Have you ever wondered what Iused and %Iused mean in UNIX commands like df or what people are talking about when the say inode? UNIX and Linux systems both use inodes, and IBM AIX is no different. Discover what an inode is and why inodes are important to UNIX, the structure of an inode, and commands for working with inodes.

Use IBM Informix Dynamic Server Developer Edition for applications development and prototyping. Developer Edition is available free of charge, for development use only, with no time limits, and no support.

Threaded programming in Python can be done with a minimal amount of complexity by combining threads with Queues. This article explores using threads and queues together to create simple yet effective patterns for solving problems that require concurrency.

HACMP/XD uses PPRC mirroring technology to provide disaster recovery for critical applications' data. This involves collecting configuration data from the storage as well as from the cluster nodes; at times this can be tedious. This article shows you how, using pprc4hacmp, configuration data is generated automatically for HACMP/XD-PPRC.

Learn to make use of the Kerberos authentication tickets in the day-to-day network services on IBM AIX V6 and discover how Kerberos can be useful in getting rid of the password hassles for network service logons. This is another method towards achieving single sign on (SSO) on an AIX system network.
