Maximum Number Of SQL2K Instances
Mar 12, 2001Hi,
I am reading SQL Server 2000 Black book (Coriolis publisher) and Microsoft SQL Server 2000 Optimization guide (Jenney Lynne Fields PH publisher).
In the Black book page 56, it says :"..up to a total of 16 instances.
In the optimization guide page 144, it says :"There is no theoretical limit to the number of instances of SQL server you can run simultaneously..."
Who the hell is right??????

Quick Question Regarding Number Of Instances...
Jan 21, 2005I am developing an application for a client who already has a liscensed SQL server running. They have a software package that requires an instance using "Windows Only" for the authentication mode. I need an instance to use "SQL Server and Windows" for my application to be able to speak with the server from other computers on their network (or at least I believe I do....).
My question is, "is there any restrictions on the 'number' of instances an institution can run on a computer that is liscensed to run the software"?
Alternately, if there is a limit, I need to figure out if it is possible to set up the application (VB6, btw) to connect to the server from outside the host computer if it is using "Windows Only" Authentication. The application will be installed on several computers in the client's network and I'm not familiar with how to dynamicly poll the 'current Windows Login' information.
It would be much simpler for the application to create a new instance with the desired authentication method, but is there a security issue in doing this? Would the data be any more at risk to outside corruption using the SQL server authentication mode?
Returning A Value That Has The Smallest Number Of Instances In A Table
Nov 5, 2007
Hi
Please help! I'm really stuck. I have a table (AssessorAllocations) that stores the data of students who have submitted assessments for marking by an Assessor. Each time an assessment is submitted by a student my program must determine which Assessor has the smallest workload and then assign the current assessment to that Assessor. My problem is how do I determine which Assessor has the smallest number of assessments assigned to him/her.
The table columns are:
AssessorRegistrationNo
LearnerRegistrationNo
QualficationName
SubjectName
AssessmentName
DateAssigned
Marked
DateMarked
Price
So I'm looking for something like this:
Select AssessorRegistrationNo from AssessorAllocations where {Select the Assessor who has the smallest number of AssessmentNames assigned to him/her where Marked='0' and DateAssigned<>''}
Thanks

View 4 Replies View RelatedNamed Instances And Default Instances Of SQL Server 2000
Jul 18, 2001I had a server with SQL Server 7.0
I installed a named instance of SQL Server 2000 and then i passed all my DB
of the 7.0 instance to the 2000 instance.
Then i removed the 7.0 instance, that was the default instance.
So at the moment there is only the 2000 version, but it isn't the default
instance
Can the 2000 instance become the default instance? (So that clients can
connect to it simply through computer name, and not creating an alias)
thanks

Limitations In Term Of Number Of Tasks And Number Of Columns
Jun 5, 2007Hi,
I am currently designing a SSIS package to integrate data into a data warehouse fact table. This fact table has about 70 columns among which 17 are foreign keys for dimension tables.
To insert data in that table, I have to make several transformations and lookups. Given the fact that the lookups I have to make are a little complicated, I have about 70 tasks in my Data Flow.
I know it's a lot, but I can't find a way to make it simpler. It seems I really need all these tasks.
Now, the problem is that every new action I try to make on the package takes a lot of time. At design time, everything is very slow. My processor is eavily loaded each time I change a single setting in one of the tasks, and executing the package in debug mode takes for ages. If I take a look at the size of my package file on disk, it's more than 3MB.
Hence my question : Are there any limitations in terms of number of columns or number of tasks that can be processed within a Data Flow ?
If not, then do you have any idea why it's so slow ?
Thanks in advance for any answer.

Multiple Sql Instances
Dec 1, 2007i have sql server 2005 express running. during install, i had issues with a system dll that i found answers online and resolved. i am still very green, but i know much more now than i did at the time. i believe that as a result of the partial then failed installs i have multiple instances either fully or partially installed. when i am in the sql server mgmt express environment, it lists two sql engines. i only ever use one, and would like to safely remove the second without damaging or corrupting anything done with the other instance.
my reasons for wanting to do this are twofold. first, i would like to free up the drive space taken up by the second instance. (i am a stickler for clean harddrive mgmt and maintenance). second, now that i have used the software and am somewhat more familiar with it, i would consider installing a second, intentional instance so that i may attempt to better customize some of the install-time settings and configurations.
can anybody give me any pointers/ guide me in the direction of information on how to SAFELY go about this?
thank you in advance for any help.

Named Instances
Feb 14, 2002Is it possible to rename a named instance?
We have a vendor product that can only handle up to 18 characters for the server name and the instance name (we did not know this when we created the named instance) and of course our combined name is 19 characters, so it trys to pass the 18 charater name and then fails with the following error:
[LOG] Unable to read local eventlog (reason: The data area passed to a system call is too small)
So, can i rename the instance, or do i have to create a new named instance?
Thanks

Note : sql server subscriptions between different servers in sql server 7 is not the issue.

This is creating a problem with COM because of username and password. I want to reset it to use SQL Server authentication but I can't find where to do it. Can I do this or do I have to delete this instance and create a new one.
