Using dumps in problem determination

Dumps are an important source of detailed information about problems. They give you a snapshot of what was happening in CICS® at the moment the dump is taken. CICS supports two different types of dumps; they are the CICS transaction dump, of transaction-related storage areas, and the CICS system dump, of the entire CICS region. The type of dump to use for problem determination depends on the nature of the problem. This section gives you guidance about using dumps to locate problems in your CICS system. However, you might need to use dumps with other sources of information relating to a longer period of time, such as logs, traces, and statistics.

IBM Support: SLIP dumps can be taken under guidance from IBM Support for specific problem determination purposes, particularly when the existing first-failure data capture (FFDC) cannot gather the level of detail required for specific problems. For detailed instructions, see Taking SLIP dumps.
