AFCN
Explanation
The transaction issued a file request that caused file control to attempt to create a journal record but the record was too large for the journal buffer to accommodate. This indicates that a journal referenced in the file definition is using an MVS logstream, which in turn, is using a coupling facility structure which has been defined with a MAXBUFSIZE parameter less than the recommended 64000.
System action
The task is abnormally terminated with a CICS transaction dump.
User response
Redefine the coupling facility structure that the logstream is using with a MAXBUFSIZE parameter of 64000. The journal in error can be the forward recovery log or the journal used for auto-archiving. If the module that detected the error is DFHDMPCA, the error is associated with a journal referenced in the definition of the CSD (DFHCSD).
