Laurels, Part 1

We’ve all heard it time and again. You know, how i5/OS security (and OS/400 before that) is better than all of the other widely used platforms or, better yet, how some folks consider this particular IBM operating system to be “bulletproof.” Of course, no system is completely secure, but those of you who have been around this system for any length of time know that i5/OS can most certainly provide a very secure environment for hosting and conducting critical business operations.

According to Jeff Uehling, the chief technical engineering manager for System i5 security, and Paul Godtland,

I have created an array to sort customer shipment data in the correct order for all part numbers that need to ship on a particular day. I want to define the array to grow as needed, as we anticipate our business growing. I don’t want the program blowing up when the number of elements is exceeded. Is it possible to dynamically size an array in an RPG program, rather than specify the number of elements at compile time?

I have two ideas for you, Jennifer. The first is to use RPG’s memory allocation features to get memory as you

Most i5 administrators know that system problems can occur when i5 disk units fill up. System degradation can occur when system storage reaches 90 percent, and the system can crash after storage usage passes 95 percent. But while disk drive capacity problems are fairly straightforward to handle, they are not the only storage problems that can occur on OS/400 boxes.

There is a second storage issue–identified when the system starts issuing CPI0999 error messages–that is not as clearly understood as traditional storage capacity problems. A CPI0999 issue can also create severe performance problems on your system and it should
