Log Buffer #453: A Carnival of the Vanities for DBAs

Posted in: Log Buffer, Technical Track

This week, the Log Buffer Edition digs deep into the world of Oracle, SQL Server and MySQL and brings you some of the best blog posts around.

Oracle:

  • Regardless of what type of industry or business you are involved in, the bottom-line goal is to optimize sales; and that involves replacing any archaic tech processes with cutting-edge technology and substituting any existing chaos with results-driven clarity.
  • Oracle Private Cloud Appliance 2.1.1 Released.
  • Every version of the optimizer enhances existing mechanisms and introduces new features, while 12c has introduced some of the most sophisticated transformation to date.
  • PLSQL, syslog and the story of Bolas spiders.
  • Here is why you need to be super careful when using LOB’s within triggers.

SQL Server:

  • Phil Factor talks about late in the day for a DBA.
  • This article details SMKs, DMKs and certificates in SQL Server as they relate to Transparent Data Encryption and Encrypted Backups.
  • In traditional relational schema there can be a lot of one-to-many relationships (e.g. Person may have several phones, or several email addresses).
  • Building Apps for Windows 10 with Visual Studio 2015.
  • The GA of System Center Configuration Manager 1511.

MySQL:

  • rows_examined_per_scan, rows_produced_per_join: EXPLAIN FORMAT=JSON answers on question “What number of filtered rows mean?”.
  • Secure communications is a core component of a robust security policy, and MySQL Server 5.7.10 – the first maintenance release of MySQL Server 5.7 – introduces needed improvements in this area.
  • MariaDB 5.5.47 and updated connectors now available.
  • Google Cloud SQL is a fully managed database service that makes it easy to set-up, maintain, manage, and administer your relational MySQL databases in the cloud. Cloud SQL allows you to focus on your applications rather than administering your databases.
  • A long time ago, libmysqlclient came in two versions: one that was thread safe and one that wasn’t. But that was a long time ago. Since MySQL 5.5, the thread safe libmysqlclient_r library has just been a symlink to the libmysqlclient library, which has been thread safe at least since then.

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.
