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.
