NEW QUESTION # 54
You have been asked to investigate why an Exadata Database Server stopped communicating on the client network for 10 minutes over the past weekend.
Which command would help investigate this?

  • A. # /opt/oracle.SupportTools/ibdiagtools/netcheck/runDiagnostics.pm -from <Fridays_Date>_17:00:00 -to <Sundays_Date>_23:59:00
  • B. $ ${ORACLE_HOME}/suptools/tfa/release/tfa_home/bin/tfact1 -from <Fridays_Date>_17:00:00 -to <Sundays_Date>_23:59:00
  • C. # /opt/oracle.ExaWatcher/GetExaWatcherResults.sh -from <Fridays_Date>_17:00:00 -to <Sundays_Date>_23:59:00
  • D. # /opt/oracle.SupportTools/exachk/exachk -from <Fridays_Date>_17:00:00 -to <Sundays_Date>_23:59:00

Answer: C

Explanation:
https://docs.oracle.com/en/engineered-systems/exadata-database-machine/dbmmn/maintaining-exadata-database-servers.html According to Oracle's documentation1, one of the utilities for diagnostics and repair of Oracle Exadata Storage Server is ExaWatcher, which collects operating system and network metrics on database servers and storage servers. The utility is located in the /opt/oracle.ExaWatcher directory1.
To investigate why an Exadata Database Server stopped communicating on the client network for 10 minutes over the past weekend, you can use the GetExaWatcherResults.sh script to collect and analyze ExaWatcher data for a specified time range1.
Therefore, the command that you should use to investigate this is:
/opt/oracle.ExaWatcher/GetExaWatcherResults.sh -from <Fridays_Date>_17:00:00 -to <Sundays_Date>_23:59:00

Which two statements are true about applying updates on Exadata systems?

  • A. When running a "yum update" for a new Exadata release, all other repositories should be disabled.
  • B. To speed up applying storage server updates in a rolling manner, updating two storage servers simultaneously is recommended.
  • C. Failed database server updates are rolled back to a working state on a previous release automatically.
  • D. For regular Exadata updates, yum automatically installs a non-UEK kernel, which can be selected to boot from grub.
  • E. Updating kernel and RDMA packages on storage cells should be prevented by excluding them with the yum -exclude option.
  • F. Failed storage server updates are automatically rolled back to a previous release.

Answer: C,D


NEW QUESTION # 56
What is the maximum DRAM capacity you can expand an X9M-2 DB Server?

  • A. 1024GB
  • B. 384GB
  • C. 768GB
  • D. 512GB
  • E. 1536GB
  • F. 2048GB

Answer: E

Explanation:
According to 1, Exadata X9M-2 Database Servers are based on Intel Xeon Platinum 8368Y processors with 32 cores and 768 GB of DRAM memory per server. This memory can be expanded up to 1.5 TB per server by adding 24 x 32 GB DIMMs. The DRAM memory is used for buffer cache, PGA, and other database purposes1. Exadata X9M-2 Database Servers also have 25.6 TB of Persistent Memory Acceleration (PMEM) per server, which is used for log writes and columnar data caching1. PMEM is a new type of memory that combines the speed of DRAM with the persistence of flash2. Exadata X9M-2 Database Servers are designed to run Oracle Database workloads with high performance, scalability, and reliability2


NEW QUESTION # 57
What does the following command do?
root@rul6 -]# for j in {01..23} ; do ipmitool sunoem cli "set /SP/network/test ping=192.168.1.1$j'' ; done

  • A. Verifies that the ILOM management network is working before installation of all storage and database servers in a full rack Exadata X9M-2, run from the first database server.
  • B. Verifies that the ILOM management network is working after OEDA configuration has completed for all storage and database servers in a full rack Exadata X9M-2, run from the first database server.
  • C. Sets the test address for the RoCE network for all storage and database servers in a full rack Exadata X9M-2, run from the first database server.
  • D. Sets the address for each storage and database server's /SP during installation to enable ping testing from the management network, run from the first database server.

Answer: A

Explanation:
The given command uses a for loop with ipmitool to issue ping commands sequentially to a range of IP addresses in the management network:
for j in {01..23}; do ipmitool sunoem cli "set /SP/network/test ping=192.168.1.1$j"; done This script verifies the connectivity of the ILOM management network before the Exadata installation. Each server's Service Processor (SP) is tested for reachability, confirming that the management network setup is operational across the full rack .


NEW QUESTION # 58

  • B. alert logs for Enterprise Manager
  • C. alert logs for the prod database instances
  • D. Enterprise Manager Alerts on the Exadata Storage Server Grid home page
  • E. Enterprise Manager Alerts on the ILOM home page for cell connectivity problems for the prod database instances

Answer: A,C

Explanation:
According to the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book and Resources, you can find diagnostic messages related to this problem in the alert logs for the ASM instances and the alert logs for the prod database instances. The alert logs for the ASM instances will provide information related to the offline asm disks, while the alert logs for the prod database instances will provide information related to whether the prod database instances are connected to the ASM instance or not.
