Feature Overview
• Simplify Oracle policy management and administration
– Centralized Management of Backups
– Automatic Discovery of Oracle Instances
– Intelligent/Automatic RMAN Script Generation
– Job Management
– Simplified Schedule Types and Retentions
– Oracle Attributes
• Automatic Discovery
– NetBackup will automatically determine the Oracle Instances present in a Master
Server domain
– Discovery is performed every 4 hours in the background
– No additional configuration required
– Discovered instances can be viewed via the Instance Management UI
• Maintain Legacy Functionality
– Retain all pre 7.6 functionality
– Upgrade will not affect existing Oracle policies and processes
25
26. SYMANTEC VISION 2012
Oracle Intelligent Policy
• Intelligent Backup Features
– Dynamically generates RMAN scripts at run time
– Improved job management and details
– Optimized backups to dedupe storage devices
– Object based selection model for instances and backup selection
– Oracle tab for specifying RMAN parameters
– Supports streaming and snapshot methods
– Integrated with Oracle policy wizard
• FRA
– Enables RMAN backups of the Fast Recovery Area into NetBackup
– A Full schedule forces a backup of the entire contents of the Fast Recovery
Area
– Incremental schedule types will backup FRA contents that have not been
backed up yet
– Data can be restored from NetBackup via RMAN directly to the database
26
27. SYMANTEC VISION 2012
Oracle Intelligent Backup
• Scheduling
– Schedules types simplified
– Default Application Backup schedule has been removed
– Schedule type corresponds to the RMAN backup operation being performed
• Archive Redo Log Schedule
– Schedule dedicated to performing archive redo log backups
– Performs a stream based RMAN backup
– Frequency can be set in minutes
– RMAN archive redo log parameters can be specified in the Oracle tab
• Job Management/Details Improvements
– Parent child relationship maintained
– Better error handling
– RMAN script
– RMAN script output
– Database state and instance information
– Backup summary information
27
28. SYMANTEC VISION 2012
Oracle Intelligent Backup
• Optimized Dedupe Backup
– Agent will detect if a dedupe storage unit is being used and tune backup for optimized
performance
– Requirements
• Dedupe storage unit selected in policy
• Stream based backup (non-snapshot)
• Full schedule type
• Optimized Dedupe Backup Behavior
– Non ASM
• Incremental level 0 non-snapshot proxy RMAN backup
• Single RMAN channel allocated
• NB_ORA_PC_STREAMS set to number of parallel streams specified in policy
– ASM
• Incremental level 0 stream based backup
• Behavior influenced by FILESPERSET parameter specified in policy
• If FILESPERSET has not been overridden in policy, agent will set this parameter to 1 for the backup
• If FILESPERSET has been overridden to a value greater than 1, the agent will log a warning message in the job details
stating that setting FILESPERSET 1 will give better dedupe performance
