空间为1G。
2、chown -R informix:informix informixMount /Informix 激活文件系统3、用smitty建立informix用户，令informix用户的主目录为/usr/informix。
4、编辑/usr/informix目录下的.profile文件写入脚本。

◆三个节点配置的CM启用了负载均衡，如下：
11:41:35 SLA qxgl redirect SQLI client from 10.19.65.139 to rmsdb_sds 10.19.65.164.9977
11:41:36 SLA qxgl redirect SQLI client from 10.19.65.139 to rmsdb_sds 10.19.65.164.9977
11:51:16 SLA qxgl redirect SQLI client from 10.19.65.139 to rmsdb_sds 10.19.65.164.9977
可见SLA qxgl分配到了不同的数据库server，实现了负载均衡的效果。再看刚才的log：

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/release/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?

Informix安装配置精讲
Informix-online Dynamic server完全安装手册一、安装步骤：（1）创建informix目录：/informix如果已创建，这一步可以不执行。
（2）创建informix用户及informix组。
（3）设置环境变量。
设置环境变量在profile文件增加以下内容：INFORMIXDIR=/usr/InformixINFORMIXSERVER=pthkONCONFIG=onconfig.pthkPATH=$PATH：$INFORMIXDIR/binexport INFORMIXDIR INFORMIXSERVERexport ONCONFIG PA TH说明：INFORMIXSERVER 该环境变量被设置为服务器的名称，它是客户机与服务器进行连接的入口，它的值将放入sqlhosts文件中，只有该值有效时客户才能完成与服务器的连接（如果客户与服务器的机型不同，则需要将sqlhosts文件同时装入所有的机器中，以便进行初始化操作）。
(4)SQL 和 online的安装以 root 用户注册, 进入 informix 用户目录:# cd /usr/informix执行命令:# . ./.profile使informix 环境变量生效;SQLRT.TAR、CONNECT.CPI 、IDS.CPI将SQL的安装文件拷贝到当前目录下:用 tar 或 cpio 命令(根据安装文件类型而定);#tar xvf (文件名.TAR)#cpio –icudvmB –I (文件名.cpi)执行SQL的安装程序:# ./installsql根据屏幕提示输入正确的序列号 (serial number) 和活动码 (active number);完成SQL的安装;#./installconn第一个选yes第二个选no将 online 的安装文件拷贝到当前目录下:用 tar 或cpio 命令(根据安装文件类型而定); 将安装文件展开;执行 online 的安装程序:# ./installserver根据屏幕提示输入正确的序列号 (serial number) 和活动码 (active number);完成 online 的文件安装(5) 修改sqlhosts文件中的通信参数。

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。
5. 为informix实例创建裸设备，可根据需要自行添加。
例：裸设备名称分别为：testroot，testdata01，testdata02，testphy，testtmp，testindex，testlog 为裸设备修改属主和权限chown informix:informix /dev/test*chown informix:informix /dev/rtest*chmod 660 /dev/test*chmod 660 /dev/rtest*6. 为裸设备创建链接文件su – informixcd /informixmkdir data************************ln –s /dev/rtestroot testrootln –s /dev/rtestindex testindexln –s /dev/rtestphy testphyln –s /dev/rtestlog testlogln –s /dev/rtesttmp testtmpln –s /dev/rtestdata01 testdata01ln –s /dev/rtestdata02 testdata02****************************7.修改onconfig和sqlhosts文件cp onconfig.std onconfig.testvi onconfig必须修改的参数如下：ROOTNAME rootdbs # Root dbspace nameROOTPA TH /informix/data/testroot # Path for device containing root dbspace ROOTOFFSET 0 # Offset of root dbspace into device (Kbytes)ROOTSIZE 2000000 # Size of root dbspace (Kbytes)MSGPA TH /informix/online.logSERVERNUM 0 # Unique id corresponding to a Dynamic Server instance DBSERVERNAME online # Name of default database serverTAPEDEV /informix/data/backLTAPEDEV /informix/data/backup如果不需要将逻辑日志备份存放到磁盘上，可以设置成为LTAPEDEV /dev/nullNETTYPE ipcshm,1,100,CPUDBSERVERNAME online # Name of default database serverCLEANERS 8 # Number of buffer cleaner processesSHMVIRTSIZE 81920 # initial virtual shared memory segment sizeSHMADD 16384 # Size of new shared memory segments (Kbytes) BUFFERPOOL size=4K,buffers=500000,lrus=8,lru_min_dirty=50.000000,lru_max_dirty= 60.000000#其它参数可根据需要进行设置。
如果逻辑日志备份到NULL，需要更改以下参数为：ALARMPROGRAM /informix/etc/log_full.sh # Alarm program path默认目录是的/usr/informix改成/informix在/informix/etc/services下填加online testport 50001/tcp（此端口号请根据需要自行添加，不可与其他已有端口冲突。
）vi sqlhosts#demo_se seipcpip se_hostname sqlexeconline onsoctcp testhost testport各段含义依次是：DBSERVERNAME（数据库服务器名在onconfig文件中引用）NETTYPE（格式为ddiiippp，dd段为on或ol；iii段为网络接口，取值ipc为进程间通信、soc为插槽；ppp段为shm：共享内存连接、tcp为网络连接中的TCP/IP协议、str为流管道、nmp为命名管道、spx为网络连接中的IPX/SPX协议）HOSTNAME（或IP address）：定义包含informix实例的计算机SERVICE NAME：使用的服务，这个服务在系统的服务文件中定义（UNIX中为/etc/services）9. $oninit –ivy初始化，并创建各DBspace。
开启大块功能：（注：9.4以上版本不再受每个CHUNK不得超过2G空间的限制，需要开启大块功能支持。
）$onmode -BC 1$onspaces –c –d phydbs –p /informix/data/testphy –s 1000000 –o 0$onmode -s$onparams –p –s 950000 –d phydbs –y$ontape –s –L 06.逻辑日志移到自dbspace中估计逻辑日志数量及大小，确定逻辑日志空间大小，例：50M*18=900M$onspaces –c –d logdbs –p /informix/data/testlog –s 1000000 –o 0$onmode –s$onparams –a –d logdbs –s 50000此命令反复执行18次，填加18个新日志。
移动当前日志指针$onmode –l反复执行该命令用以将新添加的逻辑日志激活。
onstat -l查看初始逻辑日志numberonparams –d –l 1 删除number为1的逻辑日志，改变number可将所有系统自动创建的逻辑日志文件删除。
做日志校验$onmode –c 用于将当前日志与校验点位置达到一致。
10.生成tempdbs indexdbs datadbs$onspaces –c –d tempdbs –t –p /informix/data/testtmp –s 2000000 –o 0$onspaces –c –d indexdbs –p /informix/data/testindex –s 2000000 –o 0$onspaces –c –d datadbs –p /informix/data/testdata01 –s 5000000 –o 0$onspaces –a –d datadbs –p /informix/data/testdata02 –s 5000000 –o 0informixonline的安装在Unix下安装Informix Online具有一定的难度，下面把安装的主要步骤和需要注意的问题介绍给大家。
一、磁盘空间的准备Online使用的Database所建立的磁盘空间有两种,一种是Cookied File,另一种是Raw Device。
安装Online之前,首先要确定Dbspace在哪种Chunk上,即使用的是Cookied File还是Raw Device。
Cookied文件是Unix的文件,通常可用下列方法建立:1.Cat/dev/null>file－name2.Chmod 660 file－name3.Chgrp informix file－name4.Chown informix file－name以上方法虽然有Dbspace随数据量增加而增加的优点，但由于受Unix系统对文件管理层的约束,所以效率比较低,建议大家尽量不要采用。
通常采用的方式是Raw Device,也称“裸设备”，就是在安装Unix磁盘时，用divvy命令在磁盘分区中建立一块Non FS分区，对此分区的大小预先要估算好。
Online系统对“裸设备”的管理比Unix文件系统的管理效率高很多。
二、Unix系统核心参数的修改由于Online需要Unix系统有关方面的开销比系统默认的要大,所以要调整部分Unix系统的核心参数。
通常调整以下参数:信号量参数SEMMNI SEMMSL SEMMNS共享内存参数SHMMAX SHMSEG SHMMNI文件及进程参数NFILE NPROC其中共享内存参数SHMMAX的值不能大于物理内存,通常为1/4物理内存,也可根据具体情况来确定。
其他的参数值可适当增大成原来的2倍,也可根据情况来定。
