Compare I/O Activity Between Databases

The IO breakdown by individual databases chart lets you compare the I/O activity of your different databases.

1. Click the Group By list to select what metrics to group the databases by.

   • Life Cycle Status

   • Target Version

   • Cost Center

   • Host Name

   • Contact

   • Database Type

2. To view the 10 databases with the highest I/O activity, from the Group By list, select Top 10.
3. To view the disk I/O activity split on the basis of the pluggable databases, select Split by Pluggable Databases (Top 10).
4. Select the databases for which you want to view specific information.
5. To view the list of databases, and their relevant information like the DB type, disk I/O, change %, hostname, target version, life cycle, and cost center in a CSV format, click Download CSV.

The volume and percentage changes in the I/O activity are represented visually through the size and color of the cells, respectively. Cells that are larger have greater I/O activity than smaller cells. The largest cell would be that of the database with the highest I/O activity. The color of the cells is determined by the percentage change in the I/O activity during the specified time period.
