Which two are true about Recovery Manager (RMAN) diagnostic message output? (Choose two.)
Which two are true about Recovery Manager (RMAN) diagnostic message output? (Choose two.)
RMAN error stacks should be read from the bottom up as that is the order in which errors are generated. The RMAN LOG command line clause causes output issued during RMAN command compilation to be written to a log file only.
Correct are B and E: [oracle@rac1 admin]$ rman target / log '/tmp/log.txt' RMAN> list backup summary; RMAN> exit [oracle@rac1 admin]$ cat /tmp/log.txt Recovery Manager: Release 19.0.0.0.0 - Production on Mon Jun 22 15:48:39 2020 Version 19.6.0.0.0 Copyright (c) 1982, 2019, Oracle and/or its affiliates.

Agree with B,E Here's the an additional reference https://docs.oracle.com/database/121/BRADV/rcmtroub.htm#BRADV89875 The sbtio.log contains information written by the media management software, not Oracle Database. Thus, you must consult your media vendor documentation to interpret the error codes and messages. If no information is written to the sbtio.log, then contact your media manager support to ask whether they are writing error messages in some other location, or whether there are steps you must take to have the media manager errors appear in sbtio.log. Read the messages from the bottom up, because this is the order in which RMAN issues the messages. The last one or two errors displayed in the stack are often the most informative.
agree with B,E
the correct answer is B and E because RMAN error messages read from bottom up and log option writes output to log files only.
I think it's BE.
RMAN error stacks goes from general to specific, or from consequence to a cause when read top-down. The root cause is always on the bottom.
B & D is correct
BE correct
i think be: https://docs.oracle.com/database/121/BRADV/rcmtroub.htm#GUID-3F0A6F9D-1FD0-4507-8E2B-B1A205690BCC
BE but sound that A is true too.
It's software vendor dependent: "If no information is written to the sbtio.log, then contact your media manager support to ask whether they are writing error messages in some other location" from https://docs.oracle.com/database/121/BRADV/rcmtroub.htm#BRADV89875
Option A looks valid too. https://docs.oracle.com/database/121/BRADV/rcmtroub.htm#BRADV012
I think B, D and F are correct
I think BD. B sure that is correct, the other i doubt between D or F, any suggestion?
D is incorrect, Rman's LOG parameter cause the output to be written to a log only
Finally BE. https://logic.edchen.org/3-ways-to-set-rman-log-location/
