log grows after shrinking

I have truncated the log file and then used the DBCC Shrinkfile command to
reduce to physical size of the file. This seemed to work perfectly.
However, after a few days the transaction log file returns to its huge size
(8Gb). Has anyone else experienced this problem and if so can you suggest a
solution?
Thanks in advance, Simon.Simon
It sounds like you have your database in full recovery mode, but you are not
performing transaction log backups.
If you want to use your transaction logs as part of your backup and recovery
strategy, (recommended for production systems) you need to back them up
regularly. Something like every 15 or 30 minutes (or whatever is suitable for
your requirements) during your business day.
If you really do not want your transaction logs, set your recovery mode to
simple.
Hope this helps

the size of the data portion of your data files if you are doing regular
maintenance with the DB maintenance wizard. The reason is that the
Organization task will serially reorganize your data tables. The largest
table will dictate the amount of free space in your data file and the size
of transaction log for normal operations.
If you do not want your tranaction log to be bigger than this, you need to
be in SIMPLE RECOVERY or backup the tlogs frequently if in FULL RECOVERY or
BULK INSERT RECOVERY modes.
How big is your data files?
