因生产需要,网站空间,在一台IBM X3850服务器上安装DB2数据库,香港空间,下面是具体过程。
软硬件系统配置:
操作系统:suse enterprise 10 linux(64bit) sp3
硬件配置:32G内存
数据库软件:DB2 V9.7(64bit)
一、检查所需的环境和软件包
在 suse Linux 操作系统上安装DB2数据库之前,应确保系统满足必需的操作系统、硬件、软件和通信要求。
DB2数据库产品有若干不同版本。某些DB2数据库产品和功能部件仅在特定操作系统上可用。这个可参阅IBM官方网站来获取每个操作系统上可用的 DB2 数据库产品。
先用rpm -qa查找所需的软件包,没有的包可用yast2 -i来安装。
linux-uu1q:# rpm -qa|grep libaio
libaio-0.3.104-14.2
libaio-devel-0.3.104-14.2
linux-uu1q:# rpm -qa|grep libstdc
libstdc++-devel-4.1.2_20070115-0.29.6
libstdc++-4.1.2_20070115-0.29.6
linux-uu1q:# rpm -qa|grep nfs-utils
nfs-utils-1.0.7-36.36.47
linux-uu1q:/home/server # rpm -qa |grep compat-libstdc
compat-libstdc++-33-3.2.3-61
(检查是否有libstdc++.so.5
linux-uu1q:/usr/lib64 # ls -l libstdc++.so.*
lrwxrwxrwx 1 root root 18 Feb 22 03:34 libstdc++.so.5 -> libstdc++.so.5.0.7
-rwxr-xr-x 1 root root 825400 Apr 9 2007 libstdc++.so.5.0.7
lrwxrwxrwx 1 root root 18 Feb 21 21:57 libstdc++.so.6 -> libstdc++.so.6.0.8
-rwxr-xr-x 1 root root 969048 Sep 5 2009 libstdc++.so.6.0.8)
注意这个compat-libstdc++-33-3.2.3-61.x86_64.rpm的包在SUSE LINUX 10的光盘里并没有,需要自己下载并安装,另外如果没有安装这个包,则在安装DB2时会报找不到libstdc++.so.5的告警。(对于 DB2 数据库服务器和客户机,网站空间,libstdc++.so.5 是必需的。还有如果你在 RHEL 5 或 SLES 10 上使用 g++ 4.1 来编译 C++ 应用程序,那么将生成下列警告:libdb2.so 所需要的 libstdc++.so.5 可能与 libstdc++.so.6 冲突)
修改系统核心参数
vi /etc/sysctl.conf
kernel.msgmni = 16384
kernel.sem = 250 256000 32 4096
#sysctl -p
#vi /etc/security/limits.conf
* soft nofile 10240
二、开始进行安装和配置
# tar -xvf DB2v9.7_linux64_server.tar
# cd server
# ./db2setup (或也可使用db2_install)
安装到默认路径/opt/ibm/db2/V9.7下面,安装类型选择ESE
最后一步一步安装下去,直至完成。
三、添加用户和组
#groupadd -g 995 db2grp
#useradd -u 1000 -d /home/db2inst1 -g db2grp -m db2inst1
#groupadd -g 996 db2fgrp
#useradd -u 1001 -d /home/db2fenc1 -g db2fgrp -m db2fenc1
的组)
-m dasusr1
# passwd db2inst1
# passwd db2fenc1
# passwd dasusr1
四、在安装目录中找到许可证文件:db2ese.lic
检查license的内容
$db2licm -l
执行如下安装授权许可
#/opt/ibm/db2/V9.7/adm/db2licm -a /mnt/cdrom/db2/license/db2ese.lic
# cd /opt/ibm/db2/v9.7
# ls -l
#cd instance
# ./db2icrt -s ese -u db2fenc1 db2inst1 (建立数据库实例)
# ./dascrt -u dasusr1 (建立das)
#cd /opt/ibm/db2/V9.7/cfg
# ./db2ln ()
六、设定服务端口,配置数据库实例通信
以root用户
vi /etc/services
新增如下行
DB2_db2inst1 60000/tcp
DB2_db2inst1_1 60001/tcp
DB2_db2inst1_2 60002/tcp
DB2_db2inst1_END 60003/tcp
DB2c_db2inst1 60005/tcp
保存退出
七、启动实例
#su - db2inst1
$db2set DB2RSHCMD=/usr/bin/ssh
这里需要先设置DB2RSHCMD这个变量,再设置DB2COMM等变量
)
)
$db2set DB2AUTOSTART=YES(设置数据库自动启动)
$ db2start
02/22/2013 01:40:54 0 0 SQL1063N DB2START processing was successful.
SQL1063N DB2START processing was successful.
(创建数据库之前需要指定数据库存放目录并配置相应的权限
#mkdir -p /db2data/database
# chown -R db2inst1:db2grp /db2data/database)
创建数据库
$db2 "CREATE DATABASE testdb on /db2data/database USING CODESET GBK TERRITORY CN"
$db2 connect to testdb
注意在连接数据库时,如果报下述错误
SQL0332N Character conversion from the source code page "1386" to the target

There are many questions that Linux beginners often ask, "Does Linux have a Task Manager?", "How to open the Task Manager on Linux?" Users from Windows know that the Task Manager is very useful. You can open the Task Manager by pressing Ctrl+Alt+Del in Windows. This task manager shows you all the running processes and the memory they consume, and you can select and kill a process from the task manager program. When you first use Linux, you will also look for something that is equivalent to a task manager in Linux. A Linux expert prefers to use the command line to find processes, memory consumption, etc., but you don't have to

Zabbix's support for Chinese is not very good, but sometimes we still choose Chinese for management purposes. In the web interface monitored by Zabbix, the Chinese under the graphic icon will display small squares. This is incorrect and requires downloading fonts. For example, "Microsoft Yahei", "Microsoft Yahei.ttf" is named "msyh.ttf", upload the downloaded font to /zabbix/fonts/fonts and modify the two characters in the /zabbix/include/defines.inc.php file at define('ZBX_GRAPH_FONT_NAME','DejaVuSans');define('ZBX_FONT_NAME'

Did you know, how to check the creation date of an account on a Linux system? If you know, what can you do? Did you succeed? If yes, how to do it? Basically Linux systems don't track this information, so what are the alternative ways to get this information? You may ask why am I checking this? Yes, there are situations where you may need to review this information and it will be helpful to you at that time. You can use the following 7 methods to verify. Use /var/log/secure Use aureport tool Use .bash_logout Use chage command Use useradd command Use passwd command Use last command Method 1: Use /var/l

System-wide installation If you install a font system-wide, it will be available to all users. The best way to do this is to use RPM packages from the official software repositories. Before starting, open the "Software" tool in Fedora Workstation, or other tools using the official repository. Select the "Add-ons" category in the selection bar. Then select "Fonts" within the category. You'll see the available fonts similar to the ones in the screenshot below: When you select a font, some details will appear. Depending on several scenarios, you may be able to preview some sample text for the font. Click the "Install" button to add it to your system. Depending on system speed and network bandwidth, this process may take some time to complete

1. Find the fonts wingdings, wingdings2, wingdings3, Webdings, and MTExtra from the Internet. 2. Enter the main folder, press Ctrl+h (show hidden files), and check if there is a .fonts folder. If not, create one. 3. Copy the downloaded fonts such as wingdings, wingdings2, wingdings3, Webdings, and MTExtra to the .fonts folder in the main folder. Then start wps to see if there is still a "System missing font..." reminder dialog box. If not, just Success! Notes: wingdings, wingdin

How to use one network cable to connect two ubuntu hosts to the Internet 1. Prepare host A: ubuntu16.04 and host B: ubuntu16.042. Host A has two network cards, one is connected to the external network and the other is connected to host B. Use the iwconfig command to view all network cards on the host. As shown above, the network cards on the author's A host (laptop) are: wlp2s0: This is a wireless network card. enp1s0: Wired network card, the network card connected to host B. The rest has nothing to do with us, no need to care. 3. Configure the static IP of A. Edit the file #vim/etc/network/interfaces to configure a static IP address for interface enp1s0, as shown below (where #==========

Different CPU architectures mean that running DOS on the Raspberry Pi is not easy, but it is not much trouble. FreeDOS may be familiar to everyone. It is a complete, free and well-compatible operating system for DOS. It can run some older DOS games or commercial software, and can also develop embedded applications. As long as the program can run on MS-DOS, it can run on FreeDOS. As the initiator and project coordinator of FreeDOS, many users will ask me questions as an insider. The question I get asked most often is: "Can FreeDOS run on a Raspberry Pi?" This question is not surprising. After all, Linux runs very well on the Raspberry Pi
