Question

我在asp.net mvc中有一个使用Oracle数据库的项目。当我在很短的时间内发出请求时，它在localhost上工作得很好，在一些空闲时间之后，如果我发出相同的请求，我会得到错误（System.Net.Sockets.SocketException）：

连接尝试失败，因为连接方没有在一段时间后正确回应，或建立连接失败，因为连接的主机无法响应

Linha 306:            produto = produto.Where(x => x.DESC_PRODUTO.ToUpper().Contains(palavra1));
Linha 307:            }
Linha 308: ===>        var categoria = await (from b in db2.MGL_PRODUTOS_GRUPO_SITE_VW 
Linha 309:                                   join p in produto on b.ID equals p.COMGPRO_ID

Linha错误：308
