GoldenGate抽取Informix数据库安装及配置

GoldenGate抽取Informix数据库安装及配置

本次测试架构

l  在中间机上安装informix csdk4.10版本，并编译配置unixODBC;

l  在中间机上安装ogg for Informix 12.2，负责抽取informix主机的数据；

l  在目标端oracle节点
上安装ogg for oracle 12.2，负责接收增量数据并写入到oracle db.

安装配置

源端主机上启用cdc功能

使用dbaccess，执行 $INFORMIXDIR/etc/syscdcv1.sql

创建相应的配置表。

除此项操作外，后面所有操作都在中间机上完成。

linux下安装informix csdk

创建一个informix用户，用于负责运行OGG软件

groupadd informix

useradd informix -m -g informix

passwd informix

中间机安装unixODBC

从此处下载源代码，
http://www.unixodbc.org/
如果是64位linux，需要先设置下面的环境变量

export CFLAGS="-DBUILD_REAL_64_BIT_MODE"

编译 unixOdbc

使用root用户

./configure

make

make install

informix csdk安装及配置

修改linux机器的hosts，在linux机器上指向目标informix机器
中间机 /etc/hosts

9.1.11.45  ids_host

查看informix主机上informix服务端口
{informix:/informix/etc]cat
/etc/services

ids_svs     48012/tcp #
informix service port

并在linux机器的services看添加同样一行内容

配置环境变量，并添加到.bashrc

export INFORMIXDIR=/opt/IBM/informix

export
LD_LIBRARY_PATH=$INFORMIXDIR/lib:$INFORMIXDIR/lib/esql:$INFORMIXDIR/lib:$INFORMIXDIR/lib/esql::$INFORMIXDIR/lib/cli:$INFORMIXDIR/lib/esql

export INFORMIXSERVER=ids_host

export ONCONFIG=onconfig.ids_host

export ODBCINI=$INFORMIXDIR/odbc.ini

export
INFORMIXSQLHOSTS=$INFORMIXDIR/etc/sqlhosts

sqlhosts的内容如下

主机名称和服务名与前面设置的服务名及主机名保持一致。

ids_host        onsoctcp       9.1.11.45       ids_svs

安装ids sdk 4.10

以root用户运行
./ids_install
使用默认选项安装，但不要选择 create service option.

安装完成之后，默认所有文件是在
/opt/IBM/informix 目录，

配置odbc并测试

创建odbc.ini

该文件所在目录需要与前面指定的
ODBCINI 环境变量路径相同。
