How can many users share the same .adp front end, just like it as if it was a .mdb file? The problem I've ran was the following...user A logs in, user B tries to use the same .adp front end, but gets a message that is already in use therefore can't get in. Thanks in advance!
View 1 RepliesI am trying to simplify a query given to me by one of my collegues written using the query designer of Access. Looking at the query there seem to be some syntax differences, so to see if this was the case I thought I would import the database to my SQL Server Developer edition.
I tried to start the wizard from within SQL Server Management Studio Express as shown in one of the articles on MSDN which did not work, but the manual method also suggested did work.
Trouble is that it gets most of the way through the import until it spews forth the following error messages:
- Prepare for Execute (Error)

There does not seem to be any method of specifying a number of sessions, so I don't see how to get round the problem.
Does anyone know how I can get the import to work?
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.

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?

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?
While analyzing Process/Session Information in SQL Server Current Activity over the last several months on our ERP's SQL Server I have noticed that the number of sessions open starts at a very low number after a system reboot (150), then slowly grows as users login and system activity increases. This seems very normal, except that over the next few weeks the number slowly increases (3500) until we reboot.
After looking at the sessions closely many of them have login times and last batch times that are the same, which tells me that a connection was made, but nothing has really happened since. For example, many of the sessions were opened 5 days ago and the last batch run by these sessions were 5 days ago too. Most of them are have a last SQL command batch ran as “sp_cursorclose;1”, ”sp_cursorunprepare;1”, or ”sp_cursorexecute;1”.
Performance definitely degrades over time as the number of sessions increases, until we reboot. Also, you would expect to see this number of sessions decrease during slow times, but this does not occur. Could something be mistakenly leaving connections open?

I have a table with the following columns employeeSessionID, OpDate, OpHour, sessionStartTime, sessionCloseTime. I need to see how many users remain active per hour. I can calculate how many logged in per hour, but I am stumped on how to count how many are active per hour. I have a single table that stores login data. I have created a query that pulls out the only the data needed from the table into a temp table using this query. Also note it is possible that the sessionCloseTime is null if the device has not been logged out this would need to be counted a active.
TABLE NAME #empSessionLog Contains the time stamp data OpDate, sessionStartTime and sessionCloseTime.

can see how many sessions logged in per hour with the following statement:
SELECT
opDate,
FORMAT(DATEPART(HOUR, sessionStartTime), '00') AS opHour,
Count(*) AS Total
FROM #empSessionLog
Group BY opDate, FORMAT(DATEPART(HOUR, sessionStartTime), '00')
Order BY opDate, FORMAT(DATEPART(HOUR, sessionStartTime), '00') ASCResults:
opDateopHourTotal

Where I am stuck is how do I count the sessions that remain active per hour until the session is closed with the sessionCloseTime.
I created am inventory table with few columns say, Servername, version, patching details, etc
I want a tracking of the table.
Let's say people are asked to modify the base table and I want a complete capture of the details modified and the session of the user ( ) who (system_user) is actually modifying the details.
Hi,
Here is my code on how i connect to my database
Dim rst As New ADODB.Recordset Dim conn As New ADODB.Connection Dim vresponse As String ' On Error GoTo err_proc Try conn.Open(GetConn(getconnid)) Select Case getmode Case 0 'execute then return first field rst = conn.Execute(getsql) If rst.EOF = False And rst.BOF = False Then Try vresponse = IIf(IsDBNull(rst.Fields.Item(0).Value), "", rst.Fields.Item(0).Value) ' vresponse = rst.Fields.Count Catch ex As Exception vresponse = "Error :" + ex.Message End Try End If Case 1 'execute only If bTransactional = True Then conn.BeginTrans() End If conn.Execute(getsql) vresponse = "OK" If bTransactional = True Then conn.CommitTrans() End If End Select
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.
Thanks
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.

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

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 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?
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'.
I have a table EugeneTest(id_num, fname, minit, lname)where field "id_num" is type IDENTITY and has UNIQUE constraintLet's say 2 user execute this code at the same time:DECLARE @return integeruse EugeneTestINSERT employees( fname, minit, lname)VALUES( 'Eugene3', 'F', 'Josephs')SET @return = @@IDENTITYIs is not possible to get duplicated value in id_num column becuase ofUNIQUEconstraint, but is it possible the both user get the same @@IDENTITYnumber( for example, if @@IDENTITY is evaluated and kept somewhere in thebuffer before the data actually get written to the disk )Thanks, Eugene
View 5 Replies View RelatedThe 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 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?

It's happening because our clients can use 'bad' parameters for some reports.

Killing can happen immediately or after regular check (5 min for example).

Hi guys,
I've been developing desktop client-server and web apps and have used Access and SQL Server Standard most of the time.
I'm looking into using SQL CE, and had a few questions that I can't seem to get a clear picture on:
- The documentation for CE says that it supports 256 simultaneous connections and offers the Isolation levels, Transactions, Locking, etc with a 4GB DB. But most people say that CE is strictly a single-user DB and should not be used as a DB Server.
Could CE be extended for use as a multi-user DB Server by creating a custom server such as a .NET Remoting Server hosted through a Windows Service (or any other custom host) on a machine whereby the CE DB would run in-process with this server on the machine which would then be accessed by multiple users from multiple machines??
Clients PCs -> Server PC hosting Remoting Service -> ADO.NET -> SQL CE
- and further more can we use Enterprise Services (Serviced Components) to connect to SQL CE and further extend this model to offer a pure high-quality DB Server?
Clients PCs -> Server PC hosting Remoting Service -> Enterprise Services -> ADO.NET -> SQL CE
Seems quite doable to me, but I may be wrong..please let me know either ways
Thanks,

Is there a way to specify a MS Access table (or query object) in the select query of SQL Server.
Ex.:
