通过核查，报错中涉及的 rowid 已经无法从 Oracle 数据库中查询。尝试通过设置参数 deliver2store.logminer.enable_skip_revise_valid_rowid_exception=true 解决问题，但没成功，仍然报错。

deliver2store.logminer.enable_skip_revise_valid_rowid_exception 参数的默认值为 false，用于设置是否跳过修正 rowid 引起的异常。

问题原因

OMS 的 Store 组件处理大事务时序列化出现问题（原因未知）。

解决方法

您可以通过设置参数 deliver2store.logminer.enable_level_store=false，关闭 Store 组件的大事务处理机制。

请注意，设置该参数会导致内存使用量上涨。必要时请修改 Store 组件的内存配置，以免遇到 GC 问题。
