数据库：db2 V9.7（64bit）
2.基础准备
操作系统，可在下述地址下载：

SLES-11-SP3-DVD-x86_64-GM-DVD1.iso

数据库，可在下述地址下载：

3.安装步骤
3.1.安装包上传解压
将上述下载的DB2解压至/home/software：tar -xvf v9.7fp6_linuxx64_server.tar.gz
3.2.安装前检查
进入解压后的目录，执行下述命令：/home/software/sever/db2prereqcheck
3.2.1.一般常见问题
3.2.1.1.问题一

这个是说开启了内存地址随机化机制（address space layout randomization)功能，这个功能对DB2本身没有太大影响，有个别工具db2pd db2egcf 会出现异常，若有强迫症，如下：

官方解释：
DBT3534W
db2prereqcheck实用程序确定ASLR设置为ON并且这可能导致某些工具发生问题。

说明
地址空间布局随机化(ASLR)缺省情况下在某些Linux分发上已激活。ASLR被设计为在随机地址装入共享内存对象。
ASLR启用后，DB2数据库不能保证地址对共享内存对象可用。
地址空间中的此冲突意味着尝试将共享内存对象附加至特定地址的进程可能无法完成任务，从而导致shmat子例程失败。但是，后续使用新进程重试共享内存附加时可能会成功。结果是一组随机失败。已知会见到此错误的一些进程包括：db2pd、db2egcf和db2vend。
此问题可能导致的一些错误包括以下各项：
db2pd命令可能会报告找不到数据，即使实例或数据库处于活动状态。
db2egcf进程（用于监视）可能会错误地确定实例已关闭并启动故障转移操作。
在备份和日志归档操作中，db2vend进程可能会失败，并产生错误，指示未能启动子进程。

用户响应
通过设置以下内核参数来关闭随机化：
kernel.randomize_va_space=0
通过发出以下命令来临时禁用随机化并重新启动DB2实例：
echo0>/proc/sys/kernel/randomize_va_space
或者
sysctl -w kernel.randomize_va_space=0

上面两条命令是临时更改，重启后，该值会还原成2
要想永远关闭，则编辑/etc/sysctl.conf文件
新增一行kernel.randomize_va_space=0
保存退出后，运行sysctl-p使之生效，重启后也有效了。
3.2.1.2.问题二

这个是DB2要求的一个32位的pam库

官网解释如下

参考IBM官方解决方案IC87092：
http://www-01.ibm.com/support/docview.wss?rs=0&q1=IC87092&uid=swg1IC87092&loc=zh_CN&cs=utf-8&lang=
大概意思就是说,DB2会找libpam.so文件，通常会找lipan.so.0，但可能涉及不定期更新，因此需要手工做个软链接到最新的文件
以下是具体操作：
安装PAM包（用zypper命令，具体用法可百度），到安装后生成的库文件
建立符号链接
[root@SUSE-Linux]#ln -s /lib/libpam.so.0.82.2 /lib/libpam.so

A minor error occurred while installing “DB2 Enterprise Server Edition ” on
this computer. Some features may not function correctly.

ESE 一共48个步骤，最后安装完成后，有个提示：说有个较小的错误发生了，可能会影响某些功能的正常使用，这个一般没问题
具体看日志如下

Post Install Recommendations

看到了吧，就是SA MP安装失败，那么这个鸟东西是做什么的呢？为什么会失败，失败后有什么影响呢？

还是看这个日志，刚刚看的是最后方，再看看开始的地方
Target directory: /opt/ibm/db2/V9.7

Space required: 1068 MB
Install SA MP: No

TSAMP_VERSION=3.2.2.1
DBI1130E The IBM Tivoli System Automation for Multiplatforms (SA MP)
could not be installed or updated because system prerequisites
were not met. See the log file /tmp/prereqSAM.log.17992 for details.

Explanation:

There are system prerequisites for installing or updating SA MP. These
prerequisites have not been met.

The mentioned log file has the details for the unsatisfied
prerequisites.

To find out more about the system prerequisites for the SA MP Base
Component, see the SA MP Base Component documentation’s Installation and
Configuration Guide.

SA MP cannot be installed or updated.

User response:

Modify your system to meet the prerequisites; and use the installSAM
utility to manually install SA MP.

哦，原来SA MP 是 IBM Tivoli System Automation for Multiplatforms 缩写，再看看后面的日志文件为啥失败
prereqSAM: OPTIONS = ‘-l /tmp/prereqSAM.log.17992 –noliccheck –silent’
prereqSAM: OPT_SILENT = 1
prereqSAM: OPT_NOLICCHECK = 1
prereqSAM: Detected operating system Linux
.
.
.
prereqSAM: Most severe error code returned 21
prereqSAM: Unable to perform prerequisite checking

恩，是说在检查SA MP安装的时候失败，返回错误码21：
好吧，到这个时候，应该找不到问题解决了吧，别急，再仔细看看日志 ，哦？有个错误号DBI1130E
大家注意，在好的软件遇到问题的时候，第一反应要知道两个内容，错误解释和错误编号，如果有的话

官方解释如下：
这个错误消息是有关Tivoli Systems Automation (TSA) 的，对DB2的核心功能一般情况下没有什么影响。
有一种情况会产生影响，就是当做HADR的时候（就是这个 High Availability features ），当其中1台机器失败时，不能自动路由跳转到另外一台机器继续提供DB服务。

这个也是仅仅在HADR使用TSA作为跳转。如果不试用TSA组件，那么这个错误完全可以忽略不计。

如果真的需要使用TSA功能。（或者有些人实在强迫症，看不得报错？）那么可以手动执行installSAM脚本安装这个（SA MP），具体请看：
Installing IBM Tivoli System Automation for Multiplatforms (SA MP) Base Component using the installSAM install script
这个链接叫：使用 installSAM 安装脚本来安装 IBM Tivoli System Automation for Multiplatforms (SA MP) Base Component ，这个就不继续往下了，Tivoli以后再说吧。

官方原文：
Technote (troubleshooting)

Problem(Abstract)
DB2 install fails with “DBI1130E The SA MP Base Component could not be installed or updated because system prerequisites were not met.” error message.
Symptom
While trying to install DB2 V9.5 and later, the error message DBI1130E might be returned. Additional log file /tmp/prereqSAM.log.123456 should be available for more details.
Cause
The DBI1130E error messages is returned when some of the pre-requisites needed for installing the particular component are missing or are not installed.
Environment
Note: This technote is true only for installations of DB2 Versions 9.5 and later that have the TSA component bundled with the install.
Diagnosing the problem
The error message from the install log should read as below:
DBI1130E The SA MP Base Component could not be installed or updated
because system prerequisites were not met. See the log file
/tmp/prereqSAM.log.454724 for details.

Explanation:
There are system prerequisites for installing or updating the IBM Tivoli
System Automation for Multiplatforms Base Component (SA MP Base
Component). These prerequisites have not been met.
The mentioned log file has the details for the unsatisfied
prerequisites.
To find out more about the system prerequisites for the SA MP Base
Component, see the Installation and Configuration Guide at
http://publib.boulder.ibm.com/tividd/td/IBMTivoliSystemAutomationforMultiplatforms2.2.html.
The SA MP Base Component cannot be installed or updated.

User response:
Modify your system to meet the prerequisites; and use the installSAM utility to manually install the SA MP Base Component.
The /tmp/prereqSAM.log.123456 might have some failures relating to AIX packages as below:
prereqSAM: Error: The following AIX package is not installed rsct.opt.storagerm
prereqSAM: Error: Prerequisite checking for the ITSAMP installation failed AIX 6100-04
prereqSAM: Most severe error code returned 21
prereqSAM: One or more prerequisite packages were not found installed

Note: The package name is not restricted to rsct.opt.storagerm. There might be other operating system packages mentioned in the error messages as well.

Resolving the problem
This DBI1130E error message is related to the Tivoli Systems Automation (TSA) and this is not a component that affects core DB2 functionality, as it deals with some of the more advanced High Availability features of DB2. In essence, it handles DB2’s fail-over from one machine to another. If the TSA component is not going to be used, the error message can be safely ignored.
If the need to use TSA arises in future, the installSAM script can be used to manually install the component. The following link can help:

Installing IBM Tivoli System Automation for Multiplatforms (SA MP) Base Component using the installSAM install script
To resolve this issue, install the reported operating system package mentioned in the prereqSAM.log.123456 file and re-run the installation.
