Replication :: Merge Identity Value Out Of Sync
May 16, 2015
We are running merge replication. My identity value was out of sync and the inserts stopped working. I Reseeded the identity value to 1500000 and ran "sp_adjustpublisheridentity" which set that to the new range (and table constraint)Â in the MSMerge file and table. I discovered my error and Reseeded the table back to 150000. How to I get the new range to be created when it is LESS than 1500000 in the MsMerge file???? Can I use the sp_restoreidentity....???

All,
I am trying to configure merge replication to a SQL CE database using web synchronization.
It works if IIS is on the same box as the SQL Server publisher but when I attempt this using separate boxes I get the following message.
Getting this message
Error messages:

Get help: http://help/MSSQL_REPL-2147201001
I have followed every bit of advice I can find in the MSDN forums, ensuring that the distributor is writing to a UNC and that the perms for the process are correct.
The 2 test servers are not in a domain and I wonder if this is the issue but connectivity between the 2 servers does not appear to be an issue as I am using administrative ids for connectivity for this test.
BOL is all over the place regarding this subject and I am linked out (perhaps the info I need is in there but who can find it?)
Any guidance would be truly appreciated.

thanks 4 ur rpl..well i have a simple doubt if u can guide me it will b gr8 help..well i am developing an application of location based services, in which i am going to store my data on SQLserver 2005 and will fetch the data from it when the user logs in to the user's PDA device so that a user can work offline on the data when there is no connection and when he gets the connection he can synchronize the data with SQLserver 2005. so now i m confuse whether i should use the merge replication or ado.net synchronization framework or RDA?what is the difference between merge replication and synchronization and which is better?

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?

I have the merge replication (Push)Â for SQL Server 2008.The right-click option for Start and Stop Synchronizing in subscriptions has been disabled. How can I stop the merge replication and start again ?
This error happened 1 week after I created the merge replication. The merge data cannot sync to subscriber and only solution I can use is drop and re-create the merge replication again but error would be re-occur a week later. The merge replication work fine before and start from middle on May 2015, but it keep happen right now.

Hi
I am trying to setup merge replication using web sync. I keep on getting the message: The Proxy Auto-configuration URL was not found. Yes I have read all the postings telling me to check my internet explorer settings concerning proxy server and auto-detection - I am not using a proxy - auto detection is unchecked.
Does anyone have another clue?

Hi;
We are performing merge replication between SQL Server 2005 and SQL Server Mobile with more than 1100 handheld, and recently replications are terminating with eror code 80040E19.
We can only avoid the problem by deleting the related user's partition directory and reruning the related user's dynamic snapshot.
Any advice on this issue would be appreciated
Thanks,

Dear all,
How does an identity is affected by merge replication? Can sql control it so that there will be no replication conflict?
Here's the scenario, I have several tables with an identity column. the database resides in a server in the head office, there are several remote sites and remote users which will be running sql 7 desktop edition. Each remote will download only the data subset he is allowed to. Each site will be allowed add new rows on several table. Then they will update the head office server through replication.
Thanks

Sever: sql 2000
Replication: Merge
Issue:
I am having an issue with my audit table, This table is filled by Triggers on various tables through the database. All triggers are defied with "not for replication"
I have allocated 500k ranges, with 80% threshold to the publisher and subscriber databases for this table. The table only holds 225,000 records.
From time to time I get the following error "The identity range managed by replication is full and must be updated by a replication agent. The INSERT conflict occurred in database 'PublicationName', table 'AuditHistory', column 'AuditID'. Sp_adjustpublisheridentityrange can be called to get a new identity range."
When I looked into the issue yesterday I noticed that the identity range being used by replication was 334300001 -> 334799999, however the maximum value in the table was 334300096, meaning that only 95 records were inserted, which means it is no where near the 80% threshold.
Somehow the identity seed on the AuditHistory table had been changed to 334800104, which is outside the allowable range.
My question is what could cause the identity seed to get set to such a high number??
any thoughts would be great!

I have a database table with a simple identity column. As a starting point... when I run the following queries... this is what I get:
SELECT Max(AliasID) FROM Account_Managers
1300006
DBCC CHECKIDENT ('Account_Managers')
Checking identity information: current identity value '1300006', current column value '1300006'.
Now... I set up merge replication, with the plan of allowing SQL Server to manage my identity ranges for me. I set up my ranges to be 100000 on the publication, 100000 on the subscriber, with a threshold of 80.
I would EXPECT to see the constraint
([AliasID]>(1300006) AND [AliasID]<=(1400006)) on the publisher and
([AliasID]>(1400006) AND [AliasID]<=(1500006)) on the subscriber.
However... what I do get is:
([AliasID]>(1300006) AND [AliasID]<=(1400006) OR [AliasID]>(1400006) AND [AliasID]<=(1500006)) on the publisher and
([AliasID]>(1500006) AND [AliasID]<=(1600006) OR [AliasID]>(1600006) AND [AliasID]<=(1700006))
Can anyone tell me why I get the OR... which essentially makes my identity ranges twice as large as they should be?
Thanks in advance.

I was reading this:
"Adding an identity column to a published table is not supported, because it can result in non-convergence when the column is replicated to the Subscriber. The values in the identity column at the Publisher depend on the order in which the rows for the affected table are physically stored. The rows might be stored differently at the Subscriber; therefore the value for the identity column can be different for the same rows."
I don't understand...
If I create a table with an identity column and publish it. Can the values on the subscriber be different when the data is replicated?
Suppose I have a this table:
1 Name1
2 Name2
3 Name3
Column 1 is identity field and column 2 the name of employees.
If I publish this table , the data can be inserted on the subscriber .pe, with 2 name1 and 1 name3 and 1 name2?
What about if the identify fields is a primary key?

Hi all i have setup merge replication with one publisher and 3 subscribers
The replication worked fine for about 2 months then i recieved the following error on all my subscriptions
The Publisher failed to allocate a new set of identity ranges for the subscription.
This can occur when a Publisher or a republishing Subscriber has run out of identity
ranges to allocate to its own Subscribers or when an identity column data type does
not support an additional identity range allocation. If a republishing Subscriber has

Hello I currently have a merge replication set up with 4 subscribers. A primary field for one of my tables is set to a integer indetity.
What Ive noticed is that depending on which database I enter data into, the indentity field (primary key) is set within a certain range I.e
On Server 1 - Values start from 1 then 2,3,4 etc etc
Server 2 - 24001, 24002, 24003 etc etc
Server 3 - 46001, 46002, 46003 etc etc
Server 4 - 68001, 68002, 68003
My question is what happens when these ranges eventually conflict? Do they automatically gain a different range such as 142 001, 142 002 etc etc?
Ive tried looking in SQL Help, and a quick search here, Im just after some confirmation before I implement this to my app.
cheers

If anyone could confirm...
SQL Server 2000 SP4 to multiple SQL Server 2005 Mobile Edition on PDAs. My DB on SQL2k is published with a single dynamic row filter using host_name() on my 'parent' table and also join filters from parent to child tables. The row filter uses joins to other tables elsewhere that are not published to evaluate what data is allowed through the filter.
E.g. Published parent table that contains suppliers names, etc. while child table is suppliers' products. The filter queries host_name(s) linked to suppliers in unpublished table elsewhere.
First initial sync with snapshot is correct and as I expected - PDA receives only the data from parent (and thus child tables) that matches the row filter for the host_name provided.
However - in my scenario host_name <--> suppliers may later be updated E.g. more suppliers assigned to a PDA for use or vice versa. But when I merge the mobile DB, the new data is not downloaded? Tried re-running snapshot, etc., no change.
Question: I thought the filters would remain dynamic and be applied on each sync?
I run a 'harmless' update on parent table using TSQL e.g. "update table set 'X' = 'X'" and re-sync. Now the new parent records are downloaded - but the child records are not!
Question: I wonder why if parent records are supplied, why not child records?
If I delete existing DB and sync new, I get the updated snapshot and all is well - until more data added back at server...
Any help would be greatly appreciated. Is it possible (or not) to have dynamic filters run during second or subsequent merge?

Hello,
We have a couple of tables that can have quite a bit of data each day prior to replication. Can we increase the default values for a table for each subscription? For example we have a table called table1 and on the sqlexpress client they could enter in 10000 rows a day, on table2 it's just 100 rows a day. How can we increase the values to where we do not get the error for table1 stating that the insert failed because it conflicted with the identity range check constraint. Thanks in advance.

Hi All;
I am trying to set up Merge Replication on a database and want to set the IdentityRange Management to Auto for all my tables which use a Identity column.
In the wizard, on Article Properties Page, I can do this by selecting a Table, and going for its properties, but this is a tedious task as I have ~300 tables to set this property on.
Is there another way or a global location where I can set the property to true and even mention the ranges and the threshold, so that I dont have to pick each table and set it individually.
I am also aware of the fact that I can Generate a Script and modify it and run that, but I was looking for some way to do this in the wizard.
Thanks!

Hi,
I read the BOL on how the publisher will had out identity ranges to subscribers, but it was not clear if this was also the case for anonymous subscribers. Will merge replication with identity columns work with anonymous subscribers that sync via HTTPS?

Hi,
is there a way to ensure a merge subscription is synchronised before it is removed from the publisher using SMO? - (it is a push subscription)
I thought I had it as there is a MergeSynchronizationAgent object on the SubscriptionDatabase object, but calling Synchronize() on this throws an exception saying it can't contact the publisher.
Any help would be really appreciated, thanks.

I have 2 DB on SQL Server 7, that are synchronized by a continuous transactional replication.
The tables have a primary key on an identity column. In order to avoid conflicts,
the identities have different seeds, and increment equal to 10.
When the server shuts unexpectedly, the current value for the
identity column goes out of sync, that is it assumes the greatest value inserted.
The workaround is to run DBCC checkident to correct the identity value.
Is it a bug? Did anyone run in the same problem?
TIA

Hi, I have compact sql databases which will be local on multiple users
devices. Due to space constraints, for one of the tables i have had to use
auto incrementing integer which works fine for the local database but i
would like to merge all of the users databases into a global database. The
table format can be seen below:
Code SnippetCREATE TABLE Players
(
ID UNIQUEIDENTIFIER NOT NULL PRIMARY KEY,
FirstName NVARCHAR(32),
LastName NVARCHAR(32)
);
CREATE TABLE Sessions
(
ID INTEGER NOT NULL IDENTITY,
PlayerID UNIQUEIDENTIFIER ,
SessionDateTime DATETIME,
CONSTRAINT pkSessions PRIMARY KEY (ID),
CONSTRAINT fkPlayerID FOREIGN KEY (PlayerID) REFERENCES Players(ID)
);
CREATE TABLE SessionDetail
(
SessionID INTEGER,
Time real,
Power real,
CONSTRAINT pkSessionDetail PRIMARY KEY (SessionID,StrokeTime),
CONSTRAINT fkSessionID FOREIGN KEY (SessionID) REFERENCES Sessions(ID)
);
The Players table will merge fine as GUIDs are used. However, how will the
sync capabilities of compact SQL handle the sessions table? When it pushes
the local data to the remote database will it change the Sessions.ID column
to a unique field (as no doubt lots of people will have 1, 2, 3 in their
local databases and the global database must have a unique ID), and then
transfer this changed ID back to the local database? Furthermore, if it
changes the Sessions.ID column during the merge it will also need to update
the SessionDetail.SessionID foreign key to maintain referential integrity,
is this also handled?
So my question is, how much of this sync and data merge is automated and are
there any good examples or pointers for my scenario? I cannot reasonably use
a GUID for Session.ID as there will be lots of SessionDetail entries and the
size would be far too much.
Many thanks,
Chris

I have 3 SQL databases: A, B and C. A and B are branch databases while C is the central (HQ) database. A & B will be constantly updated while C will updated occasionally and usually will be used for reporting/data browsing. Even though A & B are from different branch, they do have share some data records.
Every day, I will have to sync A & B's new/updated data to C and C to A/B. I know I can use Replication but I can't. You see, A & B are located in our own branch server while C was hosted on a third-party server. The webserver provider for C would not allow me to do any Replication on C.
What other alternatives that I can use to synchronise all 3?
DTS? XML transfer? It looks as if I have no choice but to write my own sync scripts? :((
Anyone has encountered similar situations? Any recommended SQL Tool programs?
Please help. I'm at a loss of what Im going to do.

Hi Guys,
I have tried backing up the replication from Primary Server (Publisher) A and copying over to Subscriber B. When I sync. I am missing the data. I don't know what step I am missing or it is bug on SQL 2K SP3.
I don't know what i am doing wrong.
Can anybody give me a step by step detail how to backup the publisher database and copy to a subscriber and sync by saying the schema and data already available. As we have WAN problem all the times, and when I try the full snapshot of 20 gig it was taking more than 24 hrs and also if the connection fails my snapshot also fails
Please help.

On windows XP there is a Synchronize program in Accessories. When I run our replication scripts on a SQL Server Express on the XP machine and start the Synchronize program there are items there that allow me to replicate as well as set a schedule, etc.
On Windows Vista there is a Sync Center, but replication doesn't show up here.
I've searched high and low on Google and am not coming up with anything useful, which leads me to believe this is something very simple that I'm overlooking...
Does anyone know how to make your replication show up on the Sync Center in vista, or is there another application that I should download?
Thanks,
Brian

Hi all,
I know that adding a column using ALTER TABLE to add a column automatically allows SQLSERVER 2005 to replicate the schema changes to the subscribers, however, I would like to add a new column to an existing article that is being used for merge replication, however, I don't want this column to be replicated. Re-initialising the subscriptions is not a option. Help would be appreciated.
I am using SQLSERVER 2005 (SP1).
