Element Description Key Considerations
dbspace_number The number of the dbspace to check.  


Run this function to check each chunk-free list and corresponding free space and each tblspace extent. If you do not specify a dbspace number, all dbspaces are checked. The function checks dbspaces, blobspaces, smart-large-object extents, and user-data and metadata information in sbspace chunks.

This function is equivalent to the oncheck -ce command.


The following example checks the extents in the dbspace with the number 2:
EXECUTE FUNCTION task("check extents",2);
