Analyzing for resource contention

You can obtain information related to resource contention by using the IPCS subcommand ANALYZE. This subcommand displays contention information for I/O, ENQs, suspend locks, allocatable devices and real storage. For example, in Figure 1, 61 units of work are waiting to be processed. The top RB is in a wait state.
