Solution ID: 13284
GOAL:
What are AS/400 PTFs?
FACT(s) (Environment):
Progress/400 DataServer
FIX:
PTF stands for "program temporary fix" and is analagous to a progress patch.
IBM distributes PFTs to either fix defective code or to add functionality to existing code. PTF's may be distributed individually or in groups called cumulative PTF packages.
PTF's may be for microcode (machine code), the operating system, or an IBM licensed program product. Microcode and operating system PTF's cannot be applied when the machine is in use. They must be loaded onto the machine and marked for as "delayed" apply which means that the PTF will be applied the next time the AS/400 goes through an IPL (initial program load).
There are several steps required to make a PTF part of the AS/400 code.
1. It must first be "loaded" or transferred from tape media to the machine.
2. The second step is to "apply" the PTF to the code. The application of a PTF will differ depending on the type of PTF it is.
