Hi:
If I create a merge replication snapshot for database A today and I subscribe to the servers on Monday, will the changes made to database A from the time I created the snapshot be applied to the other servers once i subscribe to them
Thanks, Jay
What is the main difference between snapshot and transactional and merge replication?
View 5 Replies View RelatedI'm trying to test merge replication, but am unable to create the publication, the snapshot agent keeps failing. The error I get from replication monitor is "Script failed for Table <tablename>"
Our database has quite a few XML datatype columns, when I take out the xml columns the snapshot succeeds OK, but fails with the xml column.
I created a simple table containing a varchar column and xml column. I created this table in our database, and in Adventure Works. Was able to create a publication with this test table in the adventureworks database, but was unable to create publication with this table in our database. The snapshot failed with error "Script failed for table testtable". I removed the xml column on the test table in our database and was able to create the publication successfully. Creating a publication in the adventureworks database with an xml column has no problems, but does in our database.
Anyone have any ideas?
I was reading at the following page:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnsql2k/html/sql_replmergepartitioned.asp
When SQL Server accesses the data in a table, it locks the data for the duration of the process to ensure the transactional consistency of the data during the process.
I was wondering if it is possible to take advantage of snapshot isolation to allow me to avoid these locks?
At present our snaopshot folder for merge replication(mainly) and our snapshot replications are on a seperate server. We now need to move the folder to a new server.
Anybody explain how we will do this and what affects it will have
Thanks
I'm having issues setting up merge replication and the errors I'm getting are inconsistent but lead me to believe there is a bigger underlying issue than what they actually indicate.
Issue: unable to initialise subscriber with snapshot for merge replication. Fails for various reasons regardless of environment and setup. Previously this has deployed fine but now it is not.
Publisher is SQL 2005 (9.0.2047), Subscribers are SQLExpress or SQL Dev
The various errors I get are as follows:
These come mixed together generally...
Unable to INSERT ... cannot insert NULL into column rowguid. [This error comes up on different tables for different snapshots, including ones with no records]
bcp (Bulk Copy) error 20253
batch send failed
Unspecified error
Failed to send batch after max errors
end of file reached, terminator missing or field data incomplete
Actions I have taken so far, all to no effect:
Adjusted Agent Profile to increase timeout values and decrease packet sizes
Took new snapshots (tables where errors occured changed but still ame errors)
Created a local subscription database on the server to remove any network related issues (using merge sync over VPN)
Deleted and recreated Publication
Created second publication with different articles on same database to find same errors in different locations again
I've tried reinitializing subscriptions (before subscribers were dropped and I tried recreating) but the DROP command fails due to FK constraints so if I reinitialize any subscriptions they will fail to be applied. Have tried editing the properties to just delete data and not drop tables but that still failed.
I've tried setting up subscriber without snapshot - created publication and snapshot, backed up db, copied to subscriber and restored there. See this article: https://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=689428&SiteID=1 This bloke suffered same results and the response from MS was to change the help files, not functionality. Doesn't help us dealing with subscribers via satellite AND unable to deploy snapshots...
I've checked the service pack releases to see if any issues like this are addressed and found nothing relevent.
My gut feeling is that the snapshot is not being generated correctly for some reason - system stored procedure errors perhaps.
So far my experience with replication has been good, with the odd issue or frustrating limitation in older versions, but this is really killing me...

Hi,
i am getting the below error while applying running the Synchronization agent for the Subscriber. I have created replication topology with one central server and one subscriber. Here central server has windows server 2003 and subscriber has windows XP. Both are having SQL server 2005. After creating the merge subscriber, i am runnnig the Synchronization agent manually for the first time. While running that i am getting below error. Anybody aware of this error.

I'm trying to setup merge replication and get the following error from the snapshot agent after I've finished the 'New Publication Wizard'. This doesn't make sense to me as it is an automatic process. Also, it looks like it is complaining about a 'dbo.MSmerge_cont...' view which is a view created automatically for the merge publication.

I have a merge replication. Currently works fine. Publisher & Distributor are on the same server. I need to change the location of the alternate folder for the snapshot files.
I’ll probably just change it through the GUI, but would I use sp_changedistpublisher or sp_changemergepublication if I were scripting everything?
My real concern is the subscribers. Do I have to ‘tell’ the subscribers where the alt folder has been changed to? Do I just run sp_changemergepullsubscription on the subscribers?
I'm converting an existing production replication process to SQL 2005 for testing. My snapshot for a merge replication is failing.

Hi there,
I have setup merge replication which successfully synchronizes with a group of desktop users using SQL Compact Edition.
However now I have setup Article Filters and when I attempt to regenerate the snapshot I get the following error:
Invalid column name 'rowguid'.
Failed to generate merge replication stored procedures for article 'AssignedCriteria'.
When I look at publication properties at the Articles page.. All my tables have the rowguid uniqueidentifier successfully added to tables and selected as a compulsory published column, apart from the table above "AssignedCriteria".. Even when I attempt to select this column in the article properties page and press ok, when I come back it is deselected again. ( The Rowguid column is however physically added to the table)
I have scripted the publication SQL and then totally reinstalled from scratch, including the database but for some reason it doesn't like this table. I remove the article filters, but still this "rowguid" is never "selected" in article properties.
We are using Uniqueidentifiers in other columns as well for historical reasons, but this doesn't appear to be a problem in other tables..
DDL For this problematic table is as follows
CREATE TABLE [dbo].[AssignedCriteria](
[AssignedCriteria] [uniqueidentifier] NOT NULL,
[CriteriaName] [varchar](255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[TargetScore] [numeric](5, 0) NULL,
[HRPlan] [uniqueidentifier] NULL,
[ActualScore] [numeric](18, 0) NULL,
[Criteria] [uniqueidentifier] NULL,
[Employee] [uniqueidentifier] NULL,
[IsActive] [bit] NULL,
[addDate] [datetime] NULL,
[totalscore] [numeric](5, 0) NULL,
[isCalc] [bit] NULL,
[Weight] [decimal](18, 2) NULL,
[ProfileDetail] [uniqueidentifier] NULL,
[rowguid] [uniqueidentifier] ROWGUIDCOL NOT NULL CONSTRAINT [MSmerge_df_rowguid_7FF25DF903B6415FBFF24AC954BC88E4] DEFAULT (newsequentialid()),

Hello guys,
We have customers that are using web synchronization. Could you, please tell us when service pack for the bugs, discussed in thread http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=689428&SiteID=1 will be reliazed?
What replication participants should apply the service pack in a configuration where Subscriber (MS SQL 2005 Express) gets synchronized with Publisher/Diustributor (MS SQL 2005 Standard)?
Thanks.

Hi guys, Im desperately hoping someone here can help me. Ive been trying to set up merge replication between 2 servers all weekend and it keeps failing. Im setting this up as follows
The Publisher/Distributor is a SQL Server 2005 machine, the database being replicated is 4gb, and the only subscriber is a SQL Server 2000 SP4 machine. I set up my publication normally, and set up the push subscription, adn set it to initialize immediately. It weill then start bulk copying and go on for about 3-4 hours before it fails and gives me the errors:

Hello.
I've been having an error when downloading the snapshot agent from our Publisher.
The articles selected are all the tables and all the stored procedures.
The Subscription is created programmatically and so is the synchronization. When trying to synchronize for the first time and when the subscriber tries to download the snapshot I have the following error:

Love that exception message: "Data is Null" - very helpful to someone who is clairvoyant perhaps.
I checked the snapshot bcp files. The tables being merged all have data.
A sample add article command is:
exec sp_addmergearticle @publication = N'MyMerge', @article = N'Phone', @processing_order = 4, @source_owner = N'dbo', @source_object = N'Phone', @type = N'table', @description = null, @column_tracking = N'true', @pre_creation_cmd = N'drop', @creation_script = null, @schema_option = 0x000000004C42CDDF, @article_resolver = null, @subset_filterclause = null, @vertical_partition = N'false', @destination_owner = N'dbo', @verify_resolver_signature = 0, @allow_interactive_resolver = N'false', @fast_multicol_updateproc = N'true', @check_permissions = 0, @identityrangemanagementoption = N'none' ,@force_invalidate_snapshot = 1,@force_reinit_subscription = 1
If you have any ideas on how to fix this, I'd be most grateful. As it is after 6pm I probably won't read this again until morning. Thanks for any suggestions.
The database will grow to 40GB in a short while and I intend to schedule replication every hour. Can this not be done using snapshot replication??

I've been trying to replicate a database to an off site server using snapshot replication. It is scheduled to run every hour but I've noticed when data is changed at the source it never gets replicated to the destination. Does anyone know why?? I can't use transactional replication beause not all the tables have primary keys and they can't be added due to code. Some tables have id colunms and have been created with the Not for Replication option on the subscriber. Any help will be appreciated.
Thanks
Robert
I can set up snapshot replication for those tables without foreign key constraints. But if there are foreign keys in the table, there will be error
message indicating that this object can not be dropped because it is referenced by ....
Do you have any remedy for that? Thanks
2 questions:
1) In snapshot replication, can the subsciber send info back to the publisher (even in a manual process)
2) In snapshot replication, do we need a distributor set up between the publisher and subscriber if there will only be a single subscriber, or can we write directly to it?
Thanks so much for any and all help!
Hi Guys,
We have a production server in East Coast (SQL Server 2000 SP2 - Database size is around 30 Gig). We have a reporting server is the West Coast. We need to replicate (transactional replication every one hour) from East coast to West coast. Is there any way that I can take a backup and restore upto the last transaction backup and then start replication agent on the production (by saying schema and data already exist). Basically we don't wan't to snapshot using FTP or bcp through WAN because it is going to be very slow.
If this is possible, will there be any validation problem.
Please help.
Thanks,

I am using snaphot replication.I did the snapshot replication for the first time
and server B got a snapshot of server A.
Next time i run snapshot i want the incremental data to be replicated and not all..Is this possible in snapshot replication? If not which type of replication should i use?
Hi All,I have set up a snapshot replication, and schedule it to run everynight. The snapshot run successfully, and data get replicated to thesubscribed server. However, data do not get transfer as the second dayand there after. I check the job history, the job (distribution) runsuccessfully. I start the snapshot agent again, then data gettransferred. I can schedule the snapshot agent to run every night, butthis is just not the way it's supposed to be. Is there anyone out therecan give me some help. Thanks.

I am using SQL SERVER 2005 snapshot wizard to create snapshot. But as soon as i create a snapshot it takes away all the indexes and constraint for the tabels on the subscription end although i have this indexes and constraint on Publisher side.
Can someone help me in finding if their is some setting to create a snapshot without losing indexes and constraints or if their is some other way to do this.
Thanks,

Hi is that possible to configure replication in the following situation.
server A is built by snap of server B. Because i am able to create publisher on server B but i am unable to create same on server A.
could any one explain the situation, why it is happening this way.
any help is appriciated.
if you are curious what kind of error i got.

I am looking forward at performing a SNAPSHOT REPLICATION between a 2000-Publisher and a 2005-Subscriber. But on following the wizard the latter is unable to recognize the publisher.
Could anyone help to let me know the possible reason or if there is some setting which i may have missed out?
Thanks,

Hi Everybody:
We encounter a difficult problem in our production environment.
I have a merge replicaiton which contains 10 tables from Server s1 and database d1 to Server s2 and database d2. Among those 10 tables 5 of them are true merge tables ( carry data both ways, from publisher to subscriber and from subscriber to publisher). Other 5 tables I would like them to carry data only one way from publisher to subscriber ( never merge data from subscriber). Anyone has any suggestions how I impliment this?
Thanks in advance.

I get the following error:
Another snapshot is running for the publication.
I just upgraded to Service pack2 and can not get the replication working. I have not clue what is wrong.
Thanks in Advance,

Hello,
We are using Snapshot replication to move data for our Data Warehouse from a server which performs the loading to the production reporting server. We are currently using Sql Server 2005 in both environments. The loading server is setup as the Distributor and Publisher and the production reporting server is setup as the subscriber. However, the replication is not automated instead we only want it to run if the load process is successful. To do this we did not set a schedule for replication but added the jobs that the Replication Wizard created to our own Sql Agent job which manages the load. I have listed the below commands that the sql agent is running for replication in the order in which they are ran.
1) -Publisher [SRVLOADER] -PublisherDB [PRESENTATION] -Distributor [SRVLOADER] -Publication [SRVREPORTER] -DistributorSecurityMode 1
2)-Subscriber [SRVREPORTER] -SubscriberDB [PRESENTATION] -Publisher [SRVLOADER] -Distributor [SRVLOADER] -DistributorSecurityMode 1 -Publication [SRVREPORTER] -PublisherDB [PRESENTATION]
In our own job we run each of these jobs using the EXEC SP_START_JOB() procedure. Each job listed above runs under their own PROXY account.
Finally, we are experiencing an intermittent problem where the Agent will report it is unable to Copy data into "X" table, with "X" being any one of the tables in the reporting database. This has only ever occurred during the automation process and not from manually running each agent job. This problem also might not occur for a couple of days and then might occur 2 or 3 days in a row, which has led us to question the dependability of this approach.
In closing I would like to ask if there is a problem with the way we have set it up? Something we could do to improve the process so it becomes more reliable? Any advice would be greatly appreciated.
Is there anyway to prevent deadlocks during the snapshot replication?
I understand that you can minimize by maybe creating a couple different snapshots (mixing tables to minimize locking while snapshot is being created), but is there any other way?
Thank you
I configured the transactional replication using push method. I use the option generate snapshot. Until the Snapshot complete, I didn't any tables in the subscriber db.After that also I can see in some tables it has indexes and some tables it doesn't but it has data in that table .
How does the bulk copy works from snapshot?i.e. is it first create the table with columns then insert data later it will create the indexes...How the sequence works in the subscriber.
Hello,
Harry Half wit here!!
I know that snapshot replication is the simplest form of syncing with SQL server and I can't even figure that out today!!.
I keep getting myself confused as to who should be configured to be a publisher, distibutor or subscriber etc etc.
My scenario is simple:
1 server creating a daily snapshot of a table and then 1 remote laptop (msde) pulls the snapshot into it's own database.
Heres what i did so far;
I configured the server to be a publisher and distributor (is that right?) and didn't set up any subscribers because i want to do that from my remote.
From the remote I did nothing but go into EM tools"create new pull subscription" but I cannot see the publication on the server.
SHould I set my remote to be a distributor to do this?
any help very much appreciated!!
Snapshot replication.

Last status message:
"The job failed. The Job was invoked by User distributor_admin. The last step to run was step 3 (Detect nonlogged agent shutdown.)."
What should I do to make the synchronization work?
