Question 4: You plan to migrate an Oracle database that supports an online transaction processing (OLTP)
workload to your
Database Machine.
Following are details fior the source database:
Database version: 10.2.0
Byte order: Big Endian HP-UX (64-bit)
Database size: 24 TB
Storage: ASM with 1 MB allocation unit size
Which two are supported migration methods?
A. Physical migration using ASM online Migration
B. Physical migration using Transportable Database
C. Logical migration using Oracle Streams
D. Local migration using Oracle Streams
E. Logical migration using logical standby
Correct Answer: CE
Explanation:
There are several techniques fior migrating data to a Database Machine. Migration can be done
using Oracle Recovery Manager (RMAN) to backup firom traditional storage and restore the data
onto Exadata. Oracle Data Guard can also be used to fiacilitate a migration. This is done by first
creating a standby database based on Exadata storage. The standby can be using Exadata storage
and the production database can be on traditional storage. By executing a fiast switchover, taking
just seconds, you can transfiorm the standby database into the production database. This provides
a built-in safiety net as you can undo the migration very gracefiully ifi unfioreseen issues arise.
Transportable Tablespaces (B) and Data Pump may also be used to migrate to Exadata. Any
technique used to move data between Oracle Databases can be used with Exadata.
