Deleting delta members

A distinction should be made between logical and physical deletion:

• Logical deletion

  This merely deletes the entry from the directory. The records and the relationship with the predecessor member remain intact.

• Physical deletion

  Controlled by the DESTROY-DATA operand (it must be specified when the member is included) the storage space allocated to the member is overwritten with binary zeros.When used for delta members this operand will only become active once the last member of the delta tree is deleted. Specification of DESTROY-DATA=*YES for a member suffices to delete the entire container.
