Hi!
I'm setting up a merge replication for sql ce. Ten guys with windows mobile 5 pocket pc works as service technicians and need to synchronize data in the field.
The backend database is huge and I just want each person to have their own data on the pda and synchronized, they have unique userid's in the database. Is it possible to filter data for each person or do all have to have all data that's in the backend database?

What is the main difference between snapshot and transactional and merge replication?
View 5 Replies View RelatedHi 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).
Hi pros,
We now have a business requirement to use SQL Replication to replicate our Live Database Server to a Live Reporting Server. So updates will be in one direction.
I wonder if someone with some experience in this area can give me a rough idea of what I'm getting myself into.
How good is SQL Replication?
How much time am I going to spend reading up before I'll know enough to do this?
What kind of a footprint does it leave on the server?
How much more complex does it make maintenance and DB upgrades?
What's the lag time? If a user updates a record on the Database Server and then emmediatly runs a report on the Reporting Server, will they see that change reflected?
PS: Anyone know what Robvolk is doing these days? I miss that guy. He's one of the few good ones left.
There aren't many primary keys on the tables in the Publishers. If I add primary keys to the tables on the replicated database, when I subscribe again to the Publications, will they disappear from my replicated database (i.e. will the schema be overwritten)?
View 3 Replies View RelatedI was told to do the DTS which synchronizes the data between Informix and MS SQL server. First, I am not allowed to touch the Informix server. Is that possible to do the pull replication subscription from the SQL Express that does the extraction/update from Informix? I tried it out already but I didn't see any publication. umm.. my Informix is not loaded in windows machine. Thank you very much.
View 1 Replies View RelatedRight now we use autogenerated primary keys in various tables of our SQL server 2005 database. Now we have a need to put separate database servers at various remote locations and data will need to sent back to the central server. Some data will be sent back from central server to the remote sites. Data also gets added at the central location.
How can I handle replication when using autogen keys? Can I add some additional column like a SiteID and make the primary key a combination of Autogenerated key and Site ID? Would that work? The autogenerated primary keys are also foreign keys in other tables.
I have read a little about having separate ranges (of autogenerated keys) for various sites but don't think that will work as we already got lots of data in our central server.
Any help is much appreciated.
Hi all
My company is going to open new working centers on different locations of my region. One of the problems we are suffering is that at some locations, the network communications infrastructure is very very very poor. So, in that locations we work with low bandwidths, and connections usually break down.
Because of this, we are thinking in distributing our database. I have been doing some tests on replication, reading the docs, etc... But I am still not sure which replication strategy should we use, and how to organize our database tables to allow replication work properly.
Our offices are going to share some data (a product catalogue, for example) which could be updated an queried from any of the offices. But there is also data which is not going to be shared, as product stocks for each location.
We were thinking on using transactional peer-to-peer replication. But now we are having serious doubts about this since in a previous post (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1525643&SiteID=1) we were told we can't store non-shared data (stock) in the same table as the shared data (products) due to how database behaves when a publication is restarted. We know it would not be usual to republish, but we were thinking on crash recovery.
It would be fantastic if somebody could help us to decide what should we do to organize our database to allow the use of a proper replication scheme.
Thanks in advance,

hi there! i am a newbie with replication. i am trying to implement one, however due to lack of references, there are some difficulties. here are some of my questions, i am hoping anybody could take their time to help me out in details. Thanks and appreciate it!
(1) i could not publish all tables. tables that do not have primary keys are not included, and i need to publish all tables.
(2) tables that i sucessfully published does not replicate the table's primary keys, relationships and triggers, how do i update the subsciber?
(3) for some reason, i could not replicate schema objects - views, UDFs, stored procedures. its giving me an error.
Please advise.
Again, thank you so much!
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...
Hi everbody,

Hi,
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.
Please help me anybody.
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!
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.

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....

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.

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.
please help me out
thanks
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!

Anybody tell me about implementation of oneway merge replication.

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

Can you merge replicate data from SQL Server 7.0 to SQL Server 2000?
View 1 Replies View RelatedI 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
I've tried to configure merge replication between SQL2005 and SQL Express use Web synchronize but the status of subcription is always uninitialized although I reinitialized it.
Could you tell me the way to start it ?
Thank so much.
