| We are using sql server 2005.I have been asked to investigate why a job that runs a particular stored procedure (SP) SOMETIMES hangs.What are the first steps to investigate this issue?Is this just a matter of going through the sql inside the SP and look for possible casue of locks among tables?...Any thoughts please?Thanks |

| First run thishttp://www.nigelrivett.net/SQLAdmin/sp_nrInfo.htmlThat may show the problem - if it is blocked by something it should be highlightedrunning DECLARE @sql_handle binary(20) SELECT @sql_handle = sql_handle FROM master.dbo.sysprocesses WHERE spid = @spid AND ecid = 0 SELECT * FROM ::fn_get_sql(@sql_handle)might show the statement causing problemsHave a look at thishttp://www.nigelrivett.net/SQLAdmin/SaveQueryPlans.htmlIt might show something.Running the profiler will show which statements are executed and show where it is stuck but will slow the system down a bit.This shows which locks are held - not sure if it works for v2005http://www.nigelrivett.net/SQLAdmin/sp_nrLocks.html==========================================Cursors are useful if you don't know sql.DTS can be used in a similar way.Beer is not cold and it isn't fizzy. |
