Configuring the Directory Structure for the Shares
■
Load balance Oracle RMAN channels evenly across ZFS Storage Appliance shares and
controllers.
To optimize buffering of the Oracle RMAN channel to the ZFS Storage Appliance, you can
tune the values of several hidden instance parameters. For Oracle Database 11g Release 2, the
following parameters can be tuned:
■
For backup and restore set:
■
_backup_disk_bufcnt=64
■
_backup_disk_bufsz=1048576
■
For image copy backup and restore:
■
_backup_file_bufcnt=64
■
_backup_file_bufsz=1048576
For additional information about tuning these parameters and tuning equivalent parameters for
earlier versions of the Oracle Database software, see Article ID 1072545.1: RMAN Performance
Tuning Using Buffer Memory Parameters) at My Oracle Support (https://support.oracle.
com).
Oracle Direct NFS (dNFS) is a high-performance NFS client that delivers exceptional
performance for Oracle RMAN backup and restore operations. dNFS should be configured for
customers seeking maximum throughput for backup and restore operations.
