Precise Instantiation for Oracle
There are multiple instantiation methods available for instantiating an
Oracle target database. You can distinguish between these instantiation methods as
logical or physical. The following table describes the properties
of logical and physical instantiation methods:
| Logical Instantiation | Physical Instantiation |
|---|---|
|
Small Tables |
Large Database |
|
Flexible, useful for data manipulation and transformation |
Fast |
|
RMAN DataGuard-Split Split-Mirror Copy |
Oracle GoldenGate initial load and Oracle Data Pump are logical instantiation methods, ideal for small tables and scenarios requiring data manipulation or transformation during the load process. In contrast, Oracle RMAN provides a physical, block-based instantiation method, offering faster performance for large-scale data transfers.
