Dataset Analysis

OL-DS-SERVER talks to a remote data server. OL-DS-LOCAL is the same workbench when CoreIQ runs on z/OS. Both expose Browse, View File, and View Logical File.

View File

Open dataset content to inspect bytes in the hexadecimal viewer. Set Dataset Name, Limit, optional Skip, or Range. Use Execute, or Load binary file from the load menu. Check Parse binary (COMP/COMP-3/numeric) to decode packed fields. When Common Regex patterns exist, Filter by regex is available.

The Search panel builds a filter expression from available fields (Ctrl+Enter to run). Skip and Range are disabled while a filter is active.

On keyed VSAM, Next / Prev page by key cursor, not numeric offset.

Look up one record by key

For a KSDS cluster, type a record's key in the Key box and select Execute. View File shows that one record instead of a page. This works in every layout mode, including TLV fragments, and needs no record-change permission. Clear the box to page again.

The dropdown in front of the box says how the key is read: Key (padded with spaces, as the ID column shows it), Key (low-values), Key (high-values), or Key as HEX (the key's bytes, such as C1C2 or x'C1C2'). The published dataset API's read by key (.../pk) takes the same choice as keyMode.

A key that matches no record answers 404 (Not Found), not a sign-in error. A key given as low-values, high-values or hex is named in hex in that message.

Rename fields

Click a field's column header to give it your own name. The name is saved with the dataset's record layout and is what the published dataset API, its Swagger schema, filter expressions and orchestration flows use. A name must be unique within the record, ignoring case; a rename that clashes with another field is refused when you save.

Record layouts

Use Associate Source to paste, upload, or select COBOL copybook source; use Select Model to apply an existing catalog layout. After a layout is associated, insert, update, or delete a row when the endpoint extras allow it (defaults: update on, insert and delete off).

The Task List tracks progress. Associations are stored in the host's Datasets catalog.

For copybooks with nested REDEFINES, use the hierarchical selector. Lock an option to retain it, mark one for deletion to remove it, and save pending layout changes. New associations are pending until approved.

See View Logical File for resolving a CICS file or JCL DD name.
