# Dataset attribute groups VSAM criteria

This section describes the VSAM criteria for dataset attribute groups.

If a dataset attribute group definition contains an attribute associated exclusively with VSAM datasets, then the dataset group contains only VSAM datasets. For example, if you specify a value for CI_Size (control interval size), then the dataset attribute group consists of VSAM datasets that meet this and all other attribute criteria specified for the group.

The following attributes are associated exclusively with VSAM datasets:

- Associated_Entry_Name
- CI_Size Average_LRECL
- Maximum_Record_Size Maximum_Buffer_Size
- Compress_User_Data_Size Data_Component
- Index_Component Speed
- Recovery Reuse
- Unique Imbed
- Replicate Spanned
- Erase Page_Space
- Swap_Space VSAM_Dataset_Organization
- Percent_Free_CIs_per_CA Percent_Bytes_Free_in_CI

- Free_Bytes_per_CI Logical_Records
- Deleted_Records Inserted_Records
- Updated_Records Retrieved_Records
- Component_Free_Space Number_of_CI_Splits
- Number_of_CA_Splits Number_of_EXCPs
