As you consider making index changes to a large, busy table, you need to consider your workload characteristics. You should be more reluctant to add additional indexes if you have an OLTP workload. You should take advantage of online index operations whenever possible if you re running Enterprise Edition in order to avoid locking and blocking issues during index builds. You also should consider using the MAXDOP option during index builds to prevent SQL Server from using all of the CPU cores for an index build. This may mean that the index takes longer to build, but the rest of your workload won t be starved for CPU during the index-creation process.

Especially with OLTP workloads, you may run into blocking issues with SQL Server. Listing 24 shows one quick DMV query that s a good, indirect early warning signal of blocking.

Of course, the robot must be able to survive conditions at its location Also, it must have some way to recover if it falls or gets knocked over

If you see the current_tasks_count above 10 for a sustained period, it s likely that you have blocking. When you have severe blocking, the current_tasks_count for each scheduler tends to go up quickly. The two DMV queries in listings 25 and 26 will give you more direct confirmation of blocking.
