I am now a pilot!

Dear readers,

Oracle 12c Installation on Oracle Linux 6

Dear readers, I decided to finally get around to installing Oracle 12c (12.1.0) on Oracle Linux 6 today. One key difference is the increased disk space requirements from 11g to 12c for the basic database configuration. I recall that 11gR2 requires almost 4GB of disk storage space. Now, (more...)

End of 2012

Year in review As we end 2012, in closing I have not posted much due to work and many activities wrapping up the year. My new Oracle R12 EBS book is available and ready for folks to learn the tips and tricks for Oracle R12 Financials from Oracle Press.

Quick tip: Cloning Oracle 11gR2 RAC node in Oracle VM 3.0.3

Oracle VM 3.0.3 Server and Manager provide you with the ability to clone virtual machines quickly and easily. However, as of yet, there is not live hot clone facility available. The Oracle RAC VM must be powered off before you perform the clone operation.

There are two options available for cloning within Oracle VM: simple clone and advanced clone. Simple clone takes a quick snapshot of the VM to be copied to the new clone. Advanced provides you with the ability to create a custom clone process based on a menu driven GUI that you can create based (more...)

Uploading templates for OVM 3.0.3 to ftp server

Dear readers,

Its been a while since I've blogged due to many busy demands between work, finishing a new Oracle book and scuba diving. Recently, I setup a new Oracle VM 3.0.3 environment and the interface and tools have changed quite a bit since I last worked with OVM 2.2 version. One challenge is that now in OVM 3.0.3 you have to upload the VM templates via a web http or ftp server and no longer can you copy the Oracle VM templates over to the /OVS/seed_pool directory on the OVM server. In my case, (more...)

Howto- Install Oracle 11g Grid Control Enterprise Manager (OEM) Server

With the new features for Oracle 11g Grid Control Enterprise Manager (OEM), it is valuable tool now for managing large Oracle environments. I recall from Oracle 9i OEM days that it was a buggy tool and back then years ago, I used SQL*Plus and command line tools. However, in 11gR1, OEM has emerged as an excellent monitoring tool. I still use command line tools most of the time but for monitoring, its a great product. With that said, let's get started in building a new Oracle11gR1 Grid Control Enterprise Manager (OEM) environment on Linux!
