1 安装 Veritas Storage Foundation

1.1 下载软件

http://go.symantec.com/vcsmc

SF for RAC Release 5.1 on LINUX

对应软件包 VRTS_SF_HA_Solutions_5.1_PR1_RHEL5_SLES10_x64.tar.gz

Veritas Enterprise Administrator 3.4.15.0 (Linux)

对应软件包 VRTSobgui-3.4.15.0-0.i686.rpm

VCS Cluster Manager Java_Console 5.1 (Linux)

对应软件包 VCS_Cluster_Manager_Java_Console_5.1_for_Linux.rpm

1.2 准备工作

# 软件要求

Software	Version
Database	Oracle RAC 11g Release 2
Operating system	Red Hat Enterprise Linux 5 (RHEL 5) Update 3 or later Oracle Enterprise Linux 5.3 (OEL 5.3) or later SUSE Linux Enterprise Server 10 with SP2 (SLES 10 SP2) SUSE Linux Enterprise Server 10 with SP3 ( SLES 10 SP3)

# 配置/etc/hosts

在2 台主机/etc/hosts 上增加各自的IP

192.168.0.49 host1

192.168.0.50 host2

 

# 配置2 个节点root 用户的ssh 信任

 

# 配NTP

 

# 准备共享磁盘

 

存储上的 lun 必须对所有节点可见。

共享存储必须支持SCSI-3 Persistent Reservations (PR ，永久保留功能).

SCSI-3 PR 就是一组SCSI 命令集，用在多个系统访问一个共享存储的时候协调之用。

安装完 SF 后可用 vxfentsthdw 可做检查。

 

/opt/VRTS/bin/vxfentsthdw

 

# cd /opt/VRTS/bin

#./vxfentsthdw

 

VERITAS vxfentsthdw version 5.1.001.000-RP1 Linux

The utility vxfentsthdw works on the two nodes of the cluster. The utility verifies that the shared storage one intends to use isconfigured to support I/O fencing. It issues a series of vxfenadm commands to setup SCSI-3 registrations on the disk, verifies the registrations on the disk, and removes the registrations from the disk.

******** WARNING!!!!!!!! ********

THIS UTILITY WILL DESTROY THE DATA ON THE DISK!!

Do you still want to continue : [y/n] (default: n) y

Please respond with (y/n) n

 

# I/O fencing 策略

 

对于采用 cluster file system 的 veritas ha 方案，一定要采用共享磁盘做 I/O fencing ；

对于单机的 file system ，在确保有 2 个直连网线和 1 个 bond 的业务网络的情况下，可以不考虑 I/O fencing 的策略。

Make sure that the I/O fencing coordinator disks meet the following requirements:

* For disk-based I/O fencing, you must have three coordinator disks.

* The coordinator disks can be raw devices, DMP devices, or iSCSI devices.

You must use DMP disk policy for iSCSI-based coordinator disks.

* Each of the coordinator disks must use a physically separate disk or LUN.

Symantec recommends using the smallest possible LUNs for coordinator disks.

* The coordinator disks must support SCSI-3 persistent reservations.

*Symantec recommends using hardware-based mirroring for coordinator disks.

* Coordinator disks must not be used to store data or must not be included in disk groups that store user data.

* Coordinator disks cannot be the special devices that array vendors use. For example, you cannot use EMC gatekeeper devices as coordinator disks.

 

 

# 配置环境变量

 

vi /root/.bash_profile

export MANPATH=$MANPATH:/opt/VRTS/man

PATH=$PATH:$HOME/bin

PATH=$PATH:/

/usr/lib/vxvm/bin:/opt/VRTSvcs/bin:/

/opt/VRTS/bin:/opt/VRTSvcs/rac/bin:/

/opt/VRTSob/bin;

export PATH

# 配置 linux I/O 调度策略

Symantec recommends using the Linux 'deadline' I/O scheduler for database

workloads. Configure your system to boot with the 'elevator=deadline' argument

to select the 'deadline' scheduler.

查看当前的 IO 调度策略，默认选择 CFQ 做为 I/O 调度器

cat /sys/block/sd*/queue/scheduler

 

修改调度策略

vi /boot/grub/menu.lst

 

kernel /boot/vmlinuz-2.6.18-128.el5 ro root=LABEL=/

改为

kernel /boot/vmlinuz-2.6.18-128.el5 ro root=LABEL=/ elevator=deadline

 

重启OS ，检查是否修改生效。

 

# 网络要求

 

网络要求 1 个走交换机的业务网段， 1 个网线直连的私有网段。

 

私有网段的网口要用直连网线连接，作为首选心跳，争取可以配 2 条直连网线。

业务网络网卡要求 2 张独立网卡做 bond ，可以作为备用心跳线。

每个机器业务网段的 2 个 bond 网口分别上联到 2 个独立的网络交换机上面。

2 用 VEA 配置 Disk Group

用 veritas 的 VEA 图形界面划 Disk Group ， Volumes ，初始化 File System 。

2.1 安装 VEA

安装

rpm -ivh /root/source/VRTSobgui-3.4.15.0-0.i686.rpm

 

卸载

rpm -e VRTSobgui

 

安装完成后，要启动服务 vxsvcctrl

/opt/VRTSob/bin/vxsvcctrl activate

/opt/VRTSob/bin/vxsvcctrl start

 

本机配置Xmanager ，启动vea 图形界面

export DISPLAY=10.16.200.84:0

/opt/VRTSob/bin/vea &

 

[select profile] 用default ，之后选择[connect to a Host or Domain] ，

[host name] 选 localhost ， Connect Using root@localhost ，用本机 root 账号登陆，

进入vea 管理界面。

2.2 新建 DG

[Disk Group] --> 新建DG ，New Disk Group --> 填写Group Name ，选择要加入这个DG 的Disk ，其余默认配置，不用修改。

 

最后创建出 3 个 DG ： redodg ， archdg ， datadg 。

 

2.3 创建 Volumes 和 File System

[Volumes]-->[New Volume]--> 选择 DG-->Let VM decide what disks to use for this volume

 

每个DG 单独创建1 个volume ，用vxfs 文件系统格式化这个volume 。

 

Volume 的创建方式：

Concatenated Volume ，级联方式，创建 lv 时，用完 1 块盘，再用另外 1 块。

Striped Volume ，条带方式，指定 stripe size 和盘数 columns 。

 

我们要求建Volumn 时，stripe size 用128 ，columns 用所有的盘。

 

创建 lv_redodg

 

 

 

fs_redodg 配置

File system type ： vxfs

Blocksize ： 8k

Mount Point /redodg

不选择 {Add to file system table}

其他配置不动

 

 

 

 

lv_datadg

 

fs_datadg

 

 

lv_archdg

 

 

fs_archdg

 

 

#df –lh

/dev/vx/dsk/archdg/lv_redodg 200G 72M 198G 1% /archdg

2.4 在另外一个节点上配置 DG

先在本节点 umount filesystem ， deport dg ，

在另外1 个节点上import dg

[Disk Groups] -->Import Disk Group --> OK

 

Import DG 之后， Volumes 会自动激活，需要重新创建 File System

[Volumes]-->volume-->File System--> New File System

3 安装 oracle 软件，创建数据库

3 .1 安装 oracle 软件

参考Oracle 安装文档。

3 .2 用 Veritas 的 ODM 代替 Oracle 的 libodm 库

修改 Oracle 的libodm 库，指向 veritas 的 ODM ，之后创建 oracle 数据库。

 

刚安装完 Oracle 软件后的 oracle libodm

lrwxrwxrwx 1 oracle oinstall 20 Sep 6 05:34 libodm11.so -> /usr/lib64/libodm.so

 

替换为 veritas 的 ODM

 

#su - oracle

#cd $ORACLE_HOME/lib

#mv libodm11.so libodm11.so.oracle

#ln -s /usr/lib64/libodm.so libodm11.so

 

#ls -ltr libodm11*

lrwxrwxrwx 1 oracle oinstall 12 Aug 17 08:12 libodm11.so.oracle -> libodmd11.so

lrwxrwxrwx 1 oracle oinstall 20 Sep 6 05:34 libodm11.so -> /usr/lib64/libodm.so

 

3.3 手工 创建数据库

要注意spfile 需要放在存储上面。

4 用 VCM 配置 Veritas HA

4.1 安装 VCM 图形界面， 管理 VCS

安装

rpm -ivh /root/source/VCS_Cluster_Manager_Java_Console_5.1_for_Linux.rpm

 

卸载 VCM

rpm -e VRTScscm

打开图形界面

export DISPLAY=10.16.200.84:0

/opt/VRTSvcs/bin/hagui &

 

默认账号　admin/password

4. 2 增加服务组

Add Service Group

 

添加Service Group Name, 选择节点, Service Group Type 用默认 FailOver,

Templates 选择OracleGroup ，OK.

4. 3 增加资源组

在Service Group 中 Add Resource

 

添加资源的时候注意选择enabled

 

# 添加 DiskGroup 资源

4.4 在 resource 中设置 link 关系

 

4.5 ha 配置文件

所有的 ha 配置，最后都保存到 /etc/VRTSvcs/conf/config/main.cf

HA 监控配置

5.1 监控 oracle instance

默认监控脚本 /opt/VRTSagents/ha/bin/Oracle/SqlTest.pl

我们使用 /opt/VRTSagents/ha/bin/Oracle/SimpleTest.pl

 

SID dbsid

Owner oracle

Home /opt/oracle/products/11.1.0/db_1

Pfile

StartupOpt STARTUP_FORCE

ShutDownOpt IMMEDIATE

EnvFile 设置环境变量，不需要

AutoEndBkup true

User monitor

Pword monitor 密码会自动加密

Table veritas_update

MonSctipt ./bin/Oracle/SimpleTest.pl

DetailMonitor 1

Encoding

MonitorOption 0 Oracle Instance 的监控选项，默认为0 。0 为进程检查，1 为健康检查。10g 之前必须配置为0 。

 

 

-- 配置detail monitoring for Oracle

 

sqlplus ‘/as sysdba’

drop user monitor CASCADE;

 

create user monitor

revoke UNLIMITED TABLESPACE from monitor;

alter user monitor quota unlimited on USERS;

 

create table monitor.veritas_update( tstamp date );

insert into monitor.veritas_update (tstamp) values (sysdate);

commit;

 

在Ora_oracle 资源的配置项里面，要配置参数

 

User monitor

Pword monitor 密码会自动加密

Table veritas_update

MonSctipt ./bin/Oracle/SimpleTest.pl

DetailMonitor 1

 

在 Oracle 的配置项里面，配置 Oracle 实例监控间隔：

MonitorInterval 60

FaultOnMonitorTimeouts 2

MonitorTimeout 20

含义：

监控间隔60 秒，超时2 次fault ，超时时间20 秒，

1 次更新不成功开始报警，2 次连续更新不成功，就failover 。

也就是 update 80 秒不成功， fault ，开始切换。

/opt/VRTSagents/ha/bin/Oracle/SimpleTest.pl 这个脚本的动作 :

# SQL> connect <User>/<Pword>

# SQL> update <User>.<Table> set ( tstamp ) = SYSDATE;

# SQL> select TO_CHAR(tstamp, 'MON DD, YYYY HH:MI:SS AM')tstamp

# 2> from <User>.<Table>;

HA 切换

6.1 HA 切换日志

Veritas 所有的日志放在 /var/VRTSvcs/log/ 下面，

 

/var/VRTSvcs/log/engine_A.log HA 所有动作的详尽日志， 2 个节点同步生成。

/var/VRTSvcs/log/Oracle_A.log Oracle 资源的日志

 

Veritas HA 的日志条目按关键词分为 4 个级别： INFO/NOTICE/WARNING/ERROR ，

在 /var/VRTSvcs/log/engine_A.log 文件中监控 WARNING/ERROR 即可。

6.2 HA 切换测试

# 环境：

 

host1 和 host2 两个节点，资源，应用跑在 host1 。

有 eth1-4 ，共 4 个网口。 eth1 ， eth3 这 2 个独立网口用直连线做首选心跳， eth0 ， eth2 走业务，做 bond 后上联到 2 个网络交换机。

 

默认资源配置：

MonitorInterval 60s

OfflineMonitorInterval 300s

 

Oracle 资源参数配置 :

MonitorInterval 60 ，

FaultOnMonitorTimeouts 2 ，

MonitorTimeout 20

 

# 测试场景：

 

(1) host1 OS reboot

 

测试结果： 60 秒内发现问题，资源切换到 host2 。

 

(2) 网络测试

 

Ora_NIC 监控业务网卡bond0 ，Ora_IP 是VIP ，附在bond0:0

 

** 单独断掉心跳 eth1 ， eth3

 

ifdown eth1

ifup eth1

 

测试结果：对 ha 无影响， headbeat 链路会切换

 

** 单独断掉业务网卡

 

ifdown bond0

 

测试结果： down 掉 bond0 ，导致 Ora_NIC 资源 down 掉， vip 附在 bond0:0 上，业务 bond0 当掉，会导致 Ora_IP 当掉，监听 down ， oracle down ，资源切换到 host2

 

(3) 监听 down 掉

 

测试结果： 60 秒内发现问题，不做处理。

标记资源Faulted ，节点Partial Online 。

监听恢复 5 分钟后，会把资源标记为正常，节点状态 Online 。

 

(4) oracle shutdown abort

 

测试结果：资源正常切换到 host2

 

(5) db hang

 

测试结果： db 无法执行 update ， 60+20 秒内检测到，进行切换。

连续出现 2 次 update 超时事件就会切换。

常用命令

7.1 Veritas DMP

# 磁盘的多路径信息

 

vxdmpadm list dmpnode all |more

vxdmpadm list dmpnode dmpnodename=hds9500-alua0_0

 

#vxdmpadm -h list

Report detailed list of attributes associated with the specified entities such as DMP devices.

Usage:

vxdmpadm list dmpnode [all]

vxdmpadm list dmpnode [dmpnodename=<dmp-device-name>]

vxdmpadm list dmpnode [enclosure=<enclr-name>]

 

# 查看lun 信息

 

dmp 把磁盘初始化之后才能用vxdisk list 看到盘

 

#vxdisk list|more

DEVICE TYPE DISK GROUP STATUS

hds9500-alua0_0 auto:cdsdisk redovg01 redodg online

hds9500-alua0_1 auto:cdsdisk redovg02 redodg online

hds9500-alua0_2 auto:cdsdisk archvg01 archdg online

hds9500-alua0_3 auto:cdsdisk archvg02 archdg online

 

vxdisk list hds9500-alua0_0 可以显示这个 lun 的 path

7.2 Veritas VxVM

显示dg

#vxdg list

# vxdg list redodg

7.3 Veritas VCS

启动vcs

# hastart 在本地启动 ha

 

停止vcs

# hastop -all 停掉所有节点上的 vcs

# hastop -local 停止本节点上的 vcs ，也停掉本节点 running 的资源

# hastop -all -force 停止 vcs ，但保持所有资源可用

 

资源组

#hagrp -online myha -sys host1 把资源组 myha 在 host1 拉起来

#hagrp -offline myha -sys host1 资源组从 host1 离线

 

资源组切换

# hagrp -switch myha -to host2 资源从 host1 切换到 host 2

# tail -f /var/VRTSvcs/log/engine_A.log 查看切换日志

 

检查ha 状态

#hastatus ha 详细状态信息，包含每个资源

#hastatus -sum ha 基本情况

 

资源 fault 导致切换后，需要手工 clear 资源，才能使节点返回正常可切换状态。

#hares -clear Ora_Oracle -sys host1

#hares -clear Ora_IP -sys host1

 

资源组冻结

# hagrp -freeze myha 冻结 ha 后，维护资源不会导致 ha 切换。

# hagrp -unfreeze myha 解冻

 

探测资源

# hares -probe Ora_Oracle -sys host2 资源恢复正常后，需要探测一下， ha 状态才能正常。
