问题 My managed ODP.net webapp works locally but when deploying it to a server, it fails with the error: "TNS:listener does not currently know of service requested in connect descriptor" From looking around, it seems like this is because it can't get to the tnsnames.ora file. I have tried the following with no success: Placing a tnsnames.ora file (the same one that works locally) into an [oracle home][product]...\network\admin folder. Setting a TNS_ADMIN setting in the Managed ODP's web.config

问题 I have a web application which uses Oracle.DataAccess.dll to communicate with an Oracle db. The web application deployed on 32 bit windows system works but not on windows server 2008 64 bit.

问题 I'm modifying a Winforms app to use connection pooling so data access can occur in background threads. The business logic is implemented in PL/SQL and there are a couple of security related stored procedures that have to be called in order to make use of the business logic. What I need is a way to tell if the connection has been used without a round-trip to the database. I don't think I can keep track of them in a HashSet because I doubt Equals or even ReferenceEquals could be relied upon.

问题 I am using OracleBulkCopy Class with reference to Oracle.DataAccess.dll. I want to use Oracle.ManagedDataAccess.dll for easy deployment. But then I got build error "OracleBulkCopy not found" Does anyone know why OracleBulkCopy is not included in Oracle.ManagedDataAccess.dll? 回答1: You are correct. At the time of this writing OracleBulkCopy is not supported in ODP.NET, Managed Driver. The reason is is not included was simply a matter of feature priority. As the Managed Driver becomes more

问题 I've successfully used Oracle Database 11g Release 2 (11.2.0.1.0) to connect oracle from .Net. (in reference Oracle.DataAccess.dll version was 2.112.1.0). But when I installed ODP.NET and when I am trying to connect to oracle, it gives me an error: "ORA-12154: TNS:could not resolve the connect identifier specified". How can I solve this problem? Thanks! 回答1: This usually occurs when your oracle client is not in the PATH of your computer. Make sure that the PATH environment variable contains

问题 We have a sqlserver (WinForms) application that is deployed with ClickOnce that talks directly to the database. If we are forced to port it to oracle, can ODP.NET be used with ClickOnce.

Most users access the system var an Asp.net application, or a WinForms (clickOnce) application that talks to a

问题 I am trying to configure connection pooling for my .NET application using ODP.NET version 2.111.6.20. The database is Oracle 11.1.

It should never get higher
