CA IDMS/DB Audit detects a number of different physical integrity errors. The first section of this chapter describes each type of error and provides an illustrated example. The conventions and the data structure diagram used for these examples are presented on the following pages.

QuickCheck and Standard are the two auditing methods CA IDMS/DB Audit provides. The method you select determines the types of errors CA IDMS/DB Audit can locate. The auditing method also greatly affects processing time.

In the audit phase, CA IDMS/DB Audit uses a variety of processes to find errors. This section of the chapter describes each process, the parameter used to initiate each process, and the specific error type it searches for. Set diagrams illustrate these processes.
