In Oracle Day 2011 Istanbul, I gave a presentation about Oracle APEX. APEX is not well-known in Turkey, so I wanted to demonstrate how fast an APEX Application can be created, and prepared a video. Unfortunately there are no sound and annotations (because it’s planned to be shown with a narrator) but I think it’s still easy to follow.

First, I created a sample table with 4 columns. APEX created the sequence and trigger to populate numbers for the primary key. Then I created a sample application with an input form, and run it to enter sample data. At last, I checked if data is inserted into the table (by using APEX user interface). All of these steps were completed in 2 minutes and 12 seconds:

The presentation is in Turkish, so I don’t see any point in sharing it here but it’ll be shared in TROUG web site.

Oracle today announced availability of Oracle Solaris 11. Here are some key points about Oracle Solaris 11:

• Oracle Solaris Zones provides virtualization with lower overhead than VMware. New integrated network virtualization allows you to create data center topologies within a single OS instance with bandwidth control and monitoring.
• Oracle Enterprise Manager Ops Center provides enterprise wide, centralized control over hardware, OS and virtualization resources for Solaris 11, and it’s “included” in systems support (not requires an extra license).
• Oracle Solaris 11 is “secure by default”, it locks down services from first install and provides role-based root access.
• Oracle Solaris ZFS provides flash-enabled tiered storage pools, encryption and the scalability to store unlimited amounts of data. With Oracle Solaris ZFS deduplication, storage requirements in virtualized environments can be reduced by 10x.
• Oracle Solaris and Oracle software applications (such as Oracle Database 11g, Oracle Fusion Middleware 11g) are designed and tested together to provide faster fail-over, reliability and better application performance.

Yesterday, I presented at Oracle Day 2011 Istanbul. It was taken place in Swiss Hotel. I found opportunity to talk with my friends in TROUG and some readers of my blog. There was a huge interest to the event which contains 9 parallel sessions. As usual, our (TROUG) sessions were the favorites for the technical staff. Thanks to Oracle Turkey, we gave our presentations at one of the biggest conference rooms in Swiss Hotel, and we managed to fill the room.

Oracle Day 2011 Istanbul will be take place at Swiss Hotel, Istanbul on November 1. It’s the most essential, can’t-miss business and technology event of the year. You will get a chance to see the latest development in Oracle’s public and private cloud computing solutions and how the power of simplicity can change your IT to a force that drives business innovation.

You can find the event details and register at Oracle Events Website.

Thanks to Oracle Turkey, 6 members of TROUG will be presenting in Oracle Day 2011. I’m one of them. I’ll give a presentation about Oracle Application Express. I’ll try to give a brief introduction about Oracle APEX in 30 minutes.

Here’s the agenda (in Turkish).

Presentations of TROUG Members:

• Oracle Cloud G’nin Gidişi C’nin Gelişi by Zekeriya Besiroglu (Oracle ACE)
• Data Mining in 30 Minutes by Husnu Sensoy (Oracle ACE Director, DBA of the year 2009) – Have I mentioned that each presentation will take only 30 mins?
• Rapid Application Development Tool: Oracle APEX by Gokhan Atil (Oracle ACE)
• What has Exadata changed? by Ferhat Sengonul (Oracle ACE)
• Data Integration in Heterogeneous Environments by Gurcan Orhan – Gurcan is honored as Oracle Excellence Awards, Technologist of the Year 2011 Enterprise Architect.
• Forgotten Features by H. Tonguc Yılmaz (Oracle ACE)

6 presentations, 4 Oracle ACEs, 1 ACE Director, 1 Technologist of the Year: Too good to be true All presentations of TROUG members will be in Turkish. I believe that it will be a wonderful event for all Turkish Oracle users.

In my previous post, I tried to show how to install Enterprise Manager Cloud Control 12c, now I’ll show how to add target hosts to our Enterprise Manager system. I assume that you’re in a similar position (installed Cloud Control but haven’t added any target yet).

As you know, we have to install Oracle Management Agent to the targets to be able to manage them via our Enterprise Manager. In OEM Cloud Control 12c, we can “Add Host Targets Wizard” which is accessible from the web interface. We can manually enter required information of host or we can use auto-discovery method.

If we’ll use auto discovery, we need an active agent to discover targets in network. This agent can scan local services or network. “Nmap” is used for scanning network. Nmap requires root privileges to be able to use raw sockets for “Syn Scanning” (a method to detect open ports through firewalls). So we need to configure “privilege delegation” in the host of our agent (which we’ll use for scanning).
