Authorized Program Analysis ReportAn APAR (Authorized Program Analysis Report)[1] (pronounced A-PAR, rhymes with far) is an IBM designation of a document intended to identify situations that could result in potential problems. It also serves as a request for the correction of a defect in current releases of IBM-supplied programs. The Process"Occasionally"[2] IBM software has a bug. Once it has been ascertained that the situation has not been caused by problems in third-party hardware or software or the user's configuration errors, 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. In addition to confirming the existence of an issue, APARs include information on known workarounds, information on whether a formal fix is scheduled to be included in future releases, and whether or not a Program Temporary Fix (PTF) is planned.[2] Documenting the problemIBM has a program to facilitate documenting the problem.[3][4] Solution levelsThere are at least 2 levels of fix:[5]
A PTF is a permanent correction with respect to the VRM (Version, Release, Modification) level of the product to which it is applicable, and is a temporary fix in the sense that the problem correction will temporarily be available as a permanent fix, and later will be incorporated into the product base code, and will thereby no longer be a fix, although the associated PTF and/or APAR numbers will, as a rule, be included in the source documentation associated with the ensuing base code update. System Improvement/Difficulty ReportSIDR was Xerox's acronym, covering APAR and PTF. The acronym referred to: System Improvement / Difficulty Report.[9] System Improvement RequestSIR (System Improvement Request) is a terminology that Digital Equipment Corporation used, much as Xerox used SIDR.[10] See alsoReferences
