Replication: Transactional: Multi Publications, One Subscriber.
Jul 20, 2005
Greetings All, I was hoping that a replication sage might be able to
answer a question for me.
I want to have one subscriber subscribing to N publishers. I
essentially have a company that has a main headquarters and three
satellite offices. I want each of the satellite offices to push their
data up to the master database. From what I have read it seems like
this 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 be
updateable as well?
2.)Can the distribution agent on all the publishers be set to
continuously distribute or should it be staggered so as not to cause a
problem when another distribution agent is running?
3.)If the distribution is set to "delay distribution" will this cause
changes 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 collisions
is not a problem.
I hope that this question is not too vague. My experience thus far
with replication has been simple one way transactional and simple
merge replication.

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.

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?

Hi,
I am trying to setup bi-directional transactional replication between 2 SQL Servers,
I add the subscription on both the servers using the code below.
EXEC sp_addsubscription @publication = N'test',
@article = N'all', @subscriber = 'AnyServer',
@destination_db = N'test', @sync_type = N'none',
@status = N'active', @update_mode = N'read only',
@loopback_detection = 'true'
GO
I have defined 'AnyServer' on both the servers using cliconfg
(Server1's AnyServer pointed towards Server2 and Server2's AnyServer pointed towards Server1, I need to do that because there is a restriction to run the same code on both the servers),
After inserting a record on server1 in the 'test' database, the changes successfully transfers to the server2, then server2 sends it back to server1 and server1 generates the error of
"Violation of PRIMARY KEY constraint 'PK_Table1'. Cannot insert duplicate key in object 'Table1'."
It seems as if loop detection is failing if I keep the same subscriber name on both sides.
It runs fine when I change the subscriber name in the subscription (@subscriber = 'Server2' for server1 and @subscriber = 'Server1' for server2).
Can anybody explains this behavior to me?

Hi,
I am trying to setup mirrored subcriber in Transactional Replication in SQL 2005. I am not able to do so as it don't work after failover.However I am able to setup mirrored publisher with distribution property "PublisherFailoverPartner" for snapshot and log reader agent profiles and it works even after failover.
However I need to know, do we have something called "Subscriberfailoverproperty" or any other method to set up mirrored subscriber in Transactional Replication in SQL 2005.
Thanks

Hi!
The distributor was down for a long time (neer the week) and after that the commands stop applying to subscriber, while they successfully collected from publisher and stored into distributor.
Replication agent on distributor reports that initial snapshot is not available. It seems subscription is expired. But all commands from the point distributor down I have. How can I make distr agent to resume activity without reinitialize snapshot?

Hi
I need to setup transactional replication for a production server.
The tables (articles) at publisher being replicated can expect schema changes.
Is there any way to reflect schema changes at subscriber using transactional replication.
Early Thanks,

Any experience of success or failure setting up CDC on the subscriber end of transactional replication?
Also for a bonus answer, why are explicit index operations not permitted (I'm assuming this is even on the publisher?) From BOL:
• Explicitly adding, dropping, or altering indexes is not supported. Indexes created implicitly for constraints (such as a primary key constraint) are supported.

I have taken over a transactional replication setup that is being usedfor fault tolerance (I know, I know...).The scenario I am concerned with is where the publisher goes down due tofailure, so we need to point our application at the subscriber and startupdating the data there. We are not using the immediate updating option.How do I go about re-syncing the publisher with the data that been addedto, or changed on the subscriber, when the publisher comes back online?Thanks,TGru*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

I have a primary and secondary servers both running Windows 2000 SP3 with SQL 2000 SP3. I have set up transactional replication with the primary server as publisher and the secondary server has the distributor and subscriber DB. I am testing the scenerio where my primary server goes down and I have to make updates to the secondary server until my primary server comes back up. I am able to update my subscriber database and the transactions go into the MSreplication_queue table to be pushed back to the primary when it comes back up. When I bring the primary server back up and start the queue agent job it starts pushing the transactions over and then stops after 4 or 5 transactions with the error "Failed while applying queued message to publisher". I have attached part of the log file for the agent below

We have a database which is (a subset of tables are) replicated to another via transactional replication. Whilst most changes made at the published database reach the subscriber within a matter of seconds, we have a SQL Agent job which performs a calculation in the published database and then immediately exports data from the subscriber using log shipping. The result is that the calculated changes do not make it through to the exported transaction logs in time.
Is there a way to manually "refresh" the subscriber databases using T-SQL?

I have a transactional replication environment that creates subscribers on another server as a staging area for an ETL process to a data warehouse application on a 3rd server which is the report repository. Currently the ETL process runs every 10 minutes and performs it's function across approx 150+ subscriber databases and consolidates it to the data warehouse.
I have an SLA of 2 minutes. I'd like to rework the ETL process (which run as SSIS job at the moment) to be specific to a single database and fire that one ETL proces when changes have been applied to that subscriber database only. Of these 150+ databases generally only about 8-10 are updating the subscriber at any given time per Repl Monitor. I'm thinking that if I only have a few transactions to apply to a single db the ETL would run in seconds dynamically as the subscriber is update.
The issue is how to fire the ETL process upon completion of updates to the subscriber DB? I'm thinking of using SP_Start_job passing the DBID to update the warehouse but unsure whether this is possible but if so where to trigger it.

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 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:
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

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?

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." Â 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.

Hello,
I'm interested in combining the Peer-to-Peer Transactional Replication and Standard Transactional Replication to provide a scale out solution of SQL Server 2005. The condition is as follows:
We may have 10 SQL Server 2005 (1 Publisher + 9 Subscriber) running transactional replication in the production environment and allow updates in subscribers. To offload the loading of the publisher, we plan to have 2 Publisher (PubNode1 and PubNode2) using Peer-to-Peer Transaction Replication and the rest 8 subscribers will be divided into 2 groups. The subscribers 1-4 (SubNode1, SubNode2, SubNode3, and SubNode4) will be set to be standard transactional replication subscribers of PubNode1, and the rest 4 subscribers (SubNode5, ..., SubNode8) will be set to be standard transactional replication subscribers of PubNode2.
Is it possible to setup above 2 Publisher + 8 Subscriber topology?
Also, could we set the 8 subscribers with updatable subscriptions to achieve each node is updatable?
We do not plan to set all the 10 nodes using Peer-to-Peer Transactional Replication as it is necessary to make sure n*(n-1)/2 (i.e. 45) peer-to-peer connections is reliable. It seems that the maintenance cost is high if the servers are not in a LAN and the topology is very high coupling. So we prefer to divide the 10 nodes into 2 groups and reduce the cost of each node to maintain the connections to all other sites.
That's the scenario.
Any feedback is welcome and appreciated.
Thanks,
Terence

Hi,I have transactional replication set up on on of our MS SQL 2000 (SP4)Std Edition database serverBecause of an unfortunate scenario, I had to restore one of thepublication databases. I scripted the replication module and droppedthe publication first. Then did a full restore.When I try to set up the replication thru the script, it created thepublication with the following error messageServer: Msg 2714, Level 16, State 5, Procedure SYNC_FCR ToGPRPTS_GL00100, Line 1There is already an object named 'SYNC_FCR To GPRPTS_GL00100' in thedatabase.It seems the previous replication has set up these system viewsSYNC_FCR To GPRPTS_GL00100. And I have tried dropping the replicationmodule again to see if it drops the views but it didn't.The replication fails with some wired error & complains about thisviews when I try to run the synch..I even tried running the sp_removedbreplication to drop thereplication module, but the views do not seem to disappear.My question is how do I remove these system views or how do I make thereplication work without using these views or create new views.. Whyis this creating those system views in the first place?I would appreciate if anyone can help me fix this issue. Please feelfree to let me know if any additional information or scripts needed.Thanks in advance..Regards,Aravin Rajendra.

I have been researching on the proper steps or sequence to follow to completely remove SQL Server 2012 Transactional Replication. Â I have read articles about using SSMS as well as using replication stored procedures and some procedures use SQLCMD or just regular TSQL executed in SSMS. Â I have also read articles where people said all you really need is connect to the Publisher instance, find the publication you want to remove and choose "Delete" and everything will be taken care of behind the scene. I have three SQL servers that participate in transactional replication. Â SQL-P (publisher),Â
SQL-D (distributor) and SQL-S (subscriber). Â Do I need to connect to the distributor instance and the subscriber instance when removing transactional replication or is it just really connecting to the publisher and click delete on the publication? I want everything gone including any metadata, systems tables, distributions db and any other replication objects created during the initial configuration.

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...

SQL Server 7.0 SP3
I am using the "Pull Subscription Wizard" to set up merge replication. I go through all the steps of the wizard and then I hit "Finish" at the end. When it gets to the third step (Creating the Subscription), I get the old:
__________________________________________________ _________
mmc.exe has generated errors and will by closed by Windows.
You will need to restart the program.
An error log is being created.
__________________________________________________ _________
This happens whether I try to do this from my PC or from the actual server I am creating the subscription on.
Has anyone else had this issue? Is there a hotfix I need?
Any help is appreciated.

Hi all!
I hope anyone here can help me with this tough problem:
I have a replication enviroment with several subscribers.
Publisher:MSSQL 2000, SP3
Subscribers: MSSQL200, SP3 and MSDE2000, SP3
Since a few weeks, one of the subscribers fails when
synchronizing with the message
"This process could not enumerate changes at the subscriber"
The erroroutput with verboselevel 3 doesn't help me much, I
append it to the end of this posting. (unfortunately german)
I heard that this error can be caused by a "blank" in an image
column or different Service Pack Versions - definitely not
possible in this case!
The only strange detail is that the SQL Server Versionnumber
of this MSDE shown via EM is not the same as the number shown
in controlpanel->software. By the way, is it ok that here are
two lines for the MSDE?
SP3 is definitely installed on all machines!
Any help would be greatly appreciated - i'm already losing hope...

:confused:
I want to call a stored procedure to do the insert into my published arcticle/table. Is this possible? I know you can call a stored procedure to insert into the subscriber arctiles.
The problem is the published database has a generated primary key (max +1 )that is calculated via a stored procedure during all inserts. I would bring the stored procedure over to the subscriber but that would not help since the values in the target table will not be 'current' because the subscriber database is only updated nightly.
Thoughts?

Hi Guys,
I have tried backing up the replication from Primary Server (Publisher) A and copying over to Subscriber B. When I sync. I am missing the data. I don't know what step I am missing or it is bug on SQL 2K SP3.
I don't know what i am doing wrong.
Can anybody give me a step by step detail how to backup the publisher database and copy to a subscriber and sync by saying the schema and data already available. As we have WAN problem all the times, and when I try the full snapshot of 20 gig it was taking more than 24 hrs and also if the connection fails my snapshot also fails
Please help.
Thanks in Advance,
-Anu
