Managing journal resource definitions - IBM - AS/400

When a file is defined in the FCT, you can specify whether or not activity on that file is to be journaled and the ID of the journal file. Journal files are identified by a number in the range 1 through 99. In the journal control table (JCT), you define the characteristics of each journal file.
