Log file is Full: How to prevent it happening?

"The log file for database 'DW_BackRoom_RT' is full. Back up the
transaction log for the database to free up some log space."
Now I only know this way to deal with that manually,
Step1. in option , chance Recovery model from FULL to Simple.
Step2: go to task to manually shrink the log file
Step3: Change recovery model back from simple to FULL.
But by this way, I could get same problem again, the log file is fill,
and need free up.
Could you give an idea how to prevent this from happening? what and
how should I do?
Thanks a lot in advance for your help.
If you are periodically wiping the transaction log, then it sounds like it
is of no importance to you so I'd recommend leaving in simple recovery mode.
If you decide that the log is needed for DR, set up a backup plan which
includes full database backups and regular log backups.

|||Hello,
If the data is this database is not critical/non production you can set the
recovery model to SIMPLE. THis will make sure that after
each checkpoint data will be writtent o disk and clear the transaction log
file. Incase if the data is critical keep the Recovery model
to FULL and make sure that you schedule a transction log backup (BACKUP
LOG). SO after each transction log backup the
LDF file will be cleared. THis will help you to restrict the growth of LDF
file and log backups will help you to recover the
database if needed as welll as you can perform Point_IN_Time recovery if
needed.
Take a look into Recovery models in Books online.

Log file for database "xxx" is full

I seen the error message "Log file for database xxx is full. backup the
transaction log for the database to free up some log space.",
but I already checked the automatically grow file and unrestricted file
growth, and the server has still near 2GB free space, why the error still
pop-up? I have set the By percent property of the File growth to 15, but in
fact what is the number means?
By percent property means that the file will grow by 15% each time it needs.
As to why it doesnt grow, did you check the windows side of things? Policies
and such limitations to file size.

|||grow by 15%, but I don't know the x in x = x + 15%! what is the x come from?
I see the space allocated column is 110, is this means the file will grow by
110 * 15% each time?

It will grow by x * 0.15 each time. So if you have 100, next value is 115,
after that is 115 + (115* 0.15)

The problem can actually also occur if you server doesn't grow the log
file fast enough. If it happens quite often, I'd consider increasing the
log size manually and then expanding it with e.g. 50% or 100 %. By doing
this it will take a while before it has to grow again. You could also
try to set the "auto grow" option to grow e.g. 100 MB at the time rather
than a percentage.
You don't mention anything about your backup strategy, but it could be
that you need to backup you log file in order to re-use the space
already claimed by the log file.
