Password Expiry With HTTPS Merge Replication
Feb 13, 2006
Hi
We are using anonymous HTTPS merge replication.
The windows password used for the client subscriber expired on the publisher.
I reset it on the publisher - but SQL still seems to think that it is not expired - I get the following message in the event log of the publisher running SQL Server 2005
Login failed for user 'XYZ'. Reason: The password of the account has expired. [CLIENT: <local machine>]
Any ideas ?
thanks
Bruce

How to check if web merge sync is working between a subscriber and publisher thru HTTPS ? SQL port 1433 at subscriber is blocked so no direct connection to subscriber.

Hi. I've looked all over MSDN, newsgroups and the web but I can't find the answer to a problem that I am having.
The application that I am working on used both transactional and merge replication. I want to avoid hard coding passwords into an application that kicks off the pull replication on the client machine.
The client machines are all using SQL Server 2005 Express. The other machine is running SQL Server Standard. The passwords and login details are specified in the subscription properties in the Management Studio.
A fragment of the code is posted below. The transactional sychronization works fine without having to specify any passwords - however the merge replication does not work if both of the passwords are not specified.
private void SynchButton_Click(object sender, EventArgs e) { // Set up the subscriber connection details. subscriberConnection = new ServerConnection(subscriberName); try { // Connect to the Subscriber. subscriberConnection.Connect(); // Do the transactional subscription synchronisation independantly of the // merge subscription replication. try { transPullSubscription = new TransPullSubscription(subscriptionDbName, publisherName, publicationDbName, transPublicationName, subscriberConnection); // If the pull subscription and the job exists, start the agent job. if (transPullSubscription.LoadProperties() && transPullSubscription.AgentJobId != null) { TransSynchronizationAgent transSyncAgent = transPullSubscription.SynchronizationAgent; transSyncAgent.Synchronize(); } else { } } catch (Exception ex) { } // Do the merge subscription synchronisation independantly of the // transactional subscription replication. try { // Set up the subscription details for the merge subscription (bi-directional data) mergePullSubscription = new MergePullSubscription(subscriptionDbName, publisherName, publicationDbName, mergePublicationName, subscriberConnection); // If the pull subscription and the job exists, start the agent job. if (mergePullSubscription.LoadProperties() && mergePullSubscription.AgentJobId != null) { MergeSynchronizationAgent mergeSyncAgent = mergePullSubscription.SynchronizationAgent; mergeSyncAgent.DistributorPassword = "<<password>>"; mergeSyncAgent.PublisherPassword = "<<password>>"; mergeSyncAgent.Synchronize(); }etc etc..
Any help or suggestions will be greatly appeciated. Thanks.

Hi
We have about 70 clients, each with their own databases synching to a copy of their database on a remote webserver. They synchronise using a Windows Service which we wrote using RMO.
For completeness, our setup is as follows:
subscription.CreateSyncAgentByDefault = False -- I wrote a windows service to synchronise
subscription.UseWebSynchronization = True
subscription.InternetSecurityMode = AuthenticationMethod.BasicAuthentication
subscription.SubscriberType = MergeSubscriberType.Anonymous
Sometimes, one of our clients synchronisation goes up the spout - it might take hours to synchronise - despite their internet connection being fine. And once this starts to happen, nothing will fix it. We've restarted their server, rebooted their router etc etc.
Well, the only way of fixing it is to recreate the publication, copy the backup, reinitialise and start again, which costs us a days work and inconveniences the client greatly.
What would be the likely trigger for this. How can we stop this happening again.
If it helps we could create a trace to help resolve this.....
Regards
Bruce

Hi

subscription.UseWebSynchronization = True
subscription.InternetSecurityMode = AuthenticationMethod.BasicAuthentication
subscription.SubscriberType = MergeSubscriberType.Anonymous
Some of our subscribers have low-quality internet connections - how do I get the agent at the publisher/distributer use a slower profile - I've read How to: Work with Replication Agent Profiles (Replication Transact-SQL Programming)
but can't see where you specifiy an alternate agent profile
On the distributer / publisher (same machine) I go to replication monitor -> Warnings and Agents - I can only set the profile for the snapshot agent....
thanks

Hi 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).

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...

I have a server that I will need to uninstall SQL Server and then install it again because of missing files.
I need to bring the back to the way it is or was. My problem is replication.
Since I am new one knows the Administrative Link password. When I try to generate script for replication for the password it uses the 'N'.
Is there a way to work around this problem? Please advise.
Thanks

We are currently using continuous transactional replication from an OLTP type database to a Reporting database. We recently changed the 'sa' password for the first time since replication was introduced and now the Replication Log Reader job fails to start.
This is the error from the Job Log:

2008-04-14 15:18:25.034 Login failed for user 'sa'.
When we change the 'sa' password back to the previous value, we can start the Log Reader without issue.
We have tried restarting the SQL Server Agent process without success. We have not restarted the SQL Server process due to the server hosting production databases.
Any ideas?

I have a publisher, distributor and subscribed in transactional replication topology, each on a different MS Windows 2008 server. SQL server version is 2008. I changed the password of the service account used to the the sql server and sql server agent services on all 3 servers. But now replication stopped working (Distributor to publishers shows errors in replication monitor for all publications).
I restarted the services and also tried restarting the servers. I did "update replication passwords" and also used sp_changereplicationserverpasswords to change replication passwords. But it doesn't seem to work.
From [MSrepl_errors], i get the below errors:
The process could not connect to Subscriber 'XXX'.
Cannot generate SSPI context
SQL Server Network Interfaces: The target principal name is incorrect.

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!

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.

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 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
