At the time of writing this post, Oracle Forms 11g installations are configured by default to work with a specific JPI (Java Plug-In) version: 1.6.0_12. You can verify this by checking your formsweb.cfg file: grep jpi-version formsweb.cfg #jpi_mimetype=application/x-java-applet;jpi-version=1.6.0_12 Unfortunately, it seems Firefox is very particular when it (more...)

Chapterhouse Dune is the last in the Dune series by Frank Herbert.

It’s really hard for me to make a judgement about Chapterhouse: Dune. On the one hand there are some excellent characters and the general story line is great. On the other, there are parts I found really boring. (more...)

How do you want to start the day? I’m guessing it’s not to be called out to the front of the room by a speaker and used as a guinea pig, while they ask you trick questions to make you look stupid. Tom Kyte, you will pay. Oh yes! You will (more...)

So Day 1 (part 2) didn’t go to plan because I forgot to take my camera or my phone to the party.

Suffice to say, lots of food, lots of drink (for those that do) and most importantly lots of dancing. Yes, I once again murdered the traditional dances of (more...)

A very tricky and interesting situation came-up this morning while configuring one of the standby databases of over 1.5TB sized . Whilst the database is being cloned to the DR site as part of the DUPLICATE..ACTIVE DATABASE command, which actually took more than 1.5 day, a couple of (more...)

A couple of weeks ago, Kevin released the second version of SLOB – the Silly Little Oracle Benchmark. Readers will know that I was already a big fan of the original version, but version 2 (which I was fortunate enough to test prior to its release) now has extra features (more...)

Last night we all got together to eat some food and chat. Julian Dontcheff is practically a savant where Bulgarian Poetry, World Cup match results and random Oracle facts are concerned. Although Christian Antognini was pretty impressive on the random Oracle facts too.

I didn’t have any presentations today, so (more...)

The call for papers is open for Tech 13 – the “server-side” conference of the UKOUG.

The conference was getting so big that we’ve split Apps from Server Tech and will be running the two conferences separately this year. The Server Tech conference will be in Manchester from 2nd to (more...)

Cloud computing has grown from merely an IT trend to an essential technological initiative that is driving a competitive advantage for many enterprises. However, it has become clear from recent research that on the whole, firms are not effectively deploying these solutions. This means that in order to gain more (more...)

Installation and use.

So, (more...)

Flashback database is not enabled by default so first step would be to enable it. When enabled a process RVWR (Recovery Writer) copies modified blocks to flashback buffer. Later this buffer (more...)

Enterprise Manager Cloud Control 12c is mostly a better product than the 10g version we were using before.  But I am getting really frustrated with the Explain Plan functionality.

A big part of my job is performance tuning and monitoring running SQL.  And to do that you need (more...)

With the emergence of IT trends such as cloud computing and mobility, enterprises have realized that previous security efforts are inadequate for mitigating the new risks that come with these technologies. While looking to upgrade the security infrastructure, firms are may need remote database support to ensure improvements in data (more...)

I often use "ssvnc" to connect my servers to install or do something about X. Anyway, I must to start VNC before by using "vncserver".

In my last post about large pages in 11.2.0.3 I promised a little more background information on how large pages and NUMA are related.

Background and some history about processor architecture
