Examples
Locking
This section describes choices you need to make when deciding on how to use EclipseLink locking options in your application architecture. We strongly recommend always using a locking policy in a concurrent system (see Configuring Locking Policy).
These choices can be summarized as follows:
- Optimistic Locking
- Pessimistic Locking
If you are building a three-tier application, be aware of how that architecture affects the way you use locking (see Locking in a Three-Tier Application).
For more information, see Descriptors and Locking.
