Your database Machine has the exachk utility pre-installed and you decide to use it periodically, to
validate the installation against Oracle’s recommended best practices.
Which two actions could you take to do this?
A.
Use a cron job on a database node to run it at regular intervals.
B.
Rut it once from a database node and it will then perform periodic monitoring automatically.
C.
Use a cron job on each cell to run it at regular intervals.
D.
Run it once on each cell and it will then perform periodic monitoring automatically.
E.
Create a Job in Enterprise Manager to run the exachk utility at regular intervals.
Explanation:
Note:
*Oracle Exadata Database Machine Cells are added as targets during the database machine
discovery workflow and are grouped automatically under the group Exadata Grid.
Based on the Exadata Grid group, a group of Exadata cells can be managed together through
Enterprise Manager Cloud Control 12c.
A & E
A, E
a b
for b to correct we need to start exachk daemon
A e
AE
A is right. exachk does not have autorun_schedule which is in orachk
B is wrong. exachk does not have autorun_schedule which is in orachk
C is wrong. exachk is run from db node
D is wrong. exachk is run from db node.
E is right. OEM can schedule exachk
So A.E. are correct
Actually newer version of exachk (or orachk) has AUTORUN_SCHUEDULE capability.
to run exachk regularly, you need to run it as deamon. So using cron is NOT OK.
in this case, B.E. are correct.
pre-installed.. and we are not upgrading to newer version
AE still holds good
Option B was not stated in the exam. There were only 4 options
