Default Conflict Resolver In Sql 2000
Sep 20, 2005Hi, I'm replicating a database between two instances of Sql 2000 using Merge Replication. I have no custom resolvers at present but I'm seeing something unexpected.

Merge Replication Does Not Work With Non-default Conflict Resolver
Aug 4, 2015I have been evaluating merge replication, 'push' subscription on SQL Server 2014. If the default resolver is used (I refer to @article_resolver parameter of sp_addmergearticle), all seems to work as expected. However if I use "Microsoft SQL Server Subscriber Always Wins Conflict Resolver" (or any other MS standard resolver for that matter), if the Subscriber is on a different machine, the merge agent invariably gives the following error: "The process could not initialize <resolver_name>. Verify that the component is registered correctly."
This does not happen if the Subscriber is on the same machine as the Publisher and Distributor.
The problem seemed to exist in SQL Server 2008 according to some posts but it has been apparently fixed since then. I've tried the following:
- @partition_options = 0, as was suggested somewhere.
- Copied ssrpub.dll (the resolver dll) to the Subscriber machine (should not really matter as this is 'push' subscription?)
- Registered ssrpub.dll with regsvr32 on the Publisher/Distributor machine.
I've also run sp_enumcustomresolvers on the Publisher machine, and it happily showed all standard resolver, including the "Microsoft SQL Server Subscriber Always Wins Conflict Resolver".
Another thought is, I'm using SQL Server Express as the Subscriber (on the remote machine). Perhaps it does not support custom resolvers? (I'm using the full SQL Server in the 'local subscriber' variant, which does work OK as I mentioned before).
Note also that if I create a new publication via SSMS, the Resolver tab of the Article Properties dialog is empty, i.e. it does not list any resolver. The same tab contains the full list of resolvers though, if opened for an existing publication.
Custom Conflict Resolver
Jan 26, 2006Hi there,
I have created a custom conflict resolver for an article that is using Merge replication. I can register my custom resolver OK, I can change my merge article to use my new custom resolver, but when a conflict occures the replication monitor shows the following errors:
Error messages:
No signature was present in the subject.
(Source: MSSQL_REPL, Error number: MSSQL_REPL-2146762496)
Get help: http://help/MSSQL_REPL-2146762496
The Custom Resolver Component for article 'BRANCH' does not have a valid digital signature. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147198713)
Get help: http://help/MSSQL_REPL-2147198713
At first I thought it was because my assembly wasn't signed, so I signed it. I still get the same error.
I have various debug statements in the assembly and I can see that Initialize and HandleChangeStates gets called ok, but no other overrides.
Can anyone help me please?
Thanks

Replication Conflict Resolver
Jan 18, 2007Hi Everyone!
Here another post on replication.
When conflict occur, I want the user to be able to select witch row to keep and witch to delete.
I've look for system stored procedure, that could help me do the resolution but I've founded nothing.
So I've thought that I could do it by hand, with UPDATE/DELETE query
Take the row in the %TABLE_NAME%_Conflict table and copy it into the real table, than delete the row.
I this the good way of doing it?
Is there any other way?
Thanks !

Example Of Stored Proc Conflict Resolver?
Oct 2, 2006
Hi all,
I need to write a custom conflict resolver for an application using merge replication. It's relatively simple logic - compare the two rows from the publisher and the subscriber and the winner is based on the value of one particular column.
Reading BOL gives me the input parameter list for the sp, and specifies that the output should be exactly the winning row. What is doesn't give is any example of how to do this, in particular how to access the two rows in conflict so that they can be compared.
I can do this by dynamically building SELECT statements, one connecting to the table locally on the publisher and another connecting to the subscriber using the form SERVER.DATABASE.OWNER.TABLE, but this requires me to explicitly have the subscriber as a linked server to do this. An example of my revolting code is appended to this post.
Is this what I have to do, or is there some table I can access on the publisher that has the conflicting rows in so I can compare them without going back to the subscriber?
Thanks for your help
Richard

Need Help On COM-based Custom Conflict Resolver
Dec 21, 2006Hi everyone,
I am working on a COM-based custom conflict resolver (vb.net) for a merge replication problem that I am having. This is what I am trying to accomplish. 1. Have a Last_Upd_Dt column. 2. When there is a conflict between publisher and subscriber on a column, the winner is the most recent date in Last_Upd_Dt and want the value for that column from that source. 3. If there is no conflict on a column and the column was updated by either the publisher or subscriber, I want to keep the change made by the publisher or the subscriber. (i.e publisher made change in col #1, subscriber made change in col #2, no conflict, the resulting row will now have the col #1 value from publisher, col # 2 will have value from subscriber. Essentially merging the changes.)
Does anyone have any examples of a COM-based Conflict Resolver that implements ICustomResolver for SQL Server 2005? Can this be done using the Business Logic Handler (examples?) ?
TIA

Creating And Configuring Custom Conflict Resolver.
Aug 12, 2005Hi
View 1 Replies View RelatedFalse Merge Conflicts - Impact On Conflict Resolver
Oct 12, 2007I am using SQL 2005 build 9.0.2227
I have a custom conflict resolver - which fires on update conflicts (using row level tracking)
I have had a couple of occasions when the resolver has failed with the following error:
"The schema of the custom Dataset object implemented in the business logic handler does not match the schema of the source Dataset object. Verify that the custom Dataset object has been correctly defined"
In both cases I found that the row for which a conflict was being handled was not a conflict at all. One was a straightforward non conflicting update at the publisher and the other was a similar update at the subscriber.
I got round the problem by temporarily using a fix version of the conflict resolver dll that either set the custom Dataset to the publisher dataset or the subscriber dataset - depending on where the update had occurred.
When the first error (publisher update) occurred - the resolver code was basing the custom dataset on the publisher dataset - which was presumably empty - so I changed the code to base the custom dataset on the subscriber dataset. The second error therefore occurred when the custom dataset was based on the subscriber dataset - which again was presumably empty
Note that the tables involved in each occasion were different and neither table is filtered.
Is there a known bug in this area?
I am considering trying to change the resolver code to identify false conflicts in order to workround the problem - but this would be difficult to test as I can't reproduce the problem

Stored Procedure Based Custom Conflict Resolver Truncates Data
May 17, 2007I created a stored procedure based custom conflict resolver in SQL 2005, I return the winning result set and also save that result set to a test table to compare the values. The values saved to the test table are correct but some of the values saved as the conflict winter are truncated.
Example a char(3) filed is updated at the subscriber as 111 and updated at the publisher as 222, in my custom conflict resolver if I use the value from the subscriber the conflict resolver updates the field as 11 , if I use the publisher value the conflict resolver updates the field as 22 . Now the same records is saved to the test table correctly as either 111 or 222 depending on the logic I used. So the result set has the correct values, its after the custom conflict resolver is called where the values is somehow truncated. Has anybody run into this before and what steps can I take to avoid this.
Thank you,

Error While Changing Custom Resolver Between 2005 Publisher And 2000 Subscriber
Sep 25, 2007Hi all,
here is the context of our problem:
- Publisher :
version SQL Server 2005 SP2
table in SQL Server 2000 (80) compatibility level
publication in SQL Server 2000 compatibility level
- Distributor : SQL Server 2005 SP2
- Subscriber : SQL Server 2000 SP4 + hotfixes (version 8.00.2187)
There is only one article in our publication (a simple table with a GUID and a nvarchar(50) columns), and we have left the default resolver.
1 - The first synchronization of the subscription is successfully completed, and it is the same for the different updates/inserts/deletes or conflicts.
2 - Then we change the Resolver of our article by our own COM-Based Custom Resolver (developped in C# 2.0). This resolver only change the default behaviour: the subscriber always win (this is for a test, in the future we will have a complex business logic). All the synchronizations works fine and do what we want in the conflicts.
3 - We rollback the resolver to the default one... and here is the problem!
The synchonizations stop to work correctly. For all of them we've got the same error:
Code SnippetReplprov.dll , 2007/09/25 14:26:07.591, 4000, 16890, S1, ERROR: ErrNo = 0x80045017, ErrSrc = <null>, ErrType = 8, ErrStr = The schema script '

MSDE 2000 Replication Conflict
Jun 28, 2006I am using MSDE 2000 for my replication. the problem is that althought at time creating publication it inserts GUID into every table but if one table in 2 nodes has same primary key, it inserts only one row ( accorrding to prority ). there are some Conflict Reslover methods that can be used for this purpose. i wanted to ask that is there any other way for me to resolve this conflict. i am asking for a new way because my database schema has been created and a lot of coding behalf of that schema has been done.
I'd be thankful if you guide me.

SQL Server 2000 Interactive Conflict Resolution
May 31, 2006I'm having some problems getting Interactive Conflict Resolution working under SQL Server 2000 SP4. I have set "Allow Subscribers to resolve conflicts interactively" under the Resolver tab for the article in the publication. I have set "Enable synchronization using Windows Synchronization Manager" and "Resolve conflicts interactively" under the Synchronization tab for the subscription. I have set "Resolve conflicts interactively" under the Other tab for the subscription properties in the Windows Synchronization Manager. However, when I generate conflicting data in the publishing and subscribed DBs and synchronize using the manager, the resolution is automatic and a warning pops up informing me that "conflicts occurred while syncronizing the data and were resolved according to defined rules." Am I missing anything here?

Custom Resolver For Merge Replication
Sep 7, 2006Hi there!
I'm trying to create a custom resolver for merge replication exactly like in the MS example.
It seems to work, but only ONE time. If I change, insert or delete a
record in a table the second time, the subscriber monitor comes with
the following errors:
Error messages:
Attempted to read or write protected memory. This is often an
indication that other memory is corrupt. (Source: MSSQL_REPL, Error
number: MSSQL_REPL-2147199411)
The Merge Agent encountered an error when executing code in the
'UpdateHandler' method implemented in the business logic handler
'D:Program FilesMicrosoft SQL Server90COMMyResolver.dll'. Ensure
that the overridden 'UpdateHandler' method has been properly
implemented in the business logic handler. (Source: MSSQL_REPL,
Error number: MSSQL_REPL-2147199411)
This last error is of course dependant on my action (update, delete, insert).
My code is -exactly- like the example (I just stripped out the log message).
Does anyone know why I am "trying to read or write protected memory" ?
The thing is that I'm trying to create an application that detects if a
table changes. Is this the right way to do this anyway or are there
better solutions?
Any help is appreciated! Thanks!

Default Dates To UTC In SQL Server 2000
May 8, 2007Hi all,
I hope this is the correct forum. I have SQL Server 2000 installed on a server located in the USA. The local time zone on the server is EST. Therefore getdate() returns EST time. I now realise that I'd like to be saving all my timestamps in UTC. While I could modify all my stored procedures to use getutcdate() rather than getdate() I wonder if there is a database level setting for time zone that will cause getdate() to return UTC date?
Any ideas?

Creating A Database In MSSql 2000, But NOT In The Default Directory
Sep 28, 2002I am trying to find a solution to a thorny problem I have encountered...
I am a newbie in Sql Server 2000, but have quite a bit of experience in databases, both on PC and mainframe.
I am currently writing a program, which needs, among other things, to create Sql Server databases, to be located NOT in the default Mssql2000 directory, but in the user's home directory.
I am using an ADO connection and trying to execute it, as follows:
The text of the relevant part of the program goes like this:
Dim strCreateDatabase As String
Dim MyCn As ADODB.Connection
Set MyCn = New ADODB.Connection
With MyCn
.ConnectionTimeout = 25
.Provider = "sqloledb"
.Properties("Data Source").Value = "MOP"
.Properties("Initial Catalog").Value = ""
.Properties("Integrated Security").Value = "SSPI"
.Open
End With
strCreateDatabase = "Create Database Rimon on (" _
& "Name = Rimon, Filename = '\mopusersMR_DiazsalpmsdataRimon_Data.mdf', " _
& "Size = 20, MaxSize = 100, FileGrowth = 5) " _
& "Log on (Name = 'Rimon', Filename = 'c:usersMR_DiazsalpmsdataRimon_Log.ldf', " _
& "Size = 2, MaxSize = 10, FileGrowth = 1)"
MyCn.Execute strCreateDatabase
Both the name of the Sql Server and the Win2K server is MOP.
All the directories exist, and I have full access to them.
When I try to run this command, I get the following message:
File
'\mopusersMR_DiazsalpmsdataRimon_Data.mdf' is on a network device not supported for database files.
When I omit this location, it works just fine.
If I run it on the server, using another directory, it works just fine.
Do you have any idea what I am doing wrong?
Thanks in advance for any help!

Named Instances And Default Instances Of SQL Server 2000

I installed a named instance of SQL Server 2000 and then i passed all my DB
of the 7.0 instance to the 2000 instance.
Then i removed the 7.0 instance, that was the default instance.
So at the moment there is only the 2000 version, but it isn't the default
instance
Can the 2000 instance become the default instance? (So that clients can
connect to it simply through computer name, and not creating an alias)
