2018 Sangam – Encouraging the Local Presenters


At the Oracle ACE session at #Sangam18, all ACE speakers were asked what they thought the program meant to them. I talked about the part of our role that is to encourage local speakers. I shared the story that when I first went to South America on an ACE tour the events were small with few local speakers, that is now defiantly not true and they have many ACEs including Directors, they just needed (more...)

AWS: Accessing S3 buckets from the internet and from ec2 instances

After reading about endpoints for AWS S3 i was wondering how i can use this feature.

First step was to create a bucket and just tried to access this bucket over the internet:

$ aws s3api create-bucket --bucket my.webtest --region eu-west-1 --create-bucket-configuration LocationConstraint=eu-west-1
{
    "Location": "http://my.webtest.s3.amazonaws.com/"

2018 Sangam – A Tale of Two Journeys


A few weeks ago, when posting I was going to Sangam I talked about my Yathra trip which whilst I loved the conferences, I hated the travel!

I have always been a nervous passenger on roads. In fact I am a real pathetic person, who used to hide behind the sofa when Dr Who was on, and have never come out from there. I can’t watch horror or sci-fi films and even dramas I close (more...)

AWS: IAM & security – Best practices: Using a non-root user

After my successful solutions architect practice i knew that i had to take care of my shortcomings in security.
So i decided to visit the IAM (Identity and Access Managemen) of AWS:

  • Delete your root access keys
    I created them for using aws cli (installation or creating a static webpage)
  • Activate MFA on your root account
    No - i will not use multi factor authentication for my playground.
  • Create individual IAM users

Ubuntu: if WLAN is gone after an update and lspci lists no wlan devices

On my ubuntu laptop after an update the WLAN networking was gone. First check was to boot into Windows and check wether the WLAN devices is still working:
The WLAN still worked with Windows, so the worst case (hardware error) did not hit me ;-)

ODA – Update to 12.2.1.4 – issue with ora.net1.network

Yesterday, I had to update an ODA from Release 12.1.2.12 to 12.2.1.4 . All prerequisite checks including prepatchreport were successful ... but the update itself not!

During the update, at stage 'GI Home Cloning', the update process failed and left the system in an 'unknown' state. A detailled analysis has shown the root cause: crs service qosmserver is missing. So, I tried to setup this missing link to a successful update:

Leveraging Google Cloud Search to Provide a 360 Degree View to Product Information Existing in PTC® Windchill® and other Data Systems

Most organizations have silos of content spread out amongst databases, file shares, and one or more document management systems. Without a unified search system to tap into this information, knowledge often remains hidden and the assets employees create cannot be used to support design, manufacturing, or research objectives.

An enterprise search system that can connect these disparate content stores and provide a single search experience for users can help organizations increase operational efficiencies, enhance knowledge (more...)

AWS: What services are free of charge? How to control your costs…(part 3)

After looking into my bill (see post 1 and post 2) i was keen, how fine granular the cost statistics are inside the aws web console. So i moved to the billing dashboard and to the cost explorer:
This provides you with the following dashboard:
You can play around with the settings to get for example something like this:




AWS Billing: Set an alarm to a cost threshold

Knowing about some details about the costs inside aws and some of the services (especially, that Docker, VPNs and Kubernetes are not included in the free trials)

The Cedar/V1 Knowledge Day

Every year at Cedar we hold a ‘Knowledge Day’, where all our employees come off-site and gather in a hotel somewhere to share knowledge. Although there’s significant lost revenue, it’s an invaluable way of getting everyone together and keeping our skills current. It was particularly pleasing that after being acquired our new owners were supportive of the event – with some Version 1 execs having speaking slots.

We spent the morning as a complete group (more...)
