Who Is Distributor, Publisher And Subscriber ?
Mar 28, 2007
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?

For transactional replication, are there any issues and is it even possible to have 32-bit SQL 2000 publisher and SQL 2005 64-bit distributor and subscriber? Thanks

We have a SQL 2000 Server (publisher & distributor) with around 15 databases being replicated (all using merge replication).
My question is the following:
Is it possible to perform Merge replication from a SQL 2000 (acting as the publisher & distributor) to a SQL 2005 server acting as the Subscriber)?
If anyone has a link to any instructions somewhere that would be great.
Thanks

Hi,
We are about to alter our replication architecture from
SQL 2K publisher/SQL 2K5 distributor/subscriber
to
SQL 2K publisher, seperate SQL 2K distributor and SQL 2K5 subscriber.
The subscriptions will be pulled from the distributor and pushed to the subscriber. Basically, all the work will be done by the distributor (in the hope of improving performance).
Has anyone had any experience of a similar architecture? All SQL servers are running with the latest service packs.

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,
John

Does anyone know if there are any known issues with using a 64 bit distributor and 32 bit publisher together?
This is SQL 2005 and Push Merge replication.
Thanks in advance

Hi - hoping some folks here can help me. I've got a SQL 2000, Service Pack 4 database that I need to publish, but I'm getting the following error on the exec sp_addpublication statement when I try to set up publication in Management Studio:
Msg 8526, Level 16, State 2, Procedure sp_addpublication, Line 802
Cannot go remote while the session is enlisted in a distributed transaction that has an active savepoint.
I also tried to set up the Publisher in Enterprise Studio, on the theory that the system sproc was not backwards compatible, and there I got this error:
Error 627: Cannot use SAVE TRANSACTION within a distributed transaction
There is one proc in the publisher's database that uses SAVE TRANSACTION, but it isn't currently being run and it isn't dependent on the table being published. Has anybody else encountered this? Any ideas about how to make this go away?

I am investigating scenarios for our new replication strategy and we have 2 very powerfull machines. 1 however more powerful than the other.
The distributor will be pushing (merge) data to 40 replicas around the globe, the database is about 5GB in size and uses dynamic filtering to sort out who needs what data.
The publisher will only be working with the distributor it is not doing any other work.
I am guessing the distributor will have the majorty of the work to do in this case and should have the more powerful machine. Does anyone know if this is correct?
Thanks in Advance

I have Oracle 64-bit drivers installed. I can run SQLPLUS and it works. I can create linked servers to oracle and that works also. I am having this error when I try to add oracle as a publisher. OraOLEDB.Oracle is already set to 'Allow InProces'.
Msg 21626, Level 16, State 1, Procedure sp_MSrepl_testconnection, Line 110
Unable to connect to Oracle database server 'DTMART' using the Oracle OLEDB provider OraOLEDB.Oracle. For addition information, see SQL Server Error 21626 in Troubleshooting Oracle Publishers in SQL Server Books Online.
Msg 21747, Level 16, State 1, Procedure sp_MSrepl_adddistpublisher, Line 463
Cannot establish a connection to the Oracle Publisher 'DTMART'. Verify connection information and ensure that you can connect to the Publisher through a tool like SQL*PLUS.

Hi All,
Can push and pull subscriptions be configured on the publisher/distributer server?
We have server A running SQL Server 2000 configured as Publisher/Distributor and also a Push subscription (transactional replication) to Server B configured as Subscriber.
The idea was to have Server B as backup server if Server A goes down. Users will continue to update data in server B till server A is up.
Once server A is up, I want to synchronise the up-to-minuit date from Server B to Server A in the form of Transactional replication configured as "Pull Subscription" from Server A.
Is that possible?
Thanks

hi,
Im I want to configure my sqlserver 2005 server as both subscriber and distributor for transactional replication purposes.
I want to configure the sql server 2000 as the publisher.
When I try to configure the publisher in the sql 2000 server, Im not being able to establish the connection with the distributor 2005 sql server in any of the 2 possible cases.
case1-Using windows authentication- message:need to use management studio or SMO
case2-Using sql server authentication-message:authentication failed
Question:
Is it possible at all to do this? or should I make the distributor to reside in a sql 2000 server?
thank you

I am setting up my 2005 Replication system...
publisher = 2005 sp1
Subscriber = 2005 sp1
I created a publication for a single table. Then I created the subscription to another 2005 server. Had to add it as a subscriber in the wizard. Told it to do the snapshot right away.
Everything seems fine right up to the point where it tries to connect to the subscriber... I get a cannot connect error. I have tried all kinds of security context and accounts for the sql agent to run under but nothing seems to work. I cannot even get a linked server to work. I have the subscriber setup to accept remote connections.
I am not sure where to look at next... I never had this issue in 2000.

Hello All,The setting is SQL server 7, on Windows NT.If the distributor can not access the log on the publisher database ( butsubscribers are not deleted yet), will the full backup of the publisherdatabase truncate the transaction log? My guess is, it will not truncate thelog.Can any one confirm please?Thanks,Mokles

Hi,
Server A houses the Production DB which services an OLTP system. Transactional replication is configured on this server which has two subscribers - on two separate servers (servers B and C). The Distribution database currently resides on Server A (which is also the Publisher).
Server B is on the same LAN as Server A (on the same rack). I'm considering moving the Distribution database from Server A to Server B to offload some of the processing overhead from Server A.
Are there any gotchas/performance problems associated with having the Distribution database (remote distributor) and the Subscriber on the same server (server B) in a transaction replication topology?
Please advise or point me to the appropriate documentation - I haven't found anything that addresses this specific question...thanks in advance,
Smitha

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

We are going away from a 2003 Windows Server OS with SQL Server 2008 R2 to a 2012 Windows Server with 2012 SQL Server. Both the distributor and subscriber resides on 2003 Windows Server and the focus will be to migrate those databases to the 2012 SQL Server.
 We would also like to avoid sending down a new snapshot due to logic in the replication process (major headache to clean up data).  what's the best approach in moving the distributor and subscriber databases without having to run a snapshot? Â
In theory and needs testing:
1. Work with business users to get downtime
2. Stop sql apply so no new changes are going to the Oracle publisher database
3. Remove subscription, publication and distributor from current replication
4. Oracle DBA to clear out replication related objects - fresh clean slate
5. Use log shipping to apply last t-log and restore db with Keep_Replication
6. Set up new distribution, publication (keep existing object unchanged), and subscriber (without initialization) Will this work?

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.

I have replication setup between our main site and a remote one, and have recently noticed that the database at the remote site's .MDF file is about 3 times as large as the main site's. This doesn't seem to make sense since essentially all of our data is replicated between the two servers. Can anyone suggest why this might be happening and what is safe to do to shrink the remote file?
TIA

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.

Hi Nerds
There are 2 production servers (SQL Server 6.5). One is publisher and the other one is subscriber. Data is replicated from publisher to subscriber which is a transaction based replication. Each day at 8:00PM data comes into publisher and the updations,replication,backup,reporting are carried out till 11:00AM next day. The subscriber server is used as a reporting server and the publishing server is used as the data warehouse server.
I want to cleanup a table on the publisher. Since it is replicated on the subscriber, can I do delete operation on the subscriber, make the subscriber server a publisher and the publisher server a subscriber, do replication from publisher(new) to subscriber(new) and again change publisher to subscriber and subscriber to publisher without affecting the production line of the databases. I have to do this between 11:00AM to 8:00PM.
Pranav.

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 Everyone,
I plan to do transactional replication. The publisher/distributor is sql2005 and subscriber is sql 2000. Is that possible. Because When I setup subscriber, I keep getting "The directory service is currently unavailable" in finding sql server replications.

Hi,I'm trying to setup replication using SQL 2000 as the publisher and SQL 2005 as the subscriber.The problem I have is that the SQL 2000 instance is running on a non standard port 1083, so the name of the instance I'm connecting to is: TESTPC1SQL2000,1083SQL 2005 requires you to provide the "requires the actual server name" which would be "TESTPC1SQL2000" which unfortunately will not work as it's on a different port.The error message I'm getting when attempting to setup the subscription on SQL 2005 Management Studio is this:TITLE: Connect to Server------------------------------Cannot connect to TESTPC1SQL2000,1083.------------------------------ADDITIONAL INFORMATION:SQL Server replication requires the actual server name to make a connection to the server. Connections through a server alias, IP address, or any other alternate name are not supported. Specify the actual server name, 'TESTPC1SQL2000'. (Replication.Utilities)Does anyone know a workaround to this?Thanks,Andy

I want to have transactional replication setup with SQL 2000 as a publisher and SQL Express 2005 as a subscriber? Where can I get some documentation around that?
Basically, the problem I am stuck with is that while registering the subscriber in SQL2000, SQL2000 cannot recognize my SQL Express 2005 instance as a subscriber. I have tried both SQL Ent. Mgr. and sp_addsubscription.
Please help.
Thanks,

According to BOL, you can initialize a transactional subscriber by restoring the Publisher's backup to the Subscriber DB. But any timestamp columns must be converted to binary(8) and indexed views must be converted to tables. But are there other things you must do? What about identity columns? Triggers?
Thanks
