How To Check Number Of Active Connections In SQL Server?
Jan 23, 2002
Hi All
How to check number of active connections ?
I know two ways of doing it ..
1. run sp_who2
2. in Current Activity in Enterprise Manager ..
If what ever number I am seeing is the Active Number of Connections ..then
I am facing a problem here ..
In My serevr I have 75 Users licenses are configured for Per server option ..
Through a Java aplication when Developer tried to capture any SQL server Connection it says following error ..
Details :
[MERANT][SQLServer JDBC Driver][SQLServer]Login failed. The maximum simultaneous user count of 75 licenses for this 'Standard Edition' server has been exceeded. Additional licenses should be obtained and installed or you should upgrade to a full version.
If I see from Sp_who2 and Current Activity , I can see only 37 Connections ...?
Why is so .. If I am having 75 configured and 37 live in sp_who2 ..why I am getting that error message ?
Is there other way to see Actual Number of Connections made to server ?
Hi all, When I detach a SQL Server database, I see the following information: Connections using this database: 5 Where are the connections from ? How can I check ? Please help me ! Thanks
Hi. I have to buy a license for MS SQL Server 2000 and I need to know how many active connections I will need. I could try by running the application with multiple users and see how many connections there are.
The questions is: How can I know the number of active connections to the Server?
we have roughly 22 people connected to one database. But after a while, their applications begin to drag due to in and out communication with the server. When i check the active connections on the sql server, some times i see 157 active connections, please how to i set a timeout or connection interval close, so as reduce the heavy load being put on the server. Or how can i automatically close connections when they get higher than 50 connections.
could somebody please let me know what is the maximum number of simultaneous users/connection per single SQL Server 7.0 box? Licenses are not the issue here, rather the number of physical connections supported before another server needs to be purchased.
Another variation of this question would be what's the highest number of databases that 7can be created on SQL 7.0 server and what is the highest number of physical connections supported per database? Again, licenses are not the issue. Thanks a lot in advance.
We just installed SQL service pack 4. I am now finding that when doing a sp_who2 active, there are a lot of connections that are blocked by itself. The common factor is they all have a status of 'sleeping'. The strange thing is that even though it shows the connection is blocked, it is in fact not and will still return results. Below is a snapshot of a portion of what the sp_who2 active returns:
SPID Status Login HostName BlkBy DBName 53 sleeping sa TRACKER 53 dbABC 58 sleeping sa TRACKER 58 dbCDE 64 sleeping sa TRACKER 64 dbSTA 66 RUNNABLE User12 PC24 . master 70 sleeping User5 ANALYSIS 70 dbBML 74 sleeping sa TRACKER 74 dbCDE 76 sleeping sa TRACKER 76 dbPTS 83 sleeping User5 ANALYSIS 83 dbANA 86 DORMANT User11 CPTDB . NULL
Has anyone seen this? Is it related to the installation of service pack 4? (We have installed the services pack on many other SQL servers, but have not come accross this before.
I am trying to find the list of active connections on SQL SERVER , more and more granular way ...like below , I know a way using active monitor or Profiler or some DMVs give me some list , but is there a way to find what is the server name ,instance name connectedc to it , who is the clinet connected to it , whats the application being used now?
what database it is connected to it ? what login being used to connect ? what table and column being used right now and what kind of DML or DDL are happeming ?
I want to create a report and find Dependancay evaluation so that we will re architech or re design the existing databases ...
Is there a way to find active connection to a database so you don't have to wait for a restore or similar operation to fail. (Which take forever).?
Is there a SMO method or a transact SQL command or something that can be used in an application to detect active connections?
I don't want to have to wait forever to get a failure when you can't perform a operation that require that there be no active connection such detach a database. I want to be able to tell when I can perform a operation which requires no active connection and when I need to use a task without out dropping the connection like copying the schema using SMO methods.
However if there are no connection I can perform a detach copy and attach to create a new database which is considerable faster.
I am working now on optimization of an update query for a particular table and I want to measure the number of page splits after each update. How to check it?
I have a Microsoft Cluster running on Server 2003 Entrprise. SQL 2000 8.00.2039 (SP4). 5gb physical memory installed.
With the databases online we run a test failover from the Cluster administrator. It takes about 30-40 seconds and completes without generating any Server Event log errors nor SQL log errors. Everything looks good from an administrative stand point.
However, when we test with running a series of queries to the databases, then failover, we notice that it can take up to 3 or 4 minutes before some of the databases will respond. Connections are not refused, they just sit there.
How can we troubleshoot this or does anyone have a similiar experience with this scenario?
How can we monitor the all tables in all databases and send notifications to the team.Is there a way to check to find the no of rows and size of a table last month and find out growth % now
I've written a DTS transaction that I would like to schedule as a job. I don't want it to run if there is nothing to send.
I this example below on another website and have changed the connection string to reflect my settings. The password has been stared out for security reasons. It's not the way it actually appears in the script. This keeps erroring out on line 21 saying expected end of statement.
I'm sure I'm missing something small and would really like to get this done tomorrow before I leave for the weekend. Any help would be greatly appreciated. Function Main() dim myRecordset dim iRowCount
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. OpDatesessionStartTimesessionCloseTime 2015-01-202015-01-20 14:32:59.1302015-01-20 14:33:14.6299166 2015-01-202015-01-20 06:58:33.7302015-01-20 15:27:16.9133442 2015-01-202015-01-20 09:56:22.8402015-01-20 17:56:29.7555853 2015-01-202015-01-20 05:59:18.6132015-01-20 14:05:19.0426707
[code]....
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 2015-01-20041
[code]....
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 am newbie in SQL Clustering. I have set up a Windows Server Cluster with 2 nodes and am having the following problem with Physical Disk resource for cluster groups:
My Default Cluster Group (named Cluster Group) has IP Address, Network Name, Physical Disk and MSDTC resources. In addition to that my Default SQL Server instance resources are also in this group. I had this initial set up for Active/Passive mode.
Now I am trying to set up a SQL Cluster in Active/Active mode. For this I have to install another instance of SQL Server in the existing cluster and make a separate cluster group for its resources. I made a new cluster group (SQL Instance Group) with an IP Address and a Network Name resource for this new instance but I dont have any Physical Disk resource to allocate to it. As such while installing the SQL Server Instance I get stuck when I'm asked to select the quorum disk to be used.
Is it possible to configure two quorum disks, one for each group? What's the concept of dedicated disks resource for each sql instance in a group? Is this same as the quorum disk? If this is not a shared disk how do I configure a dedicated disk resource for my second cluster group (SQL Instance Group)?
script in SSIS to check data connections/sources and send an email if it fails validation. I found this script online, but I'm not real good with scripting and only VB scripting at that.How can I modify this script or is there another one here that will do what I need. The data connection in question links to Salesforce and will fail validation if the password/security token is invalid.
The reason I need this script is that we have no control over the password changes and need to know if the salesforce team changes the password without informing us.

I would like to know does it exist a relation between number of licenses (per server) entered when installing SQL Server and the maximum of connections obtained by @@MAX_CONNECTIONS ? how can i get the information about the number of licenses after the installation ? Thanks.
I am building a package that involves copying 36 tables from an Access database into like tables in SQL 2000. Many of these tables require transformations and some require lookups. The number of records per table ranges from 4 to 4000. My question is, is it better to have a set of connections(one to Access and one to SQL for each table or one connection for all or some other approach.
hi, Does large number of connections to a sql server result in slogging queries?? by large number of connections I mean in the range of 2000 to 2500 connections to various databases on the same server. This happens on the production database, if I download the copy of the database and run the specific queries on the local box it hardly takes 1 second to execute, whereas on the production box it takes about 45 to 60 secs, i m working on the indexes part... was not sure whether number of connections to a server affect the performance of the queries or it is just that the indexes need defragmentation...
Is there any way to know the number of current connections to an SQL Server Database? Also how can one change the max pool size (for the number of connections allowed to the database)?
How do you find out the current number of connections to a SQL Server 2005 instance in SQL Server Managment Studio? I need to see if my number of connections is exceeding my Maximum Worker Threads.
We are trying to set up an active/active configuration of a SQL Server cluster, and we had a few questions.
Initially, we want to have 2 Database Servers that would share the same Database (both reading/writing to the same tables). However, from reading the MS docs, we find out that we can have what they call an "active/active" configuration using a Cluster but they need to have 2 different disk sets, i.e. having 2 separate databases. If this assumption is correct, how does the data get synchronised between the 2 databases (that are on the 2 different disks sets)?
have you ever heard of an Active/Active SQL Sever 2000 Cluster deployed in a pure OLTP environment?
Some 8 years ago I have learned about a bespoke solution for the SAP ERP system (not the BW!) with DB2 Parallel Server for a huge German company. Then again, I would expect that Oracle RAC might fit into an OLTP environment, although I never heard about a real world implementation.
All this led me to believe clustering is good for failover purposes, and for decision support services, not quite for OLTP applications.
So if you see a point in Active/Active Clustering and OLTP please come forward and explain.
Cheers,
Johann
P.S: For those of you who want to know: Consultants from www.hiltes.com want us to deploy an Active/Active Cluster for their Fashion 3000 Net stock software.
I am using SQL 6.5 and I would like to know (using Isql/w) the number of users connected to my server at any given time. Thanks for your help in advance.
