PowerPoint 2013 Always Starts Minimized

This post has nothing to do with Oracle or Enterprise Manager at all, so if that’s all you’re interested in you can stop reading now. :)

Yesterday I ran into the situation where PowerPoint would only open minimized on the task bar and nothing I could do would get it to budge from there. The only way I could get PowerPoint to start and be displayed on any monitor was to start it in safe mode. [As an aside, to start PowerPoint (or indeed any Office product) in Safe Mode you just need to hold down the Control key while double-clicking either the PowerPoint program or any PowerPoint document.] After starting PowerPoint successfully in Safe Mode, I could see PowerPoint on my screen, but when I closed it down and tried to restart in normal mode, it would always start minimized.

Who Plans The Content of UKOUG Tech15?

When you go to a conference like UKOUG Tech15 there are hundreds of talks given over several days and a dozen or so streams. Who decides what is presented and how do they decide?

12c MView refresh

Some time ago I wrote a blog note describing a hack for refreshing a large materialized view with minimum overhead by taking advantage of a single-partition partitioned table. This note describes how Oracle 12c now gives you an official way of doing something similar – the “out of place” refresh.

I’ll start by creating a matieralized view and creating a couple of indexes on the resulting underlying table; then show you three different calls to refresh the view. The materialized view is based on all_objects so it can’t be made available for query rewrite (ORA-30354: Query rewrite not allowed on SYS relations) , and I haven’t created any materialized view logs so there’s no question of fast refreshes – but all I intend to do here is show you the relative impact of a complete refresh.

Thanks to Leighton Nelson who pointed out  that :

Oracle has a pre-installed Linux VM with 12c

Delphix as well has a pre-installed   trial version

Oracle Exadata Performance: Latest Improvements and Less Known Features

Here are the slides of a presentation I did at the IOUG Virtual Exadata conference in February. I’m explaining the basics of some new Oracle 12c things related to Exadata, plus current latest cellsrv improvements like Columnar Flash Cache and IO skipping for Min/Max retrieval using Storage Indexes:
Note that Christian Antognini and Roger MacNicol have written separate articles about some new features:
