Build a SQL Server 2005 Updatable Subscription Replication Topology
SQL Server 2005 has introduced a new replication method called "Updateable Subscription Replication" which allows data modification at both the publisher and the subscriber(s). An option is also available to queue the data from the subscriber so the subscriber does not have to be on the network all of the time. The overall setup is not difficult, but there are a few tricky areas you should be aware of during the setup and configuration. Let's outline setup process in a step by step manner to better understand what is needed in order to make an informed decision about Updatable Subscription Replication in SQL Server 2005.
Can a published SQL Server database be renamed
I have transactional replication configured in production. I am wondering if we could rename the publication database in transactional replication without having to drop and recreate the replication set up. Also, is it possible to rename the database files of the publication database without affecting the replication configuration.
Change Not For Replication Value for SQL Server Identity Columns
When setting up replication there are many things to think about and many options you can choose from when setting up your publications and subscriptions. In most cases replication is an after thought and not part of the original database or application design, so there may be some required changes that need to be done when replication is setup. One of these items is the Not For Replication setting for identify columns.
Customized Alerts for SQL Server Transactional Replication
My company is heavily dependant on SQL Server transactional replication and once in awhile the default alerts are not sufficient and sometimes we want to be able to disable alerts when we perform maintenance. In this tip I will show you a few scripts I have implemented to allow me to better manage our transactional replication.
Determine data latency between Publisher and Subscriber in SQL Server Transactional Replication
I have transactional replication configured in my production environment. It appears the subscriber data is quite far behind from the publisher database. In this tip we look at ways to identify how far behind the subscriber is for replication.
Getting additional error messaging information for SQL Server replication
I recently tested out the install of the third service pack for Microsoft SQL Server 2005. Everything seemed to initially install fine and start up fine once I performed a cursory reboot. However, later in the day an application analyst questioned me about replication problems. Specifically, the existing publication was no longer successfully being published via transactional replication. When reviewing the issue through the Replication Monitor, the error messaging was leaving me wanting more detail to find out why the replication process was failing. So my question is, is there a way to garner more information from the replication agents running via SQL Server Agent?
Handling Data Consistency Errors in SQL Server Transactional Replication
Recently at a client assessment, the chief complaint that every time a "Violation Constraint, Cannot insert duplicate key error...." occurs replication breaks and this causes significant downtime on their production environment. In this tip we cover how to manage these errors without breaking replication.
Initialize SQL Server replication using a database backup
You need to configure transactional replication for a very large SQL Server database. Instead of running the snapshot agent to initialize the subscriber, in this tip we look at how you can initialize the subscriber from a SQL Server backup.
Introduction to SQL Server Heterogeneous Replication
One of my clients contacted me about replicating data to non SQL Server databases. My client has a new business partner whose application runs on an Oracle database. Part of the business deal is to replicate data between the two environments. We are already using SQL Server to SQL Server replication and in this tip I cover some of the options available to replicate data between SQL Server and non SQL Server databases.
Limit snapshot size when adding new article to SQL Server replication
I have transactional replication configured in my production environment. The business has requested that I add a new article to the publication. I would like to initialize only the new article added to the publication, so that I could avoid taking a total snapshot of all existing articles in the publication. In this tip we cover the steps need to achieve this.
Maintain Custom Indexes on Replication Subscriber Tables via Pre and Post Scripts
We are using replicated Subscriber databases for reporting and other purposes in our environment. As such, we have differing index needs based on the user activity on the publisher tables vs. the subscriber tables. Unfortunately, whenever we reinitialize replication, we have missing indexes on the tables. Since the index needs are different between the publisher and subscriber, I do not also want to replicate all indexes from the publisher using the schema options that I wrote previously. How can I address these issues? Check out this tip for a detailed explanation.
Maintain SQL Server Replication using Source Control
My company relies on replication intensively and we have many different SQL Server versions and configurations to support. For example, some publications are replicating data every minute, some continuous and others on demand. In addition, we have several replication articles with different schema options due to the requirements on the subscriber. Therefore, we wanted to be able to manage the configuration in a Source Control system. In this tip we look at how this can be done.
Monitor SQL Server replication latency using tracer tokens
Moving database files for a replicated SQL Server database
I am running out of disk space for one of my SQL Server replicated databases. I would like to move the database files of my publication database, which is part of transactional replication, to a drive on the same server, which is has more free space. Which is the better option for moving the files without impacting the transactional replication: sp_attach_db/sp_detach_db or alter database modify file? Check out this tip for the solution.
Options to not replicate SQL Server DELETE commands
I have transactional replication configured in my production environment. The business team has requested that I do not replicate delete operations on certain articles. In this tip we look at a couple of options to not replicate DELETE commands.
Options to reinitialize subscriptions in SQL Server replication
I have transactional replication configured in my production environment with multiple subscribers. The business team has requested that one the subscriptions be reinitialized, because they think there is some missing data. In this tip we look at the different options that you can use to reinitialize a subscription for transactional replication.
Overview of Peer-to-Peer Transactional Replication in SQL Server 2008
Peer-to-peer replication can help scale out an application and implement high availability and in this tip we look at an overview of P2P replication.
Replication Schema Option Across Different Versions of SQL Server
My company uses replication quite extensively across SQL 2000, SQL 2005 and SQL 2008 servers. The problem with using different versions of SQL Server is that the replication options do not always behave the same way. Because of these differences we have stopped using SQL Server Management Studio and Enterprise Manager to setup replication. Also we have taken the time to look at the schema options for replication to make sure the end result is the same for all versions of SQL Server. In this tip we take a closer look at schema options for replication.
Replication support only option with SQL Server 2005 replication
When setting up transactional replication with SQL Server 2000 there were only two options for getting your subscribers the data and the objects necessary for replication. The first option was "none" which meant you had to do everything manually and the second option was "automatic" which did everything from creating the tables, creating the stored procedures needed for replication and synchronizing the data. SQL Server 2005 now offers two new optoins "replication support only" and "initialize with backup".
Space Impact of Replication Snapshot Agent Job in SQL Server
I have noticed that available disk space on my SQL Server is getting low and I see a number of files getting generated in the replication snapshot folder. Because of these files there is a space issue on my server. Why are these files here and what can I do to resolve this problem?
SQL Server 2005 Peer to Peer Replication
SQL Server 2005 has a lot of new features and sometimes these new additions are overlooked as a new way of configuring and managing your SQL Server environment. One of these new features is Peer to Peer transactional replication. With Peer to Peer replication certain tasks are made much simpler, because all nodes act as both a publisher and subscriber.
SQL Server Replication Scripts to get Replication Configuration Information
My company uses SQL Server replication for moving data between servers and we have several publications with many articles being replicated. Therefore, I get questions all of the time about what tables are being replicated, what databases are published, what servers are subscribers, etc... This information can be pulled using SQL Server Management Studio, but it takes a long time to do manually since there are so many properties for each publication. In this tip I will show you three basic scripts that I use to help answer these questions.
SQL Server snapshot replication fails when importing data from the distributor
Snapshot replication fails when trying to import data from the distributor. You get an error message similiar to "Could not bulk load. The sorted column 'rowversion' is not valid. The ORDER hint is ignored." In this tip I go over a solution to fix these issues.
Steps to Rename a Subscriber Database for SQL Server Transactional Replication
I have transactional replication configured in production. The business team has a requirement to rename the subscription database. Is it possible to rename the subscription database and ensure that transactional replication will continue to function as before. In this tip we cover the steps.
Transactional Replication Snapshot Issues in SQL Server
SQL Server replication has been around for quite some time. One of the issues that you are faced with when setting up transactional replication is getting your subscribers all of the initial data prior to replicating new transactions. When doing transactional replication in SQL Server 2000 from SQL Server to SQL Server the default snapshot process uses the native method which locks the table that is being replicated until the entire snapshot is complete. Depending on the size of the table this could take some time and therefore block other processes trying to access the table until the snapshot is complete. So how can you get around this problem?
Troubleshooting Slow SQL Server Replication issue due to Distributor Database Growth
My company has a very replication intensive environment (mostly transactional replication) and recently I started to see that replicating data was taking longer and longer. In this tip I will show you some of the techniques that I used to troubleshoot the issue as well as what the final resolution was.
