Many systems programmers spend hours debugging problems that involve looping or hung transactions. By working together, z/OS and CICS systems programmers resolve these problems much faster by combining the information available from OMEGAMON XE on z/OS and OMEGAMON XE for CICS on z/OS.
A typical scenario is that the z/OS systems programmer identifies an address space with a high (or low) CPU Percent. Most often, this is in response to a situation alert or a reported problem. Starting with the Address Space Overview workspace in OMEGAMON... [More]
