Need Information On SQL SERVER 2000 With Multi-threading CPU
Nov 23, 2005
Hi,
I have SQL SERVER 2000 SP4 Enterprise , Windows 2003
Enterprise on
Xeon 4 Processors (now with multi-threading CPU) and I have
questions which
seem weirds to me (used to have the same config without
Multi-Threading) as following:
1. SQL Server see 8 CPUs. Is this because of
multi-threading CPUs ?
2. when use SP_WHO2 ACTIVE ,
2.1 Result has user SPID , which block
itself
(it is UPDATE and SELECT
statements, most often)
2.2 Result has user SPID , show more
than one result rows with
the same processe and command
3. when use Properties of SQL Server , it has an
error 15407 in log.
many thanks in advance

We're moving in a 4-socket (Xeon Dual Core CPU's) server. What version and product of SQL Server should I be looking for to fully take advantage of the new server's 4 processors. I'm not sure I understand the licensing per CPU. Is there any advantage in waiting for SQL Server 2008 as it concerns multi-threading and what should I be looking to spend for a SQL server solution that utilizes all four processors. Someone has told me that the SQL Server standard edition comes with 4 cpu licenses. Is this correct?
Thanks, Rob Huylo

I have a vb 2005 app that executes a SSIS package in threads.
The SSIS package imports a large (20mb) file, does many alternation to it, exports it to the database.
The SSIS execution is quite frequent and there for multi-threading is needed.
Here is the issue:
If i take out the threading everything works great. The second that i add threading, and try to execute a few instances of the SSIS it starts crashing. The thing is that it errors out in different task and is completely unpredictable.
My question:
1) Can SSIS be used in a multi-threading environment?
2) If yes, How do i do it?
3) Does anyone have any suggestion as to what i should try?
p.s. Timing is definitely an issue for me. I got to get this working, tested, approved by 8/27/2006
---------
here are the 3 errors that i'm getting when i turn multi-threading on
1)Thread "WorkThread0" has exited with error code 0xC0202009.
2)An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Transaction (Process ID 112) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.".
3)The ProcessInput method on component "(i cannot display the name of the task for security reasons" (448) failed with error code 0xC0202009. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.

Apologies if this is not the right forum.
We have some c~ code which calls a stored proc to trnsfer data from one db to another.
We are using multi threading to allow a whole days data to be processed in parrallel.
However, we are experiencing problems. After a while we get the following message:
"An exception during changed data captured caused all processing threads to abort".
Can anyone tell me what posssible reasons would cause this to happen?
It is not an area in which I have a lot of expertise, the code was written by a third party.
Many thanks

I have an SSIS package that is running the same set of stored procedures on about 50 remote database servers and importing the data through data flow tasks into a local database.
To do this I have a db table set up with the remote server and db names and using variables, i am looping through each one and getting the data. Everything works wonderfully...however, I need to find a way to be able to run multiple calls at the same time. Is it possible to multithread SSIS so that I can run 1 server retrieval on 1 thread and another retrieval on another thread? Any other suggestions on how to optimally do this?

I have a question:
Is SQL Compact Edition safe to use in ASP.NET WebApps?
And second if so, should i use transation isolation level or row locking hints to assure data quality during iniserts?
E.g. i want to assure that there is only one record named user2@domain2 and thus i want to make sure that my code
will not fail in a mutli-theaded scenario and insert second one or get a key exception back: see sample
transaction or locking hit{
select from users ....
if no user found
insert into users
}
Thanks

Hi,
I've went throught the SP4 documentation but I didn't find a clear answer about how to deal with this situation:
In the situation of a multi instances server in which all instances are SP3a, can I just upgrade a couple of instances to SP4 and leave the others in SP3a ? .
One of the instances I may have to leave in SP3a belongs to a merge replication environnement (Distributor and Publisher), while the Subscriber is also in SP3 on a remote server (which I don't administer..).(the point is that in this situation I have to upgrade the 2 servers simultaneously)
In other words, when I 'll apply the SP4 to just one instance, I understood that the all the tools will be upgraded to SP4.
Will the merge replication involving a SP3 instance on the same server still work?
Thanks for your comments/replies/ideas.
Regards,
jalal

I have some threading questions, please explain how these work. Thanks!!
How do the threads get created (programmatically, network, or through sequel)?
If I have 10 people in an application, is a thread created for each user?
If I run a large process can I subdivide the process and run it through mulitple threads?

I am new to Reporting Services and hope that what I am looking to do is within capabilities :-)
I have many identical schema databases residing on a number of data servers. These support individual clients accessing them via a web interface. What I need to be able to do is run reports across all of the databases. So the layout is:
Dataserver A
Database A1
Database A2
Database A3
Dataserver B
Database B1
Database B2
Dataserver C
Database C1
Database C2
Database C3
I would like to run a report that pulls table data from A1, A2, A3, B1, B2, C1, C2, C3
Now the actual number of servers is 7 and the number of databases is close to 1000. All servers are running SQL2005.
Is this something that Reporting Services is able to handle or do I need to look at some other solution?
Thanks,
Michael

Ello,
We have quite a few SQL Servers running on servers with hyper threaded enabled processors. We have always left hyper threading on, even on our very busy servers but i've recently begun to question this due to comments i have received.
All our servers run SQL 2000 SP3a as "support" for hyper threading was added in SP3a
So... What do you think of Hyper Threading any why?

Over some time now, I've been developing a fairly hefty stored procedure, that does a lot of computations, and fairly few table lookups.
When I look at the performance on my server (a dual Xeon HT) I can see that it only uses 1 out of 4 possible "cpus" to work on the calculations, while the three others idle out, and was wondering if I can somehow force it to use max available CPU power?

All,
We are experiencing some problems when running the same package on multiple threads of a C# application concurrently. The package instances seem to share a Dts.Variables collection.
I have created a test application and package to reproduce the issue. The package is very simple. It has two variables - Instance (Int32) and Content (string). The test application runs two concurrent threads that run through 25 iterations running the package. Each thread loads the package, sets the instance, and then runs the package. The package then takes the instance, sticks it in the Content variable and then writes it to a file called "FileX" where X is the Instance. Thread 1 sets the instance from 1 to 25, thread 2 sets it from 26 to 50. The test execution results in about 15% of the files containing the incorrect "instance content". That is, I'll see "42" in the file named "File14", or something along those lines. This tells me that the variables are being overwritten.
I ran another test where I created a copy of the package, so the code is identical, but the VersionGUID is different. Running the thread test application always succeeds. There is no file name/content mismatch. I then ran another test where I manually edit the XML of the package to change the VersionGUID before the package is loaded (by calling LoadFromXml). Again this never fails.
Changing the VersionGUID may work for us, but it is a total hack. Has anyone else experienced this or have any other solutions? Any thoughts on manually updating the VersionGUID to get around this problem? I hate doing this, but we are getting desperate.
Thanks in advance,
Rob

Hi,
I need to import an SQL string from MS Excel 2003 to SQL SERVER 2000.
The string I need to import is composed by 5 different several blocks and looks like:

CommandLine02 = "SELECT Block ..."
CommandLine03 = "GO
ALTER TABLE Block...

CommandLine04 = "UPDATE Block..."
CommandLine05 = "SELECT Block..."

If I have several stored procedures, all of them making inserts/updates to the same tables, what is the safest way to run them in sequence?
The context is an asp.net application; I have an aspx page where a click on a button (or more) will launch stored procedures in execution. I have encountered the unfortunate situation before, when stored proc #2 started long before stored proc #1 finished and this caused problems.
If I group all stroed procs in one that simply calls all of them in the needed sequence:
exec stproc1
exec stproc2
.....
exec stprocn
Will they execute in a single thread? Is there any guarantee that stproc2 will be executed when stproc1 finishes, and so on?

Hi,
I'm working with SQL 2000 and am just learning about Maintenance Plans (MP). They seem convenient, but after some time, I'm wondering if they're the best approach long-term. Here are my experiences.
Using the MP Wizard, I created a plan with tasks from all the dialogs:
- Optimize database
- Check integrity
- Backup database
- Backup transaction log
- Write a report
I was puzzled to find 4 jobs were created, each with just 1 step, and staggered starting times. I expected to find 1 job with 4 steps. So, brimming with confidence, I did just that. I combined all 4 into 1 job, deleted the 3 other MP created jobs, and checked for any job-specific details in the code. However now when I open the MP, I get this pop-up:
"One or more of the jobs created for this plan has had additional steps added to it. It is not recommended that jobs created by the maintenance plan be modified in any way."
Okay, fair warning. Yet it appears the job and all steps run successfully, both on demand, and on a schedule. So now I'm wondering if jobs always need a MP. If I don't mind working with xp_sqlmaint syntax, it appears the only thing I'm giving up is the MP history. But I expect job history and '-WriteHistory' will minimize that loss.
I searched BOL, this Forum, and Google, and found a couple articles. One author preferred the ease of the Wizard, another preferred the control and added features of T-SQL, but both created a MP in their examples. So I'm hoping some experienced DBAs can advise.
If I create a job with multiple steps, and no MP, are there important things I give up or problems I create?
Is this approach a bad idea in SQL 2005?
At this stage, I don't need replication or other advanced features. Just simple database maintenance.
Thank you,
- Martin

I've seen a few posts in the MSDN documentation (see links below) stating that the MergeSynchronizationAgent no longer requires the STA threading model in SQL Server 2005 SP1. However, I'm still receiving the following exception message in my synchronization code (where it attempts to access the SynchronizationAgent property):
The MergeSynchronizationAgent class must be instantiated on a Single-Threaded Apartment (STA) thread.
I have Service Pack 1 for SQL Server 2005 installed on both my server as well as my local client (the client is running SQL Server 2005 Express). How can I verify the correct files are there (e.g. are the some specific date/time values for the RMO/COM objects?

Disaster Recovery Options based on the following criteria.
--Currently running SQL 2012 standard edition
--We have 18000 databases (same schema across databases)- majority of databases are less than 2gb-- across 64 instances approximately
--Recovery needs to happen within 1 hour (Not sure that this is realistic
-- We are building a new data center and building dr from the ground up.
What I have looked into is:
1. Transactional Replication: Too Much Data Not viable
2. AlwaysOn Availability Groups (Need enterprise) Again too many databases and would have to upgrade all instances
3. Log Shipping is a viable option and the only one I can come up with that would work right now. Might be a management nightmare but with this many databases probably all options with be a nightmare.

More often than not, I typically don't touch DTC on clusters anymore; however on a project where the vendor states that it's required. So a couple things here.
1) Do you really need DTC per instance or one for all?
2) Should DTC be in its own resource group or within the instance's group?
2a) If in it's own resource group, how do you tie an instance to an outside resource group? tmMappingSet right?

Can anyone help me with this problem?
