Tunnelblick ovpn client for Mac os High Sierra

Tunnelblick ovpn client for Mac os High Sierra

This weekend I was playing around with Openvpn to a new site. I use Tunnelblick for this, but this time was the first time after I had upgraded my Mac to High Sierra (10.13.5). Suddenly my vpn connections didn’t want to load anymore. Tunnelblick threw these errors to me:

I was running a beta, so first thing was to install the stable release, but the message remained. This link: https://tunnelblick.net/cKextLoadError.html helped me. In high sierra to use or add modules…

Building bridges: “Bridge must not have discovery mode for LACP interface; Interface file: bondeth0;”

Building bridges: “Bridge must not have discovery mode for LACP interface; Interface file: bondeth0;”

Some days start as an exatastic day and end up grasping your hair. This post is about such a day. A brand new shiny X7 Quarter Rack exadata was being installed for a customer. This setup was a fairly straightforward one. Quarter rack, full ovm and 2 virtual clusters. Not too fancy. LACP is being used for the public network on the fibers and vlan tagging is done on the switch. Given that, my customer created a OEDA configuration using…

A heads up for my bad memory

A heads up for my bad memory

Gotcha! This post is not about memory settings at all, but a quick heads up. If you are dealing with several generations of exadata’s and you like ironhugging them as much as I do, sometimes things can get confusing. The X7 exadata has changed a bit so when you use them, it’s nice to do things right. Only way to do it right is check it, double check it and verify. One of the things which is always in my…

OCI-C orchestration error with load balancers

OCI-C orchestration error with load balancers

There are some of those days that you just don’t get it anymore. Last few days were like that for me. One of my current projects is to provide a fully redundant infrastructure in the Oracle Cloud for some critical applications. So I created the Database as a service with dataguard to another region, provisioned a vm (IAAS) for the webserver and tomcat and made some firewall rules. Check also my colleague Freek (you can find him here @dhoogfr ) his journey…

OEDA has properties too

OEDA has properties too

Some customers ask for help to fill in the Exadata Deployment assistant (OEDA for short). This is the case in my current project. They bought a shiny brand new X7 and requested assistance for the OEDA as they faced an issue with the admin network. It reproduces very easily so I will show this using a demo example. A small introduction is maybe needed for this. Most of us know the 10.x.x.x/8 or the 172.16.x.x and 192.168.1.x/24 ranges that are…

My first REST adventures

My first REST adventures

REST and ORDS are available already a long time in the Oracle database.  Now I have the opportunity to dig deeper into it. In my current project, which involves a on-premises 12.1 multitenant database to 18c in the cloud. Including the Apex upgrade from 4.2 to the default apex 5 which comes with the 18c installation. When the POC period is over, I might blog more over this project, but this is the POC phase in which we’ll see what…

Exploring 18c exadata functions

Exploring 18c exadata functions

Recently I was granted access to the finest and latest exadata. Unfortunately it’s not mine, but I was asked if I managed to log in remotely as a test. Of course I wanted to test that. As it turned out, it was the very latest build of 18c which is available for exadata. You can find the release schedules for Oracle versions here:  the single-source-of-truth MOS Note: 742060.1 – Release Schedule of Current Database Releases. I realised this was a cool opportunity…

LAB-time: upgrading Grid Infrastructure (GI) from 12.1 to 18c

LAB-time: upgrading Grid Infrastructure (GI) from 12.1 to 18c

First of all I like to start with telling you that this blog-post is intended only for testing, playing, learning,… things. It is not intended for production use and currently 18c is only available for Cloud and engineered systems environments. For on-premises availability check Mike Dietrich’s ( @MikeDietrichDE ) blog here: https://mikedietrichde.com/2018/03/20/when-will-oracle-database-18c-be-available-on-prem/ . There I like his sentence that I will quote: Anyway, for all the details and announcements, please see always the single-source-of-truth MOS Note: 742060.1 – Release Schedule of Current…

OEDA does more than you would expect: januari 2018 update

OEDA does more than you would expect: januari 2018 update

Today I was at one of my Exadata customers for a (PL/)SQL performance tuning assignment. In the meantime there is a parallel project running for a new Exadata. So as you might know, the configuration for an Exadata starts with running the OEDA-tool. The latest version can always be found on My Oracle Support note 888828.1. At the moment of writing this blog, the latest one was January 2018 with patch number 27370068. One of the things which caught our attention,…

The cloud is more than a portal: accessing the trial/promotional account

The cloud is more than a portal: accessing the trial/promotional account

TL;DR I will save you 5 minutes when you want to access the Oracle database as a service via REST on your promotion account when it’s (automatically) coupled to your Identity cloud service (IDCS). Like many people I have a personal promotion account on the Oracle cloud to play with the Oracle Database as a service. Some of you know that I like to do things in commandline more than clicking around in a portal. The REST api is pretty…
