曾经的这篇《WebSphere Information Integrator安装过程》是windows下的安装过程，图片么google相册被挡住了，我也懒得再改。

这次是在AIX下安装DB2 9.1版本，从准备操作补丁到修改内核参数，安装完整数据库。安装完DB2后安装DB2 Infosphere information Integrator（也就是之前的WebSphere Information Integrator）中的Replication Server。

DB2数据库安装准备

1、使用bootinfo –K来确认是否是64位内核。如果没有请按以下内容更改：

要切换至 64 位内核，需要 root 用户权限并应输入下列命令：

ln -sf /usr/lib/boot/unix_64 /unix

ln -sf /usr/lib/boot/unix_64 /usr/lib/boot/unix

bosboot -a

shutdown –Fr

2、安装操作补丁：

xlC.rte 8.0.0.4和 xlC.aix50.rte 8.0.0.8

• 技术级别（TL）5300-04 和 Service Pack (SP) 5300-04-02 及以上

在操作系统光盘可以找到安装，如果没有的话可以到IBM网站下载

3、建文件系统：

Lv名称 文件系统 描述 大小

数据库文件安装在 /默认的文件系统中

db2inst1lv /home/db2inst1 文件系统用于安装DB2实例 30GB(双机环境在共享盘)

① mklv –y db2inst1lv –t jfs2 rootvg 60 hdisk0

② crfs –v jfs2 –d db2inst1lv –m /home/db2inst1

db2fenc1lv /home/db2fenc1 文件系统用于安装DB2 软件 2GB(双机环境在共享盘)

① mklv –y db2fenc1lv –t jfs2 rootvg 4 hdisk0

② crfs –v jfs2 –d db2fenc1lv –m /home/db2fenc1

backlv /db2/back 文件系统用于DB2备份 30GB

① mklv –y backlv –t jfs2 rootvg 60 hdisk0

② crfs –v jfs2 –d backlv –m /db2/back

db2softlv /db2soft 用于原始db2程序和WII软件的放置 3GB

① mklv –y db2softlv –t jfs2 rootvg 6 hdisk0

② crfs –v jfs2 –d db2softlv –m /db2soft

db2log 用于放置db2日志文件

① mklv –y db2loglv –t jfs2 rootvg 6 hdisk0

② crfs –v jfs2 –d db2loglv –m /db2log

4、建用户和组

l 打开系统异步IO，通过SMITTY工具将异步状态置为Available,即

Smitty aio来改变机器的AIO状态为available

The state to be configured at system restart : available（重新启动机器）

l 您可以通过Smitty工具来创建用户和组，也可以通过下列命令来创建：

（1）建组

mkgroup id=400 db2iadm1

mkgroup id=410 db2fadm1

mkgroup id=420 db2asgrp

(2) 建用户

mkuser id=400 pgrp=db2iadm1 groups=db2iadm1 home=/home/db2inst1 db2inst1

passwd db2inst1

mkuser id=410 pgrp=db2fadm1 groups=db2fadm1 home=/home/db2fenc1 db2fenc1

passwd db2fenc1

mkuser id=420 pgrp=db2asgrp groups=db2asgrp home=/home/db2as db2as

passwd db2as

5、更改文件权限

  chown -R db2inst1:db2iadm1 /home/db2inst1

  chown -R db2fenc1:db2fadm1 /home/db2fenc1

chown –R db2inst1:db2iadm1 /db2/back /db2soft /db2log

6、上传安装文件包到 /db2soft

DB2_Enterprise_Svr_Ed_AIX_5L.tar

RepServ_9.1_AIX5.tar

v9fp4a_aix_universal_fixpack.tar

在/db2soft 建立目录

mkdir db2v9

mkdir v9fp4a

解压到 db2v9 repsv v9fp4a

cd db2v9

tar –xvf /db2soft/DB2_Enterprise_Svr_Ed_AIX_5L.tar

cd repsv

tar –xvf /db2soft/ RepServ_9.1_AIX5.tar

cd v9fp4a

tar –xvf /db2soft/ v9fp4a_aix_universal_fixpack.tar

7.安装DB2 cd db2v9

./db2setup ; 执行安装

选择db2 Enterprise Server Edition 点击 install new

点 next

选择 accept 点next

选择typical->next

选择 install DB2 Enterprise Server Edition on this computer -> next

指定目录/db2soft/v91 确保该目录下为空

选择 Existing user 指定 db2as

Create a DB2 isntance

Select single partition instance

Select Existing user : db2inst1

Select Existing user : db2fenc1

Select Do not prepare the DB2 tools catalog

Select do not set up your DB2 server to send notifications at this time

finish

OK

安装WII

Cd repsv

./iisetup

Next ->next

Select accept->next

Only select websphere Replication server

Select install the selected products

Next -> select existing db2 copy

自动选择 /db2/db2soft/v91

next

Only select English

Select do not configure any wrappers

finish

打补丁

Cd v9fp4a cd universal cd disk1

打补丁（v9fp4a_aix_universal_fixpack.tar.gz）:

确认各项db2服务停止(

su – db2inst1

db2stop force

su – db2as

db2admin stop

，然后进入对应的路径安装补丁fp12

cd fixpack

./installFixPak ; 此处要注意要区分大小写

输入路径

/db2soft/v9.1

安装结束，查看所有补丁包是否安装成功

安装修订包后的任务（Linux^® 和 UNIX^®）

安装修订包之后，必须绑定数据库实用程序和 DB2^® CLI 绑定文件。根据使用的数据库产品和修订包安装方法，还可能需要更新 DB2 实例和系统目录对象、重新启动 DB2 实例和 DB2 管理服务器以及启动 djxlink 命令。

执行下列操作：

1. 如果安装了 WebSphere^® Federation Server，则运行 djxlink 命令。

在安装修订包之后并且在运行 db2iupdt 之前，执行下列任务：

a. 作为 root 用户登录。

b. 除去或重命名文件 djxlink.out，它位于 DB2DIR/lib 目录中，其中 DB2DIR 是 DB2 安装目录。

c. 确保设置了当前环境或 db2dj.ini 文件中的所有相应变量。 例如，如果要使用联合服务器连接至 Oracle 数据源，则将环境变量 ORACLE_HOME 设置为 Oracle 主目录。

d. 运行以下命令：

djxlink

2. 更新实例以使用新级别的 DB2。

如果安装了修订包来更新现有安装，则必须执行此任务。如果安装了修订包来创建新安装，则不需要执行此任务。如果有多个 DB2 副本，则更新安装了修订包的 DB2 副本中的实例。安装修订包之后，必须更新 DB2 副本中的所有实例。

执行下列步骤：

a. 作为 root 用户登录。

b. 通过发出以下命令来确定与 DB2 副本关联的实例：

DB2DIR/instance/db2ilist

其中 DB2DIR 表示 DB2 副本的安装位置。

c. 如果对 db2profile 或 db2cshrc 脚本进行了任何更改，则备份这些脚本或者将更改分别复制到 userprofile 和 usercshrc 脚本中。

因为 db2iupdt 命令会覆盖 db2profile 和 db2cshrc 脚本，所以必须执行此操作。它不会覆盖 userprofile 和 usercshrc 脚本。

d. 对每个实例发出以下命令：

DB2DIR/instance/db2iupdt iname

其中 iname 表示实例名，而 DB2DIR 表示 DB2 副本的安装位置。

e. 如果 DB2 管理服务器（DAS）属于安装了修订包的 DB2 副本，则发出以下命令：

DB2DIR/instance/dasupdt

其中 DB2DIR 是 DB2 副本的安装位置。如果此 DB2 副本现在正以比所有其他 DB2 副本更新的修订包级别运行，则考虑更新 DAS 以便它属于此 DB2 副本。

3. 可选：更新数据库中的系统目录对象以支持该修订包。

对于 DB2 版本 9.1 修订包 2 或更新版本，如果要使用特定于该修订包的功能，则强烈建议您执行此任务。由于没有现有数据库，所以在安装了修订包来创建新安装的情况下，不需要执行此任务。

对 DB2 副本中的每个实例执行下列操作：

a. 作为实例所有者登录。

b. 对每个数据库发出以下命令：

   db2updv9 -d dbname  

其中 dbname 表示数据库的名称。

4. 重新启动实例和 DAS。

如果安装了修订包来更新现有安装，则必须执行此步骤。如果安装了修订包来创建新安装，则不需要执行此步骤。

要重新启动实例：

a. 作为实例所有者登录。

b. 发出命令 db2start。

对每个实例重复上述步骤。

要重新启动管理服务器，作为 DAS 所有者登录并运行 db2admin start 命令。

5. 对绑定文件进行绑定

6. 可选：重新编译应用程序。

要在应用程序中利用对链接至的文件所作的任何更改，建议您重新编译该应用程序。

11. Tuning IBM HTTP Server to maximize the number of client connections to WebSphere Application Server
Out of the box, IBM HTTP Server supports a maximum of 600 concurrent connections. Performance will suffer if load dictates more concurrent connections, as incoming requests will be queued up by the host operating system. You can increase the number of maximum connections allowed by IBM HTTP Server by editing the httpd.conf file.

12. Intermittent delay returning response to a client request when ServerIOTimeout is set to non-zero value
When customer uses a non-zero value for the ServerIOTimeout option, responses to client requests are intermittently taking an excessive amout of time to be returned to the client. In fact the responses are being returned when the ServerIOTimeout value pops.
