Hello,
If I want to access or modify my local subscription data(not the configuration) how can I do that(from sql server 2005 or from asp.net)? Also can i update directly to the local subscriptions data or do I need another layer which will update from a table for example??
Thank you
Salah
I'm trying to modify subscriptions from within Management Studio. I connect to the report server, navigate to the report subscriptions and when I right-click, the properties selection is greyed out. I'm guessing this is because the original creator has ownership or something, but it would be really nice to be able to modify all subscriptions from Management Studio. Has anyone else tried this? Maybe i'm missing a security setting or something. I'm connected using windows authentication and i'm in the System Administrator role. Thanks!

I have an existing VB6 application which uses an Access 2003 backend datafile, however, I would now like to modify this to use an SQL 2005 datafile, but I don't know how to go about this or the implications when the application is installed on another machine.
The code I use for accessing the Access 2003 file is below, I want to convert this code to access an SQL 2005 datafile instead, can anyone give me some pointers on the best way to go about this, or code sample.
Dim rst As ADODB.Recordset
Dim dbs As ADODB.Connection
Set rst = New ADODB.Recordset
Set dbs = New ADODB.Connection
dbs.Open "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & _

Hey there!
In a nutshell, I want to do a merge replication with a SQL Server and
several Access databases. I haven't been able to find anything in the
documentation or 3rd party books.
Is this possible?
Thanks!

Hi everyone,
I am trying to add a new subscription to the local subscriptions of a SQL Server 2005. As soon as I click on SERVER_NAME -> Replication -> Local Replications -> New Subscription, I get the following error message:

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)?

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.
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 €œforeign 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?
does anyone has idea why the server hang when i try to drop merge subscriptions?
any suggestion would be appreciate.
thanks.
How can I list all of the Subscriptions in a CE Database that was created with the .Net System.Data.SqlServerCe.SqlCeReplication.AddSubscription method?
After I create the CE database in an sdf file, I can connect to it with SQL Servr Mgmt Studio, then see the list of Subscriptions in the Object TreeView, under "Replication"
But I can't find that Subscription list in any properties or methods of System.Data.SqlServerCe.SqlCeReplication or System.Data.SqlServerCe.SqlCeConnection
Should I be looking in RMO features like Microsoft.SqlServer.Replication??
We want to confirm that a local CE database was last synced from the expected SQL Server database by checking the Publisher property of each subscription in the CE database.
Thanks
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
Bob
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.

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.
I have multiple web databases for storefront orders as linked servers on SQL Server 2008 R2. I need to organize the data for these orders into a structure that can be imported into my ERP application db frequently either on demand or periodically during the day. We are essentially trying to make the manual order entry process automated. My thought was to get the data into views that resemble the schema of the order table in my application db and then schedule a stored procedure with sql jobs or a load routine from within the ERP application that would insert data from the view into the order table.

Hi everybody, I'm quite new to SQL 2005 and I€™m trying to understand some key concepts regarding replicas. I need to develop an application with characteristics similar to the Sales Order Sample for Merge Replication, on the client side it should run with the express version of sql server and also the synchronization should only work via web. I try to run the sample but I got an exception in the CreateSubscription method on invoking publisherConn.Connect();
TITLE: Microsoft.SqlServer.ConnectionInfo

Failed to connect to server XXX.

Login failed for user ''. The user is not associated with a trusted SQL Server connection. (Microsoft SQL Server, Error: 18452)
I can€™t understand how this connection could work if it isn€™t aware of the fact that it should use https to connect with the server.
Can someone point me in the right direction?

I have been trying to set up replication with updateable subscriptions. I first followed the tutorial on MSDN and set up basic transactional replication. This all worked fine. I then tried, using that tutorial as a basis, to set up replication with updatable subscriptions.
On the Agent Security page you are asked for a Snapshot Agent, a Log Reader Agent and a Queue Reader Agent. I assigned these to the following accounts, which I created and added as logins, PUBLISHERSERVER
epl_snapshot, PUBLISHERSERVER
epl_logreader and PUBLISHERSERVER
epl_queuereader.
I then tried to set up a subscriber on SUBSCRIBERSERVER. Under the publication I add new subscriber, select the publisher, add SUBSCRIBERSERVER as the new SQL server Subscriber. In the Distribution Agent Security page of the wizard it asks for process account, which will be run when synchronizing the subscription. I entered PUBLISHERSERVER
epl_distribution here and selected the other two default options of connecting to the distributor and subscriber by impersonating the process account. I then took the default options for the next few screens and finally get to:
Login for updateable subscriptions. This offers the option of a login or using a linked server. I have tried various logins here, initially trying the €˜sa€™ login and password. This produced the error: The user is not associated with a trusted SQL Server connection. The servers are set up for mixed mode operation. I then tried PUBLISHERSERVER
epl_distribution and subsequently every other account I had created on PUBLISHERSERVER. All of these failed. I tried linking the servers, but this also failed. How exactly do you set up subscriber with the ability to login to the publisher? I have spent days trying to set this up, and am as you can gather new to this technology, any help would be greatly appreciated.
I have recently deployed a sql replication system into a production environment and I€™m experiencing a few problems.
I have a server holding consolidated data (4 processor/2GB ram) and fifteen subscribers, each being a 400Mhz Celeron with 256MB ram.
Transactional replication is used to pull base data from the main server to the subscribers. This data does not change very often at the publisher, but the subscribers need an immediate update, so continuous transactional replication is configured at the subscribers. This data will never be changed at the subscriber.
The server has another three tables used for historical data. Each subscriber has been configured for merge replication on these three articles. An initial snapshot is run to setup each subscriber. Each subscriber writes up to 10 records per minute into these local tables and continuous merge replication replicates these 10 records from the subscriber to the publisher. As all subscribers are doing the same, part of the merge operation will potentially bring down 140 records to each subscriber (10 records from each subscriber merged to the publisher and back to each subscriber).
Anyway on to the problem€¦
Each subscriber system has a Microsoft.Net application writing these 10 records per minute to the local database. Refreshing a graph within the application occurs once every minute. Refreshing, queries the three local tables used for the merge replication. This application shows an error (randomly) with a sql timeout message trying to get a connection to the local database.
Has anybody got any ideas why this will occur?
If I have one table in one publication in transactional replication
replication between primary and replicate is broken because subscription is marked as inactive.
If there are 3 rows on replicate and 5 rows on primary , out of which 2 are added after replication is broken
If I do
Reinitialize subscriptions
start the snapshot agent
start the distribution agent
Does this mean that it will only transfer the new 2 rows to replicate sites ? or will it drop everything from replicate site and apply all rows from primary site on to replicate.
Any help is appreciated
Hello,
I have the following situation. I have a single publication on my publisher Server. This publication is created using SQL Server Manager. Snapshot is created completly. Now I want several Pull subscriptions from several machines to work with this publication (One subscription per machine). I'm creating these subscription using RMO. I'm synchronizing data using RMO again. My code workflow is:
Syncronize -> success -> do nothing
-> fail -> Check if everything with Publisher and Publication is ok -> Generate Snapshot -> Create Subsscription -> Sync again. (I tried to eliminate Generate Snapshot step but couldn't because I receive error that I must rerun Snapshot Generation.)
When I tested my code per single machine it's working. Next test I tried was to run my program on 2 machines simultaneously.
The result is:
---> System.Data.SqlClient.SqlException: Another snapshot agent for the subscription(s) is running or the server is working on a previous request by the same agent.
or:
---> System.Data.SqlClient.SqlException: Unable to acquire the replication merge administrative application lock for database 'XXX'. This could be due an active snapshot running while the schema change (DDL) or the administrative proc change was attempted.
Replication merge admin stored procedure 'sp_changemergepublication' failed for publication 'YYY'. This could be due an active snapshot running while the admin proc was called.
The problem is obvious but because I'm new to the replication I'm not sure if I did general mistake in what I want to achieve. Any advices how can I fix my problem will be highly appreciated.
