Application Locks Up When Trying To Write To Db After A Replication Where I Create The Database.

Jan 3, 2008

Hello all,

When I create a new database and replicate to it using BeginMonitoredBackgroundSync :







Code Block

public void BeginMonitoredBackgroundSync(string User)
{
CreateReplicationInstance(User);
repl.BeginSynchronize(
OnSimplifiedSynchronizeComplete,
SqlCeReplication_OnStartTableUpload,
SqlCeReplication_OnStartTableDownload,
SqlCeReplication_OnSynchronization,
repl);
}




private void CreateReplicationInstance(string User)
{
repl = new SqlCeReplication();
string host = repl.HostName;
repl.HostName = User;
string dbFilePath = "";


dbFilePath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) +
"\" + repl.HostName + ".sdf";
string myConnectionString = string.Format("Data Source = {0};PWD = {1}", dbFilePath, sqlSettings.Items["SqlPassword"]);

repl.InternetUrl = dynamicsReplicationSettings.ReplicationSettingsItems["InternetUrl"];
repl.PublisherSecurityMode = SecurityType.DBAuthentication;
repl.Publisher = dynamicsReplicationSettings.ReplicationSettingsItems["Publisher"];
repl.PublisherDatabase = dynamicsReplicationSettings.ReplicationSettingsItems["PublisherDatabase"];
repl.PublisherLogin = dynamicsReplicationSettings.ReplicationSettingsItems["PublisherLogin"];
repl.PublisherPassword = dynamicsReplicationSettings.ReplicationSettingsItems["PublisherPassword"];
repl.Publication = dynamicsReplicationSettings.ReplicationSettingsItems["Publication"];

repl.Subscriber = "RemoteSubscription" + repl.HostName;
repl.SubscriberConnectionString = myConnectionString;

repl.ConnectionRetryTimeout = 120;
repl.LoginTimeout = 120;
repl.CompressionLevel = 6;

if (File.Exists(dbFilePath))
{
FileInfo info = new FileInfo(dbFilePath);
if (info.Length <= 20480)
{
File.Delete(dbFilePath);
repl.AddSubscription(System.Data.SqlServerCe.AddOption.CreateDatabase);
}
}
else
{
repl.AddSubscription(System.Data.SqlServerCe.AddOption.CreateDatabase);
}

primeConnection();

}
After the replication finishes, I dispose the replication object like so:





Code Block

void OnAsyncSynchronizeComplete(IAsyncResult asyncResult)
{

try
{
repl.EndSynchronize(asyncResult);
if (repl != null)
{
repl.Dispose();
repl = null;

}
if (ReplicationComplete != null) ReplicationComplete(this, true);
}
catch(Exception ex)
{
if (ReplicationComplete != null) ReplicationComplete(ex, false);
}

}

Then later, if I try to update, insert or delete to the database, the application will hang. I can read from it, but I cannot write. If I close the application down and open it back up without replicating, I will not get any lockups. It also will not hang up after any replications prior to the create replication. I think I am doing something wrong in the initial replication that is holding on to some connection to the DB causing it to lock up. Has anyone seen anything like this before?

Performance Monitors With SAN

Jan 25, 2005

We have recently moved our database to a SAN and I am trying to monitor performance. Does anyone know of a good way to monitor performance going to the SAN? I have been watching things like %Disk time and Avg Disk Queue Length, but does anyone know if these are acurrate when referring to a SAN? My %Disk Time is going up to numbers as high as 1200. The Disk queue length seems kind of low for seeing that high disk time as well.

Any help would be great.

Thanks much.

Concurrency Issue On A Single Database User For An Online Read/write Application

Aug 3, 2006

Hi to all DBAs,

I would like to ask if there will be a write and concurrency issue if i would create an online application with just one user connecting to the database, just like most open source php/mysql that can be downloaded

i.e
Setup 1. I will grant a single user that will connect to a database and will be set to a config.inc.php file and then create a table users (userid, username, password) and this table will be used for the application authentication and access control.

Setup 2. or is it much better to grant users that will connect to the database and have the table users for access control of the application?

to further illustrate my query:

Setup 1 would be:
###################Table: Users
user a@ipadd --> db1 --> userid mary --> myOnlineApp
user a@ipadd --> db1 --> userid john --> myOnlineApp
user a@ipadd --> db1 --> userid paul --> myOnlineApp


and Setup 2 would be:
#####################Table: Users
user mary@ipadd --> db1 --> userid mary --> myOnlineApp
user john@ipadd --> db1 --> userid john --> myOnlineApp
user paul@ipadd --> db1 --> userid paul --> myOnlineApp

will Setup 1 be enough if I will use SQL Server as database?

or Setup 2 is better user/database architecture?

This application will be online enrollment for a school with 16,000 students

very much appreciated for the feedbacks and suggestions

^_^x

Error 8525: Distributed Transaction Completed. Either Enlist This Session In A New Transaction Or The NULL Transaction.

May 31, 2008

Hi All

I'm getting this when executing the code below. Going from W2K/SQL2k SP4 to XP/SQL2k SP4 over a dial-up link.

If I take away the begin tran and commit it works, but of course, if one statement fails I want a rollback. I'm executing this from a Delphi app, but I get the same from Qry Analyser.

I've tried both with and without the Set XACT . . ., and also tried with Set Implicit_Transactions off.

set XACT_ABORT ON

TRANSACTIONS In SSIS (error: The ROLLBACK TRANSACTION Request Has No Corresponding BEGIN TRANSACTION.

Nov 14, 2006

I'm receiving the below error when trying to implement Execute SQL Task.

"The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION." This error also happens on COMMIT as well and there is a preceding Execute SQL Task with BEGIN TRANSACTION tranname WITH MARK 'tran'

I know I can change the transaction option property from "supported" to "required" however I want to mark the transaction. I was copying the way Import/Export Wizard does it however I'm unable to figure out why it works and why mine doesn't work.

Anyone know of the reason?

Analysis :: Find Amount Distribution Across Different Transaction Types Under Spend Transaction

Jul 27, 2015

I created a Calculated measure in cube something like this : ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent].&[SPEND],[Measures].[Transaction Amount]). To get only spend transactions. Now, I want to slice this measure with same hierarchy to find the amount distribution across different transaction types under spend transaction. But this query behaving like the measure doesn't have relation with measure.

you can think this as below query:
WITH
MEMBER SPEND AS ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent].&[SPEND],[Measures].[Transaction Amount])
SELECT NON EMPTY {SPEND} ON 0
,NON EMPTY ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent]) ON 1

Problem With SSIS Transaction...Transaction Scope

Jun 1, 2006



Hi,

I am having some problem with SSIS transaction. Eventhought I tried to imitate the concept that Jamie presented at http://www.sqlservercentral.com/columnists/jthomson/transactionsinsqlserver2005integrationservices.asp

. My workflow is as followed

*********************************
For Each ADO.Record in Oracle (transaction=not supported)

If (Certain_Field_Value = 'A')


Lookup Data in SQL DB with values from Oracle (transaction=not supported)

DO Sequence A (Start a Transaction , transaction=required)


INSERT/UPDATE some records in SQLDB(transaction=supported)
Finish Sequence A ( transaction should stop here)
UPDATE Oracle DB ( Execute SQLTask, transaction=not supported)
If (Certain_Field_Value = 'B')


Lookup Data in SQL DB with values from Oracle (transaction=not supported)

DO Sequence B (Start a Transaction , transaction = required)


INSERT/UPDATE some records in SQLDB (transaction=supported)
Finish Sequence A ( transaction should stop here)
UPDATE Oracle DB ( Execute SQLTask, transaction=not supported)
If (Certain_Field_Value = 'C')

------------
------------
End ForEach Loop
*************************************
My requirements are that I want separate transaction for each Sequence A, B, C, etc... If Sequence A transaction fails, the other should still be continuing with another transaction.
But I am getting an error regarding the OLEDB Error in next Task (e.g in Certain_Field_Value = 'B') "Lookup Data in SQL DB with values from Oracle ", the error message is ".......Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction. ".
What is it that I am doing wrong?

New Transaction Cannot Enlist In Transaction Coordinator (was Please Help...)

Apr 18, 2005

Hi all,

In my ASP application, I've been using this code:

----------------------------------------------
dim conn, connectionstring

connectionstring= "Provider=SQLOLEDB.1; Data Source = blahblah; Initial Catalog = abc; User Id = osss; Password=xxx"

set conn = server.CreateObject("adodb.connection")
conn.open connectionstring

----------------------------------------------

It's just basically to set up the connection to the SQL server, it works on my other pages, but on a few pages, the last line (conn.open connectionstring) triggers this error:

"Microsoft OLE DB Provider for SQL Server error '8004d00a'

New transaction cannot enlist in the specified transaction coordinator. "

I've never encountered this error before and I couldn't think of any solution... please help!!!

Thanks so much,

BEGIN TRANSACTION COMMIT TRANSACTION Help

Sep 24, 2007

I had thought that if any statement failed within a BEING TRANS .. COMMIT TRANS block, then all the statements would be rolled back. But I am seeing different behavior (SQL Server 2000 8.00.2039)

For instance, run these statements to set up a test:
--DROP TABLE testTable1
--DROP TABLE testTable2
CREATE TABLE testTable1 (f1 varchar(1))
CREATE TABLE testTable2 (f1 varchar(1))
CREATE UNIQUE INDEX idx_tmptmp ON testTable1 (f1)
insert into testTable1(f1) values ('a')

So table testTable1 has a unique index on it..

Now try to run these statements:

--DELETE FROM testTable2
BEGIN TRANSACTION
insert into testTable1(f1) values ('a')
insert into testTable2(f1) values ('a')
COMMIT TRANSACTION

SELECT * FROM testTable2


..the first insert fails on the unique index.. but the second insert succeeds. Shouldn't the second insert roll back? How can I make two operations atomic?
