Informix数据库配置详细解说-电脑资料

Informix数据库配置详细解说-电脑资料1．配置概述本次数据库配置将采用数据库系统、数据库日志和数据库应用系统数据分开进行配置，以达到数据库系统优化的目的，。

2．营销系统数据库配置示例2.1 规划数据库空间根据配置的思想，将数据库系统分三个区。

分别是：rootdbs:informix系统区，我们将一号机的e1_1dbs4分配给它，为了便于记忆我们将该区取个名为yxroot。

具体操作为：#ln/dev/re1_1dbs4/dev/yx_root#chowninformix:informix/dev/yx_root#chmod664/dev/yx_rootlogdbs:informix日志区，我们将一号机的e1_1dbs5分配给它，为了便于记忆我们将该区取个别名为yx_log。

具体操作为：#ln/dev/re1_1dbs5/dev/yx_loG#chowninformix:informix/dev/yx_loG#chmod664/dev/yx_logworkdbs:informix数据区，我们将一号机的e1_1dbs0到e1_1dbs3分配给它，为了便于记忆我们将该区取个别名为yx_work。

具体操作为：#ln/dev/re1_1dbs0/dev/yx_dbs0#ln/dev/re1_1dbs1/dev/yx_dbs1#chowninformix:informix/dev/yx_dbs?#chmod664/dev/yx_dbs?2.2 Informix系统参数配置informix系统参数配置文件由如下文件决定：2.2.1 Informix启动环境文件：start_yx 文件内容如下：echo"startdbserveronyx"INFORMIXDIR=/usr/informix exportINFORMIXDIRTBCONFIG=tbconfig.yxDBDATE=Y4MD/PATH=$PATH:$INFORMIXDIR/bin:. exportPATHMAILTBCONFIG2.2.2 Informix配置文件：$INFORMIXDIR/etc/tbconfig.yx $cd$INFORMIXDIR/etc$cptbconfig.stdtbconfig.yx$vitbconfig.yx修改相应参数:ROOTPATH /dev/yx_rootROOTSIZE 1000000TAPEDEV /dev/nullPHYSFILE 100000LOGSIZE 100000LOGFILES 3LOGSIZE 100000MSGPATH /usr/informix/online_yx.loG CONSOLE /dev/consoleSERVERNUM 0DBSERVERNAME XXclic_yx#注:XX:按各地市名称来取#福州:fz 莆田:pt 泉州:qz 漳州:zz 龙岩:ly#三明:sm 南平:np 宁德:ndUSERS 300TRANSACTIONS 300LOCKS 200000BUFFERS 20000TBLSPACES 6000LOGSMAX 602.2.3 Informix网络连接配置文件：$INFORMIXDIR/etc/sqlhosts.yx该文件只有在C/S模式下和数据库联网才用到(略)2.3 Informix初始化操作：1．启动系统环境：以informix用户登录启动环境操作：#../start_yx2．初始化数据库系统区操作：tbinit-i3．创建数据库日志和工作区tbspaces–c–dyx_log–p/dev/yx_log–o0 –s870000tbspaces–c–dyx_work–p/dev/yx_dbs0 -o0 –s2000000tbspaces–ayx_work–p/dev/yx_dbs1 -o0–s20000004．移动数据库系统区的日志到新的数据库日志区a.在logdbs上生成逻辑日志，逻辑日志共取600M，每个日志100M，分6个。

Informix7.0安装及初始配置

Informix7.0安装及初始配置作者：出处：Unix爱好者家园更新时间：2004年09月26日1.建立informix用户建立informix用户，其用户组为informix，用户目录可设为 /usr/Informix大体来说informix数据库的安装步骤如下：2.设置环境变量Informix必须的环境变量如上所示。

一般来说，所有环境变量在.profile文件中设置。

以下例子中假定DBSERVERNAME 为online：在/.profile 、/etc/profile、/usr/informix/.profile中设置以下变量：INFORMIXDIR=/usr/informixINFORMIXSERVER=onlineTERM=ansiPATH=$PATH:/usr/informix/binexport INFORMIXDIR INFORMIXSERVER TERM PATH3.安装盘挂载将Informix安装盘挂载到系统中命令为mount /dev/cd0 /mnt （以超级用户root执行此命令）4.安装产品4.1安装INFORMXI--SQL将informix安装盘挂载到/mnt目录下以后，依次执行以下命令进行安装：cd /usr/informix当出现下面的提示时, 按回车键继续进行安装：之后系统要求输入INFORMIX-SQL产品的序列号和活动码：安装程序设置完系统文件的权限并对相关文件进行初始化完毕后, 结束INFORMIX-SQL系统的安装工作。

4.2 安装INFORMIX-ONLINE文件拷贝完毕后, 在#号提示符后面输入下面的命令, 执行INFORMIX-ONLINE系统的安装程序：当出现下面的提示时, 按回车键继续进行安装：之后系统要求输入INFORMIX-ONLINE产品的序列号和活动码:安装程序设置完系统文件的权限并对相关文件进行初始化完毕后, 结束INFORMIX-ONLINE系统的安装工作。

informix安装与配置

经常在论坛中看到有新人寻求informix的安装步骤，回想自己当初刚接触时，也是得到了众多好心人的帮助。

如今将自己的实际经验与从前前辈们的安装文档自整理下放到这里，希望能对有需要的人有所帮助。

由于毕竟经验有限，其中难免有遗漏或者不足的地方，欢迎大家批评指正！1. 创建informix组和informix用户，组ID和用户ID为301（注：此处可根据需要自己设置），并为informix用户设置密码group:informixuser:informix2. 为Informix数据库安装创建文件系统，并赋予权限，例：/informixchown -R informix:informix /informix3. 修改环境变量.profile文件INFORMIXDIR=/informix;PA TH=$PA TH:$INFORMIXDIR/bin;ONCONFIG=onconfig.test;INFORMIXSERVER=online;TERMCAP＝$INFORMIXDIR/etc/termcap;TERM=vt100;export INFORMIXDIR PA TH ONCONFIG INFORMIXSERVER TERMCAP TERM4. 数据库安装必须用root用户安装安装目录选择informix./ids_install（此为10版本的集成安装，显示如下：Product Setup Type------------------------------------------------ ------------------------1. [ ] IBM Informix IConnect2. [x] IBM Informix Client-SDK Typical3. [x] IBM Informix Dynamic Server Typical4. [x] IBM Informix JDBC Driver）若为10以下的版本，可以选择进入SERVER文件夹，执行installserver进行安装。

INFORMIX数据库系统安装手册

INFORMIX数据库系统安装⼿册参考地址：⼀起学习⼀、 INFORMIX数据库系统的组成我们公司在开发推⼴应⽤软件时, 选⽤INFORMIX-ONLINE和INFORMIX-SQL为数据库系统的开发、使⽤和维护平台。

其中INFORMIX-ONLINE共有7张3.5英⼨的软盘, INFORMIX-SQL共有4张3.5英⼨的软盘, 均为cpio的⽂件格式。

⼆、INFORMIX数据库系统的安装1. 建⽴INFORMIX数据库系统⽤户在安装INFORMIX数据库系统前, 应先建⽴INFORMIX数据库系统的⽤户, 其⽤户名为informix, ⽤户组为informix。

Informix⽤户的建⽴步骤如下：1）以超级⽤户root注册；2）输⼊如下命令： #sysadmsh 3)⼀次选择如下菜单： Accounts—User—Create4)系统出现输⼊画⾯时，依此输⼊(或选择)如下内容： Username 后输⼊：informix Comment 后不输⼊ Modify defaults?　选择yes　5)系统出现另⼀个画⾯是，依此输⼊(或选择)如下内容： Login group　时选择Specify 后输⼊：informix 如果系统中没有informix⽤户组，系统会提⽰： Do you wish to create it?: 选择 yes Group ID: 选择 Default 系统出现⼀个提⽰框，⾥⾯有两个⽤户组：group 和informix 将光标停在group上⾯，输⼊⼀个空格，再打回车。

Login shell　选择：Default Home directory　选择：Default、Create home User ID number　选择：Default Type of user 选择：Default 6)系统提⽰： Are you sure you wish to create this new user account? Please choose one of: 选择：Yes7)当系统提⽰： Press to continue:时，输⼊回车键。

Informix安装步骤

Informix安装步骤./ids_install —javahome /usr/bin/java1.前言本文主要描述的是在linux环境下的informix的安装配置步骤，且本实例采用的Cook File作为Chunk文件。

2.安装前准备(release文件首先得解压IDS安装包之后在解压的目录中find . –name “ids_mach＊")2.1.确认Informix所需的系统补丁●通过查看$INFORMIXDIR/rel ease/en_us/0333目录下的●采用如下指令，查看本机是否安装了上面系统补丁rpm –qa | grep <rpm name>2.2.确认Informix所需的内核参数●查看文件＄INFORMIXDIR/rel ease/en_us/0333/ids_machine_notes_11。

50.txt,确认该平台下Informix所需的内核参数配置。

请参考如下步骤进行内核参数修改:➢以root的身份登录➢修改文件/etc/sysctl。

conf➢执行“sysctl –p”，使更改生效2.3.确认DISK剩余空间充足请确保磁盘剩余空间〉1G，由于本实例采用cook file作为chunk文件,所以建议至少大于2G的磁盘空间2.4.创建Informix用户及组➢以root用户执行如下指令，创建所需的user和group3.安装informix软件3.1.创建安装环境在/home/informix目录下创建install目录，并将informix的安装包放在其目录下3.2.解压安装包3.3.执行安装指令下面出现的是安装过程中需要选择的一些信息: ●是否选用图形界面安装●确认安装选项●确认继续执行安装●确认安装版本●确认接受使用许可协议并继续●确认安装目录继续●确认安装的产品并继续●确认是否进行角色分离Do you want to enabl e rol e separation for auditing procedures?[ ] 1 - Yes［X］ 2 — NoTo select an item enter its number，or 0 when you are finished：[0] If you enabl e rol e separation, you can assign existing groups of users to specific rol es.If you d o not enabl e rol e separation，the database server administrator performs all administration tasks.Press 1 for Next，2 for Previous，3 to Cancel or 4 to Redisplay ［1] 1●确认是否建立IDS示范数据库服务器实例并继续●确认安装信息并继续●开始安装●确认是否读安装文本并继续●确认成功安装rmix实例配置4.1.环境变量的设置➢su – Informix 切换至informix用户➢vi setenv1150 建立一个脚本写环境变量➢将脚本写到.bash_profil e中➢执行. ./。

AIX上安装Informix NBU 插件

如何安装NBU 的Informix 插件环境Aix 5.2.0，NBU 5.1（mp2）,Informix Dynamic Server Version 9.40.FC3，HostName MyAix,Informix server name: eMarket安装步骤一、使用root 用户登录二、执行命令确认是否安装了Informix 插件的有效licence：#/usr/openv/netbackup/bin/admincmd/get_license_key三、安装插件。

将NBU Option 安装盘插入驱动器，执行下列命令：#mount –v cdrfs /dev/cd0 /cdrom#cd /cdrom#./install系统将显示下列信息：NetBackup Database Agent InstallationChoose the Database Agents you wish to installone at a time or select Install All Database Agents.1) NetBackup for DB22) NetBackup for Informix……q) Done Selecting Agentsx) Exit from this ScriptSelect the Oracle option if upgrading any of thefollowing: Oracle, Oracle on UNIX Advanced BLI Agent,Oracle ServerFree Agent or Database Archiver.The packages have been combined.Choose an option: 2Choose an option: qYou have chosen to install these Database Agents:NetBackup for InformixIs this list correct? [y,n] (y)选择y 后系统开始安装Informix 插件：Installing NetBackup for InformixInstalling NetBackup for Informix...Extracting files from /usr/openv/netbackup/dbext/INFORMIX.rs6000_51.tar.Z ...……NetBackup for Informix installation completed.**********Execution of ./install_dbext is complete.Execution of ./install is complete.File /tmp/install_options_trace.23880 contains a trace of this install.四、设置informix home 路径。

安装INFORMIX数据库(AIX)
part1 安装前准备
rmix 11.10 for aix 32bit
2.IIF_11.10.UC2W4_AIX_pSeries_32_IFix.tar（此补丁为解决xlc版本问题）
3.AIX5.3操作系统安装盘（安装C编译器所需系统包）
4.IBM C编译器（Version 9.0）
part2 安装informix数据库
一、建立informix组和informix用户
1.建立informix组（组ID设为大于200）
2建立informix用户
3、给informix用户设置密码
1、将各安装包拷贝到/home/informix下
2、配置informix用户的环境变量
3、配置文件如下
4、设置INFORMIXDIR
三、开始安装数据库组件
1、安装isql
1）解压SQL.TAR
2）执行installsql开始安装isql
3）7.3版输入序列号
4）执行安装isql，直至显示安装完成。

2、安装ESQRT
1）解压esqrt.tar
2)运行./installesqrt执行安装
3）碰到提示RETURN回车下一步，直到显示安装完成。

3.安装esql
1）解压esql.tar
2)执行./installesql
3)碰到RETURN回车直到显示安装完成
4.安装IDS服务器
1）解压IIF_11.10.UC2W4_AIX_pSeries_32_IFix.tar
2)执行./installserver开始安装ids服务器
3）自动转入安装向导，一路回车
安装在默认路径/home/informix
ids服务器安装完成。

3、安装ids其他组件CSDK和JDBC 1）解压informix32.tar
2）执行./ids_install开始安装
3）安装程序自动转入安装向导
4）在选择安装组件的时候把IDS选项取消，如图执行(前面已经安装IDS11.10)
至此informix所有组件安装完成。

part3 配置informix数据库
1、建立名为chunk00的lv，类型为裸设备，大小为2个G。

注：这里一个PP为512M，所以设为4个PP
回车运行创建chunk00成功
2、建立异步通信aio（需要重启服务器）
3、编辑/etc/hosts文件
4、编辑/etc/services文件
5、切换为informix用户进入etc文件夹
复制onconfig.std为onconfig.btp（.profile中指定的配置文件）
6、配置/home/informix/etc下sqlhosts文件
7、运行onmonitor进行系统初始化
1）选择Parameters
2)选择Initalize
3)进入参数配置界面（这里所用参数为旧测试服务器上数据，需要根据新服务器配置进行修改）
4）初始化最后确定
5）经过一系列的初始化过程
6)数据库初始化完毕，进入online模式
7）数据库安装配置完成
8）用onstat查看数据库运行状态
informix数据库安装配置完成。

part5 安装C编译器
