Speaker(s)Michelle Poolet, Michelle Poolet

Duration: 60 minutes

Track: Strategy and Architecture

Are your transaction logs ballooning? Are the VLF numbers out of control? What can you do about it? 

Let's start with "what's a VLF and why do I care?" and move forward into learning how to shrink VLFs (a temporary solution) and how to resize SQL Server transaction log files (a more permanent solution) for greater server stability, better performance during server startup, backups, and restores, and to minimize storage space requirements.

The SQL Server transaction log is a critical piece of SQL Server's ability to ensure that data is maintained exactly as the user input or modified the data. The transaction log must, at times, grow in size in order to do its job. When a transaction log’s growth gets out of control (too large, too many segments), then SQL Server’s ability to perform as it should is negatively impacted. Too-large transaction log files cause longer database start up, backup and restore times, and will require more storage space on disk. Learn how to control VLF gro
