Long simultaneous transactions which variously lock and unlock resources must be carefully designed to avoid deadlocks. Lock-Avoiding Design Strategies There are a few design strategies that can reduce the occurrence ...
Blocking is an unavoidable and by-design characteristic of any relational database management system (RDBMS) with lock-based concurrency. As mentioned previously, in SQL Server, blocking occurs when one session holds a lock on a specific resource and a second SPID attempts to acquire a conflicting...
