In a Sysplex environment, use a shared SCDS for systems that have like processing requirements. For example, you might want to have all production systems sharing a single SCDS and all development or test systems sharing another SCDS.
Business Value:
This allows for more efficient use of resources as requirements for retention of SMF data and storage media can be quite different between environments. A production environment might have a five year retention requirement, a duplexing requirement, offsite storage, and use of high capacity tape drives, while a development or test system may only require thirty days for retention and use of DASD as the storage medium for history file data.
Additional Considerations:
Avoid implementing CA SMF Director for systems that are infrequently used, if you are required to do so it is suggested that these types of systems have a separate implementation of CA SMF Director with a non-shared SCDS.
