Hi,
I am replicating all tables in the DB. the tables have PKs,FKs and identity columns. While truncating the data from the tables in subscriber getting
the constraint errors. Please suggest how to get rid of this error.

I re-created a publication that was having problems and it gives this error when I start the snapshot agent from SQL Server Management Studio: I am stuck on how to resolve - any ideas?
"The publisher's identity range allocation entry could not be found in MSmerge_identity_range table. Transaction count after EXECUTE indicates that a commit or ROLLBACK TRANSACTION statement is missing. Previous Count = 1, current count = 2."
select * from MSmerge_identity_range returns 19 entries but I don't know how to fix.
I have tried deleting and re-creating but always get this error.
My other publications and subscriptions are working fine and I was able to create a new test publication that worked but can not get this one to work that worked fine up until today.
Any ideas?
Hi
I seem to have a strange problem when applying a snapshot when the tables in the publication have been updated while the snapshot was being generated.
Say for example there is a table called RMAReplacedItem in the publication. When the snapshot starts being applied to the subscriber, a stored procedure called sp_MSins_RMAReplacedItem_msrepl_css gets created that handles an insert if the row already exists (ie it updates the row rather than inserting it). However, after all the data has been loaded into the tables, instead of calling this procedure, it tries to call one called sp_MSins_RMAReplacedIte_msrepl_cssm - it takes the last letter of the table name and adds it to the end of the procedure name.
The worst part is that this causes the application of the snapshot to fail, but it doesnt report what the error is, and instead it just tries applying the snapshot again. The only way i have managed to find which call is failing is to run profiler against the subscriber while the snapshot is being applied and see what errors.
I have run sp_broswereplcmds and the data in there is what is applied to the subscriber - ie the wrong procedure name.
All the servers involved are running sql 2005 service pack 2. The publisher and subscriber were both upgraded from sql 2000, but the distribution server is a fresh install of sql 2005.
While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,

I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?
I have table of three column first column is an ID column. However at creation of the table i have not set this column to auto increment. Then i have copied 50 rows in another table to this table then set the ID column values to zero.
Now I have changed the ID column to auto increment seed=1 increment=1 but the problem is i couldn't figure out how to update this ID column with zero value set to each row with this auto increment values so the ID column would have values from 1-50. Is there a away to do this?
Ok,I just need to know how to get the last record inserted by the highestIDENTITY number. Even if the computer was rebooted and it was twoweeks ago. (Does not have to do with the session).Any help is appreciated.Thanks,Trint

I am having problem in bulk update of a sql server table haning identity column from a datatable( has no identity column) using sqlbulkcopy. I tried several approaches, but it does not show any error nor is the table getting updated. But the identity value seems to getting increased every time.
thanks.

I'm working with a third-party database (SQL Server 2005) and the problem here is the following:
- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).
- The PK of T is an Integer.
Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.
Considering that I can't change the PK, what is the best approach to solve this problem?
To sum up:
* I need to have processes in parallel inserting on T
* I can't change anything on T
* The PK is NOT an Identity

Dear friends
I am a new fellow to replication.What is the problem I am getting is I am not able to create snapShot.Whenever I start Snapshot Agent it is going for half an hour and it will stuck in the case of one view saying like that 'failed to process bulk copy of data from dbo.syncobj_03x666*'.If I am publishing tables only then also I am getting same error.This view created by system.In my case publiher only working as a distributor.I created a SQL username which have access in subscriber & Publisher.Preferably I will be happy if someone suggest what and all are the primary criterias we have to keep in mind while doing Replication
Thanks in Advance

The database will grow to 40GB in a short while and I intend to schedule replication every hour. Can this not be done using snapshot replication??

Yes and I would rather not use dts to accomplish this task.

Do you have direct network connection to remote server? Did you try dts?

I've been trying to replicate a database to an off site server using snapshot replication. It is scheduled to run every hour but I've noticed when data is changed at the source it never gets replicated to the destination. Does anyone know why?? I can't use transactional replication beause not all the tables have primary keys and they can't be added due to code. Some tables have id colunms and have been created with the Not for Replication option on the subscriber. Any help will be appreciated.
Thanks
Robert
I can set up snapshot replication for those tables without foreign key constraints. But if there are foreign keys in the table, there will be error
message indicating that this object can not be dropped because it is referenced by ....
Do you have any remedy for that? Thanks
Hi,
I've problem in replicating data thru SNAPSHOT as I've the tables with Foreign Keys at subscriber end. The Truncate table is not working because these tables
were referenced by a FK. Even for recreating table during snapshot is also same problem. Any suggestions?

2 questions:
1) In snapshot replication, can the subsciber send info back to the publisher (even in a manual process)
2) In snapshot replication, do we need a distributor set up between the publisher and subscriber if there will only be a single subscriber, or can we write directly to it?
Thanks so much for any and all help!
Hi everybody,
We have merge replication between two servers with Sql Server 2000 Service Pack 2, and the Merge agent display the follow message :
The snapshot for this publication has become obsolete. The snapshot agent needs to be run again before the subscription can be synchronized.
But i have changes at the suscriber, How can I do to Merge the last changes if the merge agentes is stopped.
I appreciate any help.
thanks
Hi Guys,
We have a production server in East Coast (SQL Server 2000 SP2 - Database size is around 30 Gig). We have a reporting server is the West Coast. We need to replicate (transactional replication every one hour) from East coast to West coast. Is there any way that I can take a backup and restore upto the last transaction backup and then start replication agent on the production (by saying schema and data already exist). Basically we don't wan't to snapshot using FTP or bcp through WAN because it is going to be very slow.
If this is possible, will there be any validation problem.
Please help.
Thanks,

Suppose i want to replicate data from server A to server B
I am using snaphot replication.I did the snapshot replication for the first time
and server B got a snapshot of server A.
Next time i run snapshot i want the incremental data to be replicated and not all..Is this possible in snapshot replication? If not which type of replication should i use?
We have a training server and I've had a request that after each training session, we have the ability to quickly roll the training server back to its previous state so that the next group of people can be trained with the same examples.
Doing a restore requires that the maintenance (defrag, warm cache, etc..) also runs after that before the server performs fast enough.
So I was thinking of snapshots as an alternative. When you roll back to a snapshot, does that invalidate what's in the cache or have any adverse effect on query plans, stats, or indexes?

Hi All,I have set up a snapshot replication, and schedule it to run everynight. The snapshot run successfully, and data get replicated to thesubscribed server. However, data do not get transfer as the second dayand there after. I check the job history, the job (distribution) runsuccessfully. I start the snapshot agent again, then data gettransferred. I can schedule the snapshot agent to run every night, butthis is just not the way it's supposed to be. Is there anyone out therecan give me some help. Thanks.

View 7 Replies View RelatedHi,
I am using SQL SERVER 2005 snapshot wizard to create snapshot. But as soon as i create a snapshot it takes away all the indexes and constraint for the tabels on the subscription end although i have this indexes and constraint on Publisher side.
Can someone help me in finding if their is some setting to create a snapshot without losing indexes and constraints or if their is some other way to do this.

Need some help, i have some database snapshots files provided from an external source. Need to be able to understand how i get them back into a database format if possible.
Files for example are table1.bcp, table2.bcp with als a file called scheme.sql which sets up these tables in sql but does not populate them. Nothing else was provided except a .vcd file which i dont know whtat its for.
any clues?

I get an error "Error: Subreport could not be shown." when I set subreport rendering from snapshot. When I render subreport with the most recent data everything works fine.
Does anybody know how to use snapshots for subreport? Thanks in advance.
