311:), approximately on a monthly basis. They can now be downloaded straight to the system through a direct connection to IBM support. In some instances IBM will release a "Cumulative PTF Pack", a large number of fixes which function best as a whole, and are sometimes codependent. When this happens, IBM issues compact discs containing the entire PTF pack, which can be loaded directly onto the system from its media drive.

These repairs to IBM software are often in response to APARs submitted by customers and others and acted on by IBM, and are a common first step to resolving software errors. It is generally expected by the customer that the problem would be fully corrected in the next release (version) of the
337:. In rare cases an installation may install a single PTF, but normally it will install all available service except PTFs excluded by, e.g., aging policies, HOLDDATA. Details vary from installation to installation, but a simple service cycle would involve these steps:
501:
The focus of the "APAR fix" is "to rectify the problem as soon as possible" whereas the PTF "is a tested APAR... The PTF 'closes' the APAR. " Prior to that, an APAR is "a problem with an IBM program that is formally tracked until a solution is provided.”
50:), and where an "APAR fix" was issued, the PTF "is a tested APAR" or set of APAR fixes. However, if an APAR is resolved as "Fixed If Next" or "Permanent Restriction" then there may be no PTF fixing it, only a subsequent release.
518:, because they have the option to make the PTF a permanent part of the operating system if the patch fixes the problem. One explanation of Program Temporary Fix says it's temporary, just until the next ice age.

IBM support staff, if they suspect that a defect in a current release of an IBM program is the cause, will file a formal report confirming the existence of an issue. This is referred to as an
