数据源数据库物理DG
本地数据库测试库（无任何业务）

本地数据库有一个很简单的存储过程，就是凌晨通过DBLINK去数据源数据库抓取昨天数据

但是每天上班查看抓取都失败，手动执行任何一条抓取数据语句会报出ORA1555

SQL> INSERT INTO VC_VIRTUAL_CARD_INFO SELECT * FROM VC_VIRTUAL_CARD_INFO@dblink_dataextraction;
INSERT INTO VC_VIRTUAL_CARD_INFO SELECT * FROM VC_VIRTUAL_CARD_INFO@dblink_dataextraction
*
ERROR at line 1:
ORA-01555: snapshot too old: rollback segment number 10 with name
"_SYSSMU10_3271578125$" too small
ORA-02063: preceding line from DBLINK_DATAEXTRACTION

在本地数据库手动执行ROLLBACK后不会报错，执行存储过程也可以顺利完成数据抓取，但第二天凌晨自动运行又会失败，如此循环
