Log Buffer #446: a carnival of the vanities for DBAs

Posted in: Log Buffer, Technical Track

This Log Buffer Edition covers some more Oracle, SQL Server and MySQL blog posts from across the world.

Oracle:

  • Should I monitor the MGMTDB database?
  • Connecting MAF Applications to Mobile Cloud Service
  • JRE 6, 7, and 8 now certified with EBS 11i, 12.1, and 12.2
  • The database writer copies data blocks from the buffer cache onto disk. The db_writer_processes initialization parameter determines how many processes will do this task. Its default value is 1 or cpu_count / 8, whichever is greater. I found an Oracle 9 database on a Tru64 server with cpu_count set to 1
  • How To Install Latest Verisign G5 Root Certificates

SQL Server:

  • Dynamic Pivot, Passing Temp Table Variables to Dynamic SQL
  • Oracle offers a results cache in the database (from 11.2 onwards) and in PL/SQL (again, from 11.2 onwards) which can greatly reduce execution time of repeated statements when insert/update/delete activity is not heavy.
  • Maintaining a grouped running MAX (or MIN)
  • Harnessing SQL Server Metadata- Disabling and Rebuilding Indexes
  • Optimizing Your Query Plans with the SQL Server 2014 Cardinality Estimator

MySQL:

  • ClusterControl Tips & Tricks: Updating your MySQL Configuration
  • Become a MySQL DBA blog series – Optimizer Hints for faster query execution
  • Loading Arbitary XML documents into MySQL tables with p_load_xml
  • Use MySQL and Perl to automatically find, follow and unfollow twitter users
  • Great Advice on Monitoring Amazon RDS For MySQL From Datadog

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.
