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?
View 0 RepliesWe 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?
When trying to open the log shipping status report, I get an error: user must be in the master database. The jobs appear to be running correctly.

View 2 Replies View RelatedI need to create a script that adds an incrementing suffix to two columns, but restarts based on the value of another column. I found a similar question in the SQL Server 2000 forum, but it doesn't quite fit and also I'm working with SQL Server 2008 R2. The code below both creates a table with test data and tries to carry out the task. If you run this, you will see that the VISITNUM column has a value of UNS in row 4, UNS.1 in row 5 and UNS.2 in row 6. In row 7 it's V200, then in rows 8 and 9 it's UNS.3 for both. The same suffix gets applied to the VISIT column, but of course if I can solve this for VISITNUM then adding the suffix to VIST as well will be easy.
What I need is for row 8 to have UNS and row 9 to have UNS.1. In other words, any time the VISITNUM is UNS several times in a row, I need to add that ".X" suffix, but if a row has something other than UNS, I need to start over again the next time it's UNS again.
CREATE TABLE #testing(
KitID varchar(20),
SubjID varchar(20),
VISIT varchar(60),
VISITNUM varchar(20),

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!

Hi folks,
That is the question: how many concurrent connections support Microsoft SQL Server 2005?
Thanks in advance,
Javier.
Standard costs 2000 euros approx (5CALs)
Enterprise costs 40000 euros apprx
Standard only supports 2GB or RAM
How many concurrent users do you think standard edtion can handle in a Dual Xeon 2.8 with 2GB ram ?
Enterprise is very expensive. sucks that standard can't handle more than 2GB Ram
I am STIGing a database and have to create a trigger that will stop any connection from occurring after a certain limit has been reached. For example I set the concurrent connection to 50 so I need a trigger that will stop any connection from all logins happening after 50.
The STIG info:
Rule Title: SQL Server must limit the number of concurrent sessions for each system account to an organization-defined number of sessions.
STIG ID: SQL2-00-000100
The below triggers works, but for only the one login, so how can I have it include all logins for that SQL instance.
CREATE TRIGGER connection_limit_trigger
ON ALL SERVER WITH EXECUTE AS 'login_test'
FOR LOGON
AS
BEGIN
IF ORIGINAL_LOGIN()= 'login_test' AND
(SELECT COUNT(*) FROM sys.dm_exec_sessions
WHERE is_user_process = 1 AND
original_login_name = 'login_test') > 3
ROLLBACK;
END;
If applicable, what's the limit on concurrent queries supported by SQL Server 2005 Express? Also, if there's a limit, does next connection after the max errors out or merely queues up?
Thanks,
Phillip
I am researching this and playing with using the syss.sysprocesses view and counting the dbid column. I would most likely want to store this information in a table with a date/time stamp because we really want to track our concurrent users during the day for awhile. Do you have any neat tricks in getting this done? Is there a DMV or Information_Schema view that could be used to accomplish this task? I found the following code on the internet:
SELECT DB_NAME(dbid) AS DBName,
COUNT(dbid) AS NumberOfConnections,
loginame AS LoginName,
nt_domain AS NT_Domain,
nt_username AS NT_UserName,
hostname AS HostName
FROM sys.sysprocesses

There are a series of traces of transactions for essentially the same units of work. Each includes a retrieving the same table "Select" from the database. The first 4 transactions ran concurrently. The last one ran about 7 minutes later with no other concurrent transactions.
The elapsed times for the database accesses for each of the first 4 is significantly higher than the last one.
Can you think of any database optimazation that might improve this?
Are there any utilities available than can be used for stand-alone testing of SQL Server database performance?
E.G. they would measure response time for reading/writing large/small amounts of canned data once/multiple times with concurrent/nonconcurrent access.
SQL Server Database is on 2000.I am not sure about the ISOLATION level in the Java code.
Basically I am new to SQL Sever....Please ans the above questions and provide me the direction to proceed on these questions

View 3 Replies View RelatedWhile 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've a SQL server that intermittently restarts itself mostly during. Its a SQL Server 6.5 SP4 running NT 4.0 SP6. It really has no rhyme or reason to it happening. The are no indications in either the SQL or the Nt events logs.
Has anyone heard of this?

Hi,
I have a linked server set up to a proprietarty temporal DB through an OLEDB provider. From time to time and for various reasons the OLEDB provider crashes with "Error 7302 Could not create an instance of OLE DB Provider 'IhOLEDBProvider.iHistorian.1'. OLE DB Trace [Non Interface Error: CoCreate of DSO for IhOLEDBProvider.iHistorian.1 returned 0x80070008"
Up till now, to re-initilize the connection we have just restarted the SQL Server service. However, some automated processes are now feeding data into this server and more users and have started coming online so restarting for this issue has become a big deal.
Getting the OLEDB provider sorted out isn't an option at present so my question is:
Is there a way to re-initalise a failed linked server other that restarting the SQL Service?
Thanks,

Hi,
I have SQL server running on windows Adv Server 2000. Since last couple days whole computer restart every one hours. Only thing I remember doing was to shrink database db size is 200+GB.
How can I fix this problem.

Hi,
I've got a table with a column that contains the status of available licenses to the user, i.e. they are either in use or are available. If the server goes down, then when it is restarted I need to make sure all the rows in this column describe each license as being available.
So the question is how can I ensure data in a table is, if you like, initialized, each time the server is restarted? Is there a system defined stored proc or trigger than is executed when a server is restarted?
Thanks.
Hi...
i hv a database (sql server 2000) where i got locking on many tables and my application was down.
I restarted the sql server and the application was fine but after five minutes the same locking issue started happening. I did a index rebuild the next time on all indexes and everything was fine.But i cannot relate how locking occured and why it was not after index rebuild.Can anyone shed some light on this or anyone had similar experience... cos i cannot figure out a way on this.
Thanks in advance

View 1 Replies View RelatedHello everybody
I setup Sql agent for autostart with sql server and autorestart if stoped
but after rebooting NT or after stoping SQL server it never starts ,I have to start it manualy
Where to look for problem ?
I have an old application to maintain that uses CDatabase to connect to SQL Server. If SQL Server is stopped and restarted, such as in a cluster failover (i.e. move group), then the CDatabase connection needs to reconnect. It seems that it's not capable of doing this on it's own so I need to check the state some how. Various methods, such as IsOpen, seem to be useless as far as determining if I have a "good" connection.
Any thoughts?
@@servername sometimes returns NULL depending on how you have been messing around with replication and various other settings.
The simple solution offered to fix this is to delete the entries in the system tables and sp_addserver 'servername','local' and then restart the SQL service.
This is fine but what do you do in the situation where the SQL server is a 24/7 production box ? Does anyone know of a method / hack to fix this without stopping the service ?
Thanks

We were trying to restore our production server db backup in test server over LAN (due to space shortage on test server) . Test server hanged and did not respond for abt more than 15 hours (backup file 40 GB ) . The we restarted the server (resetting the power button) . Now it's showing the status 'Restoring' . According to me it's not doing anything (as seen in task manager workload ) . So how can I go ahead with checking the db .
Due to 'restoring' status I get following error
------------------------------------
Msg 927, Level 14, State 2, Line 1
Database 'envdb' cannot be opened. It is in the middle of a restore.
----------------------------------
Hi All.
Our inhouse app used to run on a SQL2000, but we've recently moved it to 2005.
The move was done by way of backup and restore (it was on a whole new server).
After the move, an odd problem showed up: once in a while, the server seems incapable of finding/using its indexes: everything starts working slowly, until I run a maintenance plan that rebuilds its indexes etc.
In the database/server all relevant options seem to be ok (auto update statictiscs etc.), and my conclusion that it doesn't use its indexes comes from the fact that:
* it gives the results from certain select statements in a totally different order (although the set of rows is the same),
* performance is (all of a sudden) very slow (seconds turning to minutes!!)
This happens:
* at least after a reboot of the server
* sometimes just in the middle of the day
The only way I've found to solve the matter, is by running the maintenance plan to rebuild the indexes, but sometimes this only seems to work the second time.
Does anybody share this experience, or know what to do about it?
Thanks,
Nick.
