In their words: “…here are a handful of very important lessons you will have to learn if you administrate a SQL Server.”

SQL Server defaults configuration settings can hurt you

  • Auto-grow and Auto-shrink
  • Number of database files (trace flag 1117 and 1118)
  • MaxDOP and Cost Threshold for Parallelism
  • Max and Min Memory
  • Optimize for Ad Hoc Workloads

Preventative maintenance (PM) requires DBA attention

  • SQL Agent Error Notifications
  • Database consistency checks (DBCC) on user db’s
  • Backups with verification & Restore test
  • Defragmentation (Fill factor, Pad Index)
  • Updating Index Statistics (trace flag 2371)

Make sure indexes are working properly

  • Object-relational mapping tools do horrible things to and with indexes
  • Every table should have a clustered index and NOT A GUID!
  • Sequential ID field is best key and composite keys can be wasteful and slow
  • Be careful about duplicate indexes

Backups, planning, availability and recovery are critical

  • The transaction log is critical for recovery
  • Backups are useless without a restore test
  • Planning is essential!
  • Know your RPO and RTO numbers

Database security is more important than ever and more overlooked than ever

  • SecurityIntelligence.com reports that 75% of threats come from insiders
  • SQL Injection is still the #1 hack that causes real damage
  • Plan ahead of a breach to minimize issues
  • Ensure the least privileges principle for applications running on your servers
  • Don’t assume SA password is safe, especially with vendor purchased apps.

Many, many more SQL Server settings, surprises and solutions are discussed. And I so remember horror stories and wasted hours fixing issues for most of the topics discussed. Right?

I give the webinar: “5 Surprising Lessons Every SQL Server Generalist Has to Learn” a thumbs up!

Note: the webinar goes about 86 minutes and is well worth listening to the entire webinar. Also look at the Q&A tab and resource tab for more information.
