This is all happening due to one filter condition in LINQ :
var list = (
from c in _crmRepository.Query<Contact>()
join cn in _crmRepository.Query<Connection>() on c.ContactId equals cn.Record1Id.Id
join a in _crmRepository.Query<Account>() on cn.RecordId2.Id equals a.AccountId.Value
where c.StateCode.Value == (int)ContactState.Active
&& cn.StateCode.Value == (int)ConnectionState.Active
&& c.BirthDate != null
&& a.ace_NetworkClient.GetValueOrDefault()
select new ReturnedCustomerDataClass
{
AccountId = a.AccountId.GetValueOrDefault(),
ContactId = c.ContactId.GetValueOrDefault(),
aceContactId = c.ace_ContactID,
<<<<<<< Many Other Fields>>>>>>>>>>>
}
In Where Clause you can see a filter a.ace_NetworkClient.GetValueOrDefault().
When I am removing this filter my query is not responding and being stuck. Can any one suggest me what is going wrong if I am removing filter && a.ace_NetworkClient.GetValueOrDefault() {ace_NetworkClient is a boolean field}.
In my result I wanted both customer for whom ace_NetworkClient flag is true or false thats why I removed that existing condition, getting proper result for local Org. but failing in production org due to large data.
Thanks
I have used Entity Framework 5 for Oralce Database of web-based application. Sometimes (rarely happens), error "ORA-00933" occurs but when I restart the webapp, it gets work again.

There is a bug in the provider for Entity Framework from Oracle.
Seems like the Oracle.ManagedDataAccess.EntityFramework.SqlGen.SqlSelectStatement.Top_s is the culprit that gets borrowed by a parallel query. This should either be thread static (quick hack) or moved to some contextual state (proper fix, e.g. to SqlGenerator).
https://community.oracle.com/thread/3728543
No answer from Oracle support. That being said, there is a new version of the nuget package : 12.2.110. You may give it a try and check if the issue is fixed.
I'm having something that is occurring intermediately (like <1% of the time), that I have no idea how it is possible. I have a plugin registered on the Post Operation of the Qualify Lead event, and have overridden the Qualify Button to execute a Qualify Lead request, setting the CreateAccount, CreateContact, and CreateOpportunity values to false. The plugin then creates the Account, Contact and oppotunity, as well as 4 other potential custom entities.
Below is the relevant code:
protected override void ExecuteInternal(ExtendedPluginContext context)
{
var createdEntities = context.GetOutputParameterValue<EntityReferenceCollection>("CreatedEntities");
var initiatingUser = context.SystemOrganizationService.GetEntity<SystemUser>(context.InitiatingUserId, u => new { u.new_RelatedEmployee, u.FullName });
var initiatingUserEntityRef = initiatingUser.ToEntityReference();
var lead = RetrieveLead(context);
CreateAccount(context, lead, initiatingUserEntityRef, createdEntities);
CreateContact(context, lead, initiatingUserEntityRef, createdEntities);
CreateLocation(context, lead, initiatingUser, createdEntities);
CreateSystemPullJob(context, lead, initiatingUserEntityRef, createdEntities);
CreateInstallJob(context, lead, initiatingUserEntityRef, createdEntities);
CreateOpportunity(context, lead, initiatingUserEntityRef, createdEntities);
CreateOpportunityProducts(context, lead, initiatingUserEntityRef, createdEntities);
UpdateLead(context, lead, initiatingUser, createdEntities);
}
private static void CreateAccount(ExtendedPluginContext context, XrmLead lead, EntityReference initiatingUser, EntityReferenceCollection createdEntities)
{
if (lead.CustomerId != null)
{
context.Trace("Account already exists for Lead. Not creating Account.");
return;
}
context.Trace("Creating Account");
var account = context.SystemOrganizationService.InitializeFrom<Account>(lead.ToEntityReference(), TargetFieldType.ValidForCreate);
account.OwnerId = initiatingUser;
account.ModifiedOnBehalfBy = initiatingUser;
account.CreatedOnBehalfBy = initiatingUser;
account.Id = context.SystemOrganizationService.CreateWithSupressDuplicateDetection(account);
lead.CustomerId = account.ToEntityReference();
createdEntities.Add(account.ToEntityReference());
}
private static void CreateInstallJob(ExtendedPluginContext context,
XrmLead lead,
EntityReference initiatingUser,
EntityReferenceCollection createdEntities)
{
context.Trace("Creating Install Job");
var job = context.SystemOrganizationService.InitializeFrom<new_job>(lead.ToEntityReference(), TargetFieldType.ValidForCreate);
job.new_jobname = "New - Install";
job.new_CustomerId = lead.CustomerId;
job.new_LocationId = GetLocation(lead, createdEntities);
job.new_JobTypeEnum = new_JobType.Installation;
job.OwnerId = initiatingUser;
job.ModifiedOnBehalfBy = initiatingUser;
job.CreatedOnBehalfBy = initiatingUser;
if (lead.new_PreviousLocationId != null)
{
// Set prerequiste job to system pull job
job.new_PrerequisiteJobId = createdEntities.First(e => e.LogicalName == job.LogicalName);
}
job.Id = context.SystemOrganizationService.CreateWithSupressDuplicateDetection(job);
createdEntities.Add(job.ToEntityReference());
}
The account is created, added to the lead.CustomerId, and then used to add the relationship to the location upon creation.
According to the stack trace, the error happens on the Creation of the Install Job, (even though the Contact already was created, and references it as it's ParentCustomerId)

I only see two possibilities, that the account wasn't created to begin with (seems unlikely since the contact creation was successful) or that the account is deleted after contact creation, but before Install Job Creation (but I'm not aware of anywhere that we perform deletions, and I don't think you can have a deletion of an entity in a transaction, from outside the transaction...)
Ideas?
Can you verify that the "missing account id" is the id of the account that was supposedly created?
If you query the db for this account after the error occurred, I guess it gets no hit?
Did you check "double click bug"? Issuing the QualifyLead twice "simultaneously" could of course lead to interesting effects, if there is possible SystemOrganizationService bleed between the two executions.
(Tried to make this a comment since it's technically not an answer, but it was too long.)
What happens if you comment out creation of the install job? Does everything else work correctly? Account gets created?
Another thing to check would be to query for the account after each of your create methods execute. Would help you narrow down when the account disappears.
Also, in regards to your note about deletions from outside the transaction being prevented, my understanding of how transactions work is as follows. What you suggest would be true if the delete came from something that creates its own transaction (an async plugin, say). But if the delete came from some synchronous plugin on create of contact, for example, then that plugin would also be running in the transaction. If that is true, then it would be allowed to delete the account.
Not an answer either but too long for comments
So if you're saying it a) happens intermittently and b) there is no other logic that could be deleting the account, I think the only conclusion is for some unknown timing reason, the create of installjob gets ahead of the account being visible to it. No clue why this would happen but again, to narrow things down you could catch the exception and not fail the transaction. This would at least tell you if the account actually did get created ok. If that's the case and the root cause of the timing issue can't be found, you could only try the installjob create if you are sure you can retrieve the account. All workarounds until more elimination of variables can be done.
Another thought is could it be security-related? That account does not exist message may really mean account does not exist for you. Seems odd if the plugin context user created it but maybe other security factors involved?

I have a hard time trying to fix the problem. I follow everything and even redo it just to make sure I got it right. I don't think I miss any steps. But there is something wrong. If I run the whole sample code, everything works fine.
Any help is appreciated.
Thanks,

EDIT:
It was really frustrating for a simple thing that lead to an error like this.
#mmeasor, I just saw that error as well. It cannot connect to database. So that lead me to check the connection.
What happen was that at first I used this connection string:
So EntityFramework created a database file ContosoUniversity1.mdf in here like C:\Users\Office\ContosoUniversity1.mdf. But then I want it to create another one and use that instead and this time I want it to be in the program App_Data\ folder instead.
So I modified the web.config file to:
I thought if I do that, EF will create a new database for me in the \App_Data\ folder and link to that instead of the old on in C:\Users\Office.
I was so wrong! that was when I start getting the error posted above. And I cannot find what causes the problem.
With the second web.config, I tried to copy the database file to the App_Data folder, but that still doesn't work.
Now I use the first connection string and it works fine.
So now the question is: How to make the program links to database file in the \App_Data\ folder instead?
Thanks,

I had the same problem in trying to change location of Conosto University tutorial database from User folder to App_Data folder. John Locke keyed me into the idea that it may have something to do with having to change the name of the database.
Change name slightly of database named in the web.config file (This works inconsistently, but does work consistently inconsistently. If I had to test this again...and I'm sure I will at some point...I would stay away from reusing names - i.e. don't toggle back and forth between two name preferences (e.g. database1 and database2 back to database1 - I would use completely novel names e.g. databse7...database8...database9 - get name away from previously used names)
I also had luck, once a database was created with the name I didn't want, changing the database name to what I wanted it to be and matching that name in web.config (i.e. I was able to create a "database3.mdf" file successfully and then changed it in the OS to what I wanted - "database1.mdf" and matched the web.config file to database1 and it connected up on the first try)
I had this problem for days ("An exception of type 'System.Data.DataException' occurred in EntityFramework.dll but was not handled in user code") and I tried everything since changing the connection string to many different methods I saw on Internet questions and answers,
My solution?...
Created a new proyect with another name, and it saved me.
Here EmployeeDetail is a table name and Employee is a model name. And
ID,Branch, Salary and UID are table fields:
public ActionResult Index()
{
List<EmployeeDetail> employees = context.EmployeeDetails.ToList();
List<Employee> emp = new List<Employee>();
foreach(EmployeeDetail item in employees)
{
emp.Add(new Employee
{
ID=Convert.ToInt32(item.ID),
Branch=item.Branch,`enter code here`
Salary=Conve`enter code here`rt.ToInt32(item.Salary),
UID = Convert.ToInt32(item.ID),
});
}
return View(emp);
}
view page code
<div style="font-family:Arial">
<h2>Index</h2>
<ul>
#foreach (var emp in Model)
{
<li>
#Html.ActionLink(emp.Branch, "Details", new { id = emp.ID });
</li>
}
</ul>
</div>
We have recently configured SQL SERVER 2005 reporting server and it works when I go to http://<servername>/reportserver. But when I want to access http://<servername>/reports, I am getting the error.
"The request failed with HTTP status 400: Bad Request"
After going through few articles online about how to fix it...
I have tried changing some code in the RSWebApplication.config file.
<UI>
<ReportServerUrl>http://<servername>/reportserver</ReportServerUrl>
<ReportServerVirtualDirectory></ReportServerVirtualDirectory>
<ReportBuilderTrustLevel>FullTrust</ReportBuilderTrustLevel>
</UI>
But it did not work. Can anyone please help? Thanks!
here is the log...

Look like a security issue. Might want to examine this MSDN article there seems to be number of possibilities. Let us know if any of them work.
