Jan 23, 2006Hi there,
I wonder if I can ask for some advise? I wish to use SQL 2005 and merge replication but I have a few concerns over the schema changes that I am allowed to do on the publisher.
Ideally I want sql replication to push all my schema changes from the publisher to the subscribers but I don't know if it can. or even if it is recommended.
I see the BOL suggesting that schema repl. was mainly intended for ALTER type of statemenets, but can I use it for CREATE and DROP type DDL too?
For example, if I add a new table at the publisher I presume I have to add a new article too for this table. Then how can I create a new snapshot? Is this even the right way of doing it? Similarly if I want to DROP a table at the publisher I'm guessing I have to also delete any existing articles too, then recreate the snapshot.
Are there better / safer ways of doing schema changes? Perhaps I'm best disabling publishing and asking each remote site / db to update their schema manually and then re-enabling the publisher?
Any help would be much appreciated.
Regards.
Merge Replication Between Same Schema Databases But Different Data
Jan 25, 2007Hi all.
I 'm trying to set up merge replication between two servers that have the same schema databases. The two database have the majority of there data the same but as well as data inserted at a later time independently on the two servers. (The two servers were connected in a merge replication scheme that failed at some later time and replication was paused, but users continout to insert data indepentedly at the two servers.)
I need to get them up and running.
I cleaned replication at both servers, I recreated the publication at the puplisher distributor and all is fine.
When I create a push subscription to the subscriper I get the error invalid column name 'rowguidcol' .
I so far managed to have merge replication running on two identical databases (schema and data).
Just some thoughts. After some reading I found that it might be related to identities and identity range or indexes. I set the identity seed and increment at 2, 2 at publisher and at 1,2 at subscriper. (On the same tables at puplisher and subscriber.) Is that ok? is that the way to do it?
Digging a bit more Using the SQL Profiler I can locate the error to happen when sp_MSaddmergetriggers executes.
Thanks allot for any help

Merge Replication Schema Sync Problems
Sep 10, 2007
I am using a merge publication set to synchronize schema changes. Why am I getting the following message when I try to sync after having added columns in the publication database using ALTER TABLE statements?
The schema definition of the destination table ... in the subscription database does not match the schema definition of the source table in the publication database. Reinitialize the subscription without a snapshot after ensuring that the schema definition of the destination table is the same as the source table.
Also, why doesn't reinitializing the subscription with @upload_first = false not fix the problem?
Error In Merge Replication The Schema Script...
Jun 25, 2007I'm trying to set up a merge replication. Publication is created successfully and snapshot also, but when I create pull subscription on subscriber server and merge agent starts, after some time I get an error message of this type:
The schema script '\ANILREPLDATAuncANIL_BEJK_BEJK20070625142735dl_HF_vMSCene_3836.sch' could not be propagated to the subscriber.
It seams there is a problem with certain Views and SPs, because tables are successfully created, and some Views and SPs also.
I tried to exclude problematic articles, but every time another one pops up. Up until now, I excluded 7 articles from publication (1 Stored Procedure and 6 Views) but I still get errors.
I gave up because I can't exclude half of the Views and SPs just to make it work.
Is there something that can be done to solve this problem?
Thanks!
Replication :: Merge Rep Schema Change And Processing Order
Jul 14, 2015Question re Merge rep (pull) and processing order.  We have a group of changes associated with an app upgrade, the scripts run fine on the publisher.   Part of the change includes creation of a new table , followed by altering a view to use new table.Following the change at the publisher, when the sync is kicked off from the subscriber, it fails - the alter of the view throws an'invalid object' error with regard to the new table. Seems as if the view alter is attempted before the dependant table has been created.Â
I have tried to amend the processing order of the view using sp_changearticle, which executes (quickly) with a 0 return code.But it is to no avail , the error still occurs.  is it possible to change the processing order for a view article , which will be applied to schema changes ? Have
How To Handle Schema With Sql Server 2000 Merge Replication
May 29, 2007I have a problem with sql server merge replication in sql server 2000.
If my db owner €œdbo€? and replication setup under €œsa€? account it works with out any problem. But when I use another db owner it can not work properly.

Problem : Extreme Activity - Slow Merge Replication - From A Schema Update
Jul 4, 2007Hi there,
We have a big problem here with merge replication, specifically whenever a schema change occurs. We are replicating schema changes, and triggers/stored procedures. The example is that we changed about 150 stored procedures and about 30 triggers. This is then replicated to the subscriber database (which is also a merge publisher for further remote systems that were offline at the time) over a 10Mb link - hardly low bandwidth. However, the replication process takes about an hour and a half - considering the SQL on the primary server took less than a minute to run this is a big suprise.
We've run a trace to see if we can identitfy what is going on. There seems to be a great number of calls to sp_MSunmarkschemaobject - we are still waiting for a trace to complete to fully analyse this however it looks like it calls this repeatedly for every stored procedure in the database. We are currently re-testing to one of the remote servers with the merge agent set to the slow profile (not much hope that this will alter the poor performance).
This task looks to be excessive - and certainly does not seem to function in a sensible manner. Has anyone else had similar issues or have any suggestions. This is very infuriating as it means that the servers are effectively offline for a minimum of and hour and a half (in fact the remoter servers take over 4 hours !).
Thanks.
Replication: Any Way To Change Table Schema W/o Reinitializing Subscriptions
Mar 23, 2004Hi all,
I'm admitedly a bit new to the world of replication, so please bear with me. I've got two SQL Server 2000 servers running in different locations. Server A does transactional replication over a push subscription to server B. If I need to make a minor change to one of the replicated tables (for example, dropping a no longer used column or changing a varchar field's length) do I need to drop the subscription, make the changes and then re-initialize the schemas and data?
For minor changes, I really hate having to knock out the site runnign off server B while the subscription is re-initialized and data is bulk copied back over. If I want to just make the changes manually on both servers will that cause problems down the line?
Any help is greatly appreciated.

Sep 27, 2007Hi,
I have a table used in Merge Replication. If i add a new column in that table it gives me an error for tables in which either this table is a key or this table has key from other tables "Error validating the default for column 'rowguid'." Also for views i'm getting an error

If i proceed further i get an error and m not able to add the column.
"It is invalid to drop the default constraint on the rowguid column that is used by merge replication.

The transaction ended in the trigger. The batch has been aborted."
Is there any solution for the same?

Cannot Drop A Table On Two Servers After Merge Replication

I tried with success to replicate a table_test_repl from my local server to an other server.
I used only one table for testing.
After that, i can't drop the 2 tables a_test_repl (on my local server and the other : I've got a message 'cannot drop the table because it is published for replication'
What can I do? I need absolutely to drop these tables to keep a clean model

How To Add A Missing Index To A Table In Merge Replication?
Jul 23, 2005One of the table that is in a merge replication somehow is missing anindex. Strangely, only the table in one of the subscriber of the mergereplication is missing the index; another subscriber and the publisherof the merge replication don't have this problem.How should I add the missing index back to that table? My understandingis that making structural change on a table that is inmerge-replication is different from making change on a table that isnot merge-replicated. For example, when we need to add a column into atable that is being merge-replicated, we must add the column bychanging the attributes in the properties of the published article(table) instead of simply using CREATE INDEX command. I am wonderingwhether there is a similar restriction on adding an index onto a tablethat is merge replicated.I have already added the index back to the table anyway. I am askinghere just in case doing this may get me into a problem later on.Thanks in advance for any info.Jay Chan

Problem With Conflict Table For Merge Replication
Sep 3, 2007Hi
I faced with strange problem.
From time to time, during syncronization I get the following errors at the subscriber:
ERROR: -2147200992
SOURCE: Merge Replication Provider
TEXT: The merge process could not store conflict information for article 'Products'. Check the publication properties to determine where conflicts records are stored. When troubleshooting, restart the synchronization with verbose history logging and specify an output file to which to write.
ERROR: 2812
SOURCE: OFF1SQLEXPRESS

ERROR: -2147199481
SOURCE: Merge Replication Provider
TEXT: The Merge Agent was unable to update information about the last synchronization at the Subscriber. Ensure that the subscription exists at the Subscriber, and restart the Merge Agent.
After I refresh the snaphot at the publisher, these errors disappear and the syncronization is completed without any problem. And I can sync easy again week or two..
What is the problem?
What is the right solution?
Yep, I can continue to refresh the snapshot each time when the error appears, but..
maybe there is another approach?
Thanks in advance!

Does The Actual Update Statement Of A Table Affect Merge Replication?
Dec 8, 2006Suppose your using Merge Replication.
2 Users in 2 locations issue updates to the same table. 1 updating 1 column and the other updating another column. Now in reality the actual Stored Procedure issuing the update statement is passed in all the possible columns that could change and builds an update statement that updates all columns even the ones that havent changed.
Will this break Merge Replications conflict tracking? Or does SQL Server 2005 Merge Replication pickup that in reality the 2 updates only in reality changed the values in 2 columns.
Merge Republish Schema Changes
May 4, 2007Hello,
I'm working on a replication topology that is completely merge. We have a single consolidated instance (SQL 2005 SP1 Standard) that holds all data and is a continuous push merge publication filtered by region to regional instances (SQL 2005 SP1 Standard). Then we have individual user instances (SQL Express SP1) that pulls from the republished regional instances which is filtered by user. Both publications have Replicate Schema Changes set to true.
I'm testing out changes to tables and sps on a test system I've been using this process:
1-Run Snapshot on the Consolidated instance
2-Verify all published articles have a status of 2 in sysmergearticles
3-Run Regional Snapshot
4-Verify all published articles have a status of 2 in sysmergearticles
5-Run alter table scripts
6-Once all three levels have the table changes, run the alter sp scripts
I've gotten to step 5 and and the changes get replicated to the regional instance just fine however only the existing column changes get replicated to the SQLExpress instance, not the new columns. Looking at the articles in the regional publication it shows the new columns, but they are not selected. I know I can manually select them (or probably write a script that adds them to the publication although sp_repladdcolumn has been depreciated), but isn't there a way to make this a completely automated process since it's just a republished database? Also is the process I'm using the correct one?
Thank you,

Schema Changes On Merge Publication On SQL2000 And SQL2005
Apr 17, 2007Hello
I've got the following problem: Our product is delivered with SQL2000 and SQL2005.
Now, there are some schema changes, which I'd like to deploy with T-SQL on the publishers. With SQL2000 I do it with the sp_addmergecolumn etc and on SQL 2005 (if replication compatibility level is 90) with replication of DDL. So far so good.
But how can my T-SQL Script determine, wether the replication of DDL is on? I know there exists sp_helpmergepublication, but how do I get the column replicate_ddl of the result-set?
thanks for your advices.

Merge Replication Set Off Transactional Replication
Oct 9, 2007I 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??

Replication And Schema Modifications
Mar 30, 2000SQL Server 7.0 (Service Pack 1 )
A table is currently set up with Transactional Replication. A new field needs to be added to the table. The system needs to continue to be live. What is the best way to handle this kind of situation?
The database model cannot be frozen once replication is in place, and a fresh snapshot cannot be taken each time this occurs since this is very timely on large tables, and errors could occur with other tables replicating since there are foreign key constraint in the Target database.
I haven't been able to find a way to be able to continue replicating the old records which may have been in the log during the addition of the field, as well as the new records with the new field. I must be missing something, since the model must be able to be altered once replication is in place, without the shuting down of the entires system.

Three Level Replication Schema
Nov 24, 2006Hi I have to questionsproblems I would need help with. First I am creating a three level merge replication. I mean I have a main
publisher with its distributor, a subscriber/publisher and also with
it's own distributor and lastly a subscriber.
I start by creating the relation between subscriber/Publisher and the
subscriber and than I move up to the main Publisher and
SubscriberPublisher relation. After this second merge I get the
following errors and the articles in my SubscriberPublisher are
lost...
The merge process could not retrieve article information for
publication 'I-Test-Publisher'.
(Source: Merge Replication Provider (Agent); Error number: -2147201017)

(Source: DEVSERVER3MSDE (Data source); Error number: 21197)
---------------------------------------------------------------------------------------------------------------
Secondly
I have set up a two level merge replication with a publisher and a
subscriber and had modified the structure of a table in the publisher
with sp_repladdcolumn. During the day all was fine I continuously
tested it by adding more columns, droping columns and testing the
replication itself with data entry, but when I got back
the next morning my test table and all other table I presume had lost
its data and structure. The conflict table for the corresponding test
table had kept it's structure but no data were present since no
conflict had occured. This is a recuring problem that some colleagues
had.
Does anyone have any idea what might cause this problem and why it
happenned.
Thanx
