Hi All,

While running one sp am getting this below error

'The transaction log for database 'testdb' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases'

i tried to dbshrink using dbcc command still no use . i'll get small space but i.e not sufficient for my query or sp so i'll get the same error again.

so i wanted to clear log file completely or i wanted to move it to any other path .

Please provide quick solution for my problem.

Thanks,
Ravi@sql

What is the recovery Model of the database?
What is the size of t-log and growth options?

Sounds like you need to do some transaction log management.

What is the output of this query

select recovery_model_desc, log_reuse_wait_desc from sys.databases where name = 'testdb'

if your database is using the full or bulk logged recovery model take a transaction log backup using the following

BACKUP LOG [MYDB] TO DISK = 'some drive\some path\mydb.trn'

recovery_model_desc log_reuse_wait_desc
SIMPLE NOTHING

What size is the transaction log?
Does it have any growth configured?

Space in t-log is made reusable in SIMPLE recovery model as soon as the transaction is Committed/ written to the database. Have you restricted your t-log growth? If you don't have enough space in the drive hosting t-logs consider using smaller transactions and frequent COMMITs.

You can try the below options:

Increase the size of 'MAX GROWTH' (If ample space is available in the drive hosting t-log)

If not, you can try this

USE MASTER
GO
DBCC FREESESSIONCACHE WITH NO_INFOMSGS
GO
DBCC FREESYSTEMCACHE 'ALL'
GO
USE (YOURDBNAME)
GO
DBCC SHRINKFILE (N'LOGFILENAME', 0, TRUNCATEONLY)
GO
DBCC SHRINKFILE (N'LOGFILENAME' , 1024)
GO
