Integrated File System Introduction
Considerations for moving objects to another file system
Each file system has its own unique characteristics. However, moving objects to a different file system may mean losing the advantages of the file system in which the objects are currently stored. You may want to move objects from one file system to another to take advantage of those characteristics. Before moving objects to another file system, you should be familiar with the file systems on the integrated file system and their characteristics. For more information, see File systems in the integrated file system.
You should also consider the following:
- Are you using applications that use advantages of the file system that the objects are currently in?
Some file systems support interfaces that are not part of the integrated file system support. Applications that use these interfaces may no longer be able to access objects that are moved to another file system. For example, the QDLS and QOPT file systems support the hierarchical file system (HFS). APIs and commands work with document and folder objects. You cannot use these interfaces on objects that are in other file systems.
- What characteristics of the objects are important to you?
Not all characteristics are supported by all file systems. For example, the QSYS.LIB or Independent ASP QSYS.LIB file systems support storing and retrieving only a few extended attributes, whereas the "root" (/) and QOpenSys file systems support storing and retrieving all extended attributes. Therefore QSYS.LIB and Independent ASP QSYS.LIB are not good candidates for storing objects that have extended attributes. QDLS supports many "office" attributes, but other file systems do not. Therefore, QDLS is a good place to keep your office documents.
Good candidates for moving are the PC files that are in stored in QDLS. Most PC applications should be able to continue working with PC files that are moved from QDLS to other file systems. The "root" (/), QOpenSys, QNetWare, and QNTC file systems are good choices for storing these PC files. Because they support many of the OS/2 file system characteristics, these file systems can provide faster access to files.
