NEW QUESTION # 16
You are updating your Exadata X9M-2 Elastic Database Machine with 6 database servers and 12 High Capacity Storage Servers. You will be using patchmgr to apply updates across the entire machine while still maintaining database availability.
Assuming you are driving patchmgr from an external server, which statement is true about the execution phase?

  • A. patchmgr must be invoked with the -rolling argument. Each component type must be upgraded independently of the other.
  • B. patchmgr will apply patches in component groups consisting of 1 database server and 2 storage servers to minimize disruption.
  • C. patchmgr cannot apply updates in a rolling manner, you must manually apply patches with the dbnodeudpate and cellupdate tools if high availability is required.
  • D. patchmgr must be invoked with the -rolling argument with all database and storage servers listed in a single input file.

Answer: B

Explanation:
According to the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book [1], patchmgr can be used to apply updates in a rolling manner while still maintaining database availability. It will apply patches in component groups consisting of 1 database server and 2 storage servers to minimize disruption. This is done by invoking patchmgr with the -rolling argument and specifying the component groups in the input file.

NEW QUESTION # 18
You have been notified by your Network Administrator that an upstream switch has been replaced due to a hardware fault. Which command verifies that the client network on your Exadata X9M-2 Database Server is available via both client switches?

  • A. /opt/oracle.SupportTools/ibdiagtools/checkbadlinks.p1 -all
  • B. netstat -rn
  • C. cat /proc/net/bonding/bondeth0
  • D. ifconfig -a legrep "re0| re1"

Answer: C

Explanation:
According to Oracle's documentation1, the client network on Exadata X9M-2 Database Server is used for client access to the database servers using Single Client Access Name (SCAN) and Oracle RAC Virtual IP (VIP) addresses. To verify that the client network is available via both client switches, you can use the command:
cat /proc/net/bonding/bondeth0
This command displays information about the bondeth0 interface, which is used for the client network on Exadata X9M-2 Database Server2. You can check if both interfaces (eth0 and eth1) are active and connected to different switches3.
