When a user who is logged on to MSO exits from FOCUS or abends, all resources associated with the session are freed, including data areas, programs, control blocks, and data sets.
Information Builders Snapshot Facility is provided in case of an abend (see Common Installation Problems and Solutions). The facility supplements the standard OS/390 dump capabilities by producing a summary mini-dump whenever a task in the MSO address space abends. This snapshot aids in failure identification and diagnosis.
In addition, trace facilities, for example, FSTRACE, are provided by individual FOCUS components to assist in problem determination. These traces can be controlled from the OS/390 system console or from the MSO Console, as well as from individual FOCUS sessions.
