Oracle 环境搭建

源端 OGG 依赖 Oracle 环境，可安装 Oracle instant client，如果源端和数据库在同一台服务器则不需要此小节的步骤。

下载地址：https://www.oracle.com/database/technologies/instant-client/linux-x86-64-downloads.html

rpm -ivh oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm

默认安装到 /usr/lib 的 Oracle 目录

vi ~/.bash_profile

export ORACLE_HOME=/usr/lib/oracle/11.2/client64
export TNS_ADMIN=$ORACLE_HOME/network/admin
export ORACLE_BASE=/usr/lib/oracle/11.2
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$PATH
export PATH

source 使环境变量生效。

配置监听的数据库 tns 文件信息

mkdir -p /usr/lib/oracle/11.2/client64/network/admin

vi tnsnames.ora

ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.51.213)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ORCL)
)
)

目标端 ogg 配置

kafka 解压配置

环境变量配置

export OGG_HOME=/opt/ogg4bigdata # OGGforBigdata解压目录
export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/amd64:$JAVA_HOME/jre/lib/amd64/server:$JAVA_HOME/jre/lib/amd64/libjsig.so:$JAVA_HOME/jre/lib/amd64/server/libjvm.so:$OGG_HOME/lib
export PATH=$OGG_HOME:$PATH
