Independent ASP QSYS.LIB

The independent ASP QSYS.LIB file system supports the iSeries™ server library structure in independent auxiliary storage pools (ASPs) you create and define. This file system provides access to database files and all of the other iSeries server object types that the library support manages in the independent ASPs.

In addition, it:

Supports all user interfaces and programming interfaces that operate on iSeries server libraries and objects in those libraries in independent ASPs
Supports all programming languages and facilities that operate on database files
Provides extensive administrative support for managing iSeries server objects
Supports stream I/O operations on physical file members, user spaces, and save files

Use independent ASP QSYS.LIB through the integrated file system interface

The independent ASP QSYS.LIB file system can be accessed through the integrated file system interface using either the i5/OS™ file server or the integrated file system commands, user displays, and APIs.

In using the integrated file system interfaces, you should be aware of the following considerations and limitations.

In general, the independent ASP QSYS.LIB file system does not distinguish between uppercase and lowercase in the names of objects.
Path names in the independent ASP QSYS.LIB file system
Each component of the path name must contain the object name followed by the object type of the object.
Links in the independent ASP QSYS.LIB file system
Symbolic links cannot be created or stored in the Independent ASP QSYS.LIB file system.
