Last week I was in London to attend the UK Oracle User Group licensing event. After a number of sessions with excellent material leading to very interesting discussions (one was showing – with permission – some of my own content, with the comment that it saved this customer “a shitload [...]
Virtualizing databases has huge financial and operational benefits – in particular with Oracle, where physically deployed database servers are typically heavily under-utilized which leads to huge over-spending on license cost.
Of course poor efficiency on database servers leads to higher processing requirements, to higher number of CPUs purchased, and in turn [...]
Infrastructure has always been a tough place to compete in. Unlike applications, databases or middleware, infrastructure components are fairly easy to replace with another make and model, and thus the vendors try to show off their product as better than the one from the competition.
In case of storage subsystems, the [...]
Sometimes I hear people claim that by using faster storage, you can save on database licenses. True or false?
The idea is that many database servers are suffering from IO wait – which actually means that the processors are waiting for data to be transferred to or from storage – and [...]
A while ago Kevin Closson announced a new release of the well-known SLOB kit.
SLOB is a simple but powerful toolkit that drives lots and lots of IO on a real Oracle database (so for performance testing of database platforms, it’s much better than synthetic IO tests).
A previous version was bundled [...]
