The DYNAMIC_LOGS parameter affects the server's behavior when a long transaction threatens to span the entire logical log before it has completed. Using DYNAMIC_LOGS, you can configure the server to handle this rare event by dynamically expanding the logical log.

Note that the long transaction high water marks (LTXHWM and LTXEHWM) remain enabled regardless of the value of DYNAMIC_LOGS.

To modify the DYNAMIC_LOGS parameter on the fly, use the onutil SET command. Example:

% onutil
1> SET DYNAMIC_LOGS 2;
