MySQL迁移工具包Java运行时错误

Question

当我尝试在Windows中运行MySQL迁移工具包GUI时，我收到未安装状态Java的错误。Java已安装，但迁移工具包无法识别它。有人知道如何解决这个问题吗？

Answer 1

您应该真的尝试最近MySQL工作台版本的新迁移向导。MySQL迁移工具包几年前已经淘汰，并不在积极开发中。

在迁移向导上进行教程，请查看 how-to：来自Microsoft SQL Server的数据库迁移指南使用mysql workbench 。

Answer 2

井是为了使这个解决方案非常容易。 转到文件夹已安装MySQL迁移工具包。 做一个捷径。到了可执行文件的桌面 mysqlmigrameTool.exe
然后右键单击刚刚创建的快捷方式，然后在 target 上修改它，如此

"C:\Program Files (x86)\MySQL\MySQL Migration Toolkit 1.0\MySQLMigrationTool.exe" -verbose -jvm **The Path to your 32bit jvm.dll** 

.

为我的安装使用 jre1.8.0_45

"C:\Program Files (x86)\MySQL\MySQL Migration Toolkit 1.0\MySQLMigrationTool.exe" -verbose -jvm ***"C:\Program Files (x86)\Java\jre1.8.0_45\bin\client\jvm.dll"***

.

Answer 3

Anyway, if there's still somebody struggling with the MySQL Migration Toolkit and jre 1.8 I would suggest to stop bothering because after fixing the boot by setting the jvm.dll it fails performing the Reverse Engeneering step with this message:

    The schema could not be reverse engineered (error: 0).

Answer 4

I got the tool running and migrated most of the tables but is not happy with the result because many table creation failed. Still it is useful since I got the script so that I can edit it later. I used these versions

Migration Toolkit 1.0.25

IBM JRE 5.0 (I had this in system) - Had to set the JVM as mentioned by John.

Use Oracle JDBC driver for your database(12c ojdbc8) but it must be renamed to ojdbc14.jar and use.

Delete mysql-connector-java-3.1... files(3 files) from MySQL Migration Toolkit 1.0\java\lib and place mysql-connector-java-5.1.44.jar

Run the tool.

I used mysql_native_password for the MySQL user :- ALTER USER 'mysqluser'@'%' IDENTIFIED WITH mysql_native_password BY 'pass';
