A request to establish a connection with transaction manager denie

A user has reported the message "A request to establish a connection with the
transaction manager was denied". The code is at this point attempting to
START a transaction. So far I have been unable to duplicate this, though the
user has been able to get through this code in the past. Of course, no known
changes.
What causes this particular message?

Brad AshforthHi Brad
This looks like a XACT_E_CONNECTION_DENIED error, which might be thrown if
you already have the maximum number of connections.

level? Our application is designed such that we do not make use of nested
transactions. We have a "transaction" routine that is called with either
"Begin", "Commit" or "Rollback", and if the routine is called with "Begin"
(as it was in this case), we first execute a commit (in case a transaction is
pending that was not committed or rolled back) and then do the BEGIN. Of
course, if when we issue the commit if there is no pending transaction, we
get an error ... but that is trapped for and ignored if we are trying to
begin a new transaction.
So, that said ... there should only be one transaction active for the
application at any given time and if by chance we try to start another one
the code automatically commits the first one before starting the 2nd one.
Is there a way to query how many connections there are?

Thank you for your posting!
I would like to know some detailed information:
1. Does your customer use Distribute Transaction? If so, does the DTC
services start?
2. Are there any error log in event log? If so, please post it here.
3. What's the SQL Server Version and the Server OS version?
Please let me know the result and so that I can provide further assistance.
Sincerely,

1). No, the customer does not use Distributed Transactions (at least not to
their knowledge)
2) No errors in any of the event logs on the SQL Server box
3) From SQL Query Analyzer @.@.Version returns 8.00.760, from a cmd shell VER
returns 5.2.3790 (Windows Server 2003 Enterprise Edition)
Please note that this error occurred in an acceptance testing phase, not in
production.

Checking @.@.TRANCOUNT will tell you whether a transaction is in progress.
Using a commit that when a transaction has not begun will cause an error:
Server: Msg 3902, Level 16, State 1, Line 1
The COMMIT TRANSACTION request has no corresponding BEGIN TRANSACTION.
Which you can easily avoid.
I don't think this is the cause of the issue! Do you reference any other
databases either in your stored procedures or triggers? Are you using
multipart naming conventions? Are you enquoting your names using square
braces []?

We had not known about @.@.TRANCOUNT and agree that it makes more sense to
check this instead of trapping for a known error that is likely to occur (on
the other hand, isn't that what TRY/CATCH is supposed to do?) Anyway, I also
agree that this is not the likely cause of the error I originally posted a
question about.
We do not reference other databases, and in most (99%?) cases do not use
fully qualified table names. This is because most tables are in the DBO
schema and do not get to the user's own schema ... each user temp table (for
reports, etc) are in their own schema. In most cases the object names follow
standard conventions and should not need braces. This is also not an error
that is easily repeatable. It has been seen before but have had trouble
duplicating it.
Thanks,
Brad

Prefixing with the schema name should improve performance and caching.
If this problem is periodic you are not going to know for certain that you
have cured it!! How often does it occur? Does it mainly occur after a re-boot
or a high load levels? I know you have checked the Event logs what about the
SQL Server log?
If MSDTC is currently running try switching it off, as this should not
effect your application if it is not being used!!

As the application is used in multiple environments, we have no control or
knowledge of the deployment and don't code the fully qualified object name,
currently it would take a LOT of rework to do this. Is the performance
improvement enough to make it worthwhile?
Yes, periodic failures are a pain to diagnose. The problem occurs RARELY (I
think it has only happened once or twice in a deployment. Not all deployments
have seen the problem and the total number of occurrences is certainly less
than 6 or 7. Rebooting does not seem to be the issue, nor does load level (no
reboots either before or after the error). I currently do not have access to
the SQL Server log. Will try to obtain it.
MSDTC is not used by our application, but if a deployment decides to house
multiple databases on the SQLServer, wouldn't it be better to leave it on?

Using the schema name should not effect the deployments as this should be
constant, two part naming will help to varying degrees, depending on what
specification the server has and the load it takes. In general it is good
practice to do this and is usually easier to implement though of coding
standards and QA than retrospectively.
If you share the server with other applications you would need to make sure
that they don't use MSDTC, but any service on the server that is not being
used should be stopped as they will take up resources. If you stop this
service then it may make it easier to highlight something wrong with your own
application.

databases that require MSDTC but the server DID have the service as auto
start. I've set it to manual and stopped the service. We'll keep checking to
see if it happens again.
Thank you,
