◆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安装全攻略

若有多个online,Message Log最好区分开来，如online_01.log
Dump Shared Memory改为N
(7)新建一个Dbቤተ መጻሕፍቲ ባይዱpace
onmonitor->Dbspaces->Create
名称、大小自定，Mirror、Temp都为N，路径/u1/cookfile/infx01
输入/opt/Informix 安装路径
若在安装过程中出现:
etc/brand: error while loading shared libraries: libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file or directory
o options
为指定连接提供额外的灵活性。
(5)编辑.profile文件
su - informix
vi .profile
添加内容如下：
INFORMIXDIR=/u1/informix;export INFORMIXDIR
INFORMIXSERVER=test_on;export INFORMIXSERVER
解决：
修改配置文件onconfig中的服务器标识号（默认为0），只要是唯一就可以了，不能过太。在多实例安装中常出现此问题。例如
SERVERNUM 49 # Unique id corresponding to a Dynamic Server instance
nettype最后三个字母按如下方式表示特定的IPC机制或通讯协议。
shm 共享内存通讯
str 数据流管道通讯

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。

windows+informix+环境搭建说明二、Informix数据库安装（windows）1、在IFMXDATA目录下生成文件：copy nul rootdbs_dat.0012、扩充数据库空间：onspaces -a rootdbs -o 0 -pC:\IFMXDATA\ol_ea001\rootdbs_dat.001 -s 1000000onspaces -a rootdbs -o 0 -p D:\IFMXDATA\ol_lyc\rootdbs_dat.001 -s 10000002.2、增加数据库日志空间：onparams -a -d rootdbs -s size3、设置字符集：修改Informix数据启动文件set CLIENT_LOCALE=EN_US.8859-1set DB_LOCALE=EN_US.8859-1set SERVER_LOCALE=EN_US.8859-1set DBDATE=Y4MD-4、导入备份数据库文件：dbimport databasename5、修改informix安装目录下\etc\ONCONFIG.***文件中的TAPEDEV \\.\tape0 # Tape device path 为TAPEDEV NUL # Tape device path(其中***为informix的server名称)原因：informix为Linux文件系统，在windows下就必须修改6、如果提示Mirror那么需要修改ONCONFIG.***文件中的Mirror配置部分为0，将路径清空7、设置数据库日志格式：ontape -s -U xxloan(用户数据库)这一句一定要执行，不然到时候会报：SQLException :transactions is not surported8、设置数据库临时表空间设备：DBSPACETEMP rootdbs # Default temp dbspaces9、查看数据库日志模式 onmonitor (UNIX环境下)10、如果报没有select view权限，那么需要修改数据库中的用户名"informix"---->"loan"安装informix for nt时报错日志报错信息：Thu Jan 12 08:14:38 200608:14:38 DR: DRAUTO is 0 (Off)08:14:43 Informix Dynamic Server Version 7.31.TC8 Software Serial Number AAB#A58518508:14:43 listener-thread: err = -25572: oserr = 0: errstr = : Network driver cannot bind a name to the port.08:14:43 Attempting to bring listener thread down.08:14:43 Server stopped.08:14:43 Informix Dynamic Server Stopped.08:14:47 mt_shm_remove: WARNING: may not have removedall/correct segments导入数据的时候是乱码去掉最后一行后还需要还一下cmd的属性-选项-当前代码页--选gbk在解决办法：修改注册表中informix下面的HKEY_LOCAL-MACHINE SOFTWARE INFORMIX SQLHOSTS修改service项，把他该为tcp端口号！HKEY_LOCAL_MACHINE\SOFTWARE\Informix\SQLHOSTS\ol_lychost 电脑名字service 电脑名字protocol olsoctcpSQL 状态 = 08004，错误代码 = -908 而失败。

Informix安装完成后进行配制

Informix安装完成后进行配制一、测试是否已经连接先点击开始→所有程序→Informix Clinet SDK→ILogin Demo如下图就会弹出一个测试是否联通了的测试界面如下点击File→Run就会弹出如下图然后在这个页面里输入相应的信息如下图里面的server里填写的是数据库服务名：enipas_online_net Hostname里填写的是数据库IP地址：221.5.135.13 Servicename里填写的是数据库端口：9003Protocolname里填写的是onsoctcpUsername 里填写的是用户名scutestPassword 里填写的是密码scutestStores Database 里填写的是数据库名：scpdb填写完后再点击OK进行测试如出现下面的窗口就是连接测试成功然后关闭这个重启电脑（informix客户端安装后一定要重启后才能使用）二、配制informix点击开始→所有程序→Informix Client SDK →Informix Setnet32 如下图就会弹出点击Server Information 如下图在这里填写完相应信息如下图在informix Server里填写数据库服务名：enipas_online_net HostName 里填写数据库IP地址：221.5.135.13 Protocolname里填写的是onsoctcpService Name里填写的是数据库端口：9003然后点击Host Information 就会弹出如下页面在这里填写数据库的用户名和密码如下图然后点击确定就会弹出如下信息点击确定就可以了三、配制informix的ODBC数据源重启后开始配制informix的ODBC数据源: 如下图1、点击开始→管理工具→数据源就会弹出下图2、就会出现下图点击添加就会出现下图选择INFORMIX 3.30 32 BIT就会出现下图在Data Source Name里输入连接名cqwtin7 然后点击Connetction在Connetction 里的Server Name里输入数据库服务名：enipas_online_net 然后再填写Database Name 里输入数据库名scpdb在User Id里输入用户名scutestPassword 里输入密码scutest然后点击Test Connection进行连接测试如果成功就可以了。
