Oracle Code is back – Bigger and Better!

OTN TechBlog - Fri, 2018-02-16 16:24

2018 is yet another great year for developers! Oracle’s awesome global developer conference series, Oracle Code, is back – and it’s bigger and better!

In 2017 Oracle ran the first series of Oracle Code developer conferences. In over 20 cities across the globe the series attracted more than 10,000 developers from all over the world, providing them with the opportunity to learn new skills, network with peers and take home some great memories. Following the huge success, Oracle is about to run yet another 14 events across the globe kicking off in late February in Los Angeles. The great thing about Oracle Code, attendance and speaking at the conferences is fully free of charge, showing Oracle holding true to the commitment to the developer communities out there. Across four continents you will get to hear everything that is hot and top in the industry: Blockchain, Containers, Microservices, API Design, Machine Learning, AI, Mobile, Chatbots, Databases, Low Code Development, trendy programming languages, CI/CD, DevOps and much, much more will be right in the center of Oracle Code.

Throughout the one-day events, that provide space for 500 people, developers can share their experience, participate in hands-on labs, talk to subject matter experts and, most importantly, have a lot of fun in the Oracle Code Lounge.

Oracle Zip Labs Challenge

Want some bragging rights and to win prizes at the same time? Sign up for a 15-minute lab on Oracle Cloud content and see your name on the leaderboard as the person to beat in Oracle Zip Labs Challenge.

IoT Workshop

Interact and exchange ideas with other attendees at the IoT Workshop spaces. Get your own Wi-Fi microcontroller and connect to Oracle IoT Cloud Service. Oracle Developer Community is partnering with AppsLab and the Oracle Applications Cloud User Experience emerging technologies team to make these workshops happen.

Robots Rule with Cloud Chatbot Robot

Ask NAO the robot to do Tai Chi or ask "who brewed the beers"? So how does NAO do what it does? It uses the Intelligent Bot API on Oracle Mobile Cloud Service to understand your command and responds back by speaking back to you.

Dev Live

The Oracle Code crew also thought of the folks who aren’t that lucky to participate at Oracle Code in person: Dev Live are live interviews happening at Oracle Code that are streamed online across the globe so that everyone can watch developers and community members share their experiences.

Duplex RMAN backups between disk and tape

Yann Neuhaus - Fri, 2018-02-16 09:46

Below a workaround is shown how to “duplex” archivelog backups between disk and tape:

Backup on disk (normal way):

backup device type disk archivelog all;

 

Immediately  backup on tape:

backup device type sbt archivelog until time 'sysdate' not backed up 2 times;

 

This backup command backs up all archivelogs, that are not backed up twice, so all which are backed up with the first command. As in the first backup command a logfile switch is included, between the two backup commands, no logfile switch should occur, otherwise “duplexing” does not work. The until time clause in the second command is added to prevent RMAN from another logfile switch, which would lead to different contents of the backups. And this clause does not filter anything, because sysdate means date and time when issuing the command.

SQL Server Management Studio 17.4: Vulnerability Assessment

Yann Neuhaus - Thu, 2018-02-15 10:01

SQL Server Management Studio is a well know integrated environment used to manage SQL Server infrastructure.
This new version 17.4 can support SQL Server from 2008 up to 2017. It enhances existing features like Showplan, XE Profiler (complete list here) but also add an interesting one which is the Vulnerability Assessment.

Vulnerability Assessment will scan a database in order to help you to track security holes and deviations. Rules to define those deviations are based on Microsoft SQL Server best practices.
Let’s have a look to this new feature.

Once SSMS 17.4 installed, just choose the database you want to scan, right click on the database and select Task, Vulnerability Assessment and Scan For Vulnerabilities…:

VAss1

Select where you want to save the scan report and click OK:

VAss2

Once you clicked OK the scan is starting:

VAss3

At the end of the scan a Vulnerability Assessment Results is displayed:

VAss4

The report is displayed in a Management studio pane with the number of checks that have been run, how many issues have been found with different level of risk from Low to High and provide also some links about SQL Server security best practices.
Review all failed checks to validate that there are really security issues for your environment and go through results.
For each failed issue you will have a description of the issue, the impact, also the rule query applied and a possible remediation script:

VAss5

There is also a possibility to accept results even if there are considered as Potential Risk as a baseline. This will validate results that match the baseline.

VAss6

Once issues are solved or Baseline settled, the Vulnerability Assessment can be run again to see the result of the performed actions:

VAss7

This new feature integrated in Management Studio gives the ability to check that all your databases have a good level of security but also to keep this level.
Great new feature ;-)
