Replication :: Backfill Data After Failed Publications
May 10, 2015
We have setup Transactional Replication that was originally initialized from a backup. Our subscriber recently had some hardware failures causing the publications to fail. We now have the server back up however the transactions for a few days have been missed, and data is now out of sync.
How do I go about resyncing that missing data? We have too many table to manually resync the data, and I cannot restore the database directly from a backup due to some permission issues and differences from the publisher. I've attempted to generate a new snapshot
However I get a message "[0%] A snapshot was not generated because no subscriptions need initialization." My current understanding that is that I should be able to take a snapshot from the publisher and apply it to the subscriber, thus syncing all the data.

I'm trying to set up replication between two servers that both used to have SQL Server 6.5 on them. I was previously getting a 'The ID '114' was not found in the tasks collection' message and so decided to be on the safe side and remove and re-install SQL Server on both machines. Having successfully re-installed SQL Server 6.5 on both machines I then thought I'd try and set-up replication again. BUT as soon as try to install the publishing side of it the only option I have is to uninstall publishing ???? SQL Server on both machines appeared to uninstall and install nicely so how come it's still asking if I want to uninstall publishing ????
Any ideas would make my Xmas.
thanks Paul

Hi, I right click on the publications and hit 'properties' but can't find where the frequency of them is.

Hi.
I have a database with two publications.
One publication is used to replicate data among 4 SQL Servers, while the other is used for the replication with SQL Server CE clients.
The problem here is that the SQLCE receive a number of changes that it is not correct.
Before establishing the publication for SQL Servers the SQL CE clients were working great, but now i have this problem.
Is there any patch or fix I should install on the server?, or do you know how can I solve this?
Thank you.

Hi,
We are using transactional replication with updatable subscriptions in SQL Server 2005. In our case both the publisher and the distributor is the same server. The subscription type is the Pull Subscription. It is set to run in the continuous running mode.
Can we have more than one publication in the same Distributor?
Please refer the link below :
http://msdn2.microsoft.com/en-us/library/ms152471.aspx
This link has a recommendation of the following under the heading "Queued Updating Subscriptions"
"There is only one Queue Reader Agent for each Distributor. It is recommended that for each Distributor, you configure at most one publication that is enabled for queued updating subscriptions."
In our case we need to have 6 publications with 4 subscriptions each (totally 24 Subscriptions).
Pls provide a reply for this asap.
Thanks and Regards,
Swapna.B.

Hi:
Did you have any experience that all publications and their related jobs suddenly disappear?
I had a transactional pull replication between two servers, and distributor and subscriber in the same box; publisher was an AA cluster server.
The schedule of pulling was once a week.
Last Friday morning everything was working perfectly, but I found all publications and their related jobs disappear around 5pm
I checked with the sysadmin and he said nothing was changed on that period.
Did you have any idea about it?
Did you have any idea that I can prevent this happen again or any alert I can set up to monitor who drop it, when it was dropped and so on?
It is a SQL 2000 box and system table doest not take trigger.
Thanks in advance
Theresa

We have many transactional publications, and would like to have identical settings on each of them. Is any way to compare settings of these publications using script?

I am working on a replication design and getting closer to implementation. One of my major concerns is maintaining and updating stored procs and/or user defined functions.
The current design is a single publication, including tables, procs and functions (no views yet). All told there are about 686 articles in the publication. The tables are horizontally partitioned using dynamic filters based on the hostname of the subscriber. There are around 50 subscribers. Most will have small databases (< 250 MB). A few (2-3) will have much larger databases. I am mostly concerned that whenever I have to update a proc or function, I have to re-initialize the subscriptions and that pushes a TON of data out over the network and may interrupt service at the subscriber locations.
I see three options for the procs and functions:
1. Include them in the publication with the data tables
2. Place them in a separate (snapshot only) publication
3. Exclude them entirely from replication and maintain them manually
I am starting to lean towards option #2; but I am a bit concerned about maintaining a duplicate set of replication agents for each subscriber.
Any thoughts and/or comments?
Regards,
hmscott
Am I overlooking something? Is there an option that I have not considered?

Greetings All, I was hoping that a replication sage might be able toanswer a question for me.I want to have one subscriber subscribing to N publishers. Iessentially have a company that has a main headquarters and threesatellite offices. I want each of the satellite offices to push theirdata up to the master database. From what I have read it seems likethis should not be a problem. Some questions that come to mind are:1.)Does the master need to be read only or can it be configured to beupdateable as well?2.)Can the distribution agent on all the publishers be set tocontinuously distribute or should it be staggered so as not to cause aproblem when another distribution agent is running?3.)If the distribution is set to "delay distribution" will this causechanges on the subscriber to be pushed out to the publishers?In this database guid's are used as pk's so the issue of pk collisionsis not a problem.I hope that this question is not too vague. My experience thus farwith replication has been simple one way transactional and simplemerge replication.Regards, Louis Frolio

Hi,
i'm doing POS system by using C# in visual studio 2005. Recently, i installed the microsoft sql server management studio on my pc, i plan to do merge replication through local publications between my pocket pc and my pc. So, i opened the replication file which is under Object Explorer in microsoft sql server management studio, it ONLY show me the local subscription folder under the replication file.Do i install incomplete set of microsoft sql server management studio?Local publications and local subscription, which one is more suitable for POS system?

We need to replicate multiple databases (publications) to one central subscriber. The schema of those articles are identical in all publications and also the primary keys in publications do not have any overlap.
Is this possible?If yes is there any specific thing that I should consider for it's implementation? Should each publication has it's own dedicated distributor or all of them can share one distributor?

I've created a merge replication a few days ago. it works correctly, but today when click synchronize publications, some of then encounter this error :
Data validation failed for one or more articles. When troubleshooting, check the output log files for any errors that may be preventing data from being synchronized properly. Note that when error compensation or delete tracking functionalities are disabled for an article, non-convergence can occur. (Source: MSSQL_REPL, Error number:

I have smilar kind of an issue with replication. I had sucessfully done replication with Sqlce2.0 on sql server 2000. In development machine I had VS 2003, sqlce development tools.
Now I use the same code done in VS 2003 into VS2005, it sucessfully converted the code.
In server machine (win 2003) I installed sql server 2000, sql server 2000 service pack 4, SP4 merge replication components, sql server 2005 mobile server tools and .Net framework 2.0. Created pubication sucessfuly. In this machine I configured IIS as per the web synchronization wizard. Gave anyonymous permissions. Virual direcory is created sucessfully. I tested the server agent in IE http://myservername/aliasname/sqlcesa30.dll.
SQL Server Mobile Server Agent 3.0 is shown
My application opened successfuly in windows mobile 5.0 Pocket PC emulator. When try to sync its dislays error "A request to send data to the computer running IIS is failed, see Hrresult"
No firewall in both development and server machines.
The same code works if its sqlce20 perfectly with vs2003 code. Not in this
Can anyone tell me whats wrong in this?

I'm getting this, after upgrading from 2000 to 2005.Replication-Replication Distribution Subsystem: agent (null) failed.The subscription to publication '(null)' has expired or does notexist.The only suggestions I've seen are to dump all subscriptions. Sincewe have several dozen publications to several servers, is there adecent way to script it all out, if that's the only suggestion?Thanks in advance.

[Source - chn_employee_vew_test_txt [1]] Error: Data conversion failed. The data conversion for column "Column 42" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
[Source - chn_employee_vew_test_txt [1]] Error: The "output column "Column 42" (136)" failed because truncation occurred, and the truncation row disposition on "output column "Column 42" (136)" specifies failure on truncation. A truncation error occurred on the specified object of the specified component.
I using Locale (People's Republic of China) and code page of 936 (Simplied Chinese GBK) with header row delimiter {CR}{LF}.
I am using flat file import method.
Whenever the server process the Column 42 with value "11,Nanjing Rd.W, China" which contain 'comma' or '.' it will hit error importing with above message. When i manually change the column value to non comma or '.' (11 Nanjing Rd W China) in the flat file it is ok.
I am using SQL server 2005.
Please advise what need to be done to avoid this error ?
Thanks in advance and any idea or suggestion is very much appreciated as i have try to solve this issue for over a week but still not able to find any answer on it.
Please help.

Now, I am getting closer and receiving the following message in the Distribution Task (repl_subcriber is the owner, AutoStart is the Frequency):
"37000[Microsoft][ODBC SQL Server Driver][SQL Server] Login failed - User: Reason: Not Associated with a trusted SQL Server connection."
I have 'sqlexecutivent' and 'pswd' defined on the CA (Publisher) and VA (Subscriber) Servers. I have 'sqlexecutivent' defined in the NT Administrator group on both machines. I have trusted the NT Administrator group to SQL Server on both machines (xp_grantlogin 'administrator', 'admin'). I have trusted the NT 'sqlexecutivent' login to SQL Server on both machines (xp_grantlogin 'sqlexecutivent', 'admin'). I have logged-in to both NT machines using the 'sqlexecutivent' login and 'pswd'. I have started the MSSQLServer Service and SQLExecutive Service using 'sqlexecutivent' and 'pswd'. When I set up the Topology, Publication, and Subscription I was registerred in SEM as 'sa'. I do not know if this is needed, but in SQL Server I also created 'sqlexecutive' logins and 'sqlexecutive' database users on both machines.
Please tell me what I am missing. Do I need to do anything with the repl_subscriber and repl_publisher login ids? Do I need to configure a DSN? Do I need to check anything in the registry? Maybe I need to just start over again with a fresh start by uninstalling the Replication Topology, Publishing, etc. Maybe I should try Multi-Protocol.
Again, these are two NT 4.0, SP3 machines running SQL Server 6.5 SP5a. They are set up in the same Workgroup. I can connect to both machines in SEM and by Mapping a Network Drive. The default netlibrary is set to named pipes.
As part of my appreciation for your efforts, I will document this process and mail it to you once it is working.
Thanks, Kevin

I have been attempting to set up replication between two 6.5 servers in the same domain, and all I get is a login failed error on my replication task. Both servers use standard security and an admin login for the server and exec service, and I am using the default remote server setup as installed with replication. I'm sure it will be something simple, but I can't see it.
Thanks in advance for any help you can offer.

Hi All,
We have a SQL server 2000 merge replication and it has been running for couple of years. We were even fine too at the beginning after upgraded our publisher SQL Server 2000 to SQL Server 2005. Now we are starting have problems. I just found there were two files seem to be too big, MSmerge_genhistory.bcp (1,830,287K) and MSmerge_genhistory90.bcp (1,977,746K). I have no idea why these two files are so big.
My questions are:
1. Why these two files? (we do have a mix of SQL Server 2000 MSDE and SQL Server 2005 Express as the subscribers)
2. Can (Should) I clean the MSmerge_genhistory table? How?(sp_mergemetadataretentioncleanup)
3. What could be the impact to all the existing subscribers if I clean this table?
Thank you for your help.

Hi
My first attempt at RMO is to create a job that will generate the SQL scripts necessary to recreate publications on a warm stanby server.
I thought I'd got a grip on the RMO object model, but whenever I call the script method, an empty string is generated.
Can anyone see what I'm doing wrong?
' Create connection to local server
serverConnection = New ServerConnection(".")
Try
' connect to publisher
serverConnection.Connect()
replicationServer = New ReplicationServer(serverConnection)
replicationDatabases = replicationServer.ReplicationDatabases
For Each replicationDatabase In replicationDatabases
If replicationDatabase.HasPublications Then
replicationDatabase.LoadProperties()
Console.WriteLine(replicationDatabase.Script(ScriptOptions.Creation))
End If
Next
Catch ex As Exception
Finally
serverConnection.Disconnect()
End Try

Hi all,
I hope someone who knows how to fix the following problem could shed some light:
I have set up a two-way transactional replication between two SQL 7.0 servers. The updates and inserts on server A is successfully replicated to server B. But when I tried to test if changes on server B is replicated onto server A, I got a 'login failed for user 'sa'' when I modified a user table. It sounds strange because I already logged in using 'sa' and all SQL servers use the same 'sa' login. I wonder if it is a Microsoft bug. The same problem happened on a pair of SQL 2000 Enterprise servers.
Thanks for any input.

Transactional replication running via a pull subscription between a single subscriber and single publisher on Windows 2000 servers (all current service packs and patches) with SQL Server 2000.
Early on Sunday morning, the server hosting the publisher was rebooted...but SQL Server Agent failed to start fully, causing the log reader agent to not start and no alerts to trigger. Still trying to isolate the cause of the problem with SQL Server Agent, as it's been problematic to keep it up and running. For the most part, though, it's coming up properly after restarts of the service or reboots, and starting all agents/functions.
However, the snapshot agent ran a number of times pulling schema and batch copies for the articles in the replicated dataset, and the distribution agent now fails each time it runs with a reference to "not having the initial snapshot for the publication available". SQL Server Agent went down before this could complete, and I left it down until I could ascertain the best route to take...
Any chance I can circumvent having to reapply a initial snapshot of the publication db (this is a large set of data), and just apply transactions from the log since my downtime has only been about 60 hours? Or is there an agent setting, job run to reinitialize, or an inherent quality to SQL Server Agent that will demand a complete reapplication of the snapshots due to the down time?
I'm betting that the distribution agent will start moving data as soon as the snapshot agent finishes up (as I said, it has not completed yet), but I'm praying there's a way to get around this...
Thanks!

What are the different options for setting up Alerts when Replication stops or errors out?
I ran this code on the publisher:
USE [msdb]
GO
/****** Object: Alert [Replication: agent failure] Script Date: 10/2/2015 11:42:46 AM ******/
EXEC msdb.dbo.sp_add_alert @name=N'Replication: agent failure',
@message_id=14151,
@severity=0,
@enabled=0,
[Code] ....
It already existed.
So I ran it on the Subscriber and it executed.
Are there any third party tools to do this?

Every time i get different error messages..recently i get message of 'Subscriber failed to initialize'. Could anyone suggest how to resolve this? Urgent please.

I just applied instcat.sql to my SQL Srvr 2k sp4. At first it broke my replication with some cursor errors. Applying the latest instcat.sql fixed the problem, however one of the distribution agents would not start (i'm not sure if instcat had anything to do with it) giving me a "Login failed for user 'NT AUTHORITYANONYMOUS LOGON'. The process could not connect to distributor 'DistributorName'. The step failed." error.
Any suggestions would be greatly appreciated!
