The -cs option checks sbspaces. The -ps option checks sbspaces and extents.

The -cS option validates and displays metadata for an sbspace.

The -ps option checks sbspaces and extents. If you do not specify the sbspace name, these options check all sbspaces.

The -pS option validates and displays metadata for an sbspace and also lists extents and header information for smart large objects.

If you do not specify the sbspace name, all sbspaces will be checked. The following example checks and displays metadata for test_sbspace: 
oncheck -ps test_sbspace

If you specify rootdbs as the sbspace name with the -cs or -ps options, oncheck checks the root dbspace.
