I have a problem with merge replication and mirror. I have
Principal server: B is subscriber of A.
Mirror server: D is subscriber of C.
F is distributor and also witness.
D is mirror of B.
C is mirror of A.
I also set parameter PublisherFailoverPartner for Merge agent and log reader agent.
1. Merge replication between A and B is ok
2. Mirror between D and B is ok
Mirror between C and A is ok
3. When i failove, merge replication between D and C does not work. The message is shown
The merge process could not connect to the Publisher 'SGIMIS-2:Mis'. Check to ensure that the server is running. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147199368)
Get help: http://help/MSSQL_REPL-2147199368
Another merge agent for the subscription(s) is running or the server is working on a previous request by the same agent. (Source: MSSQLServer, Error number: 21036)

Hi i have tried a search on this topic but didn't find much.
I have my fiest sql db live on my we server and all works fine, more luck than skill i think.
But now i wory about backing up my data i have tried various tools backing up the db every 5 minutes and then sending it too another server via ftp this tool works fine but when we have a few people on and the db is accessed frequently it can't back it up i assume this is to do with the backup tool needing an exclusive lock on it.
What is the difference between Replication and data mirror both of these seem to be talked about alot and is there a simple guide somewhere on how to set these up.
Or if i am coming at this from totally the wrong angle then please let me know
I'm trying setup a proof of concept for a client but I€™m having issues with mirroring and replication.
With the help of http://technet.microsoft.com/en-us/library/ms151799.aspx I€™ve done the following..
The setup is as follows, I have several instances of SQL Server
A+B are mirrored with each other, with A being the principle and B the mirror
C is the distributor
E is subscribes to A, with parameters for PublicationFailoverPartner set to B
The mirroring between A+B works fine, I can manually fail each and the databases keep in step.
Without testing the mirroring failover, the replication between A+C+E also works.
However when I test the mirror to failover between A+B no transactions are replicated though to E. The publication moves from A to B in the Server Management Studio.
The logs state that the log reader agent can not gain access to A, however nothing is recorded regarding any attempts to contact B. In the replication monitor the error message
"The concurrent snapshot for publication ABCXYZ is not available because it has not been fully generated of the Log Reader Agent is not running to activate it. If generation of the concurrent snapshot was interrupted, the Spapshot Agent for the publica..." (cut off).
"the process could not execute 'sp_replcmds' on 'A'
I have checked that the SQL Server Agents are running on all agents,
I have checked that that server B is set at the PublisherFailoverPartner on server C agent configuration; I'm now at a lost as to what is wrong,
We have SQL 2005 db mirror configured with a witness server for high availability. Node 1 is the principal and Node 2 is the mirror. A nightly job creates a snapshot on Node 2. The snapshot is used for previous day reporting queries. We have now been asked to present another copy of the database for near-time reporting. I thought about possibly adding a peer-to-peer replication as part of my environment but was hoping to see what everyone else out there is doing.
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 SQl Server 2012 Database Mirroring with around 40 gb as mdf and 1 gb as ldf. Now my ldf size increased . How to reduce ldf size while mirror enabled with mirror server and witness server. Can shrink the ldf with mirror enables.
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??
SQL Server replication requires the actual server name to make a connection to the server. Connections through a server alias, IP address, or any other alternate name are not supported. Specify the actual server name, 'xxxxxx'. (Replication.Utilities)
After adding the Witness Server to the Mirror session, the Witness Connection state between the Mirror and Witness Connection is Disconnected and the state between Principal and Witness Connection is Connected.
The procedures defined in Books Online was used to setup Database Mirroring...when the Witness server was added to the Mirror session, only the alter database T-SQL statement was executed on the Principal server.
ALTER DATABASE <db_name> SET WITNESS = 'TCP://<servername>:<port>'
After executing the above statement, a few seconds later the state between Principal and Witness Connection changed to Connected and the state between Mirror and Witness Connection remains Disconnected.
The Mirror session is not using Certificates, every server is on the same domain, using the same domain login account, and all servers have SP2 installed running Enterprise Edition.
Any idea's why the state between Mirror and Witness Connection remains Disconnected?
I was trying to test mirroring and now would like to delete the mirror database but it says I need to remove database mirroring first. I deleted the endpoint and cannot figure out how to remove the mirroring. Can someone please help.
Hi everbody, I setup the Merge Replication , it is working perfectly. But i have one problem now it is updating both ways. I nedd one way. Any body tell me which parameter i have to change.
My production box is running on NT4.0,SP6, SQL Server7.0,SP2. We implemented Merge replication. Working fine last 7 months. Last weekend i disabled replication, Successfully removed Distributor and Publishor. After that try add new fileds but won't allowed me. It's give the error message. I Also found Some Conflict_tables found almost 20 tables. All system Tables. Can delete these these tables, if i delete any problem my database. I added filelds many times but this time i got errors.
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.
I have implemented a Merger replication on our development server and I get a fillowing error when I try to update one of the table in publisher. "Transaction cannot start while in firehose mode"
Hi, I read some where that replication has two types conflict resolution, 1. row based and 2. Column based... If I am right... Can any one point me how to find out this option and how to set it up....
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.
I have successfully tried merge replication on single server with 2 databases. now i want to do the same with different servers, when i create pull subcription on server 2 which user account should I use? it is giving log in failure i tried using windows admin account and also the 'sa' account.
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.
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!
I had set up merge replication. I got these error messages where replications starts "Column names in each table must be unique. Column name 'PubID' in table 'bonflict_DBName_PHP_Data_Publications' is specified more than once "

Is it possible to modify or add new fields in sql 2000 when the instance became publisher ? I tried it several times but it failed. I access microsoft website but i did not help.
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.
hi, in merge replication,i make a request subscriber with a priority 25.00,when i update the same date,it always choose the update from the publishing server,why????how does it work??? thx inadvance

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
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?
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!
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?
