Format of a journal record

Each general log comprises a stream of contiguous blocks of journaled data. Each block comprises a journal control label header followed by a variable number of CICS journal records. Each CICS journal record comprises a system header, system prefix, user prefix, and journaled data.

A graphical overview of the format of a general log, showing the format of a complete block, is shown in Figure 1.
