Independent ASP QSYS.LIB

 

The independent ASP QSYS.LIB file system supports the i5/OS^® 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 i5/OS object types that the library support manages in the independent ASPs.

In addition, it:

• Supports all user interfaces and programming interfaces that operate on i5/OS 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 i5/OS objects

• Supports stream I/O operations on physical file members, user spaces, and save files
