1.1.1.4 建库前准备

1、修改sqlhost文件

以informix用户登陆

$cd etc

$cp sqlhosts.std sqlhosts

$vi sqlhosts

用informix用户编辑/home/db/informix/etc/sqlhost文件，增加如下内容：

nettrack onipcshm nettrackdb on_shm

nettrack_net onsoctcp nettrackdb sqlexec

2、以informix用户配置$INFORMIXDIR/etc/onconfig.nettrack

以informix用户登陆

$cd etc

$cp onconfig.std onconfig.nettrack

$vi onconfig.nettrack

将onconfig.nettrack文件中的所有/usr/informix都替换成数据库的实际安装路径/home/db/informix；

在vi下执行 %s/\/usr\/informix/\/home\/db\/informix/g 进行替换

设置数据库参数信息如下：

DBSERVERNAME nettrack # Name of default database server

DBSERVERALIASES nettrack_net # List of alternate dbservernames

NETTYPE ipcshm，1，50，CPU # Configure poll thread(s) for nettype

NETTYPE soctcp，3，200，NET # Configure poll thread(s) for nettype

OPTCOMPIND 2 # To hint the optimizer

ROOTNAME rootdbs # Root dbspace name

ROOTPATH /home/db/informix/bssdbs/rootdbs # Path for device containing root dbspace

RESIDENT 1

建议不使用日志备份：

TAPEDEV /dev/null # Tape device pat

LTAPEDEV /dev/null # Log tape device path

增加参数：（增加SQL会话缓存参数）

STMT_CACHE 1 # SQL STMT CACHE: 1-ON

依据实地设备状况设置如下参数：

ROOTSIZE # Size of root dbspace (Kbytes)

PHYSFILE # Physical log file size (Kbytes)

LOGFILES # Number of logical log files

LOGSIZE # Logical log size (Kbytes)

LOCKS # Maximum number of locks

BUFFERS # Maximum number of shared buffers

NUMAIOVPS # Number of IO vps

MULTIPROCESSOR # 0 for single-processor, 1 for multi-processor

NUMCPUVPS # Number of user (cpu) vps

SINGLE_CPU_VP # If non-zero, limit number of cpu vps to one

PHYSBUFF # Physical log buffer size (Kbytes)

LOGBUFF # Logical log buffer size (Kbytes)

SHMBASE # Shared memory base address

SHMVIRTSIZE # initial virtual shared memory segment size

SHMADD # Size of new shared memory segments (Kbytes)

SHMTOTAL # Total shared memory (Kbytes). 0=>unlimited

CKPTINTVL # Check point interval (in sec)

其他参数，根据实地数据库设备配置状况进行优化配置。

3、创建链接文件

#su - informix

$mkdir bssdbs

$cd bssdbs

$ln -s /home/db/informix/bssdbs/rootdbs rootdbs

$ln -s /dev/raw/raw11 phydbs

$ln -s /dev/raw/raw12 logdbs

$ln -s /dev/raw/raw13 blobdbs

$ln -s /dev/raw/raw14 tmpdbs

$ln -s /dev/raw/raw15 data0tbs01

$ln -s /dev/raw/raw16 indextbs01

$ln -s /dev/raw/raw17 ywdattbs01

$ln -s /dev/raw/raw18 ywdattbs02

$ln -s /dev/raw/raw19 ywdattbs03

$ln -s /dev/raw/raw20 ywdattbs04

$ln -s /dev/raw/raw21 ywdattbs05

$ln -s /dev/raw/raw22 ywdattbs06

$ln -s /dev/raw/raw23 ywdattbs07

$ln -s /dev/raw/raw24 ywdattbs08

1.1.1.5 以root用户更改卷属性

#chown －R informix:informix /dev/bssvg01/

#chown －R informix:informix /dev/raw/

注意：系统重启后，设备属性将还原，需要在系统启动文件中/etc/rc.d/rc.local加入上述修改设备块属性的语句。

1.1.1.6 创建数据库

$oninit –ivy

$onstat -

以informix用户，首先使用命令：onmode –s；将数据库切换至单用户模式而后执行命令：onmode -BC 1； onmode -BC 2；取消数据空间chunck的大小限制（即允许添加2G以上的空间块）

$onspaces –c –d phydbs –p /home/db/informix/bssdbs/phydbs -o 0 -s 20000000

$onspaces –c –d logdbs –p /home/db/informix/bssdbs/logdbs -o 0 -s 40000000

$onspaces -c -b blobdbs -g 32 -p /home/db/informix/bssdbs/blobdbs -o 0 -s 480000

(注意：-s参数后定义的blob空间大小，须为 –g参数后定义的页大小的倍数；此处页大小定义为32K)

$onspaces -c -d tmpdbs –t -p /home/db/informix/bssdbs/tmpdbs -o 0 -s 20000000

$onspaces -c -d data0tbs01 -p/home/db/informix/bssdbs/data0tbs01 -o 0 -s 40000000

$onspaces -c -d indextbs01 -p /home/db/informix/bssdbs/indextbs01 -o 0 -s 80000000

$onspaces -c -d ywdattbs01 -p /home/db/informix/bssdbs/ywdattbs01 -o 0 -s 30000000

$onspaces -c -d ywdattbs02 -p /home/db/informix/bssdbs/ywdattbs02 -o 0 -s 30000000

$onspaces -c -d ywdattbs03 -p /home/db/informix/bssdbs/ywdattbs03 -o 0 -s 30000000

$onspaces -c -d ywdattbs04 -p /home/db/informix/bssdbs/ywdattbs04 -o 0 -s 30000000

$onspaces -c -d ywdattbs05 -p /home/db/informix/bssdbs/ywdattbs05 -o 0 -s 30000000

$onspaces -c -d ywdattbs06 -p /home/db/informix/bssdbs/ywdattbs06 -o 0 -s 30000000

$onspaces -c -d ywdattbs07 -p /home/db/informix/bssdbs/ywdattbs07 -o 0 -s 30000000

$onspaces -c -d ywdattbs08 -p /home/db/informix/bssdbs/ywdattbs08 -o 0 -s 30000000

1.1.1.7 添加逻辑日志块

以informix用户，使用onparams命令增加逻辑日志块，数据库至少应创建200个日志块，每块大小为20M；（建议完成此步操作后，使用ontape -s -L 0对数据库做零级备份，而后将数据库初始时建立的逻辑日志块删除）

2) 添加物理日志的逻辑空间

以informix用户，使用onparams命令创建物理日志的逻辑空间

（phydbs的逻辑空间必须小于phydbs的物理空间）

使用onparams改变物理日志位置和大小

$onparams –p –s 10000000 –d phydbs –y

使用onparams逻辑日志

$onparams –a –d logdbs –s 20000(执行200次)

3) 备份数据库

以informix用户，使用ontape -s -L 0对数据库做0级备份

4) 创建ywjk库（初始应用数据库）

以informix用户重启数据库:

关闭：onmode -ky

启动：oninit –vy

解压缩ywjk.tar.gz

tar xvfz ywjk.tar.gz

导入应用数据库：

dbimport ywjk -d data0tbs01 -l buffered

5) 修改数据库日志模式为无缓冲的日志模式

以informix用户，使用命令：ontape -s -U ywjk

1) 以informix用户建立表索引

#dbaccess ywjk<<!

>update statistics high;

7) 添加系统自启动/关闭数据库脚本

以root用户将infd文件拷贝至/etc/rc.d/init.d

cd /etc/rc.d/init.d

chmod 755 infd

cd /etc/rc.d/rc3.d （系统运行级别“3”的自启动脚本目录）

ln -s /etc/rc.d/init.d/infd S99infd

ln -s /etc/rc.d/init.d/infd K99infd
