In an instance with 2008R2, the value of Transactions/sec in Master DB is very bigger than an instance with 2012.
Is it normal? I ask it because both instances execute the same application with the normals differences between them (the Transactions/sec's number for the application's bds is similar).
how many transactions per second transactional replication can handle?
Server has 128GB RAM, 12 core 2 Process (24 core total) each transaction is approximately 32k.
Publisher and Subscriber are on different servers on same LAN, separate disks for logs, data, indexes and tempDB.
I've found data on how many transactions per second SQL Server can handle but nothing on replication.
I have a update trigger. In this trigger I need to insert few records in 3 tables. If error comes in any of these inserts then previous inserts to get committed. This trigger was written in Sybase and it was possible to create transaction and commit the transactions.
View 4 Replies View RelatedSo I've been monitoring long-running transactions on a SQL Server that hosts a couple of vendor-supplied databases that look after our factory.Today I noticed a pair that have confused my Excel spreadsheet (that I've been using to analyze these transactions).So here's the weird thing that I spotted. Given this query:
SELECT p.spid, p.login_time, at.transaction_begin_time, datediff(second, p.login_time, at.transaction_begin_time) as [difference]
FROM sys.sysprocesses AS p INNER JOIN
sys.dm_tran_session_transactions AS st ON st.session_id = p.spid INNER JOIN
sys.dm_tran_active_transactions AS at ON st.transaction_id = at.transaction_id
[code]....
I had a look in the event log on the server, which had just been rebooted at around that time. It seems that the clock got changed on boot-up, with the size of it quite surprising. This meant that these processes were able to start their transactions *before* they logged on. Hopefully this doesn't cause any other weird problems.So I've requested an investigation about time synchronization on our virtualization hosts... and in the mean time, have set the SQL Server services to 'delayed start'.
I vaguely remember reading somewhere that all distributed transactions are executed at Serializable Isolation Level "under the covers."
1. Is this true?
2. What does "under the covers" mean in this case; i.e. will I not see the isolation level represented accurately in requests?
It is my understanding that when having LinkedServers, the option "enable promotion of Distributed Transactions for RPC" should be set to TRUE, so we can rollback , if needed, remote transactions. At least, that's my understanding of that setting.
Having said that, the TRUE setting is affecting this particular TSQL code, inside an sproc, which I would prefer not to alter:
Insert into #TempTable
EXEC ServerB.MyDatabase.MyStoreProcedure
@param1= '',
@param2= ''
When set is set to TRUE (current setting) I get this error:
OLE DB provider "SQLNCLI11" for linked server "ServerB" returned message "The partner transaction manager has disabled its support for remote/network transactions.".
Msg 7391, Level 16, State 2, Line 28
The operation could not be performed because OLE DB provider "SQLNCLI11" for linked server "ServerB" was unable to begin a distributed transaction.
... when set to off, the error goes away.

View 1 Replies View RelatedI was reading that when applying 2008 R2 SP1 you need to run the MDS update component manually: [URL] I was curious if that package changed in later service packs because I couldn't find any mention of it.

I have been using SSIS for a while now, originally in SQL 2008 but more lately SQL 2012.
I discovered the GETDATE() function in SSIS so I thought I would use this in a variable expression in a Master/Driver package with the child parameters mapped to this variable. A big mistake. The value is not persisted, it gets updated each time the variable is read, so it's back to setting the variable value using a script task in the Master/Driver package.
I am working on a Login migration issue. I have the Master database from the original database, that I have attached as a User Database, call it OriginalMaster. I also renamed the mdf and ldf files, before attaching, just in case.
I want to select the logins from the OriginalMaster, and using sp_help_revlogin script all the Logins out. I know there were many logins in that database. But what I am seeing, are all the Logins from the Current Master database. Which are only 7 Logins.
How can I select the logins, or script out the Logins from the OriginalMaster database?

Master table which has [ID],[Timestamp]

CREATE TABLE DHS(CUSTOMERNBR VARCHAR(20), CONTRACT VARCHAR(20), SUBCONTRACT VARCHAR(20) , STARTDATE DATETIME, ENDDATE DATETIME, EFLAG VARCHAR(20), HFLAG VARCHAR(20))
The data which will be going into this table is from two table which have a 1 to many relationship:
Here is the 1 side and data:
CREATE TABLE CUSTOMERS(
CUSTOMERNBR VARCHAR(20),
CONTRACT VARCHAR(20),
SUBCONTRACT VARCHAR(20),
STARTDATE DATETIME,
ENDDATE DATETIME DEFAULT '12/31/2099')
[Code] ....
Here is the Many side and data:
CREATE TABLE FLAGS(CUSTOMERNBR VARCHAR(20), FLAGCODE VARCHAR(20), STARTDATE DATETIME, ENDDATE DATETIME DEFAULT '12/31/2099')
INSERT INTO FLAGS(CUSTOMERNBR, FLAGCODE, STARTDATE, ENDDATE) VALUES('10001000101', 'H', '02/01/2014', '03/31/2014')
[Code] ....
The CUSTOMERS table holds the record date span into which the FLAGS table records have to "fit". In no case will the date spans from the FLAGS table fall outside the STARTDATE - ENDDATE span in the CUSTOMERS table for any CUSTOMERNBR. Here is an example of the final expected output in the DHS table from combining records in the CUSTOMERS and FLAGS tables:

I used "MDSModelDeploy deployclone" do deploy a package with EntityA, EntityB and EntityC to a production environment. I then deleted EntityB from my dev environment and used "MDSModelDeploy deployupdate" do update the model in prodution. After the deployUpdate, EntityB still exists in production. Is there something special I need to do (option of MDSModelDeploy?) in order for the deploy to delete an entity during a migration?

We have an application that runs Jobs, each of which affect ## number of child objects (usually around 1M). When a thread gets to 5000 updated child objects it bulk inserts into a table called ActionLog with the child Id and JobId.
When the job is complete a sproc SUMs the children from the ActionLog table:
select sum(id) from ACTIONLOG where JOBID = @JobId;
It then updates the Jobs table AffectedObjectCount column with the sum(*) from above.
Instead of writing to the ActionLog table and calculating the SUM at the end I would like to do this 'real time'. After the bulk insert I would like to update the AffectedObjectCount column with the number of rows that were just bulk inserted. I tried this in the past and ran into major contention issues. There are usually 20 threads running a job so there exists a lot of potential for deadlocks.
Is there a recommended way to handle updating one column on one row from multiple threads? What is the best practice for a counter like this?
Hi there,
I have decided to move all my transaction handling from asp.net to stored procedures in a SQL Server 2000 database. I know the database is capable of rolling back the transactions just like myTransaction.Rollback() in asp.net. But what about exceptions? In asp.net, I am used to doing the following:
<code>Try 'execute commands myTransaction.Commit()Catch ex As Exception Response.Write(ex.Message) myTransaction.Rollback()End Try</code>Will the database inform me of any exceptions (and their messages)? Do I need to put anything explicit in my stored procedure other than rollback transaction?
Any help is greatly appreciated
I have a piece of code that has happily run daily for at least 4 years. I have moved it to a machine that is meant to have an identical set-up, and it fails. I need to work out why it fails, but I am stuck. The code works as follows:
CREATE storedProc1 (Parameter1, etc)
DECLARE @TransactionName nvarchar(127), @TransactionActive bit
-- Plus Other Variables...
BEGIN
BEGIN TRY
SET @TransactionName= 'TransactionName1'
SET @TransactionActive = 'True'
BEGIN TRANSACTION @TransactionName WITH MARK
[Code] .....
When I EXECute StoredProc1, it fails with the Error Message "Cannot roll back . No transaction or savepoint of that name was found." I think that message comes from a ROLLBACK TRANSACTION statement in the CATCH of StoredProc2. I have tried commenting out that ROLLBACK statement, which changes the error message to: "Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 1, current count = 2."
Background: In my current company the business users maintain a huge quantity of master data using excel. Then a series of SSIS jobs are edited and manually executed.
Goal: the challenge is to replace this process using MDS. One of the requested features is the possibility for the users to edit or insert new master data using the Web UI or the Excel Add-in and when they are done perform a merge of the master data in the target, in this case in the reporting DB.
The perfect solution for me is something like trigger the execution of a SSIS package to export the data from the subscription views to the reporting DB after the business rules are apply to a specific entity.
Sometime during the night last night some user account permissions were "lost". Am I right to think that restoring the master database would be the way to go? We have a 2 node 2012 cluster and I stop the cluster resource and start the db in single user mode from the active node. Somehow the sharepoint farm is still trying to connect so I can't get logged in single user. What method could I use to stop users from connecting when I don't have access to the sharepoint farm.
View 8 Replies View RelatedI got a File with sales orders and their details.
Step 1. First I am filtering the Sales Order information and inserting it in my Sales Orders table.
Step 2.Then I am filtering the details from the sales Order and inserting them in the respective table.
My Problem is that the Sales Order File does not contain the Sales Order key (ID), this is generated by the SQL Server. How can get it in order to use it in the second step? I need it because it is a foreign key in the details table.
Any Idea?
Hello,
I'm new to SQL and need help with a query. Not sure if this is the right place.
I have 2 tables, one MASTER and one DETAIL.
The MASTER table has a masterID, name and the DETAIL table has a detailID, masterID, and value columns.
I want to return a populated MASTER table with entries based on the DETAIL.value.
SELECT MASTER.*
FROM MASTER
WHERE DETAIL.value > 3
This is a simplified version of my problem. I can't figure out how to set the relationship between MASTER.masterID and DETAIL.masterID. If I do an INNER JOIN, the number of results are based on the number of DETAIL entries. I only want one entry per MASTER entry.
Hope this makes sense.
How can I do this?

Hi All,
How can we change connection properties in a DTS pkg with connection?
You can loop through the connection count but the connection ID is not static one.So can’t rely on that.
Is there another way of changing connection properties?
Thanks in Advance

Hi all....
I am currently designing a DTS Package to import data that is processed daily into a large database.
I have to design the package such that if any step fails when importing, I roll back the entire transaction.
I have designed the package with this in mind, checked "join transaction if present" and "rollback transaction on failure" in all of the workflows. I have also made all workflows serialized.
However, when I run the package, it fails on one of the data pumps with the error:
Transaction context in use by another session.
Any ideas?
Thank you,
Brian
