LOG LXX WRAP, DURATION 00:00:28 LEAST 00:00:28

Reason:

The message occurs each time the log area LXX wraps from its physical end to its physical start. The hh:mm:ss variables following DURATION and LEAST are timestamps that indicate hours, minutes, and seconds.

The time that the hh:mm:ss value displays following DURATION is the difference that is obtained by subtracting the timestamp of the first physical log record from the timestamp of the last physical log record. The duration includes the current contents of the LXX. The value is UNKNOWN if the time of the first physical log record is not known, such as right after upgrading from version 14.0 to Version 15.0. If the time has been 100 or more hours, the value is ++:++:++.

The time that the hh:mm:ss variable displays following LEAST represents the shortest wrap duration since the LXX was last initialized or extended. The LEAST time value can be more valuable in some calculations than the DURATION. The value is UNKNOWN if the time of the first physical log record is not known, such as right after upgrading from version 14.0 to Version 15.0. If the time has been 100 or more hours, the value is ++:++:++.

The value of this message lies in its giving the time that it takes to fill the LXX at its current size. This information can therefore help you tune the size of the LXX. The size of the LXX must be large enough to contain entire transactions when running with other work that is also logging maintenance. Additionally, the size of the LXX must be large enough to allow spilling the LXX at a frequency that is operationally desirable. If using the Change Data Capture (CDC) feature, take the following information into account. The size of the LXX for CDC usage must be large enough to allow the CDC Listener to keep up. The CDC Listener finds log records subject to CDC and preserves them to the CDC database.

Note: If this message becomes a nuisance, at MUF startup use the MUF startup option MESSAGE specified as MESSAGE NO,DB00321 to turn off the message. To stop or start message DB00321 after an executing MUF is enabled for processing, use the MESSAGE console-like command.

Action:

None. This message is for information only.
