Synchronization Of Database At Different Location
Jun 19, 2008
Hi all,
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.
Regards,

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,
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-

Dear All,
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 had to to relocate the database log file and I issued an Alter database command but by mistake I put a space in the file name as below. The space is at the beginning file name. Now I am unable get the database loaded to SQL Server. The database has 2 replications configured, so deleting and re-attaching the database means the replication needs to be re-configured. Is there an alternative way to issue a command to update the database FILENAME ? Not sure if this can be edited in master database (sys files).
ALTER DATABASE [User_DB]
MODIFY FILE (NAME = User_DB_log, FILENAME = 'I:SQLLogs User_DB_log.ldf')

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.

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?

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.

Greetings, I have just arrived back into the country (NZ) and back into ASP.NET.
I am having trouble with the following:An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
It has only begun since i decided i wanted to use IIS, I realise VWD comes with its own localhost, but since it is only temporary, i wanted a permanent shortcut on my desktop to link to my intranet page.
Anyone have any ideas why i am getting the above error? have searched many places on the internet and not getting any closer.
Cheers ~ J

Got a couple of questions
1. If you are managing databases in SQL Express with SQL Server Managment Express CTP, why doesnt VBE place the database there where you can see them? I can create a database inside SQL Server Managment Express CTP and view its tables, relations,etc. from within SQL Server Managment Express CTP, but when I make a database with VBE it does not show up in SQL Server Managment Express CTP. Also the database that was made inside SQL Server Managment Express CTP cannot be seen from VBE. Why? what did I do wrong, or is it supposed to be like that? Is that where you would want to place a database for multiple pc to share?
2.Login Question ;-----shouldnt post this here but,
Is there a reason why you dont want to use SQL Authetication over Windows? The are a few pcs here that doesnt have user accounts installed(I know that not a good practice, but when you have multiple people needing different data quickly- switching users is not preferred, its a time thing for what I would call dummy terminals).
How do you take an instance of SQL and change to SQL Authetication over windows?
Curious?

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.

Later On I would need to instal the ClickOnce setup of this application on a server in so everyone can reach it. is the the ClickOnce setup sufficient for this task. and will the database be added to the SQL SERVER databases ?

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!
Regards,
Jonathan.

If you enter "Create Database test", the database files (mdf file & log file) are created, by default, in:-
C:Program FilesMicrosoft SQL ServerMSSQLData
I want to change that to:-
D:Database Files
I sucessfully moved the model database to this location (using the instructions in BOL) assuming that all new databases would now get created in the same location, but they don't. They still get created in:
C:Program FilesMicrosoft SQL ServerMSSQLData
So how do I change the default?
(It's not satisfactory to have to move each database after it's created)
Thanks, Andy Abel
