METHOD FOR CHECKING TABLESPACES INVOLVED IN REFERENTIAL INTEGRITY

摘要

A recover or reload utility determines if a check utility is to be executed. If a check utility is to be executed, the recover or reload records the dependent tablespace names to virtual storage allocated to a job step (1040) instead of to virtual storage allocated to a subtask (1050). After the recover or reload performs its function, if a check utility is next, the database operating system will not freemain the virtual storage (e.g., data area) into which the recover or reload utility has recorded the names of the dependent tables when the subtask ends. Upon termination of the recover or reload utility, the persistent data area is available for the check utility to use.
