Transaction Log Shrinking

Transaction Log Shrinking

Transaction Log Shrinking

I am having trouble shrinking the size of my transaction log.  I just started working here and notice the transaction log was never backed up.  Therefore it grew to 900 meg.  I cannot get the size to decrease and have about 800 Meg allocated that is not being used.  I have truncated the log and performed backups, but I still cannot get the database allocated transaction log file to shrink in physical size.... Any ideas would be appreciated.

RE: Transaction Log Shrinking

Click 'Truncate Log On Checkpoint' if you log is an issue - the only problem is that your log becomes useless to restore from...


RE: Transaction Log Shrinking

This drove me crazy (a short trip) before finding the "solution" on a newsgroup.  Run this from the Query Analyzer:

dbcc loginfo

If there is a "2" in the status column for the last record, it means that the last portion of the log is the active portion.  There is nothing you can easily do at this point to shrink it.  You can:

A) occasionally (daily, say) run dbcc shrinkfile (your_log) and/or the E/M's Truncate Log option, and wait for the active portion of the log to wrap back around during normal database activity, at which time the file will shrink, OR

B) write a loop in VB, FoxPro, or whatever to force a gazillion writes, thus speeding up the process in A.

Since its not an emergency, I'd choose A.
