  • Mainframe-Tools


    Moving or taking-over a complete batch production or parts if it to another system environment or data center is a real challenge! To avoid any problems caused by e.g. missing objects, wrong naming conventions, non-existing environments etc. we develop the Batch-Replicator!


    The Batch Replicator allows a lot of changes in your production, it duplicates your batch environment from e.g. test into production environment.
    A perfect set of tools is available to support all necessary activities. Replicate or copy your batch production environment or specific parts of it. All jobs and other JCL components will be downloaded, which are part of the previous unloaded scheduler data (this is normally an unknown part) All interface which results by unloading parts of a production work flow will be marked.
    Jobcontrol and scheduler data may be modified to meet specifications and guidelines of the target system! It is possible to create 'DEFINE GDG' statements based on unloaded jobcontrol for all new dataset names. EXCLUDE lists may be created to ignore certain interface problems. All change definitions will be logged and may be reloaded on demand to allow reruns of modifications at any time.

    Replicator Präsentation

    Using our software tool >> BATCH REPLICATOR << during the takeover of a bank's datacenter essentially contributed to process this migration quickly, within the shortest time possible. About 720 different change instructions (old> new) approx. 172.000 modifications in IWS (TWS, OPC).
    No problems and errors caused by these changes were deleted at production start. You may get more information downloading our presentations and other documents.


    Jobman Screen

    Tool JOBMAN is a very special modification service, which allows users to make changes in freely selectable JCL files. It allows to change all JCL objects, to add JCL parts and whole steps.
    JOBMAN can easily be integrated into existing handover procedures!

    More about these tools in the form of documentations and presentations you can see in our download area!



    RACF Compare

    As part of several LPAR consolidations we had the task to move whole systems into other sysplex environments. One of the serious problems was to consolidate RACF databases. Here we had to determine whether generic profile definitions lead to logical overlays and therefore to unexpected results on the target system.
    To be able to compare these definitions, a program was developed to achieve this highly complex task.

    IWS for z/OS Web Interface

    The IWS Focal Point is used to control several IWS controllers on different systems. The displayed information is created by a started task and stored as HTML files on a mainframe system. This data is browsed using a webserver with an automatic refresh logic.
