4.1.1 Database backup time: RMAN full backup
The time necessary to create the full backup of our test database (while under TPC-C transactional
load) is shown below.
RMAN Full Backup Duration

Size (GB)
Time to create full backup 54 150
4.1.2 Performance impact: RMAN full backup
Figure 4 shows a composite chart illustrating the incremental impact on CPU utilization, database
response time and transactions per second (TPS) caused by RMAN backup processing.
