InitRegions Field

BerkeleyDB

If true, Berkeley DB will page-fault shared regions into memory when initially creating or joining a Berkeley DB environment. In addition, Berkeley DB will write the shared regions when creating an environment, forcing the underlying virtual memory and filesystems to instantiate both the necessary memory and the necessary disk space. This can also avoid out-of-disk space failures later on.

Namespace:  BerkeleyDB
Assembly:  libdb_dotnet48 (in libdb_dotnet48.dll) Version: 4.8.24.0

Syntax

C#
public bool InitRegions
Visual Basic (Declaration)
Public InitRegions As Boolean
Visual C++
public:
bool InitRegions

Remarks

In some applications, the expense of page-faulting the underlying shared memory regions can affect performance. (For example, if the page-fault occurs while holding a lock, other lock requests can convoy, and overall throughput may decrease.)
