    I would like to setup replication between production server and a development server.  At the same time, I would like to be able to add a row of data to the development server and not have that data overwritten when the replication takes place. 

    Is there a way to accomplish this?

    On one particular subscriber (out of 40+), an error was throw that there were no available identity ranges.  In debugging, it was found that this particular subscriber had allocated ranges for all articles 800+ times over the course of a few days by examining msmerge_identity_range_allocations thereby using all int values.

    I'm trying to figure out why this happened.  Perhaps since all articles for this publication exhibited this issue, the subscription was marked for reinitialization and it was never able to complete but allocated new ranges for the articles and didn't remove those allocations upon not being able to complete all actions.  There do not seem to be any hints in the SQL Error logs to help my debugging process. 

    Has anyone else seen an issue like this?  If so, how did you correct it or at least determine root cause?

    Hi All,

    Current scenario: Site 1 (Publisher DB) --> Site 2 (SubscriberDB) -- Transactional replication is setup

    Now,we need to add another subscriber at Site 3. 

    We plan to initialize the 2nd subscriber using a Backup. (http://msdn.microsoft.com/en-us/library/ms151705(v=sql.90).aspx). Currently, allow_initialize_from_backup is already set  to 1.

    While adding new subscriber, I plan to DISABLE DISTRIBUTOR CLEANUP JOB temporarily to prevent removal of transactions from the distribution database. 

    Further, we need to setup a filtered replication from this 2nd subscriber.

    Questions:

    1. Is there a downtime (even a small one) needed during this initialization using backup?

    2. What other risks are seen during this kind of setup?

    3. If I use the steps at http://msdn.microsoft.com/en-us/library/ms147834(v=sql.90).aspx to add the subscriber,
    it will by default create a push replication, am I correct? (as that is what I want)

    any help is highly appreciated!!

    Thanks.

    What has been people's experience doing this?

    What special changes to Transaction replication Publication or Subscriptions are required?

    Any contra-Indications?

    Thanks

    hello,

    We are looking to set-up replication for our main database and was after some advice on what might and might not work. We are using SQL Server 2008 R2 standard.

    The database is around 130gig in size and the main data table has around 600million rows.  This table has many changes in both updated and additions (I would guess up to 200k updated/additions a day).  It is expected that the database will continue to grow more rapidly in the future.

    We have a remote site that we want to replicate to and our connection to the site is a site-to-site vpn with about a 4meg bandwidth.

    The dream setup would be to put in place two-way replication where both databases are editable and I can choose to use either database.  The performance of the Master database could not afford to be significantly impacted while the secondary performance would not be as critical.  It would also be good if whatever setup is used could be later expanded to include additional target sites.

    Based on the very little information that I have provided can some provide advice on 1. is this possible and 2.  what is the best technologies and setup that I would likely be used.

  • 07/25/13--00:02: Replication Failover
  • Hi,

    Can anybody tell me the fail-over procedure in all types of replications?

    For example: if Publisher/Distributor/subscriber is down?

    We have a merge replication between 2 servers. We will have a maintenance on one server and would like to stop all the replications. How to stop it? Do I need to stop the SQL agent?

    Recently we encounter some errors on the log reader agent job for all our publishers in our push replication setup.  All publisher dbs are coming from the same db in the publishing server.    Our distribution db is on its own physical box.  We are using SQL 2008 r2.  The first error is related to“The process could not execute 'sp_replcmds' .  The second one is "Could not obtain information about Windows NT group/user 'domain\xxxxxx', error code 0x5”.    The strange thing about the second error is that we don't use that account to set up the replication.  I am using a totally different account for it.  Just in case, I checked all log reader security set up for the publisher dbs and it is using the sql job agent account by impresonation and not using the said domain account in the error.  Another interesting about this problem is that the problem would self-correct meaning after a few hours of giving out the errors, the log reader would function again and distributing the commands to the distrbution db.    

    I need to find out why the replication is giving out an error on a domain account that we don't use.    A little bit of background info here.  We did move all our servers to a different location and set up a new domain for everything.  However, all replication setup started from scratch so there is no chance I would use the said account to set up my replication.    the only thing that is coming from the old location (or old domain) is the databases.    We did a backup and restore to bring the databases to the new location but we don't restore the original publisher settings during the restore.

    Is it possible that somehow there is some old replication setting related to the said domain account somewhere in our current replication setup somewhere?  Is there a command I can use to search for this domain account in our replication setup?  Any ideas or thoughts are very much appreciated.

  • 07/25/13--23:22: Replication of the database
  • I have Replicated live database 'db1' from server 1 to database 'db2' of server 2. It got replicated correctly.

    Hi All,

    we have a transactional replication , suddenly subscriber database was down... on that time my distribution database size was grow irregular , i have try to shrink the distribution database size and tacking the log backup also but it's not working .. still distribution database size was growing .

    currently subscriber database was up and running fine but still i am facing the above problem.

    In this situation how to troubleshoot the issue?

    We have configured the distributor on SQL Server 2012 and we were able to create a publication on another server running SQL 2008 R2 until recently.  Now were getting this error message when we tried to configure the remote distributor on the publication server.  NOTE: the password is correct and has been doubled checked.

    We are replication 2008 db to 2012 instance. - Thanks Norm

    Title: Configuration Distribution Wizard

    SQL Server could not connect to the Distributor using the specified password. 

    Connection to server failed.

    OLE DB provider "SQLNCLI10" for linked server returned message "Login timeout expired".

    OLE DB Provider "SQLNCLI10" for linked server returned message "A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections.  For more information.......

    We have configured SQL 2012 Server Database Transaction Replication for our client's .NET Web application to distribute SQL transaction and reporting on different SQL servers. 

    We had implemented transaction replication on to SQL-Node1 is working as Master DB Server, We'd configured replication of Master DB on SQL-Node2 to pull out reports in to our web application which having lots of transactions and data uploading from excel sheet entries around 10 million entries each day. 

    After configured replication on Two SQL 2012 server, after few weeks we facing some performance issues and found some resource get locked during uploading files on to database that's why application unable to access those tables and data. Also found that server performing too much slow during day time when users access our web application.

    Now we are looking to distribute loads on different 3 Nodes of SQL 2012 Servers. Where web application will access and transact data on SQL-Node1, Reporting queries get pull data from SQL-Node2 and SQL-Node3 will be get used to upload excel sheet data on to Database which will get replicated on all other SQL Nodes.

    Current Setup, All Servers having Windows Server 2008 Standard and SQL 2012 Enterprise Edition.

    Database size approx : 15 GB / Replication Used : Transaction / Distributor Role configured on SQL Node1 / Subscriber role configured on SQL Node 2.  

    We are looking for solution to resolve above issues which can distribute different loads (reporting, data uploading, transaction) and replicate data between all SQL Nodes.

    Which feature will do perform well for above scenario among SQL 2012 HA, SQL Replication or SQL Mirroring ??

    Quick response will be highly appreciated.

    Hi,

       I'm working on SQL 2012. My OS is Windows 2008. When I created a publication for a replication transaction, snapshot agent failed as below error:

    "A .NET Framework error occurred during execution of user-defined routine or aggregate "sp_scriptdropinsreconciliationproc_sqlclr":
    System.TypeInitializationException: The type initializer for 'System.Data.SqlClient.SqlConnection' threw an exception. ---

    ".

    Could you help me to resolve this issue ?

    Thanks

    Hi All,

    I have faced issue regarding stored procedure.

    actually  my application team ran the stored procedure regular basics (contain some inserts)  ,,every day it take 20 mins for executing but today it's tacking the more than 2 hours (still it's running) . 

    i have checked the which they are inserting and ran the updated statics also,i have checked  and fixed the table fragmentation and indexes related issues but still it's tacking the logtime for executing .

    what is the recompile ?

    how to resolve the slow running stored procedure?

    Please post the your valuable ANS ASAP.

    Thanks in Advance.

    How it is possible.


    Thanks
