7. Structured Data Validation

When the –SCAN or –FASTSCAN options are not specified, FCHECK

performs structured data validation.

FCHECK will prompt DP2 to examine each block to ensure a proper

structure, which must be consistent for the file or table type. If the –

NOBTREE option is not specified, DP2 examines key-sequenced B-tree

structures to ensure that the B-tree is consistent.

DP2 examines the file or table sequentially, and preempts the data

validation if higher priority work is present. FCHECK uses the –RATE value

to pause between preemptions to limit the impact on active production.

When DP2 encounters errors, EMS events are generated, and FCHECK

reports the details of the errors.
