参考文档e10812 –page 66 :

Oracle® Grid Infrastructure

Installation Guide

11g Release 2 (11.2) for Linux

Vi /etc/fstab

/dev/shm 共享内存不足的处理

解决方法：

例如：为了将/dev/shm的大小增加到1GB，修改/etc/fstab的这行：默认的：

none /dev/shm tmpfs defaults 0 0

改成：

none /dev/shm tmpfs defaults,size=1024m 0 0

size参数也可以用G作单位：size＝1G。

重新mount /dev/shm使之生效：

# mount -o remount /dev/shm

或者：

# umount /dev/shm

# mount -a

马上可以用"df -h"命令检查变化。

参考e10812- page 139-140:

MEMORY_TARGET not supported on this system

Cause: On Linux systems, insufficient /dev/shm size for PGA and SGA.

If you are installing on a Linux system, note that Memory Size (SGA and PGA),

which sets the initialization parameter MEMORY_TARGET or MEMORY_MAX_

TARGET, cannot be greater than the shared memory file system (/dev/shm) on

your operating system.

Note: You should not have netdev in the mount instructions, or

vers=2. The netdev option is only required for OCFS file systems,

and vers=2 forces the kernel to mount NFS using the older version 2

protocol.

Interpreting CVU "Unknown" Output Messages Using Verbose Mode

A-4 Oracle Grid Infrastructure Installation Guide

Action: Increase the /dev/shm mountpoint size. For example:

# mount -t tmpfs shmfs -o size=4g /dev/shm

Also, to make this change persistent across system restarts, add an entry in

/etc/fstab similar to the following:

shmfs /dev/shm tmpfs size=4g 0

配置信任关系

设置SSH，

(The network must be configured first)

#for ‘grid’ user on both nodes

Su – grid

mkdir ~/.ssh

chmod 700 ~/.ssh

# Accept the default settings.

ssh-keygen -t rsa

ssh-keygen -t dsa

#on rac1, scp to another nodes

[grid@rac1 ~]$ cat ~/.ssh/id_ >> ./.ssh/authorized_keys

[grid@rac1 ~]$ cat ~/.ssh/id_ >> ./.ssh/authorized_keys

[grid@rac1 ~]$ ssh rac2 cat ~/.ssh/id_ >> ~/.ssh/authorized_keys

[grid@rac1 ~]$ ssh rac2 cat ~/.ssh/id_ >> ~/.ssh/authorized_keys

# input ‘yes’ and grid’s password

[grid@rac1 ~]$ scp ./.ssh/authorized_keys rac2:/home/grid/.ssh/

[grid@rac1 ~]$ $ ssh rac1 date

[grid@rac1 ~]$ $ ssh rac2 date

[grid@rac1 ~]$ $ ssh rac1prv date

[grid@rac1 ~]$ $ ssh rac2prv date

#on rac2

[grid@rac1 ~]$ $ ssh rac1 date

[grid@rac1 ~]$ $ ssh rac2 date

[grid@rac1 ~]$ $ ssh rac1prv date

[grid@rac1 ~]$ $ ssh rac2prv date

#same action for ‘oracle’ user on both nodes

Su – oracle

mkdir ~/.ssh

chmod 700 ~/.ssh

# Accept the default settings.

ssh-keygen -t rsa

ssh-keygen -t dsa

#on rac1, scp to another nodes

[oracle@rac2 ~]$ cat ~/.ssh/id_ >> ./.ssh/authorized_keys

[oracle@rac1 ~]$ cat ~/.ssh/id_ >> ./.ssh/authorized_keys

[oracle@rac1 ~]$ ssh rac2 cat ~/.ssh/id_ >> ~/.ssh/authorized_keys

[oracle@rac1 ~]$ ssh rac2 cat ~/.ssh/id_ >> ~/.ssh/authorized_keys

# input ‘yes’ and oracle’s password

[oracle@rac1 ~]$ scp ./.ssh/authorized_keys rac2:/home/oracle/.ssh/

[oracle@rac1 ~]$ $ ssh rac1 date

[oracle@rac1 ~]$ $ ssh rac2 date

[oracle@rac1 ~]$ $ ssh rac1prv date

[oracle@rac1 ~]$ $ ssh rac2prv date

#on rac2

[oracle@rac1 ~]$ $ ssh rac1 date

[oracle@rac1 ~]$ $ ssh rac2 date

[oracle@rac1 ~]$ $ ssh rac1prv date

[oracle@rac1 ~]$ $ ssh rac2prv date

NOTES: Enabling SSH User Equivalency for the Current Shell Session,

When running the OUI, it will need to run the secure shell tool commands (ssh and scp) without being prompted for a

pass phrase. Even though SSH is configured on both Oracle RAC nodes in the cluster, using the secure shell tool

commands will still prompt for a pass phrase.

[oracle@racnode1 .ssh]$ exec /usr/bin/ssh-agent $SHELL

[oracle@racnode1 .ssh]$ /usr/bin/ssh-add

Enter passphrase for /home/oracle/.ssh/id_rsa

Identity added: /home/oracle/.ssh/id_rsa (/home/oracle/.ssh/id_rsa)

Identity added: /home/oracle/.ssh/id_dsa (/home/oracle/.ssh/id_dsa)

These commands start the ssh-agent on the local node, and load the RSA and

DSA keys into the current session’s memory so that you are not prompted to use

pass phrases when issuing SSH commands.

安装ASM

/technology/tech/linux/asmlib/

if x86_64, related rpms need to be downloaded

rpm –ivh –replacefiles/--replacepkgs

This installation needs to be performed on both nodes in the RAC cluster as the root user account:

1. Error log recorded in : cat /var/log/oracleasm, [oracleasm update-driver] can update driver on-line.

2. SELINUX needs to be disabled : cat /etc/selinux/config

rpm -ivh *.rpm

[root@rac1 /]# /etc/init.d/oracleasm configure

Configuring the Oracle ASM library driver.

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

driver. The following questions will determine whether the driver is

loaded on boot and what permissions it will have. The current values

will be shown in brackets ('[]'). Hitting without typing an

answer will keep that current value. Ctrl-C will abort.

Default user to own the driver interface []: grid

Default group to own the driver interface []: asmadmin

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

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

Writing Oracle ASM library driver configuration: done

Initializing the Oracle ASMLib driver: [ OK ]

Scanning the system for Oracle ASMLib disks: [ OK ]

创建asm盘

Creating the ASM disks only needs to be done on one node in the

RAC cluster as the root user account. I will be running these

commands on linux1. On the other Oracle RAC node, you will need to

perform a scandisk to recognize the new volumes.

[root@rac1 /]# /etc/init.d/oracleasm createdisk CRS1 /dev/emcpowera1

Marking disk "CRS1" as an ASM disk: [ OK ]

[root@rac1 /]# /etc/init.d/oracleasm createdisk CRS2 /dev/emcpowera2

Marking disk "CRS2" as an ASM disk: [ OK ]

。。。

[root@rac1 /]# /etc/init.d/oracleasm createdisk DATA1 /dev/emcpowera5

Marking disk "DATA1" as an ASM disk: [ OK ]

[root@rac1 /]# /etc/init.d/oracleasm createdisk DATA2 /dev/emcpowera6

Marking disk "DATA2" as an ASM disk: [ OK ]

[root@rac1 /]# /etc/init.d/oracleasm createdisk DATA3 /dev/emcpowera7

Marking disk "DATA3" as an ASM disk: [ OK ]

[root@rac1 /]# /etc/init.d/oracleasm createdisk REC1 /dev/emcpowera8

Marking disk "REC1" as an ASM disk: [ OK ]

[root@rac1 /]# /etc/init.d/oracleasm createdisk REC2 /dev/emcpowera9

Marking disk "REC2" as an ASM disk: [ OK ]

On all other nodes in the RAC cluster, you must perform a scandisk to recognize the new volumes:

[root@rac2 /]# /etc/init.d/oracleasm scandisks

Scanning the system for Oracle ASMLib disks: [ OK ]

[root@rac2 /]# /etc/init.d/oracleasm listdisks

安装cvuqdisk包并验证

cvuqdisk RPM 包含在 Oracle Grid Infrastructure 安装介质上的 rpm 目录中

su – root

cd /$grid_install_folder/rpm/

[root@rac1 rpm] export CVUQDISK_GRP=oinstall

[root@rac1 rpm] rpm -e cvuqdisk

[root@rac1 rpm] rpm -ivh

使用 CVU 验证是否满足 Oracle 集群件要求

记住要作为 grid 用户在将要执行 Oracle 安装的节点 (racnode1) 上运行。此外，必须为 grid

用户配置通过用户等效性实现的 SSH

[if this machine has already installed other oracle database, you may have to check/modify /etc/ file]

inventory_loc=/oracle/app/oraInventory

inst_group=group

Su – grid

Cd /$grid_install_folder/

./ stage -pre crsinst -n rac1,rac2 -fixup -verbose

./ stage -pre crsinst -n rac1,rac2 –verbose

运行上述包时，必须用 oracle 用户，不能用 root ，同时，运行时可能会报一个 /tmp/bootstrap 不能被删除的错误，用 root 账号将此目录删除或改名即可。

使用 CVU 验证硬件和操作系统设置

./ stage -post hwos -n rac1,rac2 -verbose

[grid@rac1 grid]$ ./ stage -post hwos -n rac1,rac2 -verbose

With Oracle Clusterware 11g release 2, Oracle Universal Installer (OUI) detects when

the minimum requirements for an installation are not met, and creates shell scripts,

called fixup scripts, to finish incomplete system configuration steps. If OUI detects an

incomplete task, then it generates fixup scripts (). You can run the fixup

script after you click the Fix and Check Again Button.

You also can have CVU generate fixup scripts before installation

Install grid infrastructure on one NODE:

su - grid

./runInstaller

scan配置：

cluster scan: sanclusters

scanname: racscan

scanport: 1521

Sysasm/asm123

(A must to refer to grid user env.)

Disable all firewall or selinex:

service iptables stop

Apart from disabling Firewall, this might be with your /tmp directory in the second node while trying to copy

the installation files.

-- make sure you have same temporary directory name across the nodes.

-- do a chown -R grid:oinstall /tmp across all the nodes.
