Merge Replication Locked
Jul 11, 2007
Hi All
New to sql server .
Have setup several pilot installations using merge replication between sql server mobile and sql server 2005. All has been perfect for over a week in all locations. last night one of the ocations stopped updating. Upon further investigation all devices kept throwing errors: "The database is currently synchronizing with the server". So I left for a further 2 hours with no change. The replication process usually takes abot 1 second and never take more than 3 or 4 seconds. There was no change to the data at all in this case either. I fixed the issue by restarting the whole server.
It would seem that there was some kind of lock on the database. Being new to sql server my question is:
Is there a way to properly diagnose the cause (I looked in the system event log and found nothing).
Is there a way to get notified if this occures again.
We are plannng hundreds of similar installations and cannot constantly monitor all of them in the hope of finding this issue again.
Regards
Nick

skip locked records in a MERGE statement and output the list of skipped records.
Through the documentation, internet posts and testing, I believe it is NOT possible. MERGE acts like a single atomic DML statement, and therefore cannot avoid locked records.
I can use the READPAST hint, which will skip the row-locked records. However, it could actually insert duplicate keys in certain cases (as it is ignoring records, i would guess), which would not be acceptable.

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...

I have just installed replication on our production server to Merge Replicate with a Laptop server that will travel from time to time. I have now noticed that we cannot add or change any fields or attributes on the tables which are being replicated (which are all tables in the DB). This is a problem because we are changing and adding columns all of the time. Is there a way around this issue like shutting down the replication service or something? I have been unsuccessful in finding a way around this other than removing replication while we make changes.
Thank you in advance for any help!

Hi all,
I have a merge replication going between 4 servers. The problem is when ever I do some BCP transfer to one of the tables in one of the servers. It puts the data in that table. But that Data does not get replicated to any other server like it should.
Please Advice on what to do. Is there any option I am forgetting to set or something.
Thank you for all your time in advance.

Hi All,
I have posted this earlier and I am re-posting it simplifying what I had said.
The scenario is:
I have two sql server database instances with the same database schema and all. However, both of them have different data. I have not set them for replication at all. Now, I want to do merge replication between them such that the data between them could be syncronized.
When I do pull merge subscription I have two choices -
1.Bringing schema and data to subscriber from publisher
2.Not bringing the schema and data from publisher to subscriber.
Obviously, I chose the second choice. But upon syncronizing I dont see any data from publisher coming to subscriber and vice-versa. If I add new data to publisher and do syncronization, I can see ONLY the new data created after the replication setup in subscriber. If I add new data to subscriber and do syncronization then the new data is removed from subscriber and not propagated to publisher.
Is there any way I can make this work??

Hi,
I have just set up Merge replication, I have two servers, server A and server B, the merge replication worked successfully but I don't quite sure which databases should or should not replicated? If not, what other methods should I use?
I would really appreciated any comments or advice out there!

Hi everyone
SQL Server BOL says merge replication can be done in only one direction. But my understanding is Merge replication happens in both ways between publisher and subscriber.
How can i allow data movement from only wince sql ce subscribers and not from publisher running sql 2000 and win 2k.
Please reply immediately bcoz i require a solution which has to be implemented very soon.
Thanks in advance

I am in a process of learning Replication in MSDE, especially Merge Replication
Server runs on MS-XP Professional
--------------------------------------
I have a sample Access project 'ReplTest' which has only table with only 2 columns.
DatabaseName:ReplTestDB
Table Name :TestTable
MSDE Instance Name:SVRMYINSTANCE
Now I would like to know how I can configure this database for merge replication
using SQL-DMO
Laptop runs on MS-XP Professional
--------------------------------------
I have another access project which is running on computer 2 and connected to the
ReplicaTest database.
MSDE Instance Name:LPTMYINSTANCE
My task is, when I am disconnected from server I would like to have a local copy of
the database to work with and then, when reconnected, need synchronization with the
server database and continue working from server database.
How to write this replication process from scratch using SQL-DMO objects in both Server computer
and Laptop computer.
I dont have enterprise manager in both computers since they use only MSDE
Can anyone help me?
Thanks in advance

Hi,
I have a problem when doing merge replication. I need to have a identity column on both the publisher and subscriber, eg id. When the publisher is down, my app will now reference to the subscriber and insert into the subscriber. However when the publisher is up, the app will reference to publisher and start to insert into the publisher. This will cause conflict in the id. Also, i need the id to be in running order, therefore i cant use range for publisher and subscriber. Anyone have idea how to solve this problem?

Hello,
I am having a problem getting my merge replication to work out. I am wanting to make it where the merge happens on demand. I have tried to run replmerg through cmd prompt and I get the error 'The subscription to publication [namehere] has expired or does not exist.' I have had no problems running the merge agent within Enterprise Manager. I have thought of running windows sync manager but I do not want my people to have to type a password in everytime they need to sync. I am running the whole replication process through FTP. I am in desperate need of help. Anything would be great!
Thanks

I have merge replication setup between 2 servers and the subscriber had been offline for about 24 hours due to a network outage. What would be the best and easiest way to resynch the data. Would my best bet be a reinitialization or should I start a new snapshop and reapply. Also can I start a snapshot while users are using the publishing database?
Thanks,
Mike

Hi I am looking at SQL Replication and merge replication seems like the solution as I have 30 Remote offices who will all add data to their data bases and sync that data back to a central office. The central office will then use the "whole" data for reporting etc.
I am trying to figure out if I need static or dynamic filtering. I only want to filter horizontally on values found in a column called 'office' This value will be an integer that represents the different remote offices. But after reading through documentation I am still unclear as to whether I can do this with static filters.
Any help/advice appreciated.
Regards and TIA

I have a sql 2005 application where sql express clients perform merge replication. Work great except where I have a poor internet connection that has latency in the 500-1000ms range. I have been told by someone looking at ethereal capture that i have an inordinate amount of TCP ACK's, DUP's and retransmission attempts. The question is, is there a timout parameter that could be increased to wait a bit longer?

I have a replication question. I have a rather large transaction database, that until now received only transactions from a local application. At the moment we're deploying the same application at pretty much the other side of the world.
There is a VPN connection between both locations, but the application will run locally and use the local database for latency reasons. Now I want to maintain a central database (for reporting purposes). What is supposed to happen is the following. Both databases will receive new transactions and updates to existing ones, each by its own local application, but I want the transactions of the remote database (and updates to existing transactions) to be merged into the main database (but not other way around!). There will be no conflicts between these transactions, since each transaction ID will be prefixed with a location ID.
Initially I thought I could use SQL Server's merge replication, but this requires both databases to contain the same contents. This is not what I want, since the main database is far bigger than the remote database is supposed to become. Also I do not need the transactions from the main database to be in the remote database.
As an alternative I was thinking along the following line: replicate (using transaction replication) the remote database to the central database server in a separate database and create a view that UNIONs both databases. Then insert and update in the physical databases, but use the view for reporting purposes. I'm a bit afraid such a view will be much slower. Perhaps this is an irrational fear since the underlying databases will be correctly indexed? Also this would mean some changes in the application.
Anyway, I was hoping for some feedback on this. Perhaps there are other ways to make the above happening?
