使用 OceanBase 导数工具从 OceanBase 集群 MySQL 租户迁移数据到 Oracle 租户 - OceanBase 数据库 V4.3.5

本文将介绍如何使用 OceanBase 导数工具从 OceanBase 数据库 MySQL 租户迁移数据到 Oracle 租户。

OceanBase 导数工具简介

OceanBase 导数工具包括导出工具 obdumper 和导入工具 obloader。

obdumper 是一款使用 Java 开发的客户端导出工具。可以使用该工具将 OceanBase 数据库中定义的对象和数据导出到文件中。有关 obdumper 的详细信息请参见 obdumper 简介。
obloader 是一款使用 Java 开发的客户端导入工具。该工具提供了非常灵活的命令行选项，可在多种复杂的场景下，将定义和数据导入到 OceanBase 中。有关 obloader 的详细信息请参见 obloader 简介。

操作步骤

准备 obdumper 和 obloader 运行环境。详见准备环境和下载工具。
创建存放导出数据的目录。

导出表结构/数据。

[xxx@xxx /ob-loader-dumper-4.0.0-RELEASE/bin]
$./obdumper -h <主机IP> -P <端⼝> -u <⽤⼾> -p <密码> [--sys-user <sys 租户下用户名> --sys-password <sys 租户下特定用户的密码>] -c <集群名称> -t <租⼾> -D <Schema 库名> [--ddl] [--csv|--sql] [--all|--table '表名'] -f <数据⽂件或者⽬录>

说明

使用 OceanBase 物理节点的主机地址和端口导出数据时，无需指定 -c 选项。
有关 obdumper 命令行选项的详细信息，请参见命令行选项。

导入表结构/数据。

[xxx@xxx /ob-loader-dumper-4.0.0-RELEASE/bin]
$./obloader -h <主机IP> -P <端⼝> -u <⽤⼾> -p <密码>  --sys-user <sys 租户下的 root 用户或 proxyro 用户> --sys-password <sys 租⼾下的账⼾密码> -c <集群> -t <租⼾> -D <Schema 库名> [--ddl] [--csv|--sql] [--all|--table '表名'] -f <数据⽂件或者⽬录>

说明

使用 OceanBase 物理节点的主机地址和端口导入数据时，无需指定 -c 选项。
有关 obloader 命令行选项的详细信息，请参见命令行选项。

导出和导入数据示例

下表为示例中使用的数据库信息：

数据库信息	示例值
集群名	test4000
OceanBase DataBase Proxy (ODP) 主机地址	xxx.xxx.xxx.xxx
OceanBase DataBase Proxy (ODP) 端口号	2883
sys 租户下 root 用户的密码	******
源租户名称（MySQL 模式）	mysql001
租户 mysql001 的用户账号（要求读写权限）	obdumper_user01
租户 mysql001 下用户 obdumper_user01 的密码	******
租户 mysql001 下 Schema 库名称	test_data
目标租户名称（Oracle 模式）	oracle001
租户 oracle001 的用户账号（要求读写权限）	obloader_user01
租户 oracle001 下用户 obloader_user01 的密码	******
租户 oracle001 下 Schema 库名称	OBLOADER_USER01

表结构迁移

使用 obdumper 和 obloader 进行表结构迁移时，需要指定 --sys-user 和 --sys-password 选项，获取表结构元数据信息。如果未指定该选项，导出/导入功能和性能可能会受到较大的影响。

说明

--sys-user 选项用于连接 sys 租户下拥有特定权限的用户。导出时如果未指定 --sys-user 选项，默认指定的是 --sys-user root。

导出 DDL 定义文件

场景描述：从集群 test4000 下的租户 mysql001 里的 Schema test_data 中，导出所有已支持的对象定义语句到 /home/admin/test_migrate_data/ddl_data 目录。

示例语句如下。

      `col3` int(11),
      primary key (`col1`)
)

导入 DDL 定义文件

场景描述：将从集群 test4000 下的租户 mysql001 里的 Schema test_data 导出到 /home/admin/test_migrate_data/ddl_data 目录下所有已支持的定义信息，导入到集群 test4000 下的租户 oracle001 里的 Schema obloader_user01 中。

注意

从 MySQL 租户里导出的 DDL 文件不符合 Oracle 租户的语法要求，所以从 MySQL 租户里导出的 DDL 文件先修改成符合 Oracle 租户的语法要求的 DDL 文件后，再导入 Oracle 租户中。

例如，从租户 mysql001 里导出的 DDL 文件，修改规则如下：

去掉 if not exists 关键字和单引号。
把数据类型修改为 Oracle 模式通用的数据类型：
- 将 int(11) 改为 number(11)。
- 将 varchar(50) 改为 varchar2(50)。
去掉默认字符序和字符集参数 default charset=utf8mb4、default collate=utf8mb4_general_ci。

有关 Oracle 模式数据类型的详细信息，请参见内建数据类型概述。

示例语句如下。

表数据迁移

以下将以导出 CSV 数据文件和导入 CSV 数据文件为例进行介绍使用 obdumper 和 obloader 进行表数据迁移。

导出 CSV 数据文件

文件类型定义：CSV 数据文件（后缀名 .csv）是逗号分隔值文件格式，CSV 数据文件以纯文本形式存储表格数据，可通过文本编辑器等工具或者 Excel 打开。

场景描述：从集群 test4000 下的租户 mysql001 里的 Schema test_data 中，导出所有已支持对象的数据到 /home/admin/test_migrate_data/csv_data 目录，数据格式为 CSV 格式。

导入 CSV 数据文件

场景描述：将从集群 test4000 下的租户 mysql001 里的 Schema test_data 导出到 /home/admin/test_migrate_data/csv_data 目录下所有已支持的 CSV 数据文件，导入到集群 test4000 下的租户 oracle001 里的 Schema OBLOADER_USER01 中。

注意

需要将租户 mysql001 里的 Schema test_data 导出的目录 /home/admin/test_migrate_data/csv_data/data/ 下的 test_data 名称修改为 OBLOADER_USER01。
将导出的 CSV 文件名中的表名中的英文字母改为大写。

示例语句如下：

bash [root@xxx /home/admin/test_migrate_data/csv_data/data]# mv test_data OBLOADER_USER01 [root@xxx /home/admin/test_migrate_data/csv_data/data]# cd OBLOADER_USER01/TABLE [root@xxx /home/admin/test_migrate_data/csv_data/data/OBLOADER_USER01/TABLE]# ls test_tbl1.1.0.csv test_tbl2.1.0.csv [root@xxx /home/admin/test_migrate_data/csv_data/data/OBLOADER_USER01/TABLE]# mv test_tbl1.1.0.csv TEST_TBL1.1.0.csv [root@xxx /home/admin/test_migrate_data/csv_data/data/OBLOADER_USER01/TABLE]# mv test_tbl2.1.0.csv TEST_TBL2.1.0.csv <code></code>
