Cause

The Enterprise Server’s Cloudscape database is corrupt, preventing successful archiving.

Resolution

Attempt to recover the Cloudscape database. If recovery fails, delete or rename the database folder to allow automatic recreation.

Steps to Recover Database:

1. Stop the Enterprise Server station.
2. Open the Niagara console.
3. At the prompt, type:

   dbadmin "station name" recover
   

4. Restart the station and verify connectivity.

If Recovery Fails:

1. Stop the station.
2. Locate the app folder under the station directory.
3. Delete or rename the folder (e.g., add .old suffix).
4. Restart the station.
   • The Cloudscape database will be automatically re-created.
   • Confirm the database status shows “is connected.”
