Data Synchronization Through Merge Replication
Apr 1, 2008
I am designing a mobile application.I am having database in sql server 2005 and i want to synchronize this database with sql server ce database on pda.I am using merge replication method for synchronization.Please give step by step procedure for data synchronization using merge replication between sql server 2005 and sql server ce 2.0,also let me know whether sql server enterprise manager is needed or will it work without it,if needed give me the link from where to download it as it is not available in sql server 2005.
Reply soon.
Thanks in advance.

Hi..
At first I want to explain my Problem:
We have an SQL Server 2005 Database in our company. We develope an Application for customers (with VC#.NET 2005) which uses SQL 2005 Express as local database. The Application tests some devices and creates a protocoll .
As you see, the local databases must always load the actual test infos from main database (server). And the server Database must load and combine protocoll rows from different local databases (or local database must send it).
How can I solve this problem?
I could use a remote connection over tcp/ip. but it would not be reliable. I read some Info about Web Synchronization for Merge Replication. Is it possible to replicate just selected tables (one-direction (from server to client)). And is it possible replicate different client tables and combine the rows of them in server table (one direction from client to server).
I hope I could explain it. Any idea? Thanks..

IIS8 running on Windows Server 2012R2 with SQL Server 2012 SP2 installed. I have installed SQL Compact 3.5 SP2 Server Tools (64-bit) and set up the configuration. But when I in IE type URL.... I have set up the NTFS restrictions to the virtual directory. Doesn't Web Synchronization Works with IIS8?

I am trying out merge replication and using web synchronization.However, I am worried that I am missing something because the way it is set up, it strikes me as a bit too insecure.
According to the best practices and security articles on Technet, I am given to understand that:
The SQL Replication Listener (read: the application pool account that will be running the replisapi.dll) has to be the db_owner to both distribution and publisher and be on the PAL list. Windows authenication should be used. That means the merge agents wouldn't need to know the password for those logins.
The basic authenication can be used (with SSL) to authenicate into a Windows user account to then connect to the replisapi.dll.
Here's the rub - I assumed that all I needed was a basic no-rights user account to be then given the execute permission on the replisapi.dll & read permissions to kick off the process. When I browse to the replisapi.dll and authenicate using the no-rights user, I get the expected "SQL Server WebSync ISAPI" message. But when I then run the merge agent, it fails saying that login to the distribution failed for the no-rights user. If I use the application pool's account, then I am able to run merge agent successfully.
But that means I am now looking at storing the password to the application pool account on client. I might have had missed a crucial step to ensure that the logins to the distribution & publication databases are done using the application pool account, not the user authenticated via IIS basic authentication?

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'm trying out a set up as following:
SQL Server 2008 standard as the publisher
SQL Server 2012 express as the subscriber
and I tend to use web synchronization; there is no domain trust.
After following the instructions at MSDN for configuring web synchronization, I have an error that I can't get past - after creating the initial snapshot on the publisher, I try to run replmerg.exe at the subscriber and I always get this error:
"The subscription to publication 'TestReplication' has expired or does not exist."
If I refresh the publisher's "Local Publications" and look within the "TestReplication", it does show that the subscriber is a known subscriber. Likewise, if I refresh subscriber's "Local Subscription", it has an entry for TestReplication publication.
I already verified that the user used by Replisapi.dll has the read permission to the snapshot folder, is a member of PAL, is db_owner of the publishing database and distribution database. I am using self-signed certificate for this test and I have already installed the certificate at the subscriber machine so that HTTPS is trusted. I can run diagnosis from subscriber so I know subscriber can reach and logs are being left at the publisher's IIS.

Hi I want to Set up Such Merge Replication, Which can can Synchronize With out Network, Means Syncronization using CD.
Also When the Network connectivity will be available then it should do synchronization
I wants to transfer some file using CD only those changes to database which hasn't been synchronized, thats why Backup will not work.
Pls Help me, or tell me wether it is possible or not.
Tell me some work around, or ask me details,
You got to help me out, Otherwise I will loss trust in MSDN Forums.
Thanks in advance

I'm updating some tables in a subscriber database with a stored procedure. After the tables get updated I'd like to sync them with the other subscriber dbs and the publisher db in that same stored procedure.I can do it manually in SSMS with the View Synchronization method. Are my only alternatives a batch job or C#?

Hi!
I've the following replication topology:
SrvA (Publisher/Distributor) -> (Transactional Publication/Push Synchronization) -> SrvB (Subscriber, Publisher/Distributor) -> (Merge Publication/Pull Synchronization via HTTPS for remote clients) -> Client (Anonymous Subscriber)
To test synchronization with this tier I do the following:
1. Update data on SrvA
2. Push changes to SrvB (there are transactions that replicated)
3. Run RMO Merge Agent (.NET application) on Client and get messsage "No data needed to be merged", although there were changes made on publisher SrvA and SrvB
I saw the thread where similar problem have been discussed (http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=664153&SiteID=17). The sugestion there was to create subscription using wizard rather then T-SQL script. But all my clients are remote and have only HTTPS connection to the IIS over 443. And in the MSDN there was the script that I used to create pull subscription for web synchronization.
Guys, HELP! I almost gave up - do not see the reason for the case in the documentation, settings and code.
Thank you.
Alexander.

Hello,
We have an environment with 7 servers that are running replication with one another and I'm wondering if there are any tools or experiences that any of you might have that may assist in the auditing of these servers. The data should be in synch accross the boards for all tables, but sometimes problems can arise such as replication not being set up properly, stored procedure's being out of synch, or data gliches etc.
In dealing with these issues we have an in-house written program which analises each table on each server and takes a snapshot and does column by column compare. We also have another program that will synch the data up (basically a delete/insert statement on the publisher). This process can take up to 3 weeks for our quarterly update of every table. I'm wondering if anybody has used any tools such as in SSIS or a third party tool and has done or is doing something similar to what we are doing now. If so, are there any tips you wouldn't mind sharing on how our process might be sped up?
Thanks,
Phil

thanks 4 ur rpl..well i have a simple doubt if u can guide me it will b gr8 help..well i am developing an application of location based services, in which i am going to store my data on SQLserver 2005 and will fetch the data from it when the user logs in to the user's PDA device so that a user can work offline on the data when there is no connection and when he gets the connection he can synchronize the data with SQLserver 2005. so now i m confuse whether i should use the merge replication or ado.net synchronization framework or RDA?what is the difference between merge replication and synchronization and which is better?

Dear ppl,
I have a question for you. One of our client has asked us how is the data secured over the air during Replication?
I have read that Merge Replication uses TLS (Transport Layer Security) protocol to secure the data over the air. But I was wondering if it is all done automatically ? Or do we need to install certificates like for SSL.
We have a Windows Mobile 5.0 application using SQL Mobile that runs over 50 devices and they all synchronise with a single Publisher SQL Server 2005 using GPRS connection. We haven't got any SSL certificates installed on the server.
Now how can i make use of TLS in my application to secure my data over the air (using TLS)?
Regards

We had merge replication setup between 2 tables, Table A and Table B using SQL 2000. This was working 100%. The users asked to disable updated/deletes to both these tables if data existed on 2 other tables. Table AA and Table BB. We implemented it as follows:
1) Created Insert/Update/Delete triggers for Table A & B. It basically check for Table A is there a record in Table AA, if it exists, raise an error and don€™t commit.
2) Removed all foreign constraints from Table AA and BB
3) Added Table AA and BB to the current replication.
Then all hell broke loose, we got conflicts all other the place saying that Table AA cannot be updated because records does not exist in Table X. To our surprise we found triggers generated by Erwin in 1998 €“ that check for €śforeign contsraints€? and removed them immediately.
We continued to get conflicts but could see from the error messages it was generated by the triggers in point 1. We added the NOT FOR REPLICATION clause and everything has been running smoothly or so we thought€¦..
After 2 months we got a call that data is missing. It€™s random data and the only explanation I have is that replication caused that. My biggest reason for saying this is tracking the application audit trail I€™ve found that all the data missing was added during the period we had all the conflicts.
I need a solid explanation for this and can anyone confirm that this is possible?

Hi gang,
We have a database that's using merge replication between two servers, and we need to insert a lot (about 1GB) of data into it.
The servers, however, are separated by a 192k WAN connection, so it's impractical to rely on the merge replication to send the data across to the subscriber.
Is there a way to insert the data at both ends? I can get the data out there on a DVD or a laptop easily enough. Can I load the data into both copies of the database and tell the merge agent that it's not to be replicated?
Thanks,
Matt

Hello,
When I reinitialized a subscription from SQL2005 db (publisher) to a SQL 2000 DB (Subscriber) and had the Upload changes before reinitialization turned on, the data from the SQL 2000 db didn't get uploaded. This resulted in a loss of 2 days worth of data.
Does anyone have any idea if there's anywhere that data is kept. (unfortunately a series of errors caused our backups to not be running on the 2000 db either).
Thank You

I'm having an error with merge replication my suscriber are downloading old data, all this start happen after I install SP4.
let explaint this with more details ,
if a made an update to a row in a table from the publisher , the agent history show that 1 change have downloaded to the suscriber, a put an audit in the suscriber and yes one update was downloaded but the row still the same, look like the suscriber downloaded old data instead of the curent change that i made.
If i delete the row, the rows gets delete at the suscriber, if a insert the row the row get insterted ok.
The problem only happen with rows inserted at the suscriber, that later on get update at the publisher. My suscriber has MSDE 2000 SP3 an my Server has SQL Enterprice 2000 SP4.
Any help would be apreciate. thxs.

Hi,
We have configured one-way merge replication in our topology. That is data flows from Subscriber to Publisher only. We have a publisher and a subscriber. There are 3 publications in this category and each publication has a subscription. We use SQL Server 2005 SP1 in both the servers. The retention period is the 14 days (default). After this period, I get the following error in the subscription in Replication Monitor. The Error message is
Error messages:
The Merge Agent failed after detecting that retention-based metadata cleanup has deleted metadata at the Publisher for changes not yet sent to the Subscriber. You must reinitialize the subscription (without upload). (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147199402)
I read the post http://forums.microsoft.com/MSDN/ShowPost.aspxPostID=372790&SiteID=1
which said that this error might be solved in the SP2. We have not yet applied SP2, but even after applying SP2, will this error be solved for One Way Merge Replication since the data from publisher will not go to the subscriber always in this type of topology??.
Kindly get back to us regarding this as soon as possible. Thanks in advance.

Swapna.B.

Hi all.
I 'm trying to set up merge replication between two servers that have the same schema databases. The two database have the majority of there data the same but as well as data inserted at a later time independently on the two servers. (The two servers were connected in a merge replication scheme that failed at some later time and replication was paused, but users continout to insert data indepentedly at the two servers.)
I need to get them up and running.
I cleaned replication at both servers, I recreated the publication at the puplisher distributor and all is fine.
When I create a push subscription to the subscriper I get the error invalid column name 'rowguidcol' .
I so far managed to have merge replication running on two identical databases (schema and data).
Just some thoughts. After some reading I found that it might be related to identities and identity range or indexes. I set the identity seed and increment at 2, 2 at publisher and at 1,2 at subscriper. (On the same tables at puplisher and subscriber.) Is that ok? is that the way to do it?
Digging a bit more Using the SQL Profiler I can locate the error to happen when sp_MSaddmergetriggers executes.
Thanks allot for any help

I have the merge replication (Push)Â for SQL Server 2008.The right-click option for Start and Stop Synchronizing in subscriptions has been disabled. How can I stop the merge replication and start again ?
This error happened 1 week after I created the merge replication. The merge data cannot sync to subscriber and only solution I can use is drop and re-create the merge replication again but error would be re-occur a week later. The merge replication work fine before and start from middle on May 2015, but it keep happen right now.

Hi all,

2nd for displaying data after inserting the value into table
just see the screeenshot which i have taken
actually the problem is, we are not getting any type of errors even though I have try/catch blocks.
I have colored that particular statement in RED color, where it is getting stuck, while executing, if we sit 40-45 minutes then also the execution pointer is not going on next step.

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:

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()

Hi all,
I know that adding a column using ALTER TABLE to add a column automatically allows SQLSERVER 2005 to replicate the schema changes to the subscribers, however, I would like to add a new column to an existing article that is being used for merge replication, however, I don't want this column to be replicated. Re-initialising the subscriptions is not a option. Help would be appreciated.
I am using SQLSERVER 2005 (SP1).

I am working on bringing our disaster recovery site to be a live site. Currently we replicate to one of out servers (server B) with merge replication (from server A). Server A also does one way transactional replication form some table to several other servers including servers at the DR site.
This setup is not going to be fast enough for what we need so I am wondering if a table is receiving merge replication will the merge updates also replicate down the transaction path??
Example...
Server B update a row and merges to Server A. With this update them replicate (via transactional) to Server C??
thanks...
