OTN APAC 2014 : Auckland to Birmingham

Everything went smoothly at Auckland airport. Boarding an A380 takes quite a bit of time and I was near the front of the plane, so I was in the last group to board. Fortunately there was loads of room for hand luggage and the seat was pretty good. The people too my right were a […]

New leafmisscount Option in Flex Cluster 12c

In the Oracle RAC previous version we have worked with the option “misscount” of crsctl, which applies for all the servers because there was only one kind of servers, but in the new version of Oracle (12c) we have a new kind of RAC configuration, the “Flex Cluster”. With Flex Cluster we have two kinds of servers “Hub nodes”…

Challenge Me! Capturing SQL Server Data with PowerShell

Hello PowerShell lovers! If you are reading this blog post, then you are likely interested in attending my session at SQLBits (well, so far it is an abstract. Hopefully I will be selected!) Any data professional who is responsible for performance tuning, has their way of gathering data to troubleshoot and solve issues. But what…

KeepAlive socket in 12c listener

A not uncommon issue with firewalls and listeners are timeouts. Your production database may be behind a firewall, you may connect from a remote location, even your Windows workstation may have some firewall activated, possibly you use ssh tunnels or TCPS. All those occasionally lead to timeouts and connection abortion, for instance ORA-03113 end-of-file on […]

Parallel Costs

While creating a POC of a SQL rewrite recently I received a little surprise as I switched my query from serial execution to parallel execution and saw the optimizer’s estimated cost increase dramatically.

OTN APAC 2014 : Auckland – Day 2

Look What We Made

As a team-building activity for our newly merged team of research, design and development, someone, who probably wishes to remain nameless, organized a glass mosaic and welding extravaganza at The Crucible in Oakland. We split into two teams, one MIG welding, the other glass breaking, and here’s the result. Original image, glass before firing. Finished […]

I got a bunch of emails this morning telling me by blogs had upgraded to WordPress 4.0.1. It’s a critical security release, so if you’ve not done an auto-update, you really need to get this sorted. The downloads and changelog are in the usual places. Cheers Tim…
