Recovery Writer Process (RVWR)

Flashback Helper — Rewinding Database Time ⏪

🔄 What is RVWR?

The recovery writer process (RVWR) works with the Flashback Database feature. It reads flashback data from the flashback buffer in the system global area (SGA) and writes it to flashback logs.

🛠️ What Does RVWR Do?

  • RVWR undoes transactions by moving the database state backward in time.
  • It helps the database return to a previous point, using stored flashback logs.
  • This makes it possible to recover from errors or unwanted changes without restoring backups.

⚙️ Key Details

  • RVWR can run as a thread or as an operating system process.
  • It operates only if Flashback Database is configured and enabled.

💡 Why RVWR Matters

  • Enables fast recovery to an earlier state without full database restore.
  • Minimizes downtime by avoiding complex recovery operations.
  • Works silently in the background, continuously maintaining flashback logs.
