The document describes troubleshooting an issue with Automatic Workload Repository (AWR) on an Oracle database. It shows the user receiving errors when trying to create AWR snapshots. The user then runs scripts to reinitialize the AWR schema, which drops and recreates all the necessary AWR tables. After this, AWR functions like creating snapshots work successfully.
