Hello,
I'm trying to setup the Interactive Conflict Resolver in my C# app via RMO. (using SQL Server 2005)
The only article I can find on MSDN or anywhere is involing T-SQL. Can someone please shed some light on this for me specificaly on the subscriber side.
Thank you! Chris
Hi 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

Hi 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 !
Hi, 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.

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

Hi!
I'm trying to create a custom conflict resolver for SQL Server 2000 in
C# but i can't seem to find any source code examples of a *.dll where i
can actually see what needs to be done.
Any help is welcome.
Thanks
Hi 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
Hello,
I see that MS has a conflict viewer that can be accessed by managment studio, however I would like to create one with some customized options. Is there a sample of code somewhere to start this? I could really find anything in BOL. Thanks in advance.

Hi
View 1 Replies View RelatedI 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.
I 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

I 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,

I'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?

I'm having this problem for a while now and can't find any solid answer on the net for it.
I have 2 server in diffrent location ( +- 1200k's) away from eachother. When the msmerge agent run it return the following error and return the status as successfull with the following error information:
(The colum information specified for the MS SQL Server maximum conflict resolver) Resolver is either missing or incorrect. I've change every single article to "Latest chagne wins". Any suggestion. I happend when the power failed and the server got restarted.
Hi 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:

Hi 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!
Hi,
I have created a custom resolver in VB .net (VS2005). The resolver works ( Both Publisher and Subscriber are SQL 2005 ), but I need to be able to debug the code within the resolver. How do I do this? I have tried a number of things without success.
Any suggestions would be appreciated.
Cheers

I have XP Pro SP2 with MDAC 2.8.1022. It had a problem so I tried to reinstall MDAC and got a Fatal Setup Error. This setup does not support installing on this operating system. I downloaded MDAC 2.8 1177 and get the same error.
I thought of uninstalling/reinstalling SP2, but this is a 2 month old Dell Latitude 610 with factory installed XP. There is no Windows Service Pack 2 option listed in the Control Panel > Add/Remove Programs.
There's some other strange things, so I wonder if they are related.
1) I have Paul set up as an administrator account. Some folders like MSSQL show that account with no permissions. I grant all the permissions to Paul for that folder. I come back later and the permissions are gone.
2) I deleted 20 files in Explorer, but 7 of them did not go away. I deleted those 7 again and they instatnly reappeared. I deleted those 7 again and then they finally went away.
3) I get a slow reaction time for things like Windows Explorer and opening and closing programs. This is suprising since it has 2 gig of RAM and 2.3 Gig processor. Could it be a memory handling problem that's causing OS problems. Probably, the memory didn't handle the OS installation well and the whole system is compromised now.

Hi,
I am migrating few my oracle codes to T-SQL. Currently am using & (ampersand) interactive prompt of SQLPlus. Is there any equivalent for the above said in SQL Server.
-Cheeku
Software packages like Microsoft Small Business Accounting and Quickbooks offer a very powerful reporting module that lets end users change grouping, filtering, sorting, etc at run time (having it change the report dynamically infront of them). More importantly, their reporting tools let users click on details on the reports which opens the data in the form based portion of their software.
For example: If the end user pulls up a financial report, lets say "All Bills for February 07", the user get a report of all the bills that have gone out in that time frame. The end user can then click on the actual details in the report, and the Bill will come up in the Windows Forms portion of their software so they edit the bill, or create a new bill.
I have done a very limited amount of reporting in SQL Server, so I am not sure of how they were able to achieve this. If someone could give me some key words or ideas that I can bring up more information from in google, or even on here, I'd appreciate it.
Thanks in advance!

The Report idea, u Got Right, now I want to implement Interactive sorting to Name ,Acronym,ID
Please help me
I know this is not available now, but is it plan in the near future:
I want to be able to set the initial sort order on the interactive sort.
for example, I have a report sorted Asc by Rank. If I click on the interactive sort button on the Rank column, it resorts ascending... totally pointless, and my customers point this out on a weekly basis...
Any plans to add this feature? If not, I will go to connect and suggest it.
Also, does anyone else find this annoying?
Thanks!

I have a report that lists customers. Is it possible to create an interactive mechanism so that a user can somehow select a customer and have a subreport update to show that customer's data, without jumping away from the parent report?
Thanks.

We have an issue with interactive sorting. Interactive sorting works in our Dev and test environments but does not work on our production server. We have deployed exactly the same report to each server. All servers are sp2 (9.00.3042.00). When the interactive sort buttons are clicked on production nothing happens. Has anyone seen this?
I am running a number of SQL instances on my PC. Within the network, I have think server with various System Center components. For compatibility reasons, some features of System Center 2012 R2 had to be delegated to different SQL databases. My question is, because there is now more than one IP address on my system, and each instance of SQL is assigned to its own IP, is there a way to setup DNS and SQL so the namespace points to the desired IP address? For Instance:
MSSQL2008 instance is set to run on = 11.12.13.1
MSSQL2012 is set to run on = 11.12.13.2
IN DNS:
A Record: Mike-PC = 11.12.13.1
A Record: Mike-PC = 11.12.13.2
If I want to use MSSQL2008 by specifying Mike-PC as the DNS name, how would I do that with 100% accuracy? If there is another way to get the job done, I am more than willing to approach this differently.
Bill,
You say, "we enjoy the option of specifying sorting for
multiple columns within the matrix, table or list within which we
are working." But, when I add interactive sorting to the headers of a matrix, the up and down toggles appear in the preview, but the rows are not sorted after clicking.
This works perfectly fine on tables, as you say, but I have yet to see it on a matrix.
Thanks,
Tom
I can't get interactive sort to work on Report Server reports (but it works on reports I've done in Report Builder using one table per report).
I tried it on a different database in a Report Server report and it did work.
There was another post that talked about the collation, which is Latin1_General_CI_AS_KS_WS for the ReportServer and ReportServerTempDB, and SQL_Latin1_General_CP1_CI_AS for the two databases I reported on. But it seems like I'm not doing something correctly since it works in RB but not RS (though the one database report did work).
Any ideas?
I am trying to create a dashboard that is split into the five main focus areas of Customer, Finance, Management, People and Innovation. Each focus area has a main report and a series of subreports (within a panel). I use the Jump to report: property at the domain level which works well.
My problems arise when dealing with the subreports. For example, in the People focus area the panel contains 4 subreports covering; contractor vs. fte trends, gender balance trends, compliance trends and investment trends.
Ideally I would like to have four tabs which when clicked would show the relevant subreport. I know this can be done via a full report refresh, but it looks clumsy and is more complex and costly to maintain.
I am happy for any method that might change the Subreport property dynamically or set the visibility of the objects. I want to avoid using the toggle capability as this could result in two or more subreports conflicting and being visible at the same time.
We have run into a really bizzare problem after upgrading to SQL Server 2005 SP2. We have a bunch of matrix reports that have interactive sort in the upper left hand corner, the sort based on Numeric and Text fields. For Example
=Fields!City.Value
=Sum(Fields!Pax.Value)
Now for whatever reason after upgrading to SP2 and making NO CHANGES to the reports or under data sources, interactive sorts that use the =Sum(....) no longer work but interactive sorts on text values still work.
Any ideas???
