How to speedup data from subscriber to Publisher on Merge replication?
Is there any we can speed up data from Subscriber to Publisher (uploading).
Subscriber downloading data from publisher running more than 20 hours after drop and recreate subscriber.
Could you please post reply.

For study effect, can I configure merge replication using just one SQL Server Instance?
View 3 Replies View RelatedWe have SQL Server 2000 with merge replication at a Publisher and subscriber.
We have some records getting deleted at Publisher and Subscriber and no conflicts are logged.
We have tried the compensate_for_errors setting and this has had no effect.
This is causing serious data corruption and has now become an URGENT issue. Out tech team are almost out of ideas.
Has anyone experienced this or have any ideas as to what to check next?
How to check if web merge sync is working between a subscriber and publisher thru HTTPS ? SQL port 1433 at subscriber is blocked so no direct connection to subscriber.
View 2 Replies View RelatedHi,
I'm using merge replication to maintain a backup copy of my main (publisher)MSDE database. A push subscription periodically (1 per minute) updates the backup DB.
It's intended that if the main db goes down then the backup (subscription) db can be configured as a publisher. This must all be performed via scripting.
The initial configuration of the main publisher and subscription is controlled via scripting, which works fine.
The problems occur when I try to configure the subsciber to become a publisher. A script is executed on the subscriber but fails at the point when it's configuring the publisher detail. The error is something like "unable to configure a publication for a database setup as an anonymous subscription".
I'm guessing that there are subscritpion artifacts added to the database which need to be removed before it can be configured as a new publisher.
Please help,

I have the merge replication (Push) 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.
I have been looking for a way to replicate data from a DB2 system running on an AIX machine. I found some information related to doing this with SQL2000, but not with 2005. Can this be done - preferably without writing our own provider.
Thanks in advance
We've got x2 data centers in the US:
NYC & SAC
Sadly the hostnames for the boxes I am trying to replicate are similar:
- db1.nyc.mydomain.tld
- db1.sac.mydomain.tld
The servers can talk to each other over all necessary ports however when I generate a push subscription from the publisher, I am asked to add the SQL Server subscriber and it already shows DB1 listed since itself is DB1.nyc. How can I attach the remote subscriber when setting up the subscription from the publisher if the hostname conflicts in my unique scenario?I created a entry on the publishers host file to use db2sac for the SAC IP and entering that alias in as the remote subscriber but no dice.
Hi,
I was wondering if it is possible to setup replication between a 2005 SQL Publisher and a 2000 SQL Subscriber? Is there any special setup steps I need?
Thanks so much,
David
I have taken over a transactional replication setup that is being usedfor fault tolerance (I know, I know...).The scenario I am concerned with is where the publisher goes down due tofailure, so we need to point our application at the subscriber and startupdating the data there. We are not using the immediate updating option.How do I go about re-syncing the publisher with the data that been addedto, or changed on the subscriber, when the publisher comes back online?Thanks,TGru*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

I have a setup of transaction replication between one publisher and subscriber in the Same server.Now, I need to add a new subscriber to the existing publisher. So publisher database name is DB_A and Subscriber 1 name is DB_B. So the new subscriber will be DB_C. Is this kind of setup possible on one server?
If yes then at the time of reinitialization is it going to apply the snapshot on DB_B as well as DB_C?Also let say if due to disk error DB_B gets corrupted then will data be still replicated between DB_A and DB_C? (Assuming publisher, subscriber 1 and 2 are sitting on individual disks).
Hello,
Are there any requirements that dictate the SQL Server version for the distribution agent for a SQL 2000 publisher with a transactional push subscription to a SQL 2005 subscriber?
Thanks in advance,

I am using the "Pull Subscription Wizard" to set up merge replication. I go through all the steps of the wizard and then I hit "Finish" at the end. When it gets to the third step (Creating the Subscription), I get the old:
__________________________________________________ _________
mmc.exe has generated errors and will by closed by Windows.
You will need to restart the program.
An error log is being created.
__________________________________________________ _________
This happens whether I try to do this from my PC or from the actual server I am creating the subscription on.
Has anyone else had this issue? Is there a hotfix I need?
Any help is appreciated.
Thanks,

Hi all,
I'm a rather newbie, not only to this forum but also to sql server having a question to the following issue:
Is it possible to drop/remove/delete the "orphan" of a merge subscription on one instance of sql server without having the (former) distributor/publisher (on other instance) available?
The background is: I had a small replication infrastructure with two instances (on two machines), one the publisher and distributor, the other the subscriber. Now it happened that the publisher/distributor machine was completely set up new without having the replication dropped in advance, what remained on the subscriber is now a database with all the merge/replication tables and the guid columns in the user tables.
Moreover this, an entry remained in the subscription saying that a subscription with the former publisher exists...
Can I remove these "orphans" without having to setup the instance again?
Thank you,
Andy
I am using merge replication with a push subscription type. I am wondering if the updates of the tables on the subscriber side are push to the publisher from the subscriber or pulled from the subscriber by the publisher when the syncronisation takes place. this makes a big diferrence for me and i can't find the answer to this question anywhere...
if anyone could answer it would be really appreciated
Thanks
Using SQL CE 3.1 merge replication. Working fine, but want to make subscription read only. In other words, master/slave pattern.
How is this accomplished?
Hi.
I have setup an SQL Server 2005 Merge Replication.
Now I need to display the status of the replication programatically from the subscriber side, I have checked the documentation which mentions MergeSubscription & MergeSubscriberMonitor but I couldn't know how to use them!!
Any Help ?
Thanks
Using Merge replication between SQL Server 2000 and SQL Server CE,
is there any way that row deletes could occur on the subscriber without a reinitialize
or explicit delete of row on publisher.
More specifically, if there is a row filter that returns a days worth of data with each
days pull, for example, and the filter looked like
select <columns> from Table where UpdateDate < GETDATE() and UpdateDate >= DATEADD(d,1,GETDATE())
would there be some implicit delete at subscriber each day because data sent changed?
My research indicates this does not happen, but I have a colleague who thinks differently.
Hi,
I have setup merge replication between SQL Server 2005 and SQL Server Express. The setup uses web synchronization. (And the setup uses dynamic filter HOST_NAME)
On some of the client machines, replication fails with the following error (when initializing the subscription):
from subscriber merge agent verbose log:
A dynamic snapshot will be applied from 'D:DOCUME~1JBAUMG~1.CORLOCALS~1TempDB101-EQA-SCL_BQDB_BQ_PUB_BQDB'
Validating dynamic snapshot
2007-04-1819:39:45.434 OLE DB Subscriber 'FRG-BAUMGARTENJSQLEXPRESS': sys.sp_MSregisterdynsnapseqno @snapshot_session_token=N'\XXX.XX.XX.XXSnapshotuncDB101-EQA-SCL_BQDB_BQ_PUB20070417180079dynsnap', @dynsnapseqno='5599F67E-A1A9-4573-A14F-9851F6FE4B51'
(Note: XXX.XX.XX.XX is a proper IP of DB, I have just masked it in the post)
The merge process was unable to deliver the snapshot to the Subscriber. If using Web synchronization, the merge process may have been unable to create or write to the message file.When troubleshooting, restart the synchronization with verbose history logging and specify an output file to which to write.
I enabled verbose logging for the snapshot agent for the subscriber, but there was no error there. It is obvious from the log info above that the error occurs only after downloading the snapshot to the client and during applying it to the subscriber by the merge agent.
After I got this error, I tried running the subscriber program again and it successfully replicated on the third attempt. But this behavior is not consistent and it fails for most of the time on some of the machines
Any info on this error?
Hi,
I need a urgent help! The problem is that every synchronization only transfer data from subscriber to publisher, but not the other direction. The publisher is sql server 2005 standard edition, and the subscriber is 2005 express. Is that any stored-procedure to deal with such a problem?
Thanks for any commnet.
Hi,
We have an existing merged replication schema that works well. One of the
tables is named audit. Currently this is a bidirectional transfer. However,
we want a new audit table that will transfer data from the subscriber to the
publisher and not the other way round. I have a script that was generated as a backup script when replication was first created. I have no idea which parameter to change in order to have the merge replication going from subscriber to publisher. Any advise is helpful. Thanks.
We have a central office with a SQL2005SP4 server (yeah, I know... old as heck) that's the main database and it has multiple subscribers in regional offices. Well... one of the regional offices server is failing, and it needs to be replace.
The original server is an ancient Win2003 86x
The Server team will build a new Win2008r2 64x, and use the same name and IP address
And I'm tasked with the SQL part.
I'll be installing the same version/patch of SQL, but 64x instead, and migrate all databases, including the system databases.
How do I handle replication? Do I need to reintialize from scratch? or can I just use the backup as a starting point?
Hi all,
We are using a mix of SQL 2005 and 2000 servers and our "main" database server is running SQL 2005 x64 (SP2 ver. 3042).
Our system has run perfectly for months, then subsequent to an SP2 update we are seeing several instances where the data record counts are different for several tables among all the servers.
We are using Merge Replication, with no filters and published every 2 minutes.
Any ideas?
TIA,
Michael
These errors occur at the subscriber. First, "The merge process could
not query the last sent and received generations" is generated, then
immediately afterwards, "invalid cursor state" is generated. We are
trying to pull a new subscription snapshot from the republisher. The
subscriber has been added and removed from the replusher's pull
subscriptions a number of times for testing. Now, we cannot get the
subscriber to re-sync with the republisher.
Any ideas?
Hi all.
I get the following error when trying to run a pull subscription from the subscriber:
The schema script '' could not be propagated to the subscriber.

I've tried everything I could to solve this problem, but I can't get it working.
Thanks for any advise.

We have a filtered publisher (SQL Server 2012) with several pull and push subscriptions that have been functioning fine for years.
We have just added a new pull subscriber from a remote server. We configured an alternate folder location on the subscriber (pointing to existing path on a remote server). We generated new snapshot and partitioned snapshot, and moved to subscribing server at alternate path.We're seeing a problem we've never seen before:
When the merge agent runs, it applies the schema and performs a few hundred bulk inserts, but then proceeds to 'download changes to subscriber' as though the snapshot is old (it is brand new and should have all transactions). We have never seen this before, i.e. all data is usually applied in bulk when creating a new or reinitializing an existing subscriber.
we marked the subscriber for re-initialization (from both the publishing and subscribing server) with a fresh set of snapshots. The same problem occurred.We have also tried in our test environment (which mirrors production) and the snapshot applies as expected (via bulk inserts).
(It might be relevant to note the publisher was recently upgraded in-place from 2005 to 2012.)
I have a wired situation..!I set up transactional replication on one of my development server (SQL2000 Dev Edition with sp4).It is running fine without any issues and all of a sudden, i noticed inmy repication monitor tab under Publisher where I usually see thepublication is empty now.I do see the snapshot agent, log reader and distribution agent under myagents inside the replication Monitor. But its usefull to see all 3agents in one window under publisher before. What happend? Is there anyway to get that inside that monitor? Has someone encountered thissitation before? Please advise....After that I tried to create a new set of replication on differentdatabase on the same server and i dont see those either underReplication Monitor - Publishers....All it says is (No Items)....I would appreciate any help to correct this issue... Thanks in advance..

I am having a problem creating a publisher.
I have a database, MobileApp, on a server called Server03, which is a subscriber to a database Stock on Server01. I create the database as a subscriber on Server01, and it gets replicated to Server03 correctly.
I now want to use MobileApp on Server03 as a publisher to mobile devices. I click to add a new publication, and add all the tables. I get all the way to the end, but when I click on finish, I get an error for each table - 'an article with a different subscriber_upload_options value already exists for object.
Any ideas please?
Thanks

I have a clustering between Server A and Server B. There is a clustered SQL Server installed.
Server A is a primary node(oltp production server) and Server B is a secondary node.
i've set up transactional replication betw serer A and B. Server A is Publisher and Server B is subscriber. B also has a distribution database. I use serve B for all the reporting purposes.
Currently both servers have sp1.
Now i want to apply sp2 to the server B first since i use it for reporting purposes (just to make sure there are no issues and then after some days i want to apply sp2 on server A which is my prodction oltp server)
So when i apply sp2 on server B , my publisher will have SP1 and subscriber (& distributor) will have sp2. Will this cause any issues with replication?
Any help would be appriciated.
Thanks
hi,
I'm reading the MS online docs about replication. there's something not so clear until so far.
I have one central server and 7 client servers.
Sometimes new data is entered at one client server. This should be replicated (when client comes online) to the Central Server (merge replication).
Also, the other way, once the central server gets new data (that was replicated from a client), it should be again replicated to all 6 other clients (from the central server).
now, who should i configure as the distributor, publisher and subscriber?
Hello:
I am running an application on mssql 6.5, sp4.
We are working on using a database as a publisher and a remote database as a subscriber for one replication in Canada.
WE havw just been told that another application on a different server(publisher/ distribution) wants to replication to our database as a subscriber.
We also will need(as a publisher/distribution) to replication to a second subscriber database after we completely test the first replication to Canada.
Therefore my questions are:
1) Can a database on a local database -- our database -- on one server be a publisher and subscriber to ther different databases?
2)has any one been involved with replication on a database used both as a publisher and subscriber to different replications requirements?
What are the pitfalls aside from the scheduling conflicts?
3) In terms of database space requirements, how much disk space extra do we need? What guidelines should we use? For each table as an article, assuming we are doing the full table, do we add 100% more space or what?
4) Any other pitfalls we should be aware of?
Thanks.
