Hello experts,
Message
Executed as user: NT AUTHORITY\SYSTEM. The transaction log for database 'tempdb' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases [SQLSTATE 42000] (Error 9002). The step failed.
in my sql server agent job i have the above error, this type of errors i got some of multiple jobs. anyone kindly give permanent solutions.
Thanks in advance ....

Increase space in TempDB, set it to autogrow, manually increase the file size, increase space on the TempDB drive if its at capacity.

you'll need to try and increase the t-log space for tempdb. If you try to use the GUI this will likely fail so try the following (replace ? with the number of MBs you wish the new maxsize to be)

ALTER DATABASE [tempdb] MODIFY FILE (name=templog, maxsize = ?MB)

Thank you for yours respond , but my tempdb data file is already unrestricted growth only

The error is related to the transaction log file.

Is that unrestricted also? If so you may be hitting the disk capacity and need a bigger disk.

then you are out of disk space on the drive? you might need to add additional files, on other drives, to allow it to have more space.

if it's a drive on a SAN share, you might need to ask your network guys to allocate more space.

if it got this big once, it will continue to do so, as you've got processes that need a lot of temp space.

Thank you for yours response

In Temdb database properties there are 4 data files and 2 log files which is unrestricted growth, and disk space is assigned to D: drive which is still i have 50GB free space ..

2 log files? How come?

Only 1 log file will be used until it becomes full then the other one will take over as logs a sequential so no need to have more than 1 in a normal operational DB.

OK its unrestricted growth but what is the growth increment? If its a percentage, whats the size of the current file?

What else is on D?

Perry Whittle SSC Guru Points: 234013 More actions · Answer 8

the t-log file is the problem, the error clearly states this!

Please post results of the following;

PowerShell query

Get-Volume | ?{$_.drivetype -EQ "Fixed"} | ft DriveLetter,FileSystemLabel,HealthStatus,SizeRemaining,Size

TSQL query

SELECTname

, size / 128 AS SizeMBs

, max_size / 128 AS MaxSize

, case is_percent_growth

WHEN 0 THEN CAST(growth / 128 AS VARCHAR(20)) + 'MBs'

ELSE CAST(growth AS VARCHAR(20)) + '%'

END AS Growth

FROM sys.master_files

WHERE database_id = DB_ID('tempdb')
