Can I Set A Default Range For The Identity Values For Merge Replication?
May 8, 2006
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 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
run out of identity ranges, synchronize the republishing Subscriber to obtain more
identity ranges before restarting the synchronization. If a Publisher runs out of identit

Any help would be great

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!

Hello all,
I am trying to think my way through a solution which I believe others have probably come across... I am trying to implement a matching routine wherein I need to match an address against a high value and a low value (or, for that matter an input date vs. a start and end date) to return the desired row ... i.e. if I were to use a straight vb program I would just use the following lookup:
"SELECT DISTINCT fire_id, police_ID, fire_opt_in_out, police_opt_in_out FROM ipt_tbl " & _
" WHERE zip_code = @zip_code AND addr_prim_lo <= @street_number AND addr_prim_hi >= @street_number " & _
" AND addr_prim_oe = @addr_prim_oe AND street_pre = @street_pre AND street_name = @street_name " & _
" AND street_suff = @street_suff AND street_post = @street_post " & _
" AND (expiry_date = '' OR expiry_date = '00000000' OR expiry_date > @expiry_date)" & _
" GROUP BY fire_ID, police_ID, fire_opt_in_out, police_opt_in_out"
My question, then, is how would you perform this type of query using a lookup / merge join or script? I have not found a way to implement a way to set the input columns? I can set the straight matches without a problem, i.e. lookup zip code = input zip code, but can't think of the correct way to set comparisons, i.e. lookup value 1 <= input value AND lookup value 2 >= input value
Any suggestions?
thanks for your time...

I am using merge replication with automatic identity range management
I want to be able to give a disconnected subscriber a warning message if a certain percentage of the allocated subscriber identity range has been used
- so that they can make sure they reconnect soon to obtain a new identity range
I can get the current identity value OK, but I can't find a good way of finding the current permitted primary and secondary ranges
The information is available in the check constraint, but I don't really want to have to parse this!
CONSTRAINT [repl_identity_range_0DF907AC_40CF_4849_9BD0_2173C90A3805] CHECK NOT FOR REPLICATION (([ContactID]>(10000040000.)
AND [ContactID]<=(10000050000.) OR [ContactID]>(10000050000.) AND [ContactID]<=(10000060000.)))
I can't find any system view which will provide this information
Is there a recommended way of doing this?
Thanks

Hello,I'm getting the following error message when I try add a row using aStored Procedure."The identity range managed by replication is full and must be updatedby a replication agent".I read up on the subject and have tried the following solutionsaccording to MSDN without any luck.(http://support.Microsoft.com/kb/304706 )sp_adjustpublisheridentityrange (http://msdn2.microsoft.com/en-us/library/aa239401(SQL.80).aspx ) has no effectFor Testing:I've reloaded everything from scratch, created the pulications from byrunning the sql scripts generated,created replication snapshots andstarted the agents.I've checked the current Identity values in the Agent Table:DBCC CHECKIDENT ('Agent', NORESEED)Checking identity information: current identity value '18606', currentcolumn value '18606'.I check the Table to make sure there will be no conflicts with theprimary key:SELECT AgentID FROM Agent ORDER BY AgentID DESC18603 is the largest AgentID in the table.Using the Table Article Properties in the Publications PropertiesDialog, I can see values of:Range Size at Publisher: 100,000Range Size at Subscribers: 100New range @ percentage: 80In my mind this means that the Publisher will assign a new range whenthe Current Indentity value goes over 80,000?The Identity range for this table cannot be exhausted! I'm not surewhat to try next.Please! any insight will be of great help!Regards,Bm

I'm having a problem with merge replication. Â My publisher and subscriber are SQL 2008 SP1, and my distributor is SQL 2008 R2. Â Currently, there is no access to the subscriber data aside from the replication agents, so there are no data changes going on there, data is only being modified on the Publisher. Â My plan was to get everything setup and do some internal testing before releasing the subscriber for use.

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.

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....???

Howdy all,
I've run into an interesting scenario that I can't seem to resolve.
We have a table that we are using to create sequence ids. It's literally a table with a single field with the identity value turned on.
create table ident (seq_id int identity(1,1) primary key NOT NULL)
If I want to grab a new sequence id, I can execute
INSERT INTO
ident
DEFAULT VALUES
SELECT scope_identity() AS seq_id
All is well and good. However, now let's suppose that instead of just one, I'd like to get a range of values.
If the table had one other field in it, I could do the following
create table ident2 (seq_id int identity(1,1) primary key NOT NULL, placeholder char(1))
GO
;
WITH RECORDS AS
(
SELECT
CAST('A' as char(1)) AS col1
UNION ALL
SELECT
char(ascii(col1) + 1)
FROM
RECORDS
WHERE
col1 < 'C'
)
INSERT INTO
ident2
OUTPUT
INSERTED.seq_id
SELECT
NULL
FROM
RECORDS
Can this be done if there is only the identity column and if so, someone care to educate me?

From a design perspective, all I can say is "it's not mine" but I do have to live with it, or at least my coworker has to live with it. I'm merely trying to prevent them from opening a cursor and calling the default values version 45M times and no, that's not an exageration.

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?

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

I 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.

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?

This is a very basic question on replication.
I'm having a central Server with SQL Server 2005 Standard Edition and Other sites with Sql Express Server 2005.
Other sites will also be adding New records and data will be replicated to Central server and from there it will be distributed to all sites.
Question is that if Other sites are also adding Records how i can assing Identity values in those databases. There are few restricitons on this :-
1. I don't want to use GUID.
2. Numbers should be sequential that is after 1000, 1001, 1002 etc. should come.
i thought of adding Negative Values in the primary key on other sites and then when data is replicated on central server then replace it with sequential key but i'm not clear on how to accomplish this.
any help will be highly appreciable.

Hello all,
I am just beginning to get into replication and have a couple questions for the experts.
When I set up replication (transactional with queued updates), the default identity range was set to 10,000 for the publisher and 1,000 for the subscriber. I understand that if I try to insert 1,100 records at the subscriber, I will get an error saying that the identity range has been exhausted and I need to run sp_adjustpublisheridentityrange on the publisher and the Distribution Agent for the subscriber.
My questions are:
Why wouldn€™t someone increase the identity range to a very large number, just in case something happens and the publisher/subscriber link is broken for an extended period of time? What are the ramifications to a larger identity range?
Since identity range management is done by the distributor, what happens if the distributor goes down? Do the publisher and subscribers receive errors when they fill their current ranges?
Thanks,
Jarret

I need to import some data into a table that is in a merge bi-directional publication. The table has an identity column that is being "auto managed". The ID numbers I need to import are not within any of the assigned "ranges". They are less than any of the current ranges.
Turning ident_insert on does not work because of the check constraints error. The merge replication triggers validate the ID range as well.
Edit: using SQL 2005 standard publisher and subsciber. Publication is 2005.

If the partitioning MERGE command attempts to drop historic data at the wrong boundary point then data movement between file groups may be necessary before or during the next index rebuild. The script below creates 2 test tables, one using a range right function and the other using range left. The partitioning key is a number between 0 - 59, an empty partition is maintained at the start and end of ranges, 4 partitions contain data in the ranges between 0-14, 15-29, 30-44, 45-59. Data in the lowest range (0 - 14) is switched out and a merge command is run, edit the script to try the different merge boundaries, edit the variables at the start to suit runtime environment 'Data Drive' & 'Log Drive' paths.Variables are redeclared but commented out at the start of code blocks to allow stepping through if desired.
--=================================================================================
-- PartitionLabSetup_20140330.sql - TAKES ABOUT 1 MINUTE TO EXECUTE
-- Creates a test database (workspace)
-- Adds file groups and files
-- Creates partition functions and schema's
-- Creates and populates 2 partitioned tables (PartitionedRight & PartitionedLeft)
[Code] ....
The T-SQL code below illustrates one of the problems caused by MERGE at the wrong boundary point. File Group 3 of the Range Right table is empty according to the data space views, it cannot be dropped though. File Group 2 contains data according to the views but you are allowed to drop it's file.
USE workspace;
DROP TABLE dbo.PartitionedRightOut;
USE master;
ALTER DATABASE workspace
REMOVE FILE PartitionedRight_f3 ;
--Msg 5042, Level 16, State 1, Line 2
--The file 'PartitionedRight_f3 ' cannot be removed because it is not empty.
ALTER DATABASE workspace
REMOVE FILE PartitionedRight_f2 ;
-- Works surprisingly although contains data according to system views.
If the wrong boundary point is used then the system 'Data Space' views show where the data should be (FG2), not where it actually still is (FG3). You can't tell if data movement between file groups is pending and the file group files are not protected from deletion by the OS.
I'm not sure this is worth raising a connect item for but it would be useful knowing where data physically resided after a MERGE RANGE and before an INDEX REBUILD, the data space views reflect the logical rather than the physical location if a data movement is pending.

A have a multi-valued parameter (B) which is dependent on a single-valued parameter (A) on my report. When a value is selected in A, I want all matching values in B to be selected by default and the "Select All" option checked. To do this I have set the Default Values section in B to point to the same dataset as the "Available Values" section. Both A and B have default values so the report runs automatically.
One of the values in parameter A (say Value1) yields more values in parameter B than the other (say Value2).
If I run the report the first time with Value1 selected as the default for parameter A, all values in B are checked correctly. If I run the report with Value2 selected the first time and then change the selected value to Value2 and run my report, all values in B are displayed but only the values that were previously checked (when Value1 was selected), are now checked, leaving the "Select All" unchecked.
What am I doing wrong? Why are all the values in B not checked? The dataset is the same in "Available Values" section and "Default Values" section.

I have few tables, which are replicated and partitioned. They also have archival process. I want to avoid having to run that same process on the subscriber.
Replication of partition switching is easy. However I am not sure how to replicate merge range and empty filegroup/file drops.
There the following article options:
Copy file group associations
Copy table partitioning schemes
Copy index partitioning schemes
I am not sure if these are enough to implement the replication of merge range and empty filegroup/file drops.
I could not find and option to copy partition functions.

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).

suppose you have a large table with 2 columns
create table tick
(
ID bigint identity (1,1) primary key not null
, price money not null
)
and I want to know 3 things
Starting with ID = 1 through ID = (last)
give me the low and high price (that satisfies the below WHERE clause), and the last ID
WHERE high price - low price = 0.10
and the last ID (last) is the minimum ID to satisfy: high price - low price = 0.10
So the last ID will coincide with the record containing either the low or high price, the problem is you don't know which record in that range has the corresponding high/low price, it could be the first record or the 10,000th record.
I am thinking I need to create two summary tables, maybe calculate the min(ID) that goes down 0.01 then the min(ID) that goes down 0.02, etc...
Then calculate the min(ID) that goes up 0.01 then up 0.02, etc..finally join against these two summary tables to figure out which combination of downSummary and upSummary have a difference of 0.10.
