If true, Berkeley DB will flush database writes to the backing disk before returning from the write system call, rather than flushing database writes explicitly in a separate system call, as necessary.

Namespace: BerkeleyDB
Assembly: libdb_dotnet60 (in libdb_dotnet60.dll) Version: 6.0.35.0

# Syntax

C#
    public bool ForceFlush

Visual Basic (Declaration)
    Public ForceFlush As Boolean

Visual C++
    public:
    bool ForceFlush

# Remarks

This is only available on some systems (for example, systems supporting the IEEE/ANSI Std 1003.1 (POSIX) standard O_DSYNC flag, or systems supporting the Windows FILE_FLAG_WRITE_THROUGH flag). This flag may result in inaccurate file modification times and other file-level information for Berkeley DB database files. This flag will almost certainly result in a performance decrease on most systems. This flag is only applicable to certain filesysystems (for example, the Veritas VxFS filesystem), where the filesystem's support for trickling writes back to stable storage behaves badly (or more likely, has been misconfigured).
