Open systems file system (QOpenSys)
The QOpenSys file system is compatible with open system standards based on UNIX, such as POSIX and X/Open Portability Guide (XPG). Like the "root" (/) file system, this file system takes advantage of the stream file and directory support that is provided by the integrated file system.
In addition, it:
- Is accessed through a hierarchical directory structure similar to UNIX systems.
- Is optimized for stream file input and output.
- Supports multiple hard links and symbolic links.
- Supports case-sensitive names.
- Supports local sockets.
- Supports threadsafe APIs.
- Supports *FIFO objects.
- Supports the journaling of object changes.
- Supports the scanning of objects using the integrated file system scan-related exit points.
The QOpenSys file system has the same characteristics as the root
(/) file system, except it is case sensitive to enable support for UNIX-based open systems standards.
Accessing QOpenSys
QOpenSys can be accessed through the integrated file system interface using either the IBM i file server or the integrated file system commands, user displays, and APIs.
