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。

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。

Informix安装全攻略

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安装步骤

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。

一、安装前的准备:
以root用户身份登录系统后,
1、配置IP地址和Hostname。
2、建立空间大于150MB的Informix文件系统:
# smit crjfs
Mount Point:/informix
3、建立Informix组。
4、建立Informix用户:
primary group:informix
group set:informix,system
HOME directory:/informix
5、将异步IO激活:
# mkdev –l aio
# smit aio使异步IO在系统启动时自动available。
6、插入Informix按照媒体,键入:
# mount /Informix
# cd /informix
# tar –xvf /dev/rmt0 或 # cpio –icvBmud < /dev/cd0
7、更改环境变量:
# export INformIXDIR=/informix
8、创建LV(放置rootdbs):
# smit lv
Lvname:worklv
Devicename:rworklv
Size:80MB(最大2GB)
Type:raw
Mirror Write Consistency:no
Enable BAD BLOCK relocation:no
通常不建议将数据库的日志放在rootdbs上,而应单独建立一个raw类型的LV,存放logdbs。
用户的数据(如索引、表等)需存放在其他的raw类型的LV上。
9、更改LV的权限和属主:
# chown informix:informix rworklv
# chown informix:informix worklv
#chmod 660 rworklv
#chmod 660 worlv
10、更改Informix的环境变量:
# vi $HOME/.profile
export INformIXDIR=/informix
export TERMCAP=/informix/etc/termcap
export INformIXSERVER=ssc
export ONCONFIG=onconfig.ssc# informix启动时的配置文件
export TERM=vt100
11、分配Informix的端口号:
# vi /etc/services
info_service6666/tcp(Informix的端口名称端口号/tcp)
二、Informix的安装:
# cd /informix
# ./installsqlrt安装SQL SERVER
# ./installserver安装IDS SERVER
注意安装顺序:先装SQL Server,再装IDS Server,之后装4GL或Language Supp zh_CN。
不要一次将所有的安装文件一次拷贝至informix目录下,应拷贝一个安装一个。
# vi $INformIXDIR/etc/sqlhosts
ssconsoctcpdemo140info_service
(Informix服务器名称Informix的连接方式主机名Informix的端口名称)
三、Informix的配置:
1、以informix用户身份登录。
2、执行# onmonitor
选择Parameter菜单下的Initialiaze:
第一屏需修改的参数为:
Tape dev:/dev/null
Log Tape dev:/dev/null
Primary Path:/dev/rworklv
Phy. Log Size:4000
按ESC键提交。
第二屏需修改的参数为:
Server name:ssc
第三屏需修改的参数为:
Net type:soctcp210CPU
其余的参数均可使用缺省值。
完成后的正确信息应为Quiescent,错误信息为OFF-LINE。
选择EXIT,MODE,ONLINE,STARTUP,若显示ON-LINE信息,则安装成功。
若显示“Unable to attach to shared memoy”信息,则需重新校验上述步骤。
四、相关的命令:
# oninit启动Online系统
# onmode –ky关闭Online系统
# oncheck –pe查看Online系统中数据库的详细信息
# onstat –a查看所有的Online系统信息。
