Question

我有3个Oracle 11g数据库，比方说DB-1（CPSBK），DB-2（ORCL_CC），DB-3（DRCPSMGT）。在CPSBK DB-1上，我使用CPSRPTL用户登录，下面给出的程序归该用户所有。

我们有一个存储过程（如下所示），当执行/运行时，会产生以下错误。单独运行时，此查询中的Delete语句可以正常工作。 SELECT（包括UNION ALLs）语句也是如此。

但是当尝试插入时，它会抛出一个错误，如下所示。我坚持这个，没有我可以在网上找到的帮助。

运行程序时的错误详细信息：

Connecting to the database CPSBK-10.227.23.239-LIVE.
ORA-02019: connection description for remote database not found
ORA-02063: preceding line from CPSBK
ORA-02063: preceding 2 lines from ORCL_CC
ORA-06512: at "CPSRPTL.PRC_MFS_CC_LOAD_DATA", line 19
ORA-06512: at line 2
Process exited.
Disconnecting from the database CPSBK-10.227.23.239-LIVE.

PL / SQL程序如下（Oracle）;这是在CPSBK（DB-1）上创建的。

此数据库中还有两个公共数据库链接，ORCL_CC＆amp; DRCPSMGT。

Answer 1

在程序中没有看到任何问题，在考虑寻求解决方案的替代方法时，如何尝试以下方法：

您可以尝试检查COMMENT是否在DELETE AND INSERT之间？
可以看到INSERT块中使用多个DBLINK，是否允许使用足够数量的开放链接？请检查open_links和open_links_per_instance（如果在RAC中）参数并根据需要增加值，然后重试。
同样，单个语句使用MERGE并将DELETE和INSERT块合并在一起。
