Limited Number Of Connections To SQLMobile?
May 5, 2006
Using System.Data.SqlClient is there a limit to the number of connections an application can have to a SQLMobile dB?
If
you have a look at the url below, it says "A device can only have a
small number of connections to an instance of SQL Server at any time"
Does this mean 2, or 8 or what?
Should a app try to use only 1 connection throughout, or can we get away with 2-3?
Is this the same on WM5.0/PPP2003?
Any advice in this area much appreciated!

p.s. I'm not interested in connection pooling!

I created a login in SQL Server 2005 for SQL Server Reporting Service training purpose. It seemed the login exceed the connection limit. There were 9 people in the training and some people got the connection errors. Sometimes the connection error went away after the user re-established the connection. Is there a default limit per login? If so, what is the default? Can I change it to unlimited? And how?
Thanks.

I€™m working on a database project that will ultimately contain millions of records for each lot. In addition, each lot will have up to 96 corresponding serial number records.
I would like to add a SQL parameter that would tell the database engine to only return X number of records.
For Example:
If table TBL_LOTS contains one million records I would like to limit the return set to 100 for example.
What would I need to add to the SQL command to below to restrict the data set to the first 100 records in the set of one million?
SELECT [LOT NUMBER]
FROM TBL_LOTS
WHERE [STATMENTS]

Hi,
When starting a SQL Server Project in Visual Studio, there are a very limited number of assemblies available to reference. Does anyone know why?
Specifically I would like to use "Microsoft.AnalysisServices.AdomdClient". Does anyone know how I could do that?

I have been tasked with processing a large tabular cube using SQL AS 2014 (with latest CUs).The three Fact tables having 1.2 billion rows (in each table)  have been divided into 30 vertical partitions to aid in parallel processing. So around 40 million rows per partition.
Using SQL Profiler to monitor the Row counts (IntegerData) of records processed seems to max out around 2 million rows per minute, then tapers down to about 200k /minute.
The processing is taking over 14 hours and I need to get it lower if possible. The server has 48 cores (2.66MHz) and over 1TB RAM installed. But I really don't ever see CPU exceed 20% having a maximum of 206 threads running on the instance msmdvr.exe
Available RAM is always at least 30% (or 300GB).
I have increased the Vertipaq MIN/MAX 60%/80%
I have increased the OLAP / Processing / Max Thread Pool Min 500 and Max to 1000.
The connection properties have been increased to allow 100 connections, the majority of the processing consumes about 92 connections for the 90 large partition views for the facts.
What can be done to increased the server resource utilization and decrease processing times?
I have increased both

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.
Thanks for your input.

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...

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?
Thanks!

I am new to SQL Server 7 and am not sure how to handle setting up/importing FoxPro databases. The consultants that setup the database before me have combined all of the FoxPro databases into one big database in SQL server. The reasoning was that for user applications to have access to different databases in SQL they would need a connection for each database they are using, so if all the data is put into one database then the user would only have one database connection instead of 6 or 7.
Does this make sense to anyone? Someone else thought that this might have been true is SQL Server 6.5 but not in SQL Server 7.0.
Any help will be appreciated.

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,
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.

Hi,
Environment:
I have a Sqlserver 6.5 production server used for web based applications
Compaq 5500 4 GIG RAM, 4 processor
Sql Memory config on that server is 1048576 (which is 2048 MB)
and the run value is 640000 (which is 1250 MB).
runvalue for user connections was 500
We have only 90 user connections may increase upto 100 depends on the connections. We don't have any overload on that server.
Error: I was seeing
"unable to connect maximum no. of 500 configured user connections are already connected" in the error log.
Action Taken:
I increased the user connections to 600
and rebooted the server. Immediately the same error I can see in the error log. But we have only 20 user connections at that time. I can able to connect.
Please advise me to get rid of this error.
Thanks,
Anu.
