QUESTION 2
Examine the following values of the initialization parameters in the database having the SID ORCL:
BACKGROUND_DUMP_DEST=/u01/app/oracle/product/11.1.0/db_1/bdump USER_DUMP_DEST=/u01/app/oracle/product/11.1.0/db_1/udump
CORE_DUMP_DEST=/u01/app/oracle/product/11.1.0/db_1/cdump
DIAGNOSTIC_DEST=
The environment variables have the following value:
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/11.1.0/db_1
What is the location of the Automatic Diagnostic Repository (ADR) home?
A. /u01/app/oracle/product/11.1.0/db_1
B. /u01/app/oracle
C. $ORACLE_HOME/bdump
D. $ORACLE_HOME/log
Answer: B
Explanation:
The Automatic Diagnostic Repository (ADR) is a directory structure that is stored outside of the database. It is therefore available for problem diagnosis when the database is down. The ADR root directory is known as ADR base. Its location is set by the DIAGNOSTIC_DEST initialization parameter. If this parameter is omitted or left null, the database sets DIAGNOSTIC_DEST upon startup as follows:
If environment variable ORACLE_BASE is set, DIAGNOSTIC_DEST is set to the directory designated by ORACLE_BASE.
If environment variable ORACLE_BASE is not set, DIAGNOSTIC_DEST is set to ORACLE_HOME/log.
