Dealing with exception conditions

Several tools and techniques are available for dealing with error conditions in a CICSPlex® SM API program.

Default CICSPlex SM exception handling
The CICSPlex SM API writes an exception trace, in the form of a user trace record, to the CICS® trace data set.
Using the RESPONSE and REASON options
The RESPONSE and REASON options are required on each API command.
Retrieving FEEDBACK records
In addition to the specific values returned by a command's RESPONSE and REASON options, CICSPlex SM also provides diagnostic data in the form of FEEDBACK resource table records. This data can help you evaluate the results of an API command, especially if the command did not complete successfully.
Retrieving MASQRYER records
When a command directed at CICS operate resources fails to complete because one or more target systems do not respond in a timely manner, CICSPlex SM provides more diagnostic data in the form of MASQRYER resource table records. This data can help you identify MASs or CMASs that failed to respond, and the reason for the failure.
