Merge Replication Between SQL Server 2005 And SQL Mobile

Oct 18, 2007

Hi,

I'm currently investigating the feasibility of having SQL Mobile on a number of devices running Windows CE. These devices will have to synchronize with the server (either using merge replication or RDA) over GPRS. The problem I have is that some of these devices will never be online. Is there are a way of synching these offline devices? The model I had in mind was using a USB key (or some other storage device) to download the latest updates from an online device and transferring this data to the offline device, and vice versa e.g. from offline to online and then merging. Is this feasible?

Thanks

SQL Server Mobile 2005 Merge Replication Problem On Windows Mobile 5.0

Aug 8, 2006



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

How Do I Measure Bandwith Usage For Merge Replication SQL 2005 To Sql Server Mobile 2005?

Jan 24, 2007

Hi,

Is there any way to measure bandwith usage during merge replication between sql server 2005 and sql server mobile 2005 running on a cradled wm5 mobile device.

Attaching the windows performance monitor to the network connection established over usb would work although I was wondering if there was something specific for this case integrated into Sql server 2005 / sql server mobile 2005 / Sql server management studio / third party tools that i could use ?

thnx,

pdns.

Help Needed In Merge Replication, SQL Server 2005 Mobile Edition And VC# 2005

Apr 10, 2008

I have written following code in my application

I just want to display all the data of a Single table into a Data Grid, I know that we can drag and drop the table on to a form and datagrid is generated, but here I want to retrive those values through my code, how should i do that

I am getting following errors while running the program
Error 1) Error No. 28037, MS SQL Server 2005 Evrywhere Edition
Error: A request to send data to the computer running IIS has failed. For more information see HRESULT

Error: The specified table does not exist [ JobLists ].

Can anybody please tell me, where I went wrong ??? In this code anywhere else????

Note: While adding a Data Source of SQL Server 2005 Mobile Edition, I have added that .sdf file into my project, thats why I have written the Data Source as : .DbFile.sdf

Merge Replication 32-bit IIS - 64-bit SQL Server 2005 -Windows Mobile 5 Device

Nov 15, 2006

We have setup a 32-bit IIS server on a 32-bit machine. Installed necessary SQL Server components (32-bit replication components). We have installed SQL Server 2005 64-bit SP1 with latest hotfixes on a 64-bit machine.

On the Mobile device we installed SQL Server 2005 Mobile.

When we start mergereplication the problem we have is error 28009 (An instance of the SQL Server Reconciler cannot be created) on the mobile device. I read allot about it, but still have a questetion.

Should this work?

I found the doc: SQL Server 2005 Upgrade Technical Resource Guide:
Note: If your upgrade involves SQL Server CE subscribers, you must perform additional actions on the IIS server. You will need to install SQL Server 2005 client connectivity components along with SQL Server Mobile Edition components on the IIS server. You will also have to replace sqlcesa30.dlll, sqlcerp30.dll, and all the replication components on the IIS server.

From this I conclude it should work or is the doc in error?

If it does not, what can we do?

32-bit SQL Server 2005 on the 64-bit machine should work. (Can a 64-bit SQL Server 2005 run alongside 32-bit SQL Server 2005?).

Beste regards,
Hans Mank

Merge Replication With SQL Mobile 2005

Apr 25, 2006

We are using SQL 2005 (SP1) and mobile agents with SQL Mobile. We are seeing an excessive number of updates after a device's database is reinitialized. My understanding was that if I generate a new snapshot or reinitialize all subscriptions (from the server), the devices would only get what the database looks like right now (inserts only) after syncing and/or reinitializing, but they are actually getting the right number of inserts and a huge number of updates in Replication Monitor. Any ideas?



Thanks!

SQL 2005 Mobile Merge Replication Size Limits?

Feb 8, 2006

I am in the process of testing a SQL 2005 Std x64 server with merge replication using Windows Mobile 5.0 clients and SQL 2005 Mobile. The test DB is a copy of the currently active DB, but has been expanded to include some new tables to support planned application functionality extensions.

Once the publication exceeds 97 Articles, the error is thrown that "The buffer pool is too small or there are too many open cursors". If I drop one article everything is fine. I ran a test with dummy DB that had 100 blank tables, and this initialized just fine on the client. The additional articles I am publishing (the 98th table) is also empty, but it throws the error anyway.

Is there a limit on the total size/number of changes that can be sent? Since I have run tests sending over 64,000 changes to a client during initialization this does not seem to be the case (I am only attempting a little more than 9,700 changes on this initialization).

Some other ideas that have been tested without success are to stop the user triggers from propagating, and toggling the AWE setting for SQL. The Replication Monitor does say the client completes replication, and it seems to choke at the very end of completing replication when it attempts to write to the tracking tables. The last successful action is sys.sp_MSadd_merge_history90, and it appears to be acting on the last table added to the publication.

There does not appear to be a limit on the number or articles, since I can publish more articles in a dummy DB than I am able here, so it seems to be something to do with size. Any information would be helpful, this is a very frustrating issue. Thanks!

High CPU Utilization On Merge Replication With SQL 2005 Mobile

Jan 10, 2006

I have a question for anyone who mas some tips/pointers for optimizing SQL merge replication publications. 

The front end web server is running IIS 6.0 on Windows 2003 x86 Server Standard (Server A).  The back end database server is running SQL 2000 Standard on Windows 2003 x86 Standard (Server B).  The merge replication clients connect via HTTPS over the Internet from a custom C#.NET 2005 application using SQL 2005 Mobile running on Windows Mobile 5.0 (Client).

The publication itself has several filters on it.  The entry point uses the user's Windows username to start the filter.  Based on the user, it then filters the records in multiple tables.  There are 68 articles and 44 filter statements.  The filters extend multiple layers deep, in other words they are not all filtering off the HOST_NAME() variable, some tables filter from records in tables that filter from the HOST_NAME() variable.  The publication is set to minimize data sent to the clients, and considers a subscription out of date if it has not synced in the last 4 days.  All the rowguids are indexed as well.

There are approximately 35 clients actively using the application at any given time.  On average, a client will initiate a merge replication 3-4 times per hour from 8am-5pm.  Generally, a sync will take between 10 seconds and 2 minutes to complete, with most of them being around 30 seconds on average. 

When a client starts a sync, there is a spike to about 50% on the server's CPU graph.  If multiple clients attempt to sync at the same time the CPU utilization can be pushed to 100% for extended periods (more than 30 seconds). 

I recently completed a project to increase the bandwidth available to the clients, and plan to reduce the number of filters significantly (although this will obviously increase the amount of data going to the clients and the storage needs on the individual devices).  I also plan on changing the setting to not minimize the amount of data sent to the clients.

Having said all that, does anyone have any information about how to further optimize merge publications to mobile clients?  The next publication will be on SQL 2005 x64 Standard if I can solve the issues in the text environment.  I would like to enhance the publication as much as possible to make the end user experience better than it currently is.

Thanks!

SQL Mobile 2005 Merge Replication With SQL 2005 X64

Jan 10, 2006

I am having trouble with getting Merge Replication up with a new SQL 2005 x64 Server.  I already have it running smoothly with SQL 2005 Mobile and SQL 2000, but I want to migrate the backend to SQL 2005.

There is a front end server running IIS 6.0 on Windows 2003 x86 Standard (Server A) with SSL required and Basic Authentication set as the only authentication method (default Domain and Realm are also set).  The backend server is running SQL 2005 x64 Standard on Windows 2003 x64 Standard (Server B).  The mobile devices are running Windows Mobile 5.0 with SQL 2005 Mobile (Client).

From both a standard Windows XP workstation (IE) and the Client (PIE) I can browse to the HTTPS site on port 444 for the sqlcesa30.dll on Server A and get a response in normal and ?diag modes.  The ?diag gives success in all but the 8.0 Database Reconciler (I didn't install the SQL 2000 replication components on Server A, my understanding is they should not be needed).  Sql Server Module Versions are as follows: sqloledb.dll - 2000.86.1830.0, 9.0 replrec.dll - 2005.90.1399.0, 9.0 replprov.dll - 2005.90.1399.0, 9.0 msgprox.dll - 2005.90.1399.0.

The publication on Server B is enabled for Web Synchronization and the Snapshop Agent has run.  There are no reported errors on that side.

Since I ran into issues getting synchronization to run I have opened up permissions fairly wide in this test environment.  The PAL and the Database both have the user I am attempting to sync with listed (I am using the Administrator account in the test domain).  I have opened full rights on the Snapshot share on Server B to Everyone (both NTFS ACL on the directory and the Share permissions).  The virtual directory on Server A containing the sqlcesa30.dll has also been opened very wide, and the Application Pool does have access to it.

The Client is running a custom C#.NET 2005 application.  With the exception of changes to set the application to sync with the Server A/B duo instead of the production servers, this application is identical to the code currently being used in production with SQL 2000 Standard.

The persistent error that I am getting from the Client being thrown by SQL 2005 Mobile when I attempt to sync is "An instance of the SQL Server Reconciler error object cannot be created.  Try reinstalling the replication components."

SQL 2005 Mobile components on Server A are set to Logging Level 3 but not returning any errors that I can see to troubleshoot with.  All replication components appear to be installed and operational, although I have re-installed them.

Besides the obvious question of how to solve the error listed above, is there an issue with am x85 front end IIS 6.0 server talking to an x64 back end SQL 2005 server for merge replication over HTTPS with Windows Mobile 5.0 clients running SQL 2005 Mobile?

Based on everything I have read off the MSDN Forums, MSDN articles, BOL, log files, and web searches it seems like I should have an operational synching topology, however clearly I have missed something because I have yet to get a successful subscription through to the publication.

Any insight/enlightenment would be greatly appreciated, this seems to be a very narrow and specific area of replication and mobility and information is relatively sparse from my experience so far.

Thanks!

Locking Up After SQL Server Mobile Merge Replication

Nov 9, 2007



Hi ,
I would like to get your advice in an issue that I am facing regarding merge replication.
The flow is like:
1) User enter his login name and password.
2) Host_name is set as the login name that the user enters.
3) Based on the HOST_NAME property after filtering user gets the records relevent only to him
(Differnet subscriber may use same mobile device).

4) He make some changes in the local sdf according to the business logic.
5) The application Syncs with server on the next login session.

My issue is when I am trying to run the application in emulator exactly at the sdf updating part the application terminates.
Error mess: Connection to Remote Device has been lost.....
If I execute the same sql insert query it works om the local sdf and master database.
Emulator used where Pocket PC 2003 SE and Windows Mobile 6 classic emulator.
I have installed 1) Visual Studio 2005 SP 1 2) net compact framework SP2.

When I comment all the code related to Sync ,application works witout any issue.
And the same application works in my "I mate kjam".

The code that I use is given below:
==========================================================================

public void Sync(string hostname, int newsub) // Parameters for HOSTNAME and flag to denote new user or existing //user.

{

SqlCeReplication repl = new SqlCeReplication();

repl.InternetUrl = @"http://231.000.000.211/Merge/sqlcesa30.dll";

repl.Publisher = @"SERVER";

repl.PublisherDatabase = @"Merge";

repl.PublisherSecurityMode = SecurityType.DBAuthentication;

repl.PublisherLogin = @"sa";

repl.PublisherPassword = @"password";

repl.Publication = @"Merge";

repl.Subscriber = @"MergeSub";

repl.HostName = hostname;







repl.SubscriberConnectionString = @"Data Source=""Program FilesMerge.sdf"";Max Database Size=128;Default Lock Escalation =100;";





try

{

if (newsub == 0)

{

if (File.Exists(@"Program FilesMerge.sdf"))

{

File.Delete(@"Program FilesMerge.sdf");

}



repl.AddSubscription(AddOption.CreateDatabase);

repl.Synchronize();

repl.Dispose();

MessageBox.Show("newuser sync Done");

}

else

{

if (!File.Exists(@"Program FilesMerge.sdf"))

{

repl.AddSubscription(AddOption.CreateDatabase);

repl.Synchronize();

repl.Dispose();

MessageBox.Show("FirstSync Done");

}

else

{

repl.Synchronize();

repl.Dispose();

MessageBox.Show("SameuserSync Done");

}

}

=================================================================================
Please advise......

Using Row Filtering In SQL Mobile Merge Replication

Oct 25, 2007

Hi,,

I understand that it is possible to set filters dynamically using functions 1) SUSER_SNAME() 2) and HOST_NAME().
SUSER_SNAME() returns the login credentials used in the subscritption.
HOST_NAME() returns the host machine and can be overloaded with buisiness information.

My application should work as below;
1) User enters the login credentials.
2) Some information as the User name passed to server and if the user name is valid , the rows related to this particular user get downloaded to device.

A new user is added directly in the Users table in master database.

My questions are :
1) If I have 3000 users , should I create 3000 subscriptions with 3000 HOSTName or Login credential information to differentiate btween users?
2) If yes , other than using the wizard is there any scripts available to create large number of subscription?
3) If add subscription programatically , should I re-initialise subscription for each new user which is assigned with a diferrent host name value?

my current code looks like this

SqlCeReplication repl = new SqlCeReplication();

repl.InternetUrl = @"http://100.000.000.000/test/sqlcesa30.dll";
repl.Publisher = @"something";
repl.PublisherDatabase = @"something";
repl.PublisherSecurityMode = SecurityType.DBAuthentication;
repl.PublisherLogin = @"sa";
repl.PublisherPassword = @"something";
repl.Publication = @"somethingPublisher";
repl.Subscriber = @"something";

repl.HostName = @"newuser"; // The user name entered in the login form assigned to Hostname property.

repl.SubscriberConnectionString = @"Data Source=""Program Files esthost.sdf"";Max Database Size=128;Default Lock Escalation =100;";

try
{

repl.ReinitializeSubscription(true);
repl.Synchronize();
repl.Dispose();

}

Please advise

Merge Replication Problem On Windows Mobile 5

Sep 9, 2006

Hi,

I developed a mobile application (CF 2.0) that uses merge replication to synchronize data between SQL Server Mobile and SQL Server 2000 SP4. The application uses asynchronous synchronization (BeginSynchronize method) to initiate the replication and update the user about the progress. The application worked perfectly on PPC2003 and Windows CE .Net 4.2 platformes.

The problem started when I moved it to WM5 platform. We're using Symbol MC70 devices.

When I start the replication for the first time it synchronizes without a problem. If I perform additional synchronizations(updates) it synchronizes without a problem. If I exit the application and start it again the sync process hangs when I try to synchronize it(to deliver updates).

Any ideas?

Thank you

Merge Replication Using SSL On A Windows Mobile 5.0 Device

Feb 5, 2007



Dear ppl,

I have a windows mobile 5.0 application that syncronises with SQL Sever 2005 (Merge Replication). The replication works fine without SSL. But when using SSL it doesn't work .On the device i get an error





28037, A request to send data to the computer running IIS has failed.

I have created a a Wild Card Certificate (*.domain-name.net) using Microsoft Certificate Services (Stand Alone) and setup the replication website with replication virtual directory under it , in IIS, to use this certificate. The host header for the replication site is set to "sql.domain-name.net". I have binded the host headers to the port as well.

I can access the https://sql.domain-name.net/replication/sqlcesa30.dll from remote computer and device and it says Microsoft SQL Server Compact Edition Server Agent, that means it is setup correctly.

I have installed the certificate authority and its wild card certificate on the device Root Certificates. Now when I call repl.syncrhonise() from device .. it throws exception with error 28037, A request to send data to the computer running IIS has failed.

which i think means, it can't find the service url.

I am not sure what is the problem..something to do with Trust - SSL certificates... Is there any thing i am missing ?

Awaiting,

SQL Mobile Fails To Send Data To IIS - Merge Replication

Nov 22, 2006

This is just too simple. I must be doing something wrong. I have tried everything, redoing the SQLMobile merge publication, setting permissions, and need help ASAP.

The basic test with the http://localhost/sqlmobile/sqlcesa30.dll returns the message:

SQL Server Mobile Server Agent 3.0

I have tried the merge replication with both my local SQL Server 2005 installation and a remote development box. Both instances return the same error.

I am able create and replicate a database using the sample application:

http://msdn2.microsoft.com/en-us/library/ms171908.aspx

However, another simple applications fails to synchronize when simply using the following code block:

Dim repl As New SqlCeReplication()
repl.InternetUrl = "http://xens/sqlmobile/sqlcesa30.dll"
repl.Publisher = "xena"

repl.PublisherSecurityMode = SecurityType.NTAuthentication
repl.Publication = "SQLMobile"
repl.Subscriber = "sqlmobile"
repl.SubscriberConnectionString = _
"Data Source='" + filename + "';Password='';" _
& "Max Database Size='128';Default Lock Escalation ='100';"

repl.AddSubscription(AddOption.CreateDatabase)
repl.Synchronize()


Here is the error message:

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.

Merge Replication - SQL Server 2005, Windows Vista And MSVisual Studio 2005

Jul 11, 2007

Hello everybody!

I hope that someone could help me.

I have a problem when i start sincronyzing with the emulator of MSVS2005 to SQL2005 in Windows Vista. I have the same program in the emulator, but sincronyzing with windows XP Pro and no problem...



I configure the connection to use the IUSR.



The source code that i use:



repl.InternetUrl = @"http://laptop/SQLMobileIIS/sqlcesa30.dll";

repl.Publisher = @"laptop";

repl.PublisherDatabase = @"database";

repl.PublisherSecurityMode = SecurityType.NTAuthentication;

repl.Publication = @"Pubdatabase";

repl.Subscriber = @"SQLMobile";

repl.SubscriberConnectionString = @"Data Source='" + nomeFicheiroBD + "';Password='3409'";



The error that returns is:



"Failure to connect to SQLServer 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"



Does anybody knows what i can do?

HELP I NEED SOMEBODY TO HELP!

Thanks!

Merge Replication Issues SQL Server 2005 X64

Jul 12, 2007

Hi ppl,

I have installed SQL Server 2005 x64 Enterprise edition with Service Pack 2 on a Windows Server 2003 x64 Standard Edition with Service Pack 2.

Now I have to configure Merge Replication that will work with SQL Server Compact Edition database on Windows Mobile devices.

Distributor and the Publisher are the same server.

IIS 6.0 is installed on the windows server. I have installed the SQL Server Compact Edition Server tools on the server. However the compact edition server tools are only available for 32bit servers and I have also found out from the article http://support.microsoft.com/default.aspx/kb/912430 that you cannot replicate data from SQL Server 2005 to SQL Server Compact Edition by using the 64-bit version of IIS.
So if this is true does that mean I can not use merge replication on 64 bit server? Does that mean I have to get another 32 bit server with 32 bit IIS on it to make this work or is there another work around. Am i missing something here?

Regards
Nabeel

Merge Replication Issue SQL Server 2005

Jul 18, 2007

I have set up merge replication with 1 publisher and 1 subscriber. Distribution is handled by a 3rd server.



I can generate a snapshot at the publisher and apply it to my subscriber. But when I insert some data (approx 30,000 rows) , the Synchronization agent gives the following error when It runs:


The merge process is retrying a failed operation made to article 'xxx' - Reason: 'The Merge Agent was unable to synchronize the row due to one or more unanticipated errors in the batch of changes. When troubleshooting, increase the -OutputVerboseLevel setting, restart the agent, and check for and resolve any errors generated by the database engine. '.





I have increased the OutputVerboseLevel setting and specified a file path in the -OutputMessageFile but the File is not being populated. All the references on books online say to put the file path in the -Output parameter but when I do it says it can only hold an integer value. So I cant see the errors generated by the database engine.



Could anybody please assist with this issue?



Thanks

SQL Server 2005 Merge Replication Without A Hard Coded Password

Jan 10, 2007

Hi. I've looked all over MSDN, newsgroups and the web but I can't find the answer to a problem that I am having.

The application that I am working on used both transactional and merge replication. I want to avoid hard coding passwords into an application that kicks off the pull replication on the client machine.

The client machines are all using SQL Server 2005 Express. The other machine is running SQL Server Standard. The passwords and login details are specified in the subscription properties in the Management Studio.

A fragment of the code is posted below. The transactional sychronization works fine without having to specify any passwords - however the merge replication does not work if both of the passwords are not specified.

private void SynchButton_Click(object sender, EventArgs e) { // Set up the subscriber connection details. subscriberConnection = new ServerConnection(subscriberName); try { // Connect to the Subscriber. subscriberConnection.Connect(); // Do the transactional subscription synchronisation independantly of the // merge subscription replication. try { transPullSubscription = new TransPullSubscription(subscriptionDbName, publisherName, publicationDbName, transPublicationName, subscriberConnection); // If the pull subscription and the job exists, start the agent job. if (transPullSubscription.LoadProperties() && transPullSubscription.AgentJobId != null) { TransSynchronizationAgent transSyncAgent = transPullSubscription.SynchronizationAgent; transSyncAgent.Synchronize(); } else { } } catch (Exception ex) { } // Do the merge subscription synchronisation independantly of the // transactional subscription replication. try { // Set up the subscription details for the merge subscription (bi-directional data) mergePullSubscription = new MergePullSubscription(subscriptionDbName, publisherName, publicationDbName, mergePublicationName, subscriberConnection); // If the pull subscription and the job exists, start the agent job. if (mergePullSubscription.LoadProperties() && mergePullSubscription.AgentJobId != null) { MergeSynchronizationAgent mergeSyncAgent = mergePullSubscription.SynchronizationAgent; mergeSyncAgent.DistributorPassword = "<<password>>"; mergeSyncAgent.PublisherPassword = "<<password>>"; mergeSyncAgent.Synchronize(); }etc etc..

Any help or suggestions will be greatly appeciated. Thanks.

Invalid Column Name 'rowguid'. Error When Generating Snapshot For Merge Replication SQL Server 2005

May 15, 2007

Hi there,



I have setup merge replication which successfully synchronizes with a group of desktop users using SQL Compact Edition.



However now I have setup Article Filters and when I attempt to regenerate the snapshot I get the following error:



Invalid column name 'rowguid'.

Failed to generate merge replication stored procedures for article 'AssignedCriteria'.



When I look at publication properties at the Articles page.. All my tables have the rowguid uniqueidentifier successfully added to tables and selected as a compulsory published column, apart from the table above "AssignedCriteria".. Even when I attempt to select this column in the article properties page and press ok, when I come back it is deselected again. ( The Rowguid column is however physically added to the table)



I have scripted the publication SQL and then totally reinstalled from scratch, including the database but for some reason it doesn't like this table. I remove the article filters, but still this "rowguid" is never "selected" in article properties.



We are using Uniqueidentifiers in other columns as well for historical reasons, but this doesn't appear to be a problem in other tables..



DDL For this problematic table is as follows



CREATE TABLE [dbo].[AssignedCriteria](

[AssignedCriteria] [uniqueidentifier] NOT NULL,

[CriteriaName] [varchar](255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,

[TargetScore] [numeric](5, 0) NULL,

[HRPlan] [uniqueidentifier] NULL,

[ActualScore] [numeric](18, 0) NULL,

[Criteria] [uniqueidentifier] NULL,

[Employee] [uniqueidentifier] NULL,

[IsActive] [bit] NULL,

[addDate] [datetime] NULL,

[totalscore] [numeric](5, 0) NULL,

[isCalc] [bit] NULL,

[Weight] [decimal](18, 2) NULL,

[ProfileDetail] [uniqueidentifier] NULL,

[rowguid] [uniqueidentifier] ROWGUIDCOL NOT NULL CONSTRAINT [MSmerge_df_rowguid_7FF25DF903B6415FBFF24AC954BC88E4] DEFAULT (newsequentialid()),

CONSTRAINT [PK_AssignedCriteria] PRIMARY KEY CLUSTERED

(

[AssignedCriteria] ASC

)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]

) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]



Thanks.

Problem Using SQL Server Mobile 2005 With Windows Mobile 5 Application

Mar 23, 2006

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.

Merge Replication And SQL 2005, Help!

Aug 9, 2006

I'm working on developing a software solution using Mobile Client Software Factory. Let me start off by saying that this package is such a dream come true, and I can't thank the guys who put this together enough. The problem is, we're having some trouble getting the components setup for the Framework to work, in particular with SQL Server 2005.

We have SQL Server 2005 running on a machine, and we have our entire database setup what I believe to be correctly. Last night, we tried for hours to get the PPC Emulator running our version of the Framework to connect to the SQL Server (On another machine on the same LAN) to no avail. 

We published just one table to test with, we have the snapshot created, the web service is running, and yet it won't let us connect. The most common error we're getting from the webservice log is: Hr=80004005 ERR:OpenDB failed getting pub version 28627. 

I was just wondering if someone out there had a guide for correctly setting up SQL Server 2005 for merge replication so that remote clients can access the server through the webservice over the internet. If there is anything specifically special that needs to be done to work with the Mobile Client Software Factory, that would be great to know too. 

I'd really appreciate some help, and thanks in advance to anyone who can lend some advice.

Cheers!

Configuring Merge Replication For Side-by-side SQL Server 2000 And 2005

Feb 6, 2007

I am trying to migrate from my current system, where I do merge replication from Windows Mobile devices running SQL Server CE 2.0 to a central database running SQL Server 2000 sp3a. I want eventually to move to a system running SQL Server 2005 CE replicating to a SQL Server 2005 back-end. But the transition will need to be gradual, and I may have to support both systems for a while until I can convert all clients from the old system to the new. I also need to do thorough testing.

So ... I'm trying to set up a test environment giving me the maximum possible flexibility to do my testing. Ideally, I'd like to set up SQL Server 2000 and SQL Server 2005 on a side-by-side basis, in a manner that would potentially allow mobile devices running both SQL Server CE 2.0 and SQL Server 2005 CE to sync with either back-end server.

Can someone provide me with guidance as what is possible to set up here? I know that SQL Server 2000 and 2005 can be installed side-by-side on the same server. It also appears that you can set up SQL Server 2000 so that EITHER SQL Server CE 2.0 OR SQL Server 2005 CE can sync with SQL Server 2000 (see www.microsoft.com/sql/editions/sqlmobile/connectivity-tools.mspx), but I don't know if it's possible for BOTH SQL Server CE 2.0 AND SQL Server 2005 CE to sync to the same SQL Server 2000. As for SQL Server 2005 ... it appears to be possible to set up SQL Server 2005 so that BOTH SQL Server CE 2.0 devices AND SQL Server 2005 CE devices can sync to the same SQL Server 2005 (see web page cited above). However, I don't know if it's possible to set up a SQL Server 2005 server installation in this manner while at the same time having a side-by-side SQL Server 2000 installation supporting any level of mobile merge replication.

HELP!!!!
