i am using db2 udb v8.1 , so if parameter retain log records is off ,
i am assuing it use circular logging, in the doc it explains the log
records fill the log files and then overwrite the initial log records
in the initial log file, so if so, why we still have transaction log
is full error complaint? but if the log never clean up, so isn't it
will be problem that i have to keep increase the log file size, log
files numbers? our application only insert one record each time and
auto commit is on , but still has log full error.

Either increase the number of logs, commit more regularly, or configure your
system to rollback a single transaction from filling more than a specific
number of logs (max_log parameter).
Your final statement that you are committing after each insert is probably
incorrect.
BTW, using circular logging means you cannot roll forware after a restore,
meaning you have no proper recovery. It's OK for test systems with random
data, but should never be used in production.

It is OK to use circular logging in many data warehouse applications where
the data can be reloaded from an external source. If a full or incremental
offline backup is taken after each load, that is usually sufficient.
Obviously, in a transaction system, roll forward recovery is highly
desirable, if not mandatory.

it is circular logging. the insert, delete, update will always be one
row, with auto commit on, it sould be commit right away, i am using
prepare statement to do write, so it is ps.executeUpdate(); should
commit the write right away, and i did the test, i didn't have
connection.commit() to commit the change and i have the data in the
table. i still don't understand why i only do change on data one row a
time then commit still have the log full error

That would be read-only data.
BTW, many data warehousing applications have a multitude of data sources and
up to daily updates, so that "reloading" is not really an option. In our
case, even losing 24 hours of data is a major, "stay up until midnight" task
(and that was caused by a software bug we introduced in the update logic).

My contention was that you are not committing as you think you are. I
strongly suggest your using DB2 monitoring to figure out what is _really_
happening in the database. Staring at your code isn't going to tell you
thatm, especially with statements like "should commit", when it is apparent
from the error message that is isn't. You can debug your code later.

I would guess that you have other applications running, which caused logs to
be written but have not yet committed (or rolled back) the changes. Thus,
the logs are still active and cannot be reused.

I've said twice already: you need to monitor what's happening. Staring at
your source code or publishing your configuration here isn't going to help
you. You must use the DB2 monitoring facilities to find out what's
happening.

Hi xixi,
check with snapshot for all applications which application is using your
active log space. Furthermore, check your first active log file.
Possibly you have num_log_span or max_log set?
What is in your db2diag and notify log?
