9.7 Managing Exadata Snapshots

To create and manage Exadata Snapshots, you need to perform these procedures:

• Creating Sparse Grid Disks
  
• Creating an ASM Disk Group for the Sparse Grid Disks
  
• Setting Up the Test Master
  You can create the test master using one of two methods:
• Creating Snapshots
  You can create an Exadata Snapshot of a pluggable database (PDB) or a complete database.
• Refreshing the (Read-only) Test Master Database
  To refresh a read-only test master database, it must be converted temporarily to a read-write test master.
• Creating a Snapshot Database from Another Snapshot Database
  
• Creating Sparse Test Masters from a Single Full Database Copy
  You can create multiple sparse test masters from a single copy of a full database.
• Creating Sparse Test Masters for PDBs
  This procedure creates a hierarchical snapshot tree or sparse test masters manually for a pluggable database (PDB) in an Oracle Multitenant database.
• Determining All Snapshots Associated with a Test Master
  Use this query to discover all of the children associated with a test master.
• Doing a Sparse Copy
