Push And Pull Subscription From Publisher/Distributor?
May 30, 2001
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.
As I understand replication in Sql2K the only difference in push or pull subscriptions is where the agent runs. If I wanted changes in the publisher to be sent to the subscribers immediately after the change then I thought push would be better. But, if I am equally interested in changes made at the subscriber then what should I use? Or does the agent monitor both the publisher and subscriber at the same time?
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?
I AM TRYING TO SET UP A DISTRIBUTOR ON SQL SERVER 2005.
THE LAST STEP WHEN I AM TRING TO CONNECT I GET THE ERROR BELOW:
“ORACLE SERVER INSTANCE 'FOOBAR' CANNOT BE ENABLED AS A PUBLISHER BECAUSE OF THE FOLLOWING ERROR:
ADDITIONAL INFORMATION: UNABLE TO RUN SQL*PLUS. MAKE CERTAIN THAT A CURRENT VERSION OF THE ORACLE CLIENT CODE IS INSTALLED AT THE DISTRIBUTOR. FOR ADDITIONAL INFORMATION, SEE SQL SERVER ERROR 21617 IN TROUBLESHOOTING ORACLE PUBLISHERS IN SQL SERVER BOOKS ONLINE. (MICROSOFT SQL SERVER, ERROR: 21617)�
RESEARCHING THE ERROR IT STATES TO MAKE SURE SQLPLUS IS SET UP CORRECTLY IN THE PATH. THE PATH IS CORRECT. TESTING SQL PLUS IT WORKS; AND I CAN ALSO CONNECT TO THE ORACLE DB IN BUSINESS INTELLIGENCE.
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 setting up  transaction replication in SQL Server 2012 with three individual servers for Distributor, Publisher, Subscriber, But I want to know how to set the folder for Snapshot agent like whether the folder should be a network shared folder or normal local folder.
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?
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.
I'm trying to replicate two very big databases with about 10 million of 4000 characters each. The publisher is SQL 2000, subscriber is SQL 7.0
The subscriber will also perform full text searches.
I'm trying to decide wheter I should use PULL or PUSH. The publisher is operating on a very low quality/speed internet connection, where the subscriber is enjoying a T1.
I am having a problem now. I cannot drop my publisher and publication because i was uninstalled the remote distibutor before i disable al lthe publication. Now the remote distibutor no longer exist.
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?
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
I need to copy a large amount of data from one table and insert it into another table.
The design of the destination table is exactly the same as the source table except for the fact that it has one extra field. Can I copy; in a single SQL statement; all rows in one table (that match given criteria) into another table allowing for the extra field?
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 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
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?
Our current application which uses SQL 2000/CE uses a single Merge publication to populate numerous "read only" tables on the mobile device, and create the schema for a "transactions" table, which will be filled by the mobile device during work, then merged at sync.
Now, the master "transactions" table at the publisher has millions of rows, and the mobile device does not need any of them... so currently we have it "filtering" by a always false clause, so that none of the data is pushed to the client.
The problem with this is that we cannot archive any of the records in the transaction table, as doing so (say, removing 200k rows) would result in the mobile devices (of which there are about 15,000 active in the field) to attempt to reconcile each of those 200k rows when it is next synced, which takes way too long.
Now, what we would like to do is upgrade to SQL 2005/CE 2005, if the new features will allow us a PULL ONLY table in some way? I cannot find how to do this via the wizard, but am sure I am missing something. At least I hope so.
I am not able to connect to Remote Distributor from Publisher using Administrative Link Password. I have configured the Distributor on 1 m/c and Publisher on another m/c. When i use the wizard to configure the publisher using remote distributor. I have also specified the same Admin Password link (distributor_admin) in the distributor m/c. Â I am getting the following message: Â TITLE: New Publication Wizard------------------------------ SQL Server could not connect to the Distributor using the specified password.

SELECT P.Publication ,P.Publication_type ,S.Subscriber_ID ,S.Update_Mode FROM MSPublications P INNER JOIN MSSubscriptions S ON P.Publication_ID = S.Publication_ID
give me publication_type=0. So it is transactional replication but how do we know that is pull or push?
Is there an option to monitor current state of Merge Push Subscription from the Subscriber, without connecting to the Publisher Server? I have examined many SPs and system tables at Subscriber, but didn't find any reliable method...
I've been looking for the right stored procedure to create a push subscription for publication but i haven't had much luck so far. So I was wondering if you guys know which SP is appropriate, that'd be super great!! thanks guys!
note. the sp should run on the subscriber database.
I wonder if anyone has run into this problem before.
I have inherited a SQL Server 2000 box with what appears to be a push subscription set up on it. However, the original Subscription database has long since been removed, leaving that box with what is essentially an orphaned push subscription.
We are trying to remove the subscription, but do not understand how. All documentation I have found keeps insisting that this be done at the subscriber database (which is for all effective purposes, destroyed).
We have created replication from one production server to another backup server by using SQL scripts. These scripts have been generated by SQL Server after manual initial setup. When I ran these scripts they did not add the subscription for the backup server because a stored procedure were missing named something like sp_addsubscription. Therefore I ran the script on the production server and created the subscription manually on the backup server. But I made an error, I created a push subscription first but I should have created a pull subscription. Now I can't delete the push subscription. I don't even get a error message. I can't press delete and when right clicking on it I can only choose Help. The subscription has the following properties:
Type: push Status: retrying Last action: The process could not connect to distributor 'PSERV' Replication type: Snapshot
Anyone know how I can delete this push subscription on my backup server?
I am using SQL 2000. How can I get my transactional replication reinitialized after it has failed with several attempts.
I know one way of doing it through enterprise manager and specifying the subscription to reinitialize. But this will apply the snapshot and will take long time.
in the clustering lab I was setting up transact replication - created the publication ok, but when I setup the subscription, wasn't sure what account it needed to use :/Â tried various formats of Administrator and Password;1 etc - but no dice. what account I need to be using?
