You might be thinking:

Oracle Database 18c

Yup…it’s arrived!

New name obviously, because we’ve jumped to our new naming model to align with the calendar year as opposed to version number.  You might be thinking “So what?” but it’s a significant change in the way we getting software to customer.  Mike Dietrich blogged about this at length here so I won’t repeat what has been said, but in TL;DR form:

More frequent releases, with smaller amounts of change per release

In this way, the approach lets us focus more of solidifying existing features, and being able to quickly respond to bugs that arise.

So 18c is more an incremental release on 12.2 (in fact, internally it was referred to as “12.2.0.2” for most of it’s build cycle) focussed on stability and hardening of existing features.

Solaris Cluster and Decreasing Resource Needs After Upgrade

Delphix Engineering and Support are pretty amazing folks.  They continue to pursue for solutions, no matter how much time it takes and the complex challenges they’re faced with supporting heterogenous environments, hardware configurations and customer needs.

This post is in support of the effort from our team that resulted in stability to a previously impacted Solaris 11.2 cluster configuration.  The research, patching, testing and then resulting certification from Oracle was a massive undertaking from our team and I hope this information serves the community, but in no way is recommended by Delphix.  It’s just what was done to resolve the problem, after logical decisions for the use of the system by our team.

Upgrading an Amazon EC2 Delphix Source, Part III

This is the Part III in a four part series on how to:

  1.  Enable VNC Viewer access on Amazon EC2 hosts.
  2.  Install DB12c and upgrade a Dsource for Delphix from 11g to 12c, (12.1)
  3.  Update the Delphix Configuration to point to the newly upgraded 12c database and the new Oracle 12c home.
  4.  Install DB12c and upgrade target VDBs for Delphix residing on AWS to 12.1 from the newly upgraded source.

In Part II, we finished upgrading the Dsource database, but now we need to get it configured on the Delphix side.

Samsung Phones with 6.01 Update and Failures on Email Sends, Social Media, etc.

I was surprised on April 20th when I awoke to find a 1.3G OS update on my Samsung Galaxy 6 Edge+.  I’d never experienced any issues with an update before, so I quickly connected my phone to the WiFi and let it download then upgrade my phone, anxiously awaiting what new Android features awaited me.

Enterprise Manager Cloud Control 13c Upgrade

em-12cA couple of weeks ago I posted about doing a fresh installation of Enterprise Manager Cloud Control 13c (article, blog post). I’ve finally got around to doing an upgrade test from EM CC 12cR5 to 13cR1. You can see the result of that here.

Upgrade a Pluggable Database in #Oracle 12c

This is how an upgrade with pluggable databases looks conceptually:
You have two multitenant databases from different versions in place. Preferably they share the same storage, which allows to do the upgrade without having to move any datafiles
Initial state

You unplug the pluggable database from the first multitenant database, then you drop it. That is a fast logical operation that does not delete any files

unplug drop

Next step is to plug in the pluggable database into the multitenant database from the higher version

Cloud Control 12.1.0.5 : It’s production upgrade day…

cloudI mentioned a couple of months ago I was planning to upgrade our production Enterprise Manager Cloud Control installation from 12.1.0.4 to 12.1.0.5. Well, today was the day. I held back a while because I knew I would be out of the country for a while on the Latin America tour and I didn’t want to make a big change before I ran away. :)

Upgrade Cloud Control 12cR4 to 12cR5

em-12cA couple of weeks ago I wrote a post about doing a Cloud Control 12cR5 installation and said I would be testing the upgrade from 12cR4. I’ve now done that.

Enterprise Manager Cloud Control 12cR4 Production Upgrade

I’ve already written about the 12cR3 to 12cR4 upgrade here. I did a few run through’s at home to practice it and it all seemed good.

Setting The Scene

Just to set the scene, for our production environment we run Cloud Control in a VMware virtual machine, using Oracle Linux 6.5 as the quest OS. With that setup, we can use a simple installation (DB and OMS on the same VM) and use VMware to provide our failover, rather than having to worry about multiple OMS installations and any DB failover technology etc. If there’s one thing I’ve learned about Cloud Control, it’s Keep It Simple Stupid (KISS)! As far as our managed servers go, most of our databases and all our middle tier stuff runs on VMware and Oracle Linux too. We have a handful of things still hanging around on HP-UX and Solaris, which will hopefully be migrated soon…
