Using the Deadlock report - Documentation for BMC AMI Log Analyzer for IMS 1.7

The Deadlock report provides information about record lockout situations, also known as a deadly embrace between two or more transactions.

In this situation, a transaction locks record A and attempts to lock record B. However, a second transaction has already locked record B and is attempting to lock record A. Because neither transaction can continue until the other transaction releases its locks, IMS typically issues a user 777 or 123 pseudo abend for one of the transactions.
