APARs - Multiple APARs

Enhanced Definition

An **APAR** (Authorized Program Analysis Report) is a formal report submitted to IBM by a customer detailing a suspected defect or problem in an IBM software product (e.g., z/OS, CICS, DB2). The concept of "Multiple APARs" often refers to a collection of these problem reports and their associated fixes (PTFs) that are applied together, either due to interdependencies, as part of a scheduled maintenance bundle, or to address a complex issue affecting several components.

Key Characteristics

- Unique Identification: Each APAR is assigned a unique identifier (e.g., PQ12345) by IBM, which tracks the reported problem and its resolution status.
- Problem Description: An APAR includes a detailed description of the problem, symptoms, and conditions under which it occurs, aiding IBM in diagnosis and resolution.
- Resolution via PTF: Successful APARs result in a PTF (Program Temporary Fix), which is the actual code change or modification provided by IBM to correct the reported defect.
- Interdependencies: Multiple APARs often have complex prerequisite or co-requisite relationships, meaning one APAR's PTF might require another APAR's PTF to be applied first or concurrently.
- Bundling for Maintenance: IBM frequently bundles multiple APARs/PTFs into larger maintenance packages, such as **
