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.

Here’s the agenda (in Turkish).

- 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?

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.
How to Deploy Oracle Management Agent 12c
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).

Installing Oracle Enterprise Manager Cloud Control 12c is easy and it’s already explained in a video at OTN website and MOS [ID 1359176.1]. Still, I wanted to create a step by step guide, and highlight the important points.
Here are the steps:
1) Installation of Oracle Linux (How to Install Oracle Linux 5.6)
2) Installation of Oracle Database (Repository Database): You can install one of the certified databases: 11.2.0.3, 11.2.0.2, 11.2.0.1, 11.1.0.7 and 10.2.0.5.
Do not forget to apply the latest PSU to the database. It is recommended that you do not use “memory_target” parameter with Enterprise Manager. Run the following commands and bounce the database:
|
1 2 3 4 5 6 7 8 9 10 |
ALTER SYSTEM SET pga_aggregate_target=1G SCOPE=SPFILE; ALTER SYSTEM SET shared_pool_size=600M SCOPE=SPFILE; ALTER SYSTEM SET job_queue_processes=20 SCOPE=SPFILE; ALTER SYSTEM SET log_buffer=10485760 SCOPE=SPFILE; ALTER SYSTEM SET open_cursors=300 SCOPE=SPFILE; ALTER SYSTEM SET processes=300 SCOPE=SPFILE; ALTER SYSTEM SET session_cached_cursors=200 SCOPE=SPFILE; ALTER SYSTEM SET sga_target=2G SCOPE=SPFILE; EXEC dbms_auto_task_admin.disable('auto optimizer stats collection',null,null); |
These are minimum values, you can set higher values according to your system resources. It’s also recommend to have at least 3 redo log groups sized 300M. Luckily, the installer will warn you about all these settings.

Yesterday (October 03), Oracle announced Oracle Enterprise Manager 12c (c for cloud). It’s the only complete management solution for enterprise cloud. Oracle Enterprise Manager is the first “12c” Oracle product. I’m sure that we’ll see more “12c” products in future.

I have noticed that Oracle Enterprise Manager Cloud Control is mentioned in all keynotes at Oracle Open World 2011. In my opinion, Oracle Enterprise Manager Cloud Control and Ops Center are the key components of the cloud environment.
