QuestionQ22

Backup and Restore

An administrator has configured SnapMirror active sync to protect Oracle databases between data centers. Multiple databases are stored on each LUN. A database administrator (DBA) asks the administrator to restore one database on the source cluster.

Which two parameters must the DBA provide?

Choose two
  • A byte count
  • B byte-range lock
  • C starting byte offset
  • D ending byte offset
Explanation

A partial LUN restore for a database stored alongside other databases requires the data range to be specified by its starting byte offset and byte count. This operation is supported for SnapMirror active sync volumes and preserves the rest of the LUN data.
