Life cycle action storage optimizer

You can find the sample JCL M9STORO in the SAMPLIB PDS deployed during the BMC AMI Cloud agent installation or upgrade. The PWD parameter must point to the agent installation directory.

Life cycle action storage optimizer parameters

The following parameters are available:

Parameter	Format	Description	Default
--simulate	yes\|no	Specifies whether life cycle runs in simulation mode, meaning, no actual deletes occur	yes
--target	cloud	Specifies the target storage to be scanned Only cloud is supported.	cloud
--action	delete-expired\|storage-optimizer	Specifies the action to perform	delete-expired
--data-directory-range	nn-nn	Specifies the range of data directories scan within the object storage	0-9
--minimal-days-from-creation	nn	Specifies the minimal number of days for a cloud object to be considered as incomplete, thus making it eligible for optimization	5

Process output DDs

Storage optimizer opens three output DD files. The following table includes details about each DD:

Output DD name	Description
STDOUT	The life cycle storage optimizer output, including a periodic summary that is printed every five minutes
SYSOUT	The JVM output
SUMMARY	A list of Identified optimizable chunks to be deleted

Examples

Example 1

The sample JCL M9STORO, by default, is set to scan for resources older than 30 days in simulation mode only.

Example 2

The sample output below demonstrates how the STDOUT output DD look like when running the storage optimizer process.
