92. You executed the following commands in an RMAN session for your database instance that has
failures:
RMAN> LIST FAILURE;
After some time, you executed the following command in the same session:
RMAN> ADVISE FAILURE;
But there are new failures recorded in the Automatic Diagnostic Repository (ADR) after the execution of
the last LIST FAILURE command. Which statement is true for the above ADVISE FAILURE command in
this scenario?
A.It produces a warning for new failures before advising for CRITICAL and HIGH failures.
B.It ignores new failures and considers the failures listed in the last LIST FAILURE command only.
C.It produces advice only for new failures and the failures listed in the last LIST FAILURE command are
ignored

D.It produces an error with recommendation to run the LIST FAILURE command before the ADVISE
FAILURE command.

答案解析：

1、2窗口，首先里看一下文件的位置

sys@TESTDB> select file#,name from v$datafile;     FILE# NAME---------- --------------------------------------------------         1 /u01/app/oracle/oradata/testdb/system01.dbf         2 /u01/app/oracle/oradata/testdb/sysaux01.dbf         3 /u01/app/oracle/oradata/testdb/undotbs01.dbf         4 /u01/app/oracle/oradata/testdb/users01.dbf         5 /u01/app/oracle/oradata/testdb/example01.dbf         6 /u01/app/oracle/oradata/testdb/test1.dbf         7 /u01/app/oracle/oradata/testdb/test2.dbf7 rows selected.

2、 1窗口，做实验前先备份一下backup database,或backup tablespace test1和backup tablespace users，这里实验先会删除test1.dbf，后删除user01.dbf

全备份数据库

或者备份test1表空间，users表空间已经在91题备份过

RMAN> backup tablespace test1;Starting backup at 02-SEP-13using target database
