How can you detect the cause of the degraded performance? A. Enable Memory Access Mode, which reads performance data from SGA. B. Use emergency monitoring to fetch data directly from SGA analysis. C. Run Automatic Database Diagnostic Monitor (ADDM) to fetch information from the latest Automatic Workload Repository (AWR) snapshots. D. Use Active Session History (ASH) data and hang analysis in regular performance monitoring. E. Run ADDM in diagnostic mode. Correct Answer: B Section: (none) Explanation

Which three storage options support the use of HCC? A. ASM disk groups with ASM disks consisting of Exadata Grid Disks. B. ASM disk groups with ASM disks consisting of LUNS on any Storage Area Network array C. ASM disk groups with ASM disks consisting of any zero padded NFS-mounted files D. Database files stored in ZFS and accessed using conventional NFS mounts. Real 11 Oracle 1z0-060 Exam E. Database files stored in ZFS and accessed using the Oracle Direct NFS feature F. Database files stored in any file system and accessed using the Oracle Direct NFS feature G. ASM disk groups with ASM disks consisting of LUNs on Pillar Axiom Storage arrays Correct Answer: AEG Section: (none) Explanation Explanation/Reference: Explanation: HCC requires the use of Oracle Storage Exadata (A), Pillar Axiom (G) or Sun ZFS Storage Appliance (ZFSSA). Note: * Hybrid Columnar Compression, initially only available on Exadata, has been extended to support Pillar Axiom and Sun ZFS Storage Appliance (ZFSSA) storage when used with Oracle Database Enterprise Edition 11.2.0.3 and above * Oracle offers the ability to manage NFS using a feature called Oracle Direct NFS (dNFS). Oracle Direct NFS implements NFS V3 protocol within the Oracle database kernel itself. Oracle Direct NFS client overcomes many of the challenges associated with using NFS with the Oracle Database with simple configuration, better performance than traditional NFS clients, and offers consistent configuration across platforms. QUESTION 15 In your multitenant container database (CDB) containing pluggable databases (PDB), users complain about performance degradation. How does real-time Automatic database Diagnostic Monitor (ADDM) check performance degradation and provide solutions? A. It collects data from SGA and compares it with a preserved snapshot. B. It collects data from SGA, analyzes it, and provides a report.
