In recent years, few aspects of modern life have enterprises and techies drooling more than the cloud. The amount of cloud of data centers dominated by tech giants, Amazon, Microsoft, Google and Oracle is stagering and it is not stopping any time soon. During the Covid-19 pandemic, they have helped transform people’s lives, supporting a change in the way we work (from home), and even how we consume ...
This will be a small post and is mostly for me to remember how to do it. The other day I was asked to provide all of the resources that we had in OCI , and I did try to do it via the GUI interface, but I thought that what I could do with OCI CLI was much better and simpler.
This first thing that you have to ...
As you may already know, scripting your RMAN backups and storing your connectivity credentials in the actual scripts is not a good security practice. Sometimes even hiding the actual password through another script or a mechanism for this will expose your password. I won’t go into details as of why you should not do this, but you can see Simon’s post about it.
The best way ...
A couple of weeks ago, I was helping out a teamate with a post patch issue on the ExaCC, The problem was that after applying the 19.12 RU to the DB ORACLE_HOME, the PDBs were left in restricted mode and couldn’t be opened. So my first train of thought is to check the PDB_PLUG_IN_VIOLATIONS to see what was going on

It has been 4 years and almost 3 months that on September 19th (19s as it is commonly known due to the day 19th and S of September) of 2017 at 1:15 PM CT México City got hit by one of the deathliest earthquake. México City is still in the process of removing and fixing buildings that were damaged by that earthquake.
On an analogy of an earthquake, the ...
Lately I have been testing the GC project “El Carro” and it came to light that I hadn’t done a 101 of Kubernetes or also known as K8s and following Christine’s post on learning something new, I think this can help out newcomers. I will be doing a couple of posts on this topic, so I hope you follow the series
I am going to try to ...
This will be a small post on how to do an Out of Place Patching for your database in an ExaCC environment. The documentations shows how to do it via the console, but in this example it will be a 19.11 patch via dbaascli that will be applied to the database. One thing to know is that unless stated other wise, all commands are run with root
The first ...
This week we had an issue when we were patching and EXACC Grid Infrastructure from 19.10 to 19.11 and the patching died when it was running the postpatch on node 1 and left the patch in a weird “ROLLING PATCH” mode as it hadn’t finished the 19.11 patching (rootcrs.sh -postpatch) in node 1 and node 2 was still running 19.10.
What you see below is the command that was ...
This blog post is part rant and part on how I was able to fix an issue in the second instance that was failing with ORA-01102: cannot mount database in EXCLUSIVE mode when trying to start it up.
Yesterday a teamate mentioned to me that when he was trying to bring up the second instance, in a 2 node 19.10 RAC environment, he was not able to and it was ...
Seems that lately I have been getting all of the ORA-00600 errors possible when duplicating databases, and this is just another one in the list. This will be a very short blog post on how I worked around ORA-00600 when duplicating a PDB and TDE is enabled in the Source PDB in a 19.10 version.
Over the last months, the team had been seeing this ORA-00600 intermittently when ...
This week I was involved in an issue with a QA pluggable database refresh that is critical to business, where after the PDB clone to the QA container caused an ORA-00600 error and then the container crashed and it was not possible to start it, failing with the same error.
I will explore in this blog post how I brought the container up, though it goes to say ...
I will start this post that the script I am talking about might already be somewhere out there and even in a better version, but myself I couldn’t find it and I needed something that I could quickly put in cron.
The script I wrote is called oci_ocpu_scale.sh and I can put it in cron and scale up or down the OCPUs at a certain time of the ...
This will be a small blog post to help you patch your EM 13c environment to the latest release unit, which is 13.4.0.10. Which I highly recommend, as it fixes a bug (32288282) if you are planning to upgrade from EM 13.4 to 13.5.
The first thing is to download the following three patches:
For some, this past year has been full of doubts, fears, loneliness, and even loss. I count myself as part of these “some”. But like anything in life, it has also been filled with life, happiness, and some of the greatest experiences I have had in my 42-year life.
One of these changes has been accepting a new job at Eclipsys and I can say it is one decision ...
Staying with the GCP 101 series, I will now explain how you setup an NFS mount from a GCP filestore for RMAN backups.
I want to keep on mentioning that first you should check with Oracle and your licensing rep on what is supported and licensed before doing any of this work.
I have previously built 2 VMs that I am using for these exercises and the steps are in ...
