"You see, to tall men I'm a midget, and to short men I'm a giant;
to the skinny ones I'm a fat man, and to the fat ones I'm a thin man."
-- Norton Juster, The Phantom Tollbooth

For years DBAs (and users) have been searching for the elusive ‘go_faster’ initialization parameter in Oracle, only to be disappointed at every turn as no such setting exists, at least not with that name. Oracle has, (more...)

PGConf.EU, Postgres Rocks!!

On a rainy Tuesday morning we set off on a Polish Airlines flight to Warsaw.
Our target: PGConf.EU with some of the biggest crew EnterpriseDB ever sent off.
Our goal: spread the love of EDB within the PostgreSQL community, where EDB is such an intrinsic part of.

The evening before the conference promises to be an interesting one. We have rented off the Hard rock Cafe in Downtown Warsaw for the kickoff of our (more...)

It’s From The Catalog


"Have you ever heard a blindfolded octopus unwrap a cellophane-covered bathtub?"
-- Norton Juster, The Phantom Tollbooth

Database upgrades aren’t terribly difficult in general, unless the upgrade is for an RMAN catalog database that has two catalogs with different versions. It’s completely ‘legal’ to have an 11.2.0.x RMAN catalog database with an additional 12.1.0.x catalog; this is where the going can get rough during an upgrade since the (more...)

Exadata Flash Cache enabled for Write Back

During Tests for an Migration of a major customer application we saw in our AWR reports that most of the jobs are very write intensive. This was the point where we would like to test what happens when we change the Flash Cache Mode from Write Through to Write Back.

What are the main benefits of Write Back mode:

  • it improves the write intensive operations while writing to flash cache is faster than writing to (more...)

Jeremy on the Role on Emerging Technology

Here’s a video from our Group Vice President, Jeremy Ashely (@jrwashley)  about Emerging Technology and how it should be helping people to use the system. This is a nice, concise description of what we do and why.

Roll With It


"I know one thing for certain; it is much harder to tell whether you are lost than whether you were lost,
for, on many occasions, where you are going is exactly where you are. On the other hand, if you often find
that where you've been is not at all where you should have gone, and, since it's much more difficult to
find your way back from someplace you've never left, I suggest you go  (more...)

IoT Cloud Brewed Beer @ OOW: The Details

Now that Oracle Open World has come and gone, I have some time to go into the details of how this project was conceived and realized, and how it faired at OOW.  Let’s start with that last one.

I guess to no one’s surprise, the actual booth with (free!) beer was a crowdpleaser;  we blew through the stock of 12 kegs with time to spare.

ODC Appreciation Day : Apiary Editor

This post is my contribution to the Oracle Developer Community (ODC) Appreciation Day. The idea of the event is best explained by Oracle Base – go here.

The Apiary Editor has to count as a pretty new entry into the possible features that could be considered with Apiary only coming into the Oracle family in the last year. Apiary as a solution provides a platform by which modern REST based APIs can be designed, documented (more...)

Important Change for Grid 12.2 Upgrade and MGMTDB

I just did an Grid Infrastructure Update to Oracle 12.2 with the latest PSU Aug 2017.

I did my preparation with the help of the Doc ID 2111010.1

„12.2 Grid Infrastructure and Database Upgrade steps for Exadata Database Machine running 11.2.0.3 and later on Oracle Linux“

In the Post-upgrade Steps was written that the Management DB should be deconfigured

The deconfigure is obsolete and the (more...)

Exadata 18 available

Yes, that great news for all Exadata guys.

The documentation is also updated. So please check first the Maintenance Guide.

IoT Workshop and Robots

AppsLab has been offering the IoT Workshop since Oracle OpenWorld 2016. And over past one year we have hosted the workshop in 20 cities around world as part of Oracle Code events, plus at Kscope 2017 conference. And if you still managed to miss all the events,  Oracle OpenWorld 2017 might be your last chance 🙂

Choropleths

In this post I will simultaneously have Fun With Data and Fun With Maps. I will use public APIs to turn my Isle of Alameda into a “choropleth“, a map which displays areas that are colored or patterned in relation to data.

To do this I will need to find boundaries within Alameda that I can associate with data of some kind. For this I turn to the ultimate source of geographical data (more...)

IoT Cloud Brewed Beer @ OOW

For the past few months we have worked together with the Oracle Developer Community and Alpha Acid Brewing on a secret IoT project.   Come see (and taste!) it at the Developer Lounge in Moscone West during Oracle Open World.

Hope to see you there!

Cheers,

Open Source? We have been here before… right!

Since over half a year I have made an adjustment in my course… nothing too dramatic, but still it has had some impact.

I have chosen the path of the more pure technique again. Not in a sense that I don’t manage anymore, though I don’t, but that’s more of a side effect

That’s the Oracle Code 2017 tour, presenting current and upcoming technologies in packed sessions, providing Oracle cloud services lab for hands-on experience, and a relaxing and fun Code Lounge to be inspired! It is a large (more...)

Flashback in a Data Guard Environment but what are the steps

The Setup of an Data Guard environment with Physical Standby via Data Guard Broker was done including an Switchover. Everything fine and works as expected. (Oracle Release is 12.1.0.2 and PSU Jan 2017).

The Dev Team asked for a Flashback Database if possible a few days ago. Okay no problem. But what do I have to do exactly.

What are the steps to do? ( The requested timestamp for Flashback on (more...)

The Isle of Alameda

The best way to learn how to make your own maps is to map someplace familiar. The place I live, Alameda, is an island in the San Francisco Bay, but existing maps don’t do it justice.

So as part of my Fun With Maps project I set out to disentangle Alameda from the urban sprawl that surrounds it and, using open source data, make a cleaner map that captures the windblown isolation of a real (more...)

Problems with Adaptive Features in 12.1.0.2 What’s to do?

The Adaptive Features is divided in two parts

  • Adaptive Plans
    • the possibility to change plans during execution
  • Adaptive Statistics
    • the statistics allow plans to be built from the results of previous executions

Version 12.1 

In 12.1 both components  will be managed by the parameter „optimizer_features_enable“ and is per default on „TRUE“.

Version 12.2

In 12.2 the parameter „optimizer_features_enable“ obsolete. The adaptive feature is now controlled by two parameters

  • optimizer_adaptive_statistics default „FALSE“
  • (more...)
