Check the Chunk Free List with -ce and -pe

The -ce option checks each chunk-free list and corresponding free space and each tblspace extent. (See Next-Extent Allocation and Structure of the Chunk Free-List Page, respectively.) The oncheck process verifies that the extents on disk correspond to the current control information that describes them.

The -pe option performs the same checks and also displays the chunk and tblspace extent information during the check.

oncheck -ce
oncheck -pe

The -ce and -pe options also check blobspaces, smart-large-object extents, and user-data and metadata information in sbspace chunks. For information about using oncheck -ce and -pe, see managing disk space in the IBM Informix Administrator's Guide.
