  • Understand ASM Concepts and Architecture
  • Explain the role and benefits of Oracle ASM in storage management.
  • Comprehend the architecture, components, and operational principles of ASM.
  • Install and Configure Oracle ASM
  • Set up Oracle Grid Infrastructure for standalone and clustered environments.
  • Create and configure ASM disk groups.
  • Administer ASM Environments
  • Manage ASM instances, disk groups, files, and directories.
  • Perform storage management operations, including resizing and rebalancing.
  • Monitor and Optimize ASM
  • Use ASM tools to monitor performance and troubleshoot issues.
  • Optimize ASM configurations for efficient data access and resource utilization.
  • Enhance High Availability and Disaster Recovery
  • Leverage ASM to improve database availability.
  • Integrate ASM with Data Guard and RAC environments.
