Exadata patch pre-check fails due to wrong server model

I've been mostly busy with OCI-C and OCI in the past three years but occasionally I have to patch Exadata systems. That's what I have been doing every quarter for a Norwegian customer, patch their prod and non-prod Exadata systems in two consecutive weekends. The Exadata configuration was an X5-2

Installing Oracle BIP 12.2.1.4

As part of my middleware journey I had to install BI Publisher (BIP) on Supercluster (Solaris) and was surprised by the error below: [2020-08-19T16:19:51.077+01:00] [as] [NOTIFICATION] [] [oracle.as.install.engine.modules.validation.oracle.as.install.engine.modules.validation.handler.homeQueries.verifyAllDependencies] [host: soahost1] [nwaddr: 192.

Scaling Exadata Cloud Service X8M Compute

Following my last week post on how to provision Exadata Cloud X8M service, I'm going further this week with scaling the infrastructure with more compute nodes. Until now scaling an existing X6, X7 or X8 systems in OCI would require moving the system to a different fixed shape configuration. For

Long time no updates from me. Hope you are all well. I'm currently working on a Supercluster project where I provide database support. To help my colleagues and the whole project I decided to step out of my comfort zone and install the latest 12.2.1.4 version of

Well it's been almost three years since my last post and while I haven't blogged for that long I am still working with Oracle technologies. I joined Accenture Enkitec Group in February 2018 and I've been working on a big migration project to Oracle Cloud Infrastructure for a UK customer

Upgrading to Exadata 12.1.2.2.0 or later - mind the 32bit packages

This might not be relevant anymore, shame on me for keeping it draft for few months. However, there are still people running an older versions of Exadata storage software and it might still help someone out there. With the release of Exadata storage software 12.1.2.2.0, Oracle

Installing OEM13c management agent in silent mode

For many customers I work with SSH won't be available between the OEM and monitoring hosts. Therefore you cannot push the management agent on to the host from the OEM console. Customer might have to raise CR to allow SSH between the hosts but this might take a while and

OTN Appreciation Day: Oracle Data Guard Fast-Start Failover

Thank you, Tim, for the great idea. There are so many cool database features one could spend weeks blogging about them. A feature which I like very much is Oracle DataGuard Fast-Start Failover, FSFO for short. Oracle DataGuard Fast-Start Failover was one of the many new features introduced in Oracle

How to enable Exadata Write-Back Flash Cache

Yes, this is well-known and the process has been described in Exadata Write-Back Flash Cache - FAQ (Doc ID 1500257.1) but what the note fails to make clear is that you do NOT have to restart cell services anymore hence resync the griddisks! I had to enable the WBFC

Extending an Exadata Eighth Rack to a Quarter Rack

In the past year I've done a lot of Exadata deployments and probably half of them were eighth racks. It's one of those temporary things - let's do it now but we'll change it later. It's the same with the upgrades - I've never seen anyone doing an upgrade from
