### Ⅲ. Describe what you expected to happen
我想在db模式下使用oracle做事务管理

### Ⅳ. How to reproduce it (as minimally and precisely as possible)

1. xxx
2. xxx
3. xxx

### Ⅴ. Anything else we need to know?

### Ⅵ. Environment:

- JDK version : 1.8
- OS : Mac os
- Others:

Start with AbstractTableMetaCache.java:69 and AbstractConnectionProxy.java:116 to trace the reported table-metadata failure. Review the Oracle-related database behavior described in the issue, then inspect GoodsMapper.xml and IGoodsMapper.insertTest for the failing insert. Done means a reproducible Oracle DB-mode case is identified and the transaction succeeds without the reported metadata or constraint errors.
