Log Buffer #436: a carnival of the vanities for DBAs

Posted in: Technical Track

This Log Buffer Edition covers the top blog posts of the week from the Oracle, SQL Server and MySQL arenas.


  • Momentum and activity regarding the Data Act is gathering steam, and off to a great start too. The Data Act directs the Office of Management and Budget (OMB) and the Department of the Treasury (Treasury) to establish government-wide financial reporting data standards by May 2015.
  • RMS has a number of async queues for processing new item location, store add, warehouse add, item and po induction. We have seen rows stuck in the queues and needed to release the stuck AQ Jobs.
  • We have a number of updates to partitioned tables that are run from within pl/sql blocks which have either an execute immediate ‘alter session enable parallel dml’ or execute immediate ‘alter session force parallel dml’ in the same pl/sql block. It appears that the alter session is not having any effect as we are ending up with non-parallel plans.
  • Commerce Cloud, a new flexible and scalable SaaS solution built for the Oracle Public Cloud, adds a key new piece to the rich Oracle Customer Experience (CX) applications portfolio. Built with the latest commerce technology, Oracle Commerce Cloud is designed to ignite business innovation and rapid growth, while simplifying IT management and reducing costs.
  • Have you used R12: Master Data Fix Diagnostic to Validate Data Related to Purchase Orders and Requisitions?

SQL Server:

  • SQL Server 2016 Community Technology Preview 2.2 is available
  • What is Database Lifecycle Management (DLM)?
  • SSIS Catalog – Path to backup file could not be determined
  • SQL SERVER – Unable to Bring SQL Cluster Resource Online – Online Pending and then Failed
  • Snapshot Isolation Level and Concurrent Modification Collisions – On Disk and In Memory OLTP


  • A Better Approach to all MySQL Regression, Stress & Feature Testing: Random Coverage Testing & SQL Interleaving.
  • What is MySQL Package Verification? Package verification (Pkgver for short) refers to black box testing of MySQL packages across all supported platforms and across different MySQL versions. In Pkgver, packages are tested in order to ensure that the basic user experience is as it should be, focusing on installation, initial startup and rudimentary functionality.
  • With the rise of agile development methodologies, more and more systems and applications are built in series of iterations. This is true for the database schema as well, as it has to evolve together with the application. Unfortunately, schema changes and databases do not play well together.
  • MySQL replication is a process that allows you to easily maintain multiple copies of MySQL data by having them copied automatically from a master to a slave database.
  • In Case You Missed It – Breaking Databases – Keeping your Ruby on Rails ORM under Control.

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.
