Last referenced date for a member in a PDS?

Hi All,
Is there any way to find out the last referenced date of a member in a PDS? It would be really great if somebody can help me out?
Our requirement is to find obsolete members in a PDS? So if we get the last reference date is two years back, we are considering it as obsolete. Hope my requirements are clear.

Hello,

If you have SMF records going back that far, you might be able to get what you want from old smf data (it is very high volume) and may take considerable system resources to process.

Suggest you talk with your system support people and see how long your smf files are kept.

How are these members used? If they are part of production jobs, more care would be needed, but if they are used by developers only, you might create a new backup pds with all of the members force it to migrate offline. Then delete all but the known needed members from the original pds and recover members if/as needed from the backup.

ISPF statistics show created date and latest changed date for PDS members but not last referenced date.

Dick,

SMF record type 14 / 15 does not go down to member level.

Hi Expat,

I guess i was hoping that the new smf record (type 42/sub-type 21) that tracks member deletion might have a companion that tracked reference.

Thinking about it more, i suspect that trying to record every member reference would consume an incredible amount of resources.

I should have looked deeper
