I am in the process to migrate an old BTS 2006 application in BTS 2016.
I have a problem with WCF-Oracle Adapter. When trying to connect the DB, it raises an exception. The problem occurs when I use the adapter for polling as well when I try to use it to read or update data; in few words, it's impossible to connect the Oracle DB with the adapter (connection with code is OK, so it's difficult to imagine an ODP problem).
I use BTS 2016, WS 2016, ODP 12.2.1.0 installed for 32 and 64 bits environment.
I tried almost all changes possibles in adapters options with no results.
I suppose I missed a step but which one ?
Obvious problems have been all checked (TNSNames, port, user/password, etc ....)
Exception stack :
*The Messaging Engine failed to add a receive location "xxxx_Receive_Location" with URL "oracledb://XXXXXXX.****.net:1522/YYYYYY.****.net/Dedicated" to the adapter "WCF-OracleDB". Reason: "System.NullReferenceException: Object reference not set to an instance of an object.

Problem solved after Oracle client installation and re-installion of ODP. It seems that the wcf-oracle adapter use unmanaged driver, and unmanaged driver needs Oracle client.
Try setting up a Receive Location from scratch.
Previously we've had issues when migrating bindings between BizTalk versions, where they have introduced a new setting in the Adapter and not set a default. Creating the port from scratch will ensure that it will set it to some value. You can then compare the new binding to the old, and identify the culprit.

I'm trying to get OS authentication setup for a WCF-Custom Oracle send port in BizTalk 2013 R2. I can connect to the Oracle db using OS Auth in SQL Developer (When logged in as my BizTalk service account) and Visual Studio can use OS auth as well so I know that the account is active and has the correct permissions in the Oracle Db. Unfortunately, the BizTalk adapter throws the following exception when I try to query the database:
The adapter failed to transmit message going to send port "MySendPort" with URL "oracledb://MyTnsName". It will be retransmitted after the retry interval specified for this Send Port.

If I change the user name from "/" to a local Oracle account and password, BizTalk can query the db just fine.
I have both the 32bit and 64bit oracle 12c clients installed with ODAC 2.121.2.0. The Oracle env variables are first in the system PATH variable and I've added a binding redirect to the Microsoft.Adapters.OracleDB.config file in BizTalk to reference the newer ODAC version.
Any help would be appreciated.

I am deploying a test rig as per the directions from http://msdn.microsoft.com/en-us/library/windowsazure/hh674491.aspx with the controller and agents hosted on windows azure. I have followed all the directions properly and my VS client is able to see the controller and agents. However when i execute a load test, the test remains in an pending state and I see the below error in the Controller's eventlog. My problem is similar to one found at: http://social.msdn.microsoft.com/Forums/en-US/windowsazureconnectivity/thread/4040619f-5667-4445-804a-84f37d823c9f/. Please help!

Based on the error message it looks like the controller is not able to talk to the agent. Have you set up a connect group as mentioned below:
"http://msdn.microsoft.com/en-us/library/windowsazure/hh674497.aspx"
Creating a Connect Group
The Connect feature of Azure allows you to create a Virtual Private Network. Members of the group can include on-premise computers as well as Azure role instances. For the Load Test solution, the Connect group allows communication between the test controller and the agents.
Attempted this as well, and couldn't get it to work. Ended up having to move the Controller into Azure as well.
I followed the documentation as far as what ports the agent needed, and opened those up in the Azure firewall. However, after doing a network capture, IIRC it also used some dynamic ports that weren't going to work to open up.
So I found that I had to move Visual Studio, the Load Agent Controller, and the Load Agents themselves all into Azure to utilize this in the cloud.
there is a very strange thing going on
i have a web site made in MVC 3 deployed in an Azure WebRole
it was running fine and originally was made in VS2010
now i use VS2012
i decided to make some minor changes and it appeared to be working but keeps break down at random intervals
this is what is happening
after random intervals i get this error ErrorCode<ERRCA0017>:SubStatus<ES0006>
after 2-3 minutes of getting this error sites appears to be working fine
i havent changed anything from the previous version of the site related to caching
this error does nt happens when i test it in staging or in local environment
no where in my code im accessing this cache programmatically
i have copy-pasted entire configuration as it is from the azure portal and i know it it correct because these are the same configuration settings that were working before
i just using Azure AppFabric Caching because i need to save sessions some where. so the only place it is ever mentioned is in my websites web config and as i have told all the configuration can be assumed to be correct.
this is the stacktrace if this can be of some help

There was an interesting blog post about this error over a year ago: Azure AppFabric Caching - ErrorCode:SubStatus : What to do?.
Before intializing the DataCacheFactory modify the
DataCacheFactoryConfiguration.ChannelOpenTimeout of the
dataCacheFactoryConfiguration instance that you are using to a larger
value of 2 minutes. (can't use configuration to set the value, since
20 seconds in the allowed limit) . Also, this recommendation is only
for debugging purposes and ideally should not be needed in production
environments. This lets the underlying layer to respond back with the actual error
that occurred. Now, if you check the inner exception, you should see
what caused the request to fail.
Please follow these steps to find the inner exception which will explain why the request fails.
Note: If this is caused by a transient fault, you should consider using the Transient Fault Handling Application Block (which also supports AppFabric Cache) in order to implement a retry policy.
When connecting to oracle server from .NET application using ADO.NET for oracle, even if i closed the connection, the connection remains inactive at the Oracle server, so new connections could not be established because of the sessions per user limitation, is there is any way to make sure that all connections are closed? from Oracle server or from .NET application.
Thanks in advance
Could it be the connections stay open for a while due to connection pooling? Can you please paste some code showing how you close the connections? Also are you using ODP.NET or the Microsoft supplied classes?
You could try turning connection pooling off (add ;Pooling=false to the connection string in ODP.NET) to see if your issue is caused as a consequence of using it (just be aware that creating a new physical connection to the DB is an expensive operation, so you probably actually don't want to turn off connection pooling permantly).
Something similar to:
using (OracleConnection connection = new OracleConnection(connectionString))
{
OracleCommand command = new OracleCommand(queryString);
command.Connection = connection;
try
{
connection.Open();
command.ExecuteNonQuery();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
