SQL MOBILE Synchronization Problem!!!
Jun 15, 2007
Hi all!
I've been trying to solve this issue searching other posts but nothing seems to solve my problem.
Background:
I developed an app in visual studio 2003 for an iPAQ. This app. needs to synchronize the database in the iPAQ whith one in the server. My server was a local machine with SQL Server 7. With some problems but I made it run. I used SQLCE 2.0 and at the begining a previous model for for the iPAQ with other OS. Then I find out that in Windows mobile 5.0, sql ce has to be installed manually.
So:
Windows 2000
SQL Server 7
SQLCE 2.0
Windows Mobile 5.0 (and one previous)
All the required configuration as below
Problem:
I have a new machine and I have to configure it for the same process:
Windows XP
SQL Server 2000 (Service Pack 4 and Replication components)
.Net Framework 1.1 (although I had .net framework 2.0 installed .net asked for it)
SQL 2005 Mobile Edition
SQL 2005 Mobile Edition Server Tools
.Net Compact Framework 2.0
ActiveSync 4.5
IIS installed and configured
IUSR_XXXX created and with system administrator rol and dbo access to the database
Publication created and with permissions to IUSR_XXXX
Snapshot folder created and shared with permissions for IUSR_XXXX (read and write)
Virtual directory created and working:
http://<ip adress>/<snapshot folder>/sqlcesa30.dll works fine in IE
same url working in the iPAQ
Error:
When I use replicator.Synchronize() I get the next error:
Error: 80072F76
HResult -2147012746
NativeError 28035
Message "Header information is either corrupted or missing. [,,,Header name,,]"
PLEASE HELP!!!!
Thank you in advance

Hi,
We have a strange problem synchronizing data with mobile device. Replication is done with Integeration Services packages which replicates data to two tables in replication database. Those two tables are also the only tables in replication database.
When mobile device is synchronized for the first time, all the required data is transfered to mobile device as it should. But, if there are new lines to be added to replication database when integration service packages are ran (and also published), those new lines are not synchronized to mobile device! What makes it strange, if I add new lines to replication database manually, those are synchronized to mobile device correctly.
This could be an issue with my replication/publication but I just have no idea what it is. Any help is much appreciated!

Hi all,
Some time ago, you helped me to solve some issues with my app. in an iPAQ and it was working just fine connecting by modem in a test environment. Now in a new server, production environment, it does not work anymore.
I have done everything I was supposed to, but can´t get it to work.
I have the next error: "A request to send data to the computer running IIS has failed. For more information see HRESULT".
HRESULT error is something like -2147120897 and I've searched for this and it says it's a timeout error, but I have increased the timeout in the SQL Server and in IIS service but did not work.
I have my publication working, the snapshot folder created and with permissions, the sqlcesa30.dll working just fine from my iPAQ and connecting by modem. IUSR_<server> user with full access to snapshot, database, publication. ActiveSync installed. I think everything else working just fine!!
Please, can anyone help me???If you need my server and iPAQ config please ask me.
Thank you in advance!!!

I am creating a mobile application in which i am implementing data synchronization through merge replication method as per the step by step procedure given in the following link:-
http://msdn2.microsoft.com/en-us/library/ms171908.aspx
I am using SQL server Mobile Edition which is included in SQL server 2005 in this application, but the application suggests to use SQL server Compact Edition. I was able to successfully create the publication, but not able to run the sqlcesa30.dll file of the created virtual directory in the internet explorer. Is this problem because of i'm not using SQL server Compact Edition? and also let me know if i use SQL server Mobile Edition, do i need to install its Server Tools? If yes, please give me the link to download the tools needed.
Reply Soon.

I create a distributed database for mobile application. I replicate a table that distribute on mobile device. I follow instruction how to create distributor, publication, replication, web synchronization, and subscriber database. I have done fine for synchronization between mobile database into desktop database (in this case SQL Server 2005 Standard Edition). But the problem is how can setup publication so it can bidirectional, not only from mobile database into desktop database, but also from desktop database into mobile database. So in the mobile database can have same data with desktop database even on mobile database lost some old data.
Its like data exchange between both engine. Desktop and mobile have same data. For filtering I can put filter on the desktop server for replicated table, so don't worry how I split the data.
Thanks a lot.

I have something called Configure Web Synchronization Wizard under my SQL Server 2005 Mobile Edition on my XP machine. My problem is that I need to install it on a Windows 2000 machine and I can't find the installation package for it. I installed SQL Server 2005, which installed SQL Server 2005 Mobile Edition, but I didnt' get the wizard. I also installed Visual Studio 2005.
Anyone know where it is?

Hi Everyone
I am at the stage of architecting my solution
My goal is to develop the system on a windows application and pda
There is a central server which will create a publication called inventory
The laptops which host the windows application will be subscribers to the central server using merge replication
The client now wants the PDA using SQL Mobile to synchronize with the local subscirber database on the laptop using active sync. They dont want to do it via WIFI to the IIS Server at the central server
I have been reading for days and I am still unsure whether this is possible to do.
I know Appforge provide a conduit for palm to access synchronization but not local sql databases
I would appreciate your help immensley

Hello,
I plan to use :
- SQL Server on server
- SQL Server Express on notebooks
- SQL Mobile on Windows Mobile 5.0 devices.
How can I create a replication between SQL Express and SQL Mobile ? SQL Server express cannot act as a Publisher server.
In this post a Senior Program Manager says It is possible but I don't find how to :

Hello everybody,
There is some strange behaviour i've recently noticed while watching synchronization progress in Replication Monitor on SQL 2005 Server Standard with merge replication configured. The merge process seems to repeat several times.
This is the initial synchronizaion (reinitalization at the subsciber). Client is using Microsoft.SQLServer.Replication objects from .net framework assemblies.
The synchronization starts normally (status is "Running"). The last message of selected session box shows (among other messages): "Beginning evaluating partial replication filters" then "Finished evaluating partial replication filters" and finally "Merge completed after processing xxx changes... etc." after a few seconds. Status changes to "Completed" and then... the merge process starts again!! "Beginning evaluating partial replication filters" etc. And this repeats about 15-20 times.
And so whole process takes about 15 minutes instead about 45 seconds to complete initial synchronization. The number of changes is "Merge completed after processing ..." never change since the first such message.
Is this some bug in web synchronization or some invalid configuration setting? Why does merge process repeat itself so many times??
Please help, thanks in advance.

Dear ppl,
I am writing an application for a device (MDA Pro T-Mobile) having Windows Mobile 5.0 using
-MS .NET Compact Framework 2.0 SP-1
-SQL Mobile 2005.
-VS 2005 .NET
The application uses Merge Replication. The error occurs in the Synchronise() Method of the SqlCeReplication object.
"SQL Server Mobile encountered problems when opening the database."
repl.AddSubscription(AddOption.CreateDatabase);
repl.Synchronize();
I don't understand why I am having this error. It does create the database on AddSubscription() method but it is failing opening the database on Synchronise(). I have also tried uninstalling and then reinstalling all the SQL Mobile components in the following order.
-sqlce30.wce5.armv4i.cab
-sqlce30.repl.wce5.armv4i.cab
-sqlce30.dev.ENU.wce5.armv4i.cab
However, when i run this application on a device(Dell X50 AXIM) with Pocket PC 2003, it runs fine creating the database and sysnchronising it.
The target platform for the project is Windows Mobile 5.0 Pocket PC SDK.
Does any one have any clue what could be the problem ?
Regards
Nabeel

I am migrating a pocket PC application from VS 2003 to VS 2005 and a few weeks ago I hit the following problem when replicating
A SQL Mobile DLL could not be loaded. Reinstall SQL Mobile. [ DLL Name=sqlceca30.dll]
Scanning forums for help I saw that other people had had this problem and one
http://www.eggheadcafe.com/aspnet_answers/NETFrameworkCompactFramework/Feb2006/post25814466.asp
suggested that this problem could be circumvented by getting the replication object early and then continuously using the same object for subsequent replications.
I did this and it works a lot better now but ever so often I get another error which is
Native Error 28559 SQL Mobile encountered problems when opening the database
My only option at this point is to stop and start the application which cures the problem.

Hello,
I am developping a non-managed C++ application for PocketPC using a SQL Server mobile database.
The application is compiled for PocketPC 2003 and uses SQL Server Mobile v2. I use Visual Studio 2005. But I need to compile the application for Windows Mobile 5.0 devices. So I installed the WM5 SDK and had the WM5 into my project configuration.
The "ssceoledb.h" which I include incluses the "transact.h" file. But my problem is that this file is only provided with the PocketPC 2003 SDK and not in the WM5 SDK.
So I cannot use the WM5 configuration project with SQL Server. I also tried with the last SQL Server Mobile 2005 (ie v3.0) and the "ssceoledb30.h" also includes "transact.h".
Did I miss something to install ?
Do you know how I can resolve the problem ?
By advance, thank you for any answer.

Using MS VS 2005 (incl SQL Server Mobile)
MS Pocket PC 2005 SDK
I am working on a project that builds for Pocket PC on both Mobile 2003 and Mobile 5. The project uses/will use SQL Server Mobile to store local data.
Project created from new with support for both platforms. I include required header files ssceerr30.h and ssceoledb30.h.
Project builds fine in WM2003 configuration, release and debug.
When I build for WM5 the compiler cannot find the header file transact.h. This is included from within ssceoledb30.h. Same as under WM2003.
In WM2003 configuration if I highlight the ssceoledb30.h include in Visual Studio and open the header, it takes me to <Visual Studio dir>SmartDevicesSDKSQL ServerMobilev3.0. I then locate the include for transact.h and do the same, which takes me <Visual Studio dir>SDKPocketPC2003include. The file exists.
If I repeat the above 'browsing' under the WM5 configuration, ssceoledb30.h takes me to a different copy in the WM5 SDK directory. There is no diff between the file here and the other copy used by WM2003. If I attempt to open transact.h - file does not exist.
Fix (which I'm not too sure about, i.e. is it OK?) - If I copy transact.h to the WM5 SDK directory, the project builds.
Why has transact.h disappeared from WM5 SDK?
I can find no ref's to this problem anywhere. Is my installation of the WM5 SDK corrupt? What else could I be missing?
Is there a sample for SQL Server mobile (like the NorthwindOLEDB sample) that comes configured to build for WM5?

I receive error 25123 on my PPC (audiovox 6600) in a reproducable way (usually) with .net 2.0 application that is using SQL CE that I wrote:
Open the application
Connect to the database
Close the applicaton
Re-Open the application
Connect to the database <-- Error occurs
I will also receive the error if my application isn't the first application launched (or very close to the first to launch).
I don't believe it's a memory issue as according to the memory manager I have plenty of memory:
At boot up only start screen items loaded: 18.46 Used 49.89 Free
Launch Resco File Explorer to click EXE: 19.18 Used 49.18 Free
Launch my application (no DB connection): 23.64 Used 44.71 Free
Connect to the DB and do select count(*) from a table with 0 rows: 26.27 Used 42.08 Free
Close the application (this.Close() on the form: 19.38 Used 48.97 Free
Relaunch App and connect to DB receive error: around 38 Used around 30 free
I was unable to reproduce the issue right now while typing this message, the last sets of numbers are from memory, and include other applications that are currently running.
The only way I have to get SQL CE to load again is to soft reset the PPC. If the application is able to connect to SQL CE at least once it is fine up till I close it and re-open the application. So it either connects and runs great, or it can't connect at all.
Any help in resolving this issue would be greatly appreciated.

Hi folks, I'm new to Windows Mobile progamming, and new to this forum. Apologies in advance if I'm asking a boneheaded question, but I've done searches and can't find anything directly applicable to my problem.
I'm currently walking through the published MS tutorial in setting up an SQL Server 2005 Mobile application that subscribes to a publication on SQL Server 2005 to exchange information.
I've gotten almost all the way through... successfully set up the server components, creating the publication, etc. On the mobile side, I've been able run the cab files to install the SQL Mobile components and to create the project, add the reference to the dll, and instantiate an engine object. It compiles.
The step in the tutorial after that, though, where you specify the data source from the "data" menu, I've got a problem. When I try to use the "new connection" dialog from choosing the data connection, "MS SQL Server Mobile Edition" doesn't show up as a choice. I've tried choosing any of the other combinations, and in teh subsequent "Connection properties" section my database, SQLMobile (as in their sample) is available, but I get an error when I choose it and click OK. Clicking on "Test Connection" gives me a connection successful message.
My guess is that something about the Mobile server side components is not installed correctly on my development machine, but honestly I have no idea how to begin to fix it. Has anyone seen this problem before and know how to resolve it?
Your time and any knowledge sharing is greatly appreciated.
Thank you,
-Dana

This is a great tutorial and it's a shame one of the more important steps was missed.
In the €œCreate the snapshot user€? section you you find the steps to create the snapshot_agent account. Then in the €œCreate the snapshot folder€? section you find the share and folder permissions. However, at no point do the instructions advise you about adding the snapshot_agent to the SQL Server Logins. The result is that agent cannot perform the initial snapshot but you won't find this out until 50 steps later after Step 10 in the section €œCreate a new subscription".
To get back on track, openthe Object Explorer's Security section and add the snapshot_agent to your logins. Then using the "User Mappings", set an appropriate level for the SQLMobile database role. Once completed you then need to run the agent.
Right-click the SQLMobile publication you created and select "View Snapshot Agent status". From that dialog you can select "Start" to run the agent. When it completes, you can return to the tutorial section "Create a new subscription" and continue with the tutorial.

I am studying the tutorial in SQL Server 2005 Mobile Edition Books Online, and the topic is Creating a Mobile Application with SQL Server Mobile. I have got a problem when creating a new subscription after created a new SQL Server Mobile database. And the problem is shown below:
New Subscription Wizard
- Beginning Synchronization (Success)
- Synchronizing Data (100%) (Error)
Messages
* Failure to connect to SQL Server with provided connection information. SQL Server does not exist, access is denied because the IIS user is not a valid user on the SQL Server, or the password is incorrect.
HRESULT 0x80004005 (29061)
* 無法完æˆ?作æ¥ã€‚
- Finalizing Synchronization (Stopped)
- Saving Subscription Properties (Stopped)
Before I have met this problem, I have finished all the task. And I can browse the localhost web site by using anonymous account even I use internet explorer or browse the directly in IIS.
Does anyone can solve it?? Thank you very much~~~

Hi:
When I try and connecto to SQL CE I always get an invalid operation exception. I"m afraid that I did not follow the proper install for Orcas Beta 2. I can't remember if I was supposed to uninstall SQL Mobile 2005 first or not.
All I know is when I try and use my SQL CE I can't connecto to a DB / sdf file ?
Any help would be appreciated I"m just starting to use SQL CE.

Hello guys!
I went through the bunch of documentation pages about configuring the one for providing web subscriptions.
The most usefull for me were:
Security Architecture for Web Synchronization
How to: Configure an IIS Server for Web Synchronization (SQL Management Studio)
How to: Configure a Subscription to Use Web Synchronization
Topologies for Web Synchronization
Securing the Publisher
Subscribing to Publications
Mssubscription_properties (Transact-SQL)
How to: Configure a Subscription to Use Web Synchronization (Replication Transact-SQL)
sp_addmergepullsubscription (Transact-SQL)
Web Synchronization for Merge Replication
But I still have questions about it. If you could help me with small notes about subscribing to web based merge publication I would really appreciate that!
I believe, I just need a bit of clarification. The target setting is simple as it is: a client should connect to the our hosting server via HTTPS and update his pull subscription on demand by running .NET application.
Avoiding the server part, are the following steps correct and enough to accomplish what I need?
1. To create subscription, should I use the script:-- This script uses sqlcmd scripting variables. They are in the form-- $(MyVariable). For information about how to use scripting variables -- on the command line and in SQL Server Management Studio, see the -- "Executing Replication Scripts" section in the topic-- "Programming Replication Using System Stored Procedures". -- Publication must support anonymous Subscribers.-- Execute this batch at the Subscriber.DECLARE @publication AS sysname;DECLARE @publisher AS sysname;DECLARE @publicationDB AS sysname;DECLARE @websyncurl AS sysname;DECLARE @security_mode AS int;DECLARE @login AS sysname;DECLARE @password AS nvarchar(512);SET @publication = N'AdvWorksSalesOrdersMergeWebSync';SET @publisher = $(PubServer);SET @publicationDB = N'AdventureWorks';SET @websyncurl = 'https://' + $(WebServer) + '/WebSync';SET @security_mode = 0; -- Basic Authentication for IISSET @login = $(Login);SET @password = $(Password); -- At the subscription database, create a pull subscription -- to a merge publication.USE [AdventureWorksReplica]EXEC sp_addmergepullsubscription @publisher = @publisher, @publication = @publication, @publisher_db = @publicationDB, @subscriber_type = N'anonymous'; -- Add an agent job to synchronize the pull subscription. EXEC sp_addmergepullsubscription_agent @publisher = @publisher, @publisher_db = @publicationDB, @publication = @publication, @distributor = @publisher, @job_login = @login, @job_password = @password, @use_web_sync = 1, @internet_security_mode = @security_mode, @internet_url = @websyncurl, @internet_login = @login, @internet_password = @password;GO
What is @job_login parameter here? As I understand, I will not run SQL Agent job as our client uses MS SQL Server 2005 Express. And I do not want to run it as we will provide a client with .NET application for performing synchrinization on demand
Parameter @publisher means full SQL Server instance name? For example, MYMACHINEMSSQLSERVER?
What user will be used to connect to the distributor and to the Publisher? Will it be @internet_login?
Do I need running sp_addmergepullsubscription_agent if I€™m going to use the following .NET application code to synchronize over the Internet?
2. To perform synchronization with our hosting servers, should a client use the following code?
// Define the server, publication, and database names.
string subscriberName = instanceName;
string publisherName = instanceName;
string publicationName = "AdvWorksSalesOrdersMerge";
string subscriptionDbName = "AdventureWorksReplica";
string publicationDbName = "AdventureWorks";
string hostname = "adventure-works\garrett1";
string webSyncUrl = "https://" + instanceName + "/SalesOrders/replisapi.dll";
// Create a connection to the Subscriber.
ServerConnection conn = new ServerConnection(subscriberName);
MergePullSubscription subscription;
MergeSynchronizationAgent agent;
try
{
// Connect to the Subscriber.
conn.Connect();
// Define the pull subscription.
subscription = new MergePullSubscription();
subscription.ConnectionContext = conn;
subscription.DatabaseName = subscriptionDbName;
subscription.PublisherName = publisherName;
subscription.PublicationDBName = publicationDbName;
subscription.PublicationName = publicationName;
// If the pull subscription exists, then start the synchronization.
if (subscription.LoadProperties())
{
// Get the agent for the subscription.
agent = subscription.SynchronizationAgent;
// Check that we have enough metadata to start the agent.
if (agent.PublisherSecurityMode == null)
{
// Set the required properties that could not be returned
// from the MSsubscription_properties table.
agent.PublisherSecurityMode = SecurityMode.Integrated;
agent.DistributorSecurityMode = SecurityMode.Integrated;
agent.HostName = hostname;
// Set optional Web synchronization properties.
agent.UseWebSynchronization = true;
agent.InternetUrl = webSyncUrl;
agent.InternetSecurityMode = SecurityMode.Standard;
agent.InternetLogin = winLogin;
agent.InternetPassword = winPassword;
}
// Enable agent output to the console.
agent.OutputVerboseLevel = 1;
agent.Output = "";
// Synchronously start the Merge Agent for the subscription.
agent.Synchronize();
}
else
{
// Do something here if the pull subscription does not exist.
throw new ApplicationException(String.Format(
"A subscription to '{0}' does not exist on {1}",
publicationName, subscriberName));
}
}
catch (Exception ex)
{
// Implement appropriate error handling here.
throw new ApplicationException("The subscription could not be " +
"synchronized. Verify that the subscription has " +
"been defined correctly.", ex);
}
finally
{
conn.Disconnect();
}
What does HostName parameter use for? What is that host? Subscriber€™s machine name instance name? Or Publisher€™s? Or Distributor€™s?
Why parameters PublisherSecurityMode and DistributorSecurityMode have value SecurityMode.Integrated? How it is used in the replication model for web synchronization? As I understood from the documentation, client (Merge Agent) should connect to the Subscriber, get the changes, connect to hosting server via HTTPS and perform transactions through the SQL Server Replication Listener, thus the internet login to the IIS should be used to perform all the operations on hosting server side? The same internet login will be used to get snapshot from UNC share?
If I€™ve chosen to use FTP to provide with snapshots, should I then provide ftp parameters to sp_addmergepullsubscription_agent stored procedure or they will be used automatically by ISAPI filters on hosting server?
Thank you.

Hello,
I'm having to build a smart client application that works with an offline sql express database on the client. And works with several types of databases - that may be configured to work as a central server. The list includes the sql server family including 2000, 2005 and express and also IBM DB2.
I have to address some rather complex merge replication scenarios. By Merge I mean the ability to deal with handling and synchronization of bi-directional changes. More specifically changes to data may be made to any database in the system. either local or central.
I'm afraid, I cannot use sql replication in a heterogenous mode for several reasons. Some being - the database is being auto attached on the client, the application is expected to live up to the 'low impact' install ideology and should not need any major configuration etc.....
Are there any recomended approaches/Ideas one may use to acheive replication. Any links/information/ideas will be great.
Thanks,
Avinash

Hi!
I'm developing a Windows Mobile solution (Pocket PC Win 5-6). I have Sql Server CE on the device and I use RDA (Remote Data Access) to pull the tables to the Sql Server CE. I use RdaTrackOption.TrackingOffWithIndexes so I can Alter the table design. Then I use the function SubmitSql to push back my changes. On the server I have a table for example Customers, it has a column called CustomerId with identity(1,1). Let's say the highest Id is 100 and the lowest is 50, when I add a record in the Sql Server CE it gets CustomerId = 1 then next one 2 etc which means identity is working but does not continue after 100. I don't need to use the CustomerId when I push my data back because I have sql syntax taking care of @@IDENTITY when inserting new records. Anyone who knows why it begins on 1 and not 101?

I am a complete novice so I would appreciate any help or suggestions.
I have two databases : 1 development DB, 1 production DB (both are SQL Server)
I make changes to development DB on a daily basis and I need a method to bring these changes across to production DB.
Currently I query the selected table in the development DB and write the DataSet to an XML file.
##
objDataSet.WriteXml(Server.MapPath("xDataDictionary.xml"))
##
Once I go to client site (where production DB is located) I want to generate a DataSet (which I am able to do) and compare this DataSet with the DataSet created when I read in the XML file.
##
'read in XML file
XMLDataSet.ReadXML(Server.MapPath("xDataDictionary.xml"))
##
There is a unique identifier in the table and XML file called 'FieldID'.
What I need to do is compare DataSet (from Production DB) with DataSet from XML file.
If there is a 'FieldID' in the DataSet from XML file that IS NOT in DataSet from ProductionDB I want to insert this node/row into the database.
Any suggestions?

I was wondering if anyone knows if there is any software available or
if it is easy to implement the following.
We are running a SQL Server database locally in house and also have
the exact same database running on a hosted webserver. The data
changes on both versions of the database daily and what we need to do
is figure out a simple easy / cheap way to have the two databases
synchronize with each other every evening so that the data is exactly
the same every morning.
I would appreciate any input.
thanks
