Configuring Data Retention Time

Once data collection has begun, the Oracle Communications Session Delivery Manager server running Oracle® Communications Report Manager aggregates the data based on several default types of periodic data collection methods. Use this task if you want to modify the default data retention policy for retaining raw data and each aggregation time (hourly, daily, weekly, and monthly). Data and reports that exceed the retention times you configure are automatically purged from the system each night.

Note:

There is no maximum value for retention time. If you set the retention time to 0, data is not retained for that time period, and the data is purged once it is aggregated.

Caution:

Increasing retention times increases disk usage. Ensure that the host to which HDR data is being delivered has the disk capacity to store the required retention periods.

1. Expand Report Manager and click Retention Policy in the navigation pane.
2. In the Retenion Policy table, select retention times for raw data and aggregated data from the drop-down lists.
