How do we know our schema changes will propagate to subscriber without breaking the replication? Is there any t-sql command to find out the option true or false?
View 2 RepliesIs there a way to force the snapshot to use a format file when bcp'ng the data to the subscriber?
The publisher and subscriber schemas are slightly different. Mainly added columns to the subscriber.
We have a post snapshot script that updates these additional columns on the subscriber.
I'd like to force the snapshot to use a format file, so it doesn't error when initially loading the data to the subscriber.
Is this possible?
Hi
If a column is added to a table which is a published article in a transactional replication, is it sufficient to do the following?
- drop subscribers
- amend the publication by dropping the affected table, then re-adding it
- re-pushing to subscribers
Or do I have to drop the entire publication and recreate it?
TIA
Is there a script to find which non-clustered indices are replicated? I know i can do this easily through GUI , having a script will make my life much easier ....
View 0 Replies View RelatedI am getting the error The transaction log for database 'ReplicationDB' is full due to 'LOG_BACKUP'.log_reuse_wait_desc from sys.databases is showing logbackup
The database is subscribed database. We configured transactional replication. But the transactional replication is getting errors and failed. Is there relation b/n this replication failures and log growth in subscriber db?
We have a large database with a small number of large tables in it (and a larger number of SMALLER tables), and it is a publisher for a transactional replication scenario. When I create a snapshot to initialize a new subscription, I notice with the larger tables that sometimes it generates multiple files in the snapshot folder, usually in multiples of 16, and numbers them like this:
MyTable_3#1.bcp
MyTable_3#2.bcp
...
MyTable_3#16.bcp
With other tables, I'll get just one LARGE snapshot file, named:
MyOtherTable_4.bcp
In the latter case, the file can be very large (most recent is 38GB).
In both cases, the subscription will eventually be initialized, but the smaller files will generate separate log entries every few minutes in the Replication Monitor, showing 'Bulk Copied data into 'MyTable' (34231221 rows)', whereas the larger table will generate only ONE log entry, showing 'Bulk coping data into table 'MyOtherTable', and it may take a couple of hours before there is anything else showing...except for an entry saying, 'The process is running and is waiting for a response from the server.'
My question is: what would be the difference between the two tables that would result in one generating MULTIPLE snapshot files, the other only a single, much larger one? The only difference I can see in the table definition is that the one generating multiple files has a clustered index, whereas the others do not.
There is a SQL Server 2008 R2 SP3 Clustered Instance that has Transactional Replication. It is by no means a large replication setup in terms of data/article count. SQL Server was recently patched to SP3 and is current on Windows 2008 R2 Patches.
When I added a new article to replication (via 2014 SSMS GUI) it seems to add everything correctly (replication tables/procs show the new article as part of the publication).
The Publication is set to allow the snapshot to generate for just new articles (setting immediate_sync & allow_anonymous to false).
When the snapshot agent is run, it runs without error and claims to have generated a snapshot of 1 article. However the snapshot folder only contains a folder for the instance (that does have the modified time of the snapshot agent execution) and none of the regular bcp/schema files.
The tables never make it to the subscribers and replication continues on without error for the existing articles. No agents produce any errors and running the snapshot agent w/ verbose output provides no errors or insight into any possible issues.
I have tried:
- dropping/re-adding the article in question.
- Setting up a new Snapshot Folder
- Validated all the settings and configurations
I'm hesitant to reinitialize a subscriber since I am not confident a snapshot can be generated. Also wondering if this is related to the SP3 Upgrade, every few months new articles are added to the publication and this is the first time since the upgrade to SP3 that it has been done.
Can you use Transactional replication for exchange data between tables where schema is not matching?

I need to setup snapshot replication for 1 large table.
Source table: SourceDatabaseName.dbo.MyTable1
Target table: TargetDatabaseName.CustomSchema.MyTable1
In the above example, how can I specify the target DB's CustomSchema name (it's currently creating dbo, not CustomSchema)
Hi
I need to setup transactional replication for a production server.
The tables (articles) at publisher being replicated can expect schema changes.
Is there any way to reflect schema changes at subscriber using transactional replication.
Early Thanks,
Salman Shehbaz.
Apart the IDENTITY property, what other properties or attributes are not transferred to the target schema?
I know that one can use NOT_FOR_REPLICATION for identities, but I am interested in a (complete?!) list of metadata objects that transactional replication *prefers* not to transfer across to the target by default.
TIA
Hello,
I'm interested in combining the Peer-to-Peer Transactional Replication and Standard Transactional Replication to provide a scale out solution of SQL Server 2005. The condition is as follows:
We may have 10 SQL Server 2005 (1 Publisher + 9 Subscriber) running transactional replication in the production environment and allow updates in subscribers. To offload the loading of the publisher, we plan to have 2 Publisher (PubNode1 and PubNode2) using Peer-to-Peer Transaction Replication and the rest 8 subscribers will be divided into 2 groups. The subscribers 1-4 (SubNode1, SubNode2, SubNode3, and SubNode4) will be set to be standard transactional replication subscribers of PubNode1, and the rest 4 subscribers (SubNode5, ..., SubNode8) will be set to be standard transactional replication subscribers of PubNode2.
Is it possible to setup above 2 Publisher + 8 Subscriber topology?
Also, could we set the 8 subscribers with updatable subscriptions to achieve each node is updatable?
We do not plan to set all the 10 nodes using Peer-to-Peer Transactional Replication as it is necessary to make sure n*(n-1)/2 (i.e. 45) peer-to-peer connections is reliable. It seems that the maintenance cost is high if the servers are not in a LAN and the topology is very high coupling. So we prefer to divide the 10 nodes into 2 groups and reduce the cost of each node to maintain the connections to all other sites.
That's the scenario.
Any feedback is welcome and appreciated.
Thanks,
Terence
Our database has grown to the point where our current server is struggeling with the query load. One option is to get a 4 processor machine with 16GB of RAM, but I'm also looking at transactional replication as a solution. Currently we run dual Xeon with 4GB of ram (using the /3GB switch in the OS) We have SQL 2000 Enterprise.
The idea is to setup a secondary server with transactional replication pushed from the main server, so that some SELECT-only queries can be executed on the secondary server - thus taking load of the main one. We should be able to add PKs to the small number of tables that currently don't have them, and we should be able to run all updates / inserts on the main server.I'll setup a push-subscription for the entire DB (maybe excluding some log tables) and then for ceratain stored procedures I'll direct our applications to use the backup instead of the main server.
So: Is this a good idea? Is it easy to backup the server using transactional replication? How much extra overhead will this mean for the main server?
we have the standard licensed copy for sql server 2005
while configure transaction replication not allow to move
message is required licesence for replication again i have to get license for
replication
please advice
I have automated process, which synchronizes a transactional publication using initialize from backup approach. It drops subscriptions and puts them back again once the restore on the subscriber is completed.
Dropping the subscriptions causes a lot of blocking and deadlocking. I've decided to remove those steps, but it causes loss of data on the subscriber.
Is it a must to drop and re-create the subscriptions during such process? If not, how can I avoid the loss of data?
We are attempting to rollout a name and address system to 10,000 users who will use an application connected to an MSDE database.
We are using transactional replication to distribute data updates to them. Clients are connecting via the On-Idle feature of Synchronization Manager to grab transactions.
Server spec:
Network card: 1GB
Processors: 2* Xeon 3.2Ghz
Server spec: DL380 2Gb memory
Concurrent connections set to: 600
Disc: RAID 10 with 6400 controller
We are not using hyper-threading.
So far we have rolled the system out to 3500 subscribers, 500 per day.
Each day a subsciber will receive at least 400 transactions and 5000 commands.
Latency is 6 seconds, delivery rate 180 commands per second at less busy times.
Latency is 14 seconds, delivery rate 127 commands a second at busy times.
I have seen it get as slow as 0.04 commands a seconds at busy times.
The server becomes incredibly slow when there are more than 50 concurrent connections.
We are seeing 100 CPU for most of the day as clients connect to the distributor at various times. Lunchtime is particularly busy when people go to lunch, leaving their machines idle. We see lots of "time-outs" and "unable to connect to distributor" messages on the replication monitor during peak times.
What can we do to improve the performance of the distribution server?
Are we being over-ambitious by selection SQL Replication for this scenario?
Thank you for any help!
Best wishes

Hi,
I'd appreciate any help i can get here. I'm working with an MS SQL Server 2005 SP2 db on a Windows 2003 OS. I set up replication from an Oracle 10g instance a few months ago, and everything was working until i installed SP2 for SQL Server.
I get the following error:

I can get snapshot replication to work just fine, but transactional replication throws up the error above.
Anyone with any ideas on how i can proceed?
Thanks in advance!

We have installed 2014 sql server. We have currently 2008r2. We have to run the real time report. So we need to set up transactional replication b/n those two servers. We need to use 2008r2 as publisher and 2014 as subscriber.
Is it ok to have subscriber higher version than the publisher?
Any experience of success or failure setting up CDC on the subscriber end of transactional replication?
Also for a bonus answer, why are explicit index operations not permitted (I'm assuming this is even on the publisher?) From BOL:
• Explicitly adding, dropping, or altering indexes is not supported. Indexes created implicitly for constraints (such as a primary key constraint) are supported.
I have created a publication on SQL 2014 SP1/CU1 it is going to a distribution server also a SQL 2014 database. The subscriber is also SQL 2014 SP1/CU1. When I set it up there are no errors. I fire up Replication MGR and it looks good after the snapshot and distribution agent have been started. Again, no errors. When I do a tracer token the information gets to the distributer in 1 - 4 seconds but it never gets to the subscriber, the tracer token monitoring screen only shows pending for distributor to subscriber.
I can upload the scripts used to create the publication and/or the subscription but am a little hesitant because of server names in the scripts.
Can we create the Database with two schema and having the separate file group for each schema.

Hi,
Transactional replication allows updatable subscriptions where changes at the subscriber are replicated up to the publisher, this can happen via Immediate Updating subscriptions, Queue subscriptions and P2P (new in SQL 2005), all forms of Transactional replication.
Any compared document between merge replication and Transactional with updatable subscribtion ?
Thanks,

Hi,I have transactional replication set up on on of our MS SQL 2000 (SP4)Std Edition database serverBecause of an unfortunate scenario, I had to restore one of thepublication databases. I scripted the replication module and droppedthe publication first. Then did a full restore.When I try to set up the replication thru the script, it created thepublication with the following error messageServer: Msg 2714, Level 16, State 5, Procedure SYNC_FCR ToGPRPTS_GL00100, Line 1There is already an object named 'SYNC_FCR To GPRPTS_GL00100' in thedatabase.It seems the previous replication has set up these system viewsSYNC_FCR To GPRPTS_GL00100. And I have tried dropping the replicationmodule again to see if it drops the views but it didn't.The replication fails with some wired error & complains about thisviews when I try to run the synch..I even tried running the sp_removedbreplication to drop thereplication module, but the views do not seem to disappear.My question is how do I remove these system views or how do I make thereplication work without using these views or create new views.. Whyis this creating those system views in the first place?I would appreciate if anyone can help me fix this issue. Please feelfree to let me know if any additional information or scripts needed.Thanks in advance..Regards,Aravin Rajendra.

View 0 Replies View RelatedI am trying to test simple replication (only tables) of a database that resides on a SQL Server 2005 instance to a SQL Server 2000 instance. The Publisher and Distributer are set up on the SQL Server 2005 instance for Transactional replication. The subscriber is set up on in the 2000 instance. Replication Monitor shows the following error after applying a few scripts:
"Category: SQLSERVER Source SQLSERVER2000 Number: 170 Message: Line 6: Incorrect syntax near

Here SQLSERVER2000 is the name of my 2000 instance, as should be obvious.
Beyond this point, replication fails. Any pointers as to where the problem could lie? Is this a known backward compatibility issue? I've checked all tables in the database and none contain any datatype that is new to 2005 (the database was actually created in and for SQL Server 2000.
Replication from 2000 to 2005 works fine, but the other way round is failing as described above. Any clues?

I am looking for bidirectional transactional replication using updatable subscribers (queued or immediate) . Is it possible to replicate the image data from the updatable subscribers to the publisher. I understood that the Image data can't be replicated to the publisher from the updatable subscriber. I am not using the WRITETEXT or UPDATETEXT. I am using just INSERT and UPDATE for image data type transactions.
Any thoughts on this is greatly appreciated.
Thanks in advance
The requirements are:
1. the user has read-only permissions to dbo tales.
2. the user can do everything within the rpt schema, which contains all objects analyzing dbo tables.
3. the user does not have any permission outside rpt schema, except permissions in #1.
The current solutions are:
1. grant the user select only on dbo tables.
2. make the user the owner of rpt schema.
3. Grant the user database permission on create table/create procedure/create view/create function.
My question is - in step 3, should I just grant "Alter" database permission to the user? Granting Alter seems to be cleaner and simpler. According to MSDN,
"Alter" confers the ability to change the properties, except ownership, of a particular securable. When granted on a scope, ALTER also bestows the ability to alter, create, or drop any securable that is contained within that scope.
I'm currently trying out transactional replication with updatable subscriptions across two 2005 servers.
