Hi All,
I need to reduce the log file size to be very small . At the moment , the current size is 14 GB .
I hv run : ALTER DATABASE ExampleDB SET RECOVERY SIMPLE
DBCC SHRINKFILE('ExampleDB_log', 0, TRUNCATEONLY)
but it only free up 1 GB
I also run
DBCC SHRINKFILE('ExampleDB_log', 1)
but it doest give me a result as expected.
What should I do ?

Why you want to shrink the log file?

Maybe its only shrinking 1 GB because that's all the free space available.

If you still want to shrink, take log backups and then you should shrink.

However, the log will grow back again when it requires more space.
