最终，在Oracle端共包括16张表，2个视图，其中2个表TSRSLOB和IMAGE_LOB包括了blob和clob字段。
生成MySQL端DDL语句
可以使用Navicat的数据传输功能或其它工具直接从Oracle端生成MySQL类型的建表语句如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | mysql -uroot -plhr -h 172.72.7.35 -D lhrdb -f < ddl.sql mysql> show tables; +----------------------+ | Tables_in_lhrdb | +----------------------+ | ADDRESSES | | CARD_DETAILS | | CUSTOMERS | | IMAGE_LOB | | INVENTORIES | | LOGON | | ORDERENTRY_METADATA | | ORDERS | | ORDER_ITEMS | | PRODUCT_DESCRIPTIONS | | PRODUCT_INFORMATION | | TCUSTMER | | TCUSTORD | | TSRSLOB | | TTRGVAR | | WAREHOUSES | +----------------------+ 16 rows in set (0.01 sec) |
DDL语句如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 | /* Navicat Premium Data Transfer Source Server : ora12c Source Server Type : Oracle Source Server Version : 120200 Source Host : 192.168.1.35:1526 Source Schema : LHR Target Server Type : MySQL Target Server Version : 80099 File Encoding : 65001 Date: 28/06/2022 15:19:41 */ SET NAMES utf8;

dataX-web配置
1、新增项目
2、新增Oracle和MySQL数据源，并测试通过
1 2 3 4 | jdbc:oracle:thin:@//172.72.7.34:1521/lhrsdb jdbc:mysql://172.72.7.35:3306/lhrdb |
3、新增datax任务模板
4、构建批量任务
注意：任务构建每次只能建立一张表的迁移，所以，我们需要选择批量构建。
然后就是选择job的模板，最后就是批量创建任务。
创建完成后，点击任务管理：
可以看到，基本是每张表1个任务。任务构建成功后，默认不开启执行调度。
我们可以在后台更新数据库表来批量操作：
1 2 3 4 5 6 7 8 | mysql -uroot -plhr -D datax update job_info t set t.job_cron='0 18 15 4 7 ? 2022'; update job_info t set t.trigger_status=1; -- 日志 tailf /usr/local/datax-web-2.1.2/modules/datax-executor/bin/console.out |
更新完成后，查看界面：
等到15:18分后，刷新一下界面，如下：
发现，除了ORDERS表和PRODUCT_INFORMATION表后，其它都迁移成功了。
本人提供Oracle(OCP、OCM)、MySQL(OCP)、PostgreSQL(PGCA、PGCE、PGCM)等数据库的培训和考证业务，私聊QQ646634621或微信dbaup66，谢谢！
请问老师的secureCRT这个配置是怎么设置的
