Quick Data Synchronization Using Table Partitioning and SSIS
Synchronizing massive amounts of data between heterogeneous environments can be painfully slow if SQL Server doesn’t provide a replication publisher. You can significantly reduce the time it takes by using SQL Server Integration Services (SSIS) and table partitioning.
Build a Policy-Based Management System for SQL Server 2008
Deal with the limitations of SQL Server 2008’s built-in policies by creating a table-driven solution that lets you insert policy exceptions and regulate policy execution.
Partitioning a Table that Contains Future Dates
If you have a large table with future dates in it, you can use the method described here to partition it.
Solving Merge Replication Performance Problems
Pointing LAN and mobile users to different instances of an application database on different servers helped one organization improve performance for LAN users without major application or database changes.
Steps for Configuring Publications
Use these steps to configure publications for merge replication.
Merge Replication in the Real World
If you're looking for an easy-to-use solution for your organization's high-availability and disaster-recovery needs, this real-world example can help you decide whether merge replication is a good choice for you.
Creating a DTS Package to Run Forced Replication
If you're using forced replication to synchronize a large number of tables, you can create a DTS package to run the replication process.
Handling Referential Integrity
If you have tables that are related to each other with foreign key constraints, running forced replication might disrupt the referential integrity of Subscribers. You can avoid problems by using the NOT FOR REPLICATION option.
Synchronizing on Demand 4
Transactional replication helps maintain data availability, but if data becomes unsynchronized, you might not be able to quickly synchronize by using conventional techniques. You can synchronize selected data on the fly--without disrupting business.
Additional Facts About Configuring Transactional Replication 6
Many DBAs don't know how rich a tool they have in transactional replication. Here are some of the options you can use when setting up replication.
7 Steps to SSL Encryption 1
Information about setting up server-requested SSL encryption in a clustered SQL Server environment is hard to come by. But these clear steps pave the way to a straightforward implementation.
CA Basics
To enable SSL encryption on your system, your server and clients must have a digital certificate from a Certificate Authority (CA). Here is some basic information you should know when you're ready to request a certificate.

A Replacement for Maintenance Plan Backups

This blog post is a bit of a ‘repeat’ – since I already covered much of the rationale behind this post in Part 23 of my multi-part series on AlwaysOn Availability Groups and SQL Server Agent Jobs. But, I also figured that this is enough of an important topic to merit its own blog post....More

Looking forward to Containers

Virtualization has long been a staple when it comes to computing. In essence, virtualization is really just the use of abstraction to make things either easier to manage or more fault-tolerant. Disks, for example, have long been virtualized in the sense that a single, physical, can easily be divided up into multiple logical (or virtual) volumes (or drives) just as easily as a number of discreet physical disks can also be virtualized into a single drive (via RAID) – which can further be partitioned into volumes, LUNs, and so....More

AlwaysOn Availability Groups and SQL Server Jobs, Part 29: Practical Implementation Tips

My initial goal in writing this series of posts was to outline some of the concerns surrounding Availability Groups (AGs) and SQL Server Agent Jobs – and call out how there is virtually no guidance from Microsoft on this front and then detail some of the pitfalls and options available for tackling this problem domain. I initially expected this series of posts to have between 25 and 30 posts – according to some of the early outlines I created ‘way back when’....More
