You notice that a database node has hung, so you open a Service Request via My Oracle Support.
What diagnostic output will you send to My Oracle Support by default?
By default, the diagnostic output that you would send to My Oracle Support when a database node hangs is AWR (Automatic Workload Repository) report. AWR collects and maintains performance statistics and metrics. It is the primary tool used for Oracle database performance diagnostics and tuning.
Which two statements are true about troubleshooting failed patching activities? (Choose two.)
Failed OS patches on database servers can be rolled back, as this is a common procedure to revert unintended changes and restore functionality. Bundle patches applied using opatch auto have limitations in their rollback capabilities, specifically not allowing the rollback of only the database or the grid infrastructure home separately.
Your customer needs to ensure that their data is available on the Exadata machine during patches. The customer wants to be able to patch one server at a time but still be protected against single-node server failure.
What ASM redundancy level should they use?
To ensure data availability during patches and protection against single-node server failure, the ASM redundancy level should be 'High'. High redundancy (triple mirroring) ensures that there are three copies of the data, providing additional protection against multiple simultaneous failures. This means that even if one server is being patched and another server fails, the data will still be available and intact. High redundancy is the appropriate choice to meet the customer's requirements.
In which three ways can customers access the ILOM interface to manage the Exadata database and storage server hardware components? (Choose three.)
Customers can access the ILOM interface through the ILOM CLI interface via the management network, the ILOM Web interface via the management network, and by initiating a remote KVM session to the ILOM. These methods allow for comprehensive hardware management capabilities for both the Exadata database and storage server hardware components.
Which three tools can be used on a freshly re-imaged Exadata system to create, resize, or delete ACFS filesystems? (Choose three.)
On a freshly re-imaged Exadata system, three tools commonly used to create, resize, or delete ACFS filesystems are SQL*Plus and ASMCMD, ASMCA (ASM Configuration Assistant), and Enterprise Manager Cloud Control. SQL*Plus and ASMCMD provide command-line interfaces for managing Oracle databases and Automatic Storage Management Commands. ASMCA is a graphical tool provided by Oracle to manage ASM. Enterprise Manager Cloud Control is a comprehensive management tool that also supports management of ACFS filesystems. Enterprise Manager Express and RMAN are not typically used to manage ACFS filesystems, and OUI (Oracle Universal Installer) is primarily used for Oracle software installations, not filesystem management.
