Book description

Implement a Centralized Cloud Storage Infrastructure with Oracle Automatic Storage Management

Build and manage a scalable, highly available cloud storage solution. Filled with detailed examples and best practices, this Oracle Press guide explains how to set up a complete cloud-based storage system using Oracle Automatic Storage Management. Find out how to prepare hardware, build disk groups, efficiently allocate storage space, and handle security. Database Cloud Storage: The Essential Guide to Oracle Automatic Storage Management shows how to monitor your system, maximize throughput, and ensure consistency across servers and clusters.

  • Set up and configure Oracle Automatic Storage Management
  • Discover and manage disks and establish disk groups
  • Create, clone, and administer Oracle databases
  • Consolidate resources with Oracle Private Database Cloud
  • Control access, encrypt files, and assign user privileges
  • Integrate replication, file tagging, and automatic failover
  • Employ pre-engineered private cloud database consolidation tools
  • Check for data consistency and resync failed disks
