program temporary fix (PTF)
In IBM, a program temporary fix (PTF) is a temporary solution to a bug
in an IBM software product that is made available for customers to install. A PTF is developed
after a customer or someone at IBM encounters the problem and an authorized program analyis report
(APAR) is
written. The PTF effectively "closes" the APAR and then is made available for delivery to
customers. PTFs can be applied individually but are usually made available as part of a fix package
that includes a number of PTFs. A fix package can be distributed as one or more downloadable
compressed files or on a CD-ROM.
Meanwhile, the PTFs are provided to the development group that is working on the next product
release. The developers may or may not use the PTFs (since these are temporary fixes), but will
determine and design the correct problem solution to incorporate in the next product release.
