MTK 2.9.2 迁移 Oracle 11g 至 openGauss 5.0.0 操作指南
尚雷 [openGauss](javascript:void(0);) 2023-08-04 18:01 发表于四川
前言: 最近在进行一些去 O 的验证测试，之前测试过 MTK 迁移 Oracle 到 MogDB，正好测试下 Oracle 到 openGauss 的迁移，于是做了如下测试，并整理记录成文，还望对此熟悉的朋友多多指正。
一、简介
MTK 全称(Database Migration Toolkit)，可进行 Oracle/DB2/MySQL/openGauss/SqlServer/Informix 等数据库异构迁移，支持 Oracle/MySQL/DB2->openGauss 的存储过程，函数，触发器，包迁移。MTK 支持多种数据类型，并可在迁移时对性能进行调整，还支持结构和数据的分离。
本次采用恩墨公司 MTK 迁移工具，进行 Oracle 11g 到 openGauss 5.0 数据迁移测试。
本次迁移采用 MTK 最新版 2.9.2(2023 年 7 月 30 日)。
MTK 安装比较灵活，其可以安装在源端和目标端甚至可单独部署在一台可远程访问源端及目标端的单独服务器上。
MTK 迁移 Oracle 数据库时，需在部署 MTK 的服务器上安装 Oracle 客户端 Oracle Instant Client。
二、环境概述
本次进行 Oracle 11g 到 openGauss 5.0.0 迁移测试，如进行生产迁移，还需考虑更多步骤细节，详情请查看恩墨 MTK 官方文档[https://docs.mogdb.io/zh/mtk/v2.0/overview]。
三、安装部署
3.1 安装 Oracle 客户端
MTK 迁移 Oracle 数据库，需要在部署 MTK 的服务器上安装 Oracle 11g 客户端，本次选择采用 rpm 包来安装客户端。
登录https://www.oracle.com/database/technologies/instant-client/linux-x86-64-downloads.html选择下载 Version 11.2.0.4.0 版本客户端。
-- 1) 安装oracle-client rpm包-- MTK服务器下载如下四个 oracle-client rpm包[root@opensource-db soft]# lltotal 61400-rw-r--r-- 1 root root 59865008 Jul 28 16:46 oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm-rw-r--r-- 1 root root 610222 Jul 28 16:47 oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm-rw-r--r-- 1 root root 1564169 Jul 28 16:47 oracle-instantclient11.2-jdbc-11.2.0.4.0-1.x86_64.rpm-rw-r--r-- 1 root root 828333 Jul 28 16:48 oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64.rpm-- root 用户安装rpm包[root@opensource-db soft]# rpm -ivh oracle*.rpm-- oracle-instantclient11.2*.rpm 包安装目录在 /usr/lib/oracle 目录下[root@opensource-db ~]# cd /usr/lib[root@opensource-db lib]# tree oracle/oracle/└── 11.2 └── client64 ├── bin │ ├── adrci │ ├── genezi │ └── sqlplus ├── lib │ ├── glogin.sql │ ├── libclntsh.so -> libclntsh.so.11.1 │ ├── libclntsh.so.11.1 │ ├── libheteroxa11.so │ ├── libnnz11.so │ ├── libocci.so -> libocci.so.11.1 │ ├── libocci.so.11.1 │ ├── libociei.so │ ├── libocijdbc11.so │ ├── libsqlplusic.so │ ├── libsqlplus.so │ ├── ojdbc5.jar │ ├── ojdbc6.jar │ ├── orai18n.jar │ ├── orai18n-mapping.jar │ ├── ottclasses.zip │ └── xstreams.jar └── network └── admin └── tnsnames.ora6 directories, 21 files
-- 2) 配置环境变量-- omm 用户[omm@opensource-db ~]$ cat >>/home/omm/.bash_profile<<EOFexport LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client64/libexport TNS_ADMIN=/usr/lib/oracle/11.2/client64/network/adminEOF[omm@opensource-db ~]$ source /home/omm/.bash_profile
-- 3) 创建sqlplus链接-- 此时执行sqlplus会报错[omm@opensource-db ~]$ sqlplus-bash: sqlplus: command not found
# 问题原因，因为安装sqlplus客户端后，会链接生成/bin/sqlplus64[omm@opensource-db ~]$ sqlplus64
SQL*Plus: Release 11.2.0.4.0 Production on Sun Jul 30 23:22:22 2023

3.2 部署 MTK
3.2.1 下载 MTK
登录 https://docs.mogdb.io/zh/mtk/v2.0/release-2.9网站，根据部署 MTK 服务器类型选择合适的 MTK 版本，本次选择最新版 MTK2.9.2。
将下载的 mtk_2.9.2_linux_amd64.tar.gz 软件上传到 MTK 服务器 omm 用户。
3.2.2 校验 MTK
使用 sha256sum 命令对下载的安装包进行校验，并和官网 cheksum 值进行比对。
[omm@opensource-db ~]$ sha256sum mtk_2.9.2_linux_amd64.tar.gz cc0cf328f0d4484f569e8520481dc4a3fd4d4acd46ac4a643c0e8e5ccdcfe551 mtk_2.9.2_linux_amd64.tar.gz
复制代码
如下是官网 mtk_2.9.2_linux_amd64.tar.gz chechsum 值。
3.2.3 解压 MTK
MTK 无需安装，只需解压即可。
[omm@opensource-db ~]$ tar -zxvf mtk_2.9.2_linux_amd64.tar.gz mtk_2.9.2_linux_amd64/CHANGELOG.mdmtk_2.9.2_linux_amd64/README.mdmtk_2.9.2_linux_amd64/example/db22mogdb.jsonmtk_2.9.2_linux_amd64/example/db22mogdb.yamlmtk_2.9.2_linux_amd64/example/db22mysql.jsonmtk_2.9.2_linux_amd64/example/db22mysql.yamlmtk_2.9.2_linux_amd64/example/informix2mogdb.jsonmtk_2.9.2_linux_amd64/example/informix2mogdb.yamlmtk_2.9.2_linux_amd64/example/mysql2mogdb.jsonmtk_2.9.2_linux_amd64/example/mysql2mogdb.yamlmtk_2.9.2_linux_amd64/example/oracle2mogdb.jsonmtk_2.9.2_linux_amd64/example/oracle2mogdb.yamlmtk_2.9.2_linux_amd64/example/pg2mogdb.jsonmtk_2.9.2_linux_amd64/example/pg2mogdb.yamlmtk_2.9.2_linux_amd64/example/sqlserver2mogdb.jsonmtk_2.9.2_linux_amd64/example/sqlserver2mogdb.yamlmtk_2.9.2_linux_amd64/mtk

3.4 MTK 初始化项目
使用 MTK 迁移，需要首先在 MTK 服务器进行项目的初始化，初始化方式如下
-- 通过mtk init-project --help命令可以查看mtk所支持的数据库[omm@opensource-db ~]$ cd /home/omm/mtk_2.9.2_linux_amd64[omm@opensource-db mtk_2.9.2_linux_amd64]$ ./mtk init-project --helpInitialise a typical mtk project tree. Top directory will be created under project base dir.
Usage: mtk init-project [project_name|--name project_name] [flags]
Examples: mtk init-project ora2og --sourceDBType oracle --targetDBType mogdb
Flags: --detail Whether to output full parameters, default output simple parameters -h, --help help for init-project -n, --name string specify project name -s, --sourceDBType string specify source database type oracle, mysql, db2, sqlserver, dm, informix, opengauss, mogdb, postgresql (default "oracle") -t, --targetDBType string specify target database type opengauss, mogdb, mysql, postgresql, db2 (default "mogdb")
Global Flags: --caseSensitive int Object case parameters in SQL statements. 1 - lower case 2 - upper case 3 - Keep it the same as the source database. -c, --config string Set mtk config file. Support json,yaml. [env MTK_CONFIG] (default "mtk.json") -d, --debug Set the debug mode. Not necessary for the normal usage. [env MTK_DEBUG] --disableIgnoreCase Disable ignoring case queries --enableSyncCompTabPro Enable Synchronize table compressed properties --file export to file --fileType string Indicates the type of a file when data is to be exported to a file. support csv,sql --license string Specify the license file --noTerminalReport The terminal does not print an overview of the migration report -p, --parallel int Specify the parallelism. the degree of parallelism is now only useful when migrating table data and parallelism when creating an index. (default 1) --path string Indicates the directory of a file to which data is to be exported. Default value is config.target.parameter.path. If not configured, the system default value ./data Command Value > Config Value > MTK Default Value --preRun preRun check. -r, --reportFile string Set mtk report file or dir. If it is a file, use the file directory. Default value is ./report report directory format [./report/reportYYYYMMDDHHMISS] ./report/report20210101121314 --schemas string the Migrate schema,Separated by commas.(schema1,schema2,db1) --tableSkip stringArray Define table split. Can be specified multiple times. format schema.tableName --tableSkip MTK.TABLE01 --tableSkip MTK.TABLE02 --tables string the Migrate tables,Separated by commas.(tab1,schema1.tab1)-- -s 代表源端所支持的数据库类型-- -t 代表目标端所支持的数据库类型-- 通过以上内容可以看到mtk支持源端Oracle数据库和目标端openGauss数据库的迁移
-- 使用如下命令初始化项目[omm@opensource-db mtk_2.9.2_linux_amd64]$ ./mtk init-project -s oracle -t opengauss -n ora2gaussdb[omm@opensource-db mtk_2.9.2_linux_amd64]$ tree -f ora2gaussdb/ora2gaussdb├── ora2gaussdb/config│ └── ora2gaussdb/config/mtk.json├── ora2gaussdb/data├── ora2gaussdb/report└── ora2gaussdb/schema

以下是 mtk 部分配置参数及含义描述：
3.5.2 检查配置文件
-- 通过预运行检查配置文件有无错误[omm@opensource-db mtk_2.9.2_linux_amd64]$ ./mtk check-config -c ora2gaussdb/config/mtk.json --preRunuse config : ora2gaussdb/config/mtk.jsonThere is no error in the configuration file# 出现如上信息提示配置文件配置正确
# 注意，如果只迁移schema，在配置object时，不能将table和schema同时写，否则检查时会报如下错误：[omm@opensource-db mtk_2.9.2_linux_amd64]$ ./mtk check-config -c ora2gaussdb/config/mtk.json --preRunuse config : ora2gaussdb/config/mtk.jsonError : schema and tables cannot exist together schema and tables cannot exist together
复制代码
四、执行迁移
4.1 迁移命令
迁移可以选择只迁移 schema、迁移整个库，或者迁移数据库某些表对象。
-- 通常有如下迁移方式-- 整库迁移mtk -c ora2gaussdb/config/mtk.json
-- 只迁移schemamtk -c ora2gaussdb/config/mtk.json --schemaOnly
-- 只迁移数据mtk -c ora2gaussdb/config/mtk.json --file --dataOnly
-- 还可以根据需要对部分对象进行迁移-- 可参加官方文档：https://docs.mogdb.io/zh/mtk/v2.0/mtk-usage (分步迁移)
-- 执行迁移后，还可以通过如下方式生成相应迁移报告-- 导出整库迁移报告mtk -c ora2gaussdb/config/mtk.json --file
-- 导出仅含schema的信息报告mtk -c ora2gaussdb/config/mtk.json --file --schemaOnly
-- 导出仅含数据的信息报告mtk -c ora2gaussdb/config/mtk.json --file --dataOnly
