  • Large log file CommServe DB
    Posted: 01-26-2015, 12:17 PM

    On my commserve box, we are using sql mirroring to copy the DBs to a standby commserve.

    we are using version 10 r2 sp9

    When i set up the mirroring, i tried to make a backup of the db and log using sql mgmt and it failed.

    it turns out that the cx_log1.ldf is very large; at about 103GB.  The log files is about the same size on the standby commserve.


    is there a way to shrink this log properly so that i can gain some free space back on my primary and standby box?

    I would recommend opening a case with the Support Hotline.

    They will have to investigate further and probably run a SQL command to shrink the logs.  Once that is done, the next step may be to run a Full backup with the SQL iDA and schedule this for once a week followed by running Transaction log backups which should then keep the logs from growing.

    i worked with the DBA here and we tried some things. i uses the SQL iDA to make a full backup. this did nto solve the issue, so i tried a SQL transaction backup. I then ran a shrink command. the file is still 50GB, but the used space is at 600MB.  although not ideal, i will take any amout of shrink for now.

    i will keep you posted if i find a way to shrink the rest of the file.

    using sql mgmt:

    i used the following sql query to see the size.

    ;with space_used_cte as




            size * 8.0 / 1024 as size_mb,

            fileproperty(name, 'SpaceUsed') * 8.0 / 1024 as space_used_mb

        from sys.database_files






        convert(decimal(5, 2), space_used_mb / size_mb * 100) as space_used_percent

    from space_used_cte;


    I used the following query to shrink the DB

    dbcc shrinkfile(YourDatabaseFileName, <target size in MB>);

    Hi Ian, hope you are well.

    If possible would suggest to call in to log an incident, this may not be expected and may becoming progressively worse.  Support will need a copy of the CommServe DB and CommServe log files as well, also if you have the SQL trace files, there is a check box in the GUI when you send logs to include SQL logs as well.

    Have you tried the DBMaintenance Utility?

    and is say that sparingly, the logs should self-maintain the size/cleanup routines, there shouldn't be a constant need for manually intervening and manipulating it outside of conventional methods.  Would strongly suggest not to venture into this realm too deeply to resolve it, and best approach I feel is to have it reviewed via the Support team with a copy of the latest CommServe DB backup, and CS log, along with SQL server logs if you can grab them.
