Troubleshooting intermitten connectivity issues can be difficult. One approach is to repeatedly test connecting to SQL Server outside of an existing application in order to verify if a server-wide intermitten issue is occurring.

This is a replacement for SP_who and modification of sp_who2. It will always list only active, nonsystem processes, and will list the number of seconds a transaction has been running for. Some transactions do not report a last batch time, so I forced a large value to display so you can see any issue with […]

Examining the output of DBCC SQLPERF(UMSSTATS) helps in determining a CPU bottleneck. The output of the command is not handy for further investigation (from a table).This procedure performs a transformation of the results, so it is easy to query and store in a database.

sp_who (and sp_who2) work great for a quick view of what's going on in the system, and can be filtered by user, but there's no way to filter by database. This quick stored procedure provides data on which users are accessing a specific database.

This script identifies the blocking locks at the top of the blocking chain and kills them. Specifically, it reports what the top blocking spids are doing, kills them, waits three seconds and then reports on current blocking status. If you have a situation where single connections are causing a huge blocking chain and you want […]
