pengyu0929 commented on issue #633: omega不能正常重连alpha URL: https://github.com/apache/servicecomb-pack/issues/633#issuecomment-575450542 使用的0.4.0版本； 这个不是数据连接的问题，是因为你们并没有兼容ORACLE数据库，ORACLE数据库是不支持存储空字符串的，而`SagaStartedEvent`的构造函数中`compensationMethod`属性使用`空字符串`初始化，并且该字段在`txevent`表中是`非null`的，所以报了数据插入异常，`SagaEndedEvent`也有同样的问题； ```java public class SagaStartedEvent extends TxEvent { public SagaStartedEvent(String globalTxId, String localTxId, int timeout) { // use "" instead of null as compensationMethod requires not null in sql super(EventType.SagaStartedEvent, globalTxId, localTxId, null, "", timeout, "", 0); } } ``` ```java public class SagaEndedEvent extends TxEvent { SagaEndedEvent(String globalTxId, String localTxId) { super(EventType.SagaEndedEvent, globalTxId, localTxId, null, "", 0, "", 0); } } ``` 我提个建议，你们是否需要重构下alpha端的sql，继而兼容多种数据库呢？
