TMSH0071E

Your CA 1 option MIXGDG is set to 'NO' and OCTLG is set to 'NO'. Generation datasets created on mixed devices may result in CA 1 not recognizing that a GDG(+1) on DASD has caused the roll off of a tape generation thus preventing CA 1 from expiring generation datasets accordingly.

Reason:

When you set CA 1 system option MIXGDG to 'No' and generation data sets are created on mixed devices, generations created on TAPE will not expire as expected.

Action:

This message is issued by the CA 1 Health Check component, which provides extensive detail on the problem encountered and the suggested response. The following actions and responses are documented for this check:

System Action: Processing continues, however, more generations are kept in the TMC and not expired.

Operator Response: Notify the systems programmer to change MIXGDG to 'YES'.

System Programmer Response: The TMS system option MIXGDG should be set to "YES" when OCTLG is set to "NO".

Setting MIXGDG to "YES" helps ensure that when generation data sets are created on mixed media, CA 1 will recognize the "roll off" for the tape data sets.

Problem Determination: You can use the CA 1 ISPF panels to display the current values of all your CA 1 options along with other information about the CA 1 Tape Management system.
