The CBROAMxx PARMLIB member contains one or more SETOSMC statements. The SETOSMC statement and its associated keywords determine the valid values of settings, at a global or storage group level, for OSMC processing. They associate an Object storage group with the Object Backup storage group that stores the first or second backup copies of objects. The SETOSMC statement determines which Object Backup storage groups contain the first and second copies of the objects that are associated with an Object storage group. If you do not provide a SETOSMC SECONDBACKUPGROUP statement, and specify a second backup group, OAM does not create second backup copies of objects. SETOSMC statements can also be used to enable and customize object recall to disk processing.

For more information on changing the SETOSMC values dynamically or defining the values when the CBROAMxx PARMLIB member is not used at initialization, see Updating SETOSMC values.
