MogDB/openGauss 生态工具-MTK(Migration ToolKit) 数据库迁移
一、准备环境
1. 源库创建（Oracle）
创建Oracle 11.2.0.4
docker pull registry.cn-hangzhou.aliyuncs.com/lhrbest/oracle_11g_ee_lhr_11.2.0.4:1.0
docker run -itd --name oracle -h oracle --privileged=true -p 1521:1521 -p 222:22 -p 1158:1158 lhrbest/oracle_11g_ee_lhr_11.2.0.4:1.0 initMTK程序迁移Oracle需要安装Oracle客户端
安装Oracle客户端
wget https://download.oracle.com/otn_software/linux/instantclient/211000/oracle-instantclient-basic-21.1.0.0.0-1.x86_64.rpm
wget https://download.oracle.com/otn_software/linux/instantclient/211000/oracle-instantclient-sqlplus-21.1.0.0.0-1.x86_64.rpm
rpm -ivh oracle-instantclient-basic-21.1.0.0.0-1.x86_64.rpm oracle-instantclient-sqlplus-21.1.0.0.0-1.x86_64.rpm
export LD_LIBRARY_PATH=/usr/lib/oracle/21/client64/lib2. 目标库创建（MogDB）
二、迁移
1. 上传程序，编写配置文件
迁移为Oracle下的scott用户
编写配置文件
[root@mogdb-kernel-0005 mtk]# cat mtk_config.json
{
"source": {
"type": "oracle",
"connect": {
"version": "",
"host": "172.16.0.176",

},

}
},

},
"parameter": {
"dropExistingObject": true,
"truncTable": true,
"ignoreTableDDLCompErr": true,
"parallelInsert": 1
}
},
"limit": {

},
"object": {
"schemas": [
"SCOTT"
]
},
"dataOnly": false ,
"schemaOnly": false,
"reportFile": "./report_Oracle2OpenGauss_all.html"
}2. 迁移
执行迁移命令
[root@mogdb-kernel-0005 mtk]# ./mtk -c mtk_config.json --reportFile mtk_report.html --logfile mtk_report.log --debug
