Hochkarätige Referenten zum Thema Oracle Database 12c – Jetzt!

Wie und warum Sie jetzt auf 12c kommen sollten erläutern wir in sieben Webinaren von je einer Stunde Dauer. Die Webinare finden an jeweils verschiedenen Tagen statt, beginnend am 11. August, wo Mike Dietrich zum Thema Upgrade (natürlich) vortragen wird.

Einfach anmelden und bequem und kostenlos informieren – das ist doch ein unschlagbares Angebot, oder? Finde ich auch :-)

Transport Tablespace using RMAN Backupsets in #Oracle 12c

Using backupsets for Transportable Tablespaces reduces the volume of data you need to ship to the destination database. See how that works:

RMAN TTS on the source database

The tablespace is made READ ONLY before the new BACKUP FOR TRANSPORT command is done. At this point, you can also convert the platform and the endian format if required. Then on the destination site:

Table Recovery in #Oracle 12c

You can now restore single tables from backup! It is a simple command although it leads to much effort by RMAN. See it as an enhancement over a ‘normal’ Point In Time Recovery:

After a full restore from a sufficiently old backup, archived logs are being applied in direction of the presence until before the logical error. Then a new incarnation comes up (with RESETLOGS) and the whole database is as it was at that time. But what if it is only a dropped table that needs to be recovered? Enter the 12c New Feature:

Multisection Backup for Image Copies

A nice Oracle Database 12c New Feature enhances the multisection backup, introduced in 11g: You can use it now for image copies also!

What happens to the Standby when you move a datafile on the Primary?

In 12c, we have introduced online datafile movement as a new feature. Now does that impact an existing standby database? I got asked that yesterday during an online webinar. My answer was that I expect no impact at all on the standby database since redo apply doesn’t care about the physical placement of the datafile on the primary. But I added also that this is just an educated guess because I didn’t test that yet. Now I did:

I love Live Demos – how about you?

Tired of boring slide-shows? Join me for free to see Oracle core technology live in action!

Live demonstrations have always been a key part of my classes, because I consider them one of the best ways to teach.

This is your opportunity to have a glimpse into my classroom and watch a demo just as I have delivered it there.

Apparently, not many speakers are keen to do things live, so the term Demonar (Demonstration + Seminar) waited for me to be invented :-)

A positive effect towards your attitude about LVC and Oracle University Streams with its live webinars is intended, since the setting and platform is very similar there.

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 ;-)
