我陷入了分配给我的基于java的问题。
我有一个Oracle Integrator（Web ADI），可将记录从基于excel的模板上传到Oracle Apps。有一些基于Java的值列表（LOV）附加到模板。我在这些LOV中遇到问题，因为代码编写得很糟糕。成功上传了多达450条记录，但是当我们将负载增加到500时，会出现以下错误： “BneBaseSQL.executeQuery：堆栈跟踪：java.sql.SQLException：ORA-01000：超出最大打开游标数”
我已经尝试将open_cursors限制更改为1000，这解决了我的问题，但我们可能有更大的负载高达5000条记录。所以我们想在代码中解决问题。
我分析了代码，并且发现错误在Validator类中。实际上，所有记录都应该一次性获取，然后可以从结果集中使用。但据我所知，它将选择一条记录并执行操作，并在这种情况下打开超过db open_cursors限制的那么多游标。
任何人都可以查看代码并建议我如何重写验证器。
我正在附加sql和验证器代码。
