Which of these formats represents the correct hierarchy for the ADR?
A.
<diagnostic_dest>/rdbms/diag/<dbname>/<instname>
B.
<diagnostic_dest>/diag/rdbms/<instname>/<dbname>
C.
<diagnostic_dest>/diag/rdbms/<dbname>/<instname>
D.
None of the above
Explanation:
The location of each ADR home is given by the following path, which starts at the ADR base directory:
diag/product_type/product_id/instance_id
As an example,
product_type: rdbms
product_id: DB_UNIQUE_NAME
instance_id: SID
For example, for a database with a SID and database unique name both equal to orclbi, the ADR home would
be in the following location:
ADR_base/diag/rdbms/orclbi/orclbi/
Similarly, the ADR home path for the Oracle ASM instance in a single-instance environment would be:
ADR_base/diag/asm/+asm/+asm/
