mysql bigint类型，oracle用什么类型替换 number吗？使用后“”系统日志“”报转换出错

lcn使用tc的事务使用oracle管理，手动创建trigger后，原本自动创建的id主键数据类型为bigint，oracle使用number(33)后，点击http://127.0.0.1:7970/admin/index.html，“”系统日志“”按钮，弹出“”系统日志已被禁用，将返回首页“”，tc后台控制台显示下面：
java.lang.ClassCastException: java.math.BigDecimal cannot be cast to java.lang.Long；

我想问下mysql bigint类型，oracle用什么类型替换 number吗？帮帮解答下，各位大佬们，急解决！

Start by reproducing the failure from http://127.0.0.1:7970/admin/index.html by opening the “系统日志” button, then inspect the TC backend console and its reported ClassCastException. The issue does not name a source file, test, or expected database mapping, so the required change and completion criteria need clarification.
