hi!all
i want to synchronize 2 sql server database resides at diffrent locations.
i want steps to do synchronization with the help of sql server enterprize manager as well from Sql - Dmo and VB.
:confused:
Thanks all in advance.
I have two SQL Server Database, one is at my company and one is at my company's customer. There are two related databases and two related tables in the servers. When I make a change in the table at my database, I want these changes to be done at the other server. I mean the related tables should have the same records all-time. I made a search and found that "Linked-Servers" is a good idea in this scenario. I made a linked server and run the following query in the Query Analyzer;insert into SAMPLE_LINKED_SERVER.SAMPLE_DATABASE.dbo.SAMPLE_TABLE(id,name) Select id,name From MY_SAMPLE_TABLE Where id Not In (Select id From SAMPLE_LINKED_SERVER.SAMPLE_DATABASE.dbo.SAMPLE_TABLE)This query works as I wanted. But I want this process to be done automaticaly without user interaction. Should I use Trigger? Do you suggest using Linked Servers?Or is there any other methods to make synchronization between two SQL Server Database?If I cannot find a good method in SQL Server, then I will be forced to make this synchronization by writing .NET code, but that would be difficult I think. Any suggestion and comment is wellcome.Thanks in advance.

I need to create a synchoronization with the Server Mobile (displayed in the Pocket PC emulator) once the website (SQL server Database) is updated. Is there any coding available? How is it possible? PLSSSSS HELP ME....
Does Sql Server Compact Edition 3.5 support RDA synchronization with Sql Server 2000 database?
We have been using Sql Server 2005 Compact Edition 3.1 RDA synchronization method successfully on Sql Server 2000 database. Recently we moved the database to Sql Server 2005, sync doesn't work anymore, it just hangs on one table. On further investigation, we found out that it's the index on that table that causes this. We removed the index, it works fine. We are wondering the root cause, removing the index is not a solution for us. Any thoughts?. Thanks.

I want to do SQL Server DB Synchronization. The scenario is like this..
DataBase is presently on SQL Server 2005, When end user click on button or on some action event
all data to from the server should be fetched & should be saved on client m/c. Afer that when user click on button or on some
event, DB should be synchronized. i.e. if there is any change in Server Data, client data should be automatically update...
How can i achieve this using C#..
Plzzz Help!!!!!
I am a complete novice so I would appreciate any help or suggestions.
I have two databases : 1 development DB, 1 production DB (both are SQL Server)
I make changes to development DB on a daily basis and I need a method to bring these changes across to production DB.
Currently I query the selected table in the development DB and write the DataSet to an XML file.
##
objDataSet.WriteXml(Server.MapPath("xDataDictionary.xml"))
##
Once I go to client site (where production DB is located) I want to generate a DataSet (which I am able to do) and compare this DataSet with the DataSet created when I read in the XML file.
##
'read in XML file
XMLDataSet.ReadXML(Server.MapPath("xDataDictionary.xml"))
##
There is a unique identifier in the table and XML file called 'FieldID'.
What I need to do is compare DataSet (from Production DB) with DataSet from XML file.
If there is a 'FieldID' in the DataSet from XML file that IS NOT in DataSet from ProductionDB I want to insert this node/row into the database.
Any suggestions?

I was wondering if anyone knows if there is any software available or
if it is easy to implement the following.
We are running a SQL Server database locally in house and also have
the exact same database running on a hosted webserver. The data
changes on both versions of the database daily and what we need to do
is figure out a simple easy / cheap way to have the two databases
synchronize with each other every evening so that the data is exactly
the same every morning.
I would appreciate any input.
thanks

Hi Guys:
I am trying to synchronize my home sqlserver database with a database on my web hosting company. I am not really sure how to go about it, any suggestions?
Thanks
Dear all,
I am using SQL Server 2000 Ent/Dev edition. I have a 2 identical database in 2 different servers and i'm required to synchronize both database. However, i need to exclude some of the tables in during this process.
I tried to search this forum but can't find any solution. How can i perform the above task? BTW i can't use trigger as i have more than 100 tables.
HOpe someone can help. Thanks.
Hi,
I am having this scenario; I have 2 SQL Server 2005 databases, they are basically identical in structure. The first one is used by my web application and the other is by desktop application ... I created the web db for security reasons ,.. i dont want online users to have access to the major backed (desktop db) directly so the web app is writing to the web db ... now, I want to update my major backend as transactions to the web db happen and vice versa to keep the users of both applicaions happy ... Is there a good design patterns for that? I am thinking of using db triggers for this but not sure on the implementation details ...
Your help is much appreciated
Hi,
I'm currently working on a Database Synchronization project and I wondered if anyone had any ideas other than what I've got so far. The context of this project is that we have a central server which stores data for 10 different locations in a consolidated database. Each store contains a replica of that database, but with only data relevant to their own operation.
Store owners can change data at the store level or chain owners can change data at the central level, but for either change the other level has to be notified. I currently have 2 ideas on how to do this.
Note: I am using MS SQL Server 7 for the central, but MSDE (Desktop Edition) for the store levels. So, replication from the store to the server is not available. I think I need to actually code this on my own.
Please can somebody help me with the following:
Our company has an enterprize site (a very large one). From time to time we need to make changes in it. In other words, we had to synchronize one database (local where we make all changes) and database on hosting. So, we did it manually (wrote scripts and inserted them in database on hosting). But as the databases grew it became impossible to synchronize everything manually. So we need some tool which could cope with this task. The problem is that, as I know, there are many tools which can do it, but we are tight in time and can't evaluate them all. Please share your ideas on what tool is worth evaluating?
Thanks in advance.
I am not a SQL developer by any means. I have a application to build for a Valet company that will require a laptop on site with no internet connectivity to function locally. There will be about 15 locations that all operate independently. After the day is done, the laptops will connect to the internet and upload all data to a hosted SQL server on the internet for centralized data storage and reporting. After a successful upload, the client database will be purged and start fresh the next day. Should this be doe with MYSql on the client and SQL server at the data center? I have some people recommending Progress database but it is expensive. I am out of my element when it comes to syncing db's so any advise is appreciated. Thanks-

I’m having three databases with same data in three different locations. Now three users adding records to the particular databases respectively. I want all the data from server A to be there at aerver B and C. all the updations at server B should be there at Server A and server C. as well as same updations at C also. It is not possible to implement replication as all the servers are at long distance. How can I update every database with the other server’s data? I’d like to update day wise. Is there any tool to generate script on that particular date period? Experts, I think you understood my scenario, please let me know the tools or list of best possibilities for me.
I’m thinking of Incremental backup. Guide me in this scenario.
Thanks in advance.
i have a web site which i must update frequently. i want to enter information in my client database and then transfer to web. how can i do this?

We need an architecture in which one office is in pune and other in mumbai,
principal server is in pune and mirrored in mumbai,
now we need an architecture in which mumbai user will performing read only operation from mumbai server (local server )and write operation in pune server(remote server)
and pune user will be performing read and write operation in pune server(local server)
now when link between pune and mumbai goes down, mumbai users will not be having acess to pune server so at that time mumbai user will not be performing write operation in pune server (local server) and when link goes up we want mumbai server to get updated with pune server.
how this is possible or any other different solution to this, what mandatory is we want mumbai users to perform read operation from mumbai server ONLY.

Just wondering if someone can tell me exactly what is happening during the "synchronizing" phase during db mirroring. Basically I have 2 questions regarding restoring and synchronizing.
1. Assuming there is no initial mirroring setup. A backup is taken from serverA. After the backup (and before the restore on serverB), there are several INSERTS being performed on the serverA. After which, the backup is restored to serverB and the servers are mirrored from A to B. Does the synchronizing state mean that all transaction logs are being synchronized and serverB will now have those newly inserted transactions?
2. Does this mean that as long as the transaction log is not truncated on serverA, serverB will always have an exact copy of the serverA database?
Hi all,

Can anyone help me how to proceed with it.
Thnks in advance for your help.

Hello everybody,
There is some strange behaviour i've recently noticed while watching synchronization progress in Replication Monitor on SQL 2005 Server Standard with merge replication configured. The merge process seems to repeat several times.
This is the initial synchronizaion (reinitalization at the subsciber). Client is using Microsoft.SQLServer.Replication objects from .net framework assemblies.
The synchronization starts normally (status is "Running"). The last message of selected session box shows (among other messages): "Beginning evaluating partial replication filters" then "Finished evaluating partial replication filters" and finally "Merge completed after processing xxx changes... etc." after a few seconds. Status changes to "Completed" and then... the merge process starts again!! "Beginning evaluating partial replication filters" etc. And this repeats about 15-20 times.
And so whole process takes about 15 minutes instead about 45 seconds to complete initial synchronization. The number of changes is "Merge completed after processing ..." never change since the first such message.
Is this some bug in web synchronization or some invalid configuration setting? Why does merge process repeat itself so many times??
Please help, thanks in advance.

All- I'm a newbie working on a VWD project. A couple questions arose when attempting to work with a project's dataset and its underlying SQL Server Express database:
Is it true that when changing the schema of a database in SQL Server Express through the VWD Database Explorer, one must take care to manually make parallel changes in the dataset? For example, if you make a relation between two tables in Database Explorer, you must do the same with the counterpart tables in the dataset? For example, I find that if I delete or create a relationship between two tables in the database, I must manually do the same in the dataset.
Hi all,
I have a SQL Server 2005 Compact Edition database that synchronizes with a SQL Server 2005 Standard database via merge replication.
The problem I have is when I cancel a synchronization, the database is left in such a state that I cannot add any new records. I dug around a bit and have found that in the INFORMATION_SCHEMA.COLUMNS view, AUTOINC_MAX has been incorrectly set to the same value as AUTOINC_MIN for the primary keys, which explains the 'out of range' error I get in my program when running off such a database.
In contrast, a non-corrupted database has AUTOINC_MAX set to AUTOINC_MIN + 999, presumably because of my subscriber identity range of 1000.
If this is the only thing that has gone wrong, all I need to do is programmatically set the AUTOINC_MAX values to AUTOINC_MIN + 999, however I can't find out where to do this (and INFORMATION_SCHEMA.COLUMNS is a view so it can't be updated obviously.)
I have also heard that 'compacting' the database may help, but I don't know how to do this either!
Any help would be immensely appreciated!

Jonathan.

Dear All,
How to do Sql Server Synchronization.
Say:
Server "A" contains "123" database.
Server "B" contains "123" database.
But changes is made on Server A. I want that every changes made on server A "123" database should reflect on Server B "123" database on real time basis.
whether it is done through replication or any other way, i want practical answer so that i can try it out.
Thanks
I want to realize these steps in .net2005 C# programme:

3) Start Sqlserver2005 Subscription synchronization agent.
4) View Sqlserver2005 synchronization agent status, if it done then continue.
I tried to find some SP, dll, method or script to realize this funtion, but failed.
I really need help.
A thousand thanks for your patience.
Hi all
I have two SQl Server 2000 in two different location, at one point I wand to Transfer the information in one table (in Sql server 1) to the same table (in SQl server 2) using Stored Procedure.
Can any one through some input on how to write the SP?

We are working on data synchronization application. This application will synchronize data which are stored in flat file on several client machines generated by windows application to central database (Probably My SQL or SQL Server).
This application/agent will continuously monitor all the modifications done by windows application on client machine and then synchronized data with the central database.
Currently we are looking for unidirectional synchronization i.e. from client to server only.
If you have worked on similar kind of project, it would be great help if you share technology/architecture used in your application.
Thanks & Regards,
Jugal Shah
I have a VB app which stores information in an Access 2000 db. The VB apphandles multiple users (it's a logbook type of application, users sharelookup tables but don't share information among themselves - IOW, I couldn'tsee your log entries and you couldn't see mine).We're adding a web interface to the package - basically a scaled down dataentry interface to allow users to add log entries without being at theirworkstations. The web version will be storing data in a SQL Server 2000 db.I need to be able to synchronize data between the two - if a usersedits/adds a log entry in the desktop version, they need to be able tosynchronize the desktop and web (this is done via a button click, no"realtime" updates). Same scenario with the web side, but the web interfacewon't acutally be able to synch with the desktop - the user would have toinitiate the synch from their workstation. We've pretty much worked out thesynch logic path, and we're working on acutally interfacing with the SQLServer.Can this be done reliably using a standard ADO connection between thedesktop and the web site? I would imagine traffic would be somewhatminimal - on average, no more than 100 records would be added or updated.I've done some testing on this, and with 20 - 50 records it seems to workfine both ways.Suggestions of better/more reliable methods would be most appreciated, andthanks for your time

Hello EveryoneWe have a third party tool which maintains its own customdatabase,DB1 on SQL Server 2000 on Server A (Windows 2000). We built aninhouse application which maintains a transactional database, DB2 alsoon Server A derived from DB1. Since the DB1 is frequently updated thesynchronisation between the databases is currently maintained by usingviews in DB2 which pulls in all the required data from across tables inDB1.But we found that the cost of employing views, referencing tablesacross databases has made the inhouse application slower and so as aapparent performance tuning measure we plan to maintain a subset ofdata(for a specific time period) from DB1 in actual tables with sameschema in our transactional database DB2. But since the tables in DB1are frequently updated during the day we are required to thesynchronise the corresponding tables in DB2 with their counterparts inDB1. The only constraint in this synchronization being that the thirdparty custom database,DB1 cannot not be subjected to any changes (likecreation of triggers) as it is maintained by a different group ofpersonnel.I read about Triggers,Maintenance Jobs and Replication but not surewhich would suffice our needs.Are there any recommendations on how thiscould be carried out? Any suggestion would be welcome.Thankschandra
