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 have written an application in VB6 connecting to a SQL Server 2000 database using ADO. This app is running on the same computer as SQL Server.
What I am seeing now is that each day 2-3 new connections are being created by SQL and these connections have a "sleeping" status and "AWAITING COMMAND" command. Also, when double-clicking a connection, it's last TSQL statement is empty... This way, connections are piling up.
Does anyone have an idea why this is happening and what I can do to avoid this ? Also, how can I determine what is causing this ?
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?
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 ?
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.
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.
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?
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 having some teething problems while installing SQL on a 3 node cluster. Within the Cluster configuration I have 3 Cluster Groups with each of them having their associated disk resources. All these disk resources physically exist on a SAN.
The actual cluster is running absolutely fine and I can access all the disks from their respective owner node. The problem only starts when I start installing SQL Server 2005 on this cluster. I specify the Cluster group from the Cluster Group Selection and choose the desired partition and then the error message pops up
"There is not enough diskspace on the destination disk for the current SQL Server data files. To proceed, free up disk space to make room for data files, or install the data files to a different drive"
But the disk I am trying to install it on is 264Gb and none of it is used. I have also tried to change it to a different disk within the same Cluster group but to no avail. I have even tried to install it in a different cluster group all together but I get the same error message.
I have googled around havent found anything so far. The disks have got full permissions for the account I am installing SQL with.
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)?
We are going thru the process of scoping an active/active cluster at one site. I was wondering whether there will be any issues with mirroring (DB by DB) off the cluster into non clustered server at an alternate DRP site.
If an MS SQL 2005 Connection is sleeping in the activity monitor, does it mean it's not closed? I'm pretty sure it's closed, just want to confirm. Lately, our DB server got hammered with requests and it reached max-pool size (we implemented caching after that).
what does the sleeping process will do I am running the following stored procedure the cpu value is increasing by time. I am killing old process manually. How to stop the sleeping processing.
CREATE PROCEDURE SP_MONITOR2 AS select spid, hostname,cpu,status,datediff(mi,last_batch,getdate ())Diff_in_Min from sysprocesses where hostname <>'' and last_batch <>'1900-01-01 00:00:00.000' order by Diff_in_Min desc
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.
We run several SQL 2000 SP4 instances on IA64 active/active cluster. The OS we run with is Windows Server 2003 SP1. We have different network cards : 2 network cards teamed for production purposes in domain X and 1 network card dedicated for problem solving in domain Y. First we configured the cluster with only the 2 teamed network cards for production purposes in domain X. Later we introduced the second network card for problem solving in domain Y. Everything looks fine. The (virtual) SQL instance listens on two different IP adresses on TCP port 1034. If we try to make connection via isql, EM or Query analyzer than we can directly contact the SQL instance from a workstation/server within domain X but this doesn't work form a workstation/server within domain Y. However if we use the specific TCP port in the connection in domain Y the connection is setup. We wish however not to use explicit TCP ports in setting up connections. Has anyone experienced the same problem before or has anyone an idea how to solve the problem?
I have a 2005 active/active cluster and want to apply SQL server 2005 SP2 to both node. I know that for active/passive , the sp can simple be installed on the active node(instance) and everything will be replicated to the other node. bear in mind what I have SSIS and SSAS and SSRS running on the active/active cluster.
what is the rigth method for applying the SP to activeactive cluster?
I have SQL Server 7.0 and I am not able to kill one of the SPID's who is running a SELECT Statement and showing as sleeping. When I saw in the current activity in EM I see the STATUS as sleeping COMMAND as SELECT, APPLICATION as Microsoft Transaction server, WAITTIME as 7877 and WAITTYPE as EXCHANGE and CPU 10074 Thanks in advance.
I have processes running on the server that show a status of "sleeping" from sp_who and sysprocesses, however they are still running. I run sp_who over and over again and only occasionally the process status shows running, and then switches back to "sleeping" or "defwakeup". I know what all the statuses mean, I just don't know why a running process would ever show as "sleeping". The processes take a very very long time to run as well.
I may be asking a foolish question but I really need an answer for it.. We have our centralized servere where SQL Server 2005 is installed.... Whenever open the management studio from our desktops, execute some queries (It may be any simple query such as select * from) I find the status of that process 'sleeping'...untill we close the studio or in other words untill that process is killed..
I find the status by Management -> Activity monitor...
Please help me with it...
Has there been anything wrong while setting up Sql Server ?
I was trying to find the bottle neck on our server while we wererunning a couple very large updates.I ran the following query and noticed there were a couple sleepingspid's that were really eating up the memory. One had a value of16000.I guess my question is was this query still holding on to that memoryeven though the query had finished? Why didn't SQL Server clean it up?select spid,substring(Loginame,1,10) Login,memusage,substring(hostname,1,15) Host,program_name,cmd,statusfrom master..sysprocessesorder by memusage desc

We have a web application with multiple users connecting to SQL Server 2005 database.
Once the users start using the system, I could see in the Process Info from the activity monitor with a several process with status as sleeping and command as Awaiting Command.
I have few questions regarding this for which simple answers would help me ( I searched and couldnt understand from the pages that explained the process information )
My questions are,
1. Does the processes with status sleeping and command as Awaiting Command are needed for the application even after the operations specific to them are complete?
2. Does these process affect the performance ?
3. Does killing these process would affect the application connectivity ?
4. Why do we get several process with status sleeping and command as Awaiting Command? Is this because of the front end programming errors ?
5. What should we do to avoid the increasing number of process with status sleeping and command as Awaiting Command?
Dear, Our ASP.NET scripts send SQL statements (as inline SQL or SP) to process the requested job. After the job execution, the process ID stays in the server and waits for next command with sleeping status.Since this process does not go away, next job adds another process and eventually, the server is overloaded with these processes and dies. How can I kill this sleeping processes?Regards,Echo
