九、配置informix
1，初始化配置
准备数据库server用onconfig文件和修改sqlhosts
n 以informix用户注册，进入$INFORMIXDIR/etc目录，执行cp onconfig.std onconfig.数据库server名，其中onconfig文件名和informix的.profile中的设置对应。
在此处执行命令：# cd /home/db/informix/etc
# cp onconfig.std onconfig.front
n 调整informix数据库配置参数
编辑onconfig.front，修改以下参数
ROOTSIZE rootdbs大小 500000
ROOTPATH /home/db/Informix/dbs/rootchunk0
PHYSFILE 100 MB
LOGFILES 3 # Number of logical log files
LOGSIZE 2000 # Logical log size (Kbytes)
SERVERNUM 0
NETTYPE soctcp,3,200,NET
MULTIPROCESSOR 1
NUMCPUVPS 3
LOCKS 3000000
BUFFERS 800000
NUMAIOVPS 8
PHYSBUFF 256
LOGBUFF 256
CLEANERS 16
SHMVIRTSIZE 384000
SHMADD 128000
TAPEDEV /dev/null
LTAPEDEV /dev/null
DBSERVERNAME front
MSGPATH /home/db/informix
CONSOLE INFORMIXDIR/log/console.log
ALARMPROGRAM INFORMIXDIR/etc/log_full.sh
DBSPACETEMP
其它参数暂时默认即可。
NOTE：第一次修改onconfig.front文件的时候，务必在PHYDBS参数后写上rootdbs，而不要写phydbs01，否则初始化失败。
n 设置INFORMIXDIR/etc/sqlhosts文件
编辑sqlhosts文件，加入配置的informix的信息，其中severname、portname 分别与informix的.profile中的INFORMIXSERVER及/etc/services下的端口号对应。
servername ontlitcp your_host_name portname
front onscotcp 192.168.1.10 informixport(20000)
n 编辑/etc/services文件，添加以下内容：
informixport 20000/tcp #Informix port
2，创建符号链接
# su - informix
