I received the SCOM alert that the Ultrasound Log file is running out of space. Further checking that the Ultrasound Log file is over 40GB while the Ultrasound Database file is only 15MB. I noticed that the Ultrasound Database is set to “Full” recovery model.

1. Should I perform a shrink file operation on the Ultrasound Log file ?
2. Should I change the recovery model to “Simple” ?

No answer as to how to reclaim space. I shrink after reindexing and have not found any issues at all. I don’t believe this post especially since there are no responses!

Hi Bourne,
run below script will give you free space detail for a database.

select
[FileSizeMB] =
convert(numeric(10,2),round(a.size/128.,2)),
[UsedSpaceMB] =
convert(numeric(10,2),round(fileproperty( a.name,’SpaceUsed’)/128.,2)) ,
[UnusedSpaceMB] =
convert(numeric(10,2),round((a.size-fileproperty( a.name,’SpaceUsed’))/128.,2)) ,
[DBFileName] = a.name

from
sysfiles a

i have questions:
1. how to find out the unused space in both database and log files prior to shrinking?
2. if it is bad then why microsoft provided the auto and manual shrinking options?

I see lots of people asking the same question that I have. “What do you do, if not shrink your databases, if you are out of hard drive space?”. Yet I really haven’t seen an answer from Pinal regarding this very question.
What do we do if the databases are so very large the only thing left to do is shrink them?

Hi all,

We have an application that access the sql db 24/7 – the dba’s are;
checking the db integrity
rebuilding indexes
update statistics
shrinking the database
This is being done weekly at a time where the application is still very active on the db – can this cause any corruption issues?

Shrinking a db that has grown to large for it’s disk may be necessary. defragging your indexes after shrinking is an option if you must shrink. Remember that it is very expensive for sql server to expand your data and log files when free space runs out. So if you shrink your data and your logs with dbcc shrinkdatabase command be sure to allocate a percentage of freespace to remain using the target-percent. How to determine the amount? Look at the growth of your log files over the past months and make a determination as to its future growth given what you find there. ou want to leave enough freeespace so it doesn’t expand for a year. You should do daily checks on your db so keep an eye on it’s growth after you have shrunk it. All in all shrinking should be done cautiously and only when absolutely needed. Never automatically or on a schedule!

[...] Earlier this year, I was working on SQL Server Performance Tuning consultancy; I had faced very interesting situation. No matter how much I attempt to reduce the fragmentation, I always end up with heavy fragmentation on the server. After careful research, I figured out that one of the jobs was continuously Shrinking the Database – which is a very bad practice. I have blogged about my experience over here SQL SERVER – SHRINKDATABASE For Every Database in the SQL Server. [...]

Thanks Pinal and others for this discussion I want to know do we have any alternative to meet both the needs
1)Eliminate unused space in DB (since sometimes this space becomes huge)
2)Avoid Index Fragmentation (Rebuilding the indexes)

What should be efficient step to achieve these goals?

Regards,
Nishit
