinstall),502(dba),503(asmadmin),504(oper)

[root@rac2 ~]#more/proc/sys/vm/hugetlb_shm_group

下面用root执行下面的命令，将dba组添加到系统内核中：

[root@rac2 ~]# echo502 >/proc/sys/vm/hugetlb_shm_group

具体参见：http://blog.csdn.net/tianlesoftware/article/details/7309046

3)创建磁盘组时注意修改下磁盘路径:

如使用缺省的ORCL:VOL*，将会导致机器HANG住。

4)创建成功：

21. 创建TAF服务：

[oracle@ora10racn1 ~]$dbca&

注意新建的taf服务不要带域名，否则会报错。

设置taf服务在系统启动时自动启动：

[oracle@ora10racn2bash]$ srvctl enable service -d racdb -s racdb_taf

查看taf服务的状态：

[oracle@ora10racn2bash]$srvctl config service -d racdb -s racdb_taf -a

racdb_tafPREF: racdb1 racdb2 AVAIL: TAF: basic

22. 重新编译数据库对象：

$ sqlplus / as sysdba

SQL>@?/rdbms/admin/utlrp.sql

23. 开启系统archive模式：

1)在一号节点上关闭RAC设置：

SYS@racdb1 SQL>showparameter cluster_database

cluster_database boolean TRUE

cluster_database_instances integer 2

SYS@racdb1SQL>alter system set cluster_database=falsescope=spfile sid='racdb1';

2)shutdown RAC上所有实例：

[oracle@ora10racn1admin]$ srvctl stop database -d racdb

[oracle@ora10racn1admin]$ crs_stat -t

24. 建立统一的password文件：

1)将一个节点上的ASM及RDBMS的口令文件移到共享文件系统上：

oracle@ora10racn2dbs]$ cd $ORACLE_HOME/dbs

[oracle@ora10racn2dbs]$ ls

2)在各个节点建立到共享口令文件的软连接：

[oracle@ora10racn2dbs]$ pwd

/u01/app/oracle/product/10.2.0/db_1/dbs

[oracle@ora10racn2dbs]$ ln -s /u02/oradata/racdb/dbs/orapw+ASM/u01/app/oracle/product/10.2.0/db_1/dbs/orapw+ASM2

[oracle@ora10racn2dbs]$ ln -s /u02/oradata/racdb/dbs/orapwracdb/u01/app/oracle/product/10.2.0/db_1/dbs/orapwracdb2

[oracle@ora10racn2dbs]$ ls -l
