Within the Oracle iPaaS products you will encounter features that exist to help provide security or mitigate the risks of someone misusing Oracle cloud accidentally (or otherwise). These features look to mitigate security issues such as a Denial of Service (DoS) attack (e.g. flooding a web service with more calls than it can handle preventing […]
I prefer to write blog posts about the interesting questions on OTN. This blog post is one of them. There are usually more than one EM admins managing the systems, and you may want to track other users’ activity. Enterprise Manager Cloud Control provides auditing mechanism called “comprehensive auditing”. It’s not enabled by default for all actions because it may consume a lot of disk space.
If you want to enable it for all actions, (more...)
It has been about three months since I’ve published a post. Well this time it has been a mix of work and decision making on my next chapter in my career that has kept me from posting. Hopefully, in the near future I will have more time to publish articles on topics I really want to discuss.
For the people close to me, many of you already know what this change is. I appreciate that (more...)
This blog post is about two things: one how you can monitor who is bringing you database up and down (there is a twist at the end!) and two how you can very conveniently do that with aggregated logs in a browser with a tool called ‘Kibana’, which is the K in ELK.
What is the ‘ELK stack’?
The ELK stack gets it’s name from Elasticsearch, Logstash and Kibana.
– Elasticsearch is an open (more...)
It’s been a busy month – five Exadata deployments in the past three weeks and new personal best – 2x Exadata X6-2 Eighth Racks with CoD and storage upgrade deployed in only 6hrs!
An issue I encountered with the first deployment was that onecommand wouldn’t change the storage cells names. The default cell names (not hostnames!) are based on where they are mounted within the rack and they are assigned by the elastic configuration (more...)
On Oracle Community forum, I’ve seen a good question about using EMCLI to add targets. The forum user says that they decided to name the database targets with combining db_name and hostname. As you may know, when you add a database target, EM also creates a database system for the new target (or assign it with an existing one). The new database system’s name is generated by adding “_sys” to the database target name. Let’s (more...)
So Brent Ozar’s group of geeks did something that I highly support- a survey of data professional’s salaries. Anyone who knows me, knows I live by data and I’m all about transparency. The data from the survey is available for download from the site and they’re promoting app developers to download the Excel spreadsheet of the raw data and work with it.
Now I’m a bit busy (more...)
Here’s a quick post to help with LUN, SAN or File migration when using Oracle ASM.
Please note that this is just an example method, and it not a definitive guide.
You need to ensure your approach is appropriate for your environment.
Did you know that you can add and drop disks on a diskgroup in a single command.
This saves Oracle from doing 2 REBAL actions and speeds things up considerably using a lot (more...)

Please submit for the Exaday 2017 all around the topic Oracle Engineered Systems
I receive about 20-30 messages a week from women in the industry. I take my role in the Oracle community as a role model for women in technology quite seriously and I’ve somehow ended up speaking up a number of times, upon request from different groups.
It’s been discovered that after applying 188.8.131.52.161118 Windows DB Bundle Patch 24922870, both DBCA and DBUA no longer function and give the following error:
Oracle Support have only filed a bug on Wednesday this week (11th January 2017):
Bug 25369562 : DBCA & DBUA NO LONGER FUNCTION AFTER APPLYING PATCH 24922870
So if you’re planning to use either DBCA or DBUA after applying the patch, you might want to hold off till (more...)
I was investigating gathering performance data on (oracle) linux servers recently and came across Performance Co-Pilot (PCP). I have come across this product regularly in the past, but it seemed somewhat abstract to me, and I never ran into any actual usage. And we got sar for linux performance data and for the Oracle database we got oswatcher (and it’s exadata cousin exawatcher) and TFA right? How wrong I was.
First let me explain a (more...)
I had the pleasure to deploy another Exadata in the first week of 2017 and got my first issue this year.
As we know starting with Exadata X5, Oracle introduced the concept of Elastic Configuration. Apart from allowing you to mix and match the number of compute nodes and storage cells they have also changed how the IP addresses are assigned on the admin (eth0) interface. Prior X5, Exadata had default IP addresses set at (more...)
SQLT is a tool that collects comprehensive information on all aspects of a SQL performance problem. SQL tuning experts know that EXPLAIN PLAN is only the proverbial tip of the iceberg but the fact is not well recognized by the Oracle database community, so much evangelization is necessary.
I remember the time I was trying to solve a production problem a long time ago. I did not have any tools but I was good at (more...)
Over the many years Oracle has been leading the database world, I guess they are now taking something of a wrong turn.
Let me briefly fill you in on my thoughts.
Basically I see two “minor” shifts that are significantly indicative of this:
- Oracle Standard Edition 2
- Oracle ACE Program
Okay, so you might think I am crazy, but let me try to explain.
Oracle Standard Edition 2
Sometime last year, the long expected, (more...)
It’s always a challenge when you want to build your own Oracle SQL Tools. I was asked how you could synchronize multiple cursors into a single source. The answer is quite simple, you write an Oracle object type to represent a record structure, an Oracle list of the record structure, and a stored function to return the list of the record structure.
For this example, you create the following
table_struct object type and a
How was 2016 for me?
It was a surprisingly busy year- blogging, speaking, working and doing.
I posted just under 100 posts to my blog this year. After I changed jobs, the “3 per week” quickly declined to “4 per month” after I was inundated with new challenges and the Delphix learning curve. That will change for 2017, along with some new initiatives that are in the works, (more...)
When I carried out my first Exadata patching, I came across ‘Linux Screen‘ in the documentation, which Oracle recommended to use when patching:
“It’s recommended to run the dbnodeupdate.sh session using the Linux ‘screen’ or ‘vnc’ utility such that when a network problem breaks the connection to the server the patching session continues.”
Basically ‘Linux Screen‘ allows you to:
- Have a shell that can be reconnected to if you (more...)

It's the start of a new year , and as with all new years it's time to prepare and start learning a fresh. Oracle as a database , as a technology , as a field is constantly being update from being a database to a platform to a cloud provider .
Learning is the core of what we thrive to do . as technology evolves , the opportunities to learn increase .
