Using CICS TS autojournaling

CICS® TS supports the automatic journaling (autojournaling) of file control data to a specified general log stream. Parameters specified in the CICS definitions of VSAM files determine whether or not autojournaling is to be performed, and the types of operations (add, read, or others) that are recorded.

IBM® recommends that the log records produced by CICS TS autojournaling must only be used for audit purposes, for the following reasons:
Despite the known risks, some users want to use log records produced by CICS TS autojournaling to forward recover VSAM spheres, because this process has the following advantages over forward recovery logging:
With the possible limitations noted above, CICS VR can forward recover a VSAM sphere from log records produced by CICS TS autojournaling. However, note again that IBM recommends using log records produced by CICS forward recovery logging to recover VSAM spheres. Also, please note the following restrictions when log records produced by CICS TS autojournaling are used for the forward recovery of VSAM spheres:

The following sections explain the steps required to enable CICS TS autojournaling for VSAM spheres and to set up CICS VR to forward recover the spheres from the autojournal log records.
