The CBROAMxx PARMLIB member contains one or more SETOAM statements. These statements contain keywords that you can use to tailor the object tape function. These statements can supplement or override information that was previously specified when the applicable Object or Object Backup storage group was defined using ISMF. Some keywords apply to all of the Object or Object Backup storage groups that use the object tape function, and others apply only to the group for which they have been explicitly specified.
For more information on changing the SETOAM values dynamically or defining the values when the CBROAMxx PARMLIB member is not used at initialization, see SETOAM statements for object tape storage and Updating SETOAM values.
