Once a CA product is installed at your site, you must apply maintenance from time to time. Maintenance usually consists of fixes to the software, updates to the documentation, and updated tapes. Maintenance is supplied in the following ways:
Because maintenance is packaged in SMP/E format, you can install your CA product installation and maintenance tapes using SMP/E.
Program fixes are provided in response to errors in the code of a product. Fixes are usually in the form of a zap, module replacement, or source update. CA supplies fixes as either an APAR (authorized program analysis report) or a PTF (program temporary fix). An APAR is an official, tested fix to a software problem. A PTF can be a Test PTF, a Special PTF, or an Official PTF. A Test PTF is a test version of a fix; a Special PTF modifies a documented function of a product; and an Official PTF is a tested, official module intended to fix one or more problems, always in the form of a source or module replacement.
