Merge Replication: Unique Index Error 1505

Mar 23, 2002

We are currently attempting to (Merge) replicate a database between 2 servers; distributor and subscriber. Apparently there are no Primary Keys in the database, and without the input of the developers, we can only assume that data integrity must be maintained by the application and the database is somewhat generic. In any case, what we are experiencing is that when we attempt to replicate, and you may know, you need PKs. Without any, SQL Server has utilized it's own (Row GUIDs). The Snapshot worked fine, but the merge agent reports error 1505.

The error is "CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID %d. Most significant primary key is '%S_KEY'."

The fix and workaround are SP2 and deselecting Unique in the index propoerties of the index raising the error. We already had SP2 on the system. Tried the other and still the same issue occurs.

Microsoft's Knowledgebase has nothing. Any suggestions or fixes would be greatly appreciated.

Merge Replication And Unique Contraints

Jan 26, 2006

Hi,

I have a slight problem which I'm sure must be a common happening. Here's my problem.

I'm using Merge replication and I have a table the has a unique contraint on a non primary key column (the column is called [name]). The thing that goes wrong (for me) is that when a new record is added in a subscriber and a new record is added in the publisher before a synchronization and both records have the same [name] value then when the merge agent runs I get an unresolved conflict because of a unique index violation.

I've read the BOL and I'm left thinking that in order to solve this problem then I must use a custom resolver. Is this the best way of handling such a conflict? Actually if it is I'm still a little stuck as I'm not sure what I could do to help the situation inside the custom resolver anyway!!

Any help would be much appreciated.

Thanks

Graham

Merge Replication And FullText Index

Oct 5, 2007

We are designing a scenario in which we will have a central publisher and several subscribers in a server to server environment using Merge replication. We also will have a fulltext index for one of the tables being replicated and synchronized. What are your recommendations for the index? Would auto change tracking reduce the impact? We are building for a possible 1 billion row table but do not anticipate more than 100K rows at any time of replication.

Thanks,

How To Add A Missing Index To A Table In Merge Replication?

Jul 23, 2005

One 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

Consistency Error On Merge Table Index

repair_fast is the minimum repair level for the errors found by DBCC CHECKTABLE (ks241.dbo.MSmerge_contents ).


There are no other corruption issues on the server that I can find. I do not believe there are any current hardware issues, though I am not on site.

What would be the best way to resolve this? Is recreating or defrag/rebuild the index an option, here? Or can I just run a repair on this? Since it's a merge table, I'm a little gun shy, having limited experience with replication.

Thanks.

SQL Server 2014 :: Error On Unique Index - Duplicate Key When Insert / Select

Aug 4, 2014

I have an issue where I am getting an error on an unique index.

I know why I am getting the error but not sure how to get around it.

The query does a check on whether a unique value exists in the Insert/Select. If I run it one record at a time (SELECT TOP 1...) it works fine and just won't update it if the record exists.

But if I do it in a batch, I get the error. I assume this is because it does the checking on the file before records are written out and then writes out the records one at a time from a temporary table.

It thinks all the records are unique because it compares the records one at a time to the original table (where there would be no duplicates). But it doesn't check the records against each other. Then when it actually writes out the record, the duplicate is there.

How do I do a batch where the Insert/Select would write out the records without the duplicates as it does when I do it one record at a time.

CREATE TABLE #TestTable
(
Name varchar(50),
Email varchar (40)
)
Insert #TestTable (Name,Email) Values('Tom', 'tom@aol.com')

[Code] .....

Merge Replication Error

Aug 25, 2006

In Merge Replication, I am not able to replicate one table having more than 5 GB data to the subscriber. If I have filter on the table I am able to do. I couldn't understand the problem? Any one having any idea on the same?

For your information.

I have 1.7GB free space in C drive. Is it a space problem in C drive? Actually my data base is storing in E drive. It has 30GB free space. But Sql Server installed in D drive it has 2 GB free space.

Thanks in advance

What Is The Difference Between A UNIQUE INDEX And A UNIQUE CONSTRAINT?

Sep 22, 2004

A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.

2. Windows 2003 Server + SP1 (Subscriber For SQL 2000)

I am getting a replication error, I have taken this errors details from merge agent on publisher server.

Find enclosed replication error details in the microsoft document file format (.doc). The document is consist of three SQL Server snapshot rather three diffrent errors.

In the pictures you can find the red & white color cross (wrong sign) on replication monitor tab, I don't know why it is appearing. :confused:

Kindly, give me guidance to rectify this error & setup the marge replication between two SQL 2000 Servers.

SQL 2000 Merge Replication Error

Apr 27, 2006

I have a merge replication publication that has been running for
months. This week the Snapshot started failing, reporting that an
article was not included in the publication. I checked and found
3 articles that mysteriously no longer show up as being in the
publication. When I attempt to add them it reports that it can't
add them because there is already an article by that name in the
publication. Apparently some table has lost its rows for these
articles while another table(s) still has its rows.



Has anyone had this problem? Is there a solution short of
dropping the publication and starting over - a solution that would
literally take weeks for us?



Thanks for any help.

Merge Replication - Subscriber Error

Apr 20, 2007

Hi,

I have setup merge replication between SQL Server 2005 and SQL Server Express. The setup uses web synchronization. (And the setup uses dynamic filter HOST_NAME)

On some of the client machines, replication fails with the following error (when initializing the subscription):

from subscriber merge agent verbose log:
A dynamic snapshot will be applied from 'D:DOCUME~1JBAUMG~1.CORLOCALS~1TempDB101-EQA-SCL_BQDB_BQ_PUB_BQDB'

Validating dynamic snapshot

(Note: XXX.XX.XX.XX is a proper IP of DB, I have just masked it in the post)

The merge process was unable to deliver the snapshot to the Subscriber. If using Web synchronization, the merge process may have been unable to create or write to the message file.When troubleshooting, restart the synchronization with verbose history logging and specify an output file to which to write.

I enabled verbose logging for the snapshot agent for the subscriber, but there was no error there. It is obvious from the log info above that the error occurs only after downloading the snapshot to the client and during applying it to the subscriber by the merge agent.

After I got this error, I tried running the subscriber program again and it successfully replicated on the third attempt. But this behavior is not consistent and it fails for most of the time on some of the machines

Any info on this error?

Merge Replication SQL2000 Error 2812

Hi !

When trying to start a Merge Replication agent I get the following Error message:

The process could not enumerate the changes at the subscriber. 2812

The snapshot agent works fine as far as I can see.

The replication is set up between a Win2000 / SQL7 / SP 4 and a Win2003 / SQL2000 / SP 3a machine. Sqlserveragent on both machines is run as a system account.

Any tip is welcome!

URGENT! Merge Replication Error 2812

Feb 12, 2004

Hi colleagues!

In trying to activate a merge replication between a Win2000/SQL7 distributor/publisher and a Win2003/SQL2000 subscriber I keep getting the following error:

Process could not enumerate changes at the subscriber (error 2812)

Merge publication works fine between the distributor and another subscriber (NT4/SQL7).

When i look at the details of the merge agent history i can see the process stopped with :

call sp_MSenumeratechanges(?,?,?,?,?)

I read article 308743 on microsoft/technet, and there they advise to install SP3a for SQL2000 on the subscriber. Ive done that but the error persists.

SQLServerAgent on the subscriber starts up with a local administrator account, the (physical) server itself is not a member of the local network; (outside the DMZ). The server is declared in the Client Network Utility of the distributor/publisher and is therefore known as a potential subscriber. In fact, the snapshot agent works perfectly (or so it seems).

Can anyone give me a helpfull hint?

Thanks!

Error In Merge Replication The Schema Script...

Jun 25, 2007

I'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!

Error In Merge Replication While Server Syncs

Jun 22, 2006

At first we received error like

"The merge process could not retrieve identity range resource for table..."

then after solving this error we again started syncing of servers manually then we got some other error like

"the process could not enumerate changes to the subscriber".

We tried our best to solve this problem but some error appears each time like

"The process could not deliver the snapshot to the Subscriber."

"The schema script 'sync -t"Design" -o"dbo" -d"\ECOSYSTEMD$FTPMSSQLEcoSystemftpECOSYSTEM_MLEcosystem_MLEcosystem20060619204802Design_1337.bcp" -hORDER( [intDesignId] ASC)' could not be propagated to the subscriber"

again identity erroe emerges and agin we do the same process.

How to solve these problem?

SQL Server Compact Edition Merge Replication Error

Feb 27, 2007

Hi
I am trying to complete sql server compact edition book online walkthrough "Creating a Mobile Application with SQL Server Compact Edition". I am successful to complete it as guided using all default settings (e.g. anonymous access, windows authenticaion etc.) and the sample run on both emulator and my pocket pc svc5000. I have following configuration..

Windows 2000 professional sp4
Sql server 2005 standard edition sp1
VS 2005 profesional edition (sp1 not installed)
Sql server compact edition
Sql server compact edition server tools

But the problem is that in production environment i will not be able to connect to the sql server using named instance (e.g machine_nameinstance_name). i have to use ip address in that situation. so i tried to modify the sample to use ip address in place of named instance and then the problem starts.. I have configued my sql server to allow remote connections using tcp/ip and named pipes using sql surface area config tool.

When using named instance i used following code to Synchronize with sqlserver 2005 with and it worked perfectly :

Try
repl.AddSubscription(AddOption.CreateDatabase)
repl.Synchronize()
Catch err As SqlCeException
MessageBox.Show(err.ToString)
End Try

When i tried to do replication using ip address it shows following error:

Merge Replication Throwing Very Weird Error Messages

I have 16 subscribers to an existing publication configured and synchronizing changes without any issues. The script that I'm using to create all of the subscriptions is as follows:

use [PIC]

exec sp_addmergesubscription @publication = N'PIC', @subscriber = N'machinenameSQLEXPRESS',

@subscriber_db = N'MyDatabase', @subscription_type = N'Push', @sync_type = N'Automatic',

@subscriber_type = N'Global', @subscription_priority = 75, @description = N'', @use_interactive_resolver = N'False'

exec sp_addmergepushsubscription_agent @publication = N'PIC', @subscriber = N'machinenameSQLEXPRESS',

@subscriber_db = N'MyDatabase', @job_login = null, @job_password = null, @subscriber_security_mode = 1,

@publisher_security_mode = 1, @frequency_type = 64, @frequency_interval = 0, @frequency_relative_interval = 0,

@frequency_recurrence_factor = 0, @frequency_subday = 0, @frequency_subday_interval = 0, @active_start_time_of_day = 0,

@active_end_time_of_day = 235959, @active_start_date = 0, @active_end_date = 0

GO

The last one that I added #17, gives the following errors after successfully creating the subscription.

Command attempted:


{call sys.sp_MSmergesubscribedb ('true', 0) }

Error messages:


The merge process could not initialize the subscription. Ensure that the subscription registration exists at the publisher, and reregister the subscription if necessary. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147201011)

I've tried to manually create it using the GUI and get an even stranger error message as follows:

I very obviously have replication installed by virtue of the fact that I have a publication and 16 subscriptions that are currently synchronizing. Any ideas?

Unique Index Vs Unique Constraint

Mar 7, 2001

Hi everyone,
I need urgent help to resolve this issue...
As far as the performance goes which one is better..
Unique Index(col1, col2) OR Unique constraint(col1, col2) ?
Unique constraint automatically adds a unique index
and unique index takes care of uniqueness then whats the use of unique constraint ?

Which one do one use ?

thanks

Unique Constraint Vs Unique Index

Jan 20, 2006

BOL says a unique constraint is preferred over a unique index. It also states that a unique constraint creates a unique index. What then is the difference between the two, and why is a constraint preferred over the index?
