Rerun the deadlock victim sql server transaction.Deadlock occurs when two users have locks on separate objects and each user wants a lock on the other's object. When this sql error 1205 happens, SQL Server ends the deadlock by automatically choosing one and aborting the process, allowing the other process to continue. The aborted transaction is rolled back and an error message is sent to the user of the intra-query parallel deadlocks aborted process. Generally, the transaction that requires the least amount of overhead to rollback is the transaction that is aborted. Fix/Workaround/Solution: Deadlock priority can be set by user. In other words, user can choose which process should stop to allow other process to continue. SQL Server automatically chooses the process to terminate which is running completes the circular chain of locks. Sometime, it chooses the process which is running the for shorter period then other

process. To reduce the chance of a deadlock: Minimize the size of transaction and transaction times. Always access server objects in the same order each time in application. Avoid cursors, while loops, or process which requires user input while it is running. Reduce lock time in application. Use query hints to prevent locking if possible (NoLock, RowLock) Select deadlock victim by using SET DEADLOCK_PRIORITY.SQL SERVER 2005 has new priority HIGH as well as numeric-priority.SQL SERVER 2005 Syntax SET DEADLOCK_PRIORITY { LOW | NORMAL | HIGH |

Once you have the graph, you can post the information from it here, and we can better help you identify the specific cause of the deadlock, and offer ideas for how to resolve it. One thing to note is that if you catch the 1205 error, you can resubmit the batch/operation, and it will likely succeed since lock resources are often held only for a few microseconds.

Once it does, post the deadlock output from the error log. And perhaps post the job step's code.Depending on what the job does, I typically add retries to the job step. These days though, I am rewriting code that is run via SQL Agent and that is prone to deadlock by adding TRY/CATCH logic and looking for error 1205 (deadlock error). I then retry within the code so that I don't have to start all over again at the job step level. But it really depends on your situation. The type of job that I'm talking about here is a purge job (massive deletes in batches).Tara KizerMicrosoft MVP for Windows Server System - SQL Serverhttp://weblogs.sqlteam.com/tarad/Subscribe to my blog Topic Reply to Topic Printer Friendly Jump To: Select Forum General SQL Server Forums New to SQL Server Programming New t
