Incident logging function
In addition to determining the ending status of batch jobs by scanning SYSOUT data sets created by the job, the JCC has an incident-logging function. The JCC can be directed to record error conditions in an incident file. The incident file is a sequential file that is updated by a tracker exit, EQQUX006 (the incident-record-create exit). The incident-record-create exit is a required exit. You can use the standard exit that is shipped with the tracker or you can replace it with your own exit.
The incident log data set is never input to any tracker function. It is referenced only by the incident-record-create exit. It can, therefore, be shared by several JCC tasks running on the same or different systems. You can also update and even reallocate the data set manually while the JCC is active because the JCC reallocates the data set each time it is to be updated.
