Single-user Environment

Local Mode

In local mode, the DBMS, which is loaded at program execution time, handles requests for database services, but does not support requests from multiple users.

A batch program that runs in local mode executes entirely in its own address space.

Local mode:

• Reduces system overhead for long-running batch jobs that tend to monopolize a database area
• Controls access from concurrently executing local mode applications and central version applications through physical locks on the area. Only one address space can update an area at one time.

Recovery in the event of abnormal termination is accomplished through manual recovery operations.
