Log Buffer #424: A Carnival of the Vanities for DBAs

Posted in: Technical Track

This Log Buffer Edition covers various valuable blog posts from the fields of Oracle, SQL Server and MySQL.

Oracle:

  • Oracle Big Data Appliance X5-2 with Big Data SQL for the DBA.
  • Loading, Updating and Deleting From HBase Tables using HiveQL and Python.
  • In keeping with the ODA quarterly patching strategy, Appliance Manager 12.1.2.3 is now available.
  • From time to time someone publishes a query on the OTN database forum and asks how to make it go faster, and you look at it and think, “it’s a nice example to explain a couple of principles because it’s short, easy to understand, obvious what sort of things might be wrong, and easy to fix.”
  • Optimizing the PL/SQL Challenge IV: More OR Condition Woes.

SQL Server:

  • Will RDBMs be obsolete? Should Data Professionals care about Big Data technologies? What is NoSQL? What is Hadoop?
  • In a development team, there are times when the relationships between developers and testers can become strained. How can you turn this potential conflict into something more positive?
  • Michael Fal is a huge advocate of automation and many ways it can improve the lives of developers and DBAs alike, but you can’t just automate all your problems away.
  • One way to handle a very complex database project with several databases and cross references.
  • Building the Ideal VMware-based SQL Server Virtual Machine.

MySQL:

  • Optimizing Out-of-order Parallel Replication with MariaDB 10.0.
  • General-purpose MySQL applications should read MySQL option files like /etc/my.cnf, ~/.my.cnf, … and ~/.mylogin.cnf. But ~/.mylogin.cnf is encrypted.
  • Creating and Restoring Database Backups With mysqldump and MySQL Enterprise Backup.
  • If you don’t know much about bash shell, you should start with the prior post to learn about bash arrays.
  • Installing Kubernetes Cluster with 3 minions on CentOS 7 to manage pods and services.

About the Author

I have been in love with Oracle blogging since 2007. This blogging, coupled with extensive participation in Oracle forums, plus Oracle related speaking engagements, various Oracle certifications, teaching, and working in the trenches with Oracle technologies has enabled me to receive the Oracle ACE award. I was the first ever Pakistani to get that award. From Oracle Open World SF to Foresight 20:20 Perth. I have been expressing my love for Exadata. For the last few years, I am loving the data at Pythian, and proudly writing their log buffer carnivals.
