I have a Merge Replication Problem and I'm not sure how to proceed.
Given the following:
Multiple clients have merge subscriptions to a central Server's DB.
DB contains a table tblUser
tblUser has a Varchar field; UserLoginName, which is Primary Key.
It also has an integer field, UserValue
The replication is configured to resolve to the greater integer value.
Client 1 creates a new User
INSERT tblUser
(UserLoginName, UserValue)
VALUES('Fred',1)
At the same time Client 2 does the same thing, but with a larger value
INSERT tblUSer
(UserLoginName, UserValue)
VALUES('Fred', 2)
One of the inserts will get to the Central Server first.
The other will form a conflict.
A row insert at 'Client2.dbUsers' could not be propagated to 'CentralServer.dbUsers'.
This failure can be caused by a constraint violation.
Violation of PRIMARY KEY constraint 'PK_tblUser_1'. Cannot insert duplicate key in object 'dbo.tblUser'.
So now I have two different value fields and a conflict that cannot be resolved.
Is this fixable?
Do I need to make changes at athe Architechture level?
I got a problem with merge replication. I got a central sql server 2005 database on which i got a publication. Also there are 2 sql servers CE which are subscribers to that publication. I need to add some records on both mobile servers indepently but i'm using primary key as a user id in one table. So when i add a user on one PDA i use next available number in column ID. In the same time I add a user on other PDA with the same ID, because I don't know that there is such user with the same ID. Ok then I do synchronization. First PDA synchronizes with server but second tells me that there is a record with the same PK. And my question is. Can these be resolved writing a custom resolver or maybe you know others resolutions, because I think that is a typicall problem but couldn't find any solution other than using ie. HOST_NAME() function.
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'm using a Merge statement to update/insert values into a table. The Source is not a table, but the parameters from a Powershell script. I am not using the Primary Key to match on, but rather the Computer Name (FullComputerName).
I am looking on how-to return the Primary Key (ComputerPKID) of an updated record as "chained" scripts will require a Primary Key, new or used.As an aside: the code below does return the newly generated Primary Key of an Inserted record.
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??
I am trying to append records from one table to another in a db running onMSDE, knowing fullwell that some of the data in the source will beduplicates of that in the destination table's pk.What I would like to happen is to have the stored procedure plunk in allrecords that don't violate the constraintand silently let the duplicate info fall by the wayside. The trouble is SQLserver seems to abort the whole procedure ifeven a single record violates the constraint.In a regular Access mdb, an INSERT statement (append query) would do justthat. Of course it warns you of the violation but a DoCmd.SetWarnings FALSEtakes care of that.Any ideas as to what I need to do to achieve that same thing?
I am transferring data from one SQL table to another. The first table has a PK on the unique id only, the second table has PK on five fields (the idea being to reject duplicate records etc. etc.). I am using a DTS package to do this, but when run it will fail when it hits a PK violation. How do I getround this??????? What simple thing am i missing??
Hello! I have a "current" table which users update on a daily basis, it holds forecast data. This table is designed to only hold 7 days of data and is therfore always rolling over by date. What I want to do is have a procedure that copies this "Current" table to a "History" table every day so the historical information is stored. The copy is simple, but how do I check for and over ride values that are already in the "history" table with the newest values from the "current" table because the "current" values have the possibility of changing a few times while the forecast is updated. I can define a primary key but am not sure how to check for and update the necessary values?
I'm trying to optimize a few batch import procedures we use in our processes.
It currently works like this:
1) Cursor loop cycles through all data to be imported from IMPORT table
2) For every record there is an attempted insert to PROD table in a TRY-CATCH check to see whether the record would pass all the primary key and foreign key constrains in PROD table
3) Only those that pass the TRY-CATCH check gets imported into PROD table
4) Every row gets logged into a separate LOG table, either with a comment like "Import OK" or "Error: foreign key violation in field 'my_id'"
The thing is, the procedure runs fine when I'm importing several thousands of records, but when it comes to hundreds of thousands, the speed becomes an issue, as I currently get 20 records per second and slowing...
There is no other code in that procedure, no queries. Just the Cursor cycle and the try-catch check.
I am a SQL DBA involved in accomplishing various activities using Enterprise Manager by regestering servers of various countries.
Now as the NT Team has gone for auditing implementation in all the servers in OS lever, they find Access violations from the workstation from where I connect to the server. This does not happens if I unregester the Servers from Enterprise manager and use only query analyzer.
Note: We have our own users in OS as wel as in SQL SERVER .
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!
