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,…

Compute node disk expansion resulted in mount.ocfs2: Bad magic number in superblock while opening device /dev/sda3

Compute node disk expansion resulted in mount.ocfs2: Bad magic number in superblock while opening device /dev/sda3

Before Christmas 2017 I had the honour to expand the compute node storage for a virtualised exadata. Better said, OVM on exadata. This can be done for several reasons. The most logic one, also the reason why this customer bought the disk expansion, is that you want to create more virtual machines and you have ran out of space on /EXAVMIMAGES. The preparation is actually pretty simple. It is documented completely in the Exadata Database Machine Maintenance Guide. And look,…

This is the end my friend: EOL dates for systems

This is the end my friend: EOL dates for systems

Remember your brand new X2-2 exadata or even a V2, they were (or should have been) blazingly fast when purchased. But all things come to an end, so also the end of life (EOL) for systems strikes your systems sooner or later. From time to time I get the question “how long is my exadata system fully supported”. As always the answer is 42 or “it depends”. But in the case from engineered systems, you can be a little more…

DbaaS, but on metal: Rac on Oracle Cloud Infrastructure

DbaaS, but on metal: Rac on Oracle Cloud Infrastructure

Let’s skip some networking stuff first and do some fun tests on this Cloud infrastructure. One of the things which caught my attention is the RAC database as a service. I will split this in two separate blog posts. This one will tell you about how to create a RAC database as a service and the next one will tell you about how it performs. Let’s get started! General First step is of course log into your portal and make…

Tasting a different flavour; postgres done by an oracle dba

Tasting a different flavour; postgres done by an oracle dba

There are moments in life you put everything on a row and you want to taste a slight different flavour. Well, I had a week off and I had a play with the plain vanilla postgres. Basically I should try the EDB as it is a bit more “oracle-like”, but I had a spare solaris zone and didn’t feel like running linux, so … plain vanilla it is. First steps? Easy as … I would say anything. In my homelab…

OEDA does more than you would expect

OEDA does more than you would expect

The title summaries this complete blogpost, the OEDA (oracle exadata deployment assistant) does a lot more than you would expect. Therefor it is pretty important that you should use a recent version every time when fiddling around with virtual machines on the exadata. A simple example I just discovered and did not know about. In my previous blogpost about the bond_eth issue (find it here: http://vanpupi.stepi.net/index.php/2017/06/09/exadata-ovm-creation-second-argument-is-not-defined-bondeth_mode/ ) you could read that there was a problem while I invoked domU maker manually…

Exadata ovm creation: Second argument is not defined: bondeth_mode

Exadata ovm creation: Second argument is not defined: bondeth_mode

There are some days which start as exatastic days and end up at Oracle Support. This blogpost is (hopefully) one with temporal validity. I know that’s a 12c feature as well, but that’s another story. The error which I’ll discuss here, will tell you about the “Second argument is not defined: bondeth_mode” error in the domu maker logfile. A while ago, one of my customers asked me to extend one of their exadata’s with 2 extra compute nodes, make sure…

Exadata installation

Exadata installation

It was an exatastic day. One of our customers bought 2 exadata’s and zfssa’s. One for each datacenter. Sometimes a customer asks, how does it go. Together with a suggestion of Frits Hoogland (you can find him here: @fritshoogland) about creating an unboxing video, I came up with documenting the first steps in a simple blog. Just because … the systems were unboxed, so creating a video was a bit too challenging then. If there is an occasion, I will still create…
