Troubleshooting data for policy problems

CICS® MustGather for policy problems

Policy problems occur for different reasons. To identify the source of errors that affect policies:

After that, follow these guidelines to gather complementary diagnostic information before contacting the CICS support team.

Required data:
  1. Relevant messages from the CICS console log. These messages typically include any DFHMPnnnn message. For more information, see CICS messages.
  2. The CICS internal trace that is included in the MVS™ system dump when tracing is active. For more information, see Using trace for CICS problem determination on z/OS®. Ensure that the internal trace table size is big enough to contain sufficient data for diagnosis; for example, you can use a table size of 20480K. When possible, turn on level 2 tracing for the MP component and level 1 tracing for all other CICS components. If this is not possible, turn on level 1 tracing by following these rules:
    • For problems during the installation of a policy, turn on a minimum of level 1 tracing for MP, PI, SM, PG, and RL components.
    • For runtime problems, turn on a minimum of level 1 tracing for MP, EI, ME, and SM components. If the problem involves Time policies, also turn on level 1 tracing for the DS component. For policies with an action of event, also turn on level 1 tracing for EC, EP, and PG components.
  3. The MVS system dump that is taken when the problem occurs. The way that you get the dump depends on whether or not you get a message, transaction abend, or no output when the problem occurs. For more information, see Using dumps for CICS problem determination on z/OS.
  4. If you are unable to get a system dump, take a CICS auxiliary trace that leads up to the error. For more information, see Using trace for CICS problem determination on z/OS. If possible, turn on level 2 tracing for the MP components, and level 1 tracing for all other CICS components. If this is not possible, turn on level 1 tracing by using the following rules:
    • For problems during the install of a policy, turn on a minimum of level 1 tracing for MP, PI, SM, PG, and RL components.
    • For runtime problems, turn on a minimum of level 1 tracing for MP, EI, ME, and SM components. If the problem involves Time policies, also turn on level 1 tracing for the DS component. For policies with an action of event, also turn on EC, EP, and PG components.
