Oracle 1Z0-1093-25 Exam Dumps

A . Execute ADDM (Automatic Database Diagnostic Monitor) analysis on a historical workload:

Performance Hub allows users to analyze performance data collected over time.

ADDM analysis provides insights into performance bottlenecks and recommendations for tuning.

C . Identify blocking sessions that are impacting database performance:

Performance Hub helps identify active blocking sessions, enabling quick resolution of performance issues.

It provides real-time and historical data for better troubleshooting.

Why the other options are incorrect:

B . Modify database parameters: Performance Hub does not have the ability to change database configurations directly.

D . Upgrade the database: Upgrades are managed through other tools, such as Database Upgrade Assistant (DBUA).

Oracle Database Management Documentation: Performance Hub

B . Recommendations for parameter tuning:

Database Management analyzes historical performance data and provides tuning recommendations.

These recommendations align with Oracle best practices to optimize database performance.

C . Comparison of parameter settings:

The service allows users to compare parameter configurations between different databases or across time points for a single database.

This is useful for identifying changes or discrepancies that could impact performance.

Why the other options are incorrect:

A . Automatic correction of parameters: Database Management does not automatically correct parameters; changes require manual intervention.

D . Lack of parameter management: Incorrect statement, as the service does offer parameter management features.

OCI Patching Process:

The Oracle Cloud Infrastructure console simplifies the patching process by integrating both database software and OS patching. The rolling update strategy ensures that one node at a time is patched, reducing the downtime associated with updating the entire cluster. The storage nodes are updated in a separate process to ensure data integrity and availability.

Why the other options are incorrect:

A: The OCI console updates both the OS and database software.

B: Updates are performed in a rolling fashion, not concurrently.

D: The OCI console handles OS patching for both compute and storage nodes.

Oracle Exadata Database Service Patching

Schema-less in NoSQL:

This means you don't need to define a rigid, fixed structure before data insertion. Each record can have its own structure, allowing flexibility for evolving data models. This is useful for unstructured or semi-structured data.

Why the other options are incorrect:

B: This describes relational databases.

C: This describes the structured nature of SQL databases.

D: While binary formats may be used, schema-less refers to the logical, not physical, structure.

B . Access OS metrics using the OCI Metrics Explorer within the OCI Console leveraging the Oracle Cloud Agent.

OCI Metrics Explorer is part of the OCI Monitoring service.

The Oracle Cloud Agent collects OS-level metrics and makes them available through the OCI Console.

Users can view metrics like CPU usage, memory utilization, and disk I/O.

E . Access OS metrics programmatically via the OCI Monitoring APIs:

The Oracle Cloud Agent collects OS metrics and exposes them via OCI Monitoring APIs.

This approach allows for automated data retrieval and integration with external monitoring tools.

Why the other options are incorrect:

A . vmcli utility: This is not a standard tool for accessing OS-level metrics on Base Database Service VMs.

C . Custom monitoring agent: While possible, it is not the primary or only method. Oracle Cloud Agent is the default tool.

D . Automatically pushed to the Cloud Exadata Service Dashboard: This statement is incorrect as OS metrics are available through OCI Monitoring.
