问题 I have to connect to a remote Oracle DBMS into my .NET C# web service Is request the client Oracle installation? Why?

When it is enabled, the first person who logs in (ex: USER1) updates a record and the MODIFIED_BY is USER1, but when a different user heads into the website after,

问题 I have an WebAPI service using ODP.NET to make connections to several oracle databases. Normally the web service would be hit several times a second and will never have long periods on inactivity. In our test site however, we did not use it for 2-3 days. This morning, we hit the service and got "connection request timeout" exceptions from ODP.NET, suggesting that the connection pool was out of available connections. We are closing the connections after use. The service was working fine before
