Thanks Mahesh, the above suggestion
did work. However, I have a new problem with SQL Server mobile subscription. I
use SQL server 2000 and SQL server management studio from SQL 2005. After the Synchronization
start, I have following error
€œThe constraint cannot be removed
because it is referenced by another constraint. [ Constraint name =
specCategories ] HRESULT 0x80040E90 (25077)
The SQL statement failed to execute.
[ SQL statement = drop table "specCategories" ] HRESULT 0x80040E90 (28560) €œBut there is no constraint for specCategories, it only has foreign key in table "Specs"
I'm trying to configure web synchronization using the wizard, It errors out on step "Setting The snapshot share permissions". The error I get is
The operation completed successfully. (Exception from HRESULT: 0x80070000)
Then all the other steps rollback. I'm using the default location for the snapshot i.e in REPLDATA folder. When creating the publication I used a UNC path to specify the snapshot folder. For testsing purposes I'm using a windows account that has admin privilages on the box that is running IIS. I'm just testing this merger replication over https, so I have IIS and the distributor on the same box. I created the publication, and the snapshot. I was walking through the wizard, all seems to be OK but can't get past this pesky error, which is strange seeing it says it complete successfully.
I have something called Configure Web Synchronization Wizard under my SQL Server 2005 Mobile Edition on my XP machine. My problem is that I need to install it on a Windows 2000 machine and I can't find the installation package for it. I installed SQL Server 2005, which installed SQL Server 2005 Mobile Edition, but I didnt' get the wizard. I also installed Visual Studio 2005.
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??
I am trying to create table with following SQL script:
Code Snippet
create table Projects( ID smallint identity (0, 1) constraint PK_Projects primary key, Name nvarchar (255) constraint NN_Prj_Name not null, Creator nvarchar (255), CreateDate datetime );
When I execute this script I get following error message:
Error source: SQL Server Compact ADO.NET Data Provider Error message: Named Constraint is not supported for this type of constraint. [ Constraint Name = NN_Prj_Name ]
I looked in the SQL Server Books Online and saw following:
CREATE TABLE (SQL Server Compact) ... < column_constraint > ::= [ CONSTRAINT constraint_name ] { [ NULL | NOT NULL ] | [ PRIMARY KEY | UNIQUE ] | REFERENCES ref_table [ ( ref_column ) ] [ ON DELETE { CASCADE | NO ACTION } ] [ ON UPDATE { CASCADE | NO ACTION } ]
As I understand according to documentation named constraints should be supported, however error message says opposite. I can rephrase SQL script by removing named constraint.
Code Snippet
create table Projects( ID smallint identity (0, 1) constraint PK_Projects primary key, Name nvarchar (255) not null, Creator nvarchar (255), CreateDate datetime ); This script executes correctly, however I want named constraints and this does not satisfy me.
I have become frustrated and I am not finding the answers I expect.
Here's the gist, we support both Oracle and SQL for our product and we would like to migrate our Clients who are willing/requesting to go from Oracle to SQL. Seems easy enough.
So, I create a Database in SQL 2005, right click and select "Import Data", Source is Microsoft OLE DB Provider for Oracle and I setup my connection. so far so good.
I create my Destination for SQL Native Client to the Database that I plan on importing into. Still good
Next, I select "Copy data from one or more tables or views". I move on to the next screen and select all of the Objects from a Schema. These are Tables that only relate to our application or in other words, nothing Oracle System wise.
When I get to the end it progresses to about 20% and then throws this error about 300 or so times:
Could not connect source component. Warning 0x80202066: Source - AM_ALERTS [1]: Cannot retrieve the column code page info from the OLE DB provider. If the component supports the "DefaultCodePage" property, the code page from that property will be used. Change the value of the property if the current string code page values are incorrect. If the component does not support the property, the code page from the component's locale ID will be used.
So, I'm thinking "Alright, we can search on this error and I'm sure there's an easy fix." I do some checking and indeed find out that there is a property setting called "AlwaysUseDefaultCodePage" in the OLEDB Data Source Properties. Great! I go back and look at the connection in the Import and .... there's nothing with that property!
Back to the drawing board. I Create a new SSIS package and figure out quickly that the AlwaysUseDefaultCodePage is in there. I can transfter information from the Oracle Source Table to the SQL Server 2005 Destination Table, but it appears to be a one to one thing. Programming this, if I get it to work at all, will take me about 150 hours or so.
This make perfect sense if all you are doing is copying a few columns or maybe one or two objects, but I am talking about 600 + objects with upwards of 2 million rows of data in each!!
This generates 2 questions: 1. If the Import Data Wizard cannot handle this operation on the fly, then why can't the AlwaysUseDefaultCodePage property be shown as part of the connection 2. How do I create and SSIS Package that will copy all of the data from Oracle to SQL Server? The source tables have been created and have the same Schema and Object Names as the Source. I don't want to create a Data Flow Task 600 times.
We are using SQL CE 3.5 on tablet PCs, that synchs with our host SQL 2005 Server using Microsoft Synchronization Services. On the tablets, when inserting a record, we get the following error: A duplicate value cannot be inserted into a unique index. [ Table name = refRegTitle,Constraint name = PK_refRegTitle But the only PK on this table is RegTitleID.
The table structure is: [RegTitleID] [int] IDENTITY(1,1) NOT NULL, [RegTitleNumber] [int] NOT NULL, [RegTitleDescription] [varchar](200) NOT NULL, [FacilityTypeID] [int] NOT NULL, [Active] [bit] NOT NULL,
The problem occurs when a Title Number is inserted and a record with that number already exists. There is no unique constraint on Title Number. Has anyone else experienced this?
Is it possible in SQL Server to have replication happen immediately aschanges are made. That is, a change is made on server A, and that change isautomatically applied to server B, rather than the replication happening atset intervals?Thanks.
Hello 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);
// 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.
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.
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?
I have 2 distributed databases which need to be synchronized at regular basis. I plan to write a service that does it. But I'm just curious how to do the update incrementally. Thanks
I have a website that is running on the intranet and on a notebook. I have a notebook that is not always connected to the internet.. when it is not connected, it will read in some data from a barcode reader; and when it's connected, it will synchronize the data with the db on the intranet.. any idea on how to achieve this?
Hi All, 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!!!!!
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.
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 want to create a web application architechture which having multiple web server. this all web server having sql server database. now what i want is to Keep all data in all databases. means i want to synchronize my all sql servers. it is also possible ki my one webserver can have multiple clusted database. hope to hear soon from u people.
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?
Hi, 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
I have one Informix in OpenVMS machine and another MS SQL in Windows machine. I cannot touch the Informix server at all.
How to do the extract/update the data periodically from Informix to SQL? I was thinking of writing a service. But I don't know how to do the incremental update.
I was thinking of doing a pull subscription from MS SQL. Is it feasible? Is it a replication or integration service? I dunno. Please help.
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.
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.
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
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.
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?
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-
