IT training are very important for an IT professional to keep up with the fast changing computer world. I welcome training for it’s an opportunity to go out of the four walls of the office. Reality never allows a leave at work to attend training due to the busy work load. An option for this case is to attend online training or i-Seminar.

I got invited to attend an hour of Oracle Free i-Seminar topic “Oracle RAC ONE Node”. It’s more of an overview or teaser of what good there is in Oracle RAC One Node.

It have features and benefits of Oracle RAC made available on a single-instance database.

Major benefits of having Oracle RAC One Node:

Computer server virtualization is a very hot topic in the IT industry. Database servers with Oracle RAC One Node running in virtual machines could improve availability and flexibility at lowest possible cost. It’s worth investing as it will make database management almost everything automated with little or no downtime at all.
