Place logs on separate devices from table space containers
A basic strategy for all database storage configurations is to place the database logs on separate physical disk devices from the table space containers.
This strategy reduces disk access contention between input and output to the table space data sets, and input and output to the database logs, and preserves the mostly sequential access pattern for the log stream. Such separation also improves recoverability when log archival is employed.
