Is it possible to shrink a SQL server log file?

Is it possible to shrink a SQL server log file?

But you can reclaim this excess space by shrinking SQL Server log file. The process of shrinking SQL log files can be executed only if database is online and atleast one Virtual log file is set to free. In some cases, shrinking the log may not be possible until after the next log truncation.

Why is MY SQL log file so big?

Sometimes the SQL users moves their SQL database pages from one location to another location, in file the unoccupied space comes closer to the front of the file from the end and this makes transaction log file large. But you can reclaim this excess space by shrinking SQL Server log file.

Do you have to truncate or shrink a file?

If you are truncating manually and shrinking you will not be able to recover point in time. Moreover files will grow again and you have to keep doing this manually all the time. Once you pre grow your file based on your usage and set up scheduled transaction log backup you should not have to adjust file size, truncate manually or shrink file.

Can You shrink a file to recover a point in time?

Shrink will not help as your logs are not being truncated. If you are truncating manually and shrinking you will not be able to recover point in time. Moreover files will grow again and you have to keep doing this manually all the time.

How can I consolidate multiple log files into one?

I have run multiple DBCC SHRINKFILE commands on both of the LOG files. The most recent attempt was DBCC SHRINKFILE (MasterScratchPad_X1_Log, 0) yet result is as above. How can I accomplish this goal of having just one .LDF? I cannot find anything on how to delete the one with fileid of 3 and/or how to consolidate multiple files into one log file.

Which is slower single file or multi file?

Single file (database, log) databases are SLOWER than multi file – there are goo reasons to have X files each, with X being the number of cores. THis is all well documented by Microsoft – but it seems many people do not like reading (I rarely see a competent SQL admin in these and some other regards).

Why does my SQL Server transaction log keep growing?

Maybe not every 30 min like during the day, but an 11-hour window with no tran log backups is likely your issue here. Even if actual user activity is low, any other activity happening at night will grow the transaction log.

Why is my tlog file bigger than my VLF?

It states that if the DB is small and all the content of tlog file is in same VLF it couldn’t truncate. I have some 300-400 VLFs in the Databases. So that doesn’t make sense here as well. One thing I noticed that every morning at 6 AM the tlog is a little bigger than the other ones.

How big is the database transaction log file?

I have a database that was created with Full recovery model. Every night it performs backups of the database and the transaction log but inevitably the transaction log seems to continually grow over 2-3 weeks. When the remaining disk space gets to 1GB I will see that the transaction log is about 30GB.

What’s the maximum file size for DBCC shrinkfile?

DBCC SHRINKFILE won’t throw an error, and will quickly pass to the next line of code. However, if you underestimate the beginning maximum file size, mine is 90000, DBCC SHRINKFILE will have to work a lot harder to remove any margin in excess of 50 MB–for my example anyway.
