Cannot Get Connected To My SQL Server
Mar 23, 1999
When I try to connect to my SQL server I get the following error.
Microsoft SQL Enterprise Manager
A connection could not be established to MLM1-[SQL Server] Cant allocate space for object 'Syslogs' in database 'tempdb' because the 'logsegment' segment is full. If you ran space in syslogs dump the transaction log. Otherwise use ALTER DATABASE or sp_extendsegment to increase the size of the segment.
Ok, I am not up on SQL so I'm not sure how to dump my tempdb database. I have a coworker that has only done this sort of thing in the Enterprise Manager and we can't get there. So how do I do this and make sure that I don't blow away any data? Also if I do dump my tempdb will this cure my problems and how do I avoid having this happen again?
Any help would be greatly appreciated,
Jeb

I am using SQL Server 2005 Express + SP1 on a Windows Small Business Server(SBS) box. The SBS is connected to a client thru LAN.
Following are what I gave as IP address and DNS on the server:
IP: 192.168.16.2, subnet mask : 255.255.255.0, Preferred DNS server: 192.168.16.2, Default gateway and Alternate DNS Server blank
On the client, I have,
IP: 192.168.16.4, subnet mask : 255.255.255.0, Preferred DNS server, Default gateway and Alternate DNS Server blank
I can ping and connect to either of the machines.
If I do a sqlcmd -S "tcp:servernameINSTANCE,port", I get the following error message:
HResult 0x80090304, Level 16, State 1
SQL Network Interfaces: The Local Security Authority cannot be contacted
Sqlcmd: Error: Microsoft SQL Native Client : Cannot generate SSPI context
If I do a sqlcmd -S "tcp:192.168.16.2INSTANCE,port", it connects to SQL Server.
I have the Windows Firewall ON. If I Off the firewall, I do not have any problem at all.
I included File and Printer Sharing, sqlsvr.exe in the Exception list of the Windows Firewall.
Any help to solve the issue is appreciated.
Thanks.

I have a query that finds all SPID's connected to a particular database:
select d.name, p.*
from sys.databases d join sys.sysprocesses p
on d.database_id = p.dbid
where d.name = 'my_db'
But now we have a new rule that we should not use outdated compatibility views, and one of them is sys.sysprocesses. I checked sys.dm_exec_connections/session/requests but failed to replace my existing code. The first two don't have dbid, the last one, requests, has it, but it selects only currently executing statements.

I have read that if I change "computer name" and then try to startup sql server it will recognize the changes automatically BUT you need to execute sp_dropserver and sp_addserver procedures too in order to set all thing right.But yesterday I tried it on a Personal edition on xp and after reboot sql server came up without any problem and I could connec it without executing sp_dropserver and sp_addserver! Was it a specific situation or no need to those SPs at all?

Recently I needed to find all processes connected to a particular database, let's call it Test_db. I have a simple query to find all connections to my database:
select *
from sys.databases d join sys.sysprocesses p
on d.database_id = p.dbid
where d.name = 'test_db'
But there was a process that was connected to another database like USE another_db_name; but was actually selecting from tables in test_db. Is it possible to catch such connections?

We have an information retrieval application in which there is a single connection to a database followed by multiple table open, read, and close commands. Response time is consistantly less than 1 second on a LAN.
When Internet connected (not VPN), the first table read is typically fast, but the response time becomes slower and slower after multiple table open, read, and close commands. There seems to be a considerable amount of handshaking based on monitoring of the router's status lights.

Hello all,
When I close a web form that has a connection to my SQL Server, I am not seeing the memory process close in task manager (of the SQL Server). I am using the "open late close early" theory of database connections. I am using the "close" method for my database connections. Is there any automated utility that will shut down these processes? I thought when the user was disconnected from the database, the memory process would automatically shut down.
Any suggestions, thoughts, or ideas?

I have a website I'm ready to test on the server it will call home. I just got connected to the remote SQL server that it will be using. As I've been creating the site, I've been using the default SQL Express set-up in Visual Studio. Is there a way to have Visual Studio create all those default tables, procedures, etc. OR is there a way to copy all of that stuff from the SQL Express running on my machine to the remote SQL Server 2005?

Does anyone know if this is a SQL Native Client bug? I've read a previous thread (posted back on Jan. 18th, 2007) about this error, but there are no replies. I am getting this error when I issue the sp_setapprole command using sqlexecdirect() ODBC api call. Is there any way to work around this? Or is there a fix to the SQL Native Client? The error 15002 message text states "The procedure sys.sp_setapprole cannot be executed within a transaction". This is on a new connection so there should be no transactions active at the time. Thanks in advance for any info anyone can provide on this.

Beginning this morning, when I look in Current Activity in our SQL 6.5 Server, all trusted user connections to my server are showing up under "SA".
We are running mixed security. Most of the connections are through ODBC. We have applied SP5a to SQL.
As far as I know, nothing in SQL has changed. From what others are telling me, nothing in NT or the network has changed.
Something is up. What am I missing? Where can I look?
Please help.

Hi
I spent the whole week trying to find a solution with a problem of authorization/access on a new website (aspnet2 + slqserver 2005)
The site was running well in the test environnement but once deployed the production site behavior was quite erractic. some clients run ok, others not and that changes for the same client with each session.
it appeared that the problem came from the access to stored procedures. sometime, theirs accesses were authorized sometime denied.
finally, tests showed that the client's userid was either aspnet or iusr_
by putting the same permissions on these 2 accounts, the problem is solved and all the clients are running fine.
now the question : for which reason the client connect randomly to one or the other of these 2 id ? is this normal ?
best regards

Hi everyone,
I have one Inventory system which is in VB6 and SQL Server 2000.
In my database there is table of users and userrights.
These are my application users. They are nothing to do with Windows users and SQL Server users. I am connecting to database using 'sa' login.
Now I want to display all my online users. I tried with @@SPID to manage their but not getting the exact results.
Thanks in advance.

Hi,
I need to be able to list all User connected to a particular database, after doing a bit of playing I have writen a simple view in the database to show this information which looks like
select spid, status, loginame, hostname, blocked, db_name(dbid), cmd from master..sysprocesses where db_name(dbid) = 'AutoCost2008
But my problem is that as this needs to be run from an application where the user is logged on as a standard user and therefore when this is run it only shows the current user, I am not sure what permissions I need to give this login to allow them to view all users connected to this database without giving them full Admin permissions, can anyone please help.
Thanks,
Gavin,

Hi Everybody:
I'm writting an standar application in c# that comunnicates with a sql server 2005 in a mobile device. The mobile device is connected to the pc with an usb wire. In the sample I've made, I've inserted in the form main a datagridview. I go on the wizard to select the data source. I choose a Microsoft SQL Server Mobile Edition data connection. The data source is tge activesync mobile device. I create a new database in the mobile device called test.sdf. The wizard has a button to check the conecttion and it rules. A new connection appears in the server explorer. I add rows through a query. I build the solution and no problem, but when I start the debug session an sqlceexception occurs: Data Source not found. In the database connection that the project has created the connection string is: Data Source ="Mobile Device est.sdf";
I didn't write any code. I just went on the wizards. All the code has been inserted by visual studio 2005.
Any idea?

I have a web application that runs on IIS on Windows XP professional. I have reached the max number of connections to the IIS website. So, I tried the approach of disabling HTTP Keep-Alives.
All is fine and dandy until my Business Intelligence Studio report project attempts to set the parameters for a report using report viewer at which point I get the following error message:
"The request failed with http status 401: access denied."
How can I fix this? I have posted this over at the asp.net forums, but I figured I would check here to see if anyone else has solved this problem.

The following looks very much like the problem reported for the JDBC driver.
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=688897&SiteID=1
https://connect.microsoft.com/SQLServer/feedback/ViewFeedback.aspx?FeedbackID=191767
----------------------------
I've written a small VB .Net app using Visual Studio 2005 to test mirroring from the client's perspective.
I have a button that does the following: 1) opens a connection to a sql 2005 database (SP2), 2) uses the connection, 3) closes the database connection.
After running this code, but while the client app is still running, I failover the database to the failover partner.
When click my button again, I get the following error: "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)". Checking the Event log on what is now the mirror, I see a string of "18456 Login failed for user 'testuser'"
If I close the app and launch it again, it does the right thing (and connects to the new primary). Also, instead of closing/re-opening the app, if I wait long enough (e.g. 10 minutes), then try again, it connects successfully to the new primary. Finally, instead of closing/re-opening the app if I tweak the connection string (e.g. change the application name) then try to connect again, that also works.
Based on articles I've read online, I've disabled the connection pool in my connection string, but that didn't solve my problem (although I'm getting a different error than if pooling is on).
Here is the connection string I am using:
Data Source=DB1PACS,12345;Failover Partner=DB2PACS,12345;Pooling=False;Initial Catalog=PACSTest_Client;Integrated Security=No;User ID=testuser;Password=*****
Here is the code snippet that I run before and after the failover. Based on the fact that I'm not using Pooling, the ClearAllPools() if overkill. Any help would be appreciated; I've been researching this for days without luck.
I can keep clicking the button that runs this code, and it keeps failing. If I wait long enough (e.g. 10 minutes) and then click the button again, it works. Or I could quit/restart the app, or tweak the connection string.
Dim TestClient_Connection As New SqlClient.SqlConnection(txtConnectionString.Text)
If Me.DataGridView1.Rows.Count > 0 Then Me.Test_ClientDataSet.Clear()
Try
TestClient_Connection.Open()
Me.User_TTableAdapter.Connection = TestClient_Connection
Me.User_TTableAdapter.Fill(Me.Test_ClientDataSet.User_T)
TestClient_Connection.Close()
TestClient_Connection.Dispose()
SqlConnection.ClearAllPools()
Catch sqlex As SqlClient.SqlException
txtErrorMessage.Text = "Error State: " _
+ sqlex.Errors.Item(0).Number.ToString _
+ " Message: " + sqlex.Message
End Try
Similar to the JDBC driver article I mentioned, when using the connection string above (where DB1 is the principal and DB2 is the failover partner) if DB2 is the actual principal when I initially query and close the database connection, then after failover to DB1 my application reconnect just fine.
Thanks
