New Technical article: Back Up a Thousand Databases Using Enterprise Manager Cloud Control 12c

Friends,

I am pleased to announce that a new technical article of mine has been published (January 2014) on the Oracle Technical Network.


Back Up a Thousand Databases Using Enterprise Manager Cloud Control 12c

This detailed technical article explains the set up and scheduling of full and incremental RMAN Database backups for  thousands of databases using Enterprise Manager Cloud Control (Enterprise Manager) 12c, and how this is done more easily and efficiently than the older, more time-consuming, manual method of performing Unix shell scripting, RMAN scripting, and cron jobs for each database to be backed up. 

And with the Database Group Backup feature new to Enterprise Manager Cloud Control 12c, it can be even faster to set up RMAN backups for multiple databases - even if there are thousands - that are part of an Enterprise Manager Database Group.

The article also highlights the advantages of using PDBs in Oracle Database 12c and backing them up using RMAN. RMAN cannot backup individual schemas, and it has always been difficult to perform point-in-time-recovery (PITR) at an individual schema level, since schemas can easily be distributed across multiple tablespaces. The advantage in using PDBs in a Container Database is that you can easily set up RMAN backups at the Container Database level, and yet perform PITR at the PDB level. This is a clear technical advantage of the Multi-tenant architecture of Oracle Database 12c.

The set up and scheduling of RMAN database backups forms a part of the Base Database Management features of Enterprise Manager that enables numerous customers to use Enterprise Manager 12c more and more.  In fact I had personally introduced Enterprise Manager to HDFC bank in India in 2007 for the purpose of their RMAN backups, they started using it for the first time, and today they are a DBaaS-Exadata reference customer who have presented in OOW for the last 2 years.

Regards,


Porus.
