  • B. Executing /opt/oracle.supportTools/reclaimdisks.sh -free -reclaim on each Exadata X9M Database server is required to reclaim disk space and perform partition reconfiguration.
  • C. Do not proceed if the OEDA Validate Configuration File step displays an error message about missing files p6880880.zip.
  • D. It is required to install OEDA on the first new database server.
  • E. In order to configure the servers with Oracle Exadata Deployment Assistant (OEDA), the new server information must be entered in OEDA, and the configuration file must contain existing nodes.

Answer: A,E

NEW QUESTION # 72
Which two activities are supported on the storage servers in an Exadata Database Machine?

  • A. installing an alternative package manager
  • B. upgrading a device driver for hard disks when inserting a replacement disk after a hard disk failure
  • C. upgrading the Storage Server software package using rpm
  • D. configuring secure shell user equivalency for the cellmonitor user
  • E. changing the root password

Answer: D,E

Explanation:
According to the web search results123, the storage servers in an Exadata Database Machine are mainly used for processing data at the storage level and offloading some SQL operations from the database servers. Therefore, the two activities that are supported on the storage servers are:
1. changing the root password
2. configuring secure shell user equivalency for the cellmonitor user

NEW QUESTION # 73
What is the maximum DRAM capacity you can expand an X9M-2 DB Server?

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

Answer: F

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 # 74
Examine this list of software components:
1. Oracle KVM Guest
2. Oracle Enterprise Manager Agent (OMA)
3. ASM instance

5. Automatic Diagnostic Repository Command Interpreter (ADRCI)
6. CELLCLI
7. Cell Server(CELLSRV)
8. diskmon
9. Restart Server (RS)
10. Management Server (MS)
What is the correct location where these software components can run in the standard Exadata Database Machine deployment?

  • A. 1, 2, 3, 4, 5, 8, 9 and 10 run on the database servers; 5, 6,7, 9 and 10 run on the Exadata storage servers.
  • B. 2, 3, 4, 8, and 10 run on the database servers; 1, 5, 6, 7and 9 run on the Exadata storage servers.
  • C. 3, 4, 8, and 10 run on the database servers; 1, 2, 5, 6, 7 and 9 run on the Exadata storage servers.
  • D. 1, 2, 3, 4, 9 and 10 run on the database servers; 5, 6, 7, 8, 9, and 10 run on the Exadata storage servers.
  • E. 1, 2, 3, 4, 8 and 9 run on the database servers; 5, 6, 7, 9 and 10 run on the Exadata storage servers.

Answer: A

Explanation:
Oracle KVM Guest: This is a virtual machine that runs on top of Oracle Linux KVM hypervisor. It can be used to run Oracle Database or other applications on Exadata Database Machine2. Therefore, it runs on the Database Servers.
Oracle Enterprise Manager Agent (OMA): This is a software agent that communicates with Oracle Enterprise Manager Cloud Control and provides monitoring and management capabilities for Exadata Database Machine2. Therefore, it runs on both Database Servers and Storage Servers.
ASM instance: This is an instance of Oracle Automatic Storage Management (ASM), which is a volume manager and a file system for Oracle Database files. It manages disk groups that span across multiple Storage Servers2. Therefore, it runs on the Database Servers.
RDBMS instance: This is an instance of Oracle Database that processes SQL statements and executes transactions. It uses ASM disk groups to store data files, control files, redo log files, etc2. Therefore, it runs on the Database Servers.
Automatic Diagnostic Repository Command Interpreter (ADRCI): This is a command-line tool that enables you to view diagnostic data stored in the Automatic Diagnostic Repository (ADR). ADR is a file-based repository for database diagnostic data such as trace files, alert logs, etc2. Therefore, ADRCI runs on both Database Servers and Storage Servers, depending on where the ADR is located.
CELLCLI: This is a command-line interface that enables you to configure and manage Exadata Storage Server Software. It allows you to perform tasks such as creating disk groups, monitoring cell health, applying patches, etc2. Therefore, it runs on the Storage Servers.
Cell Server(CELLSRV): This is a process that runs on each Storage Server and handles I/O requests from the Database Servers. It implements Exadata Smart Scan , which offloads data-intensive SQL operations from the Database Servers to the Storage Servers2. Therefore, it runs on the Storage Servers.
diskmon: This is a process that monitors the status of disks and flash devices on each Storage Server. It reports disk failures and performs automatic disk reclamation2. Therefore, it runs on the Storage Servers.
Restart Server (RS): This is a process that manages automatic restarts of critical processes such as CELLSRV , MS , or OMA in case of failures. It also handles graceful shutdowns and startups of all processes on each server2. Therefore, it runs on both Database Servers and Storage Servers.
Management Server (MS): This is a process that provides management services for each server such as collecting metrics , logging events , executing commands from CELLCLI , etc2. Therefore, it runs on both Database Servers and Storage Servers


NEW QUESTION # 75
Which three statements are true about Oracle Configuration Manager (OCM) for an Exadata Database Machine?

  • A. It collects configuration information automatically.
  • B. It is mandatory to install OCM on all database servers.
  • C. It collects configuration information on demand.
  • D. Collected configuration information can be uploaded automatically to Oracle.
  • E. It is mandatory to install OCM on at least one database server.
  • F. Collected configuration information can be uploaded manually to Oracle.

Answer: B,E,F

Explanation:
According to the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book and Resources, OCM is mandatory to install on at least one database server and can be used to collect configuration information on demand. The collected information can then be uploaded either manually or automatically to Oracle.
