DASD SHARED default YES in HCD dialog

Our customer encountered data integrity problem for the user catalogs and the DASD datasets in the data warehouse system because a lot of USBs were SHARED=NO. Then it could not update the databases for a few weeks.

So, our customer strongly requests to update HCD from the view of fail safe when they defined IODF unexpectedly.


Now when our customer set blank(space) in the SHARED feature in the HCD dialog, its UCB defined with SHARED=NO. Its default is SHARED=NO.

It should be SHARED=YES considering the impact caused by mistake.

Could you please change the SHARED default from NO to YES ?

    Hello Teruaki,

    many thanks for helping us to improve HCD. We understand the overall intention of your proposed requirement. This is a useful enhancement to HCD and we will move it to our requirement list (although no "more information" was provided).

    But be aware:
    Since the content of our next release is already defined, we will move your request into our long-term queue.

    Kind regards,

    Hello Teruaki,

    Default values for features (like SHARED) are determined by the UIM (not by HCD).
    When you define a new device-to-OS connection in the HCD dialog this default is used to prime the dialog (e.g. for SHARED the default value is YES).

    When you type a _non-blank_ value different from (a prefix of) "YES" or "NO" (e.g. "ABC"), you will see an error message stating that the value is not supported. You are prompted to enter (a prefix of) "YES" or "NO".

    Only when you overtype the default value with blanks, HCD will interpret this as "NO".

    We propose to change this behavior so that a blank field is treated like other unsupported values. I.e., you will see an error message and are prompted to enter (a prefix of) "YES" or "NO". This seems safer than quietly interpreting a blank field as the UIM-defined default value (which may be YES for some features and NO for others).

    Would this change in the HCD dialog be helpful?

    Thanks in advance !

    Kind regards,
    Your HCD Team

    Should the UIM be changed ?
