Added a page about my LVC schedule

I get often asked by customers about my schedule, so they can book a class with me. This page now shows my scheduled Live Virtual Classes. I deliver most of my public classes in that format and you can attend from all over the world :-)

How to pass the #Oracle Database 11g OCM Exam

The Oracle Certified Master Exam is among the highest rated exams in the IT industry for a good reason: It is extremely hard to pass!

Unlike most other IT exams that are done as multiple choice tests, the OCM exam means two days of  hands-on practical tasks. No chance you can pass it by just reading books or brain dumps and learning by heart without deep understanding. Without years of practical experience with Oracle database administration – don’t even think about it. Even as a seasoned DBA, you won’t find it easy to pass the OCM exam. Why is that so?

NYOUG Spring General Meeting

The New York Oracle User Group held their Spring General Meeting recently and I was presenting there about the Data Guard Broker and also about the Recovery Area.

Many thanks to the board for organizing this event, I really enjoyed being there! Actually, the Broker demonstration went not so smoothly – always dangerous to do things live – but I managed to get out of the mess in time and without losing too much of the message I wanted to get through. At least that’s what I hope ;-)

Data Guard Logical Standby – what does it mean?

With Data Guard, you have the choice between Physical and Logical Standby databases. Let’s see the differences! My demo starts with a Physical Standby, that is then converted into a Logical Standby (therefore the name of the database):

Brief introduction to ASM mirroring

Automatic Storage Management (ASM) is becoming the standard for good reasons. Still, the way it mirrors remains a mystery for many customers I encounter, so I decided to cover it briefly here.

ASM Basics: What does normal redundancy mean at all?

ASM normal redundancy

It means that every stripe is mirrored once. There is a primary on one disk and a mirror on another disk. All stripes are spread across all disks. High redundancy would mean that every primary stripe has two mirrors, each on another disk. Obviously, the mirroring reduces the usable capacity: It’s one half of the raw capacity for normal redundancy and one third for high redundancy. The normal redundancy as on the picture safeguards against the loss of any one disk.

I’m in the Leadership Circle again :-) That is a quarterly Corporate Award for the best instructors worldwide according to customer feedback.

Exadata Patching Introduction

These I consider the most important points about Exadata Patching:

Where is the most recent information?

MOS Note 888828.1 is your first read whenever you think about Exadata Patching

What is to patch with which utility?

Exadata Patching

Expect quarterly bundle patches for the storage servers and the compute nodes. The other components (Infiniband switches, Cisco Ethernet Switch, PDUs) are less frequently patched and not on the picture therefore.

Impressions from #ukoug_tech14

ACC Liverpool

The Oracle circus went to Liverpool this year for the annual conference of the UK Oracle User Group and it was a fantastic event there! Top speakers and a very knowledgeable audience too, I was really impressed by the quality we have experienced. Together with my friends and colleagues Iloon and Joel, I was waving the flag for Oracle University again – and it was really fun to do so :-)
