Active Connections
Oct 25, 2000Hello All,
Is there a procedure or function that will return only active, running connections on the server?
Thanks In Advance.
Number Of Active Connections
Sep 20, 2005Hi.
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?
Thanks!
Blocked 'sleeping' Active Connections
Sep 27, 2005Hi
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.

Active Database Connections SQL Express, How Many
Jun 12, 2006How can I determine if everyone has logged off of the SQL Express database, ie, no one else is connected.
I need to clean up some files that are generated in my code, but I only want to do that when everyone has logged off the database?
In MS Access, I could try to re-open the MDB file exclusively.
Is there a connection number etc?
How To Check Number Of Active Connections In SQL Server?
Jan 23, 2002Hi 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 ?

How Can You Find Active Connections To A Database So You Don't Have To Wait To Get A Failure When One Exists.
May 8, 2008Is 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.
SQL Server Admin 2014 :: How To Close Active Connections Or Create Connection Timeouts
Dec 9, 2014we 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.
This settings should be sql server 2008 related.
SQL 2000 Database Response Hangs After Cluster Failover Only When Active Connections Were Present
Sep 26, 2007I 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?
SQL Server 2012 :: Query To Count How Many Sessions Are Active And Remain Active Per Hour
Jan 22, 2015I 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.

Order BY opDate, FORMAT(DATEPART(HOUR, sessionStartTime), '00') ASCResults:

Where I am stuck is how do I count the sessions that remain active per hour until the session is closed with the sessionCloseTime.
There Is Not Enough Disk Space Error While Installing SQL In A Active/Active/Passive Cluster
Mar 5, 2008
Hi
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.
Any help will be much appreciated.
Regards
Adnan
Active/Active SQL Server Clustering With Multiple Instances
May 12, 2008Hi
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)?
Anyone could please help me out with this?
Are There Any Issues With An Active/Active Cluster With A Remote Mirror For DRP
Nov 30, 2006Hi folks,
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.

Active/active Sql Server Config; Shared Dbs
Nov 2, 1999Hi,
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)?
Can anyone help? thanks

ACTIVE/ACTIVE SQL Server 2000 Cluster
Oct 12, 2002ACTIVE/ACTIVE SQL Server 2000 Cluster
This was my plan.
Physical box - box1,box2
virtual box - virtual1
i have a active/passive cluster virtual1 (primary node box1, secondary box2)
I am creating another virtual box on box2 as primary node by name virtual2)
whenever my installation setup runs my default server name is greyed out. it always requires a instance name.
Is that the way it should work?
i can only use instance for active/active failover?
please advice

Active/Active SQL Server Cluster And OLTP
Sep 27, 2005Hello folks,
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.
SQL 2000 Active/active Cluster And Different IP Adresses
Mar 22, 2007We 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?
Applying SP To 2005 Active/active Cluster
Jun 8, 2007I 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?
Thanks
Active / Active Cluster Win2K
Mar 5, 2001Hi
While configuring an active / active cluster, do I need to run the SQL setup on both nodes?
The SQL2K setup installs binaries on localdisks of both nodes - hence the question.

Active/Active Clustering Config
Feb 22, 2000I have setup an active/active clustering environment for SQL Server, however it is 2 seperate virtual servers. How can I set them up to exist as one virtual server containing both active installations? Can this be done? I have two compaq 8500 w/8 processors each. I need to be able to cluster these configurations to take advantage of all 16 processors in one virtual SQL Server. Can it be done?
If you can answer these questions, you will have my undying gratitude.
Thanks in advance.
SQL7 In Active/active Cluster
Sep 21, 2000Hi
I am running some tests on SQL7 in an active/active cluster and have a couple of queries
1. When I create an ODBC DSN, why is the "Use the Failover SQL Server if the primary SQL Server" checkbox disabled
2. To test, I was running SQL queries from Access over the DSN created. When the Primary Server went down, I had to reconnect to re run the query - Is this normal?
3. Can someone point me to any documentation on the above scenario that would shed some more light?
Thanks

Upgrad SQL 6.5 To 7.0 In An Active/active Cluster
Oct 26, 1999I currently have a two node HP hardware active/active cluster server. Running windows NT 4.0 Enterprise and dSQL server 6.5 sp 3. I want to upgrade the cluster to SQL 7. I would like to know if anyone ran into any problems or has sucessfully attempted this.
Also I read a few months ago about a gottcha involving NT sp4 and SQL sp5a that would prevent a node from failing over. Has this been corrected and does it affect SQL 7.
thanks
Active/active SQL 2000 Cluster
Sep 27, 2002Hi
Is there anyone who knows where I can get some information about
installing an ACTIVE/ACTIVE SQL 2000 Cluster server (MSCS).
I have no problem setting up an active/passive failover cluster.
Where can I get more information? Do I need two instances? Two databases?
What's the difference between active/active and active/passive?
Thanks!
Active/active Sql Server Cluster
Jan 20, 2004Hello, Can anyone please explain how the failover processes works on a sql server 2000 2 node active/active cluster.
Given the following
You have 2 node active/active cluster NodeA & NodeB
Question
1. How many SQL instances need to be installed on each node?
2. If the answer to question #1 is one instance per node, then
say if NodeA fails NodeB will take over all the resources of NodeA
including the master database, How does that work , how can once instance (in nodeB) handle two master database i.e its own master database and the one taken over from NodeA.
RAM Config For Active/active Sql Cluster
May 18, 2008Hi,
I've just setup an 2 node active/active sql cluster (my first). Both servers have exactly the same specification, 16GB of RAM each and SAN attached. My question is, how do I configure the min and max memory for each sql instance. I've read some where that I need to follow the 20-40-40 rule as, 20% for the OS, 40% for the active sql instance on the node and the other 40% is for the other sql instance if it fails over. Are there any other gotcha that I need to be aware of? Can someone share some light with me in regards to this? Thanks

Detect Active/Active Node
Jul 3, 2007We have an active/active node setup with SQL 2005. Does anyone have any samples of VBS I could use to see what node is actually taking requests at a certain time? What I want to determine is what the actual active node is.
Thanks.
2 Node Active Active SQL Cluster
May 18, 2006I want to host 2 seperate SQL databases and wanted to know if it would be possible to run this in an active active cluster config which each database running on a different server.
The clustering would be there in the event of failure of one of the servers but for normal operation the two sql instances would be completely seperate.
Is this configuration possible and would this give the best performance and resiliance from a 2 server setup.
What do you think?
Active/Active CLuster Can Not Add 2nd Node
Jun 3, 2007Help, I have an active/active cluster with SQL2k5 Ent with SP2 installed on node1 that is currently running live apps, I need to add the 2nd node to have fail over functionality but if I use the Change Install from Add or Remove Programs on the primary node to add the 2nd node I get the following error.
"The File 'c:....SqlRun_SQL.ms' is not a valid installation package for the product Microsoft SQL Server 2005(SQL2K5VVS01). Try to find the installation package 'SqlRun_SQL.msi' in a folder from which you can install Microsoft SQL Server 2005(SQL2K5VVS01).
No I assume this is because node 1 has had service pack two applied. Does anyone have instructions how I can add node two without having to completely uninstall Node 1, as the doc€™s with SQL2005 SP2 say it can not be removed, a complete uninstall of 2005 must be done???
