You've been working with Solaris for ten years now and, like many other companies, you have just started a large server consolidation and migration project to AIX® 6.1 from Solaris 10. Many of the commands are similar, but you need to know how to work with partitioning and virtualization. What are the partitioning differences between an IBM® and Sun server? Furthermore, what do you need to know about workload partitions (WPARs) to make a successful transition from containers? What are some of the similarities and differences between WPARs and zones, and how does the process differ from creating zones and WPARs? Finally, what can you do on the IBM System p™ that you can't do with Sun servers? These are some of the questions addressed in this article, with the objective of making your transition easier.
Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned. The only real rules are that "/" is always the directory separator, and that filenames can't contain byte 0 (because this is the terminator). Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....
