Enterprise Manager 13c – Resolve Pending Status of Systems Infrastructure Server Components

From time to time you can observe, that some Systems Infrastructure Server Components are turning into a "Pending Status". Mostly the reason for this status change is not clear, a restart of the underlying Oracle Agents also doesn't resolve this pending state.


 The simplest solution to get rid of the pending state is to remove the Systems Infrastructure Server Component and to re-add it.

For this just connect with the oracle user to your server (more...)

Microsoft Azure: How to use waagent (Microsoft Azure Linux Agent)

After installation waagent on my ubunu server, i tried to use this tool.
First guess was to read the manpages, but there is no entry for waagent:
root@ubuntuserver:~# man waagent
No manual entry for waagent
See 'man 7 undocumented' for help when manual pages are not available.
So for documentation you have to visit the Microsoft Azure portal:
https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/agent-linux



Here are some commands i tried:
root@ubuntuserver:~# waagent -show-configuration
AutoUpdate.Enabled = True

General

Lies, darn lies and sampling bias

Sampling profiling is very powerful technique widely used across various platforms for identifying hot code (execution bottlenecks).

In Java world sampling profiling (thread stack sampling to be precise) is supported by every serious profiler.

While being powerful and very handy in practice, sampling has well known weakness – sampling bias. It is real and well-known problem, though its practical impact is often being over exaggerated.

A picture is worth a thousand of words, so let (more...)

Microsoft Azure: Administration of Virtual Networks / Diagrams

After creating my first vm on Microsoft Azure, i took a closer look at the dashboard - especially at the menu bar of the dashboard:
First point of interest was the menu item "virtual networks", which led me to the following overview:
Hm. A little bit strange, that the virtual networks just show up with a list of the resource groups (you have to create one - otherwise you are not able to launch a (more...)

Last Week in Stream Data Integration & Stream Analytics – 4.3.2019

This is the 147th edition of my blog series blog series around Stream Data Integration and Stream Analytics! I have slightly changed the title to better reflect the content of by weekly blog series.

In-App Guides #1 – Oracle Guided Learning

Last month I started looking at in-app guides and Fusion – with the aim of finding the best service to increase user adoption and decrease the need for training.

The first that I’ve managed to see working is Oracle Guided Learning. It’s a product that they’ve acquired (Iridize was one of the market leaders pre September 2018’s acquisition) and I’ve been lucky enough to speak to one of the key people from Iridize who (more...)

Microsoft Azure / Ubuntu: Installation waagent

If you want to build your own Linux images for Microsoft Azure, you have to use waagent. So i created a virtual machine on my local host with ubuntu server.
The installation of waagent is easy, if you know, that the package is not called waagent on ubunut but walinuxagent:
# apt install walinuxagent
Reading package lists... Done
Building dependency tree      
Reading state information... Done
The following NEW packages will be installed:

I’m Changing My Profile – I’m NOT Not technical


I'm changing my profile.

'I'm not technical but.............' that's how many of my presentations start.

Occasionally someone would say I was, and I'd just laugh it off.


I'm changing my profile. Let me tell you Why:

A few weeks ago someone I really admire, asked me to if I wanted to be considered for a Women in IT celebration panel. I was really honoured to be asked.

However the response I got when (more...)

Microsoft Azure: Where to find the logs

When working with Microsoft Azure, you want to be able to review all actions taken inside your cloud. Therefore you have to go to "monitor":
Inside the subwindow just select "activity log" and edit the filters to your needs (i added "successful):

Some of the activities can be further drilled down. For example the creation of a virtual machine lists many subactivities like "created or updated public ip address":





Fishbowl Solutions helps a key Customer gain efficiencies and cuts costs through the implementation and data migration of PTC Windchill PartsLink & Supplier Management

The Situation

A global commerce and technology company needed a better way to keep track of standard parts and supplier information for their electrical components and boards. Their solution was to develop a homegrown database application that grew over time into a more complex app. It worked. Though the app addressed their needs, over the years it became more difficult and expensive to maintain. Eventually, this homegrown solution could only run on outdated, unsupported infrastructure… (more...)

Hands-on with Chatbots (part 1)

I spent two days last week with a couple of colleagues in Oracle’s city office looking at Chatbots – or ODA (Oracle Digital Assistants) to give them their correct name. It was a really useful workshop.

chatbots

I had been under the misapprehension that chatbots were earlier on the hype cycle than they actually are. Yes, a chat interface will replace most self-service UIs, but that’s 3-5 years off, right? Maybe not.

Continuous Integration & Deployment with OIC

Whilst OIC is not a traditional development environment, once you get past simple integration development you’re going to want to start implementing some configuration management controls and release promotion mechanisms.  We discussed this in the book, and illustrated how this can be achieved in a simple manner using the OIC APIs. However this can be […]
