CICS CM CHECKSUM in package display

In CICS CM when viewing the components of a package via 3.x.2, displaying the checksum with packaged components would save customers time by allowing them to verify checksums of components in a package at one time.

    Thank you for raising this RFE. I hope that the suggestions we provided, will help you to get the checksum details you require.

    Hi Curtis, Note that the CICS CM Package List view provides details of the Key Association Checksum as explained here:

    • When a resource is packaged (i.e. the KEYASSOC record created) checksum x'00000000' is assigned to the KEYASSOC record.
    The value of x'00000000' indicates that this is a Not ready, new object.


    • When READY is performed, the definition on the CSD/context is read, a checksum calculated say x'8DA5BF65' to overwrite the KEYASSOC record's value.


    • When MIGRATE occurs, as the resource is copied the KEYASSOC record is propagated for association with the target Config and the checksum reset to x'00000000'.
    That is, for the target Config it is Not ready, new object.


    • When READYLST processing occurs, the KEYASSOC checksum is compared to a recalculated checksum for the CSD/context definition:
    • If KEYASSOC checksum is x'00000000' the packaged resource is shown as Not ready, new object
    • If the CSD/context resource is not found, the packaged resource is shown as Not ready, object not found
    • If the KEYASSOC checksum matches the CSD/context resource checksum, the packaged resource is shown as Ready
    • If the KEYASSOC checksum does not match the CSD/context resource checksum, the packaged resource is shown as Not ready, object changed

    So CICS CM is interpreting the checksum information for you and providing the status for each object. If you still need to review the Checksum for each resource in the list,
    and the actual resources on the CSD you can use the Menu pulldown and Option 3 CICS Configurations - then review the resources by specifying the Group name for the
    resources in the object list and using CHECKSUM FULL command to display the Checksums.

    Please let us know if this helps.

    Checksum facility is currently available only in report sections. In case of packages containing many similar definitions, there should be fast way to compare it (via checksum) directly within package (in object list) - to check if definitions are the same, or mistakenly contain some differences. Comparing it via reports is time-consuming and error prone. Suggested enhancement would dramatically improve/fasten package verification.
