Nothing else reduces the size of the physical file.Since the log file is 99% free space, log reuse is working properly and there's no problems here, nothing to be concerned about.Tue, 11 Dec 2012 23:41:45 GMTGilaMonsterhttp://www.sqlservercentral.com/Forums/Topic1395407-391-1.aspx[quote][b]Mohammed Imran Ali (12/11/2012)[/b][hr]The transaction log file does not go down even after database full backup is completed[/quote]Full database backup will not reduce Tlog size.Have you verified the status of VLF's?

I am not able to find any open transactions or orphaned transactions. The transaction log file does not go down even after database full backup is completed. The database has 2 data files and 1 log file. sp_helpfile for the database shows the below resultsname fileid filename filegroup size maxsize growth usageDB1_Data 1 x:\Data\DB1_Data.MDF PRIMARY 39000960 Unlimited 10% data onlyDB1_Log 2 x:\Data\DB1Lob_Data.MDF NULL 30864960 2147483648 10% log onlyDB1Lob_Data 3 y:\Log\DB1_Log.LDF PRIMARY_LOBS 1437888 Unlimited 10% data onlyThe DB1_Log (Tlog file) has the data file mapped to it and the DB1Lob_Data (Secondary Data file) has the log file mapped to it. Could this be the reason why the log file is not releasing space? Any clarification on this is much appreciated.Tue, 11 Dec 2012 20:38:46 GMTMohammed Imran Ali
