Saving Passwords In Windows Synchronization Manager
Sep 22, 2006I am using Windows Synchronization Manager to sync up a web based Merge Replication. Is there anyway to get Windows Synchronization Manager to save the passwords for the distributor, publisher, and the basic auth for the web server? I know the easy way would be to use windows auth by that is not an option in my scenario.
It is a pain to have to type them in everytime I want to sync my databases...
Web Synchronization - Completed Synchronization Starts Again
Sep 6, 2006Hello 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.

SSIS Data Source Vs Connection Manager Synchronization Issue
Apr 25, 2007I changed one data source settings in my SSIS project to use Windows Authentication instead of SQL Authentication. This data source is used to create connection managers in all SSIS packages. Soon after the data source was changed, when I opened any package using the connection manager that is based on this changed data source, I got an alert message box like the one given below showing different connection strings in data source and package connection manager. That's understandable (why can't VS 2005 do this silently or give an option to let this happen silently? that would be nice.).
Here is the problem. Even after both data source and connection manager are synchronized, still the same message box keeps on coming when ever I open any affected package (about 20 packages!). It is very annoying as you can see that old and new connection strings ARE IDENTICAL, still VS 2005 is not able to recognize this. I installed VS2005 SP1 even before I ran into this problem. I asked my friends to open this project and check the behavior on his machine. Same thing. Is this a known bug? How to fix this problem? Thanks for your help.
=====
Message box "Synchronize Connection Strings" (VS 2005 status bar shows "Performing post package load operations"):
This package contains at least one connection which is based on a datasource. The connection string for conenctions and data sources listed below are currently not identical. Connection strings of connections will be updated to reflect those on the datasource.

Feb 19, 2007Hello guys!
I went through the bunch of documentation pages about configuring the one for providing web subscriptions.
The most usefull for me were:
Security Architecture for Web Synchronization
How to: Configure an IIS Server for Web Synchronization (SQL Management Studio)
How to: Configure a Subscription to Use Web Synchronization
Topologies for Web Synchronization
Securing the Publisher
Subscribing to Publications
Mssubscription_properties (Transact-SQL)
How to: Configure a Subscription to Use Web Synchronization (Replication Transact-SQL)
sp_addmergepullsubscription (Transact-SQL)
Web Synchronization for Merge Replication
But I still have questions about it. If you could help me with small notes about subscribing to web based merge publication I would really appreciate that!
I believe, I just need a bit of clarification. The target setting is simple as it is: a client should connect to the our hosting server via HTTPS and update his pull subscription on demand by running .NET application.
Avoiding the server part, are the following steps correct and enough to accomplish what I need?
1. To create subscription, should I use the script:-- This script uses sqlcmd scripting variables. They are in the form-- $(MyVariable). For information about how to use scripting variables -- on the command line and in SQL Server Management Studio, see the -- "Executing Replication Scripts" section in the topic-- "Programming Replication Using System Stored Procedures". -- Publication must support anonymous Subscribers.-- Execute this batch at the Subscriber.DECLARE @publication AS sysname;DECLARE @publisher AS sysname;DECLARE @publicationDB AS sysname;DECLARE @websyncurl AS sysname;DECLARE @security_mode AS int;DECLARE @login AS sysname;DECLARE @password AS nvarchar(512);SET @publication = N'AdvWorksSalesOrdersMergeWebSync';SET @publisher = $(PubServer);SET @publicationDB = N'AdventureWorks';SET @websyncurl = 'https://' + $(WebServer) + '/WebSync';SET @security_mode = 0; -- Basic Authentication for IISSET @login = $(Login);SET @password = $(Password); -- At the subscription database, create a pull subscription -- to a merge publication.USE [AdventureWorksReplica]EXEC sp_addmergepullsubscription @publisher = @publisher, @publication = @publication, @publisher_db = @publicationDB, @subscriber_type = N'anonymous'; -- Add an agent job to synchronize the pull subscription. EXEC sp_addmergepullsubscription_agent @publisher = @publisher, @publisher_db = @publicationDB, @publication = @publication, @distributor = @publisher, @job_login = @login, @job_password = @password, @use_web_sync = 1, @internet_security_mode = @security_mode, @internet_url = @websyncurl, @internet_login = @login, @internet_password = @password;GO
What is @job_login parameter here? As I understand, I will not run SQL Agent job as our client uses MS SQL Server 2005 Express. And I do not want to run it as we will provide a client with .NET application for performing synchrinization on demand
Parameter @publisher means full SQL Server instance name? For example, MYMACHINEMSSQLSERVER?
What user will be used to connect to the distributor and to the Publisher? Will it be @internet_login?
Do I need running sp_addmergepullsubscription_agent if I€™m going to use the following .NET application code to synchronize over the Internet?
2. To perform synchronization with our hosting servers, should a client use the following code?
// Define the server, publication, and database names.
string subscriberName = instanceName;
string publisherName = instanceName;
string publicationName = "AdvWorksSalesOrdersMerge";
string subscriptionDbName = "AdventureWorksReplica";
string publicationDbName = "AdventureWorks";
string hostname = "adventure-works\garrett1";
string webSyncUrl = "https://" + instanceName + "/SalesOrders/replisapi.dll";
// Create a connection to the Subscriber.
ServerConnection conn = new ServerConnection(subscriberName);
MergePullSubscription subscription;
MergeSynchronizationAgent agent;
try
{
// Connect to the Subscriber.
conn.Connect();
// Define the pull subscription.
subscription = new MergePullSubscription();
subscription.ConnectionContext = conn;
subscription.DatabaseName = subscriptionDbName;
subscription.PublisherName = publisherName;
subscription.PublicationDBName = publicationDbName;
subscription.PublicationName = publicationName;
// If the pull subscription exists, then start the synchronization.
if (subscription.LoadProperties())
{
// Get the agent for the subscription.
agent = subscription.SynchronizationAgent;
// Check that we have enough metadata to start the agent.
if (agent.PublisherSecurityMode == null)
{
// Set the required properties that could not be returned
// from the MSsubscription_properties table.
agent.PublisherSecurityMode = SecurityMode.Integrated;
agent.DistributorSecurityMode = SecurityMode.Integrated;
agent.HostName = hostname;
// Set optional Web synchronization properties.
agent.UseWebSynchronization = true;
agent.InternetUrl = webSyncUrl;
agent.InternetSecurityMode = SecurityMode.Standard;
agent.InternetLogin = winLogin;
agent.InternetPassword = winPassword;
}
// Enable agent output to the console.
agent.OutputVerboseLevel = 1;
agent.Output = "";
// Synchronously start the Merge Agent for the subscription.
agent.Synchronize();
}
else
{
// Do something here if the pull subscription does not exist.
throw new ApplicationException(String.Format(
"A subscription to '{0}' does not exist on {1}",
publicationName, subscriberName));
}
}
catch (Exception ex)
{
// Implement appropriate error handling here.
throw new ApplicationException("The subscription could not be " +
"synchronized. Verify that the subscription has " +
"been defined correctly.", ex);
}
finally
{
conn.Disconnect();
}
What does HostName parameter use for? What is that host? Subscriber€™s machine name instance name? Or Publisher€™s? Or Distributor€™s?
Why parameters PublisherSecurityMode and DistributorSecurityMode have value SecurityMode.Integrated? How it is used in the replication model for web synchronization? As I understood from the documentation, client (Merge Agent) should connect to the Subscriber, get the changes, connect to hosting server via HTTPS and perform transactions through the SQL Server Replication Listener, thus the internet login to the IIS should be used to perform all the operations on hosting server side? The same internet login will be used to get snapshot from UNC share?
If I€™ve chosen to use FTP to provide with snapshots, should I then provide ftp parameters to sp_addmergepullsubscription_agent stored procedure or they will be used automatically by ISAPI filters on hosting server?
Thank you.

Mar 24, 2006Hello,
I'm having to build a smart client application that works with an offline sql express database on the client. And works with several types of databases - that may be configured to work as a central server. The list includes the sql server family including 2000, 2005 and express and also IBM DB2.
I have to address some rather complex merge replication scenarios. By Merge I mean the ability to deal with handling and synchronization of bi-directional changes. More specifically changes to data may be made to any database in the system. either local or central.
I'm afraid, I cannot use sql replication in a heterogenous mode for several reasons. Some being - the database is being auto attached on the client, the application is expected to live up to the 'low impact' install ideology and should not need any major configuration etc.....
Are there any recomended approaches/Ideas one may use to acheive replication. Any links/information/ideas will be great.
Thanks,
Avinash

Synchronization With RDA
Jan 31, 2008
Hi!
I'm developing a Windows Mobile solution (Pocket PC Win 5-6). I have Sql Server CE on the device and I use RDA (Remote Data Access) to pull the tables to the Sql Server CE. I use RdaTrackOption.TrackingOffWithIndexes so I can Alter the table design. Then I use the function SubmitSql to push back my changes. On the server I have a table for example Customers, it has a column called CustomerId with identity(1,1). Let's say the highest Id is 100 and the lowest is 50, when I add a record in the Sql Server CE it gets CustomerId = 1 then next one 2 etc which means identity is working but does not continue after 100. I don't need to use the CustomerId when I push my data back because I have sql syntax taking care of @@IDENTITY when inserting new records. Anyone who knows why it begins on 1 and not 101?

Database Synchronization Using XML
Jun 16, 2004I 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?

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

My Synchronization Scenario
Sep 22, 2005Hi, I want to know the a solution for my Synchronization Scenario
I have a several client databses which are SQL Server 2005 Express and i have a master database which is SQL Server 2000 containing all the individual Client databases. All the individual client databases are kept seperately at the master location. I need to Synchronization the client database with its copy at the master database (something like Merge replication). Both the Client Copy as well as Master Copy could be Publishers & Subscribers.
Now the problem is Because of security & firewall issues, only the Client should have the ability to schedule & initiate the synchronization process with the master copy. Unfortunately SQL Server 2005 Express has only subscriber agent and not a publisher agent.
Any help on how to achieve this would be appreciated . Thank You

Database Synchronization
Mar 10, 2004Hi,
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.

Apr 16, 2008Please 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.

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.

Reliability During Synchronization
Apr 11, 2007I am using SS05 64 bit standard edition, SP2 on a 2.8 GHz dual core Xeon 2 GB RAM box with a 146GB RAID 10 data partition and a 36GB mirrored OS partition.
I have 13 publications over 5 databases. Some of these publications are transactional, some are merge with updating subscribers.
I have 35 pull subscribers that use Windows XP SP2 and Sql Express SP2, and connect through wireless broadband, wired broandband, or a dial-up connection. I am not using web synchronization.
I am experiencing a high failure rate during synchronization with a variety of error messages, such as "The merge process could not replicate one or more INSERT statements to the 'Subscriber'. " Another error would be "The replication agent has not logged a progress message in 10 minutes. This might indicate an unresponsive agent or high system activity. Verify that records are being replicated to the destination and that connections to the Subscriber, Publisher, and Distributor are still active.".
.Some of these errors seem to be the result of a hiccup in the connection. These hiccups cause synchronization to fail where a normal file transfer would succeed.
I know this is a vague question, but is there any way to make this process more reliable?
Thanks in advance for your suggestions.
