Do Not Replicate DELETE Statements Still Replicates Deletes To Subscribers
Dec 4, 2006I previously asked What does "Do not replicate DELETE statements" do? to make sure I was correct on my thinking of what "Do not replicate DELETE statements" does. And after finding out it does what I would like it to do, create an archive db, I've tried several testing scenarios to see if it would work. So far I have been unable to not replicate delete statements. I'm not sure if I'm not setting a property right or what and any guidance would be appreciated.
Here is what I've done.
Created a blank db to be used as a subscriber and created a test db with some random data in a table.
Setup a New Publication on the db with the random data as "Transactional Publication"
Selected the following articles and properties in the publication
Tables
DELETE Delivery Format = Do not replicate DELETE statements
Views
Default Values
Stored Procedures
Default Values
User Functions
Default Values
Selected the default options for the rest of the New Publication Wizard steps and clicked finish.
Created a Pull Subscription on the new publication that I just created.
Let it initialize.
Then did a select count(*) query on the test table on the publication (18k+ rows) and subscriber (18k+ rows)
Then did a delete t-sql from the test table on the publication.
Then did a select count(*) query on the test table on the publication (0 rows) and subscriber (0 rows).
Now shouldn't it not delete the records on the subscription db?
Replication :: Replicate Multiple Databases (publications) To One Central Subscriber?
Sep 2, 2015We 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?
Replication :: One Publisher 2 Subscribers
Nov 9, 2015Is it possible to replicate data from one publishers to a multiple subscribers in transaction replication? In other words I have Server A, Server B, Server C with databases A,B,C respectively. I need to replicate 10 articles from A to B but only 1 from A to C. In other words I want to use the same publisher but select one article from that publisher instead of all 10 to Server C/database C.
If it is possible what will be the drawbacks of such implementation? Will performance be a hit?
No. Of Subscribers In Transactional Replication...
Jan 25, 2007Hi,
I am Using Transactional Replication with Updatable Subscriptions. Is there any limitations in the number of subscribers (Servers) used for this type of replication?
I have a scenario of configuring this replication in 60 Subscribers(Servers). And the replication should be in the Continuous running mode. Will Transactional Replication with Updatable Subscriptions work in this scenario??? Or is it meant to work for less than 10 subscribers?
Please reply asap.
Thanks in advance.

Maximum Number Of Subscribers And Transacational Replication.
Sep 21, 2006Hi:
Is there a limit on the number of subscribers for Transactional replication?. My question is how many maximum number of subscribers can we have in transactional replication?. How do I retrieve this information throug T-SQL (any DMVs or system tables?). Please let me know.
I am looking to know for both SQL 2005 as well as SQL 2000 and also if anyone can tell me if anything has changed in SQL 2005 for transactional replication that would be great.
Can anyone please let me know?.
Thank you

SQL 2005 Replication Performance: More Than 3000 Subscribers
Jun 7, 2007Hi All,
We are developing a system which will have to support more than 3000
subscribers. We will have to support both Transactional replication
and Merge replication.
I checked the following document about SQL 2005 replication <http://
www.microsoft.com/technet/prodtechnol/sql/2005/mergrepl.mspx>. The
document does not clearly specify what is the maximum number of
subscribers supported without a significant performance degradation.
The questions i have are:
1. Given the fact that there will be more than 3000 subscribers, there
will be more than 500-1000 subscribers trying to replicate at the same
time. Will be there be a performance degradtion in such a scenario
2. Has anyone used SQL Server 2005 in a scenario involving more than
3000 subscribers?
3. Will it be better if we develop our own system to perform
replication activity instead of relying on SQL Server 2005?

Delivering The Same Report To Multiple Subscribers
Feb 7, 2008I am trying to figure out some scalability-related requirements for the project I'm working on, and unfortunately I cannot find out an answer to one of the questions by test-running, so I have to ask it in hope that someone has a definitive answer.
When two - or, more - different (distinct) users/subscribers
running the Report Manager from two different machines
[independently of each other] create their two subscriptions
with almost exactly the same parameters (same report name, same report rendering format, to be delivered via email at 6:00 AM every day, etc.),
and the only difference between those subscriptions is in email addresses (to whom the report shall be delivered)...
... when those subscriptions get executed at 6:00 AM,
are they executed only once (because those 2 subscriptions are the same except by whom they were created and to whom they should be delivered),
OR
is each of them executed separately?
In other words, if multiple users create absolutely the same subscriptions (except for a parameter to whom they should be delivered), how many times does the Report Server run that report?
Thank you very much.
How To Create Merge Replication With Latest Update Always From Subscribers
May 13, 2006Hi ,
I am trying to create Replication Topology (Merge Replication) like below.
Subscriber1 --> Publisher <-- Subscriber2.
I have created both subscribers with Subscription Type as Server with Priority as 75. I am updating the Column A of Row_10 in Subscriber1 on time say 11 am. After i am running the Starting synchronizing agent from Subscriber1. The value propagated to Publisher now publisher contains the latest value in Column A. Uptonow the Subscriber2 is not synchronized with Publisher.
Now in Subscriber2 also Column A of Row_10 is updated say at 11.10 am. Actually now Publisher contains the value from Subscriber1 for that Column and in Subscriber2 we have the same column updated.
Now i am running the Synchronization in Subscriber2, i am getting the result which is not expected. Here Publisher's value is propagated to Subscriber2. But as per real scenario Subscriber2 has the Latest value which is updated on 11.10 AM.
I don't know what am i missing here. Actually merge replication should see the time stamp and it has to decide winner. But here it always considers publisher as a winner and puts the data to Subscriber.
Can anyone help ?
Thanks in advance
Merge Replication With Anonymous Subscribers And Identity Columns

I read the BOL on how the publisher will had out identity ranges to subscribers, but it was not clear if this was also the case for anonymous subscribers. Will merge replication with identity columns work with anonymous subscribers that sync via HTTPS?

Optimising Merge Replication For Both Server And Client Subscribers
Jan 4, 2007
I need to merge replicate data to two different types of subscribers:
Clients subscribers which will have a very small percentage of the data from the central database. The data on these machines will be managed using dynamic filtering on host_name()
Server subscribers which will manage a copy of all the data from the central database
There will be far fewer server subscribers than client subscribers.
As I see it I have two options for the configuration
1) Use two separate merge publications €“ one which is filtered and one which isn€™t
2) Use a single merge publication and setup the filtering so that the server subscribers receive all the rows
Which option is likely to lead to better performance?
With option 1) there would be 2 complete sets of replication metadata which need to be maintained €“ so I am tending towards option 2. Are there any disadvantages in using a dynamic filter to return a very large number of rows?
Transactional Replication - Updatable Subscribers - Image Data Type- Sql Server 2000
Aug 21, 2007Sql Server 2000
I am looking for bidirectional transactional replication using updatable subscribers (queued or immediate) . Is it possible to replicate the image data from the updatable subscribers to the publisher. I understood that the Image data can't be replicated to the publisher from the updatable subscriber. I am not using the WRITETEXT or UPDATETEXT. I am using just INSERT and UPDATE for image data type transactions.
Any thoughts on this is greatly appreciated.
Thanks in advance
Is 2005 Merge Replication Reliable For Compact Edition Subscribers On WinXP Tablets Over VPN?
Oct 24, 2007
I posted a more detailed technical question a couple of weeks ago
with Subject = "Compact Edition 2005 Subscribers - Merge Agent failed after detecting that retention-based cleanup has deleted metadata"
But I got no replies.
Now my question is simpler: Is SQL Server 2005 Merge Replication reliable with Compact Edition subscribers on WindowsXP tablets?
We deleted all users' local databases a couple of weeks ago, and republished two publications with retention = 60 days.
Now we have at least one user who can't sync with the server, and replication monitor shows the error below.
But if she e-mails her sdf file to a support person, they can successfully sync her database.
We're sure that it's not a permissions issue, which is a normal suspicion when one user can perform a task that another can not.
It doesn't seem like a retention problem, because she's well inside the retention period.
She can successfully sync with the publication with upload/download tablers, but not with the publication with download only tables. Both publications were created on the same day, by the same DBA, with nearly identical properties.
This problem user has operated in the past with no problem, and she's configured identically to all of the others. It just seems like random flakyness with merge replication for Compact Edition subscribers.
I feel stupid saying that, because it sounds like I believe in a magical ghost in the machine. So my question is - IS MERGE REPLICATION A LITTLE BIT FLAKY FOR COMPACT EDITION SUBSCRIBERS ON XP MACHINES?
We've applied SP2 to the server, but no subsequent HotFixes.
We're trying to sell users and management on developing a larger occasionally connected system with the same replication scheme, so we need to know if it deserves our confidence.
Error messages:
The Merge Agent failed after detecting that retention-based metadata cleanup has deleted metadata at the Publisher for changes not yet sent to the Subscriber. You must reinitialize the subscription (without upload). (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147199402)

Replication Doesn't Replicate
Jul 8, 2004Ok, I'm knee-deep in replication-hell.
I'm trying to set up snapshot replication between two SQL Server 2000 databases over the internet. Both servers run Windows 2000 server edition and SQL server 2000. The idea is to send certain local information, stored in database tables to a database from which the information is published on a website.
I've set up the distribution database (with the original name: distribution) and connected a publisher to it (let's call that one "source_database") using the sp_adddistpublisher stored procedure. No problems there...
Next step, I added a publication, the tables in source_database, and a subscriber, the website database. I've opened up port 1433 on both servers, but still it won't send anything from the source_database to the website database....
It gives no errors, but just doesn't do anything...
Now, I've looked for possible problems and I think these problems might be able to cause problems:
- The initial snapshot is not reaching the subscriber
- I've made a push subscription which may has to become a pull subscription
- The RPC's aren't available, because both servers are highly secured
- The wrong serverpack is installed (this one is a wild guess)
Does anybody have any idea on how I can get my distribution working or solve any of the problems above, cause I'm running out of idea's....
(P.S. I'm a bit of a noobie to replication, I've set it up in a test environment before and it just worked perfectly, but the real thing isn't)

SS2005 Replication: Can You Replicate Constraints Without Reinitializing?
Jan 11, 2007We have a two SQL Server 2005 databases set up using Transactional Replication. My manager has asked me to set it up to replicate constraints (default, fk, et) on the tables in the main publication. I said sure, I can do it, but I will have to re-initialize the subscription. He said there was a way to do it without re-initializing the subscription. I cannot find anything in my research to indicate that there is a method to do so (via call sp_ functions, etc). Is it indeed possible to replicate constraints on replicated tables without re-initializing the who subscription? The reason he does not want me to perform a re-initialization is that we are a few weeks before moving into production, and a full re-initialization takes 1.5 days, which would impact system availability.
Thanks in advance for any advice.
Replication :: Unable To Replicate A View Or Function
Nov 13, 2015I have some issue when replicating a view (transactional replication).I have following objects on publisher:
Table: [Metadataschema].[Entity]
View: [dbo].[EntityLogicalView]
the view definition is:
create view [dbo].[EntityLogicalView] as (SELECT * FROM [Entity] WHERE OverwriteTime = 0)
this is what I get when I run "Script View as Create". The same query is used by the replication.Unfortunately this query fails on the subscriber "Unable to replicate a view or function because the referenced objects or columns are not present on the Subscriber". I cannot even runt his query manually on the subscriber, it only works when I change it like this:create view [dbo].[EntityLogicalView] as (SELECT * FROM [Metadataschema].[Entity] WHERE OverwriteTime = 0) Is there any way to get this working? Can I change the creation scripts used by the replication or force publisher to include schema names in all objects?
Transactional Replication Setup To Replicate Views
Mar 20, 2007Hello,
I setup the transactional replication to replicate remote database that has 50 tables.
Two of the tables with huge columns.
I splitted the columns by creating several views before running the initial snapshot.
Questions:
1. Can the database replication copy the views.?
2. Where the view will be stored at the subscriber database?
Thank you.

Replication :: Replicate Value Of A Computed Column Not The Formula
Jun 16, 2015I'm trying to replicate client data from multiple databases into a single table. So database A, B and C replicate client data to a table in database Z. There is a settings table on A, B and C that holds the businessID and I use a function in a computed column to add this to the client table. At the moment I have just database A and Z as a test and what happens is the computed column gets replicated as a computed column with the formula.Â
Can I change this so that I can replicate the computed value (at db A,B,C) of this column?
I don't really want to add a businessID to the table if possible as I'm going to need to add a number of other tables to this replication which will each need to have the businessID, a computed column would be much easier and save updating a load of scripts.
If the above is not possible is there some other solution available so I can identify which database the records came from in the table on database Z?

i have a problem with my replication.
I have two SQL 2005 SP2 Server and want to use the transaction replication with updateable subscriber. Now the problem is that i can do any changes on the master server. But if i want to change a record on the subscriber which contains a ntext, text, oder image column - then i geht the error that the field will be NULL on the master.
Is there any solution to fix this problem? I dont wan`t to change the datatype vom ntext to varchar(max) !!

Replicate To Other Server If Replication With Main Server Failed ...

Let say I've 4 server with MS SQL 2000 installed and I want all of them having the same data. So I'm using merge replication by assign one of them as publisher/distributor.
The problem is when ( let say ) server that have been assign as publisher/distributor down then all the other server cannot make replication.
My idea was to make it replicate to other available server ( among them ) if replication to main server failed.
Is it possible ?
If possible how to do it ?

Setting Up Alerts For Replication
Aug 15, 2012We have occasional problems with transactional replication between 2 databases, and the problem is we dont notice right away. Usually the customer notices a few days after replication has stopped, and thats no good. We want to be notified as soon as there is any problem related to replication so we can go in and figure it out.
Ive been playing with the alerts, and it LOOKS like I should be able to do what I want, but after several hours I still cannot make any of the alerts work.
In my test environment, I'm forcing the following error, in order to try and test an alert: error 20598 "The row was not found at the Subscriber when applying the replicated command."
This seems to be one of our more common errors, and also its really easy to produce, so it seemed like a good candidate for testing the alert.
First off, I noticed that the agent profile was set to "Continue on data consistancy errors", which ignores error 20598. So I changed the profile to "Default", which doesnt skip any errors.
Next I set up a simple Job that simply writes a string to a file. I tested the job by calling it manually and it works. Once i can prove that this job is actually being called, I will change it to email me and the team.
Then I created a new alert in the publisher database which watches for error code 20598. Its response is to call the job I mentioned above. So when the error occurs, a string should be written to that file.
Then I forced the 20598 error to occur. I deleted a row in the subscriber DB, and then changed the corresponding row in the publisher. This causes the error to occur. In my replication monitor, I see new entries saying "Skipped 1 error(s) when applying transactions at the Subscriber." I'm not sure why it says skipped, but I know that these entries are the 20598 error that I'm trying to produce.
Now, there was nothing written to my text file, and I can see from the job history that my job was never called. If I look at the history of my test alert, it says "never occured".
I forced the 20598 error to occur, and I have an alert that is watching for the 20598 error, but it never fires.
I also created an alert in the subscriber database, watching for the same error. This alert was not called either.

I have a WM5 device with Sql Server CE 3.0 and Sql Server 2005 on the serverside. I set up RDA and it works fine until I try do pull a little more advanced query. Instead of pulling a simple table with where clause I created a query that joined two tables returning values from only one. It doesn't seem to be possible, is it? If it's not, is it someway I work around this?
