OracleReader：抽取oracle大数据量时候，报错：java.sql.SQLRecoverableException:io错误 连接超时（Read failed）

在使用oraclereader抽取oracle的几十亿条数据量时候，报错。

Start at the OracleReader entry point and review the reported java.sql.SQLRecoverableException, including the linked screenshot, during very large Oracle extractions. Reproduce the read-timeout failure with a comparable data volume, identify the cause, and verify that the extraction completes reliably without the reported error.
