Kill SQL Server Process Ids (spids)
I have noticed some of my processes are failing because spids are already connected to the database. This happens specifically when I need to a restore database. I catch this problem pretty quick when I am working on it during the data and can fix it, but during nightly processing existing spids become problematic. I have also noticed existing spids causing problems for my SQL Server 2000 Database Maintenance Plans. I have found this issue in my logs specifically related to performing integrity checks (DBCC CHECKDB ('YourDatabaseName') REPAIR_FAST) when the database needs to be in single user mode before the integrity check commands run. How can I kill these spids prior to running my processes?
Killing the spids is the process that needs to occur prior to issuing DBCC CHECKDB (when repairing) or performing the database restore process. Killing the spids can be accomplished by adding another step to your SQL Server Agent Jobs or in your script\stored procedure calling the code below to perform the KILL process prior to executing code that needs exclusive use of the database.
SQL Server 2000 and SQL Server 2005
- Check your Database Maintenance Plan logs or SQL Server Agent Job Step History to determine when existing spids are preventing your automated processes from succeeding.
- Depending on the user and/or automated processes that are running dictates how the scripts above should be modified to meet your needs.
- Although the scripts above are beneficial for you to execute your process, you may also need to consider the other processes that are running and determine if 1 or more of the processes need to be executed at another time period for all of the processes to complete in a reasonable time period. For example, you may not want to kill a process at 4:00 AM that needs 4 hours to complete and must be finished by 8:00 AM. In this circumstance, re-scheduling the process may be a better bet.
