The Purge Settings define the configuration parameters to manage the archiving and purging of FlexDeploy execution data from the database repository, and purging of the artifacts stored in the artifacts repository.

Property	Description
Purge Enabled	Indicates whether the purge process is enabled
Retention Days (Operational)	How many days of execution data to keep in the operational tables
Retention Days (Artifacts)	How many days of artifacts to keep in the file system
Keep Count	How many project versions to keep for each environment/instance regardless of `Retention Days (Operational)`
Keep Success Count	How many successful project version builds to keep regardless of `Retention Days (Operational)` (Note: this is a global setting and not specific to an environment/instance)
Keep Failed Count	How many failed project version builds to keep regardless of `Retention Days (Operational)` (Note: this is a global setting and not specific to an environment/instance)
Retention Days (Archive)	How many days of execution data to keep in the archive tables
Retention Days for Logs	How many days of execution data to keep in the log tables
Number of successful pipeline executions to keep	Number of successful of running pipeline executions to keep in operational tables.
Number of unsuccessful pipeline executions to keep	Number of aborted, failed , skipped, or out-of-date pipeline executions to keep in operational tables.

Purge Rules

Any workflow execution that is the last successful deployment to an environment is automatically excluded from the purge.
The three KEEP related parameters override the DAYS parameter (i.e. if Retention Days (Operational) is 1 day, anything that was deployed more than 1 day ago AND is one that needs to be kept to satisfy the KEEP parameters will be excluded from the archive/purge).
The Retention Days (Artifacts) only affects the removal of the artifacts from the file system. There is no archive of artifacts. The KEEP parameters will again override the artifact retention days. When the artifacts have been purged, a red circle will appear on the project version (as shown in figure 17.28) indicating that the artifacts have been purged. This project version will also no longer be available to deploy to any environment. To redeploy this version, the version of the source would need to be retrieved from source code repository (like SVN) in use and taken through the build/deploy cycle again.
The Retention Days are based on the first date it finds in this sequence: End time of the workflow execution, start time of the workflow execution, created time of the workflow execution, requested start time of the workflow request, or the created time of the workflow request.

Examples of configuring the purge

Scenario 1: Retain the last 3 successful builds in each environment/instance and keep the last 12 successful builds and last 2 failed builds overall. Artifacts will be purged from the file system after 15 days and execution data will be archived after 30 days. Data will remain in the archive for 365 days.

Understanding the purge KEEP parameters

Project Deployments:

Environment	DEV	QA	PROD
Project Versions	v9 (Failed)
	v10	v10	v10
	~~v11~~	~~v11~~	~~v11~~
	~~v12~~	~~v12~~	~~v12~~
	v13	v13
	~~v14~~	~~v14~~
	v15	v15
	v16
	v17
	v18 (Failed)
	v19

Properties:

Property	Value	Versions Retained due to property value
Keep Count	2	v11, v12, v14, v15, v17, v19
Keep Success Count	4	v15, v16, v17, v19
Keep Failed Count	1	v18
DEPLOYED TO AN ENVIRNOMENT	AUTOMATIC	v12, v15, v19

In this example, the only project versions that will be checked against the Retention Days would be v9, v10, and v13. Those three versions will only be purged/archived in they are older than the retention days parameters.
