| Zusammenfassung: | A logical record of a source logical page is moved to a space area or a deletion area in a destination logical page. The source logical page is sequentially set forward from the logical page immediately before the last stored logical page in a subrange. The destination logical page is sequentially set backward from the leading logical page in the subrange. When a logical record is moved, exclusive control is performed in logical page units only on the source logical page and the destination logical page. The access by online operations is not prohibited on other logical pages not exclusively controlled in the same subrange. |
