$cd
$vi .bash_profile (在末尾添加以下内容)
exportLANG=zh_CN.GB2312
exportPATH
unsetUSERNAME
exportINFORMIXDIR=/bank/informix #informix的安装路径
exportPATH=$PATH:$INFORMIXDIR/bin
exportINFORMIXSERVER=cmsserver #要创建的database server名称
exportONCONFIG=onconfig.cmsserver #这个为配置文件,在etc目录下
exportDBDATE=y4md;
C. 新建etc/onconfig.cmsserver文件，根据$INFORMIXDIR/etc/onconfig.std模板进行，内容如下：
$cd
$cd etc
$cp onconfig.std onconfig.cmsserver
$vi onconfig.cmsserver

# 1 : notify DBA to add new logical logs when necessary. (ON)
# 0 : cannot add logical log on the fly. (OFF)
# When dynamic logging is on, we can have higher values for LTXHWM/LTXEHWM,
# because the server can add new logical logs during long transaction rollback.
# However, to limit the number of new logical logs being added, LTXHWM/LTXEHWM
# can be set to smaller values.
#
# If dynamic logging is off, LTXHWM/LTXEHWM need to be set to smaller values
# to avoid long transaction rollback hanging the server due to lack of logical
# log space, i.e. 50/60 or lower.
#
# In case of system configured with CDR, the difference between LTXHWM and
# LTXEHWM should be atleast 30% so that we could minimize log overrun issue.

注意以上红色部分，修改正确的informix安装路径，并在$INFORMIXDIR目录下新建data、log两个目录
D. touch数据库空间文件，并注意修改为660模式
$cd
$mkdir data
$mkdir log
$cd data
$touch rootdbs
$chmod 660 rootdbs
$cd ../tmp
$touch tmpdbs
$chmod 660 tmpdbs
E. 新建etc/sqlhosts文件，根据sqlhosts.std模板进行修改，内容如下：
cmsserver onsoctcp LinuxAsima cms_svc
其中cms_svc需要在/etc/services中定义
# Local services
cms_svc 8888/tcp
1.4 Informix初始化
A. 使用informix登录
B. 执行onmonitor
$onmonitor
