Back Up a Thousand Databases Using Enterprise Manager Cloud Control 12c [34676]
by Porus Homi Havewala

Porus writes, "Oracle has long supplied a powerful utility, Oracle Recovery Manager (RMAN), along with the database software install, which is used to backup and recover Oracle databases, either as a complete or incremental backup. The scripts are placed in a shell script wrapper at the Unix level, and then scheduled using the Unix cron job facility. These scripts need to be tested, verified and maintained.

While this task is manageable for one or two databases, the same task must be repeated with every new database or every new database server that is provisioned-and the time spent on setting up such backups increases correspondingly.

In this technical article, we will see how the DBA can set up and schedule RMAN database backups for thousands of databases using Enterprise Manager Cloud Control 12c more easily and efficiently than the older, more time-consuming, manual method of performing Unix shell scripting and cron jobs for each database to be backed up..."

Using Oracle VM Templates

by Olivier Canonge with contributions from Christophe Pauliat, Simon Coter, Saar Maoz, Doan Nguyen, Ludovic Sorriaux, Cecile Naud, and Robbie De Meyer

This hands-on lab demonstrates how to use Oracle VM Templates to virtualize and deploy complex Oracle Applications in minutes. Step-by-step instructions demonstrate how to download and import templates and deploy the applications, using an Oracle RAC template as an example.

The templates include full support for single-instance, Oracle Restart (Single-Instance High Availability [SIHA]), and Oracle Real Application Clusters (Oracle RAC) database deployments for both Oracle Database 11g Release 2 and Oracle Database 12c. The templates also support the Flex Cluster feature of Oracle Database 12c and Oracle Flex Automatic Storage Management (ASM), as well as automation for container/pluggable databases in Oracle Database 12c.

Next Virtual Sysadmin Day Is On Jan 28 [34106]
Tracks for Oracle Solaris, Oracle Linux, and Oracle VM

Rick writes, "OTN's next virtual sysadmin day is on January 28. It's four hours long, from 9:00 am - 1:00 pm PT.

This time we have a whole new set of hands-on labs for Oracle Solaris, Oracle Linux, and Oracle VM. Proctored, of course, which means you can ask questions. The labs in our previous virtual sysadmin day focused on the basics. These focus on using these technologies in real-world scenarios. Click on the Agenda tab in the registration page to see the labs.

The event is free, but you do need to register. And there's a little homework involved. Nothing too complicated. We just expect you to have VirtualBox installed and the proper images already imported before we begin class. Click on the the Instructions tab for more info..."
