JOURNALING IN AS400 PDF

Changes in new members added to the file are also journaled. The user can specify that only the after image or both the before and after images of records in the journaled physical file be journaled. In addition, the system will automatically capture the before images for a database file if the file is opened under commitment control. The file must be saved because journaled changes cannot be applied to a version of the file that was saved before journaling was in effect. Even if the distribution request fails, the local file remains journaled.
