Advantages of Cloning a Database Using the EVA Snapclone
Technology Compared to Using the Oracle Recovery Manager
Feature
The Oracle Recovery Manager (RMAN) supports the DUPLICATE command option to clone
the Oracle database. The DUPLICATE command performs the following tasks:
• Determines the nature and locations of database backups
• Allocates an auxiliary channel for the auxiliary instance
• Restores the datafiles and archived redo logs to the auxiliary instance
• Builds a new auxiliary control file
• Performs an incomplete recovery for the clone
• Resets DBID for the clone
• Opens the clone with resetlogs.
The EVA Snapclone cloning feature enables you to avoid lengthy backup and restore
procedures, which the RMAN DUPLICATE command requires.
