Assembly: libdb_dotnet52 (in libdb_dotnet52.dll) Version: 220.127.116.11
This setting implies the environment will only be accessed by a single process (although that process may be multithreaded). This flag has two effects on the Berkeley DB environment. First, all underlying data structures are allocated from per-process memory instead of from shared memory that is accessible to more than a single process. Second, mutexes are only configured to work between threads.
This setting should be false if more than a single process is accessing the environment because it is likely to cause database corruption and unpredictable behavior. For example, if both a server application and Berkeley DB utilities (for example, db_archive, db_checkpoint or db_stat) are expected to access the environment, this setting should be false.
