Issue/Introduction

When database records are compressed (either with IDMSCOMP/DCOM or with PressPack), only the compressed images are written to the journals.

It can be useful to view the uncompressed version of such data.

Environment

Release : All supported releases.

Component : IDMS

Resolution

The Journal Analyzer component product can be used to view journal images compressed with either IDMSCOMP/DCOM or PressPack.

Note that Journal Analyzer is now freely available under Portfolio Simplification.

Alternatively, for PressPack compressed images, user program calls to IDMSUNPS can be used a documented here:- https://techdocs.broadcom.com/us/en/ca-mainframe-software/database-management/ca-idms/19-0/administrating/using-presspack/creating-dcts-with-idmspass/create-dcts.html
