服务器评测
Informix是IBM公司出品的关系数据库管理系统（RDBMS）家族。作为一个集成解决方案，它被定位为作为IBM在线事务处理（OLTP）旗舰级数据服务系统。 IBM对Informix和DB2都有长远的规划，两个数据库产品互相吸取对方的技术优势。在2005年早些时候，IBM推出了Informix Dynamic Server（IDS）第10版。目前最新版本的是IDS11（v11.50，代码名为“Cheetah 2”），在2008年5月6日全球同步上市，
1、#groupadd informix
#useradd -g informix informix
#passwd informix
# informix
2、vi /home/informix/.bash_profile
INFORMIXDIR=/var/informix
PATH=$INFORMIXDIR/bin:$PATH
LD_LIBRARY_PATH=$INFORMIXDIR/lib:$LD_LIBRARY_PATH
export INFORMIXDIR PATH LD_LIBRARY_PATH
3、#mkdir /usr/Java
#cd /usr/java
#/home/informix/Informix_Dynamic_Server_V11.50.UC7_Linux_x86_English/.jvm.bin
4、#cd /home/informix/Informix_Dynamic_Server_V11.50.UC7_Linux_x86_English/
#./ids_install -javahome /usr/java
按照提示，一步一步安装（不创建demo)
5、vi /home/informix/.bash_profile
ONCONFIG=onconfig.infm
SQLHOSTS=sqlhosts
DBSERVERNAME=infm
SERVERNUM=0
INFORMIXSERVER=infm
export ONCONFIG SQLHOSTS DBSERVERNAME SERVERNUM INFORMIXSERVER
#. .bash_profile
6、cd $INFORMIX/etc
cp onconfig.std onconfig.infm
vi onconfig.infm
ROOTPATH=$INFORMIXDIR/chunks/infm.rootdbs
DBSERVERNAME=infm
7、#chown -R informix:informix /var/informix
#cd $INFORMIXDIR
#mkdir chunks
cd chunks
touch infm.rootdbs
chmod 660 infm.rootdbs
onspaces -c -d rootdbs -p /var/informix/chunks/infm.rootdbs -o 0 -s 200000
8、#hostname infm
vi $INFORMIXDIR/etc/sqlhosts
infm onsoctcp infm sqlexec
infm onsoctcp infm sqlexec-ss1
9、vi /etc/hosts
127.0.0.1 infm
10、oninit -ivy
安装过程中出现的问题：
1、$oninit -ivy
Checking group membership to determine server run mode…succeeded
Reading configuration file ‘/var/informix/etc/onconfig.infm’…succeeded
Creating /INFORMIXTMP/.infxdirs…succeeded

oninit: DBSERVERNAME ‘infm’ not in sqlhosts file or sqlhosts file contents
are damaged.
刚开始我用的文件不是sqlhosts,而是sqlhosts.infm，这样不行！
2、
Starting tracing…succeeded
Initializing 8 flushers…succeeded
FAILED
WARNING: server initialization failed, or possibly timed out (if -w was used).
Check the message log, online.log, for errors.
在online.log中发现：
The chunk ‘/var/informix/chunks/infm.rootdbs’ must have READ/WRITE permissions for owner and group (660).
cd $INFORMIXDIR/chunks
$ll
-rw-rw-r– 1 informix informix 0 12-09 22:44 infm.rootdbs
必须是660
chmod 660 infm.rootdbs
