Hi friends,

We need to monitor a user session for locks to troubleshoot a problem in the program. When the program is started we would like to schedule a job to check for the locks every 5 minutes and the output should be saved into a new text file for each run.. I use sql query to check the locks and I run this as T-SQL script in a scheduled job but every time the job runs output file is being overwritten.. not sure how to output the results into a new seperate text file when the job runs every 5 minutes...

Any help is greatly appreciated... Thanks a lot for all your help

Below is the sql query I'm using to check the locks as a scheduled job to run every 5 minutes.. But I would need to create a new seperate output file for every run every 5 minutes..
BCP errors that the query is too long

SELECT
	spid = Lock.request_session_id,
	HostName = Session.host_name,
	ProgramName = Session.program_name,
	Cmd = Request.Command,
	LoginName = Session.login_name,
	dbid = Lock.resource_database_id,
	DatabaseName = DB_NAME(Lock.resource_database_id),
	Type = Lock.resource_type,
	LockType = Lock.request_type,
	Mode = Lock.request_mode,
	Status = request_status,
	UserTable.Name
	
FROM
	sys.dm_tran_locks AS Lock

	LEFT JOIN
	sys.dm_exec_sessions AS Session ON
		Session.session_id = Lock.request_session_id

	LEFT JOIN
	sys.dm_exec_requests AS Request ON
		Request.session_id = Session.session_id

	LEFT JOIN
	sys.tables AS UserTable ON
		UserTable.object_id = Lock.resource_associated_entity_id
		AND
		type = 'U'

WHERE
	Lock.resource_type = 'OBJECT'
go

Please help.. thanks a lot

Under the advanced tab for the job step where you specified the output file, there is a checkbox for "Append output to existing file". Without this box checked the output file will be overwritten each time.

Hi Jeremy,

I do not want to append it the existing file either.. We would want a new seperate file created when the job runs every 5 minutes... not sure if it can be done may be with a time stamp included in the file name or if there is any other way to do this.. Also is it possible to output the result in a xls/csv format? Please help thanks again

You can use Agent Tokens in your log name.

Using Tokens in Job Steps- SQL Server 2008 R2

Change the log name to something like this:

X:\...path to log files...\filename_$(ESCAPE_NONE(STRTDT))_$(ESCAPE_NONE(STRTTM)).log

And you'll get a file name like this on each run:

filename_20130305_231247.log

You can in 2008 and up, and maybe in later service packs of 2005, but in any case you may not want to do that. In 2005, and in some scenarios still in 2008 and up, queries issued by SQL Agent against msdb bloat the cache significantly. The more often you run jobs, the worse the problem becomes.

http://connect.microsoft.com/SQLServer/feedback/details/526485/dm-exec-cached-plans-bloat

Instead of only scheduling the job to run every 20 seconds, maybe it would be better to have the proc that does the checking use WAITFOR DELAY inside a loop to check the condition every 20 seconds allowing the job to run continuously. The proc would only take action when the condition was detected and would always loop back to the WAITFOR DELAY.

Hi friends,

We have a scheduled job set to run every 4 seconds from the time the job is enabled. The below sql in the job runs and appends the results every 4 seconds in the output file. Once the program ends we disable the job.

Would like to know if this can be done in a stored procedure so that it can be called from the program itself and it can be easier to track down when the error occurs.. Please give me your suggestions


SELECT
	spid = Lock.request_session_id,
	HostName = Session.host_name,
	ProgramName = Session.program_name,
	Cmd = Request.Command,
	LoginName = Session.login_name,
	dbid = Lock.resource_database_id,
	DatabaseName = DB_NAME(Lock.resource_database_id),
	Type = Lock.resource_type,
	LockType = Lock.request_type,
	Mode = Lock.request_mode,
	Status = request_status,
	UserTable.Name
	
FROM
	sys.dm_tran_locks AS Lock

	LEFT JOIN
	sys.dm_exec_sessions AS Session ON
		Session.session_id = Lock.request_session_id

	LEFT JOIN
	sys.dm_exec_requests AS Request ON
		Request.session_id = Session.session_id

	LEFT JOIN
	sys.tables AS UserTable ON
		UserTable.object_id = Lock.resource_associated_entity_id
		AND
		type = 'U'

WHERE
	Lock.resource_type = 'OBJECT'
go

Thanks a lot
