This Friday Steve Jones wants to know if innovation matters in your company. And if you really enjoy working with computers and solving problems.
Microsoft IT protects against unplanned Transactional Replication outages and issues by using best practices and proactive monitoring. This results in increased stability, simplified management and improved performance of transactional replication environments.
In a previous tip on Monitor Your SQL Server Virtual Log Files with Policy Based Management, we have seen how we can use Policy Based Management to monitor the number of virtual log files (VLFs) in our SQL Server databases. However, even with that most of the solutions I see online involve the creation of temporary tables and/or a combination of using cursors to get the total number of VLFs in a transaction log file. Is there a much easier solution?

We often view potential hires based on their potential and not necessarily on their experience. Today Steve Jones talks about the dangers of putting more emphasis on future, rather than past, performance.
Unless you are working on a reporting-only application you will probably need to update tables in your SQL Server database. To update rows in a table you use the UPDATE statement. In this level we will be discussing how to find and update records in your database, and discuss the pitfalls you might run into when using the UPDATE statement.
As the SQL Developer community grows to embrace the benefits of test-driven development for databases, so the importance of learning to do it properly increases. One way of learning effective TDD is by the use of code kata – short practice sessions that encourage test-first development in baby steps. I have a limited number of licences for SQL Test to give away free – just for practicing a bit of TDD and telling me about it.
As you know, SQL Server databases and backup files can take up a lot of disk space. When disk is running low and you need to troubleshoot disk space issues, the first thing to do is to find large files that are consuming disk space. In this article I will show you a PowerShell script that you can use to find large files on your disks.
Once again Jonathan Lewis (Oracle Ace Director, OakTable Network) and Grant Fritchey (Microsoft SQL Server MVP) will host a live discussion on Oracle and SQL Server, this time in relation to temporary tables. Will they agree on some common ground? Or will it be an out and out argument? Either way, be prepared for a lively exchange that will not only entertain, but will teach you key concepts on Oracle and SQL Server.
