Global DSM consists of a centralized administrative program that executes in its own address space and communicates with sorts in progress through the z/OS subsystem interface.
All messages issued by global DSM are routed to the console and have the form:
WERxxxy message text
xxx is the message number and the y is either the letter A or the letter I.
The messages with A indicate a critical error. These messages are routed to the console with ROUTCDE=(2,11) and DESC=(2).
The messages with I provide information on global DSM execution or a condition not severe enough to warrant global DSM termination. These messages are routed to the console with ROUTCDE=(2,11) and DESC=(4).
