Login Name Shows Up As Blank For Certain Sessions
Aug 29, 2011
When I probe sys.dm_exec_sessions (joining with other DMVs to get active-session info) I get the login_name column to be blank for a certain session.
Yet, for the same spid, the Login shows up properly (not blank) when I execute "sp_who2 active".
It also shows up properly in sys.sysprocesses.
What could be the reason for the faulty output of sys.dm_exec_sessions ?

I have created a report with a stored proc which takes a parameter whose default value is null. Now when I run my stored proc in Enterprise Manager without any params I get 4 rows otherwise with proper parameter I get 2 rows.
Now I set the params value to allow for Null and blank values. When I run the report if I provide parameter value it works fine but if i try to run it without any param it shows an empty report while the stored proc running without params shows 4 rows.
I have earlier sucessfully created reports where stored procs had 4 params out of which 3 where defaulted to null. And so I set the allow nulls, Allow Blanks values to be true for those params in Rep services. So when I selected value for 1st param and ran the report I got the desired report. But this time I have only one param which can be null. But its not working.
Thanks in advance.

I have a SQL Agent job that runs at 4:15 in the morning. The job has 5 steps, each step only runs if the preceding step succeeds. The second step, which calls an SSIS package that does the main processing, appears to finish as it goes on to the next step; however, when looking in 'View History' there are 2 entries for this step - the first one shows it as still running (Circled Green Arrow) but with a start and end time. The second entry says the job succeeded.
I have been seeing conflicts, such as deadlocks, with later jobs. I suspect this job is causing the conflicts - maybe the package is still running in the background instead of having actually completed?
what conditions a job step my be showing in the job history as both running AND completed successfully?

Return vresponse.Trim
* line 1)
rst = Nothing conn = Nothing
Exit Function
supposed to be *line 1) terminates the connection/session form SQL server. But when i check to the SQL Query Analyzer, there is still some connections related to this command. So when i run again this commands, it creates another connection. How can i terminate/end my sessions in SQL.

Hi all!
First of all, thanks to those who gave me suggestions to use sql-dmo
to generate sql scripts of a database.
I've found it extremely useful!
Here's my new problem.
I have VB code that connects to a database, extracts the schema
and generates the sql.
After some work with this script, I have some new scripts to alter the database and I have tried running these scripts in a separate project
with the ExecuteImmediate method of the Database object, which works well.
However, when I put this code into the first project, to reconnect to the database and execute the batch command,
I get SQL-DMO error -2147199229 (80045203)
...whatever that means..
Can anyone help me?
Thanks

Hi Friends,
We need a small suggestion regarding releasing the resources utilized before closing the session we established with the SQL CE database. To the best of our knowledge we are releasing the resources properly but still some how some resources get locked and we were not able to open a new session after closing the existing session.
Are there any functions or methods available to identify the existing resources, rowsets and other components who have connection with the existing session, kindly help us in this regard since we struck up mainly with this issue.
We work with EVC++ 3.0 and SQL CE 2.0
Thanks in advance.
Regards,
Sasi.

I have a process that seems to leave many orphaned sessions over a period of time. The software is by a 3rd party vendor and they can't seem to fix it. It is safe to end the orphaned sessions and I do that on a regular basis. My questions is: What is the best way to do this via T-SQL?
I can select the orphaned sessions by using a simple query on the sys.dm_exec_sessions table. How do I then run a kill command for each session_id from that query?
I appreciate any info/advice anyone might have!

Hey
I have a problem in controlling the report session.
I created a Reporting Model using SQL reporting Services 2005 with Forms authentication on which I implemented the security Filter based on the function GetUserID() to report only against data that belong to the login User, and I deployed the Model.
Using report Builder application I created a report that contain in the first column the user name (UserName) from entity €œUsers€?, and in the remaining columns data from other entities related to table users, I saved the report on the report server.
I logged in into report manager with user €œUser1€? and I ran the report, the result was the same as expected (in the first column €œUser1€? appeared and in the remaining column other data related to this user appeared) every thing went good
After that I logged in with the user €œUser2€? and I ran the report and here was the surprise the same data that appeared for "User1" appeared for "User2". but what was Expected is different data that belong to "User 2"
After some research that says that this problem may be caused by a session issue (the session created for the first user who enters the report server will remain for the other users that enter after him), I reset IIS and I logged in with €œUser2€?, and I ran the report the correct data for €œUser2€? appeared So it may be a session issue.
My question is:
Is there any way to control the session content and the session expiration?
Please note I used all the solution provided in my research such as URL parameter rs:ClearSession = true, and the Report Execution Options in report manager but non of this helped me.
I will be thankful for any one who could help me in this urgent issue.
Thank you
BOB

I'm using SQL server 7 on Win NT. I have Access 97 as a front end, with linked tables though ODBC to SQL Server. Everytime I open a table in Access, a session appears when I type sp_who2. I close that table in Access, but I when I type sp_who2 the table session is still present. Does anyone know a cause for this?
I am researching why sometimes when we close are queries and tables in Access we have sessions in SQL server that becomes orphans/ghost. I try to kill the session but can't, so therefore I have to recycle the database.
Any help would be appreciated.

I just have a simple question on font dependencies in reference to deployed reports. In my company, we run citrix presentation servers feeding terminal sessions out to users in remote areas.
My question is, in a terminal session, do the fonts used in the reports need to be installed on the users' local machine (who is connecting via terminal session) or is it enough to just have it on the servers feeding out the terminal session?
For example, we create a report with Arial Narrow font. Our servers hosting citrix presentation server did not have this font installed, so we installed this font on the servers (thus they're displaying correctly). Obviously the server hosting our reporting services has the font. Now a user connects to the server, is granted a terminal session, launches reporting services, report is generated with the correct font displayed, and finally prints the report.
Will the report print in Arial Narrow if the users' local machine doesn't have this font install? I remember reading somewhere that the fonts do not embed, hence the reason for installing the font on our citrix servers.
I realize this is kinda out of the scope of this forum, but perhaps someone on here uses terminal services and can answer this for me. I do plan to test this out when I get home tonight. I'd test it right now, but my computer at home isn't on therefore I can't remote home (plus wake-on-lan isn't configured) to do an actual test. Just thought I'd get some insights from other people.
Thanks in advance!

Hi
I have been looking at the new DMV's prefixed with dm_exec_....and found a limitation with them.
Books online says sysprocesses is replaced with sys.dm_exec_connections, sys.dm_exec_requests and sys.dm_exec_sessions. The problem I came accross is identifying any sessions connected to a specific database which were idle. This is the sort of thing you need to know if you tried to restore a database and it says the database is in use.
I wonder if this is a bug or by design?

Is there a way to find the max number of sessions that were on a sql server since its last restart? I know how to get how many total connections there were since last restart, and the current number of sessions, but not the max number of sessions that were running since last restart. Also, opinion on the optinum number of allowable sessions, or a good way to figure out the balance?

So I've been monitoring long-running transactions on a SQL Server that hosts a couple of vendor-supplied databases that look after our factory.Today I noticed a pair that have confused my Excel spreadsheet (that I've been using to analyze these transactions).So here's the weird thing that I spotted. Given this query:
SELECT p.spid, p.login_time, at.transaction_begin_time, datediff(second, p.login_time, at.transaction_begin_time) as [difference]
FROM sys.sysprocesses AS p INNER JOIN
sys.dm_tran_session_transactions AS st ON st.session_id = p.spid INNER JOIN
sys.dm_tran_active_transactions AS at ON st.transaction_id = at.transaction_id
[code]....
I had a look in the event log on the server, which had just been rebooted at around that time. It seems that the clock got changed on boot-up, with the size of it quite surprising. This meant that these processes were able to start their transactions *before* they logged on. Hopefully this doesn't cause any other weird problems.So I've requested an investigation about time synchronization on our virtualization hosts... and in the mean time, have set the SQL Server services to 'delayed start'.

The benifit of UPDLOCK is that it avoids deadlock in case both sessions run the below query at the same time.The table has clustered index on ID column
----session 1 --------
begin transaction
select * from a1
update a1
set id = 22
where id = 2
----session 2 --------
begin transaction
select * from a1
update a1
set id = 22
where id = 2
Now to avoid deadlock in the above scenario we should use (UPDLOCK) hint in the select statement.Now my question is that deadlock will be avoided in this case when both the sessions use UPDLOCK hint. If only one session uses UPDLOCk and other does not then there will be deadlock .For example session 1 uses UPDLOCK hint this will hold the U lock on the row, but the session 2 does not use this hint and apply shared lock on the same row. Now there will be deadlock when session 1 tries to update the record and is blocked by shared locks of session 2. same will be the case with session 2 and both will wait for each other and hence dead lock.so what steps can be taken to avoid deadlocks in this case. I do not want to use Snapshot isolation.

We have a big software that run a warehouse distribution center, written in .NET Backhand is a SQL Server 2008 R2 STD database.
Now, it seems there is a problem with the sessions not being properly closed after each call to the DB. Here is the message got form SQL:
DESCRIPTION:A new connection was rejected because the maximum number of connections on session ID 57 has been reached. Close an existing connection on this session and retry.
In the .NET code, connection is made with the following code:
If oConn Is Nothing Then oConn = New SqlConnection
If oConn.State = ConnectionState.Open Then oConn.Close()
With oConn
.ConnectionString = "Server=" & Server & ";Database=" & DB & ";User ID=" & User & ";Password=" & Pass & ";Connection Timeout=" & 5 & ";MultipleActiveResultSets=" & True
.Open()
End With
This code is called once, at the opening of the software
StoredProc are call with the code:
Try
oCmd = New SqlCommand
With oCmd
.Connection = oConn
.CommandType = CommandType.StoredProcedure
[Code] .....
So every Command is closed after execution, yet, they stay active in the SQL Server. Is there something I'm missing here?

We have a linked server configured on our SQL Server 2005 server that points to our iSeries. A step in a scheduled job successfully updates data in tables on the iSeries using an update query and the 4-part naming convention (job reports success and updates can be verified), but it appears to leave locked records and open connections on the iSeries. No open sessions showing in SQL Activity Monitor.
The linked server is configured using Microsoft's OLEDB Provider for DB2. Are there additional settings that can be configured on the linked server to prevent this behavior or is this an issue that need needs to be addressed on the iSeries? A timeout setting perhaps (not sure if this fixes the record locks though)?
Any help is greatly appreciated.

are sqlclr stored proc sessions running in the same SQLOS execution model (Running, runnable and suspended status, Runnable Queue and Wait List) as other types of sessions and therefore ending up in the same queues, contending for very similar resources (except maybe for memory type because of MTL's role) etc?...or do they get treated in a very different way?

We have SQL Server 2012 EE SP2 server that is getting hit by reports that time-to-time use up to 300GB of tempdb.
It's happening because our clients can use 'bad' parameters for some reports.
Is there a way to autokill sessions that overuse tempdb (for example, if a session uses more than 15Gb in tempdb)?
Killing can happen immediately or after regular check (5 min for example).
