Database protection using SnapValidator

The following section describes how Data ONTAP provides Oracle database protection using SnapValidator.

• What SnapValidator checks
  The SnapValidator software implements Oracle H.A.R.D. checks to detect and reject invalid Oracle data before it is written to the storage system.
• How SnapValidator checks are set when you upgrade or revert Data ONTAP software
  Data ONTAP puts SnapValidator options in a known state when you upgrade or revert the Data ONTAP software.
• Preparing a database for SnapValidator
  Before you can use SnapValidator to protect the Oracle database, you must prepare the database for SnapValidator checks in a test environment to avoid disruptions to the production environment.
• Implementing SnapValidator checks
  You can protect a new Oracle database stored on a storage system by implementing Oracle Hardware Assistant Resilient Data (H.A.R.D.) checks to detect and reject invalid Oracle data before it is written to the storage system.
• Disabling SnapValidator
  You can turn off SnapValidator checks at the volume level or at the LUN level if checking for invalid Oracle data is no longer a priority.
• Troubleshooting invalid data error messages
  You should check that you configured SnapValidator correctly before investigating other reasons when SnapValidator checks return error messages.
