Integrated file system

 

The integrated file system is a part of the i5/OS^® operating system that supports stream input/output and storage management similar to personal computer and UNIX^® operating systems, while providing you with an integrating structure over all information stored in the system.

• Overview of the integrated file system
  Here is some basic information about the integrated file system on your i5/OS operating system and how it can be of use on your system.

• Integrated file system concepts
  This topic introduces the basic concepts of integrated file system, such as directory, link, path name, stream file, name continuity, extended attributes, and scanning support.

• File systems
  A file system provides you with the support to access specific segments of storage that are organized as logical units. These logical units on your system are files, directories, libraries, and objects.

• Accessing the integrated file system
  All of the user interfaces, such as menus, commands, and displays, that are used to work with your system's libraries, objects, database files, folders, and documents still operate as they did before the introduction of the integrated file system.

• Converting directories from *TYPE1 to *TYPE2
  The "root" (/), QOpenSys, and user-defined file systems (UDFS) in the integrated file system support the *TYPE2 directory format as of OS/400^® V5R1.

• Journaling objects
  The primary purpose of journaling is to enable you to recover the changes to an object that have occurred since the object was last saved. Additionally, a key use of journaling is to assist in the replication of object changes to another system either for high availability or workload balancing.

• Reclaim operation of the "root" (/), QOpenSys, and user-defined file systems
  Reclaiming the "root" (/), QOpenSys, and user-defined file systems can be accomplished using the Reclaim Object Links (RCLLNK) and Reclaim Storage (RCLSTG) commands.

• Programming support
  To take advantage of the stream files, directories, and other support of the integrated file system, use a set of application programming interfaces (APIs) provided for accessing integrated file system functions.

• Working with files and folders using iSeries Navigator
  You can perform these tasks with files and folders.

• Transport-independent remote procedure call
  Developed by Sun Microsystems, remote procedure call (RPC) easily separates and distributes client applications from a server mechanism.
