DOAG 2018: Best of Oracle Security 2018

Alexander Kornbrust - Sun, 2018-11-25 05:49

Last week I gave my yearly presentation “Best of Oracle Security 2018” at the DOAG 2018 conference in Nürnberg. In this presentation I talked about different Oracle exploits, a vulnerability in livesql.oracle.com, DNS data exfiltration in Oracle and how to audit SYSDBA connections in Oracle

 

Additionally I talked about the German DSGVO (GDPR) – „Wie wird die DSGVO umgesetzt und welche Lücken/Lügen gibt es?

Oracle ADF + Jasper Visualize.js = Awesome

Andrejus Baranovski - Sun, 2018-11-25 02:36
This week I was working on a task to integrate Jasper Visualize.js into Oracle ADF application JSF page fragment. I must say integration was successful and Jasper report renders very well in Oracle ADF screen with the help of Visualize.js. Great thing about Visualize.js - it renders report in ADF page through client side HTML/JS, there is no iFrame. Report HTML structure is included into HTML generated by ADF, this allows to use CSS to control report size and make it responsive.

To prove integration, I was using ADF application with multiple regions - ADF Multi Task Flow Binding and Tab Order. Each region is loaded with ADF Faces tab:


One of the tabs display region with Jasper report, rendered with Visualize.js:


Check client side generated code. You should see HTML from Visualize.js inside ADF generated HTML structure:


It is straightforward to render Jasper report with Visualize.js in Oracle ADF. Add JS resource reference to Visualize.js library, define DIV where report supposed to be rendered. Add Visualize.js function to render report from certain path, etc.:


Sample code is available on my GitHub repo.

Flashback to the DOAG conference 2018

Yann Neuhaus - Sat, 2018-11-24 14:40

Each year, since the company creation in 2010, dbi services attends the DOAG conference in Nürnberg. Since 2013 we even have a booth.

The primary goal of participating to the DOAG Conference, is to get an overview about the main trends in the Oracle business. Furthermore, this conference and our booth allow us to welcome our Swiss and German customers and thank them for their trust. They’re always pleased to receive some nice Swiss Chocolate produced in Delémont (Switzerland), city of our Headquarter.

But those are not the only reasons why we attend this event. The DOAG conference is also a way to promote our expertise with our referents and to thank our performing consultants for their work all over the year. We consider the conference as a way to train people and improve their skills.

Finally some nice social evenings take place, first of all the Swiss Oracle User Group (SOUG) “Schweizer Abend”, the Tuesday Evening, secondly the “DOAG party” on Wednesday evening. dbi services being active in the Swiss Oracle User Group, we always keep a deep link to the Oracle community.

As a Chief Sales Officer I tried to get an overview of the main technical “Oracle trends”, through the successes of our sessions (9 in total) all over the conference. The “success” being measured in term of number of participants to those sessions.

At a first glance I did observe a kind of “stagnation” of the interest about Cloud topics. I can provide several evidences and explanations about that. First of all the Key Note during the first day presenting a study over German customers concerning the cloud adoption didn’t reveal any useful information, according to me. The Cloud adoption increases, however there are still some limitations in the deployment of Cloud solutions because of security issues and in particular the cloud act.

Another possible reason about the “small” interest about Cloud topics during the conference, according to me, relies on the fact that Cloud became a kind of “commodity”. Furthermore, we all have to admit that Oracle has definitively not a leadership position in this business. Amazon, Azure and Google definitively are the leaders in this business and Oracle remains a “small” challenger.

Our session from Thomas Rein did not had so much attendees, even if we really presented a concrete use case about Oracle Cloud usage and adoption. The DOAG conference is a user group conference, Techies mostly attend the conference and Techies have to deal with concrete issues, currently the Oracle Cloud does not belong to them.

So what were the “main topics” according to what I could observe ?

Open Source had a huge success for us, both the MySQL and the two PostgreSQL tracks were very very successful, thanks to Elisa Usai and Daniel Westermann.

Some general topics like an “introduction to Blockchain” also had a huge success, thanks to Alain Lacour for this successful session.

Finally the “classicals”, like DB tuning on the old-fashion “On Prem” architectures also had a huge success, thanks to our technology leader Clemens Bleile and to Jérôme Witt who explained all about the I/O internals (which are of course deeply link with performance issues).

Thanks to our other referents: Pascal Brand (Implement SAML 2.0 SSO in WLS and IDM Federation Services) and our CEO David Hueber (ODA HA: What about VMs and backup?) who presented some more “focused” topics.

I use this Blog post to also thank the Scope Alliance and in particular Esentri for the very nice party on Wednesday Evening, beside hard work, hard party is also necessary :-)

Below, Daniel Westermann with our customer “die Mobiliar” on the stage, full room :

AWS: What services are free of charge? How to control your costs...(part 2)

Dietrich Schroff - Sat, 2018-11-24 02:47
In November i did several tests with AWS:
A big question is: Was this really free of charge?
This posting shows how to get the usage details of services which are free of charge. 

Here now some details about EKS, ECS and VPC. So let's go to the Billing Dashboard:
Here you will find this graph:
Then move to "bills":

Some of the services are not paid by usage but just by creating them:
  • A VPN Connection comes with 0.05$ per Hour.
  • Kubernetes costs 0.2$ per hour
So if you want to explore AWS, you have to be fast - otherwise you have to pay for being slow ;-)

My DOAG Debut

Yann Neuhaus - Fri, 2018-11-23 08:50

Unbelievable! After more than 10 years working in the Oracle Database environment, this year was my first participation at the DOAG Conference + Exhibition.

After a relaxed travel to Nürnberg with all the power our small car could provide on the German Autobahn, we arrived at the Messezentrum.
With the combined power of our dbi services’ team, the booth was ready in no time and we could switch to the more relaxed part of the day and ended up in our hotel’s bar with other DOAG participants.

The next few days were a firework of valuable sessions, stimulating discussions and some after hour parties who gave me to think about my life decisions and led me to the question: Why did it take me so long for participating in the DOAG Conference + Exhibition?

It would make this post unreadable long and boring if I would sum up all sessions I attended.
So I will just mention a few highlights with the links to the presentations:

Boxing-Gloves-Icons

Boxing Gloves Vectors by Creativology.pk

And of course, what must be mentioned is The Battle: Oracle vs. Postgres: Jan Karremans vs. Daniel Westermann

The red boxing glow (for Oracle) represents Daniel Westermann, Oracle expert for many many years who now is the Open Infrastructure Technologie Leader @ dbi services, while Jan Karremans, Senior Sales Engineer at Enterprise DB put on the blue glow (for Postgres). The room was fully packed with over 200 people who have more sympathy for Oracle.

 Oracle vs. Postgres

The Battle: Oracle vs. Postgres

Knowing how much Daniel loves the Open Source database it was inspiring to see how eloquent he defended the Oracle system and brought Jan multiple times into troubles.
It was a good and brave fight between the opponents in which Daniel had the better arguments and gained a win after points.
For the next time, I would wish to see Daniel on the other side defending Postgres because I am sure he could fight down almost every opponent.

In the end, this DOAG was a wonderful experience and I am sure it won’t take another 10 years until I come back.

PS: I could write about the after party, but as you know, what happens at the after party stays at the after party expect the headache, this little b… stays a little bit longer.

PPS: On the last day I’ve got a nice little present from virtual7 for winning the F1 grand prix challenge. I now exactly on which dbi event we will open this bottle, stay tuned…

DOAG 2018: Key word: “Docker”

Yann Neuhaus - Fri, 2018-11-23 06:34

Capture

In my blog about the DOAG Last year I said that saw a growing interest on the automatic deployment tools and Docker containers. This year confirmed the interest. They were a lot of presentations about Docker containers, Kubernetes, OpenShift. This for the database stream, the DevOps stream but also the Middleware one. I numbered more than 25 sessions where the keyword Docker appeared in the Abstract.

Despite my will, I was not able to assist to all of those. They were to many to be able to.

One of those interesting presentations that retained my attention was the following one: “Management von Docker Containern mit Openshift & Kubernetes” from Heiko Stein. He gave us a very good overview of the services for Kubernetes and Openshift and showed us how they can be complementary.

An other one was about monitoring and diagnosing performances of a Java application (OpenJDK 11) running in a Docker Container.
Monitoring of JVM in Docker to Diagnose Performance Issues. This one was interesting at several levels, as it talked about: Docker container, OpenJDK 11 and the tools that are delivered with. Monitring applications and diagnosing issues are always interesting subjects to follow to get some hints from someone else experiences.

The last I will list but not the least one was “MS Docker: 42 Tips & Tricks for Working with Containers“. This one in summary is all you ever wanted to know about Docker. But the 45 minutes sessions were really to short to get everything from it :-(.

Those presentations just made my interest for those technologies grow faster.

My first presentation at the DOAG – “MySQL 8.0 Community: Ready for GDPR?”

Yann Neuhaus - Fri, 2018-11-23 02:35

This year I participated for the first time to the DOAG, the conference which takes place in November in Nuremberg. Here some key words about this event: Oracle and other technologies, 2000 visitors, more than 400 sessions, more than 800 abstracts sent, exhibitors…
And for me everything started when in June I decided to send an abstract for a MySQL session.

Preparation

I’ve been working on MySQL for several years. At the beginning of this year, I started testing the new 8.0 version. We live in an age where security is more important than ever, GDPR and other regulations force us to review some subjects such as privacy and data policies. MySQL put in place lots of improvements regarding security in this last version.
So my session proposal for the DOAG was the following one:

MySQL 8.0 Community – Ready for GDPR ?
One of the most topical subject today is security.
New MySQL 8.0 version introduces several improvements about that, such as:
Encryption of Undo and Redo Logs, which comes to enrich existing datafile encryption
Password rotation policy, to avoid a user to always use the same passwords
New caching_sha2_password plugin, which let you manage authentication in a faster and more secure way
SQL Roles, to simplify the user access right management
So… let’s have a look!

When I received the e-mail that told me that my abstract had been accepted, I was happy and stressed at the same time.
I directly started testing and studying more and more these new features, writing my slides and preparing some demos and my speech in English. I know, for the most of you this is simple, but – hey – this would have been my first session ever! ;)
Working at dbi services is also the possibility to present a session to colleagues and so to test it and have some feedback during our internal events, before presenting this same session to abroad/external events. So in September I could present my session a first time and this helped me to feel more comfortable about the fact of presenting something. Time passed and November was suddenly there…

Arriving to the DOAG

So on 19th November I caught my flight and at 7pm I was in Nuremberg. And the day after I arrived to the Conference Center.
badge
doag
My session was planned for 3pm so I had some time in the morning to visit some booths and people that I wanted to meet (Oracle MySQL, Quest, EDB, and my colleagues on booth of dbi services).
dbi services
And I also got some useful tips from my colleagues to calm my stress and better manage my session: take a few seconds before starting talking to catch the visual attention of the audience, breath correctly, visit the room before, and so on (thank you guys for your support during the last weeks!).

My session

The expected moment came, my VMs were running for demos and slides ready, and some people arrived in the room.
IMG_9528
I started my talk with a little introduction to GDPR explaining the importance of having some privacy and data policies in our hyper connected world. And this aspect let me doing a link with the fact that MySQL 8.0 came out with lots of improvements in terms of security.
So I finally could go deeper into technical part to explain these new important features:

- SQL Roles:
Thanks to roles, we could have a faster user administration and grant handling is managed in a centralized way. During the session I did a demo to explain how roles are created and activated in MySQL and I used the yEd desktop application to generate the diagram of the whole roles representation from a graphml file.
For more details about roles, read my previous blog and the MySQL Documentation.

- Password Reuse Policy:
It avoids users to use previous passwords. This can be activated in order of changes (with the system variable password_history) or time elapsed (password_reuse_interval) and it’s not valid for privileged accounts.

- Password Verification Policy:
If this feature is activated, attempts to change an account password require before to specify the current password to be replaced.
For more details about password verification policy, read my previous blog and the MySQL Documentation.

- Validate Password Component:
It was already there on previous versions but now this is not a plugin anymore but a component instead. For some statements like ALTER|CREATE USER, GRANT, SET PASSWORD, it checks the password of an user account against the policy that we defined (LOW, MEDIUM or HIGH) and rejects the password if it’s weak.

- InnoDB Tablespace Encryption:
It’s a 2-tier encryption architecture, based on a master key and tablespace keys. When a table is encrypted, a tablespace key is encrypted and stored into the tablespace header. When an user wants to access to his data, a master key is used to decrypt the tablespace key. So during the session I explained how it works, which are the requirements and how we can setup this feature. I also did a demo to show how we could extract some clear-text data without connecting to the MySQL Server in opposition to the fact that if encryption is activated that is not possible.
This feature is there starting from MySQL 5.7.11 but it helped me to introduce the next chapter.

- InnoDB Redo/Undo Log Encryption:
Redo log data is encrypted/decrypted with the tablespace encryption key which is stored in the header of ib_logfile0. Through a demo I explained, which are the requirements, how to setup it and what we have to think about before activating this option. And I showed how we could extract some sensitive data in the Redo Log Files if encryption is turned off.
IMG_9531
Same thing for the encryption of InnoDB Undo Log files, which can be activated with the system variable innodb_undo_log_encrypt.

- caching_sha2_password Plugin:
In MySQL 8.0 the new caching_sha2_password plugin makes the authentication strong as its predecessor (it still uses the SHA-256 password hashing method) but at the same time faster: a cache on the server side let the user accounts that already connected once bypass the full authentication.
Here the schema through which I explained the whole authentication process using RSA key pairs:
auth

A little conclusion

Participating to the DOAG and presenting there has been for me a very important professional, human and social experience. I went beyond my limits, I learned lots of news things thanks to the other speakers sessions, I met new people working on IT, had fun with colleagues sharing some spare time. This was my first participation to a conference , it will not be the last one. Why did not I start that before? ;)

Technical and non-technical sessions at the DOAG 2018

Yann Neuhaus - Thu, 2018-11-22 19:03

The amazing DOAG 2018 conference is over now. As every year we saw great technical as well as great non-technical sessions. What impressed me was the non-technical presentation “Zurück an die Arbeit – Wie aus Business-Theatern wieder echte Unternehmen werden” (back to work – how business theatres become real business company again) provided by Lars Vollmer. It was very funny, but also thought-provoking. Lars started with the provocative sentence that people do work too less. Not in terms of time, but in terms of what people do. I.e. lots of things they do looks like work, but actually is not. Like meetings, yearly talks, reports, presentations, etc. At one point Lars started talking about Dabbawalas in India to show that people may work with highest quality and totally independent without any hierarchical structure. It’s a very old concept. As lunch is too expensive in some Indian cities there is a service to bring the lunch in boxes from home to work. The people delivering the lunch boxes work totally independently, they have no boss and often are not able to read. But still, they are able to handover the lunch boxes from Dabbawala to Dabbawala until it finally arrives at the destination. The independent workers provide the service with an unbelievable high quality. I.e. out of 6 million lunch boxes only 1 is not delivered to the correct target. That’s impressive. See e.g. Wikipedia Dabbawala for it.

One of the technical sessions, which I appreciated to be able to attend was about “Oracle’s kernel debug, diagnostics & tracing infrastructure” provided by Stefan Köhler.
IMG_2040
That returned to mind my early days at Oracle Support with statements like


alter system set events '<EVENT_NUMBER> trace name context forever, level <X>';

However, the time of setting numeric events (e.g. 10046) is over as Oracle uses the UTS (Unified Tracing Service) for new events only and already maps some numbers to an Event++.

An example for UTS is:


alter session set events 'trace[RDBMS.SQL_Compiler.*][SQL: 869cv4hgb868z] disk=highest';

I.e. the section within the second brackets is the scope. In the example above that means create a 10053-trace on SQL_ID 869cv4hgb868z once that is parsed.

To make sure that events are populated from the SGA to all sessions PGA, Oracle introduced a new parameter “_evt_system_event_propagation” in 11g. Unfortunately that feature was broken in Oracle 12.2 (bug #25989066 & #25994378) and fixed in Oracle 18c. See also the comments in Blog Enable 10046 tracing for a specific SQL.

It’s sad that the conference DOAG 2018 is over, but we are looking forward to an interesting event in 2019. The world is changing to more Open Source software used in businesses and it will be interesting to see how Oracle (and also the DOAG) will react on that.

An error occurred (BucketNotEmpty) when calling the DeleteBucket operation: The bucket you tried to delete is not empty
Ok. This will not work. First get the objects:

$ aws s3api list-objects --bucket my.webtest

{

    "Contents": [

        {

            "LastModified": "2018-11-17T19:18:53.000Z",

            },

            "Size": 568

        }

    ]

}
and the bucket can be deleted:
$ aws s3api delete-bucket --bucket my.webtest

DOAG 2018 – Fazit: it’s not only about Oracle anymore

Yann Neuhaus - Thu, 2018-11-22 05:38

Amazing conference, amazing people and awesome party like every year  :mrgreen: and of course great networking like every year

DOAG2018_booth242
This year, I was quite impressed about the number of different technologies. Speeches were not only centered around the big red O. As already summarized, by my colleague Alain yesterday:

DOAG 2018 – Not only database – Docker and Kubernetes rule the world

Open Source RDBMS, containers and microservices are arising much more quickly than cloud computing even if, in some cases, both are linked/mixed together.

Of course, a lot of Oracle RDBMS presentations were really good and worth for partners as well as for customers. Some were centered around new features, the new release model but surprisingly in spite of the Cloud Computing trend all sessions about Oracle-, Linux basics were very popular. It makes me think that we are at the dawn of change on how Database Administrators are integrating RDBMS in the arising DevOps organization within their companies; DevOps requires stuff running fast without any long running complicated process.
It sounds like  the opposite of the database purpose which implies stability, performance, availability, etc.
So, what? if the developers are constantly looking for new technologies why shall we (DBAs) not look for alternative RDBMS? OpenSource RDBMS?

In my opinion, this is a quite good summary of what I felt during the conference and what I feel everyday at my customers as a consultant over the past five years.
Surprisingly, Paolo Kreth (Schweizerische Mobiliar) had a talk titled “Hilfe, die Open Source DBs kommen!” (Help, the Open Source DBs are arising) which exactly described that “feeling” from the opposite customer side with a real-life customer case.

DOAG_speech

Thanks to Paolo for sharing his mindset and the spirit of the IT @die Mobiliar. As a consultant, I fully agree and confirm the concept he introduced  are matching the reality with more or less success.

Basically, the more people are communicating, sharing expertise (whatever the budget), the more successful actions will be; This applies of course to DevOps but as well at entreprise level. Which indeed matches to our company values and that’s why we also have the label “Great Place To Work” for the second year in a row.
