Merge Replication Sql Server 2000 With SQLCE 2.0
Apr 6, 2004
I do a merge replication between Sql server 2000 and SQLCE 2.0
On my SQL2000 I have 4 tables i want to merge (specific columns only ) in 1 table for Merge with my SQLCe ( the table will be use for read only)
Question 1:
What is the best pratice for keep the information update?
Run store procedure before the synch for re-populate the table?:confused: or Make Trigger INSERT, UPDATE, DELETE in the all 4 table?:confused: or a mixte?:confused:
Question 2:
Does someone know about some web site talk about this type of trick?
Thanks

I am using SQL Server 2000 SP4 running on a MS Server 2003 with SP2. I am preforming Merge Replication on a continouas basis and the Merge Agent keeps stopping with the error 203 The process could not enumerate changes at the 'Publisher'. There is no additional information available with this error. Does anyone have any sugestions as to why this is happening. I can manually re-start the agent but it will fail again for particular reason.

Hi, I posted about this before, and set out on my own to get this working, and haven't been able to. I'm trying to get merge replication working with my SQL server 2000, and after 2 weeks I still have nothing. I've gone through multiple 'walkthroughs' which all brought me to the same point. I'm getting down to crunch time, and I'm either going to use this or implement my own merge algorigthm (I'd much rather use this). So here's where I've gotten to:

Hi,
I am trying to replicate a production database server,on sql server 2000 at a particular geographic location to a new failover database server on sql server 2000 in a different geographic location via internet. The intention here is to use the failover database during times when the production server is down or busy and the synchronization needs to be sceduled for every 10 min.
It will be of huge help if any expert could give the detailed process involved and any precautions that need to be taken. I also need to keep inmind to use the ever/odd sequence number generator during the replication implementation.
Also, Whether to use row-level or column-level tracking?
thanks

I have a problem with sql server merge replication in sql server 2000.
If my db owner €œdbo€? and replication setup under €œsa€? account it works with out any problem. But when I use another db owner it can not work properly.
For an example I have customer table ([dbo]. [Customer]) When I setup merge replication under sa account it€™s work properly.
Again I was setup merge replication using another db owner ([INV]. [Customer]) It doesn€™t work.

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!!!!

hi, i was trying to use a merge replication between 3 SQL 2000 Servers.
The problem is that the replication process generate to many data conflicts and i dont know why, because in the others 2 servers was nobody.
only 1 users have active users the others doesnt have anyone yet, if no updates and no inserts were made in the other 2 servers, why the conflicts?
the server have Win 2000 Server.

I have a merge replication publication that has been running for
months. This week the Snapshot started failing, reporting that an
article was not included in the publication. I checked and found
3 articles that mysteriously no longer show up as being in the
publication. When I attempt to add them it reports that it can't
add them because there is already an article by that name in the
publication. Apparently some table has lost its rows for these
articles while another table(s) still has its rows.
Has anyone had this problem? Is there a solution short of
dropping the publication and starting over - a solution that would
literally take weeks for us?
Thanks for any help.

we had setup merge replication on 2 db servers. For some reason, the subscription started failing a month back with the error " invalid object sysmergexxxx on the subscriber. I did a reinitialize and now all the changes on the subscriber which werent synced got deleted. I have tried all 3 log recovery tools with no luck. Is there any hope of recovering data. the last backup on the subscriber was a month ago.

Hi All,
My question is regarding syncronization between two databases in MS SQL Server. If we wanted to do MERGE REPLICATION then we can set up pulishers and subscribers using the PS/SQL script (stored procedures) without having to use Enterprise Manager gui tools. I see that after you set all the publishers, distributors and subscribers and you want to start syncronization explicitly the only way you could do is go to Enterprise Manager and find the Publishing/Subscribing Items and right click on them and choost "Start Syncronization" (Sorry I have omitted the nitty-gritty details about how to find those Publishing/Subscribing items in Enterprise Manager).
I am wondering whether we could trigger the start of syncronization using any system stored procedures or without using Enterprise Manager.
Please let me know if you have any idea about it.
I will highly appreciate your response.
Thanks,
Niben Singh

Hi everyone,
I'm currently trying to setup a SQL 2k (SP3, build 922) merge replication publisher and a push subscription to a SQL 2005 (RTM release, no hotfixes) subscriber. The distribution database resides on a separate SQL 2k server (SP3, build 1007). I get the error below leading me to believe merge replication is not compatible between versions.
Replication-agentclassname: agent Agent_Name failed. Procedure or function sp_MSupdatesysmergearticles has too many arguments specified..
I say this b/c I've tried SQL 2005 32-bit and x64 subscribers and both give the same error. Anyone have any ideas if this is by design or just a bug that will be fixed later? Thanks.

We have developed a mobile system that uses merge replication for SQL Mobile to SQL 2005. Previously we have developed mutliple mobile systems using merge replication for SQL Ce to SQL 2000.
Based on the knowledge we had gathered over about 4 years, we applied the synchronisation parameters for the SQL 2005 solution as we would for the SQL 2000 solution.
We have found there are some differences. Not too surprising I suppose, only some of these have us a little baffled.
For instance, there was a little flag called keep_partition_changes in SQL 2000 that is supposedly superceded by the use_partition_groups flag. However, if you don't set up your filtering to conform to the standards required by the use_pre_computed_partitions flag if you want it set to true, then the use_partition_groups flag gets set to false - also the @partition_options falg gets set back to 0 (static or non-unique data) when we want it at 3 (Single Parition, One subscriber).
To top it all off, when you get the use_partition_groups flag working, there are restrictions on which columns you can update on the device. WTF? This seems ludicrous, to be unable to update data at the subscriber - particularly information that allows you to effectively "delete" data from your subscription.
Examples of the current behaviour are as follows,
On initialize for a subscriber, the subscriber will receive their own data as inserts, plus exact multiples of that data as updates. Say there are 100 rows in TableA, the subscriber gets 100 inserts, plus 6000 updates. TableB has 20 rows, the subscriber gets 20 inserts, 1200 updates.
Further to this, performance goes out the window when synchronising changes. Typically the data flow will be between 5 and 200 changes in both directions for a synchronisation. We are seeing sync times in the replication monitor of over 20 seconds per user. Surely the calculations do not take that long. The tables in the database are not very large.
This behaviour gets significantly worse as we load the system. The application has an auto sync function which is timed to operate evry 10 minutes. However, now that there is in excess of 50 or so users on the system, those synchronisation times blow out to multiple minutes and the server starts to thrash. We have looked at indexing and maintenance but to no avail.
Everything still points to the merge replication setup.
So, it seems obvious to me that we are mising some key information about how to set up merge replication in SQL 2005. We woudl be very gratefull if someone could point out the errors of our ways.
Sorry for the convoluted post. Hope someone can help us.
Cheers
Steve

Publisher is 2005 x64, subscribers SS2000 (SP3) and SS2005 x64. Pull agents, no filters on subscriptions. We are seeing many seemingly random conflicts on between SS2000 subscriber and publisher. It happens on several different tables.
One table is never editted, only inserts happening everywhere and deletes happening on the SS2000 subscriber. Deletes will sometimes generate conflict. Reason is '"he row was deleted at 'CTS11.CTS' but could not be deleted at 'cts4a.cts'. Unable to synchronize the row because the row was updated by a different process outside of replication." CTS11 is SS2000 subscriber, CTS4A is publisher.
Probably unrelated bug but when looking at conflicts on this same table in SS2005 conflict viewer, get error "ID is neither a DataColumn nor a DataRelation for table summary (System.dATA)" and then "Column ID does not belong to table summary (System.Data)". ID column is rowguid, only unusual thing about table is that it has varchar(8000) field plus some other fields.
Other tables generate conflicts with this reason "The row was updated at 'CTS11.CTS' but could not be updated at 'cts4a.cts'. The merge process was unable to synchronize the row." I enabled verbose logging in the merge agent but the log file didn't contain any further explanation.
This same topology and schema worked fine when all publishers and subscribers were SS2000.
Any insight into how to fix this would be appreciated.

Hello!
We have a module in our business-application, that automatically installs merge replication of the business-application's database, both at publisher and subscribers. It's intended for Sql-2000. Now we need it to be applicable also for Sql-2005, so the module requires some changes, because, as we noticed, sql-2005's replication technology differs from Sql-2000's one.
A few questions to experts, familiar with Merge Replication in SQL-2005:
1. Is it possible to create hybrid replication, with publisher running at SQL-2000 (MSDE) and subscribers running at SQL-2005 Express? Merge publication is not supported in SQL 2005 Express, but some users may require option to use the application at free-of-charge database platform.
2. How deep are changes in merge replication implementation at system level? Is it just modified a bit since SQL-2000, or changed entirely? This knowledge is needed, because the module uses some low-level features (executing system sp's, querying replication-specified tables, etc.). For example, when we tried to create subscription of existing publication in SQL 2005 using the module as is, we found out that sp_addmergepullsubscription_agent doesn't use @encrypted_password parameter anymore, and subscription creation process failed.
3. If anybody has experience using merge replication creation/deletion/detection scripts, generated by SQL 2000, in SQL 2005! Please, tell - what more problems may happen?
Thanks!

Problem encountered:
Error Code: -2147467259
Message: A call to SQL Server Reconciler failed. [,,,,,]
Minor Err. 29006
Source: Microsoft SQL Server 2000 Windows CE Edition
Any idea what could be the possible problem?
I have been trying to search thru the internet for a resolution but most of the guides are very brief about the configuration of the merge replication in mssql2000 server.
e.g. http://msdn.microsoft.com/msdnmag/issues/03/09/DataPoints/default.aspx
This link above its recommended by Microsoft, but still doesn't really helps.
Does anybody have a step-by-step guide on configuring the merge replication in mssql? With diagrams preferred.
-OR-
Is there anything wrong with these codes:
oRpl.Publisher = "HANBIN"; // HANBIN is my database server name
oRpl.PublisherLogin = "LHP";
oRpl.PublisherPassword = "<password>";
oRpl.InternetUrl = "http://hanbin/ssce/sscesa20.dll";
oRpl.InternetLogin = "IUSR_HANBIN";
oRpl.InternetPassword = ""; // do i need to put sth here?
oRpl.Subscriber = "CESubscriberTest"; // Any names will do?
oRpl.Publication = "testdbpub";
oRpl.PublisherDatabase = "testdb";
oRpl.Distributor = "HANBIN";
oRpl.DistributorLogin = "sa";
oRpl.DistributorPassword = "<password>";
Any help from any genious will greatly be appreciated.

I have some problem about Merge Replication.i'm trying to merge Database A to Database B in local Server. So Database i want publisher contain this:
Because only Data in Table change therefore so i choosed it 100% Snapshot was generated after that ( Problem not a valid window user i already figured out )After that. I created Local Subscription in same Server ( Pull subscriptions and Subscription type: Client ),now problem is throw out."The schema script 'vwBuyADT_513.sch' could not be propagated to the subscriber."
I tried research so many time in Google but any information i found isn't useful for this problem.This problem still can ignore,Synchronization still running. But after 4-5 Hours running..This messages throw out: "The Publisher failed to allocate a new set of identity ranges for the subscription. This can occur when a Publisher or a republishing Subscriber has run out of identity ranges to allocate to its own Subscribers or when an identity column data type does not support an additional identity range allocation"
My question is:
Is there anyway solve 2 probem? :
1. "The schema script 'vwBuyADT_513.sch' could not be propagated to the subscriber."
2. "The Publisher failed to allocate a new set of identity ranges for the subscription. This can occur when a Publisher or a republishing Subscriber has run out of identity ranges to allocate to its own Subscribers or when an identity column data type does not support an additional identity range allocation"

Hello,
I am having problems with my sql merge replication. Whenever a user syncs up to my main database, most of their records are deleted instead of being merged.
Or the records on the main database are inserted and it replaces the whole table with the records on the remote laptops. Is there a way to prevent this from happening? Someone please help me.

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

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......

I am running SQL Server 2000 and SQL Server CE on the handheld device. I have created the publication on the SQL Server.
I can subscribe to the publication successfully on the handheld and it creates the .sdf file just fine.
When I then attempt to synchronize, the process will run for a long time and eventually error out. (The database has a couple large data tables that are used for value lookups)
The error says the connection was broken.
Any suggestions on correcting this?
I am thinking of breaking the replication database into 2. One with the large lookup files and one with the updated tables. I still need to get the large database with the lookup tables onto the handheld though.
Any thoughts, advice or similar experience handling a situation as this would be appreciated.
thanks,
Dan

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?

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

At first we received error like
"The merge process could not retrieve identity range resource for table..."
then after solving this error we again started syncing of servers manually then we got some other error like
"the process could not enumerate changes to the subscriber".
We tried our best to solve this problem but some error appears each time like
"The process could not deliver the snapshot to the Subscriber."
"The schema script 'sync -t"Design" -o"dbo" -d"\ECOSYSTEMD$FTPMSSQLEcoSystemftpECOSYSTEM_MLEcosystem_MLEcosystem20060619204802Design_1337.bcp" -hORDER( [intDesignId] ASC)' could not be propagated to the subscriber"
again identity erroe emerges and agin we do the same process.
How to solve these problem?

We have a central office with a SQL2005SP4 server (yeah, I know... old as heck) that's the main database and it has multiple subscribers in regional offices. Well... one of the regional offices server is failing, and it needs to be replace.
The original server is an ancient Win2003 86x
The Server team will build a new Win2008r2 64x, and use the same name and IP address
And I'm tasked with the SQL part.
I'll be installing the same version/patch of SQL, but 64x instead, and migrate all databases, including the system databases.
How do I handle replication? Do I need to reintialize from scratch? or can I just use the backup as a starting point?
